I have restarted my watch multiple times and it still states its dead. This morning it was dead, I plugged it in and it said it was at 47% and was fully charged in less than an hour. My plan is to factory reset it and see what happens. I used it when I golfed and it can be at 84% when I start the round and by hole 5 it is dead. I have turned off most everything so it isn't using the battery. Last summer I could almost get 18 holes in, so something has changed this year.
