If your Fitbit Charge 4 is frozen, will not sync, stops tracking activity, or does not respond to taps, a restart is a sensible first troubleshooting step. A restart reboots the tracker without intentionally deleting your activity data. The Charge 4 has two main restart methods: use Settings when the screen works, or connect the charging cable and hold the tracker’s button when it is unresponsive.

Quick Answer: Restart Fitbit Charge 4
If the touchscreen works: On the tracker, open Settings > About > Reboot Device. Follow the on-screen prompt if one appears.
If the tracker is unresponsive: Connect the Charge 4 securely to its charging cable. Press and hold the button on the tracker for about 8 seconds, then release it when you see a smiley face and feel the tracker vibrate. This indicates that it has restarted. The official manual describes this charger-connected button procedure, rather than a general 15-second hold.
Use a compatible Charge 4 charging cable and a reliable USB power source. Check that the charging contacts line up correctly and that the tracker is seated securely in the cable. If no battery indicator appears, inspect the contacts for dirt and try a known-working USB power source.
Do not insert a paper clip or other object into the small hole on the back of the Charge 4. It is a sensor opening, not a reset button, and inserting an object can damage the tracker. If the tracker remains unresponsive after charging and restarting, consult Google Fitbit’s Official Restart Instructions or contact support.
A very low battery can make the screen appear frozen or prevent the tracker from responding. Let it charge for a while before retrying the restart. If it becomes unusually hot, shows physical damage, or the battery appears swollen, disconnect it and seek qualified support rather than continuing to charge it.
Restart vs. Factory Reset: What Is the Difference?
| Action | What happens | Best use |
|---|---|---|
| Restart / Reboot Device | Reboots the tracker and normally keeps activity data | Sync problems, frozen screen, missed tracking or notifications |
| Factory reset / Clear User Data | Erases personal data stored on the tracker and returns it to setup state | Before transferring ownership or when specifically advised after other troubleshooting |
Do not factory-reset the Charge 4 just to fix an ordinary freeze. Try a restart first. If you are selling or giving away the tracker, use its Settings > About > Clear User Data option and follow the confirmation steps.
Troubleshooting If Your Charge 4 Still Will Not Restart
The screen stays black
Connect the tracker to its charging cable and confirm that the contacts are aligned. Try a reliable USB power source and allow it to charge before attempting the 8-second button procedure. If there is still no display or vibration, the cable, battery, or tracker may need inspection.
The Fitbit Charge 4 will not sync
After restarting, keep the tracker close to your phone, confirm Bluetooth is enabled, open the Fitbit app, and allow the device time to sync. If needed, check app permissions and phone connectivity before removing and re-adding the tracker.
The tracker is stuck on the logo or keeps rebooting
Connect it to its charger and try the official restart steps once. If it remains stuck or repeatedly reboots, check the manufacturer’s troubleshooting guidance and contact support. Avoid repeated random button combinations or unofficial firmware tools.
Make sure the tracker is correctly seated in the charging cable so the button lines up with the cable’s button opening. If the physical button is damaged or does not register, seek repair advice rather than pressing excessively.
When Should You Restart Fitbit Charge 4?
- The tracker will not sync with the Fitbit app.
- The screen is frozen or does not respond to taps or swipes.
- Steps, heart-rate readings, or other activity data stop updating.
- Notifications or reminders are not appearing as expected.
- The tracker behaves unusually after a temporary software issue.
A restart is a troubleshooting step, not a guaranteed fix for a damaged battery, faulty charging cable, or hardware failure.
Frequently Asked Questions
Will restarting Fitbit Charge 4 delete my data?
No. A normal restart reboots the tracker and should not erase your activity data. A factory reset or Clear User Data action is different and erases personal information stored on the device.
If the tracker is unresponsive, connect it to the charging cable and hold its button for about 8 seconds. Release it when the smiley face appears and the tracker vibrates.
Can I restart Fitbit Charge 4 without the charger?
If the screen responds, use Settings > About > Reboot Device. For an unresponsive tracker, the documented hardware restart procedure uses the charging cable.
Does restarting fix Fitbit Charge 4 syncing problems?
It can resolve temporary issues, but it may not fix Bluetooth, phone permission, app, or account problems. If syncing still fails, check the Fitbit app and phone settings.
Is restart the same as factory reset?
No. Restarting reboots the tracker without intentionally erasing data. A factory reset or Clear User Data option erases personal data and should be used only when appropriate.
Why should I not put a pin into the small hole on the back?
The small hole is a sensor opening, not a reset pinhole. Inserting an object can damage the tracker.
