So I normally use the HTC wall charger but left it at home and grabbed a Plantronics wall charger that came w/ my bluetooth. It's micro usb and everything, 5.0v output, etc. I plug it in, and the battery goes from red to green w/ a lightning bolt, but the green is moving to simulate charging. and a pop-up keeps telling me i'm at 12%. So, will other chargers not work on this thing?
