I dropped my iphone and it won't turn back on on its own

I dropped my phone and it will only turn on when i plug it into a main charger. When it turns on it says i need to activate it again with itunes, however when i unplug it in order to connect it to my laptop it turns off and won't turn back on until its plugged into the main charger again.

Its called apples poor manufacturing. Its what you get for buying an iphone

What happened is when you dropped it, it unplugged/slightly loosened the battery from the circuit. That's why when you unplug it, it can't hold a charge. Take it into an Apple store and they will professionally remove the back and reconnect the battery

Try to do a manual reset by

1) Reset the iPhone by holding the sleep/wake button at the top right of the device and the home button at the bottom center of the face at the same time.

2)Hold them both until you see the screen go black. In some cases, you may need to keep holding them even after the red power off slider appears. If it does, just keep holding it.

3)Wait until the white Apple logo appears.

4)When this happens, you can let go - the iPhone is rebooting.

Hope it does Help You.
