iPhone 3G (8gig) battery is fully charged, the phone shuts off when it goes to sleep and will not restart. I've tried holding the power and home button. The phone will restart on it's own when it gets plugged in. But unplug it and when it goes to sleep it shuts off and will not start back up.

Does sound like a bad battery. It might be fully charged, but still have no capacity left.

Would it make sense that the battery worked fine one minute and then lost its capacity the next? Not even enough to turn the phone on?

How do you know it was perfectly fine one minute ago?

If a battery is dead, it will still charge to 100%. However, 100%is measured based on the current battery condition. 100% with a dead battery might mean it will only run a few minutes.

After the phone turns on with a power cord you can unplug the phone and it will work until it goes to sleep.Then it shuts off and will not restart again. If you do not let the phone go to sleep it will run for as long as you can manage to keep it from going to sleep. If you go to settings and set auto lock to never the phone will stay on for as long as you need it. An hour + now.

So it is not the battery. I do not know what I may have said in the OP that would make someone think it was the battery and I don't know why my saying the battery is good was not good enough. But the battery is fine.

I have been walking around with an iPhone in my pocket for three years. I have had all versions, can take them apart and put them back together and know when a battery goes bad.

I have tried al the usual tricks and cannot get the phone to respond. After the last time I tried the reset the apple icon will light up for a few seconds and fade away like it is trying to start. Before that happened I was starting to think it could be as simple as a bad power button.

This may be a stupid suggestion, but have you tried a hard reset/restore?

I've had the same problem! I would set it to sleep and then it just wouldn't open. There was a fix for it a while back, but I managed to get mine replaced.

Is it a jailbroken phone?
