I have been using the watch for couple of days now.
The battery is great at fitness level, GPS on the bike and with working out.
Battery sucks literally when nothing happens. From 20:00 in the evening to 08:00 in the morning so 12h of sleeping it drained 40%.
The battery of this watch is really annoying,.
Today also stopped receiving the notifications. Can not fix it!. (tried resetting / new connection ....)
Yesterday at the end of the workout it just gave me 130 BPM heartrate for 15 minutes strait. No ups or downs. Even wen I stopped it is was showing130bmp... I had to restart the watch for working again.
I like the LCD, and stretch program every hour. It is thin, light and I like the strap.
But I don't know. If I made a right decision to fork out 800 eur. Still have F7 pro.. but when I put it on my wrist now is just looks OLD...

UPDATE:
It appears that the watch has to do at least one cycle of discharge and charge to get it working good for the battery.
