Need to restart or reset your Fitbit? 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 completely 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 restart your Fitbit by model 

Restarting a Fitbit device often means paying special attention to the charging pins and sensors.

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!

Reset a Fitbit Sense, Versa Series, Ionic, or Charge 3 & 4

  1. Go to the Settings app (gear icon.)
  2. Choose About.
  3. Select Factory Reset or Clear User Data.Factory Reset or Shutdown menu on Fitbit Versa
  4. Confirm with Yes.

Factory reset using the buttons only

If you cannot access the on-screen menus, try resetting using just the button(s) on your Fitbit.

We recommend only following these steps when you cannot access the Settings app on your Fitbit’s screen.

For Fitbit Sense, Versa Lite, 2 and 3 (one button models)

  1. Press and hold the side button until the screen turns off.
  2. After the screen turns off, you should feel a short vibration.
  3. As soon as you feel the vibration, release the side button and then immediately press and hold that button again.
  4. Keeping pressing until the Fitbit logo appears and disappears, and then once again immediately release the button and press and hold it until you feel another vibration.
  5. After you feel that vibration, release the side button, this final vibration indicates you started the factory reset for your Fitbit.

If you run older software on your one-button Versa Series, try these steps

  1. Hold the back button for about 8 seconds. 
  2. Wait for the Fitbit logo to appear, then disappear. Release the button briefly for less than 2 seconds. 
  3. Hold the button again until you feel a second and longer vibration, then release it. This longer vibration indicates the factory reset started.

For Fitbit Versa (original) and Ionic (multiple button models)

  1. Hold all buttons down for around 10 seconds until the Fitbit logo appears, then disappears.
  2. Release the bottom right button only while still pressing and holding the remaining two buttons–wait until you feel a strong vibration, then release all the buttons.

If you followed the process correctly, your Fitbit should show the setup screen. At this point, open the Fitbit app to set up your Fitbit again.

If you don’t release the button(s) at the right time or didn’t follow the exact order of the steps, the Fitbit simply restarts. Try repeating the reset steps.

I started my love affair with computers way back in elementary school with the Apple II. Since then, I've worked with technology in my career as a media educator and videomaker. I have an MFA in media making from Temple University, where I also taught undergrads as an adjunct faculty member. So I know a thing or two about teaching others and creating how-to guides! After a cancer diagnosis, I turned to mobile technology like my Apple Watch to help me monitor my health throughout my chemotherapy treatment and later, to regain my wellness once in remission. I love sharing how to understand and use mobile tech, like smartwatches and phones, as a tool for empowerment to live our best and healthiest lives!


  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!

  4. I have a Versa that that was fully charged and had been synched. Now the screen is black. I followed the instructions for resarting and for resetting, but nothing happens. Any suggestions?

  5. The HR monitor on my versa 2 suddenly stopped working.

    I have restarted it many times and it will work for a few mins and then freeze on a certain HR or just not show anything. The green light isn’t flashing.

    I am nervous to reset my Fitbit. Thoughts? Thank you.

    • Hi Tiffany,

      Sorry to hear that your Versa 2’s heart rate monitor isn’t working. Since you don’t see the green light flashing, it sounds like heart rate tracking might be off. Open the Settings app on your Fitbit and tap heart rate–turn this to On.

      Check out this article for more tips on troubleshooting times when a Fitbit heart rate isn’t showing up: Fitbit heart rate not working or inaccurate? Let’s fix it

  6. My versa 2 has been just fine, I put it on the charger when I got home. Took it off the charger and it will not turn on at all. It has battery life showing on my app, I have pressed and held the button, I’ve tried a new charger, it’s not doing anything… any help would be amazing. I really like it.

    • Hi Bonnie,

      Sorry to hear about your Versa 2. Let’s try this reset method using just the button–this process is dependent on timing, so you may need to repeat it a couple of times to get it right.

      Hold down the side button until the Fitbit logo appears and then disappears. Once it disappears, release the button briefly–make sure this is less than two seconds. Press and hold the button again until you feel another longer vibration, then after the vibration, release the button. This second and longer vibration indicates the Versa 2 started a factory reset.

      Wait for the reset to complete and then go to your app to set up your Versa 2 again to your account.

  7. I am so sad. My versa 2 just stopped working today! The screen went black and I couldn’t get it back on. I put it on the charger and let it get to 100%. Took it off and it seemed to be fine accept that I went outside and I could hardly see the numbers., A short time later it went out again! Charged it again and it will not turn on. Black screen and rebooting isn’t working. Is there any hope? I love this watch so much.

  8. Have a Versa 3 with blank/black screen. I tried everything I knew to do and was going to return it tomorrow – BUT – after reading this thread and discovered a way to reset it I now have a working Versa!!! Thanks RSW

  9. I have a Charge 2 that has a dark screen, previously working fine. The app on my phone looks like it is fully charged. But when it is plugged into the wall, it looks like it needs to be charged.
    I tried the restart, without success. So I have it plugged into the wall outlet for a short time. Can it be overcharged?

  10. my fitbit inspire was synced with another persons phone and now it won’t work just shows a black screen even after charging, how do I go about fixing it so it syncs with my computer and not her phone???

    • Hi Charlotte,

      Since that Fitbit Inspire was linked to someone else’s phone and I assume, their Fitbit account, there are a couple of things that person needs to do:

        Erase the Fitbit device to delete all its personal data. This is done by open the Settings app and tapping Clear User Data.

        Remove the device from their Fitbit account. Open the Fitbit app, tap the Today tab, and then the account picture or icon at the top. Choose the Fitbit Inspire from the list. On Apple devices, then scroll down and tap Remove This Inspire. On Android, tap the trash can.

        Open the phone’s Bluetooth settings and forget the Inspire.

      Once your friend does that, place the Inspire on its charger and wait for it to start charging. Then press and hold the side button until you see a smiley face on the Inspire’s screen.

      If your Inspire is stuck on a black screen, see these tips: Fitbit display screen black and not working or turning on? Let’s fix it!
