iPhone OS 3.0 causes overheating problems?

Written By Unknown on Monday, June 29, 2009 | 7:08 AM


Recently a discolored overheated iPhone 3GS was discovered and blogged about on blogs like Gizmodo, Engadget, and PCWorld. I'm not 100% sure, but I do think that the overheating problem is being caused by the iPhone OS 3.0 software update and it isn't affecting the iPhone 3GS only, it's affecting other iPhone and iPod Touch devices as well. After updating my iPod Touch to 3.0 I did notice that it got warmer whenever I plugged it in to charge it or played a game. I just did a quick search on Twitter, and it looks like I'm not the only one who has experienced this. I expect Apple to fix this in their next iPhone 3.0.1 or iPhone 3.1 update (which will hopefully be soon!). How has your iPhone OS 3.0 upgrade experience been so far? Do you have overheating problems because of iPhone OS 3.0? Leave a comment below.

Yup. Overheating badly. Couple times after charging it gets really hot that it discharges my battery and dies and asks to connect to itunes. 3.0 on iphone 2g. Fail! Didnt happen before when running 2.x.x.

June 29, 2009 at 7:51 AM

HAHA! Yea I've been wondering why it gets so hot whenever playing a game or charging.. that explains alot.

its me
June 29, 2009 at 8:29 AM

there is a thousends of people (iphone owners) hey have the same probl. mine is overheating too every time i play a game, or charging or when im on the net and my battery is discharged too. Soo 3.0? -I hate this version :) yeah and need spothlight switcher too couse i dont like it and no way to disable it :(

June 29, 2009 at 9:01 AM

Yes most def...very hot when ever I'm active on my iPhone 3g for more then 10min,almost doing any activity..

June 29, 2009 at 9:07 AM

I haven't had any problems from my 3.0 upgrade. But on another not, I jailbroke my phone using redsnow. It was fine for a couple days. I woke up this morning to find my phone crashed in the middle of the night. It took an hour to get it running so I could restore it. BEWARE OF REDSNOW BEWARE

June 29, 2009 at 9:12 AM

I have not experience the overheating but for some reason it tends to slow down alot kinda wierd I think the search is not that accurate with the phone. I have an 8gb 3g and over 800 songs and two movies little bit of apps when I go to search my keyboard often sticks on the pages of my application why is my pjone slowing down

June 29, 2009 at 9:22 AM

Yea had noticed this
used AC outlet and it didnt heat up as bad
done a temp test with a eletronic thermomiter
The temps where high
I also tested with my iphone 1 g 3g and 3gs roughly the same temperatures
My guess apple coded 3.0 in such a way its stressing out the CPU causing it to over heat
Or its taking power in too fast
the over heating only ocours tho when the phones on and doing some activity
I reccomend restarting your phone every now and then
Restores some RAM back the system that was taken up over time.

June 29, 2009 at 9:32 AM

i've always experienced overheating... since 1.1.x... maybe i think it's overheated and it's not that much haha... but if it isn't... then i haven't had it for 3.0 either :P... it gets as hot as always...

June 29, 2009 at 9:36 AM

Mine doesnt over heat or anything. i have a ipod touch 1g running the iphone OS 3.0 and i like it and im not haveing any problems with it.

June 29, 2009 at 9:56 AM

It's a shame. Spotlight searching and the horizontal keyboards are very handy, but the iPod app runs like a sick dog and the battery life is a fair bit less on 3.0. I appreciate that Apple are still supporting the iPhone 2G with these updates, but it doesn't run very well at all.

Hopefully a 3.0.1 or a 3.1 will come out soon...and be jailbreakable...

June 29, 2009 at 10:02 AM

Yep. It turns in to a nice hand warmer... :)

June 29, 2009 at 10:10 AM

Dido... Especially when I'm on the net. I can feel it through the skin and the clear case on the back. It gets as hot as my XBOX did before I bought the cooling fan. It's getting hot right now.

June 29, 2009 at 10:22 AM

yep so true my iphone 2g gets hot verry quick aswell esp.. with the new 3.0... also i have noticed that the battery life gets drained allot faster :/... getting a bit worried that my iphone might brake down on me :/.....

June 29, 2009 at 10:31 AM

A little warmer yes but my biggest issue is now iTunes won't backup my phone now when ever I plug it in. Why can't apple EVER release a new firmware without any bugs?

June 29, 2009 at 10:39 AM

Thank god i did not update to 3.0 the day it came out. I feel that ppl that have jailbroken phones should wait awhile to see all the bugs that come out. If youve had 2.x.x for 3 months or w/e why cant u wait another 2 weeks to see the issues. hahaha

June 29, 2009 at 10:59 AM

Yes! It got hotter when I upgrade to OS3.0. Not just hotter but also eat up my battery....especially when I connect using WiFi.

June 29, 2009 at 11:22 AM

I have noticed since the 3.0 update that my black 3g has been getting very warm when charging, and while using the phone while plugged in, and my battery life seems to have dropped off quite a bit I used to get 4.5 to 5 hours out of it now I get around 3.5 hours with the same type of use...

June 29, 2009 at 11:22 AM

yes! when PUSH is enabled my iphone gets hot and battery drains so fast like less than 5 hours even on stanby

June 29, 2009 at 11:25 AM

Yea I'm having the same problems.
My iPhone 3G will overheat so bad it'll stop charging and start discharging at random points in the charge
it turns out that when that happens I have to leave my iPhone Alone and do nothing with it for 2 1/2 hours. If I use it. It turns into a hand warmer

June 29, 2009 at 11:38 AM

I was listening to music 1 night and i put my iPhone 3g on the charger so it wont be dead when i wake up and when i woke up not only was the phone dead but it was so hot i couldnt even touch it.

June 29, 2009 at 11:57 AM

So far my ipod touch 1G on 3.0 hasnt been having the overheating problems only having wifi issues that are hopefully fixed

June 29, 2009 at 12:00 PM

I have noticed a slight increase of temperature in my Touch 2G when i upgraded to 3.0

June 29, 2009 at 12:09 PM

whoa I was just gonna update to 3.0 and jailbreak today but not after all this stuff is going on haha! I think I'll just wait now and see what happens.

