Modern health tracking gadgets have become an integral part of the lives of many smartphone users. The model Xiaomi Mi Band 4 remains one of the most popular devices due to its price-functionality ratio. However, the initial setup process often raises questions for beginners, especially when working with the operating system Android. Proper pairing is the first step to obtaining accurate data on heart rate, sleep and physical activity.
In this article we will analyze in detail all stages of connection, from downloading software to fine-tuning notifications. You will learn how to avoid common mistakes that lead to lost connections or incorrect operation of sensors. By following our instructions, you can quickly activate your tracker and start using all its capabilities.
Preparatory stage and installation of the application
Before you try to connect devices, you need to make sure that your smartphone meets the minimum system requirements. For stable operation Mi Band 4 requires an Android version of at least 4.4, as well as the presence of a module Bluetooth 4.0 or higher. Most modern phones support these standards, but on older models it may be difficult to detect the bracelet.
A key element of the Xiaomi ecosystem is a specialized application. Previously, the main tool was Mi Fit, but now the company is actively transferring users to the platform Zepp Life (formerly known as Mi Fit). In some regions the app Mi Fitnessis also used. For owners of the fourth version of the bracelet, Zepp Lifeis still considered the most stable option, as it guarantees full compatibility with all functions of the device.
⚠️ Attention: Do not try to connect the bracelet through the standard Bluetooth menu in the phone settings. Pairing must occur exclusively within the application, otherwise the device may be blocked for further connection.
Download the official application from the store Google Play. Avoid using third-party APK files from unverified sites, as they may contain malicious code or outdated software. After installation, launch the app and grant all requested permissions, including access to geolocation, which is critical for Bluetooth scanning to work on new versions of Android.
Before installing the application, make sure that at least 20% of the battery on the bracelet is charged. A completely discharged device may not respond to pairing attempts during the first minutes of connecting to charging.
Pairing process and data synchronization
After successful installation and authorization in the application (via your Mi, Google or Facebook account), you can begin direct connection. On the main screen of the application, find the "Profile" tab or the add device button. The system will prompt you to select the type of gadget from the list - in our case it is Amazfit Band 4 or Mi Smart Band 4.
To start synchronization, place the bracelet next to your smartphone. Press the button on the tracker's touch screen to wake it up and wait for the vibration icon or Bluetooth icon to appear. In the application, click the "Add Device" button. The search algorithm will automatically detect your gadget.
- 📱 Make sure that the phone screen is active and the application is running in the background.
- ⌚ The bracelet may ask you to confirm pairing - click the checkmark.
- 🔋 Keep the devices at a distance of no more than 1 meter from each other during settings.
The initialization process may take from 30 seconds to 2 minutes. At this time, encryption keys are exchanged and basic firmware is downloaded. If you see a progress bar, do not close the application or lock your smartphone screen. After completion, you will see the main dial of your tracker on the phone screen.
☑️ Checking successful connection
Setting up notifications and functionality
One of the main reasons for buying a fitness bracelet is the ability to receive notifications about calls and messages directly on your wrist. For this feature to work correctly, you need to configure the appropriate permissions in the application and on the Android system. Go to the device profile settings in the application Zepp Life and find the “Application Notifications” section.
Activate the switches for those apps from which you want to see notifications. These could be instant messengers, social networks or email clients. However, simply turning on checkboxes is often not enough. The Android system, especially in shells from MIUI, Samsung or Huaweiaggressively saves energy and can “kill” background processes.
| Notification type | Required resolution | Where to configure |
|---|---|---|
| Incoming calls | Access to phone | Android Settings → Applications |
| Messages (SMS) | Access to SMS | Android Settings → Applications |
| Messengers | Access to notifications | Accessibility / Notifications |
| Work in the background | Battery → Autorun |
For stable operation, it is recommended to pin the application in the list of recent tasks and prevent the system from limiting its background activity. Go to Settings → Applications → Zepp Life → Battery and select the “No restrictions” mode. This ensures that the connection between the phone and Mi Band 4 will not be interrupted arbitrarily.
