battery discharge faster

They could start fixing the software after all these years.

Why is there no response from Garmin yet? Garmin-Sierra Please give some feedback?

I had the same problem. 5-10 % drain during the night. Turning off HRM and Jabra in-ears under Sensors & Accessories seems to have fixed the issue for me. Maybe the watch is constantly searching for HRM and Jabra after updating to 20.26?? Not a permanent fix, but I will stick to it until Garmin releases a permanent fix...

At least that's encouraging, hope this is common base code and the same can be applied to the FRx55 and FRx65 series too. Hoping for a quick fix/release!

Thanks, disabled my HRM and now it seems to stay at 0.4%/h

Not really a relevant fix for me. Disabling functions to extend battery life is not the answer. I will just charge the watch twice a week instead of once until an update to resolve the issue. 

wristHRM or external Ant?

External ant, i have one configured but i don't use it often. I just turned it off until it is solved

Why isn’t Garmin addressing this? It’s totally unacceptable with this drainage! My long term percentage has gone from 4,15% to 5,05% in just a couple of days. And I’m not even working out because of a cold.