June 29, 2009 at 12:48 PM

I haven't upgraded to 3.0 yet but my jailbroken iPod touch with 2.2.1 (I think) overhears when plugged in, dunno if this is because of the time it got soda spilt on it or not though

June 29, 2009 at 12:50 PM

Mine's hot too. And got slower to open Apps and to write text...

June 29, 2009 at 12:55 PM

I noticed that the battery life got shorter and the iphone is indeed a bit hotter. Hope they fix this problem. Like an hour of music theiphone's battery has only 40 percent.

June 29, 2009 at 1:07 PM

Mine doesnt overheat. Im running os 3.0 jailbroken/unlock tmobile. I dont have any problem with new firmware.

June 29, 2009 at 1:16 PM

My touch 1g overheated right after I updated but when I restarted it the temp was normal. It has been fine ever since.

June 29, 2009 at 1:34 PM

I have a jailbroke ipod touch running iphone OS 3.0 and it does overheat when plugged into the computer, but it dosent crash and it does just fine when using it or if it is plugged into the wall

June 29, 2009 at 1:44 PM

I would tell u but I'm still waiting for the 3.0 quickpwn

June 29, 2009 at 2:11 PM

my jailbroke iphone3g overheated every night while charing next to my bed, and i found it 3.0 consumes more battery than 2.2.1 !

June 29, 2009 at 2:14 PM

Yep. Definitely. Apples going to owe big bucks!

June 29, 2009 at 2:16 PM

I found if I have notifications on in 3.0 my iPhone 2g gets realy hot while charging and other various programs.

June 29, 2009 at 2:18 PM

running iPhone 3.0 and having issue on wifi.
Reset, update, restore or any method you can name, will not fix the problem. i did reset/restore for more than 10 times and no luck.
Few days back, I did freezer trick and got wifi working for few minutes.

It's definately overheating problem.

June 29, 2009 at 2:30 PM

Before upgrading to OS 3, my iPhone 3G battery lasted for at least 2 days. Now, it barely last for a day.

apart from that, a lot of apps from Cydia do not support OS3 yet, which is really a pity. My phone is almost naked without those apps and does not last for long anymore.

Hoping for a soon release of further upgrades.

June 29, 2009 at 2:30 PM

My iphone 3g after the update did heat up a bit, and the battery drained 10% an hour when idle.

I had to changed mail Push option to off , and set all my mail account to fetch manually.

Now it no longer overheats, and battery life is preserved.

June 29, 2009 at 2:30 PM

That was the FIRST thing I noticed when I got my 3Gs.

June 29, 2009 at 2:33 PM

I do not know you but my iphone 2g state is overheating to me before putting the OS 3.0, this is still overheated me with OS 1.1.4 and I state to overheating so far I see no difference with respect to overheating.

June 29, 2009 at 2:39 PM

I noticed that ever since I upgraded my iPhone 2g to 3.0, I got slower response, The Battery life dramatically changed, It got shorter and I have to charge my iphone everyday unlike when I was using 2.2.1FW. I also noticed that everytime I charge my iphone, the back panel is very hot.. Is this going to cause problems for my Iphone? I'm worried that it might cause bigger problems..

June 29, 2009 at 2:39 PM

mi iphone doesnt have that sort of troubles, its running 3.0 and everything is good!

June 29, 2009 at 2:42 PM

My 3G is slightly warmer with 3.0 and definitely slower and more choppy. Its due reduced free RAM - all that new stuff (index search, accesory daemon, copy/paste) takes up RAM but I am sure with better tweaking, they can fix this. Or do they force us to buy 3GS? That would be shady tactics not common to Apple...

June 29, 2009 at 2:46 PM

Weird. Running my 2g and 3g and 3gs all with a stress test on os 3.0 tried it all jailbroken and non jailbroken, I have no problems and they are all in a case! Not only did I stress it but I ran downloads games and everything I could try even put them all under a pillow at the same time and nothing...I'm running AT&T for those concerned.

June 29, 2009 at 2:50 PM

I notice the heating. My iphone 3g heats up pretty quick when i switch on music on the speakers, when i charge, when i surf or just leaving on the table and a noticeably, the battery life was cut down by 60%. A fully charged iphone and 15 mins of use drops to half the battery. First I thought it would be the expectancy of my battery life but this happened right after i updated my 3g iphone to os 3.0. Hope apple will deal with this problem.

June 29, 2009 at 2:52 PM

Same problem here... Overheating problem even without using it, thats why i restore it again to 2.2.1 but with new baseband:)

June 29, 2009 at 2:59 PM

Hi just to let u guys know that am running 3.0 on my 3g iPhone and everything is fine. Playing games browsing the net listening to music and still the phone doesn't heat up. Maybe it's just certain models of the iPhone that's having this problem.

June 29, 2009 at 3:06 PM

Oh yeah you got that right, I am using itouch 16GB and iPhone 16GB, and both over heat while using wifi in an hour... this started happening after i upgraded to 3.0 OS....i find the bellow bottom part near the battery charger connection to be heating up more than the rest of the body...

June 29, 2009 at 3:16 PM

I'm actually having less over-heating on my iPod touch 2g running 3.0. But all kinds of other problems.

June 29, 2009 at 3:18 PM

I have a jailboken 3g with 3.0
My phone does get hot at times.
My slider screen wont slide at times.
My keyboard pauses and then quickly tries to catch up with what I've typed.
It takes about 6 seconds to go into the message app just so I can view or write an sms.
Generally slower than before.

June 29, 2009 at 3:19 PM

I new I wasn't getting crazy .... We have 2 iPod touches and 1 iPhone in our family and all of them got very hot when I'm playing music or whaterver. I wonder that affect the battery life?

June 29, 2009 at 3:29 PM

I have noticed some increase in heat on my 16gb 3G, but not to the point I can't pick it up. I have noticed a huge decrease in battery. At times it drains as fast as a percentage per 1-2 minutes. I've been playing games as much now as I did with 2.2.1 and my battery is draining 3x as fast.

Nick, I don't think there is gonna be a quickpwn for 3.0. Redsn0w is the only jailbreak for 3.0

June 29, 2009 at 3:35 PM

I'm on my iPhone right now and when I started my last message I had 36% battery. I am now at 24%. That's less then 10 min of Internet usage. I have push turned off and 3g off. I have disabled everthing I can go without just to try and save as much battery as I can. Still no help. Anyone else losing battery as fast as I am?

