Spark - Sports Connect online shows almost fully charged, but watch warns little charged
Getting ready to head out and charged my Spark via computer from 8 o'clock position to 11:55, i.e., virtually fully charged, if the yellow dot is to be believed. But when I started the watch for a run, it gave a charge warning buzzer/screen and the watch shows little charged up top. First time I've seen this. What might be going on?
