A watch face is on screen all day, so it affects battery life. These tips help on any model.
- Prefer dark backgrounds on AMOLED. Fewer lit pixels means less power.
- Avoid very frequent updates. Designs that animate constantly use more energy than static ones.
- Lower the screen brightness in the watch settings.
- Check always-on settings. Always-on mode is convenient but costs battery.
- Keep the software updated. Updates often improve power usage.
