My Samsung s21 5g isn't charging properly. it has random shutdowns when charging, though it works perfectly fine when it is not connecting to a charger. I can leave my phone's battery to be dead for a week or two(because it is not charging properly) and after that interval, I'd try charging it and it will charge with slow charging and the random shutdowns to be a minimum and after a couple of days, the problem will persist. I don't know if is the power management chip or what.
