Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsMost Xiaomi smartwatch connection failures are fixed without replacing hardware: identify whether pairing or synchronization is failing, keep the watch near the phone, verify Bluetooth and Mi Fitness permissions, remove any stale pairing, update both sides, and restart them. Factory reset is a later step because it can erase watch data and its procedure differs by model.
The exact menu names depend on the watch model, Android or iPhone software, and whether you are connecting to a new phone. Use the model-specific notes below rather than assuming that one Xiaomi instruction applies to every watch.

First identify what has failed
“Won’t pair” and “won’t sync” describe different stages. Pairing (also called binding) creates the relationship between the watch, the phone’s Bluetooth connection, and the Mi Fitness app. Synchronization happens after that relationship exists and transfers health, workout, settings, or other account data.

Before changing anything, note the exact watch name (for example, the full Xiaomi or Redmi model and size), the phone operating system, and whether the same Xiaomi account is being used. Xiaomi’s menus and reset behavior are not universal across generations.

Make the low-risk connection checks
Keep Bluetooth active and the devices close
Turn on Bluetooth on the phone and leave the watch beside it while setting up. Do not walk away or leave the watch on a different room’s charger during discovery. Xiaomi’s proximity advice is especially explicit for some models, but it should not be treated as a universal published distance specification.
Open Mi Fitness rather than relying only on the phone’s Bluetooth screen. The app is the place where Xiaomi watches are normally discovered and bound. If Mi Fitness is already open, leave the device page and start discovery again, or pull down to refresh where that control is available.
Grant the permission that pairing actually needs
On the Xiaomi Watch S5 46mm FAQ, Xiaomi states: “The Nearby devices (Bluetooth) permission is required to pair the watch and establish a stable Bluetooth connection.” On Android, this permission may be listed as Nearby devices or Bluetooth. On an iPhone, the wording and location differ by iOS version.
Open the phone’s app-permission page for Mi Fitness and allow the Bluetooth or nearby-device permission. Only grant other permissions when their feature needs them: calls can require phone or microphone access, messages and alerts use notification access, location features can request location permission, and QR scanning can request camera access. Do not assume that every permission shown by the app is required for the basic Bluetooth handshake.
If the permission was previously denied, switch it on, close Mi Fitness completely, reopen it, and retry. If the phone has a system-level Bluetooth privacy switch in addition to the app permission, both must be enabled.
Stop the phone from suspending Mi Fitness
Battery saver, background limits, and automatic app cleanup can disconnect a watch after the screen is locked. In the phone’s battery or app-management settings, allow Mi Fitness to run in the background. On phones that offer them, use an unrestricted battery setting, whitelist the app from optimization, enable autostart, or lock it in the recent-apps view. The labels vary substantially between Android manufacturers and versions; iOS uses its own background and notification controls.

