So I ran a half marathon this morning and forgot to get a full charge before I started the race. The Band lasted until just before mile 10 which wasn't too bad considering. My issue after charging the Band back up is that the Health app will not display my step count or calorie burn for the day although my Band is still tracking. Also, in the activity feed in the app, it shows my run up to the point where the battery died but it has no GPS or map data although it was turned on. Anyone else having issues like this?
