Connecting smartwatches to the phone Xiaomi Redmi: full instructions from A to Z

Xiaomi smartwatches and fitness bracelets have long been an integral part of the brand’s ecosystem, but their first connection to a Redmi smartphone often raises questions among users. Despite the seeming simplicity of the process, many face synchronization errors, Bluetooth problems or a misunderstanding of which application to use for a particular model. This article will help you understand all the nuances from choosing the right software to setting up notifications and solving typical problems.

The feature of Redmi phones is their close integration with Xiaomi’s branded services, which simultaneously simplifies and complicates the connection process. For example, Mi Band 7 and Redmi Watch 3 require the Mi Fit app, while Amazfit models (part of the Xiaomi ecosystem) will need Zepp Life. We will analyze each scenario in detail, including hidden settings that the manufacturer does not always advertise.

It’s important to consider that the connection algorithm may vary depending on the version of MIUI on your Redmi. For example, MIUI 14 introduced additional application permissions that affect the stability of communication with wearable devices. If you’ve been updating your phone’s firmware, some steps may need to be adjusted, which we’ll talk about as well.

1.What app do you need to connect a watch to Redmi?

The choice of software depends on the model of your smartwatch or fitness bracelet. Xiaomi uses two main applications for managing wearable devices:

• 📱 Mi Fit — for most Mi Band devices (including Mi Band 8), Redmi Watch (1/2/3 series) and some budget smartwatches. Supports basic synchronization of health data and notifications.
• 🌐 Zepp Life (formerly Amazfit) – for Amazfit devices (such as Amazfit GTR 4 or Bip 5), as well as for some premium models Xiaomi Watch. Offers advanced training analytics and sleep monitoring.

To make sure you don't go wrong, check the official page of your model on mi.com or in the documentation. For example, the Redmi Watch 3 Active requires Mi Fit, while the Xiaomi Watch S3 runs through Zepp Life. Installing the wrong app will result in the phone simply not detecting the watch when searching.

Download the program only from official sources:

• 🤖 Google Play for Android;
• 🍎 App Store for iOS (if you use Redmi on your iPhone, yes, it’s possible!)

⚠️ Warning: Some users install APK- application files from third-party sites, risking running into modified versions with viruses. Xiaomi regularly updates Mi Fit and Zepp Life, adding support for new devices, so it is better to wait for the official release than to use pirated builds.

2. Step-by-step instructions: how to connect the watch to Xiaomi Redmi

Consider a universal algorithm, using the example of connecting Redmi Watch 3 via Mi Fit. For other models, the steps may differ slightly, but the overall logic remains.

Charge your watch to at least 50% | Make sure your phone is Bluetooth enabled | Update Mi Fit/Zepp Life to the latest version | Allow the app to access notifications and geodata

-->

Step 1: Enact the clock and activate the pairing mode

On most Xiaomi devices, you need to:

1. Press the button on the body (if any) for 3-5 seconds.
2. Or swipe up the screen and select Add the device (for touch models).
3. Wait for the QR- code or the flashing Bluetooth indicator to appear.

Step 2: Launching the application and scanning

Open Mi Fit (or Zepp Life) and:

1. Click Profile → Add the device.
2. Select your model from the list (e.g. Redmi Watch 3).
3. Hold the phone to the clock at a distance of up to 10 cm and wait for automatic detection.

Step 3: Confirmation of connection

A unique code (e.g., 1234) will appear on the watch screen, compare it to the code in the app on the phone and confirm the pairing. If the codes don't match, interrupt the process and re-search the device.

Step 4: Set up the main parameters

After successful connection, the application will offer:

• 📏 Enter personal data (height, weight, age) to correctly calculate calories.
• 🔔 Set up notifications (SMS, Calls, messengers).
• 🔋 Enable automatic data synchronization (recommended to save clock charge).

⚠️ Warning: If the watch is permanently off after you connect, check Redmi's power saving settings. Go to Settings → Applications → Mi Fit → Battery and turn off Battery Optimization. This will prevent the application from being forced to close in the background.

3. Solving typical connection problems

Even when following the instructions, Redmi users often encounter errors, and let's look at the most common ones and how to fix them.

If none of these things worked, try resetting your watch to factory settings.

1. In the app, go to Profile → Your device → Settings → Reset.
2. Or on the watch itself, find the Reset option (usually in Settings → System).

Important: once reset, all data from the watch will be deleted, including the training history. Backup in Mi Fit does not save user settings, so they will have to configurate again.

-->

4. Set up notifications and additional functions

Once you've successfully connected, you can customize the interaction of the watch with your phone.

Notifications

To receive alerts about calls, SMS and messengers:

1. In Mi Fit, go to Profile → Your Device → Notifications.
2. Turn on the Call Notification and Notifications from the apps switch.
3. Select the apps you want to see on your watch (such as WhatsApp, Telegram).

