So I overheated my iPhone 4

On Saturday, I was having lunch outside and had my phone sitting on the table, and it overheated. I got a screen saying my phones temperature was too hot and only emergency calls were allowed. I know it might have been dumb of me, but didn't think it sitting on a table in 80 degrees during lunch would be that big of an issue, haha. After I put it in my pocket, it cooled down and works fine. All is well.

My question is, this overheating doesn't trip any sensors in the phone that might void the warranty, right? Like I said, everything works fine and no damage was done, but I'm concerned my warranty may have gotten voided or something by going into "temperature control mode."

Thanks!
 
This is the first iPhone I've had that I recall ever getting hot....perhaps we have another issue on our hands?
 
Happened to my friend this weekend as well, he got an exclamation point on the screen that warned him of the high temp.
 
There have been a few temperature related posts here. It is just a warning message and the phone protects itself by shutting some features off to do its part in lowering the temperature.

That won't void your warranty as you did the right thing and kept it cool, unless you ignored the message and the phone started to have more problems as a result of that....

you cant ignore the warning
 
I've gotten this message on all my iphones before. Usually when I accidently leave in the car for a few hours.
 
i laid on my chase lounge today in 94 degree wether. i had my headphones in and was listening to some tunes, i put my white t-shirt over it (it was directly in the sun) and in a half hour it wasn't really that hot at all.
 
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.
 
It happened to me today too...
I was at the barber shop waiting for my turn. Surfing the net on 3g (which I normally turn off). All of a sudden it got really warm. I turned it off right away and put it away in my pocket (where it remained noticably warm for several more minutes). I haven't had any other issues such as attenuation, discoloration or proximity sensor issues but did recall maybe reading something in these forums earlier in the week about overheating.
 
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.

Yikes that doesn't seem smart. The humidity can't be good for it either..

Really? The phone comes with a feature that will prevent you from leaving it in the sun? Wow. That's some amazing technology!

you can't use the phone after it gets too hot and at that point it shuts down pretty much completely so it would be hard to damage it severly unless it was like 200 out

190-210!!! I'm amazed the iPhone survived that...

Taking any piece of electronic equipment into a Sauna is not smart. Blackberry puts a detector under the battery that goes red if exposed to moisture and it voids the warranty.

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.

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.
