A restart clears temporary software problems without erasing your data

A restart of your Fitbit Charge 5 forces the device to shut down and start fresh, which fixes most glitches—frozen screens, unresponsive buttons, or connection drops. The restart process takes about a minute and does not delete your activity history, personal settings, or synced data. Everything stays on the device and in your Fitbit app.

You do not need a computer, a special tool, or a factory reset. A straightforward restart is the first troubleshooting step when your Charge 5 stops responding or behaves oddly.

Key Takeaways

  • Hold the button on the back of the Charge 5 for 8 to 10 seconds until you see the Fitbit logo on the screen, then release.
  • A restart clears temporary software glitches and does not erase your activity data, goals, or personal settings.
  • If the screen remains frozen or unresponsive after a restart, try charging the device for at least 30 minutes before restarting again.
  • A restart is different from a factory reset—a restart keeps all your data, while a factory reset erases everything.

Step-by-step restart process

Locate the single button on the back of your Charge 5, near the bottom edge. This is the only physical button on the device. Press and hold this button firmly.

Keep holding for 8 to 10 seconds. You will see the Fitbit logo appear on the screen—this is the sign that the restart is working. Once the logo appears, release the button when ready. The device will complete the restart on its own, which takes another 10 to 15 seconds. You may see a brief loading animation or blank screen during this time.

When the restart finishes, your Charge 5 will display the main clock face or home screen. Your device is now restarted and ready to use. All your data remains intact.

When to restart instead of other fixes

A restart works best for temporary problems: a frozen screen, buttons that do not respond, the device not syncing with your phone, or the app showing outdated information. If your Charge 5 is straightforward slow or occasionally glitchy, a restart often solves it without any other action.

Do not restart if your device is powered off completely. If the screen is black and will not turn on, charge the device for at least 30 minutes first. A completely drained battery may not respond to the restart button press. After charging, try the restart process again.

Charging before a restart if the device is unresponsive

If your Charge 5 does not respond to the button press at all—no logo appears, no vibration, nothing happens—the battery may be too low. Connect the device to its charging cable and let it charge for 30 minutes to an hour.

While charging, you may see a lightning bolt icon on the screen or no display at all. This is normal. After 30 minutes, disconnect the charger and try the restart process again. This time, the device should have enough power to respond to the button hold.

What happens during a restart

When you hold the button, the Charge 5 closes all running processes and clears temporary memory. This is why it fixes problems caused by software glitches—the device is not trying to remember what it was doing before. The Fitbit logo appears as the device powers back on and reloads its core software.

Your personal data—steps, heart rate history, sleep records, goals, and settings—is stored separately from the temporary memory. A restart does not touch this storage, so nothing is lost. Your synced data in the Fitbit app on your phone is also unaffected.

Restart versus factory reset

A restart is a soft reboot that clears temporary problems and keeps all your data. A factory reset erases everything on the device and returns it to the state it came in—no activity history, no personal settings, no saved data. You would only do a factory reset if a restart does not fix the problem and you are willing to lose all local data (though your synced history in the Fitbit app remains).

Start with a restart every time. Only move to a factory reset if the device remains broken after a restart and a full charge.

What to do if a restart does not fix the problem

If your Charge 5 still does not work after a restart, try these steps in order: charge the device fully (at least 2 hours), restart again, and then check that your Fitbit app is up to date on your phone. Open your phone's app store and search for Fitbit to see if an update is available.

If the problem persists after these steps, the device may have a hardware issue. Contact Fitbit support through the Fitbit app (tap your profile icon, then Help) or visit Fitbit's support website. Fitbit offers a warranty that covers hardware defects, and support can tell you whether your device qualifies for repair or replacement.

Frequently Asked Questions

Will a restart delete my activity data?

No. A restart only clears temporary memory and does not touch your stored activity history, heart rate data, sleep records, or personal settings. Everything remains on your device and in your Fitbit app.

How long does a restart take?

The entire process takes about one to two minutes. Hold the button for 8 to 10 seconds until the logo appears, then release and wait 10 to 15 seconds for the device to finish restarting and show the home screen.

What if the button does not work or nothing happens?

The battery may be too low to respond. Charge the device for at least 30 minutes, then try the restart process again. If the button still does not work after a full charge, contact Fitbit support—this may indicate a hardware problem.

Can I restart my Charge 5 while it is charging?

Yes, you can hold the button and restart the device while it is plugged in. There is no harm in doing so, though it is not necessary. Most people restart when the device is not charging, straightforward for convenience.

Do I need to restart my Charge 5 regularly?

No. Restart only when you notice a problem—a frozen screen, unresponsive buttons, or sync issues. Regular restarts are not needed for normal operation or maintenance.
