When ever my black berry 9700 battery is at 50 percent or 40 percent, it use to show me battery drained. And whenever I plug it to charge, it only show me steady red light which will go off after some seconds. And it won't charge untill I charge the battery with external charger. After charging it with external charger, the battery will continue to charge with usb or wall charger when the phone is on. I don't know wether this is a hard ware or software problem, pls help me out thanks.

Try a new battery but make sure it's a Blackberry OEM battery not a knockoff.
