Random crash and reboot when warm.

Currently, my iphone 3gs will shut down and reboot almost daily under moderate to heavy use (games, photo sharing and editing), but good under light work (can read an ebook for hours).

It's 2 years old and has been dropped 5 times in the first 6 months. Symptoms started about 6 months ago, but less frequently so they don't seem related to the drops.

The first crash happened while on the car charger with a nav app, then a few weeks later with a different nav app, had to restore through itune and got error 1603 so I thought it was the gps.

Then it happened with music with the car charger, and one time it crashed the second I unhooked it from the car, so I thought the charger was bad.

Eventually it started happening while playing games. Even under the sun, it can crash. Then it would go into a constant reboot loop showing the apple logo, and sometimes the 'plug into itunes'. It went through a few restores via itunes, sometimes an error and sometimes not, until recently it would sometimes crash halfway through a restore. Now, I risk a crash if it's in my pocket too long.

It took of while of troubleshooting, but I found that if I put it in the fridge for a short time to cool it down, it will turn on in about a minute, even if if I get the itunes logo. I've also tried using it under heavy load with an ice pack on the back of it and it seems to work fine, and would restore perfectly while sitting on the ice pack. I'm sure it's heat related. My friends have never heard someone say, "oops, almost forgot my phone in your fridge" ;)

I took it apart and it was loaded full of 2 years worth of pocket lint. I blew it out with canned air and all the contacts look fine, went back together and still works, but no different.

Can this be a battery or cpu problem?

Appreciate any help.

Thanks for the suggestion. I was hoping it's the battery. I think can get one from a dealer in my area. For $20, it's worth a shot. I'll post the results when I get it done.

Its interesting , i cant find an answer to this anywhere on the net. At least the hardware side of it. Everyone points to software fixes and for some, battery replacements. Well im about to go through my4th battery , have restored numerous times, starting from scratch ,running without apps and then with and my problem still remains , shutdowns at under 60% with the sim in,...sim out no problem. Seems a lot of people are having similar problems .

I guess with a complicated little device like this there could be many reasons for the same problem.

it's my understanding that one of the sensors on the iphone battery is for temperature...therefore if your poor battery is old, tired and being overworked to play games it maybe getting hot and triggering the temp sensor to crash the phone. Idea no. 1 would to be invest in a new battery (this one is 2years old and that's about right for a change) just remember to power the phone off properly to prevent damage to components when you are swapping the battery

I changed the battery, but not any different. It still crashes when I over-exert it. Oh well, may as well upgrade in a few months. Thanks anyway.

sounds like power management then...

Have you tried deleting some of the apps from your phone to free up some memory? if you click home x3 very quickly it should take you to the apps that are running in the background..try turning them off. Might be the poor phone is trying to do too much all at once.

Thanks for the reply. I am constantly doing this throughout the day and only make sure at least 2-3 apps are open at any given time. Like the OP said I have to keep it cool or put it in the fridge to get it working 'properly' again. Otherwise hot summer days are a big issue for me. Any ideas?