Do not enable an extreme power-saving mode while testing. Xiaomi’s REDMI Watch 4 guidance lists power-saving mode and background restrictions among possible causes of a failed connection. Once pairing works, you can test a less restrictive battery setting to find the lowest setting that still permits reliable synchronization.
Update Mi Fitness and watch software
Install any available Mi Fitness update. In the app, check the watch’s device page for a firmware update and let it finish while the phone and watch remain near each other. Also install a phone operating-system update when the model’s support instructions call for it. A mismatch between an old app, watch firmware, and current phone software can leave discovery or synchronization incomplete.
Pair a watch that Mi Fitness cannot find
- Open Mi Fitness and start Add device or the equivalent discovery command. Use the app’s scanner or device list, not a random third-party Bluetooth utility.
- Keep the watch awake and close to the phone. If it has left its pairing screen, return to that screen before scanning again; Xiaomi lists leaving the pairing screen as a possible REDMI Watch 4 failure condition.
- Check Bluetooth and Nearby devices permission again. A phone can show Bluetooth as enabled while Mi Fitness still lacks permission to discover nearby hardware.
- Look for an old watch entry in the phone’s Bluetooth settings. If the watch was previously connected, choose the option to forget or remove that saved device. Android commonly places this under Settings and Bluetooth or Connected devices; iPhone commonly places it under Settings, Bluetooth, the information button, and Forget This Device. Your labels may differ.
- Turn Bluetooth off, wait briefly, and turn it on again. Return to Mi Fitness and run discovery once more.
- Accept every pairing confirmation. If a code or confirmation appears on both phone and watch, confirm it on both. Xiaomi notes that failing to confirm can leave binding unfinished even though the watch was visible.
- Leave Mi Fitness open until binding completes. Do not lock the phone or switch to a battery-saving mode during the initial exchange.
If the watch is visible in the phone’s Bluetooth list but Mi Fitness cannot finish binding, remove that Bluetooth record and repeat the process from Mi Fitness. A Bluetooth record by itself is not proof that the Xiaomi app has completed its binding process.
Fix a watch that is paired but will not sync
Confirm the connection state in Mi Fitness
Open the watch’s device page in Mi Fitness and verify that it says connected rather than merely showing a remembered device. If it is disconnected, use the app’s reconnect or refresh control before attempting a data transfer. If the app cannot reconnect, follow the stale-pairing procedure in the next section instead of repeatedly pressing sync.
Refresh manually and check the network
For a connected watch, pull down on the relevant Mi Fitness page to refresh or use its manual sync command, if shown. Xiaomi’s general synchronization guidance also calls for checking the phone’s network connection. Reconnect to Wi-Fi or temporarily try mobile data, then refresh again. Bluetooth carries the local watch link, but the app may need network access to complete account synchronization.
Update before troubleshooting deeper
Check for updates to Mi Fitness and the watch firmware. If the phone’s software is out of date and the model’s support guidance recommends an operating-system update, install it as well. Retry synchronization after each update has completed rather than starting several changes at once.

Restart in a controlled order
- Close Mi Fitness, then reopen it.
- Turn the phone’s Bluetooth off and on.
- Restart the phone.
- Restart the watch using its normal power menu.
- Open Mi Fitness, confirm the watch is connected, and request a refresh or manual sync.
This sequence clears a temporary Bluetooth or app state without deleting the watch’s stored data. If a phone offers a Bluetooth-cache command, use it only when the model’s instructions and the phone’s settings actually provide that option; it is not a universal step.
Remove stale pairing information and bind again
Use this procedure when the watch is listed but discovery loops, a previous phone was used, or the app says binding failed after a Bluetooth connection appeared.
- In Mi Fitness, open the watch’s device page. If an unbind, remove-device, or similar command is available while connected, use it and wait for completion.
- In the phone’s Bluetooth settings, forget or remove every saved entry for that watch. Remove only the watch entry, not unrelated headphones or other accessories.
- Toggle Bluetooth off and on, then restart the phone if the old entry keeps reappearing.
- Open Mi Fitness and choose Add device. Select the exact watch model shown by the app.
- Confirm the pairing request or matching code on both the phone and watch.
- Keep the app in the foreground until the device page reports a completed connection.
If the watch is still attached to the old phone, that phone can compete for the connection. Turn its Bluetooth off or move it away during the new attempt. Do not repeatedly pair from the system Bluetooth page and then expect Mi Fitness to inherit a complete binding; start the final attempt inside Mi Fitness.
What to do when you changed phones
New-phone behavior depends on the watch generation and account state. If the old phone still works, the safest first option is to open Mi Fitness there while the watch is connected and unbind it from the device page. Then remove the old Bluetooth entry and bind the watch from Mi Fitness on the new phone.
Some newer Xiaomi devices expose a watch-side command such as Settings > System > Connect new phone. Use it only if that exact menu exists on your model. Other models require a factory reset before the new phone can bind.
On supported devices, signing in to the same Xiaomi account can permit a new-phone connection without a reset. Using a different account may trigger a reset or require the watch to be cleared first. Because support differs by model and generation, check the exact model’s Xiaomi instructions before assuming that an account change will preserve the binding.