Controlling music

On most models (for example, Redmi Watch 3) you can control the playback of music on the phone:

• 🎵 Swipe through the tracks on the watch screen.
• 🔊 Adjust volume through physical buttons (if any).

To do this, in the settings of the clock, turn on the option Music Management.

Quick responses to messages

Some devices (e.g. Xiaomi Watch S3) support template responses to SMS directly from the watch.

1. Open Zepp Life.
2. Go to Profile → Smart Features → Quick Answers.
3. Add up to 10 templates (e.g., “I’ll call you back,” “I’m busy right now”).

⚠️ Warning: The quick response function only works for SMS and some instant messengers (like WhatsApp). Telegram or Viber will require manual input from your phone.

5. Compatibility of smart watches with different models of Redmi

In theory, all Xiaomi smartwatches are compatible with any Redmi smartphone, but in practice, there may be nuances.

• 📱 Redmi Note 12/13, Redmi 12/13: Full compatibility with all Mi Fit and Zepp Life devices. Supports Bluetooth 5.3, which provides a stable connection.
• 📱 Redmi 10/11, Redmi Note 10/11: Power saving mode may need to be turned off for the Mi Fit, otherwise the watch will shut down after 10–15 minutes of inactivity.
• 📱 Redmi 9/9A/9C: These Bluetooth 5.0 models may have data synchronization delays (up to 1 to 2 minutes).

To check the compatibility of a particular watch model with your Redmi, use the official tool from Xiaomi:

1. Go to the compatibility check page.
2. Enter the watch and phone model.
3. The system will show if all functions are supported (e.g. notifications, GPS- synchronization).

If your Redmi model does not support the latest MIUI (e.g. Redmi 8 on MIUI 12), some of the watch’s features may be limited, in which case custom firmware (e.g. Xiaomi.EU) will help, but this requires unlocking the bootloader and may be unwarranted.

6. How to update the firmware of the watch through Xiaomi Redmi?

Regular firmware updates add new features and fix bugs. The Redmi update process looks like this:

For devices on Mi Fit:

1. Open Mi Fit and go to Profile → Your Device.
2. If an update is available, a New firmware notification will appear.
3. Connect the watch to charging and confirm the installation.

For devices on Zepp Life:

1. In the application, select Profile → About device → Update firmware.
2. Follow the instructions on the screen. Don't turn off the watch from your phone until the process is complete!

The update can take 5 to 30 minutes depending on the model, and if the clock is interrupted during the upgrade, it may stop turning on, requiring a physical button reset (press for 15 to 20 seconds).

⚠️ Warning: Before updating the watch firmware, make sure that Redmi has enough free space (minimum 500MB) and a battery level above 60%.

7. Alternative ways of connecting (without official applications)

If you don’t want to use Mi Fit or Zepp Life, there are alternative methods to control your watch:

• 🔗 Notify & Fitness (for Mi Band): An open source app that supports notifications and activity monitoring without registering with Xiaomi.
• 🔗 Tools & Mi Band: Allows you to customize the vibrations, screen and even the watch firmware (for advanced users).
• 🔗 Gadgetbridge: A universal app for wearables, but requires manual configuration.

To connect via Notify & Fitness:

1. Download the app from F-Droid.
2. Turn on the developer mode on the clock (5 times tap the version number in Settings → About the phone).
3. In Notify & Fitness, select Add Device → Mi Band and follow the instructions.

Note that alternative apps may not support all of the original software features, such as Gadgetbridge doesn’t sync with Mi Cloud, and Tools & Mi Band doesn’t have sleep analytics.

8.Security: How to protect data when connecting a watch?

Smartwatches collect sensitive information about health, location and activity to protect this data:

• 🔒 Use a complex password for your Xiaomi account (linked to Mi Fit).
• 📵 Turn off geodata transmission if you do not use GPS- tracking (in the clock settings).
• 🔄 Regularly check which apps have access to Mi Fit data in Settings → Applications → Mi Fit → Permissions.
• 🗑️ Clear your activity history if you are selling or transferring a watch to another person.

If you connect a watch to Redmi via public Wi-Fi (such as in a cafe), use a VPN to encrypt traffic, which will prevent data from being intercepted during synchronization.

For a complete data reset from the hours before the sale:

1. In the Mi Fit app, untie the device from your account.
2. On the clock, reset through Settings → System → Reset settings.
3. Remove the app and clear the cache in Settings → Applications → Mi Fit → Storage.

⚠️ Warning: When using alternative firmware (e.g., Amazfit Mod), the risk of data leakage increases, often containing undocumented features that can transfer information to third-party servers.
