Earlier it used to charge at 3-4 hrs. But now it doesnt even charge in whole night abt 8 hrs. Tried hard resetting mah phone, killing few applications. It all started when i plugged usb in a computer and the charging led started flashing on and off. My max charging percentage is abt 50 % only. Need help. I still have waranty bt the service centre is not in my city.
