Severe battery drain after update 12.20

My battery drains rapidly after 12.20! Earlier I loaded at Thursday/Sunday, but now every day!

Down 29% in less than 24h without workout. Yesterdays 30 min rum from 34% to 7%....ok, with music but it used to drain less.

Is there a fix soon or can I somehow downgrade to 11.10 again?

Same here after update of firmware, 100% drain in 9h, HR on, Bluetooth off. I would like to avoid making a warrently claim for a software issue. Is there any way to roll-back one firmware version?

I had the drain right after updating to 12.20 and a reboot would help, but then it'd be back after any activity. Hard reset and it's back to normal.

I am not sure of what's going on with Fenix 6 watches, but I bought my 6X sapphire in May and for 2 months it was wonderful, until Garmin upgraded the F/W, then I had battery drain of 30% in 24 hours idle…

Sometimes it helps to (soft-)reset the watch by holding the upper-left button pressed for approx. 20 seconds until it shuts down. After that power up the watch again and see if it helps.

Yep, hard reset worked for me. I'll give it a charge and see how long it takes to go down 5% or so and report back.
