I did some other tests about battery and Ox and, after some long tests (3 time every mode for 60-75% of battery), I have those results:
- with Ox day and night 100% of battery 3 days, 9h and 51 minutes;
- with Ox only in the night 5 days, 11h and 48 minutes;
- without Ox 8 days, 9h and 4 minutes.
It's incredible how much buttery need this function for me: is it normal?
If I change watch face with or without seconds indicator and with or without heartbeats there is near no difference about battery drain.
