So I was watching youtube and all of a sudden my phone shuts off,I try to turn it back on but it keep boot loading I tried soft reseting and all but nothing works.When I unplug my phone from my charger the phone wont work at all

I know these models tend to have power management IC issues but you might want to try a new battery first seeing as it won’t even attempt to power on unless it’s on the charger.
