Need to restart or reset your Fitbit device? Learn the steps

Usually, our Fitbit devices work without any problems, but occasionally they start acting in unusual ways, from not regularly syncing to not responding.

Frequently reported issues with Fitbits include things like:

  • Not turning on after fully charging
  • Fitbit app stuck in looking for the device
  • Bluetooth connection not working between Fitbit and phone
  • Slow or sluggish performance
  • Won’t respond to button presses, taps, or swipes on-screen
  • Not tracking activity, like steps and other fitness data
  • Won’t sync or can’t successfully complete a sync

If your Fitbit shows these types of signs and symptoms, one of the best (and simple) fixes around for your Fitbit device is a restart and/or a reset!

Restart or reset your Fitbit? What’s the difference?

Although some use these terms interchangeably, there is a significant difference:

  • Restarting your Fitbit turns it off and on without deleting any activity data.
  • Resetting your Fitbit wipes all the data from your device and turns it off and back on. This procedure is also called a factory reset

While it’s usually easy to restart your Fitbit, resetting involves more steps.

How to reset your Fitbit by model

We don’t recommend resetting your Fitbit unless the restart didn’t work, OR you intend to give away or sell your Fitbit to someone else.

That’s because resetting your Fitbit also resets all your personal data–it’s like starting with a fresh & new Fitbit.

In cases where your Fitbit continues to perform badly, refuses to sync data, or continues not to be recognized by your phone, computer, etc., even after a restart, we do recommend you reset your Fitbit.

But with the knowledge that your data is removed and following a factory reset, you must set up your Fitbit again.

When you perform a factory reset, the reset deletes all device data, including any data that has not synced to your Fitbit app and account.

This includes things like your personalized settings, alarms, goals, and notifications.

Resetting your Fitbit DOES NOT remove your Fitbit account!

  1. I have a FitBit One which I had to restart. For the first time when turning it is showing the time when it died due to low battery together with the number of steps etc that were on the screen when it went off.
    How do I reset it to the correct time etc?

    • Hi Lorna,

      Charge it to 100% and then sync it with the Fitbit app or Fitbit Connect. That should do the trick.

      If not, use either the Fitbit app or your Fitbit online account dashboard and navigate to the Advanced Settings (also called App Settings) and make changes to your time there.

  2. I have a versa it has an X with a circle around it with the message data not cleared. sync and try again. i have not clue what to do . Can someone help me

    • Hi Kitty,

      This usually indicates a sync problem.

      Try closing the Fitbit app and then restarting your mobile phone/device that you normally sync your Fitbit with.

      If that doesn’t help, visit your mobile’s Bluetooth settings and choose to forget the Versa from Bluetooth. Then, re-connect to Bluetooth and try to sync your Versa.

      When problems persist, even after these steps, the next option is to press and hold the back button (or for Versa original model, the back and bottom buttons), until you see the Fitbit logo on the screen–once you see the logo, let go of the buttons.

  3. I got a Fitbit inspire for XMAS.

    Set it up December 26th everything worked. Took it off shortly after.

    Put it on again on December 27th.

    No heart rate readings whatsoever and no flashing lights underneath.

    I have rebooted/reset/done everything.

    Heart rate notifications setting ON device. Wore it all day 27th. No HR record whatsoever. No light under watch at any stage. Totally dead.

    I think this must be a faulty device. Will be returning it. Too much hassle with a brand new device. It should not be troubleshooting so soon. Disappointing

    • Hi Wendy,

      We are really sorry that your new Christmas gifted Fitbit Inspire isn’t working like it should.

      One thing to check is that your Fitbit is set to on-wrist and not on-clip.

      On-clip disables heart rate tracking automatically since it cannot collect any data.

        On the Inspire, press and hold both of the buttons to access its Quick Settings menu

        Select the On Wrist or On Clip setting

        Enable On Wrist

      Another option you could try is to remove the Fitbit Inspire from your account, then delete the app on your mobile device. Once deleted, restart your mobile device and then reinstall the Fitbit app.

      Finally, add your Fitbit Inspire back to your account.

      Also, make sure both your Fitbit Inspire and Fitbit app are up to date with the latest versions.

    • Hi Charles,

      Try resetting your Fitbit Charge 3. First, sync your charge to save any data to your account.

      Then, on your Charge 3, go to Settings > About > and tap Clear User Data. Finally, reconnect your Charge 3 to the Fitbit app.

      If the time/date is still incorrect, follow the steps in this article: Fitbit didn’t update the time? Let’s fix it!
