I installed the beta the 1st evening. So far it’s working great. A few little UI glitches but battery life is the same (I’ve not noticed any change), sleep works well. Uses approx 25% battery. I have a S4 watch. Hand washing - to answer the queries - the microphone symbol comes on as you start moving your hands in a washing motion. It obviously listens for water. Then it just starts automatically. Make sure it’s switched on in settings. Notifications work fine too. For beta 1 it’s great but as before with past watchOS betas there can be issues ahead. In my eyes beta 3 is always problematic. Let’s see.
great update. Loving the new features. Sleep is great! Plus you get a notification once your watch isfully charged as you hit the shower in the morning to top it back up.
How does the sleep feature work? Do you HAVE to use the automatic schedules? Because some of us don't go to sleep at the same time every night! I tried turning on the sleep mode on the watch but when I do int manually, it does not seem to record sleep. Not sure if this is bug or I am doing something wrong....
