Xiaomi Mi Band 4 Connection to Android: Full Instruction with Error Solutions

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular wearables due to its combination of functionality and affordable price. However, even with such a simple gadget, the process of connecting to a smartphone can raise questions - especially if you encounter Xiaomi equipment for the first time. In this article, we will discuss not only the basic procedure for pairing with Android, but also the nuances that the manufacturer often does not say: from choosing the right version of the application to avoiding typical errors like “does not see the bracelet” or “constantly breaks the connection”.

It’s important to understand that the Mi Band 4 works through the proprietary Mi Fit app (or its alternatives like Zepp Life) rather than the standard Bluetooth protocols on Android. This means that simply turning on Bluetooth on your phone isn’t enough — you’ll need to set up permissions correctly, sync accounts and sometimes even manipulate the region of the device. We tested the instruction on smartphones with MIUI 14, Android 13/14 and pure Android One, so it’s relevant for most modern devices.

1. Preparation of the smartphone and bracelet for connection

Before you start pairing, make sure your Mi Band 4 and smartphone are ready for the procedure.

• 📱 Android Version: Android 5.0 is the minimum supported version, but Android 7.0 is recommended for stable operation+. Older versions may have trouble synchronizing notifications.
• 🔋 Bracelet charge: battery level should be at least 20%. with a lower charge, the Mi Band 4 can turn off during setup.
• 📶 Internet connection: on the smartphone must be enabled Wi-Fi or mobile Internet to download the application and update the firmware bracelet.
• 🔒 Permissions: Check that your phone is allowed to install apps from unknown sources (if you are not downloading Mi Fit from Google Play).

If your bracelet was purchased in China (CN version) and your smartphone is tied to a European region (or vice versa), you may have synchronization problems, which may require you to change region in your Mi Account settings or use workarounds, which we will discuss later.

⚠️ Note: If you have previously used the Mi Band 3 bracelet or another Xiaomi model, remove it from the Mi Fit app before connecting the Mi Band 4. Simultaneous use of several devices of the same line can lead to firmware conflicts.

2. Installation and configuration of the Mi Fit application

The official Mi Band 4 management app is Mi Fit (developed by Huami), but since 2023 Xiaomi has been actively moving users to a new Zepp Life app that integrates support for all wearable devices of the brand. We recommend using Zepp Life, since Mi Fit no longer receives updates for new features.

Download the application from the official source:

• 🌍 Google Play: Mi Fit or Zepp Life
• 📥 APK-File: If the application is not available in your region, download it from the APKCombo website (select the latest stable version).

After installation, follow the following steps:

1. Open the app and select the language (English or Russian is recommended, as some localizations may not have features).
2. Sign in with Mi Account (if you don't have an account, sign up). Use the same region as the bracelet!
3. In the main menu, click Profile → Add the device.
4. Choose from the Mi Smart Band 4 list (not to be confused with Mi Band 3 or Mi Band 5).

Critical detail: if the Mi Band 4 is not on the list of devices, upgrade to the latest version of the app or change the account region to Russia (or Global). In some versions of the Mi Fit, old bracelet models are hidden to "simplify the interface."

3. The process of pairing the bracelet with a smartphone

Now, let's get to the connection itself. Follow the instructions strictly by step.

1. Activate Bluetooth on your smartphone and place the bracelet next to you (no more than 10 cm away).
2. In the Mi Fit/Zepp Life app, click Connect and wait for the system to find the Mi Band 4. If the bracelet is not detected, click Update List or restart Bluetooth on your phone.
3. When the bracelet appears on the list, tap it. The bracelet should display a 6-digit code -- compare it to the code in the app. If the codes match, confirm the pairing.
4. Wait until the synchronization is complete (it can take up to 2-3 minutes).

Once successfully connected, the app will offer to update the bracelet firmware, and we recommend you to agree, as the new versions fix synchronization errors and add features (for example, support for additional dials), the update will take 5-10 minutes and require a stable Internet connection.
