Fitbit Power On/Off: How to Turn It On and Off

To turn a Fitbit on, plug it into its charging cable and connect it to power; the screen will light up and the device will boot. To turn it off, open the Fitbit app, go to your device’s settings, and tap “Shut Downâ€� — or simply place it on the charger, as most models power on automatically when charging. This guide covers the exact steps for every current Fitbit model, what to do if the screen stays black, and how to restart instead of a full shutdown.

How Fitbit Power Works

Fitbit trackers and smartwatches do not have a physical power button like a phone. Instead, they are designed to run continuously, waking when you raise your wrist or tap the screen. The only way to completely power off the device is through the software menu, and the only way to power it on after a full shutdown is to connect it to a charger. This is a deliberate design choice: it prevents accidental shutdowns and keeps the device ready for activity tracking at all times.

There is a common misconception that holding the side button turns the device off. On most models, holding the button (for about 5 seconds) triggers a restart, not a shutdown. A restart clears minor glitches but does not power down the device. A full shutdown is only available from the Settings app on the device itself, or from the Fitbit app on your phone.

Turning Your Fitbit On

For all current Fitbit models (Sense series, Versa series, Charge series, Inspire series, Luxe, and Ace), the power-on procedure is identical:

1. Take the charging cable that came with your device.
2. Attach the cable to the back or side of the Fitbit (the pins align magnetically on most models).
3. Plug the USB end into a wall adapter, computer, or power bank.
4. Wait a few seconds – the screen will light up and show the Fitbit logo.

If the device was completely drained, it may take up to 10 minutes before the screen shows anything. Leave it on the charger for at least 30 minutes to get enough charge to boot fully. If the screen still does not turn on after an hour, try a different cable and adapter, and clean the charging contacts with a dry cloth.

Turning Your Fitbit Off

You have two options to power down your Fitbit:

• From the device: On Sense, Versa, Charge, Luxe, and Inspire models, go to Settings > About (or Device Info) > Shut Down. Confirm by tapping the checkmark.
• From the Fitbit app: Tap your profile picture, select your device, then tap Shut Down. This works for all Bluetooth-connected Fitbits.

After a shutdown, the screen goes completely black and the device stops tracking. To wake it, you must connect it to the charger – there is no button combination that turns it back on. This is important to remember if you plan to store the device for a long time: charge it to about 50% before shutting down, and store it in a cool, dry place.

Restarting vs. Powering Off

A restart (also called a reboot) is different from a shutdown. A restart does not disconnect from the app permanently; it just resets the software. Use a restart when the screen is frozen, the battery drains too fast, or the device is not syncing. Here is how to restart common models:

• Sense 2, Versa 4, Sense, Versa 3: Press and hold the side button for 10 seconds until the Fitbit logo appears, then release.
• Versa 2, Versa Lite, Versa: Press and hold the left and bottom right buttons for 10 seconds.
• Charge 6, Charge 5, Charge 4: Plug into the charger, then press the side button 3 times with 1 second between presses.
• Inspire 3, Inspire 2, Luxe: Plug into the charger, then press the side button 3 times with 1 second between presses.

If a restart does not fix the problem, then a full shutdown and a fresh start (via charger) is the next step. After a shutdown, the device will boot up as if it were new, but your data and settings remain intact.

Why Won’t My Fitbit Turn On?

If your Fitbit does not respond to the charger, the most likely causes are:

• Dead battery: Leave it on the charger for at least 30 minutes. The screen may stay dark while the battery is critically low.
• Dirty contacts: The gold or silver pins on the back of the device and the charger can get coated with sweat and dust. Clean them with a dry, soft cloth or a cotton swab with a tiny bit of rubbing alcohol.
• Faulty charger or cable: Try a different USB port and a different wall adapter. If you have another Fitbit charger, test with that.
• Software crash: A hard restart (as described above) often revives a device that appears dead.
• Physical damage: If the device has been exposed to water beyond its rating or dropped, internal components may be damaged. In that case, contact Fitbit support.

One thing to try if the screen is black but the device vibrates when you tap it: the screen may have crashed. Force a restart by holding the button for 15 seconds.

Battery and Charging Best Practices

Fitbit batteries are lithium-ion and last between 4 and 10 days depending on the model and usage (always-on display, GPS, and notifications drain faster). To maximize battery health:

• Avoid letting the battery drop to 0% regularly – charge when it reaches 20-30%.
• Do not leave the device on the charger for days at a time.
• Keep the charging contacts clean and dry.
• Use the original cable or a certified replacement – cheap third-party cables may not charge correctly.

If you are storing the device for more than a month, charge it to about 50% and turn it off. This prevents the battery from deep-discharging, which can permanently reduce its capacity.

Frequently Asked Questions

How do I turn off my Fitbit without the app?

On the device itself, go to Settings > About > Shut Down. The exact menu name may be “Device Info� on some models. If you cannot find it, check the user manual for your specific model.

Why does my Fitbit turn on by itself?

Fitbits are designed to turn on automatically when they detect motion or when you raise your wrist. If it turns on while on a table, it may be sensing vibrations. This is normal behavior, not a malfunction.

Does turning off my Fitbit save battery?

Yes, a full shutdown stops all tracking and background processes, so the battery will drain much slower. However, a Fitbit in shutdown mode will still lose a small amount of charge over time (about 1-2% per week) due to the battery’s self-discharge.

How do I turn on my Fitbit after it died?

Connect it to the charger. The screen will light up within a few seconds if the battery is not completely empty. If it is completely dead, it may take up to 10 minutes to show the charging screen. Leave it for 30 minutes before trying to turn it on.

Can I turn off my Fitbit from the phone app?

Yes. Open the Fitbit app, tap your profile picture (top left), select your device, then tap “Shut Down�. The device must be connected via Bluetooth for this to work.

What is the difference between restart and shutdown on Fitbit?

A restart reboots the software without disconnecting from the phone; it is used to fix glitches. A shutdown completely powers off the device; it is used for storage or to save battery. After a shutdown, you must connect to a charger to power it back on.
