Galaxy S7 Edge Restarting Randomly

[AC Question]

Long time listener, first-time poster.

My Galaxy S7 Edge (OS 7.0) continues to restart randomly, and I can't for the life of me figure out why.

I've tried a factory reset, but the problem continues to persist.

Any help is much appreciated in advance.

After it's running (right after a reset), run Settings/Battery. Tap the graph to get to the next graph. Look for sudden drops to zero. If you see any, the battery needs replacement.
