Yesterday my ticwatch had started to discharge very qickly. And so does now.
Usually I have about 30% by the evening, but now I have 40% by the noon.
I had not installed any new app on the watch or on the phone,
I had not installed any updates on the the watch or on the phone.
I don't use any watchfaces which detect my heartbeat.
Wi-fi set off, all the gestures and voice functuons set off (except Tilt to light up), ambient mode turned on, brightness set to 1 and screen backlight set to 10 sec.
The watch simply SUDDENLY start dicharge very quikly.
And yep, I did factory reset on the watch - didn't help.
By the way, yesterday a lot of energy was drained by "dialer" on the watch. But I didn't use dialer at all. Unforunately I forgot to take a screenshot.
Here is some screenshots of today.
