Modern wearables have become an integral part of the lives of many users who want to control their physical activity and health. Xiaomi Mi Band 4 is deservedly considered one of the most popular fitness trackers on the market due to its functionality and affordable price. However, the initial setup of the device can seem difficult for beginners unfamiliar with the ecosystem of smart devices of the Chinese manufacturer.
Synchronization requires a sequence of actions, the disruption of which often leads to connection errors. In this article, we will discuss in detail how to properly prepare the smartphone and the bracelet for the first launch, you will learn about the intricacies of the Mi Fit application (now Zepp Life) and how to fix common technical problems.
Successful pairing will allow you to access notifications, sleep monitoring, heart rate and multiple dials. It is critical to make sure that at least 20-30% of the battery is charged on the bracelet before starting the procedure, because in the process of updating the firmware, which often happens immediately after you connect, the device may run out. Let's move on to practical steps of setting up.
Preparation of the smartphone and checking system requirements
Before trying to connect devices, you need to make sure that your mobile phone is compatible. Xiaomi Mi Band 4 supports Android operating systems version 4.4 and higher, as well as iOS version 9.0 and later. If your smartphone was released earlier than these years, stable operation of the tracker is not guaranteed, and functionality may be limited.
The most important component for communication is the Bluetooth module. Make sure it is activated in your phone settings. Often users forget that the tracker requires not only Bluetooth enabled, but also GPS permission, since Android scanning devices is tied to geolocation services.
- 📱 Check the version of the operating system in the section "About the phone».
- 🔋 Charge your fitness bracelet to at least 50% before first synchronization.
- 📡 Activate Bluetooth and geolocation (GPS) in the quick settings of the smartphone.
- 📶 Make sure you have a stable internet connection to upload profiles.
⚠️ Warning: If you’ve previously used Mi Band 4 with another account, be sure to remove the device from your old profile in the app, otherwise the new phone won’t see the tracker.
It’s also worth freeing up some memory in the phone’s storage, as the bracelet management app takes up space and also caches your activity data. Before installing the software, it’s recommended to restart the smartphone to close the background processes that can block the search for new devices.
Installation and configuration of the management application
The Xiaomi Mi Band 4 requires specialized software. Mi Fit has long been the main app, but the manufacturer has been moving users to the Zepp Life platform (formerly known as Mi Fit) recently. Both apps are functionally similar, but Zepp Life gets interface updates and new features first.
Download the application should be exclusively from official sources: Google Play store for Android or App Store for iOS. APK-files from unverified sites can cause the device to be infected with malicious code or the tracker to work unstable. Once installed, launch the application and register a new account or log in to an existing one using a phone number, email or social media accounts.
During the registration process, the system may request access to various functions of the phone, and for the fitness tracker to work properly, you must allow access to:
- 📍 Geolocation (for tracking routes and finding devices).
- 📞 Contacts and call logs (to display the name of the caller on the bracelet screen).
- 📩 Notifications (for synchronization of messages from messengers).
- 🏃♂️ Physical activity (for correct calculation of steps in the background).
After you log in, go to your profile and select a region. For users from Russia and CIS countries, it is usually recommended to choose the appropriate country or “Global” to ensure that the servers work with minimal latency. Incorrect choice of region can lead to long data synchronization or lack of certain functions.
The process of pairing the bracelet with Android and iOS
The process of adding a device to a Zepp Life or Mi Fit app looks identical across platforms, but there are nuances to the system resolutions. Open the app and go to the Profile tab. At the top of the screen, click on Add Device and select from the Mi Band 4 list.
The app will ask for permission to use Bluetooth — confirm it. Next, you will start looking for devices within range. To get the bracelet into pairing mode, you may need to unlock it (touch the touch button) if it is in sleep mode. Your device’s name will appear on your smartphone screen, usually the Mi Band. 4_XXXX.
Click on the device name to start, and the tracker screen will display a vibration signal and a confirmation icon (check or OK button), tap the touch area on the bracelet to confirm the connection, and then the Connected status will appear on the smartphone screen.