June 29, 2009 at 3:36 PM

Yesterday I noticed the overheate after I removed the case to plug a TV out cable, I have OS3 jailbroken.

June 29, 2009 at 3:38 PM

I have a windows and I'm pissed. Also my iPod over heats and it pisses me off. My battery life sucks and I want 2.2 back:(

You can use redsn0w to jailbreak! Go to http://www.quickpwn.com/2009/06/jailbreak-iphone-os-30-with-redsn0w.html.

June 29, 2009 at 3:38 PM

I've updated and jailbreak my iPhone 3G to 3.0 and never faced any overheating issue.

June 29, 2009 at 3:52 PM

One time I was charging my iPod touch 2nd gen and when to pick up but dropped it because the heat shocked me so.

June 29, 2009 at 3:52 PM

I had a problem with it overheating when playing games and charging. Also found it to be freezing up more and the batery seems to be draining faster when on Safari or playing games. Back to the drawing board Apple!

June 29, 2009 at 3:54 PM

No problems here. Maybe a smidge warmer, but only noticable while charging and under heavy use. Battery life seems normal too. I am synced with an exchange server too, so push email isn't hurting.... Least not me!

June 29, 2009 at 4:19 PM

I guess one good thing about using unlocked tmobile, No 3g - as I haven't really noticed any Over heating. I also have a 1st gen on 2.2 that I think gets hotter than my 3g 3.0 (3g turned off) both on tmobile. I only notice them getting warm when I use an edge dependent app like emergradio or slacker. The reason for the discoloration on the white one in the pic is because the batterys are adhered to the inside of the back cover.I wouldn't assume it's 100% because of 3.0 but rather a combination of running a few of 3g/edge dependent apps on 3.0 and GPS while plugged into a car charger(non OEM carcharger w/o failsafe maybe??) Now if that happened while just strickly charging the batt on an approved apple charger than I would worry but as stated it happened while using GPS and I would almost bet it was attached to a car charger while running GPS for hours on end. If you think your iPhone is getting to hot while charging you may want to check and make sure that your charger was purchased post recall (should see a green dot where it plugs into the wall post recall) check with you local apple or AT&T store. And use caution while using GPS (or any 3g/edge dependent app) and charging at the same time especially if you are using a car charger as alot of car chargers don't buffer the current like an OEM house charger.

June 29, 2009 at 4:21 PM

Running jailbroken 3.0 software on my 2G touch- no heat problems. Mine is in a hard plastic shell type case.

June 29, 2009 at 4:21 PM

I only own a 1G iPod touch that has eaten some redsn0w, but no problems with it at all. it has always warmed up when using higher quality (graphics really) games, but the 3.0 software runs very well, better than 2.2 I had. I can picture this problem with the 2G touch and maybe the 3G, but for the native software on a 3GS device is unspeakable, shame to you Apple. Desktops are fine for getting hot, thats JUST WHAT they DO. but for laptops and iPhwns, consumers will not use them if they can't easily hold it!

games like Zombieville USA and Pocket God and SpawnLight and Spawn Illuminati run fine (the last two run great and are very entertaining), just slightly more warm, but i don't understand why TowerDefense ALWAYS drains my battery the fastest (ties with video) that needs to be fixed.
as far as the PINK being a fake, i really think its plausible, 'cuz they do get HOT. I do use an Incase slider. (protect your investment, and don't be careless. Don't let this happen to your phone, if its getting hot, let it cool off.)

Yes I am a PC. and i still can't believe they can't figure out how to have a better heat dissipation system in a handheld device.

i have an iphone 3g 8gb
and ive noticed its been hotter when i plug it in the charger but i ignored it, and last night my cousin pointed out to me that it was hot and today i saw this, it there a way apple can fix that or what is there to wait for?

June 29, 2009 at 5:08 PM

Yes i have same problem on my 3G OS 3.0.

June 29, 2009 at 5:09 PM

Yeah, just a little warmer, but I didn't saw it like a big deal... I guess it is. If you charged while it's off, this probably won't happen. I didn't have any probs with my Iphone 3g so far, I hope it doesn't get burned lol, no, seriously it cost me 400 bucks!

C'mon Apple stop doing sauce if you don't know how to do it...! lol

No, seriously APPLE fix this sh!t, Thanks!

June 29, 2009 at 5:19 PM

Yes me too...anytime...

June 29, 2009 at 5:30 PM

Yesterday I installed and jailbroke OS 3.0 on my ipod touch 2g. I haven't still experienced problems with overheating though but I did notice the slower work of apps. And as I see now it wasn't just the result of my high expectations that OS 3.0 will have better perfomance and manage apps quicker because people here tell the same problem.

Also I noticed that if to unplug your fully charged iPod touch and then plug in again, little battery on top right connor of the screen will show "lightening" that it's being charged again(!) instead of "fully charged". This never happened in OS 2.2.1 and lower.

June 29, 2009 at 5:47 PM

Yeh - here too - hot to the touch. No problems on an overnight charge.

June 29, 2009 at 5:54 PM

Yeah i updated my new iphone 3g and it does get a lot warmer. Also the battery lasts 2 hours on low brightness. This is what i hate about 3.0.

June 29, 2009 at 5:54 PM

Yes, I noticed it, but it only happens when I charge my iphone using the power outlet. If I use my computer to charge it through USB, the problem doesn't exist. About the battery life, I actually see the opposite. After I upgraded my iphone to 3.0, the battery life lasts much longer than the 2.2.1. However, when I was playing around with my phone and turning on the changeable background theme using winterboard, the battery life lasted very quickly. After changing it back to use the non-changeable theme, the problem disappeared.

June 29, 2009 at 5:57 PM

ever since i updated it my battery percentige drops quick...i play apps on it 4 lyk an hour and its already half way...b-4 i played about 3 hours and had half way left...and its been gettin hot...

June 29, 2009 at 6:02 PM

Yeah a lil warm but I noticed that it slows down to a laggy interface when playing the same game for about an hour. They really need to fix it.

