Chosen Solution

I have a Samsung galaxy S8 that reboots randomly, it has been factory reset, updated, cache cleared and battery changed as a possible solution but nothing helps. The issue just suddenly came out of nowhere. And is as random as can be. Sometimes it boots up and works for 10-15 min, and other times it just boots up, shows home screen and the reboots again. No particular feeling of overheated when doing it. What could be a maybe cause of the issue?

Probably a bad battery, if the old battery still works can you try that and see if the same problem persists?
