How To Fix Fitbit Air Won’t Pair Or Stuck On Updating (2026)

Your Fitbit Air will not pair, or the Google Health app keeps showing an update that never finishes.

This is common with a new screenless band, and it is almost always an app, Bluetooth or firmware problem you can fix yourself.

Work through the steps below in order, which takes about 15 minutes.

Quick answer: why Fitbit Air will not pair or update

What you see	Most likely cause	Fix
“App update required” or stuck on updating	Old app version; Fitbit Air needs Google Health 5.0	Update Google Health from Google Play or the App Store
No setup prompt appears	Band is not on its charger, or setup was started from Bluetooth settings	Charge it and start from the Google Health app
Setup fails partway	Bluetooth, permissions or power saving	Toggle Bluetooth, allow Nearby devices, turn off power saving
Firmware update loops or fails	Low battery, weak connection or old firmware	Keep it on the charger, sync, and install the latest firmware
Band still not found	Stale pairing or another device on the account	Disconnect, forget the band in Bluetooth, and add it again

Why does the Fitbit Air fail to pair?

Android Central reported on May 26, 2026 that early Fitbit Air owners saw a “stuck updating” or “app update required” state because their phones lacked the updated Google Health app.

Both 9to5Google and Android Authority say the band needs Google Health 5.0, and that the Android rollout was slower than iOS.

Google said it was speeding up the Play Store rollout, so a current phone should no longer hit that wall.

Update the Google Health app first

An old app version is the first thing to rule out, because the band cannot be set up without Google Health 5.0.

On Android, open Google Play, search for Google Health and tap Update.
On iPhone, open the App Store, search for Google Health and tap Update.
Open the app, tap your profile picture on the Today tab, then tap Help to see the version number.

If you still use a sideloaded Fitbit app, note that TechRadar reported those older versions stopped working on July 15, 2026.

Start setup inside the Google Health app

Google says you must open the Google Health app for setup, not pair the band from your phone’s Bluetooth list.

Put the Fitbit Air on its charger.
Open Google Health, tap Connections at the top left, then tap Add device.
Pick your device and follow the on-screen steps.

On Android, Google says Fast Pair opens the app and connects in a few taps when the band is nearby.

Check Bluetooth, permissions and power saving

Bluetooth and permission settings cause many failed setups.

Bluetooth: turn it off, wait 10 seconds, then turn it back on.
Permissions: on Android, go to Settings > Apps > Google Health > Permissions and allow Location and Nearby devices.
Power saving: turn off Power Saving Mode, which Google says can disable Bluetooth.
Phone software: install any pending system update.

Restart the Fitbit Air on its charger

The band has no screen or menu, so Google’s restart uses the charger.

Plug the charging cable into a USB-C power source.
Place the Fitbit Air on the charger.
Hold the button on the back of the charger for 10 seconds, until the status light on the side flashes white.
Release the button, then try setup again.

Restart your phone too, then retry.

Step	Where	Time
Bluetooth off and on	Phone Settings > Bluetooth	10 seconds
Restart the band	Charger button	10 seconds
Update firmware	Google Health app, band on charger	Up to 1 hour

How do you fix a stuck firmware update?

Google lists battery and connection requirements for a Fitbit update that starts and stops.

Keep the device at 50% battery or more, and 75% or more is recommended.
Keep the Google Health app open in the background, because updates can take up to an hour.
Stay within 2 to 3 feet of the phone and turn off Bluetooth on other nearby devices.
Force quit the app, toggle Bluetooth and restart both the band and the phone.

For a Fitbit Air on firmware 20001.229.37, 20001.229.51 or 20001.229.84, Google says to place it on the charger, sync it from the app and follow the prompts to install the latest firmware.

You can check the version under the device’s System > About settings in the app.

Disconnect, forget and add the band again

A stale pairing can block a fresh connection.

In Google Health, tap Connections, select your device, then tap Disconnect device.
In your phone’s Bluetooth settings, tap the gear icon next to the band and choose Forget.
Back in the app, tap Connections > Add device and set it up again.

Remove other devices from the account

Google lists leftover devices as a cause of failed setup and sync.

Remove other Fitbit devices from your Google account under Connections.
Forget those devices in your phone’s Bluetooth list.
Uninstall Google Health from other nearby phones signed in to the same account.

Reinstall the Google Health app

If setup still fails, uninstall Google Health, reinstall it, and try again.

On Android, Google warns to confirm your OS version is supported first, or you may not be able to reinstall.

You can also clear the app cache under the Health app’s storage settings on Android.

Move a Fitbit account to Google if prompted

Google says a Fitbit account must be moved to a Google Account to use the Google Health app.

If the app prompts you to move it, finish the on-screen steps before adding the band.

When to contact Google Health support

If you have worked through every step and the band still will not pair, Google’s setup guide says to contact Google Health Customer Support.

Try pairing with a second phone first, since Google suggests that for failed updates, and tell support what you already tried.
