My phone keeps turning off randomly and wont turn back on, every time i reboot it it just shuts off until I plug it into a charging port. I know the battery is not dead so I don't what the problem is. I did a factory reset and It didn't work either. I have not changed or installed anything with the phone. It is a Galaxy s6 edge, I got it in December 2015 and it was working fine until last week.
