I was charging it with a power bank and it worked just fine until it suddenly turned off by itself then i unplugged the power bank and it started to turned on by itself but its just like "samsung s4" then it turned black then it turned on again after several seconds "samsung s4" and so on. Ive tried to take off the battery but its still the same. It doesnt even turned off at all. Ive tried to charge it again and it gives me the loadin sign but wont charge and the led light doesnt turn red. So my plan is to drain the battery until 0% then i charge it. Is it wise? The battery does not swell. Its normal and the temp of my s4 is normal not hot. Please help
