How To Fix Fitbit Air Not Syncing With The Google Health App

If your Fitbit Air is paired but the Google Health app keeps showing old data, the band has stopped syncing.

The cause is usually a phone permission, a drained band, a stuck connection or, occasionally, a Google-side outage, and all of them are fixable.

Work through the steps below in order; most take under five minutes, and the charger restart takes about ten seconds.

Quick answer: why a paired Fitbit Air stops syncing

What you see	Likely cause	First fix
Old data on the Today tab	Phone permission or Bluetooth is off	Allow Nearby devices, toggle Bluetooth
No status light when you double-tap	Empty battery	Charge the band (about 90 minutes from empty)
Everything fails at the same time	Google Health service outage	Wait; do not unpair
Band shows as unpaired in the app	Lost connection	Disconnect, forget in Bluetooth, add again
Update will not finish	Firmware stuck mid-update	Put it on the charger and sync from Connections

Confirm the band is connected to the app

The Air has no screen, so the Google Health app is the only place you can see its state.

Open the Google Health app.
Tap Connections at the top left.
Check that your Fitbit Air is listed and look at the battery level shown to the right of it.

If the Air is missing from the list, skip ahead to the step that re-adds it.

Force a manual sync

Google says Fitbit trackers normally sync through the day and whenever you open the app with the device nearby.

Keep the Air next to the phone.
Open the app, tap Connections, then tap Sync.

You can also press and hold on the Today tab and pull down.

Another option from Google’s troubleshooting page is to tap Connections and pull down until the progress bar fills.

If that does nothing, restart the phone and try again once the Air is still within a few feet of it.

Google’s sync page does not name the Air, so treat these as the standard Fitbit tracker steps.

Check Bluetooth and permissions on the phone

Google’s sync troubleshooting page lists these phone permissions as the first thing to check.

Open the phone Settings, then Apps, then Health.
Tap Permissions and confirm Location and Nearby devices are allowed (Nearby devices applies to Android 12 and later).
Turn Bluetooth off for about three seconds, then back on.
Make sure the phone has Wi-Fi or mobile data.

Charge the Air and read the status light

Google’s sync steps include charging the device before you try again, so do that before anything else.

Hold the cable end near the back of the band until it snaps on magnetically.

A secure connection shows as a vibration and a lit status light on the side, and a full charge from 0 to 100 percent takes about 90 minutes.

Status light	Meaning
White after a double-tap	More than 20% battery left
Red after a double-tap	Less than 20% left
Slow blinking red	Less than 20% left
Solid red	Battery is empty
Solid white while charging	Charging is complete

If the battery is completely drained, Google notes that no light may appear at all.

Restart the Air from its charger

Google’s restart page lists the won’t-sync symptom among the reasons to restart a Fitbit.

Plug the charging cable into a USB-C power source.
Place the Air on the charger.
Hold the button on the back of the charger for 10 seconds, or until the status light on the side flashes white.
Release the button and let the band restart, then sync again.

Update the Google Health app and the phone

Some early Android buyers could not finish pairing in late May 2026 because their phones did not yet have the updated app.

Android Central reported that Google said it would speed up the Android rollout, and Gadget Hacks later reported Google saying the rollout had finished.

Update Google Health in the Play Store.
Update the phone under Settings, System, System update.

Check the firmware if an update is stuck

Google’s firmware page includes Air-specific guidance for updates that start and stop.

Open Connections, tap your Air, then System and About to see the firmware number.

Google lists three versions that need extra care: 20001.229.37, 20001.229.51 and 20001.229.84.

If yours matches one of them, put the Air on its charger and use Connections, your device, then Sync.

Is it a Google outage?

If every device you own stops syncing at once, the problem may not be yours.

Gadgets & Wearables reported a Device Sync / Pairing incident on July 15, 2026, and said Google called it server-side.

Time (PDT)	Reported event
04:20	Incident began
05:41	Google acknowledged “Sync not working for all users”
07:50	Update added that Health Coach features were also unavailable

The same report said service was later restored, one Fitbit Air owner saw the band become unpaired, and delayed data could take longer to appear.

It advised against resetting devices or reinstalling the app during an outage unless Google recommends it.

Disconnect and add the Air again

Use this only after the earlier fixes have failed.

In Google Health, tap Connections, select the Air, and choose Disconnect device.
In the phone’s Bluetooth settings, find the Air and tap Forget.
Back in the app, tap Connections, then Add device, and select the Air.

If it still fails, Google’s guidance is to uninstall and reinstall Google Health, then sync.

When to contact support

Google’s firmware page says that if an update fails, you should try a different phone or contact customer support.

That is the sensible next step if the band will not sync on two phones after a restart and a fresh pairing.

Older Fitbit models have their own guides, including Fitbit Versa 4 won’t sync, Charge 6 not connecting to Bluetooth and how to reset a Fitbit.
