Hi, lately my battery is giving me a hard time charging. Sometimes when I plug it in when the phone is on it will say something like charging timed out, battery is to hot or to cold. Then sometimes when the phone is off and I try to charge it it will say battery disconnected and vibrate til you unplug it. I've had this Samsung Intrecept for about 2 yrs now. Why is this phone doing this...it's very frustrating? Thanks
