smartwatch battery drain in AOD

Version 7.3.3 and 7.3.4, device ticwatch E
With AOD enable, and set a simple watch face with only black bg and a grey clock, the battery during 3-4 hours, instead before the update the duration was about 13-14 hours (depending the utilization).
If i set Google Fit as watchface and enable the AOD there's no problem with battery duration.
On Reddit I've add more information and test (logcat too)
