I’m quite impressed with how well this watch holds its battery charge. Battery life has been consistently good.
The "Raise to Wake" function, which lights up the screen when you lift your wrist, could be improved. It isn’t always smooth or reliable. One thing I find frustrating is that the watch face displays the month before the day which is OK for United States but not for Australia. I also contacted the developers regarding an incorrectly spelled capital city in one of the time zones.
