Connecting Mi Band 4 to Xiaomi phone: full instruction with error solutions

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular wearables due to its combination of affordable price, long autonomy and wide functionality. However, many users face difficulties when connecting the bracelet to a smartphone for the first time - especially if both devices are from Xiaomi. In this article, we will discuss not only the standard synchronization procedure through the Mi Fit application, but also the nuances of working with phones on MIUI, typical errors (for example, "Device Can not be found" or "Connection is interrupted"), as well as hidden settings that will help to unlock the full potential of the Mi Band 4.

It is important to understand that the connection process can vary depending on the firmware version of the bracelet, the phone model (for example, Redmi Note 10 Pro vs Xiaomi 13 Ultra) and regional features (Chinese or global version of the Mi Band).We took all these factors into account and prepared a universal guide that will suit even inexperienced users. If you have already tried to connect the bracelet and got an error, skip the basic steps and go straight to the section "Problemss".

Requirements before connecting: what to check

Before you start syncing, make sure your phone and bracelet meet the minimum requirements, which will save you 90% of potential problems during the connection phase.

• 📱 Smartphone: any Xiaomi, Redmi or any other model POCO Android 5.0 and higher (Android 8.0 recommended)+ On iOS, the bracelet also connects, but the functionality will be limited.
• 🔋 Bracelet charge: at least 20%.At a charge level below 15%, the Mi Band 4 can automatically shut down during synchronization.
• 📲 Mi Fit app: latest version from Google Play or App Gallery. Chinese phone firmware may require Mi Fit from Xiaomi App Store.
• 🔄 Bluetooth: version 4.0 LE All Xiaomi smartphones since 2016 support this standard.

A critical note for owners of Chinese versions of the Mi Band 4 (XMSH08HM model): these devices are originally tied to Xiaomi China servers and may not connect to the global version of Mi Fit.

Also check if the phone is power-saving mode for the Mi Fit application. On MIUI, this is done in the battery settings (Settings → Battery → Application Selection → Mi Fit → No restrictions). Otherwise, the connection with the bracelet will break in a few minutes.

Installation and configuration of the Mi Fit application

The official Mi Fit app is the only legal way to connect the Mi Band 4 to a smartphone. Alternative programs (such as Amazfit or Zepp) do not support this bracelet model.

• 🌍 Global version: Google Play or AppGallery.
• 🇨🇳 Chinese version: only via Xiaomi App Store (requires an account with China region).

After installation, follow the following steps:

1. Open Mi Fit and click Sign up (or sign in to your existing Xiaomi account).
2. Indicate your country of residence – this affects the available features (for example, Mi Pay does not work in all regions).
3. In the Profile menu, check that the correct gender, age and height are indicated – these data are used to calculate calories and steps.
4. Allow all application requests: access to geodata (to track routes), notifications (to display messages on the bracelet), and contacts (to identify calls).

⚠️ Note: If you use two Xiaomi accounts (e.g. one for phone, one for bracelet), the data will not sync. Make sure to use Mi Fit and in your phone settings (Settings) → Xiaomi account: same profile is listed.

💡

If after registration in Mi Fit does not appear button add device, restart the application and check the Internet connection. Sometimes Xiaomi servers process new accounts for a long time (up to 5 minutes).

Connecting Mi Band 4 to the phone

Now, to the synchronization process itself, follow the instructions carefully, and even one step can fail.

1. Activate the bracelet: Press the Mi Band 4 touch button (under the screen) and hold for 3 seconds until the code to connect appears.
2. Add the device to Mi Fit: Open Mi Fit and press + in the upper right corner. Select Bracelet → Mi Smart Band 4. Confirm that the code on the bracelet screen matches the code in the application.

Synchronization of data:

Configuring notifications:

"Device profile → Notifications"

If the error "Cannot find the device" appears at the connection stage, follow the following steps:

Reset the bracelet (hold the button for 10 seconds)|Turn off/turn on Bluetooth on your phone|Remove the bracelet from the list of conjugate devices in Bluetooth settings|Try connecting through another app (e.g. Zepp Life)-->

⚠️ Note: On Xiaomi phones with MIUI 12+ Automatic Bluetooth Shutdown can be triggered to save power. To avoid this, add Mi Fit to the list of "Secure Applications" (Settings) → Battery → Secure applications).

Setup of the bracelet after connecting

After successful synchronization, we recommend you to immediately configure the basic parameters of the Mi Band 4 to avoid problems in the future.

Pay special attention to the setup of the dials. There are more than 50 dials in the Mi Band 4, but many require additional download via Mi Fit:

1. Go to "Device Profile → Dials".
2. Choose a category (sports, classic, animation).
3. Click on your favorite dial and wait for the download (can take up to 1 minute).
4. Confirm the installation on the bracelet by touching the screen.

There are specific problems, however: for example, MIUI 13/14 may have a conflict between the built-in Xiaomi device manager and the Mi Fit app.

1. Open "Settings → Connected Devices".
2. Find Mi Band 4 in the list and click "Forget the device".
3. Restart Mi Fit and repeat the connection procedure.

💡

On Xiaomi phones with MIUI 12.5+, the Mi Band 4 bracelet can be connected directly through the Settings → Bluetooth system menu, but Mi Fit is still required for full operation.

Solving common problems

Even with the right connection, users often encounter errors, and we have compiled solutions for the most common cases:

If none of the solutions worked, try resetting the bracelet to factory settings:

1. In Mi Fit, go to "Device Profile → Untie the Device."
2. Hold the touch button for 15 seconds until vibrations appear.
3. Reconnect the bracelet as you did when you first used it.

⚠️ Warning: After the bracelet is reset, all data (steps, sleep, exercise) will be deleted. If it is not synchronized with Mi Fit, it will be impossible to restore it.

Alternative applications for Mi Band 4

If the standard Mi Fit is not satisfied (for example, due to limited functionality or connection problems), you can use third-party programs. They offer advanced features, but require more rights and may be less stable.

• 📊 Notify & Fitness: Supports custom dials, advanced notifications and data export to Google Fit.
• 🔄 Mi Band Master: allows you to adjust the vibration for each contact separately and includes the “Do Not Disturb” mode on schedule.
• 🌐 Zepp Life: Official app from Huami (Made Mi Band), but with a different interface and additional health metrics.

When using alternative applications, consider:

• Some features (such as Mi Pay) only work in Mi Fit.
• Synchronization of data between different applications can be duplicated.
• To install custom firmware, you will need to unlock the bracelet (the risk of losing warranty).

💡

If you use Notify & Fitness, turn off automatic sync in Mi Fit to avoid conflicts. In Mi Fit settings, select "Device Profile → Data Sync → Manual."
