Would be good if Samsung could add a " Double tap to wake " option on the watches to save unintentional waking of the display - especially for at night when you are sleeping - ( as per my other post I seem to be accidentally touching the display with my other arm quite a lot and using a significant amount of battery overnight )
I do turn on bedtime mode before I go to sleep. I do not sync bedtime mode with my phone. Definitely try it, prevents any accidental touches at night and saves battery. Then you can leave tap to wake on during the day.
