Why Your Fitbit Keeps Disconnecting and How to Stop It
Your Fitbit keeps disconnecting because another device is stealing the connection, the Bluetooth pairing has gone stale, or your phone is cutting the app off in the background. A Fitbit can hold a connection to only one device at a time, so an old phone or tablet with the app installed is the first thing to rule out.
Google confirms that one device rule on its own support pages, and it explains why the connection seems to drop at random.
Every step below matches Google’s current Fitbit troubleshooting for the Google Health app as of August 2026.
Why Your Fitbit Keeps Dropping the Connection
A Fitbit syncs with one device at a time. When a second phone or tablet signed into your account comes in range, the two fight over your tracker and you see random disconnects.
Distance plays a part as well. Google says your Fitbit must stay near your phone, and a tracker left in the bedroom while you cook dinner will drop off.
Google also renamed the app in 2026. Fitbit devices now sync through the Google Health app, so advice pointing you to the old Fitbit app is out of date, and our guide on where the Fitbit app went covers that switch.
Fix 1: Remove the App From Your Other Devices
Think about every phone or tablet in the house that ever ran the Fitbit or Google Health app, including an old iPad on a nightstand.
- Uninstall the Google Health app from any other phone or tablet signed into your account.
- On those same devices, open the Settings app and tap Bluetooth or Connected devices.
- If your Fitbit is listed, remove it. On an iPhone, tap the Information icon, then tap Forget This Device. On Android, tap Settings, then Forget.
Now open Google Health on your main phone and sync. If the drops continue, keep going.
Fix 2: Restart Your Fitbit
Restarting the tracker clears its own Bluetooth glitches. Google confirms a restart never erases your activity data.
On a Charge 5 or Charge 6, swipe down from the clock screen, tap the Settings app, tap Restart Device, then tap Restart.
Other models use their own Settings app, a long press of the button, or a button on the charger, depending on the model. Google lists every model’s exact steps on its restart page, linked in the Sources below.
When the clock face comes back, try a sync.
Fix 3: Reset Bluetooth on Your Phone
Turning Bluetooth off and on forces your phone to rebuild its connections.
- Open the Settings app on your phone.
- Tap Bluetooth. On Android, tap Connected devices, then Connection preferences, then Bluetooth.
- Turn Bluetooth off, wait at least 3 seconds, then turn it back on.
Check your internet while you are in Settings. The Google Health app needs WiFi or cellular data to sync, so a tracker can hold its Bluetooth link and still show stale numbers when the app is offline.
Fix 4: Restart Your Phone
Your phone’s Bluetooth can wedge itself in a bad state that only a reboot clears.
Turn the phone fully off, then turn it back on. Open Google Health and sync before you judge the result.
Fix 5: Update the Phone, the App, and the Fitbit
Connection bugs get fixed in updates, and an outdated app talking to updated firmware is a classic source of drops.
- Install any pending update for your phone’s operating system.
- Update the Google Health app in the App Store or Play Store.
- Open Google Health and check for a Fitbit firmware update, then install it with the tracker charged and nearby.
Fix 6: Give the App the Permissions It Needs
Phones cut background apps off to save battery, and the Google Health app loses your Fitbit the moment that happens.
On an iPhone, open Settings, tap Apps, then tap Google Health. Turn on Bluetooth, Background App Refresh, and Cellular Data.
On Android, open Settings, tap Apps, tap Google Health, then tap Permissions. Turn on Location, and on Android 12 or newer turn on Nearby devices too.
Google requires Location on Android for the connection to work, so leaving it off keeps the drops coming even when everything else is right.
Fix 7: Charge Your Fitbit
A low battery can stop syncing, which is why Google puts charging on its own troubleshooting list.
Put the Fitbit on its charger until the battery icon shows a real charge, then test the connection again. If the battery itself drains fast, our guide on a Fitbit that won’t charge digs into that side.
Fix 8: Forget the Device and Pair It Again
When drops survive everything above, the pairing record itself is the suspect. The cure differs by phone.
On an iPhone, Google’s fix is to forget the device and pair fresh:
- Open the Settings app and tap Bluetooth.
- Tap the Information icon next to your Fitbit, then tap Forget This Device.
- If a message asks to allow your device to display iPhone notifications, tap Allow.
- Open the Google Health app and wait. When your phone asks to pair with the Fitbit, tap Pair.
On Android, Google’s fix at this stage is different: uninstall the Google Health app, then reinstall it from the Play Store and sign back in. Check first that your phone runs a supported Android version, because an unsupported phone cannot reinstall the app.
Force a Manual Sync to Test It
With your Fitbit next to the phone, open the Google Health app and tap Connections at the top left. On an iPhone, tap your device there too.
Tap and hold the screen, pull down until a progress bar appears, then let go. A full bar means the link works right now.
If Nothing Worked
Open Google Health, tap Connections, and remove any other Fitbit trackers or watches still tied to your account. Old devices on the account confuse the connection just like old phones do.
Still dropping after all eight fixes and a cleanup? Contact Google’s Fitbit customer support, because at that point the radio in the tracker itself is suspect.
A tracker that fails to sync at all rather than dropping now and then is a different problem, and our guide on a Fitbit that won’t sync walks that path.
FAQ
Does a Fitbit restart delete my steps and sleep data?
No. Google states a restart turns the device off and on without losing any activity data. A factory reset is the one that erases data, and none of the fixes above use it.
How close does a Fitbit need to be to my phone?
Google publishes no exact distance and says only that the device must remain near your phone. Same room is the practical rule, and walls or a floor between the two invites drops.
Can my Fitbit stay connected to two phones at once?
No. A Fitbit holds a connection to one device at a time, which is why an old phone or tablet with the app installed causes random disconnects. Uninstall the app everywhere except your main phone.
Is the Fitbit app gone?
Yes. Google moved Fitbit devices into the Google Health app in 2026, and the old Fitbit help pages now forward to the Google Health Help Center.
