@Stefan-T.
I was experiencing this after I first got the watch. I did a soft reset. In subsequent uses, 10% of daily usage
Exercise, navigation off.
Wake from wrist on
AOD off.
Screen brightness medium.
Notifications on (I get a lot of notifications during the day)
24/7 wrist heart rate monitoring on
I sync 3 times a day.
I update the altimeter from GPS twice a day (just a habit )
Blood oxygen on.
Alarm on every morning at 7 AM.
Sleep tracking on.
Sunrise and sunset alarms on.
Media controls on when I listen to music through headphones.
Sometimes I use the flashlight (for about 10 seconds. For advertising )
Things that come to mind.
