Well, you’re gonna want to try a new battery first. Also test if the charging port is good. It could’ve been a software update, that messed up your phone. You can do a restore, you’ll lose your data. I’m learning about something called ODIN, that unbricks android devices. Also a real common thing with galaxies. The power button fails, and if it doesn’t turn off and on by itself, it just stays off. The button needs to be microsoldered on. Not the most difficult, but not easy either