Recommended Free Tools
Use a factory reset only after the other steps
A reset is appropriate when stale binding cannot be removed, the watch remains tied to an inaccessible phone, or the model’s official new-phone procedure requires it. It is not the first response to a missing sync because it can erase data stored on the watch.
- Synchronize or transfer any data that Mi Fitness can still access.
- Record the exact watch model and read its official reset instructions. The menu path is not identical across Xiaomi and Redmi watches.
- Make sure the watch has enough power to complete the reset and subsequent update.
- Run the reset from the watch or Mi Fitness only when the model’s instructions specify that method.
- After the watch returns to setup, remove any old phone Bluetooth entry, open Mi Fitness on the target phone, and bind it as a new device.
Do not assume that a reset guarantees recovery of data that never reached Mi Fitness. It clears the watch’s local state; it does not establish that every unsynchronized workout or health record is stored elsewhere.
Model-specific cautions
| Model or platform note | Use it for | Do not generalize it to |
|---|---|---|
| Xiaomi Watch S5 46mm: Xiaomi identifies Nearby devices/Bluetooth permission as required for pairing and recommends allowing the app to remain active in the background. | Discovery and stable Bluetooth setup on that model. | Every permission requested by every Xiaomi watch, or every phone’s identical menu wording. |
| Xiaomi Watch S5 and HarmonyOS: Xiaomi reports current compatibility issues affecting message-notification synchronization. | A case where the watch pairs and health data works but message alerts do not. | A universal explanation for failed pairing or all health-data sync failures. |
| REDMI Watch 4: Xiaomi lists Bluetooth being off, leaving the pairing screen, distance, background restrictions, and power-saving mode as possible causes. | Checking discovery conditions for that model. | A published Bluetooth range or a rule that every Xiaomi watch has the same limit. |
| Xiaomi Watch 5: Xiaomi’s guidance includes restarting the watch, checking phone Bluetooth and proximity, updating Mi Fitness and phone software, and possibly clearing Bluetooth cache. | Model-appropriate recovery when the phone provides a Bluetooth-cache option. | A required cache-clearing step on phones that do not expose one. |
When a model-specific FAQ conflicts with a generic suggestion, follow the instruction written for the exact watch and phone combination.
Match the symptom to the next action
The watch appears in Bluetooth but not in Mi Fitness
Forget the saved Bluetooth entry, toggle Bluetooth, verify Nearby devices permission, and restart discovery from Mi Fitness. The system list can contain a stale or incomplete record that prevents the app from completing binding.
Quick wins for a faster PC:
Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Repair Windows errors before they cause bigger problemsFix Now →A pairing code appears, then the process times out
Keep both screens open, confirm the code on both devices, and prevent the phone from locking or entering power-saving mode. If it fails again, remove the old pairing record on the phone before retrying.
The watch connects only while Mi Fitness is open
Review battery optimization, background activity, autostart, and recent-app locking for Mi Fitness. Reconnect after changing those controls, then test with the phone screen locked.
Sync begins but no new workout or health record arrives
Confirm the device page says connected, reconnect the phone to Wi-Fi or mobile data, refresh or manually sync, and check app and firmware updates. Restart Bluetooth, phone, watch, and Mi Fitness if the transfer remains stalled.
Only notifications are missing
Check notification permission and background operation separately from health-data synchronization. On the Xiaomi Watch S5, Xiaomi specifically documents a HarmonyOS message-notification compatibility issue; that does not establish that Bluetooth pairing itself is broken.

Pick the symptom - the matching free tool is one click away.
When to contact Xiaomi support
Contact Xiaomi after-sales service when current Mi Fitness and watch software are installed, model-appropriate permissions and background settings are allowed, stale pairing has been removed, and the watch still cannot bind after the documented reset or re-pairing process. Include the exact model, phone model and operating system, Mi Fitness version, what appears on each screen, and which steps changed the behavior.
The troubleshooting guidance does not establish whether an individual watch has a hardware fault, nor does it establish repair pricing, warranty coverage, or service turnaround. Those answers depend on the device, country, purchase terms, and service diagnosis.
