Synchronizing Xiaomi smart watches with Android via Bluetooth: the complete guide

Introduction: Why you need synchronization

Xiaomi smartwatches are not just accessories, but full-fledged assistants that extend the capabilities of your smartphone. But to make the device work at full power, it needs to be connected correctly. Bluetooth synchronization allows you to receive notifications, monitor health, control music and even answer calls right from the wrist. However, many users have difficulty connecting the first time — the watch does not find the phone, the connection is cut off or the application gives an error.

In this article, we will look at all the stages of synchronization, from device preparation to solving typical problems, and focus on the Mi Band 7/8 Pro, Xiaomi Watch 2/3 and Redmi Watch 3, as they are most popular in 2026, and learn how to avoid common errors and what to do if the watch refuses to connect.

Important: syncs may vary depending on the version of MIUI on your smartphone and the firmware of your watch, and if your device is released before 2020, some features may not be available, as we’ll mention.

Preparing devices before synchronization

Before you start connecting, make sure both devices are ready to go, and skipping this stage often causes failures, especially if you are talking about new watches with updated software.

On your Android smartphone, check out:

• 📱 OS version - minimum requirements: Android 6.0 and higher. Android 8.0 is recommended for Xiaomi Watch 3+.
• 🔄 System Updates - Go to Settings → The phone. → Updating the system.
• 📲 Free space – Mi Fitness (or Zepp Life) app takes up ~100 MB, plus synchronization data.
• 🔋 Battery charge – the clock must be at least 50%, otherwise the process may be interrupted.

On a smartwatch:

• ⚙️ Reset to factory settings if the watch has already been used with another phone (Settings) → System system → Reset).
• 🔄 Update the firmware through the official app (if the watch supports the OTA-update).
• 🔒 Turn off the screen lock (PIN or pattern lock – this may interfere with the initial setting.

💡

If you have a Mi Band 7 or older, remove the watch from the charger before connecting – sometimes it won’t turn on if it stays on the magnetic connector.

Also make sure that your smartphone is enabled with Bluetooth and geolocation (the latter is needed to find devices in the application).If you use custom firmware (for example, LineageOS), there may be compatibility issues, we will discuss this separately.

Installation and configuration of the official application

To sync Xiaomi watches with Android, you will need an official app. Depending on the model, this can be:

• Mi Fitness – for fitness bracelets (Mi Band, Redmi Band).
• Zepp Life (formerly Amazfit) is a smartwatch (Xiaomi Watch, Redmi Watch).
• Xiaomi Wear – for new models (for example, Watch 2 Pro).

Download the app from Google Play (avoid third-party sources, it is fraught with viruses).

1. Open the app and sign up via Mi Account (or sign in if you already have an account).
2. Click Add Device and select your model from the list.
3. Follow the instructions on the screen – the application will prompt you to turn on Bluetooth and geolocation.

If your watch model doesn’t appear on the list, try:

• 🔍 Update the application to the latest version.
• 📱 Reboot your smartphone.
• ⚙️ Manually choose a similar model (for example, for Redmi Watch 3, the Mi Watch Lite profile is sometimes suitable).

Step-by-step instructions for connecting via Bluetooth

Now, to the synchronization process itself, follow the instructions carefully, and skipping even one step can lead to an error.

Step 1: Activation of the pairing mode on the clock

• On the new watch (Xiaomi Watch 3, Redmi Watch 4) hold the power button for 3-5 seconds until it appears. QR-pair.
• On Mi Band, tap the touch button and scroll to Connect.

Step 2. Search for the device in the application

1. In the app (Mi Fitness/Zepp Life) click Add Device → select the model.
2. Click Scan and the phone will start searching for available devices.
3. When the watch appears on the list, tap it.

Step 3: Confirmation of connection

• A 4-digit code will appear on the watch screen – compare it to the code in the app.
• Confirm the pairing on both devices.
• Wait until the synchronization is complete (it can take up to 2-3 minutes).

If there is an error at the confirmation stage that failed to connect, try:

• 🔄 Reboot Bluetooth on your phone (Settings) → Connections → Bluetooth → Off./On.).
• 📱 Remove the watch from the list of associated devices and repeat the process.
• 🔋 Restart the clock (hold the power button for 10-15 seconds).

💡

If the Xiaomi Watch 2 Pro isn’t located through the app, try connecting it like a regular Bluetooth headset in your phone’s settings, and then repeat the sync.

Common mistakes and their solutions

Even if you follow the instructions correctly, you can have failures, and let's look at the most common problems and how to fix them.

The device is not supported, and it occurs if:

• 📱 The phone has custom firmware (for example, Pixel Experience) without Google services.
• ⚙️ The watch is released for another region (for example, the Chinese version of the Mi Band 8 does not always work with European smartphones).
• 🔄 The application has not been updated for more than 6 months.

If none of these methods worked, try resetting the clock to the factory and repeat the procedure. In extreme cases, contact Xiaomi for support - there is a Feedback section in the application for this.

Configure notifications and additional functions

Once synchronized successfully, you can configure what notifications will arrive on the clock.

1. Open the Mi Fitness/Zepp Life app.
2. Go to the Device Profile → Notifications.
3. Turn on the switches for the desired applications (WhatsApp, Telegram, Calls, etc.).

We also recommend activating:

• 🔔 Quick answers for models with a microphone (Xiaomi Watch 3).
• 🎵 Music management – to switch tracks straight from the clock.
• 🏃 Auto-tracking workouts – the watch will automatically recognize running, walking or cycling.
• 🌙 Do Not Disturb – to turn off notifications at night.

For models with NFC (for example, Xiaomi Watch S3), you can link bank cards for contactless payment.

1. Open the Mi Pay (or Zepp Pay) app.
2. Add a map and follow the instructions.
3. On the clock, activate the function in Settings → Contactless payments.

💡

If notifications are late, check your phone's energy saving settings. add the Mi Fitness app to the battery optimisation exception list.

Compatibility of Xiaomi smart watches with different versions of Android

Not all Xiaomi watches work equally well with different versions of Android. Below is a compatibility table for popular devices:

If your smartphone runs on Android Go (a lightweight version for weak devices), some of the watch’s features may be limited, such as the Mi Band 8 Pro does not support displaying emojis in notifications on Android Go.

Important: Xiaomi watches are not compatible with HarmonyOS devices (like Huawei smartphones without Google services), and they will require a separate app that is not officially supported.

How to Improve the Stability of Bluetooth Connection

If your watch is permanently switched off or loses touch with your phone, try the following:

• 📶 Reduce distance – maximum range of Bluetooth ~10 meters, but the walls and interference reduce it to 5-7 meters.
• 🔋 Turn off the power saving mode for the Mi Fitness app in the battery settings.
• 🔄 Update the firmware of the watch - go to Settings → System system → Update of the PO.
• 📱 Reset Bluetooth cache on your phone: Settings → Annexes → Show it all. → Bluetooth → Warehouse → Clear the cache.

If the problem persists, check if the watch conflicts with other Bluetooth devices (earbuds, speakers) and sometimes helps to turn them off before syncing.

💡

On Xiaomi/Redmi/POCO smartphones, enable dual Bluetooth connectivity in Settings → Connections → Bluetooth. This will allow the watch and headphones to work simultaneously without tearing.

For Wi-Fi models (such as the Xiaomi Watch 3), you can improve stability by connecting the watch to the same network as the phone, which will reduce the load on Bluetooth and speed up data synchronization.
