I even fully reset my watch but it's about 2% Darin per hour.
Are you using a custom watch face? Does the drain return to normal if you switch to a standard watch face (as a test?)
Thanks a lot for your kind reply. I don't have any app, Watchface or widget installed.
The watch is just factory stock reset and using one of the preloaded watch faces.
Update to 4.70 seems to have fixed my battery drain. I am down to about 0.7% per hour now!
