Garmin Vivoactive 3 battery drain

Garmin Vivoactive 3 battery drain

Hi guys, I see that many users complain about fast battery discharge from 100% to 0% in a day or even less. Reportedly the problem appeared after the firmware update 6.2 and with the FW 7.54 it is still there. All sorts of resets and reboots do not solve it. All IQ apps removed. Garmin support can only offer a substitution for a refurbished item fro 99 USD, which does not look like a solution. Any ideas how to help? Thanks.
