My iPhone turns on and off!

Hi there.

My iPhone 4S (model A1387) will not boot into iOS.

When the power cable is connected, the iPhone boots up initially and displays the apple logo for ~3.5 seconds. Then it goes to a blank screen for another ~2 seconds and the process repeats (indefinitely it seems - at least at this point).

When the power cable is removed, the screen displays the apple logo for 3 seconds

then it goes blank screen for another ~2 seconds and the process repeats

Please help me ... Tel me whats the issues , should I change my battery?

Try another battery. It's most likely a bad battery.

I was going to say doing a restore or update is pointless with that symptom.. As it's 100% hardware issue.
