Made a call around dinner time with my Kin TwoM. Battery was probably at 80% as I had only made a couple of calls that day and not much else. Few minutes later and the phone wouldn't respond, wouldn't even turn on. Took the battery our for a while and got the phone to restart, but the battery fully discharges and will not charge. I managed to get it back up while plugged into the outlet, but no power on its own. VZW Tech Support is sending me a new battery. Let's hope that's the problem. I had used the phone without a problem for several months.
