Synchronizing your smartwatch with your Xiaomi phone gives you access to advanced features like health tracking, notifications, music management, and even payment. However, the connection process can be difficult β especially if you use a third-party watch (Huawei Watch, Samsung Galaxy Watch) or outdated Mi Band models. In this article, we will analyze all possible scenarios, from standard binding via Mi Fit to solving errors like βdevice does not seeβ or βconnection is permanently brokenβ.
It is important to consider that the connection algorithm depends on three key factors: 1) the watch model (e.g. Xiaomi Watch 2 Pro vs Amazfit GTR 4), 2) the smartphone firmware version (MIUI 13/14/15), 3) regional restrictions (in China and global versions, different applications are used).
We tested the instructions on current devices from 2023 to 2026, so all the steps are in line with the latest updates.
If you've never used a wearable before, don't worry: it takes no more than 5-7 minutes to prepare properly, and for experienced users, we've created unique life hacks to speed up synchronization and save battery life with constant connection.
1.What watches are compatible with Xiaomi phones?
Xiaomi, Redmi and POCO phones support the connection of almost all smartwatches, but there are nuances:
- πΉ Watch brand Xiaomi: Xiaomi Watch S3, Watch 2 Pro, Mi Watch Revolve β work through the official Mi Fit app (for global versions) or Zepp Life (for Amazfit models).
- πΉ Watches of third-party brands: Huawei Watch GT, Samsung Galaxy Watch, Apple Watch β require the installation of branded apps (Huawei Health, Galaxy Wearable), but may limit features (for example, no payment Mi Pay).
- πΉ Fitness bracelets: Mi Band 8, Honor Band 6 β connect via Mi Fit or Zepp Life, but have a reduced functionality compared to the watch.
Check compatibility on the watchmakerβs official website before buying, for example, Apple Watch can technically be connected to Xiaomi via third-party apps like WatchDroid, but notifications and calls wonβt work due to Appleβs restrictions.
| Model clock | Application for connection | Support for MIUI | Features |
|---|---|---|---|
| Xiaomi Watch S3 | Mi Fit / Zepp Life | Complete (MIUI 12+) | Payment Mi Pay, 150+ modes of sports |
| Amazfit GTR 4 | Zepp Life | Complete (MIUI 11+) | Autonomy up to 14 days, stress sensor |
| Huawei Watch GT 4 | Huawei Health | Partial (no Mi Pay) | Requires HMS Core enabled |
| Samsung Galaxy Watch 6 | Galaxy Wearable | Limited (no synchronization with Mi Health) | It only works with Samsung Health. |
2. Preparing Xiaomi phone for connection
Before synchronization, perform the mandatory settings on your smartphone:
- Update MIUI to the latest version via Settings β About Phone β System Update. Older versions (below MIUI 12) may not support Bluetooth 5.2, leading to communication breakdowns.
- Turn on Bluetooth and geolocation (yes, thatβs important!): Go to Settings β Connections β Bluetooth and activate both settings.
- Allow auto-run for Mi Fit/Zepp Life: Settings β Applications β Application Management β Mi Fit β Auto-run
- Turn off power saving mode for stable Bluetooth operation: Settings β Battery β Power saving mode β Disable.
If you use Xiaomi with Global ROM, you donβt need to do any more manipulation, and owners of the Chinese ROM will have to install Google Services manually, otherwise Mi Fit wonβt start.
Update MIUI to the latest version
Enable Bluetooth and geolocation
Allow autoplay for Mi Fit/Zepp Life
Turn off the power saving mode
Install Google Services (for China) ROM)-->
β οΈ Attention: On phones from China ROM Without Google Services, Mi Fit will give you an error, "No Internet connection" even if the network is working.
3. Step-by-step instructions: how to connect the watch to Xiaomi
Consider the universal algorithm on the example of Xiaomi Watch S3 and Mi Fit application (similar to Zepp Life):
- Install the app: π± For global versions of watches: download Mi Fit from Google Play. π For Chinese versions: use Zepp Life (available on the App Store or official website).