☑️ Checklist of successful connection
If the connection is successful, the application will offer to update firmware. This is an important step, since the factory version of the software often contains errors or does not support Russian. Wait for download and install updates without turning off the smartphone screen and not moving away from the bracelet.
Set up notifications and personalize the interface
Once synchronized successfully, you can have a wide range of settings, and first of all, you can set up notifications, and then you can find the "Application Notifications" or "Application Warnings" section of the device menu, and you can choose which programs will send messages to your wrist.
It is important to understand that Xiaomi Mi Band 4 does not allow you to respond to messages, but only displays their content. To correctly display the text in Cyrillic (Russian) in the bracelet settings must be set in Russian, and the application includes the option “Display application ID” (sometimes helps if Krakozabras come instead of text).
| Parameter | Description of function | Impact on the battery |
|---|---|---|
| Vibration. | Strength and duration of response | Average. |
| Wrist lifting | Activation of the screen when moving | High. |
| Sleep monitoring | Analysis of sleep phases at night | Low. |
| NFC (version of Global) | Payment and access on the subway | Low. |
Also in the Dials section, you can change the look of the screen. There are dozens of options available, from classic analog to sports with large numbers. Customization allows you to make the device unique by matching the style to suit your clothes or mood. Some dials show more data (weather, pulse), but consume more energy.
⚠️ Warning: Constantly activated heart rate monitoring (every minute) can reduce the battery life of the bracelet. 20 before 10-12 days.
Don't forget to set goals for steps and calories in your user profile. The app calculates customized recommendations based on your age, weight and height. Correct profile data is necessary for accurate calorie expenditure and sleep quality analysis.
Solving Connection and Synchronization Problems
Despite the simplicity of the procedure, users often face difficulties. The most common problem is that the smartphone sees the bracelet but cannot complete the pairing by issuing an error. 90% of the time this is because the device is already "captured" by another phone or profile in the app.
To solve this problem, you need to perform a complete reset of the bracelet. On the tracker itself, scroll through the menu to System (watch icon) and select Unbind. After that, the bracelet will return to the factory settings and become visible for search again. If the menu is not available, you can use the reset function through the application.
Secret method of dumping through the application
Another common reason is aggressive energy savings in Android shells (MIUI, EMUI, OneUI). The system can kill the application process in the background, causing the bracelet to lose communication. You need to go to the battery settings, find the Zepp Life application and set the "No Limits" or "Autostart" mode.
- 🔄 Reboot Bluetooth on your smartphone (turn off/on).
- 🗑️ Remove the device from the list of paired in the Bluetooth phone settings.
- 📱 Check for updates for the app itself in the store.
- 🔌 Connect the bracelet to charging if it has been lying idle for a long time (battery activation).
If nothing works, try installing an alternative harvester app, such as Notify for Mi Band, which often sees the device even when the official app is powerless and can forcefully reset the Bluetooth stack settings.
Additional features and hidden tracker capabilities
After a successful setup, the Xiaomi Mi Band 4 is transformed into a powerful health monitoring tool, and in addition to steps, it can track stress levels (PAI), analyze sleep phases, and even measure blood oxygen saturation (in newer versions of the firmware), which is available as in-app graphs.
One of the useful features is music control, which can act as a remote control for a music player on a smartphone, which is convenient during jogging, when the phone is in your pocket or on your belt, and you want to control the tracks without taking out the device, and the feature "Find the phone" is available, which makes the smartphone loudly ring.
💡
Use the Do Not Disturb feature on your schedule so that the bracelet doesn’t vibrate from notifications at night, but keeps track of your sleep.
The training mode is available for athletes. The bracelet supports swimming (waterproof 5 ATM), running, cycling and yoga. When the wrist exercise mode is activated, the touch screen (water and sweat protection) is blocked, and pulse and tempo data is recorded in a separate log for subsequent analysis.
💡
Regular synchronization (at least once a day) is necessary to reset daily statistics and correctly plot activity schedules in the application.
Owners of the version with NFC They may try to set up payment, but in Russia and many other countries, this functionality is not officially supported for cards of local banks, working mainly in China. NFC You can use it to unlock a smart lock or other smart home scenarios.
