Once activated, the watch will automatically scan the surrounding space for available devices. If your smartphone with Mi Fitness (or Zepp Life for the global version) installed is nearby, a pairing notification will appear on the phone screen.

2. Connection with the phone: step-by-step instructions

Turning Bluetooth on is only half the story. If a watch is to sync data to a phone, receive notifications, or control music, it needs to be paired properly. Consider the process of using an Android smartphone (the logic is similar to that for an iPhone, but with nuances).

Step 1: Installation of the official annex

Without Xiaomi, the watch will not be able to fully interact with the smartphone.

• 📱 Mi Fitness – for Chinese firmware (available from APKMirror or official Chinese stores).
• 🌍 Zepp Life is a global version for European, American and Russian users (available in Google Play and App Store).
• 🔄 Xiaomi Wear – a universal app for new models (can support Watch 3 after the update).

Step 2: Connect via the application

After installing the program, follow the following steps:

1. Open the app and sign up (or sign in to your existing Xiaomi/Zepp account).
2. Press the badge "+" or "Add device" in upper right corner.
3. Select from the list of Xiaomi Watch 3 (if there is no model, update the app).
4. Follow the instructions on the screen – the system will prompt you to turn on Bluetooth on your phone and watch.
5. Confirm pairing on both devices (the clock will be a request with a confirmation code).

Step 3: Set up permits

After pairing, the application will request access to:

• 📱 Contacts – to display incoming calls.
• 📁 Files and Media – for Music Management.
• 📍 Geolocation – to accurately track activity.
• 🔔 Notifications – to display messages from messengers.

We recommend that you allow all requests, otherwise some of the functions of the watch will be unavailable.

💡

If the clock is not determined by the app, try restarting both devices and then re-pairing, sometimes by temporarily shutting down Bluetooth on the phone for 10 seconds.

3. Connection to headphones and other gadgets

Xiaomi Watch 3 can work not only with a smartphone, but also with other devices that support the Bluetooth Low Energy protocol (BLE). For example, you can connect wireless headphones to listen to music or a fitness bracelet to synchronize health data.

How to connect headphones:

1. Turn on the pairing mode on the headphones (usually you need to hold the power button for 3-5 seconds until the indicator blinks).
2. On the clock, go to Settings → Connections → Bluetooth.
3. Select "Search for devices" or "Add new".
4. In the list, find the name of your headphones (like Redmi Buds 3 or AirDots) and tap them.
5. Confirm the connection if necessary.

Features of connection:

• 🎧 Headphones should support the profile A2DP audio transmission.
• 🔋 The charge level of the headphones should be at least 30%, otherwise the connection may be unstable.
• 📶 The distance between the watch and headphones should not exceed 10 meters (under ideal conditions).

If the watch doesn’t see the headphones, try:

1. Turn off and turn on Bluetooth again on the watch.
2. Reset the headphone settings (usually this is done with a long press of the on button).
3. Make sure the headphones are not connected to another device (such as a phone).

4.Bluetooth problems: causes and solutions

Even after successful pairing, users sometimes experience problems: the connection goes missing, the clock doesn't respond to commands or stops synchronizing data, and let's look at the most common problems and how to fix them.

Problem 1: Bluetooth is spontaneously shut down

If the module is deactivated without your participation, check:

• ⚡ Charge level – at a critically low charge (less than 10%), the watch turns off energy-intensive functions.
• 🔄 Power saving mode - in the settings of the clock (Battery) → Energy saving option can be activated Bluetooth switch off in the background.
• 📱 Phone Settings – Some manufacturers (such as Samsung or Huawei) aggressively optimize the background of applications, which leads to a connection break.

Decision:

1. Turn off the energy saving mode on the watch.
2. Add the Mi appendix Fitness/Zepp Life in the list of optimization exceptions on the phone (in battery settings).
3. Update the watch firmware and app to the latest version.

Problem 2: The watch is not detected by the phone

7. Frequent questions and myths about Bluetooth in Xiaomi Watch 3

There's a lot of rumors going around the wireless modules in smartwatches, and we're going to look at some of the most popular questions and misconceptions.

Myth 1: “Bluetooth in a watch must always be on to work properly.”

It's not. The only module you need is:

• Synchronize data with the phone.
• Receiving notifications.
• Controlling music or smartphone camera.

If you don’t need these features, you can safely turn off Bluetooth – the watch will show time, count steps and measure your pulse without connecting to your phone.

Myth 2: “A watch can only be connected to one device.”

Xiaomi Watch 3 supports multi-connection (up to 2-3 devices at a time). For example, you can sync them with your phone and tablet or connect them to your phone and headphones at the same time.

Myth 3: “Bluetooth in watches only works up to 1 meter away.”

The range depends on the protocol version and obstacles:

• 📏 Bluetooth 5.0 (used in Watch 3) – up to 40 meters in ideal conditions (direct visibility, no interference).
• 🏠 In a room with furniture and walls - the real range is 5-10 meters.
• 🚗 In motion (for example, when running), the connection can be interrupted at a distance of 3-5 meters.

💡

For maximum range, keep your phone in your pocket at belt level – this is the optimal position for a stable signal.
