How to adjust your device settings to conserve battery life
In summary, any combination of the features listed above can contribute to unexpected battery consumption. If you are in a situation where battery performance becomes critical, we recommend adjusting these features or turning them off when applicable.
- Disable vibrations and tones: Go to System > More Settings > Vibrations/Tones > OFF.
- Adjust backlight settings:
- Go to System > More Settings > Gesture Backlight/Backlight > OFF.
- For PACE 4 and PACE Pro, go to System > More Settings > Display > Brightness > choose Standard.
- Disable Always-On Display: On PACE 4 and PACE Pro, go to System > More Settings > Display > Always On. Toggle this OFF for both standby mode and activity use.
- Disable activity alerts: Go to the intended activity mode on your watch > scroll down to Activity Alerts > OFF.
- Minimize heart rate readings: Reduce the frequency of monitoring heart rate in standby mode by going to System > Sensors > Optical Heart Rate > Daily Heart Rate > select "Every 10 minutes."
- In some cases, you may wish to disable heart rate monitoring entirely. This can be done specifically for activity tracking by going to System > Sensors > Optical Heart Rate > Workout Heart Rate > OFF. Please note, certain fitness metrics like Training Load cannot be calculated without heart rate data present.
- Minimize Bluetooth connections: Turn off your phone's Bluetooth to disable the active connection between your COROS watch and phone. Avoid pairing the watch to any external sensors or accessories when possible.
- Minimize navigation and map usage: If you don't need to follow a route or view the map page, end your current navigation or toggle away from the map page to your regular data pages to conserve battery life.
- Use a more battery-friendly satellite mode: Go to System > More Settings > Satellite Systems to select a new satellite mode.