Gee digital
June 29, 2009 at 6:02 PM

I got a 3g S. And I am not having any problems at all... What's all this about. ... Apple is trippin

June 29, 2009 at 6:04 PM

Yep, overheating AND battery draining too fast!!!

June 29, 2009 at 6:04 PM

why this overheating, is it software or some other

June 29, 2009 at 6:08 PM

iPhone 3G 8gb upgraded to 3.0 jailbroke with redsn0w. No problems here

June 29, 2009 at 6:23 PM

Problems here as well with 3.0. Overheats a bit while playing a game or browsing web/youtube for a short period of time. Also battery life has decreased a great deal, which is an even bigger problem for me, especially since the iPhone even before lasted like a day at max.

June 29, 2009 at 6:45 PM

Since upgrading I've had a problem with overheating & the battery too I get max 4-5 hours if I don't use it! I thought it might be caused by jailbreaking but it doesn't seem to be. Hopefully this will be fixed soon :(

June 29, 2009 at 6:54 PM

hey guys!

just reset your iphone/pod in settings to zero also network settings
on iphone disable 3g!
and you´ll go off with this problems

June 29, 2009 at 7:20 PM

My iPhone 3g gets a bit warmer but nothing to worry about..BUT my battery life has decreased ALLOT!! I use to get a max of 2 days but now I'm lucky to get untill 11pm..and it is MUCH slower. Does anyone else have these problems??

June 29, 2009 at 7:40 PM

I have the iPhone 3GS and mine gets very hot. Normaly when using the maps app on 3G.

June 29, 2009 at 7:42 PM

I too have noticed the iPhone 3G overheating under 3.0 firmware and so far am not impressed whatsoever with the new firmware update.

Admittedly the 3G is now faster and apps do open faster however for Apple to give extra performance like this something has to give surely....yes you guessed it.....the battery too!!!

My battery is 50% worse now i am on the new operating system and using Safari or other 3G usage, or charging means the iphone gets very warn in the bcentre on the back.

the battery wasn't all that great to start with therefore it's now worry that this firmware seesm to overclock the iphone to get better performance but mgiht be reducing the life of these great phones....

What do you all think??

June 29, 2009 at 7:50 PM

I've got an iPod Touch 1G with OS 3.0 on it, but i haven't experienced any heating problems yet. Maybe it's caused by having too many processes on the background? (like push, 3G, GPS, Bluetooth, Charging, watching a video etc.)

June 29, 2009 at 8:38 PM

I have an iPod touch 1G and updated it on 3.0 and jailbroke it. It's getting hotter and hotter if i play a game. This is a problem with the 3.0 firmware update. I didn't think so much about it, but after I read this, i do. I hope there is an update really soon!

June 29, 2009 at 8:57 PM

I've got a 32gig iPhone 3Gs and I haven't had any over heat problems, my touch use to overheat alot but the hard drive was always full and I could cook bacon on the back of that easily lol it was on 2.2.1 and it would take over a min to turn it on

June 29, 2009 at 9:04 PM

Hello, yes i have the overheating problem, iphone 1st gen 8GB

June 29, 2009 at 9:08 PM

My iphone 3g is warmer when in charge (outlet) but i think not overheat!
it just a little warmer. in os 3.0 battery life extremely increased compared to 2.2.1 and lower! and new features are really nice!
but Apple MUST SOLVE the overheating problem that somebody has ASAP...

June 29, 2009 at 9:10 PM

yup...heating and undercharging problems as well as battery draining unusually...had to turn off location services, notifications and 3G...then all went well... have an iphone 3G on OS 3.0

June 29, 2009 at 10:44 PM

I have a first gen iPod touch and it runs cooler now with OS 3.0 then it did with 2.2.1. It was jailbroken when I updated it therefore I have a different "carrier" title and oddly still have a percentage next to my battery. My battery life has similarly improved slightly. I also use the free memory app after long use of safari so it doesn't lag when I type or play some of my larger games. Also I heard that the "overheating" and draining batterylife on all iPhones was mostly due to more I mean much more frequent GPRS use even when locked. Just my $0.02

June 29, 2009 at 11:09 PM

Yeah that's true that after update to os 3.0 is overheating the iphone. But is not only that sometime my phone is frozen too. The jailbreak with redsn0w there is no problem successful.

June 29, 2009 at 11:16 PM

iPhone 2G 16gb upgraded to 3.0 jailbroke with redsn0w. No problems here

June 29, 2009 at 11:56 PM

I had my iphone 3g 8gb overheating it would get very hot and then battery power was lost all the time. It did it just for 2 days then i did a complete restore and redid the phone like it was brand new and then jailbroke and unlocked it and now it is perfectly fine. I think it might be sommething with it being unlocked and jailbroke and the new 3.0 firmware all at one time that is giving it to much to handle so its just burning up. I dont know but i did the complete restore, format, jailbreak and unlock and my iphone is now a+.

June 30, 2009 at 12:23 AM

Has anyone noticed that when texting u start off hearing the clucks then it suddenly disapeara and u don't hear the clicks running 3.0 on 3g S and it too overheats. Apple fix this ASAP!!!

June 30, 2009 at 12:25 AM

My touch 1st gen has been warmer but i havent noticed anything to extreme other than when i charge it, then its actually hot to touch
but lets hope apple fixes it.

June 30, 2009 at 12:49 AM

yea this problem has happen to me but my phone is fried it didnt turn on or anything now im waiting on the fed ex guy with my package that was suppose to be here yesterday but the had the wrong address.. iphone 1st gen also

June 30, 2009 at 1:00 AM

Well looks like everyone's havin same problems with OH (overheat) Apple's chairsman made an announcement this morning, "all the 3gs will be removed from market since the bad CPU tolerance to the extremely ammount of data handled by typical apps" also they blamed most DevTeams for posting blogs with out of context information regarding this malfunction since the OH is due to a simple modification on programming, Apple will release a 3.0.1 update this friday on Itunes sepparately for older versions of 3g, itouch 1g, 2g and 3gs already purchased, also they will offer a exchange on 3gs for those who are havin OH on their newly accquired pieces of #%^*.

