I have an iPhone 3GS with the latest OS. Starting in September, the phone has started shutting down despite having plenty of battery life. When I try to restart it, it shows a dead battery logo and shuts back off. I have to plug it in and leave it alone for a few minutes until it starts back up. Once it starts back up, the battery shows plenty of charge. At first, it happened when the battery got down to 40-30%. Now it's happening with as much as 90% battery life.

It seems to happen mainly when I'm transferring data via 3G. Emailing, web browsing, etc. But once it shuts off, I have to plug it back in to make it work. No, the phone is not Jailbroken.

Last night I did a full restore, hoping that would solve the problem, but no luck. This is getting to be very frustrating. Any ideas?

Thank you,


iPhone 3GS, iPhone OS 3.1.3
