Fenix 5 with 13.40 update high battery drain

Yesterday I received the update 13.40 for my fenix 5 wifi (with sapphire glass). And the battery was discharged by 10% within 12 hours (no GPS usage today). The same problem existed before, but the firmware 12.30 fixed it. And the battery drain was OK about 7-10% within 24 hours.

Does anyone have any idea what to do? I have already restarted the watch, which did not help.
