I have been using the watch for three days now; below is my first impression:
The watch was fully charged and kept off for one day; the battery was 75% when turned on. Weirdly, it will drain even if it is off.
First day of use, always on display off, adaptive brightness active, the battery lasts for 8 hours.
Today, I took the watch from the charger, which was 100% at 7:30 am; now it is 11:00 am, and the battery is 83%. The clock shows that the battery's remaining life is 10:33 hours.
