How to resolve Apple’s iPhone3GS Overheating and Battery life issues.
Just a week after the release of Apple’s new iPhone, a few owners have complained about the handset’s high temperatures, which in some cases are high enough to start browning the white plastic on the back of the phone.
Notice the battery rectangle burn on the back cover plate.
I had noticed from day one that the iPhone 3GS appeared to have similar heat issues to iPhone 3G: The phone’s back got warm during use. I thought it curious that handset still got warm in many of the same areas as with the 3G. I also noticed that the battery life was drastically reduced.

HOW TO RESOLVED THE OVERHEATING ISSUES IN THE IPHONE 3GS.
Why: Do to the mass production of the iPhone 3GS, several batches had corrupt images (3.0 Firmware).
So when users received the iPhone 3GS the 3.0 Firmware is corrupt. If seams to function normally except for the Overheating and battery issues.
Whats happening is the iPhone 3GS processor is running at 100% when in standby.
Thus causing the phone to overheat and the battery life is shorted drastically.
Solution:
Do not restore from a previous backup, (this backup most likely has the corruption as well).
Download the 3.0 firmware or do your own factory default installation and Restore 3.0 Firmware from iTunes.
Once you complete a factory restore, you will need to reinstall all your apps, and re-sync your music, etc…
This resolved several overheating and battery life issues for several users.

Got something to say?

THX for this solution. I will test it soon as i get my new iPhone 3GS ^^
Nice. Shame the “battery burn’ you refer to is actually a case of color transfer from 3rd party cases, which can be cleaned up through the simple application of rubbing alcohol.

Great solution, i have fixed my iphone 3gs overheating issue. Thank you!!!
Regardless of what causes the new Iphone 3GS back cover discoloration the point is that “SEVERAL NEW IPHONES 3GS FEEL HOT, VERY HOT WHEN CHARGING OR USING RIGHT OUT OF THE BOX”
reinstalling the 3.0 firmware works and resolves the corrupt images during the mass production of the phone.
Would installing 3.0.1 work?
Yes I believe that installing 3.01 could aslo work for the image restore as well.
