I installed a simple battery widget and it looks like I'm averaging about 0.25%/hr of drain, including phone notifications, and 30min runs 4-5 days a week using GPS + music.
That's basically fine (great even), as it works out to more than 2 weeks between charges. Even so, I'm always looking for settings to prolong the battery, not that I really need it. So far, I've done things like:
1. Disabled pulse ox (huge drain)
2. Set backlight and vibration settings conservatively
3. Disabled Wifi (does this really help)?
Are there are any other good tips/tricks on maximizing battery life?
In particular, does the music format/quality matter? I have music downloaded from my YT Music account as m4a, but is the watch more efficient with mp3s and lower bitrates?
Anything else that makes a difference? Is it worth messing with GPS settings/disabling constellations?
