Ran phone battery down to dead.... Plugged into wall charger....momentarily showed 5% charge....then showed 0% charge...then off..... Now with it plugged into an outlet I get a few seconds of the MOTO symbol but thats it...and no green light on top. Plugged into the USB it seems to charge fine... Anyone else seen this?? Also, how are you guys seeing the percentage level of the battery?? THanks!
