I went to charge my device after a run. It just started vibrating as soon as I connected the cable and won't stop or respond, no matter what I do. It says 18% battery since this happened, so either it will take a long time to run out of battery, or it just isn't updating the display. What can I do?
It just turned off because it ran out of battery. That seems to have fixed it, it is behaving normally now, but I won't know for certain until it has enough charge to really try it out.
