Shutoff from heat?

[Joshakeit]

At the moment my daily driver is a Samsung galaxy s8 and as of late December and early January it has been shutting off, not the way you'd like, it doesn't say Samsung or anything just kills itself even though it has +50% and when I try to reboot it, it refuses to boot and I narrowed the issue down to heat.. when it barely get warm.. like noticeable heat then it kills itself like the heat detector is messed up.. what can I do to solve this.. if i cant find a solution I'm changing phones. Thanks, SquiddyJ

Then it's a hardware defect. If it's still under warranty you should RMA it.

more like a dead battery to me. can it stay on while in download / recovery mode?