June 30, 2009 at 1:03 AM

i dont even have 3.0 yet. it wont install, i keep getting error 1602 and 1604, stupid apple, it gets stuck on the plug into itunes screen and comes up with an error and i can install bak to 2.1.1 but i cant go upto 3.0 :S i wish i could experience this over heating but i aint on 3.0 !

June 30, 2009 at 1:31 AM

I was looking at the back of my ipod touch 2g 3.0 and it looks like there is some trange lines. (some sort of crosses and it repeats it's self for 4times or more. On each side i got also a long line of black shit. Cant get it way. Never had this before 3.0 upgrade. Apple beter give me a new one.

June 30, 2009 at 1:43 AM

"I own an IPhone 3G OS 3.0 jailbreaked/unlocked with Redsn0w"

Yeah it happens when I charge the IPhone in the car and start the gps, the device gets really hot. Also when I play music and turn on the gps!! ( Navigon Mobilenavigator)!

June 30, 2009 at 2:17 AM

Yeah, my 3G running 3.0 jailbroken firmware had an overheating problem while plugged into my car charger and listening (streaming) last.fm. I've also noticed a bit shorter battery life, but that just could be all my recent tinkering.

June 30, 2009 at 2:52 AM

Redsn0w doesn't work on my laptop. It makes cydia crash and keyboards won't work. It's shit!! I don't have a mac and quickpwn doesn't have 1 4 windows!!!

so I jailbroke my Iphone awhile back before the new 3.0 software came out and when I go to download the software it loses my hack and goes back to the regular iphone way again...why is that ? can i get it back with the new 3.0 ?

June 30, 2009 at 5:14 AM

Over heating solution:

I have 3 iPhone's: 1 3g, 2 gen 2.

I just adjusted my push options to never and reset my carrier file and it stopped heating. I think the problem must be in the carrier settings but I couldn't tell you without restoring my phone then test each option. Anyway, turning off the push saves the battery.

June 30, 2009 at 6:13 AM

I have 3gs & have no overheating problems no matter what I do. I have the metal ifrog case. My girlfriend has the same case with the 3g running os 3.0 & her phone got pretty hot when I was jailbreaking it & surfing Internet while hooked to computer. I was also teathering

June 30, 2009 at 7:52 AM

I have iphone 3g and i upgraded it to 3.0 and since then i see that it get over heated after using for a while and the battery life is a lot shorter also applications starting a bit late even when i press the home buttom to exit ,it takes alot more time than previous versions.
i have formated the phone like 5 times since i decided to upgrade to 3.0 and everytime i have the same result.
However , i am waiting for one more app to crash while i am using it , and if it happens again , i will downgrade to 2.2.1 again.
Also , i think there is something wrong with the ultraSn0w , the reason for saying that ,u will realyize it ,if u put the phone beside a radio and hear the on&off static ,then install the Ultrasn0w the put it back beside the radio , then u will realyize how many nonstop static u will get.

I have an iPhone 3G and after updated to OS3 my iPhone gets overheated and my battery life compromised. Actually I don't know what causes this to happen, it seems that after opening some apps, the system starts working wrongly.

June 30, 2009 at 11:12 AM

I have a 3G which I just upgraded to 3.0 and Jailbroke via redsn0w. The back case started getting extremely hot followed by a rapid discharge from 65% to 14% over 35-40 minutes. This happened again today, except I shut the phone off and started charging at 50%. I never used the map function since the last powerup. Only WiFi and data over cellular. I would guess that either the WiFi is stuck in transmit or the cellular transmitter is on full power. Unless the GPS receiver gets turned on arbitrarily without accessing the maps. These units have Lithium Polymer cells which are extremely sensitive to heat and over discharging. I would strongly suggest anyone who experiences a rapid discharge turn the phone off, wait for it to cool, and recharge it ASAP. Keep the charge above 75% until someone figures out exactly what is happening. Oddly, the phone has never began this "cycle" of quickly discharging when the charge was above 75% and it seemed to stop when the phone was powered down and charged.

June 30, 2009 at 11:23 AM

I have a iphone 2G and I upgraded to 3.0 and The battery goes down so quickly and it gets heat in 20 mins when i put for charge.

I was using Microsoft exchange and i was using push every 5 mins.. Then i switch from push to Fetch, now I don have that heating problem but the battery goes down quickly.

June 30, 2009 at 12:29 PM

having the same problem
iphone 2g. gets hot when im just listening to music or texting.
or when i charge it.
i found out that if its getting hot, try turning it into airplane
mode for about a minute, then switch back. its helps with the overheating and battery life alot

June 30, 2009 at 1:17 PM

I have found that apps not updated for 3.0 give my phone trouble (mainly the app just crashes). My phone has yet to overheat or discharge rapidly, but i have taken non updated apps off the phone and when they get updated reinstalled them. And so far im pretty much trouble free.

I haven't jb my phone yet but i have done 2 for friends who were to impatient to wait a month,(and yes both those phones have had discharging problems! but no overheating) I usually wait for bugs to be worked out before modding or hacking a new os.

1. If an app crashes reboot phone
2. Take off apps that haven't been updated for 3.0. Especially problem ones (leave them on itunes this way you will know if there is an update)
3. Be patient don't jb yet. there are alot of talented people ou there working the bugs out.

Since I upgraded my Iphone 2g, it presents three problems:
1.- Overheating.
2.- Drain battery in 7 hours.
3.- Low phone call reception strenght signal.
I´m sure the new 3.0 Firmware it´s guilty as charge. Hope there will be a new update soon that will fix those problems.

June 30, 2009 at 1:42 PM

My itouch 1g actually seamed to get hotter before I upgraded to 3.0 firmware. The only problem I have with it now is my wifi doesn't work from like 1am to 12:46pm??? I checked my wifi settings and there is no blocks so idk WTF is going on??? Plz help anyone?

June 30, 2009 at 5:37 PM

Hey everybody I am running the new 3.0 firmware and jailbroke with redsnow, my iPhone works great with no prolblem, the 2.2x firmware did warm up my iPhone but nothing that it didn't do when new right out of the box so I wouldn't worry bout it unless it starts to smoke, lol, or if it's too hot to touch, and there's never going to be a quickpwn for the 3.0 not from the dev team so red snow is the only way, but I found it works the same as the pwn tools but when you run the redsnow don't install the icy only install cydia or your phone will have bugs and it will run slow then after your done you can install icy through cydia, thanks hope this is helpful

June 30, 2009 at 10:17 PM

I did not notice elevated temperatures on my 3GS/32GB. However I noticed that battery lifetime is about 30% shorter than on my 2G/16GB.

