Modern wearables have become an integral part of the smart home ecosystem, and the Xiaomi Mi Band 4 remains one of the most popular fitness trackers due to its price-to-feature ratio.Proper initial device setup is critical to the stable operation of all features, including sleep monitoring, step counting and notifications. The pairing process may seem simple, but users often face difficulties in choosing an app or setting up access rights on the Android system.
In this article, we will take a look at all the steps of activating the tracker, from unpacking to first synchronizing data. You will learn about the differences between official companion apps, learn how to bypass common connection errors and understand how to configure notifications so that they actually come to the wrist.
Before you go to the software part, you need to perform basic hardware training. Make sure that your smartphone meets the minimum requirements of the Android operating system version (usually version 5.0 and above) and has a Bluetooth module on. It is also important that the tracker itself is charged at least 20-30%, as a discharged battery can prevent the successful completion of the pairing procedure.
Preparing a smartphone and choosing the right application
The first step in the process of integrating a gadget into your digital life is to install specialized software. For a long time, the main application for managing Xiaomi trackers was Mi Fit, but in recent years the company has rebranded, and now the main tool is the Zepp Life application.
Uploading the installation file should be done exclusively from official sources to avoid malicious code or unstable versions. For Android users, this is the Google Play Market store, where the application is distributed for free. After installation, take your time to open the program - you first need to create an account or log in through existing social networking or email profiles.
⚠️ Warning: Do not try to connect the bracelet directly through the standard Bluetooth menu in the Android settings.This will result in a pairing error and the device will become unavailable for the application until the bracelet settings are completely reset.
To register an account, you will need a valid email address or phone number. The system can request verification of identity through a code from a text message or letter. Once successful, the application will request access to geolocation, camera and notifications - all these permissions must be provided, otherwise synchronization will not work. Geolocation is necessary for correct tracking of routes, and access to notifications allows you to broadcast messages to the tracker screen.
It is important to note that for users from different regions, the interface and servers may differ. When registering, the system will automatically determine your region, but if you are traveling or using a VPN, the data may be stored on a remote server, which sometimes affects the speed of the application response.
The process of pairing the bracelet with the phone
Once the app is installed and the account is created, you can go to the direct connection of the devices. Turn on Bluetooth on your smartphone and make sure that it is visible to other devices. Run Zepp Life and go to the Profile tab, which is usually located in the lower right corner of the screen.
From the list of available gadgets, select the category “Bracelet” and find the Mi Smart Band 4 model. The application will switch to search mode, scanning the airwaves for signals from nearby devices. At this point, a vibration or a visual indicator of connection waiting on the tracker screen may appear, confirming that the device is ready for (mating).
When the smartphone detects the tracker, the device's name will appear on the phone screen, often containing the serial number or simply the model name. Click on it to start the procedure. The bracelet will have a request for confirmation of pairing, accompanied by a characteristic vibration. You need to touch the touch button on the tracker or swipe your finger to confirm the action.
☑️ Checklist of successful pairing
Once confirmed, the system will automatically synchronize time and date, and prompt a firmware update.firmware is the internal software of the tracker that manages all of its functions. Updating to the latest version is critical to fix bugs and improve battery life.
The upgrade process can take anywhere from 5 to 15 minutes depending on the version installed on the device at the time of purchase.At this time, the phone screen may go out, but the application will continue to work in the background.Do not turn off Bluetooth or delete the application from the phone's memory before the process is complete, otherwise the device may go into recovery mode or stop responding.
Configure access rights and permissions in Android
Android security, especially in versions 10, 11, 12 and later, strictly controls the background activity of applications. In order for the tracker to continuously transmit pulse and step data, as well as instantly display notifications, you need to manually adjust several critical parameters in the smartphone operating system. Without these settings, the communication between the phone and the bracelet will constantly break.
First of all, you need to allow the Zepp Life app to access geolocation, even if you don't plan to use it. GPS-Tracking of jogging, Bluetooth Low Energy Protocol (BLE) require GPS-module for stable device search. Go to Settings → Annexes → Zepp Life → Permissions and make sure that the "Geolocation" option is activated and the "Allow Always" mode is selected».
