Battery drain after workout since fw 12.20 - reproducible issue

It was some topics re quick accidentally battery drain since firmware update 12.20.

I realised this issue on my f6XPro Solar.

My first observation was when it happened watch is updating watchface every second even for watchface which are not supporting 1hz update, what causes %% of batt every hour.

Now I am pretty sure it can happen after workout. At least it was reproducible three times for three last days.

Conditions:

- outdoor running

- HRM-Tri - ANT+

- inReach Mini connected to watch via ANT+

- BT headphones + Runcast

- No Phone for workout time

When I finish workout (running) my phone and WiFi is available, and typically in seconds watch is connecting to the phone (iPhone).

I realised when I finished running watchfaces continue updating every second all the time. Switch OFF -> ON watch temporarily solve issue, but it can happen next time.

As it was a lot of messages from other guys everything is ok, I am going to experiment with different setups, like doing other activities, exclude one by one connected devices etc etc

I had the battery consumption problem with the 11.75 beta. Reverting to the baseline FW solved the problem, now running 12.20 without an issue.

Today I did my run without inReach, but everything else was in place (HRM-Tri, BT headphones + Runcast, No Phone for workout time) and issue with batt drain after workout didn't happen. Continue experimenting…

I ran I to this issue as well, all using ant+ devices including the inreach mini.

Have you already tried to reinstall the firmware with the webupdater software ? For some, that has solved the problem.

Yes, I've done every type of reset, even deleting device.xml or whatever it's called.

Went on a ski tour, estimates stated 50 hours battery. Ski tour took 5 hours, stopped and saved the workout. 8 hours later my watch died.

Hello, how do you downgrade your Fenix 6 firmware ? Garmin does not allow to download old FW

I spoke of reinstalling the FW.

This has been present on all firmware 12.20+

Yes I've reinstalled, I think it may have to do with ANT+ retrying connections to my inreach and chest HRM. I am testing manuals disabling my devices after my next ski tour.

DuffLevyCGY The „webupdater“ software recognized your watch without any problems? And you used the "reinstall" button?

no, I didn't

hope Garmin should listen and fix in the next update
