Some features use more battery than other:
- Screen on duration
If you set something > default, it will obviously use more battery to keep the screen on
- Ambient mode
The “Eco” Ambient mode is the default one, and will be very battery efficient. No additional batteryusage.
The other ones use a bit more of battery, by displaying and updating data even in ambient mode(and colors for full).
Basically, eco < b&w < full
Also, the more you hide content in ambient mode, the more you will save battery. You have access to a few options to hide the unnecessary content 🙂
- Heart rate data
The heart rate sensor uses a lot of battery. I would recommend to use it only during a workout or short sessions.
If it can help you to get a good usage 🙂
