Estimated battery life without BT/Heart sensors?

Garmin indicates 12 / 14 days in smartwatch mode for 255/255s. Anyone can check what the estimate is on the watch with BT turned off and all sensors?

With Fenix series it typically doubles with everything turned off except for turning on saver. So I wonder if that gain is similar on the 255 series?

12 to 14 days is completely unrealistic unless you never actually do anything with the watch.

For reasonably active people who use GPS 6 to 7 days for the 255 is more realistic - I have had my watch 2 weeks and need to recharge for the 3rd time very soon.

But that is my question how long it lasts not doing anything, just watch mode. Garmin also didn't spec battery saver mode for some reason.

Disabling wrist HR takes the estimate from 3 days to 4 days

Disabling phone connection takes the estimate from 3 days to 4 days

Disabling wrist HR and phone connection takes the estimate from 3 days to 5 days.

This is with 21% battery remaining. Forerunner 255 Music
