After 48 straight hours Watch is at 29%. Could probably stretch it to 72 hours for a full three days if I tried. Regardless, it's impressed me.
Settings
- I use a boring watch face. Two tone. Nothing fancy.
- Screen is not always on. I look at my watch maybe 10 total minutes an hour, I don't need it on 24/7.
- Cellular/GPS service on.
- Brightness & sound on default. Vibration on high.
Use
- Emailed/Texted about 20-25 over the weekend. My weekdays will have significant more use.
- Streamed music for an hour.
- Took four calls. Average call time was 4-6 minutes using Watch speaker.
- Checked ESPN app for sports scores.
- Used the flashlight app several times.
- Downloaded a few new apps: WatchTube, Lens, etc.
- Use Tesla app to control my Tesla 2-3 times per day.
- Sleep tracking.
I used to wear the Series 6 but never at night. Charged it every night before bed. With the longer battery life I decided to wear it throughout the night. Sleep tracking is interesting to view. I can easily see this watch lasting three full days of 72 hours if i skipped the music, flashlight, and messing around with the new apps. Three days is what I was aiming for, as often I'll head out of town for the weekend. Even if you don't need the additional ruggedness of the Ultra, the battery life itself makes it attractive. I also road bike 100 mile century events, but my last one was two weekends ago. Didn't have a chance to test it.
