I recently bought a phone Pantech Crux from Pantech which was working well for the first few days and then it suddenly started showing it signs. My phones battery gets down even when I have not used it much. Apart from this the music intensity has also dipped within few days, the phone get hanged at times. but I cannot understand why all this happening with my phone. Can u suggest me what could be the problem or what i can do increase my battery backup so that it work for a longer period.