Customization of dials and interface
Xiaomi Mi Band 4 offers ample opportunities for personalizing the appearance. Unlike previous models, a color AMOLED display is available here, which allows you to set bright and detailed watch faces. In the application, go to the “Dials” section, where you will have access to a store with thousands of design options.
You can choose a free option from the catalog or upload your own image from the phone gallery. After selecting a style, click the "Sync" button. The process of downloading graphics to the device takes some time depending on the complexity of the image and connection speed Bluetooth.
⚠️ Warning: Installing complex animated watch faces can significantly increase battery consumption. If autonomy is a priority for you, choose static images with a minimum of details.
You can also change the order in which widgets are displayed when you swipe across the bracelet screen in the settings. You can bring the heart rate monitor, weather or music controls to the forefront, making the use of the device more ergonomic. All changes are applied instantly after synchronization.
The secret of hidden watch faces
In some firmware versions there are hidden watch faces that can only be activated through third-party utilities on a PC by connecting the bracelet directly via an adapter. However, this may void your warranty.
Solving common connection problems
Despite the simplicity of the procedure, users sometimes encounter difficulties. The bracelet may not be detected, constantly loses connection, or does not transmit heart rate data. Often the problem lies in the Bluetooth cache or a software version conflict.
If the device is not found, try a full reset of the Bluetooth settings on your phone. Go to Settings → System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings. After restarting your phone, try to find the gadget again. Also make sure that the bracelet is not paired with another phone within range.
- 🔄 Restart both devices: the smartphone and the fitness tracker.
- 🗑️ Remove the device from the list of paired ones in your phone's Bluetooth settings.
- 📲 Update the application Zepp Life to the latest available version in the store.
If the bracelet is frozen and does not respond to presses, it can be rebooted forcibly. Place it on charge for 5-10 minutes, then hold down the touch button for 10-15 seconds until the logo Miappears. This is a soft restart that does not delete your data.
90% of connection problems are solved by completely removing the device from the application, clearing the application cache and repeating the pairing procedure from scratch.
Firmware update and device support
The manufacturer regularly releases updates for Mi Band 4, which fix bugs, improve sensor accuracy and add new features. You can check the availability of new firmware in the device profile in the application. If a new version is available, the system will prompt you to download and install it.
The update process is critical for stability. During installation, the bracelet screen will be turned off, and progress will be displayed only on the smartphone screen. Interrupting this process may cause the device to stop turning on (“bricked”).
⚠️ Attention: Never move away from the phone or lock the screen while the firmware is being updated. Make sure that the bracelet charge is at least 50% before starting the procedure.
It is worth remembering that support for the model is gradually decreasing as new versions are released. The functionality may remain the same, but compatibility with new versions of Android requires careful attention to energy saving settings. Follow the official news in the community Xiaomi.
If after the update the bracelet begins to discharge quickly, calibrate the sensors: walk 100 steps outside with GPS turned on on your phone to verify the data.
Why does the bracelet not vibrate with notifications?
Check if the Do Not Disturb mode is turned on on the bracelet itself or in the application. Also make sure that notifications are allowed in the phone settings for a specific application (for example, Telegram) and they are not hidden in the status bar.
Is it possible to connect Mi Band 4 to two phones at the same time?
No, the device only supports an active connection with one smartphone. To switch, you need to unpair the bracelet in the application on the first phone and pair it again on the second.
How to reset the bracelet to factory settings?
In the bracelet menu, find the “System” or “Advanced” section, then select “Reset”. Or do this through the app in the device profile by selecting “Delete device.”
Is the heart rate monitor on the Mi Band 4 accurate for sports?
For amateur fitness and monitoring at rest, the accuracy is sufficient. However, during interval training with sudden changes in heart rate, the optical sensor may have a delay of 5-10 seconds compared to chest-mounted heart rate sensors.
