Have you tried restarting it? It does no harm and can sort out all sorts of issues:

1. Plug the charging cable into the USB port on your computer or any UL-certified USB wall charger.
2. Clip the other end of the charging cable to the port on the back of the tracker. The pins on the charging cable must lock securely with the port.
3. Make sure the button on your tracker is aligned with the button opening on the charging cable. You’ll know the connection is secure when the tracker vibrates and you see a battery icon on your tracker’s display.
4. Press and hold the button to restart your tracker:
   1. Charge 2—press and hold the button on your tracker for 4 seconds. When you see the Fitbit logo and the tracker vibrates, the tracker restarted.
   2. Charge 3 & Charge 4—press and hold the button on your tracker for 8 seconds. Release the button. When you see a smile icon and the tracker vibrates, the tracker restarted.
