Your tracker's battery life will be determined by your settings and frequency of use. If you're having difficulty with your tracker's battery, see My tracker's battery isn't charging.

  • If you aren’t tracking runs or exercises that use GPS, your fully charged Fitbit Surge™ should last up 7 days as a fitness watch with continuous heart rate monitoring and activity tracking before needing a charge. Your fully charged Surge can track up to 10 hours of activities that use GPS.
  • To maximize battery life:
    • Choose runs or exercises that do not use GPS.
    • Delete or disable one or more alarms. Each active alarm reduces battery life by a small percentage.
    • Keeping the Heart Rate setting on On will reduce battery life. Change the setting to Auto or, for maximum battery life when you don't need a heart rate reading, change the setting to Off.
    • Using Quick View may reduce battery life. To turn Quick View off, go to Settings > Devices on your fitbit.com dashboard.
    • Disable notifications by setting Notifications to Off.
    • Disable music control by setting Bluetooth (Classic) to Off.
    • Shut down your Surge when you aren't using it. Press any button to turn your Surge back on.
    • If you’re syncing with an Android device, in the Fitbit app, turn off the Always Connected option in your tracker settings (in the Fitbit app, tap the tracker tile twice). 
  • Your tracker's battery should last up to 5 days.
  • Increasing the number of alarms you have set on your Fitbit Charge HR™ will decrease your battery life. Each alarm reduces battery life by small percentage.
  • Frequently pressing the button to check your statistics will reduce the battery life.

  • Increasing the number of alarms you have set on your Fitbit Flex™ will decrease your battery life. Each alarm reduces battery life by small percentage.
  • Frequently tapping your Flex to check your goal progress will reduce the battery life.
  • When charging your Flex, be sure to fully seat your tracker into the charger, with the charging contacts fully inserted into the charging cable enclosure.
  • If you’re syncing with an Android device, in the Fitbit app, turn off the Always Connected option in your tracker settings (in the Fitbit app, tap the tracker tile twice). 
  • Your One's battery should last up to two weeks.
  • Increasing the number of alarms you have set on your Fitbit One™ will decrease your battery life. Each alarm reduces battery life by small percentage.

  • If you’re syncing with an Android device, in the Fitbit app, turn off the Always Connected option in your tracker settings (in the Fitbit app, tap the tracker tile twice). 
  • Your Zip's battery should last up to 6 months before needing a replacement.
  • If your Zip is showing a low battery icon within the first month of use, the issue may be resolved by updating your Zip via the instructions above.
  • Frequently tapping the Zip to check your statistics will reduce the battery life.
  • The Zip has a harmless, polysilicone grease on the battery door that lubricates the rubber gasket to ensure a water-tight seal.
  • The Fitbit Zip runs on a replaceable 3V coin battery, CR2025 (pictured below). It can be found wherever batteries are sold.

  • When the battery drops below 25%, a low battery indicator will show on the display of your Zip, as well as on your Fitbit.com dashboard. A flashing battery icon indicates that your Zip is very close to being completely out of battery life, and that it should be replaced very soon. Data could be lost if your Zip is not synced before replacing the battery.
  • When your Zip's battery needs to be replaced, use the battery door tool (pictured below) to open and close the battery door compartment, which is located on the back of the Zip. Your old battery can be recycled.
