Today morning my Garmin Fenix 7 Solar battery was draining 4% per hour. I had not made any changes in the watch, the battery was just draining. Reset with light button didn't help. Finally I installed the latest 9.33 update, and now I'm back in under 0,2% drain per hour.
Now I'm wondering how a sudden battery drain is possible, and what made it happen? I had sleep mode turned on, but I don't know if the watchface changed to "sleep mode". When I waked up, the watchface was normal, but sleep tracking didn't stop before I stopped it manually.
Any suggestions why this battery drain happened?
