Smart watches Xiaomi have long ceased to be just an accessory - they have become a full-fledged assistant in everyday life. From tracking your physical activity to managing notifications from your phone, these devices can do a lot. However, the first step to their effective use is the correct connection to a smartphone based on Android. Many users encounter difficulties at this stage: the application does not find the clock, synchronization is interrupted, or functions do not work correctly.
In this article we will analyze the entire connection process from A to Z - from preparing devices to setting up additional functions. We will pay special attention to the nuances that are often missed in standard instructions: choosing a connection protocol (Bluetooth 5.0 vs BLE), setting permissions on Android 13/14, and even how to avoid common mistakes when you turn it on for the first time. If you have just unpacked Mi Band 8 Pro, Watch 2 Pro or any other brand model, this guide will help save time and nerves.
It is important to understand that the connection process may differ slightly depending on the watch model and phone firmware version. For example, for Xiaomi Watch S3 s Wear OS A different approach will be required than for the fitness bracelets of the series Mi Band. We will cover all the main scenarios, and also give recommendations on optimizing the connection for stable operation.
1. Preparing devices before connecting
Before you begin synchronization, make sure that both devices are ready for the process. This will save you from most problems at the pairing stage.
Start by checking battery charge on your smart watch. The minimum level for a successful connection is 20%, but it is better if it is higher 50%. For some models (for example, Xiaomi Watch S1 Pro), when the battery is low, it may automatically turn off Bluetooth, which will interrupt the process. Also make sure that Bluetooth and geolocation are turned on on your phone (the latter is needed for the correct operation of some functions, such as weather or GPS tracking).
It is equally important to update the software on both devices. On your phone, check that the version is up to date Android in the section Settings โ System โ System update. For watches, update the firmware through the proprietary application (more on this in the next section). If you use Xiaomi based on Wear OS (for example, Watch 2 Pro), update the firmware via Play Market on the watch itself.
Download your smartwatch to 50% or higher
Turn on Bluetooth and geolocation on your phone
Update Android to the latest version
Make sure your phone has enough free memory (minimum 500 MB)
Reboot both devices before connecting -->
Pay special attention permissions on the phone. Modern versions of Android (since Android 10) require explicit confirmation of access to:
- ๐ฑ Contacts (for displaying incoming calls)
- ๐ Geolocation (for GPS and weather widgets)
- ๐ Storage (for downloading branded watch faces)
- ๐ Notifications (for synchronizing messages)
If you have a phone with shell MIUI (for example, Redmi Note 12 or POCO X5), before connecting, disable the function Battery optimization for the application Mi Fitness or Wear OS. This will prevent automatic shutdown of background processes that are necessary for stable synchronization.
2. Selecting and installing the right application
One of the most common sources of errors is using the wrong application for connection. Xiaomi smart watches are produced on different platforms, and each requires its own software:
| Watch model | Platform | Android application | Download link |
|---|---|---|---|
| Mi Band 3/4/5/6/7/8, Smart Band 7 Pro | Propietary OS | Mi Fitness (formerly Mi Fit) | Play Market |
| Xiaomi Watch S1/S2, Watch Color 2 | Propietary OS | Mi Fitness | Play Market |
| Xiaomi Watch 2 Pro, Watch S3 | Wear OS | Wear OS by Google | Play Market |
| Xiaomi Mi Watch (first generation) | Wear OS (outdated) | Wear OS by Google + Mi Wear | Play Market |
Important: For models on Wear OS (for example, Watch 2 Pro), first install the application Wear OS by Google, and then connect the watch. Attempt to connect through Mi Fitness will lead to an error.
After installing the application:
- Launch it and register (or log in) through your account Xiaomi, Google or other supported service.
- Click on the add device button (usually the icon
+in the upper right corner). - Select your watch model from the list. If it is not there, update the application or check the compatibility on the official Xiaomi website data-i="118">๐ Reboot both devices. Xiaomi official website.

This error often occurs when you try to connect a watch to Wear OS via Mi Fitness. Solution:
1. Remove Mi Fitness.
2. data-i="133">3. Connect the watch through this application. Wear OS by Google.
3. Connect your watch via this app.
If the problem persists, check the compatibility of the watch model with your version of Android on the official website.
3. Step-by-step guide for connecting
Let's look at the process using the example of the most popular model - Xiaomi Mi Band 8 (similar for Mi Band 7/6 and Smart Band 7 Pro). For watches on Wear OS (for example, Watch 2 Pro) the instructions will be different - more on this in the next section.
Step 1. Turn on the smart watch, holding down the power button (or touch area if there is no button) for 3-5 secondsuntil the logo appears Mi.
Step 2. Open the application Mi Fitness on your phone and press Add device. Select your model from the list.
Step 3. A QR codewill appear on the watch screen. Point your phone camera at him through the app. If the QR code does not scan:
- ๐ฆ Increase the brightness of the watch screen to maximum.
- ๐ธ Wipe the phone camera - dirt or scratches may interfere scanning.
- ๐ Reboot your watch and try again.
Step 4. After successful scanning, confirm pairing on both devices. A request for permission may appear on your phone access to notifications โbe sure to agree.
Step 5. Wait for data synchronization to complete (usually takes 1-3 minutes). At this stage, the watch may reboot - this is normal.
If at the synchronization stage the process freezes at 0% or 100%, check the Internet connection on your phone. The application Mi Fitness downloads the latest firmware data, and without a network this process will not be completed.
For models on Wear OS (for example, Xiaomi Watch 2 Pro):
- Install the application Wear OS by Google.
- Turn on the watch and select language.
- On your phone, open Wear OS and press
Set up device. - Confirm the code that appears on the watch.
- Select account Google for synchronization.
- Wait for the updates to install (may take up to
10-15 minutes).
4. Setting up basic functions after connection
After successful pairing, you need to configure key functions to ensure your watch performs as efficiently as possible. Let's start with the most important thing - notifications.
In the application Mi Fitness (or Wear OS for the corresponding models) go to the Notifications section and enable the option Show notifications. Here you can choose which applications will display alerts on the watch. For example, you can leave only WhatsApp, Telegram and Callsto avoid overloading the screen.
Next set activity tracking:
- ๐ Pedometer: Set a daily goal (recommended
8000-10000 steps). - ๐ค Sleep: Turn on automatic sleep tracking and set an alarm clock according to sleep phases.
- ๐ด Workouts: Add frequently used sports (running, cycling, swimming) to favorites.
- โค๏ธ Pulse: Set the measurement frequency (for example, every
10 minutesin the daytime and1 time per hourat night to save battery).
For models with GPS (for example Xiaomi Watch S3 or Smart Band 7 Pro) activate this function in the training settings. This will allow you to track the route without your phone, but remember that GPS significantly reduces battery life.
If you use the watch for swimming, before your first workout in in the pool, turn on the mode Water resistance in the settings. This will lock the touch screen and prevent accidental presses.
Don't forget about watch faces. More Mi Fitness more available 100+ free options are available, and for Wear OS you can install dials from Play Market on the watch. To save battery, choose watch faces with minimal animation and a dark theme (for AMOLED screens).
5. Troubleshooting common problems
