Battery Life by Usage

  • Light Use: Up to 48 hours (basic notifications, occasional glances)
  • Normal Use: 36-40 hours (notifications, health tracking, apps)
  • Heavy Use: 24-30 hours (always-on display, GPS, frequent apps)
  • Continuous GPS: 8-12 hours

What Drains Battery Fastest

Features that use the most power:

  • Always-on display enabled
  • Continuous GPS tracking
  • LTE connectivity without phone nearby
  • High screen brightness
  • Frequent app usage and notifications

Rotating Bezel Advantage

The physical rotating bezel uses no battery power. Navigating with the bezel instead of touch actually helps conserve battery by reducing screen wake-ups.


Extend Battery Life

Tips to get more from each charge:

  • Disable Always-On Display: Adds 15-25% battery life
  • Lower Brightness: Use auto-brightness or 50-70%
  • Use Bezel Navigation: Reduces screen touches
  • Reduce Notifications: Filter to essential apps
  • Enable Power Saving Mode: Limits features but extends battery