- π Confirm the pairing on both devices.
- Update your firmware (if available): Mi Fit β Device Profile β Software Update
The process takes 2-3 minutes. After successfully connecting, the watch will display a βConnectedβ notification on the screen, and the application will display data on battery charge and synchronization status.
What if the watch doesnβt connect the first time?
4. Solving common connection errors
Even with the right settings, users are facing problems.-5 mistakes and their solutions:
| Mistake. | Reason. | Decision |
|---|---|---|
| "Can't find the device." | Bluetooth is disabled or the clock is in airplane mode | Turn on Bluetooth on both devices, reboot the clock |
| "Server unavailable." | Problems with the Internet or VPN | Disable VPN, check the connection to the network |
| "The device is already tethered." | The clock was synced to another phone. | Reset the clock to factory settings (Settings β System β Reset) |
| "Incompatible version of the application" | Outdated software on a watch or phone | Update Mi Fit and watch firmware |
| "Constantly breaking the connection." | Energy saving mode or background optimization | Turn off optimization for Mi Fit in battery settings |
If Huawei or Samsung watches donβt connect to Xiaomi, check:
- π§ Whether identified HMS Core (for Huawei)?
- π§ Notifications for Galaxy Wearable App Allowed?
- π§ Is it blocking? MIUI Optimization of background processes? (Switched off through Settings) β Special facilities β MIUI Optimization)
β οΈ Attention: On phones with MIUI 14+ And the Xiaomi Watch 2 Pro can get a bug with "infinite sync" so you can turn off Automatic Data Sync in the Mi Fit settings and turn it on again.
5. Set up notifications and additional functions
After connecting, set the clock to your needs:
- π± Notifications: Mi Fit β Device profile β Notifications β Select applications We recommend leaving only messengers and calls so as not to overload the clock.
- π΅ Music control: Enable the option "Player Control" in the settings of the watch - this will allow you to switch tracks directly from the wrist.
- π³ Contactless Payment: For Mi Pay, link your bank card to the Mi Fit app (available only for global watch versions).

To extend the life of the watch battery, turn off the permanent pulsemeter (Settings β Heart Monitor β Measure every 30 minutes) and reduce the brightness of the screen to 50%.
6. How to unplug your watch from your Xiaomi phone
If you want to reset the connection (for example, to sell a watch or connect to another phone), do the following:
- Through the app: Mi Fit β Profile β Delete the device β Confirm
- Through the settings of the clock: On the clock: Settings β System β Disconnect from the phone
- Reset to factory settings (if the clock is glitchy): On the clock: Settings β System β Reset β Confirm
After the shutdown, all data (steps, pulse, training) will be stored in the Mi Fit/Zepp Life account, but sync with your phone will stop. To connect the watch to the new device, repeat the binding process from scratch.
β οΈ Warning: If you sell watches, make sure to reset to factory settings! otherwise the new owner will be able to see your personal details (training history, notifications and even tied cards in Mi Pay).
7. Application comparison: Mi Fit vs Zepp Life vs third-party
The choice of the app depends on the model of the watch and the desired functions.
| Annex | Supported devices | Pluses | Cons |
|---|---|---|---|
| Mi Fit | Xiaomi Watch, Mi Band | Official support, Mi Pay, simple interface | Limited sleep analytics, no dial customization |
| Zepp Life | Amazfit, some Xiaomi Watch | Expanded health statistics, more dials | No Mi Pay, it's harder to set up notifications |
| Notify & Fitness | Any watch with Bluetooth | Support for unofficial firmware, flexible settings | No official support, possible bugs |
| Huawei Health | Huawei Watch | Accurate heart monitoring, integration with Huawei ecosystem | Does not work with Mi Pay, requires HMS Core |
For most Xiaomi users, the best choice will remain Mi Fit β it works more stable with native devices and supports all key functions. Zepp Life should be considered only by owners of Amazfit or those who need detailed sleep analytics.
