I suggest you force shutdown the phone(power button+vol up until the phone vibrates 3 times).Connect to wall socket and let it charge.Turn it on.
Wall socket charger that comes with the phone has a 1 Amp+ rating and it charges faster than the USB cable connected to computer's USB port.
Of course,it charges faster.
You should only connect with the adapter that comes with the phone and the USB,nothing else.
And you cannot get to a socket?I do it almost always,charge to a socket.
