I purchased a Sandisk Sansa Clip+ FM 4GB a couple of weeks ago, the first time I charged it, it was 100% full (Saying so at settings- info), so I unplugged it, for some reason the next day the battery was empty (maybe I left it on overnight by accident) and I had to recharge it again. When I charge it it only charged up to about 80%.
Even leaving it plugged in for 12+ hours leaves it at 80%.
I tried charging it with a 1Amp micro usb charger from Creative (from an earlier mp3 player) and with a normal wall plug to USB, nothing gets it to 100%.
Am I doing something wrong here?
Thanks in advance.
