Learn how to reboot or factory reset your Fitbit tracker.
Your Fitbit may act most of the time reliably, but you’ll need to know how to unpair and reset it if it starts malfunctioning.
Whether you have a Charge 6, Versa 4, Sense 2, or Inspire 3, it’s best to start with a clean slate if your Fitbit fails to respond, won’t track or sync, or you want to gift it to a friend.
There are also occasions when you may want to give your Fitbit tracker or smartwatch a full factory reset or erase your data.
In this guide, we’ve detailed exactly how to restart every Fitbit device. Jump to your specific device or read the steps below to unpair or factory reset any Fitbit.
How to reset your Fitbit
Further down this page, we’ll explain how to perform a soft reset for each Fitbit, which means giving your tracker a quick restart.
However, sometimes, you need more than that. Sometimes, you’ll want to clear your user data entirely.
Not every Fitbit lets you perform a factory reset from the device itself, but there are ways to start each one with a blank slate again.
How to perform a Fitbit factory reset (general method)
- Open the ‘Settings’ menu on your Fitbit device.
- Once in the ‘Settings’ section, look for the ‘About,’ ‘Device info,’ or similar tab and tap it.
- From here, scroll to the section labeled ‘Factory Reset’ or ‘Clear User Data.’
- Confirm the reset when prompted by hitting ‘Reset’ or ‘Confirm.’
Unpairing Fitbit: Step-by-step
Unpairing a Fitbit can not only free your account to pair with a new device but also make it free to link to another Fitbit account. So, if you get a new Fitbit device and want to gift your old one to someone else, follow these steps:
- Open the Fitbit app and tap your profile icon in the top left corner.
- Select your Fitbit device from the list.
- Scroll down and choose ‘Remove device’ or ‘Delete device,’ depending on your model.
- Confirm the removal. You may want to ensure all your data is synced, as this will clear everything.
If you’re having issues with your Fitbit, unpairing and going through the setup process can also help resolve this.
‘My Fitbit has been reset but won’t pair to a different smartphone’
Top tip: After using the Fitbit app to remove the device, you may have trouble re-pairing it with a different smartphone.
That’s because sometimes unpairing from the Fitbit app doesn’t “forget” the connection between your phone’s Bluetooth and the Fitbit.
Head to the phone’s Bluetooth menu, see if the Fitbit is still listed, and choose “Forget this device”. You should then be ready to pair immediately. If it still doesn’t work, restart both your phone and Fitbit, then repeat the pairing process.
How to restart Fitbit Versa 2-4 and Fitbit Sense 1/2
Rebooting the Versa 4, Versa 3, Versa 2, Versa Lite, Sense, Sense 2, Ionic, and Blaze is perhaps the easiest way to restart a Fitbit device.
- Versa 2, Versa 3, Sense (1st gen), Versa Lite:
Press and hold the side button for about 10 seconds until the Fitbit logo appears, then release. - Versa 4 and Sense 2:
Press and hold the side (capacitive) button area until the logo appears, then release. - Ionic and Blaze:
Press and hold the left and bottom-right buttons together until the Fitbit logo appears, then release. - When the Fitbit logo appears, release the buttons or the capacitive area.
- Once complete, you should be prompted to open the Fitbit app and set up your device.
Remember that restarting your Fitbit this way will not erase your data or require a new setup. If you’re prompted to reconnect the device, it’s probably been factory reset instead.
Reset the Fitbit Charge 6, Charge 5, or Luxe
If your Fitbit Charge 5 or Charge 6 isn’t responsive, you can hard reset it by plugging it in to charge using the supplied cable.
- Charge 5 and Charge 6:
Connect the device to its charging cable.
Press the button on the flat end of the charger three times within 8 seconds, pausing briefly between each press.
The Fitbit logo should appear while the device restarts. - Luxe:
Connect the device to the charging cable, then follow on-screen or device-specific restart steps (the charger button method is not supported).
Alternatively, go to Settings > Device Info > Clear User Data to factory reset your Charge 5, Charge 6, or Luxe, and wipe all data.
Reset the Fitbit Charge 4/3/2
If you’re having trouble syncing, tracking, or connecting to these older versions of the Fitbit Charge, it’s time to restart the tracker.
To do so from the tracker (applies to Charge 3 and Charge 4), swipe from the clock face to Settings > About > Reboot Device.
However, if the tracker isn’t responding (all models), follow these instructions:
- Plug the charging cable into a USB port and connect the other end to the back of the tracker.
- Make sure the tracker’s button is aligned with the button opening on the charging cable. The tracker will vibrate, and you will see a battery icon appear on the display.
- Hold the button to restart your tracker:
- For Charge 2, press and hold the tracker’s button for 4 seconds. When you see the Fitbit logo and the tracker vibrates, it’s restarting.
- For Charge 3, press and hold the button on your tracker for eight seconds. When you see a smile icon and the tracker vibrates, the tracker has restarted.
Reset the Fitbit Inspire 2, Inspire, and Inspire HR
Whether you have the Inspire HR, the non-HR version, or the Inspire 2, if you find you can’t sync your tracker or you’re having issues with tracking, here’s how you can restart it:
- Plug the charging cable into a USB port, then connect the other end to the back of the Inspire tracker, ensuring the pins are locked into place.
- From there, press and hold the device’s left button for 10 seconds.
- On older Inspire models, a smiley face appears, and the tracker vibrates, to show it’s restarting. The newer Inspire will show the Fitbit logo.
Again, like the other restarts, this reboots but doesn’t perform a factory reset on your device.
Reset the Fitbit Ionic
Resetting the now-retired Ionic is performed the same way as the Versa, and is another easy way to restart a device from Fitbit.
- Press the left and bottom buttons until you see the Fitbit logo on the screen. This should take roughly 10 seconds.
- When the Fitbit logo appears, release the buttons.
This process restarts your device, but does not wipe out all your data, and does not require a new setup.
Reset the Fitbit Alta HR
Unfortunately, you can’t perform a factory reset on the Alta or HR. Instead, you will have to restart your device.
- Plug the charging cable into a USB port and connect the other end to the back of the tracker, making sure the pins on the cable are securely locked.
- You’ll know the connection is secure when you see a battery icon on the tracker’s display. The tracker will then begin charging.
- Press the button on your charging cable three times, briefly pausing between presses. When the Fitbit logo appears, the tracker will vibrate to indicate it’s restarting.
Reset the Fitbit Ace LTE or Fitbit Ace 3
Fitbit’s newer fitness trackers for kids are reset differently from the original versions.
- For Fitbit Ace LTE:
Ensure the watch is turned on, then press the top button or swipe down to access ‘Settings.’
Go to ‘System’ and then ‘Disconnect & reset.’
If a new user will use the watch, enable ‘Erase eSIM.’
Tap the check mark to confirm. - For Fitbit Ace 3:
This device doesn’t support an on-device factory reset.
To remove it, open the Fitbit app, go to the child’s profile, select the device, and remove it from the account.
Reset the Fitbit Ace 2 and Ace
If you want to reset the Fitbit Ace 2 or the Ace, follow these steps:
- Start by plugging the charging cable into a USB port or a wall plug, and then into the port on the back of the tracker.
- Make sure the pins are lined up. You’ll know the connection is secure when the battery icon pops up.
- To restart, press the button (located on the end of the charging cable) on the charging cable three times within seconds, briefly pausing between presses.
- Shortly after the first button press, the Fitbit logo appears on Ace’s display, indicating it has been restarted.
- Once the logo appears, the Ace will restart, and you can unplug it from the charging cable.
