 This is  how you turn-on your phone if your power button is not working.

Method 1

Press and hold the volume up button then connect your charger, wait 10-20 seconds while holding the volume-up button. Once it turned on, the recovery menu will show up then select reboot. Your phone will restart in a normal way. If the volume up is not working try using the volume down.

This method is usually for Samsung galaxy phone. Press both volume up and down button for 10 seconds then plug-in the charger for 5 seconds while still holding the volume buttons. Then unplug the charger and leave the volume button at the same time. OS installation will pop up, cancel it with the down volume button and your phone will restart.