July 1, 2009 at 1:16 AM

I upgraded my iphone 2G to OS 3.0, but my experience isn't good....However , i am waiting for one more app to crash while i am using it , and if it happens again , i will downgrade to 2.2.

I have 2 problem...
- Drain battery in 6 hours.
- Low phone call reception strenght signal.

July 1, 2009 at 3:25 AM

My 1st gen iphone gets really hot when I plug it into my car stereo's iPod plug. It worked flawlessly prior to the OS 3 update. Now, it gets hot and has a trememdous delay when choosing music to play (Via teh car stereo). When just using the thing, I see the battery drop at a rat of 5 to 10% per minute! For example: I had the phone charged to 100%. I read Sterling's post about the WiFi not working from 1am to 12:46pm. I looked at the control panel on my phone under restrictions to see if there was some sort of time restriction. It too no more than 2 minuts and my battery is at 81%! This is NOT the way it was prior to os 3!

July 1, 2009 at 3:46 AM

I bought the 3gs the first day it came out and didn't have over heating probs tell the third day I have a hard plastic case and It started to get real hot so then I took my case off and some of the plastic had melted on the case onto my new iPhone 3gs I was so pissed haha but I got the plastic off and it looks good as new can't wait for the jailbreak for the 3gs

July 1, 2009 at 4:35 AM

Haha I think apple did it intionoly for the iPhone 3gs so that they could find out how the dev team would jailbreak it then have a recall on the phone haha i can see apple doing this haha dahm you apple haha

July 1, 2009 at 5:27 AM

WTF, I now notice that when I charge it, the bottom of my iPod gets extremely hot!!

its me
July 3, 2009 at 9:21 PM

Hy guys i think i fix my battery drain problem,yesterdey i completly restore my 16GB 3G and jailbreak it, then back up, and my battery still drain qiuckly for an hour more then 10%, but after i turn off push, wi-fi joining and put my phone to charge for a night till the morning and huraay now its work great my battery is now on 95% but a playing games, listen my musics, watchin youtube, call, texting etc. so i use it and its great now Thanks God , so i hope its will work for you too Have a nice day :)

its me
July 3, 2009 at 9:23 PM

jeah and about the overheat, maybe its warm a littlebit more but i dont know if its not warm couse i hold it :) soo bye and hope best ;)

its me
July 4, 2009 at 11:19 AM

hey guys :) a still have 83% and its not warm, its really fixed

July 6, 2009 at 4:08 PM

I have the same battery life/charging/overheating issues. I think apple was focused on speeding up certain things, like safari, but in return left out some essentials, like proper power management.

July 6, 2009 at 8:49 PM

I have the same problem and I thought I was the only one cause everytime I watch a vid, play a game or just charge my ipod touch, it get really warm and sometimes even *hot*... hope there will be a fix soon....

July 7, 2009 at 5:02 PM

i am so so sad. my iphone 3G has the same problems. i jailbreak it using untrasn0w. same problem still occur.
some apps doesn't work. battery runs out less then 6 hours and my iphone becomes warmer sometimes hotttt... please helpppp

July 7, 2009 at 6:20 PM

Hey I've got the dame issue, I've got some advice though.
When you charge your phone put it on airplane mode it helps. After it's fully charged turn it off the same night. Wait till you wake up and turn it back on and take it off airplane mode. You will notice after doing this it will get hot again some day then do the oposite and charge regular and wait till fully charged and turn off till next day.
Hope this worked for you like it did for me.
But 3.0 blows!! But landscape does come in handy.

July 8, 2009 at 6:35 AM

you guys are all crazy you guys are just so fricking bored you have to blog about crap that isnt happening at all.... you guys are juts copying the idea of xbox 360 RROD and now saying the iphone 3.0 is a screw up OMFG what generation am i living in...
how can the fricking software update be the problem to "overheating" you plp are just plain out bored

July 8, 2009 at 6:37 AM

hey genius...
put off the 3G network..

July 8, 2009 at 1:36 PM


I'm sorry, but you are just a freakin' idiot. Of course software can cause overheating problems. Whether it's a full blown problem or a few isolated incidents remain to be seen. It could be a matter of the operating system or some component of it calling the processor more than necessary, hence extra processor cycles and more heat. Or maybe the WiFi is broadcasting to often. Perhaps the piece of software that regulates the charging cycle is the culprit. There are numerous ways the software could cause heating issues since all of the iPhone's hardware is driven by (guess what?) SOFTWARE! Very much like an operating system that has poorly configured power management settings can dramatically effect battery life on a laptop. I find it amazing that people like you who need a daily tutorial on which shoe belongs on which foot can come and spout a bunch of nonsensical rubbish all the while insulting people and then at the end of the day be entirely wrong! Software definitely CAN cause heating problems.

July 8, 2009 at 10:29 PM

I've had that since I got the 2.2.1 firmware update and I don't have any problems.

July 8, 2009 at 10:29 PM

YOU ARE AN IDIOT, this problem does exists.

how can the fricking software update be the problem to “overheating” you plp are just plain out
I cannot even know how a gentleman like you is asking this question, we live on 2009 you should already know basic stuff like this, off course the software may overheat the hardware, if a software has some fking bug that makes hardware be forced, it will overheat.

July 9, 2009 at 1:01 AM

upgrade to 3.0. overheating, when charging, txtin a lot. it actually at times will get stuck charging at say 65% even if its overnight. my reception is horrible. i have people leaving voicemails when my phone doesnt ring. i'm downgrading.

OS 3.0/redsn0w

July 9, 2009 at 9:27 AM

I have an iphone 3G with 3.0 and i haven't noticed
aaannyy over heating.

actually, mine is never even, warm.

July 9, 2009 at 1:53 PM

turning the push off fixes the overheating and battery life. on 3.0 i got 4 hrs of life and overheating. turning off the push i get more than 24 hours.

