How to fix my phone from restarting by itself?

[AC Question]

Currently, I have the Samsung Galaxy s7 edge but it keeps restarting after 10 to 12 minutes of use. Before it restarts it vibrates once, pause, ando then vibrates twice. I have cleared my cache partition but this problem remains. I would try to remove the battery but I'm pretty sure the back does not come off on the edge. Can someone help me make it stop?

A bad battery? A poor battery connection? An SD card problem?