The second important step is to remove the application from power saving mode. Android tends to “kill” background processes to save battery power, which leads to loss of sleep data or missed calls on the bracelet. You need to find the battery settings for a particular application and choose the option “No limits” or “No saving charge”.
Check notification settings. In the app menu, find the Notifications section and activate the switches for the apps you want to see on your wrist (WhatsApp, Telegram, calls, SMS). Once activated, Android can request permission to “Access Notifications” – this must be confirmed.
⚠️ Note: On smartphones Xiaomi, Huawei and Samsung have aggressive algorithms for cleaning memory. it is recommended to additionally fix the Zepp Life application in the list of running processes (lock app) so that the system does not forcibly close it.
Some phone models may need to enable the app auto-start. Find the Auto-Start section in your phone settings and make sure the slider opposite Zepp Life is on, which ensures that the service starts immediately after the phone is turned on and waits for the bracelet to connect.
Customization of the interface and dials
One of the key features of the Mi Band 4 is the ability to change dials, which allows you to personalize the appearance of the device to your style or current activity. The application provides an extensive catalog of both free and paid dials. To download new design, go to the device profile and select “Dials”.
Choose your favorite design and click the "Install" button. The download process takes a few seconds, after which the image is automatically transferred to the tracker screen. In addition to ready-made solutions, some third-party applications allow you to create your own dials using personal photos or specific data sets displayed on the screen.
You can also adjust the order of the cards displayed in the display settings. You can swipe up or down between the pedometer, pulsemeter, weather and other widgets. In the app under Settings → Display settings, you can activate or hide unnecessary functions, as well as adjust the brightness of the screen and the time before it is quenched.
An important feature is setting the wrist lift to turn on the screen. You can choose time slots when this feature is active (for example, only during the day or only at night) to avoid accidental screen switching on while sleeping.

Table of main characteristics and capabilities
To better understand the device’s technical capabilities and what you’re setting up, consider the basic parameters of the Mi Band 4 compared to previous models, which will help you assess the scale of updates you get after connecting and syncing.
| Characteristics | Mi Band 3 | Mi Band 4 | Description of function |
|---|---|---|---|
| Screen. | Monochrome OLED | Colored AMOLED | A bright picture with saturated flowers |
| Permission | 128 × 80 pixel | 120 × 240 pixel | More clear display of text and icons |
| Water protection | 5 ATM | 5 ATM | Possibility of swimming in the pool at a depth of up to 50 meters |
| Music. | No. | Reproduction management | Switching tracks and volume on a smartphone |
| pulsemeter | Aye (basic) | Improved (6 sensors) | More accurate heart rate measurement and sleep monitoring |
As you can see from the table, the transition to a color display and an improved pulse sensor makes the fourth version a significant step forward, and the configuration of these functions through the application allows you to unlock their full potential, for example, the accuracy of the pulse measurement depends on the density of the sensor, which can also be tested in the application.
Solving common problems when connecting
Despite the fact that the process is fine, users may encounter technical difficulties. One of the most common problems is that the phone does not see the bracelet. In this case, you need to make sure that the device is not connected to another phone. Mi Band 4 can only be paired with one smartphone at a time. If the bracelet was previously used with another phone, it must be untie in the application on the old device or perform a reset.
Another common situation is the constant disconnection of the connection, which is often due to the peculiarities of Bluetooth in a particular phone model or the presence of interference. Try to restart the smartphone, turn off and turn on Bluetooth, and clear the cache of the Zepp Life application through the Android settings.
If the bracelet has stopped responding to commands or has frozen, a forced reboot will help. To do this, set the tracker to charge for 5-10 minutes. If this does not help, you can perform a full reset through the application (Profile → Mi Band 4 → Untie), then reconnect as with a new device.
💡
If the bracelet stopped syncing after an Android update, try uninstalling the app, restarting the phone, installing the app again, and re-associating the device, often addressing protocol compatibility issues.
In rare cases, the problem may lie in the hardware of the tracker itself, for example, the oxidation of the charging contacts or the rupture of the antenna inside the case. If the software methods do not help, and the bracelet is guaranteed, it makes sense to contact the service center.
💡
The stability of the bracelet depends on 90% of the correct settings of energy saving in Android and the availability of the current version of the firmware on the device itself.