July 11, 2009 at 4:55 AM

This is a real problem, my 3G phone was upgraded to 3.0 OS and about two weeks later my phone started heating up and discharging very quickly. I recharged the phone, reset the phone, turned off wi-fi and bluetooth and again it started heating up and within 2 hours was pretty darn hot and discharged. I took the phone back to the store and showed them and they promptly exchanged it for a new one. The problem is real...

July 12, 2009 at 2:39 AM

don't ever leave your iphone charging overnight that's what causes problems. Because your iphone has a memory keeping charge data. if you charge it to long it won't ever really go to 100%. it will just say 100% when it's really lower the only I know to fix this is restoring the iphone. then my battery lasted longer.

July 12, 2009 at 5:45 AM

3.0 OS
16gb BLACK

I don't have any overheating problems, I use my living room plug through a extension cord when I charge it and it does get a little warm but it's always done that back when I bought teh 3G iphone last year. 3.0 OS has been hella good to me.

Jojo B
July 13, 2009 at 3:03 AM

I got the same issue with my iphone 3G with 3.0 installed. It started heating up and battery drains very fast. I think it has something to do with the settings. I just disabled the ff. it seems ok now:

1. Notifications: set to off
2. Adjust the brightness to about 20%
3. Auto-unlock set to 1 minute.
4. Turned off my bluetooth

Hope this helps.

July 13, 2009 at 7:32 PM

slightly warmer than before but not a big deal. as long it doesn't effect the use of the phone I'm good.

July 13, 2009 at 9:23 PM

Do you think that it is really about the update of 3.0 version? Because I have the same problem too. Ever since I updated my iPhone to its latest version, even if I just have it stand-by, the battery decreases rapidly. I wish that I should not have it updated if it really the case.
Is it also possible to bring back the older version of iPhone? (which is 2.0 i think. :))

July 15, 2009 at 9:40 AM

hahah. Your a genius kid..pure genius...now your gonna tell me metal doesn't conduct heat!

July 15, 2009 at 1:33 PM

Yeah I just upgraded to 3.0 on my iPod touch and it is definately running WAY hotter than it did, especially while charging. Might go back to 2.x for a whille til this gets fixed

July 18, 2009 at 1:12 AM

guys, i have the same problem, regarding my iphone(2g) update the new 3.0 version, problem is battery drained so damn fast.... need help ASAP!!

July 18, 2009 at 10:17 PM

Guys this is not actually because of OS 3.0...its because of too much processing on 3.0 which makes it hot...For eg: the computer running on Win98 stays cool compared to a computer running XP/Vista..its because win98 has very less processing to do and has only 5-7 tasks running when your computer is idle...whereas winXP/vista have around 40-48 tasks running when the computer is idle...So basically it is because of OS 3.0

July 24, 2009 at 2:31 PM

turning the push and notifications off and also turn off Mobile substrate Addons in SBSitting

July 27, 2009 at 1:25 AM

Ok, people. I'm here to tell you once and for all, SOFTWARE CAN CAUSE OVERHEATING PROBLEMS! For thos of you who don t believe me, leave your phone on, and CHARGING all fricking night. The, when you wake up, hold your iPhone/iPod Touch in your hand. I got hot, didn't it? I win, all you non believers lose. ^_^

July 27, 2009 at 11:17 AM

This is a REAL issue. I have a 2g iPhone, has been working fine. I upgraded it to OS 3.0 just a week ago. Right after upgrading, it started getting SO HOT and draining the battery so quick. Now I have to recharge it sometime 3 times a day! If I do not keep it plugged in charger, it'll be dead tomorrow. I have no doubt it is caused by the OS 3.0. I'm wondering if Apple is going to address it!

Please keep us posted with any possible solution. Otherwise, I'll be waiting for the next version of OS, hopefully fix it!

Does anybody know how to downgrade to OS 2.2 without loosing the information?

July 27, 2009 at 5:48 PM

Ya I have an iPod touch 2g on 3.0 and when charging it gets almost too hot to touch. It seems to be coming from the lower left hand corner it's quite bothersome.

July 28, 2009 at 11:12 PM

arguing on the internet is like winning the special olympics even if you win your still retarded

July 30, 2009 at 5:21 PM

im also having the same problem after i upgraded my iphone OS..
i hope apple would release a new OS to fix this problem..
it's really hard to charge the iphone almost twice a day especially if you're at work..

July 31, 2009 at 1:09 PM

I have the iphone 3gs and have the same overheating problem but only when I leave it overnight, it's because it goes over the 100% charge and needs to use the incomming energy thus overheating.

I am currently downloading the new 3.0.1 software which will helpfully fix this problem.

Also why are you only allowed 11 pages on the iphone 3gs I need at least 20, I filled it up with in a week.

August 1, 2009 at 10:31 AM

Specally when I use 3g. I turned off 3g now and much slow network
it must be fixed soon

August 1, 2009 at 7:33 PM

Same here, I finally decided to upgrade my iphone (2G) from 1.1.4 firmware to 3.0 using RedSn0w and my phone gets really hot while charging, and I think when I have my carrier, or my wi-fi activated it also gets hot while on standby! I hope they can quickly address this issue so I can update my phone with RedSn0w! People posting these comments all have jailbroken iphones right?

August 1, 2009 at 9:19 PM

I noticed on vacation that my phone was VERY hott... I thought that it might be a friek thing but I guess not. I just upgraded to 3.0 a few weeks ago... my phone is warming as I type... What a shame...

August 2, 2009 at 3:03 AM

I lost my WI-Fi connection!!

August 2, 2009 at 2:30 PM

Exactly I'm facing the problem of overheating ever since I upgraded my firmware to 3.0 and later 3.0.1. The New Firmware is causing serious trouble, overheating and battery starts to drain very quickly (Approx gives max 12 Hours standby time). I thought that 3.0.1 will also fix overheating problem other than sms venerability but same on Apple that they're unable to do so.

IPHONE 2G 4 Gig, Firmware(3.0.1).

August 2, 2009 at 3:31 PM

Mine gets really hot and will not hold a charge.

