Decided how far I could go on a charge with my AW Series 5. Saturday morning 7am put the watch on, 100%. It just died Sunday afternoon, some time after 3:15pm. That was over 32 hours. In fairness, I didn't track any workouts this weekend. It was something around 4hrs usage and 32 hours standby, last time I checked before it died. Always on display ON, noise monitoring OFF.
