IphUser, all that you describe seems to point to one thing. The battery. I would go ahead and definitely replace it again, this time with a quality battery from a reliable vendor. Also, make sure that you have the right battery, remember that they are not interchangeable with the 3G. It will shut down when plugged into your computer because the battery does not hold a charge. The USB port only supplies 500maH which is not enough to maintain the iPhone, and of course you can not sync or restore it on an AC adapter. At this point you really have nothing to lose but a lot to gain by at least giving it another try. Also, make sure that your USB cable is working properly and that your dock connector is clean, free of debris, and does not have any bend broken or corroded pins. Here is the guide and the battery is available here. Hope this helps, good luck.
I have exactly the same problem with a Iphone 4S that runs on IOS 7.0.4 i have already tried everything, now i am about to heat up the battery connector on the motherboard, i hope that will help. If not i am gonna sell it and buy a brand new one. there is one thing, i did put my phone away for like a day, then i rebooted it and its worked for 1 or 1 and a half hours and then it turned off again. So like everyone else it isn’t the battery, the battery works fine on other Iphone 4S'
Hi everybody. I have the same exactly issue happening with my 3GS. It was everything ok with it but i stopped using it for like 1 month and now it is behaving like the problem described here in this thread. Has anyone found anything to solve that? Thanks

Hello Jaspreet singh, Like many of us the problem isn’t the battery. But if your phone is getting really hot, you should try to replace the battery. Maybe it has a thump on it and then you are sure that is the problem. Anyway just try replaceing the battery, there are enough videos on youtube showing how to do it. Goodluck.
Yes, I have a iPhone 3GS, 16GB, with the same issues. That is will only stay on if you do not touch it, but if you use it, it shuts off. It Only comes back on and stays on when plugged. I have taken it to the Apple Store. The genius bar tech stated that it looks like it has never been tampered with. Suggested to give a little credit for it because it is not yet vintage. I have taken it to Tech&Soup to repair. They have replaced the battery and motherboard with brand new ones to find out that these replacements where useless. I have also tried keeping the iPhone plugged for 14 hours straight. This did not help.
