How to connect the bracelet Xiaomi Mi Band 4 to the phone: the full guide

Modern wearables have become an integral part of many users’ lives, and the Xiaomi Mi Band 4 remains one of the most popular fitness trackers on the market due to its value for money. However, after buying or resetting the settings, the first task for the owner is to correctly synchronize the device with the smartphone. The initial setup process can seem confusing due to many nuances, especially if you have previously used devices from other manufacturers or another version of firmware.

It is critical to use official software to successfully pair, as third-party apps often don’t have access to all of the tracker’s features. In this article, we’ll take a closer look at each step of connecting a smart bracelet, look at the differences in settings for Android and iOS, and provide solutions for the typical mistakes users encounter when trying to establish a connection.

Incorrect sequence of actions, for example, trying to pair directly through Bluetooth settings without using a proxy app, is the most common reason for failure. For Mi Band 4 to work properly, you first need to create an account in the Mi Fit app (or Zepp Life), and only then search for the device. Ignoring this rule leads to the fact that the tracker is not activated and remains in standby mode.

Preparation for interface: requirements and installation of software

Before you start the connection procedure, you need to make sure that your smartphone meets the minimum system requirements.The device must run on Android 5.0 or iOS 10.0 and higher, and also have an active Bluetooth 4.0 module or later.If the phone's software is outdated, the application may not install or work improperly, constantly breaking the connection with the bracelet.

The main management tool is the Zepp Life app (formerly known as Mi Fit), which can be downloaded for free from the Google Play Store or Apple App Store. In some regions, you may need to install an additional Mi Fitness app to activate advanced features, but for the fourth model of the gang, the classic Zepp Life app remains the most stable and functional solution. Once you install the program, you will need to register an account using a phone number, email address or social network profile.

It is also important to prepare the tracker itself: if it is new, remove the protective film from the contacts on the back side and put it on charging at least on the back. 10-15 Even if the indicator shows charge, calibrating the battery before first turning on will help avoid a sudden shutdown during the firmware or setting.

Before installing the app, make sure that geolocation services (GPS) are enabled on your smartphone, as this is a mandatory requirement for the Bluetooth device scanner to work in Android.

Step-by-step: connecting to Android and iOS

The synchronization process is almost identical for both operating systems, but there are slight differences in requesting permissions. After you log in to your account in the Zepp Life app, go to the Profile tab in the lower right corner of the screen. Here you need to select Add Device and find the Mi Smart Band 4 in the list of available gadgets. The application will request permission to use Bluetooth and geolocation - this is a must-see without which finding the device is impossible.

When the app starts searching, a list of available devices will appear on your smartphone screen. Select your bracelet from the list (usually marked as MI Band 4 or MI Band 4 XXXX, where XXXX — last four characters MAC-The tracker screen will display a vibration signal and a request for confirmation of pairing, represented by the tick symbol. Click on this tick by touching the touch area of the bracelet to confirm the action.

Once confirmed, the time and data synchronization process will begin, and firmware updates may also be required.Don't interrupt this process and keep devices no more than 1-2 meters apart.If firmware updates are not offered automatically, it's recommended to check it manually in device settings, as newer versions often fix Bluetooth connection errors and improve sensor accuracy.

iPhone owners should note that iOS strictly controls app access rights. If the bracelet does not display notifications after connecting, check the privacy settings in iOS itself: go to Settings → Mi Fit (or Zepp Life) and make sure that the Notifications switch is activated. Without this system permission, push messages from messengers and calls will not arrive on the wrist, even if the main connection is installed.

Configure notifications and functions in the application

Once you have a successful connection, you have a wide range of customization options available. From the device menu in the app, select "Application Notifications." Here you can flexibly configure which programs will transmit data to Mi Band 4. The standard list includes calls, SMS, as well as popular messengers and social networks such as WhatsApp, Telegram, VKontakte and others.

It is important to understand that the bracelet only broadcasts the text of the notification, it is not a standalone communication device. To work properly, the tracker application must have permission to work in the background, otherwise the phone's operating system may "sleep" and stop transmitting data to the clock. In the smartphone battery settings, find the Zepp Life application and set the "No Limits" or similar mode to prevent the forced closure of the process.

• 📱 Calls: allows you to see the caller’s number and contact name, and quickly defy vibration.
• 💬 Messages: displays text SMS and messages from messengers (up to) 30-40 symbols according to language).
• 🌤 Weather: synchronizes temperature and forecast data, requiring geolocation to be enabled.
• 🏃 Sport: setting goals by steps, pulse and choosing from 6 major sporting modes.

Problem Solving: Bracelet is not connected or lost

The most common problem users face is the inability to find a device or persistent communication breaks. If an in-app search does not yield results, the first thing you should do is reboot your smartphone and the tracker itself. Often errors accumulate in the memory of the phone's Bluetooth module that prevent new devices from being discovered. Also make sure that the bracelet is not connected to another phone or tablet, since the Mi Band 4 can only support an active connection to one gadget at a time.

⚠️ Warning: If you’ve previously used a bracelet with another phone, be sure to break the connection in the app on your old device or make a full reset (see section below), otherwise the new phone won’t be able to “friend” the tracker.

Another reason could be Bluetooth version conflict. Make sure your phone's Bluetooth settings don't have a saved MI Band 4 profile. If there is one, click "Forget Device" or "Unpair" and then repeat the application connection procedure. Direct pairing through Android or iOS system settings doesn't work for data transfer, it's only necessary for the initial handshake, which is better entrusted to the application's automation.

In some cases, cleaning the app cache helps. Go to Phone Settings → Apps → Zepp Life → Memory and click Clear Cache. This action will not delete your workout data, as it is stored on the server, but will reset temporary files that may have caused the communication module to malfunction.

Resetting settings and reconnecting the device

If the software methods don't work, or you're planning to sell the device, you need to perform a full reset. On the bracelet, swipe left to the More menu, find the gear icon or System item, and select Unbind or Factory Reset. Confirm the action, after which the tracker will return to the factory settings and be ready for the primary connection.

An alternative reset is available through the app. In your device profile, scroll down to the bottom and select Unbind. This action will break the connection to your Xiaomi account and clear the data on the bracelet. After that, you can link the device to a new account or a new phone. Remember that after reset, all accumulated step and sleep data that did not sync with the server will be permanently deleted.
