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 signs and symptoms, one of the best (and simple) fixes 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 (also called rebooting or a soft reset) your Fitbit turns it off and on without deleting any activity data.
- Resetting (also called factory reset or a hard reset) your Fitbit wipes all the data from your device and turns it off and back on. It’s like starting with a new Fitbit, fresh from the factory.
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 particular attention to the charging pins and sensors. Never insert anything into these holes outside of the directions. Inserting items like paper clips, tools, and such will likely damage your Fitbit permanently.
Restart a Fitbit Sense series, Versa series, Ionic, or Blaze
- For the Fitbit Sense series, Versa 2 and above, hold the side button for at least 10 seconds until you see the Fitbit logo on the screen, and then release the button.
- For older models like the original Versa, Blaze, or Ionic, press and hold the back and bottom buttons until you see the Fitbit logo on the screen. Then release the buttons.
- Alternatively, go to Settings > Shutdown or Settings > About > Shutdown. Then press the side button again to turn it back on.
Restart a Fitbit Luxe and Inspire 2/3
- If your Fitbit responds to your taps, open Settings > Restart Device > Restart or Settings > Reboot Device.
- If your Fitbit doesn’t respond to taps, try the following:
- For the Luxe, connect it to its charging cable, then press the button on the charging cable three times, pausing for 1 second between presses.
- For the Inspire 2 or 3, connect it to the charger so it’s charging, and then press and hold the side buttons for at least 10 seconds.
- Wait 10 seconds until the Fitbit logo appears on its screen.
Restart a Fitbit Inspire, Inspire HR, or Ace 2/3
- Plug the charging cable into the USB port on your computer or any UL-certified USB wall charger.
- Attach the Inspire or Ace 2/3 to the charging cable. Verify the pins on the charging cable connect securely to your Fitbit.
- Press and hold the button for 5 seconds.
- Keep pressing until you see a smiley icon and the Inspire or Ace vibrates.
- Disconnect the Fitbit from power and test performance.
You can now reboot your Fitbit Inspire via the Settings app on your device itself.
- Go to Settings and scroll down to Reboot device.
- Then, follow the on-screen instruction to press the screen for 3 seconds.
Restart a Fitbit Charge 3, 4, or 5
- On your Fitbit Charge, open the Settings app.

- Choose Reboot Device or Restart.
- When restarted, test your device.
Restart a Fitbit Charge (all other models)

- Connect the charging cable to the tracker. Verify that the pins are locked when your Charge vibrates and a battery icon appears on-screen.
- Press and hold the side button to restart.
- Charge 2—press and hold the button for 4 seconds until you see the Fitbit logo and the device vibrates. Release the button.
- Charge 3 & Charge 4—press and hold the button on your tracker for 8 seconds until you see a smiley icon and the device vibrates. Then, release the button.
- Charge 5–press the button on the charger’s end three times, pausing for 1 second between presses. Wait until the Fitbit logo appears on your Charge 5’s screen (usually about 10 seconds.)
- Disconnect the Charge from power and test performance.
Restart a Fitbit Ace or Fitbit Alta

- Clip the charging cable to the port on the back of the tracker. Ensure the charging cable is locked securely to the dock by verifying the battery icon displays on-screen.
- Press the button on your charging cable three times, pausing between each press.
- Wait until you see the Fitbit logo and the tracker vibrates.
- Disconnect the Ace or Alta from its charging cable and test performance.
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 data–it’s like starting with a fresh & new Fitbit.
In cases where your Fitbit continues to perform poorly, refuses to sync data, or continues not to be recognized by your phone, computer, etc., even after a restart, we recommend you reset your Fitbit.
When you reset a Fitbit, it removes your data and returns it back to its factory defaults, so you must set up your Fitbit again and re-pair it with the Fitbit app and your phone. It’s like starting over with a fresh, new device.
When you perform a factory reset, the reset clears 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, clock faces, and notifications.
Once reset, you must pair your Fitbit again to the Fitbit app on your phone.
Resetting your Fitbit DOES NOT remove your Fitbit account!
Reset a Fitbit Sense series, Versa series, Ionic, or Charge 3/4
- Go to the Settings app (gear icon.)
- Choose About or Device Info.
- Select Factory Reset or Clear User Data.
- Confirm with Yes. For the Charge series, swipe up and tap the checkmark, then release.
- When you see the Fitbit logo on its screen and the device vibrates, your Fitbit reset back to its factory defaults.
Factory reset using the buttons only
If you cannot access the on-screen menus, try resetting using just your Fitbit button(s).
We recommend only following these steps when you cannot access the Settings app on your Fitbit’s screen.
For the Fitbit Sense series and Versa series (one-button models)
- Press and hold the side button until the screen turns off.
- After the screen turns off, you should feel a short vibration.
- As soon as you feel the vibration, release the side button and immediately press and hold that button again.
- Keep 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.
- 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
- Hold the back button for about 8 seconds.
- Wait for the Fitbit logo to appear, then disappear. Release the button briefly for less than 2 seconds.
- 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)
- Hold all buttons down for around 10 seconds until the Fitbit logo appears, then disappears.
- 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.
Your Fitbit should show the setup screen if you followed the process correctly. Now, 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.
Reset a Fitbit Luxe, Inspire 3, and Charge 5
- Open the Settings app.
- Choose Device Info and tap Clear User Data.
- Swipe up on the screen, then when asked, press and hold the screen for 3 seconds.
- After 3 seconds, release and wait for the Fitbit Logo to appear on your screen.
- When your Charge 5 or Luxe vibrates, your device reset and erased all its current data.
- If the device doesn’t vibrate, repeat these steps.
Reset a Fitbit Inspire/HR/2 or Ace 2/3
- For Ace 2 and Ace 3 only, connect your device to the charging cable.
- Go to the Settings app.
- Choose Clear User Data.
- When asked, press the screen for 3 seconds and then release it immediately.
Reset a Charge or Charge 2
- Connect your Fitbit Charge to its charger and a USB power source.
- Press and hold the side button for 2 seconds, then remove the charging cable from the USB power source while keeping the Charge’s side button pressed for another 9 seconds.
- Release the side button, pause for a second, then press and hold it again.
- Wait for the screen to flash ALT, release the button, pause for another second, and press and hold the side button again after the Charge vibrates.
- Please wait for the screen to say Error, then release the button, pause for another second, and press and hold it again.
- Wait for the screen to show Erase, then release the button.
- Reattach the cable to its USB power source–look for your Charge to read 0:00 as the current time. If not, follow the steps again.
Reset a Fitbit Blaze or Alta
- Use the Fitbit app or a browser and visit your Fitbit account user dashboard.
- In the app, tap your account icon or the menu button in the top corner. In your user dashboard, tap the Settings icon (gear) and choose Settings.
- Choose your Fitbit Blaze or Alta from the list of Devices.
- Tap Remove This Blaze or Alta.
- If you don’t see this option, swipe up.
- Once removed from your account, choose to unpair or forget this device in your phone’s Bluetooth settings.
- For the Blaze, press and hold both the left side’s back and bottom right buttons until you see the Fitbit logo on-screen.
- For the Alta, follow the restart instructions listed above.
What to do if your reset Fitbit won’t pair to your phone and the Fitbit app
Sometimes, after resetting your Fitbit remains in your phone’s Bluetooth settings and prevents it from re-pairing to the Fitbit app.
In that case, open your phone’s Bluetooth settings and choose to forget your Fitbit. Then, open the Fitbit app and re-pair it.
Hopefully, you learned how to restart or factory reset your Fitbit and that doing so fixed any problems it was having.
