Hi,
Lastly, I found that after full charge I see only 6d. Before (a few weeks ago) I saw 14d.
But it isn't connected to broken battery.
I did test:
08.02.2021 (Monday) - I charged to 100% and I saw 6d.
13.02.2021 (Saturday - 5 day later) I saw 82% and 5d. So battery has good condition. I think that watch with this level of batery should presents about 11d.
I have firmware 13.10.
Do you have any idea or maybe anyone have the same problem?
