Help Phone keeps restarting every two minutes on its own.

My Galaxy s6 has been constantly restarting itself as of a day ago. I have powered it down and gone into safe mode. also rebooted it as well. nothing seems to work. It also cant hold any sort of charge.

Sounds like the battery is kaput, and needs replacing.

Agree. Sounds like a battery issue.

If you're opting to replace your S6's battery yourself, just be prepared to work past some hurdles to get to it. Samsung used a lot of adhesives and glues on this model so it'll be a project to not just tear it down but put it back together:
