Nike+ FuelBand has a battery life of 1-4 days. If your FuelBand's battery lasts less than 1 day after being fully charged, please call us for troubleshooting assistance.

Make sure your FuelBand has the latest firmware version to maximize your battery life.  The FuelBand's battery life can vary due to many factors, including how frequently you sync your FuelBand with your mobile device.

Nike is continuously working to enhance and extend the FuelBand's battery life.

You can check your battery life at any time by connecting your FuelBand to your USB port. A battery icon will appear on your LED display, either in outline (empty), filled in (full) or partially filled in (partially full).

You can also check your battery life through the Nike+ FuelBand App. Tap the Me icon and then tap the gear-shaped Settings icon in the upper right corner. Tap Device Settings to view your FuelBand's battery level. Your device must be synced with your phone to access the Device Settings screen.

If the FuelBand's battery or memory is running low, you'll be prompted to sync your FuelBand to Nike+.
