iPhone won't turn back on
So my mom had gotten this iPhone from a friend and it was unresponsive. So I replaced the battery and it turned on and charged up just fine. I shut it off and when I tried to turn it back on the next day it was unresponsive again. I have no idea what's going on. Please help.

Where did you get the battery from and have you tried plugging it into a computer?
