My first question is this: are you using the same type of charger that came with the phone? Most phones charge at 1 Amp. Tablets, though, often charge at 2 Amps... but have the same microUSB cable.

It's very possible that you could be overcharging the phone if you have a "universal" charger that can also charge tablets. Doing so can fry your phone's internal charging circuitry, and that would mean a new phone. So be very careful in selecting a charger, making sure that its current draw is the same as the phone's.