August 3, 2009 at 1:29 AM

Had experienced the overheating iphone problem, my 3G phone was upgraded to 3.0 OS and about 2-3 weeks later my phone started heating up and discharging very quickly. I turned off wi-fi and bluetooth, push off and again it started heating up and within 2 hours was pretty darn hot and discharged. I took the phone back to the store and showed them. They took my phone and after a week they exchanged it for a new one with an OS of 2.2.1. The problem is very real…

I was instructed to update again to 3.0 and restore 2X which I just did. Also, removed all apps that requires internet connection for the meantime. hoep this works

August 3, 2009 at 3:28 PM

I recently upgraded to 3.0 and jailbroke my 2G iPod Touch, and whenever iplug it in and am running games, or anything the back of the iPod right behind where the charge cable plugs in heats up to like 84º. And it never did that before 3.0.

August 3, 2009 at 10:47 PM

for everyone here i think i might no the reason ! the majority of you have jailbroken your itouch or iphone, am i correct? im thinking that may be an issue ! im not saying stop jailbreaking! im just saying it might be a reason that we should look in to, you all may be correct though! cause i have a iphone 3g maybe a month and a half old. first thing i did was upgrade to 3.0 and i had no problems. i also have a itouch 2g but i did not upgrade.

August 4, 2009 at 1:50 AM

Same issue, I noticed the extreme overheating when I plugged it to my itrip.. after a while maybe 30min, i felt the heat over the cover of the iPhone, I never experienced this heating before with 2.2.1, and just now is warm only with the charrging, apple launch the 3.0.1 official release, will fix the issue?

August 5, 2009 at 11:09 PM

Have iPhone 3G with OS3.0
Experienceing the same overheating problems and my device is not jailbroken...

August 6, 2009 at 5:34 AM

I too faced and continue to suffer with overheating and battery losing charge very rapidly. It started with 3.0 and next day updated to 3.01 and it got worst. Not sure what to do as it gets hot and can not hold charge.

August 6, 2009 at 6:27 AM

My experience was much worse. The overheating problem, the charging problem, the battery decreasing problem, and the app running problem(slow down)

August 8, 2009 at 1:48 AM

even i am facing this overheating problem.
now i am stuck on it.
whats the solution

August 8, 2009 at 8:43 AM

I was facing with this whole battery and Heating up issue also. But I think I found the culprit: EDGE. Whenever I put my phone close to a speaker it goes crazy! That means my phone is trying to connect to the EDGE Network. I have my APN settings (Under Settings > general > Network > Celular Data Network) to none because I get charged HUGE bills with EDGE but it seems like it's causing over heating & battery issues. Everyone Else who's experiencing this give it a try. Whenever I put in the correct APN Settings my iphone stops the whole feedback and my battery goes back to normal & no overheating issues. But whenever I take them off It feels like I can fry an egg in my iPhone!

August 8, 2009 at 9:07 AM

I second this:
My experience was much worse. The overheating problem, the charging problem, the battery decreasing problem, and the app running problem(slow down)

August 9, 2009 at 2:47 PM

The overheating problem is cosed by yahoo! messenger (in my case). after uninstall the app my phone came back to normal.

August 10, 2009 at 9:10 AM

I have the same problem with an original iPhone with OS upgraded to 3.0. Overheating sometimes. Also, the screen auto-lock doesn't always seem to be working, and that seems to be when the phone is overheating. And, yes, overall it is running really slow. And my email is also not working, although that may be an unrelated issue.

Anyone have a fix?

August 10, 2009 at 8:55 PM

I was having this same problem as well as extremely short battery life. I then restored my phone and set it up as a new phone instead of a backup, re-synced and set up my settings, and it stopped. The battery life still isn't quite what it used to be but it's not nearly as bad as it was. I don't really don't know why this worked for me, but it did.

August 11, 2009 at 1:17 PM

Aside from the battery, slow charge, and overheating issues, my iphone can't store songs into it. On itunes however, it says that the phone has all the music in it but it's definitely not there because the ipod within the iphone does not show any songs. Does anyone else have this problem?

B's PH
August 12, 2009 at 7:47 AM

same here,,,I had noticed these issues on my iPhone 3G also after updating to 3.0 and even my wi-fi started to get problems in detecting signal. I even tried updating it to OS 3.0.1 but still having the same problem, it get's hot easily when charging, using wifi, bluetooth, bad wireless signal detection. I hope too that apple will investigate about this issues before releasing new batch of iPhones in the future.

August 13, 2009 at 2:34 AM

Here is a solution that helped me: try downgrading from 3.01 to 3.0 via ITunes and then (if necessary) jailbreak/unlock with redsn0w. After unlock I just restored the content from a backup. After that my battery and iPhone went to normal. Hope this helps.

August 19, 2009 at 6:10 AM

OMFG!!! i totaly agree... my iphone 3g has been hotter... and i dunno why.. but i think its the battery... stil tanks for posting this thought i was the nly one expeiancing this problem.. ;p

August 30, 2009 at 12:02 PM

same for me.
i think the battery doesn't last as long either.

September 1, 2009 at 10:40 AM

Mine does too. I think its the push notifications. Battery charge seems to last less too. Also I'm in a hot town so I thought that was part of it. It will heat to the point where it won't charge. I hold it infront of the A.C. vent in the car and that cools it down enough to charge. Interesting that they've built a fail safe into the device to prevent charging and overheated battery. And also proof that the overheating is real and not imagined.

September 4, 2009 at 6:04 AM

My iPhone's problem is even worst, short battery life and cannot receive incoming calls. i restored it at least 3 times. At first, it worked fine; but when i connected my phone to PC and re-synced, problem happened again. So my experience is the phone will work fine if not re-synce it.

September 4, 2009 at 11:30 PM

poohbear, then it is probably due to an installed software, not the OS.

September 6, 2009 at 2:30 PM

I also have experienced the same. Like mojo I live in a warm city, I have actually, when charging it at home, placed the phone in a freezable drink cooler in order to be able to charge the phone while at home!

September 8, 2009 at 5:05 PM

Apple should make the new iTunes 9 capable to discover iPods and iPhones with OS 2. I got rid of that short battery life and overheating!

October 6, 2009 at 8:37 AM

same here

October 17, 2009 at 12:35 AM

i have the same problem too

October 17, 2009 at 3:57 PM

Yep, thought it was some fluke or something.... My battery life was like back when the SSH was constantly running. I can barely make it through a day without recharging it.
