My Apple Watch s5 always has a big “usage” - working day it is always about 12 hours stand-by but the “usage” is always about 4 hours. I have AOD on, only a few background refresh on, noise is off. I only have email notifications for VIPs. I have no idea why I always have the almost 4 hours “usage”? I never use any apps on the watch, mostly just look at the watch when there is a notification or to check time. What activities are counted as “usage”?
