So I overheated my iPhone 4

Your phone will still work, but you did shorten your battery life by about 10%. Although some chips might have melted a bit, they will continue to work. Also, instead of getting, say, 6-8 hours out of the battery, you will be getting about 5-6.

Other than that, your phone is undamaged.

If that was the case the warning message would pop up sooner. No point in having something to prevent damage pop up after the damage is already done.

I take my 3G into the sauna at the gym (usually 190-200 degrees) and haven't had that happen. A couple times when it was 210 in there I was a bit worried about the phone but it kept playing music like a champ.

It is surprising the phone tolerated it.
 
iPhone4 high on temperatur images

I did a hard reset but I do not know why this happened. In fact I hadn't used it for half an hour. Picked it up to make a call and it showed me the temperature sign.

Also, does anyone know a shorter way of shutting down all apps than manually doing it from the bottom scroll. I thought switching off and on would do it but it so happens that folks at apple want us to manually kill apps in the task manager. I assume too many apps their might have caused the temperatures to rise :|

I got the bumper. Its ok but now I don't want an external fan on my phone :p

This is the first iPhone I've had that I recall ever getting hot....perhaps we have another issue on our hands?

Imagine that, your electronic device gets hot IN THE SUMMER... quit trying to beat a dead horse and use every ounce of strength in you to find a new problem with the phone.. Do you even own a iphone4 or are you posting this from your "DROID"

It is not a task manager. The apps it lists are not running, unless you're listening to music through Pandora, or are uploading a photo, or whatever. It's simply a list of recently-used apps to make it easier to switch between a bunch of apps. There is no need to manually "kill" apps in the list. They don't consume power, don't slow down your phone, don't consume memory, and don't heat up your phone. That is the WHOLE POINT of Apple's multitasking implementation.

Hey Avalys. Thanks for responding..
I know the way multi tasking has been implemented but I was wondering if thats something that might have caused over heating so wanted to know some quick way to switch it off the sleeping threads. And having all those open in there kinna makes switching b/w apps slow.

Glass is a pretty good thermal insulator. This phone has a large heat-genrating battery and some power-hungry, heat-generating components sandwiched between two glass plates. Not the smartest design ever.

I was just randomly thinking about this today. Everything about the iPhone 4 is super sexy. But nothing about it seems very practical. From the antenna, to the breaking glass, to the fact that glass traps the heat inside. Apple needs to put a solar panel onto the backside and convert that heat into electricity to charge the phone. Though charging my iPhone heats it up to a certain point as well.

Yeah I'm pretty sure any sort of solar charging feature would not help with the heat problem....

I noticed mine get a little hot today, but just a little. It's such a compact device, we can't expect it to work hard all day and not get a little hot.

Haha! Ive owned every iPhone and i noticed this one gets hot in my house...I'm not hating on the phone but trying to contribute to the thread. I'm open to the idea that it's just my phone.... Get a life.
 
Here in Portland, we have had a slow start to summer. This last week we had temps in the 70s and 80s - compared to the previous few weeks in the 50s and 60s…
Yesterday while driving into the city, I had my iPhone4 plugged into my car stereo via the USB and playing a podcast while it was sitting on my black jacket on the passenger seat in the partial sun. After about a half hour, the podcast stopped, so I look down at the phone and it was showing the “emergency call only” screen and that it was too hot. I look at my car’s outside air temp and it was 74F. Not exactly a scorching day. Moved the phone to sit out of the direct sun and it cooled off enough to resume playing.

Just thought I’d mention it here, since I’d never had this happen in the prior 2 years of using my 3G. keep it outa the direct sun on warm days (especially those of you that are actually getting warm days!)
 
Had the same issue yesterday with my iPhone 4. I was streaming music from my phone over Bluetooth to a Bluetooth sound dock when the music stopped. Come to find out my phone overheated. First time this ever happened with any iPhone (I did this a lot with my 3GS). I couldn't use the phone like lathers stated. I turned the phone off and all worked well after that. Big turn off.

Needless to say with all the other issues I have been having, I returned the phone today.
 
this is kind of a no brainer isn't it? leave anything black in the sun and see what happens..

..especially with a lithium battery.. it does that because if the battery reaches over 90 degrees C it becomes unstable and dangerous, its trying to prevent this from happening, a great safety feature if you ask me, why don't you just leave the phone in your pocket before you forget it somewhere?
 
Today my phone got very hot and the call I was making failed 4 times. I've never had a problem with dropped calls with my 3G. I did have screen protectors on front and back- would that inhibit heat dissipation?

I love the iPhone but this is the first time that the complaints about it not being a usable phone have made sense to me. I would really appreciate any info about these heat issues. :eek:
 
I had a 3GS and now I have an iPhone 4 and I haven't seen this screen. My 3GS used to heat up quite a bit but obviously nothing too bad. I did notice my iPhone 4 heat up just a little today when I was txting, installing apps, and on the internet. I'm not saying this problem doesn't exist but it's kind of common sense not to leave electronics in the sun...
 
when this happens to me i just put a cold beer on top of my iphone so it cools down .:cool:

Happened to my friend this weekend as well, he got an exclamation point on the screen that warned him of the high temp.

Hmmm, i guess getting one here in Vegas wouldnt be very smart. It was 109 today:cool:
Dont think ive ever seen anybody here have this problem. Man they really screwed the pooch with this phone.
 
Want to try it yourself?

1. Wait for a sunny afternoon
2. Place your iPhone on a table outside
3. ??????
4. PROFIT!!
 
I haven't had my phone overheat yet. I have noticed it gets considerably hotter than my 3gs did while charging. It was its hottest during the first half of the charge cycle, second half it started to cool down considerable. Once the charge reached 100% it was cool to the touch. This was all inside the house sitting on the arm rest of my couch.

from iPhone4’s page on Apple’s site

Environmental requirements
Operating temperature: 32° to 95° F
(0° to 35° C)
Nonoperating temperature: -4° to 113° F
(-20° to 45° C)
Click to expand...

I would expect that "Environmental" means it should be operable up to 112F ambient air temperature, not the actual device temperature (which it appears apple should have said something like "Nonoperating temperature: below -4F and above 113F)

Yes, I agree. I think I'm using the wrong term for the room because there is zero humidity, it's just a heat room to sweat. Brain dead tonight and can't think of the correct name for the room.

Sauna is the correct term.
 
Just happend to me. Listening to my iPod and using trapster in my car, and. Had it overheat. WTF? My 3GS never did that. Owell.
