I have the watch for 3 weeks
When i received it(new) battery level was 63% and i charged it until 100%
I didn't use electricity so far to charge it again, only sun
I didn't make phone connection, heart rate is off, oximeter is off
Battery level is now at 43% - 36d on smartwatch mode and only 44d on power save.
I was expected arround double battery level on power save mode.
Is this small battery level difference (8days) normal?
