How long does a smartwatch battery last?

Smartwatch battery life typically ranges from one day to over two weeks per charge. Watches with bright AMOLED displays, apps and always-on screens often last one to three days, while simpler fitness-focused watches commonly last five to fourteen days. Actual life depends on screen settings, GPS, calls and health monitoring.

What drains a smartwatch battery

  • Always-on display and high screen brightness
  • Built-in GPS during outdoor workouts
  • Bluetooth calls and music playback
  • Continuous heart-rate, SpO2 and sleep monitoring
  • Frequent notifications that wake the screen

How to make your battery last longer

  1. Turn off the always-on display or use raise-to-wake.
  2. Lower screen brightness or use auto-brightness.
  3. Reduce continuous health monitoring to periodic checks.
  4. Limit notifications to the apps you need.
  5. Keep the watch software and companion app up to date.

Looking after the battery long term

Lithium-ion batteries last longest when kept away from heat and not left fully drained for long periods. Use the charger supplied with the watch or a compatible replacement.
