I have to charge up my phone 8-10 hours before reaching the full battery. Anyone experiencing this kind of problem? PS: I think the battery/charger is not an issue here because I tried to use my battery/charger on my mother’s phone which is the same model as mine ( J700P) and it charges smoothly. And my phone isn’t draining my battery so fast. It stays upto 8-12 hours when I’m using it.
