Stored data consists of steps, distance, calories burned, floors, active minutes, heart
rate, exercise, sleep, and stationary vs. active hours. Charge 2 can store a maximum
of 10 hours of exercise data. This means that if you exercise for more than 10 hours
and don’t sync your tracker, your exercise history will not include everything. We
recommend syncing your tracker at least once a day.
Display
