Modern wearable gadgets have become an integral part of the smart home and digital health ecosystem, and Xiaomi Mi Band 4 is rightfully considered one of the most popular devices in this segment. Despite the release of newer models, the fourth generation of the tracker remains relevant due to its excellent balance of price, functionality and battery life. Correctly setting up the device on the operating system Android is a critical step that determines the stability of receiving notifications and the accuracy of physical activity tracking.
The initial initialization process may seem confusing for beginners, especially given the need to install specialized software and grant a wide range of permissions to the system. Errors at the pairing stage often lead to the bracelet not receiving messages from instant messengers or incorrectly counting steps. In this material, we will analyze in detail every step, from unpacking to fine-tuning the sensors, so that your device works as efficiently as possible.
Before starting the procedure, make sure that your smartphone is charged at least 50%, and the tracker itself has a sufficient level of energy. Although Mi Band 4 often comes with a factory charge, it may not be sufficient for the initial synchronization process and firmware update. Also make sure you have a stable internet connection as the app will require you to download the latest training profiles and language packs.
Preparing the smartphone and installing the Mi Fit application
The foundation for the successful operation of the bundle Android and Mi Band is a correctly installed companion application. Previously, the main tool was the application Mi Fit, however, in the latest versions of the Xiaomi ecosystem there is a gradual transition to the application Zepp Life (previously known as Mi Fit). For users Mi Band 4 both options remain working, but the interface and operating logic may differ slightly. It is recommended to download software exclusively from the official store Google Play Marketto avoid malicious modifications.
After installing the application, you must create an account or log in to an existing one. This is a mandatory requirement to synchronize data to the cloud and save training statistics. When you first start it, the system will ask for permission to access geolocation, contacts and notifications. Refusal to grant these rights will result in the inability of key functions, such as unlocking the phone with a bracelet or displaying the name of the caller.
It is important to note that for background synchronization to work correctly in the battery settings of your smartphone, you must disable power saving for the application Mi Fit or Zepp Life. Skin manufacturers such as MIUI, EMUI or OneUI often aggressively terminate background processes, which breaks the connection with the tracker. Android, such as MIUI, EMUI or OneUI, often aggressively terminate background processes, which breaks the connection with the tracker.
⚠️ Attention: If you have previously used the bracelet with another phone, be sure to perform the Unpair procedure in the old application before attempting to connect to a new device. An attempt to pair a busy bracelet without first resetting will result in a communication error.
☑️ Preparing for connection
Pairing process and primary synchronization
Direct connection of the device occurs through the app interface, and not through the standard menu Bluetooth settings Android. This is a common user error: if you try to pair the bracelet through the phone's system settings, the application will not be able to detect the device and will give a search error. The algorithm of actions is strictly regulated by the developers to ensure the security of data transfer.
Launch the application and go to the tab Profile in the bottom menu. Click on the button Add device and select a category Bracelet. Find Mi Smart Band 4in the list of available models. After selection, the broadcast scanning process will begin. At this moment, a vibration or Bluetooth icon may appear on the tracker screen, confirming the search mode.
As soon as the application detects the device, a request to confirm pairing will appear on the smartphone screen, and a vibration will appear on the bracelet screen signal and graphic confirmation symbol. You need to tap on the icon on the tracker screen to complete the handshake of communication protocols. After a successful connection, automatic synchronization of time and basic settings will begin.
If the application takes a long time to search for the bracelet, try restarting Bluetooth on your smartphone or restarting the application itself without closing it completely from memory.
In some cases, especially on smartphones with custom firmware, you may need to manually enter a confirmation code. The system will generate a four-digit code on the phone screen, which you will need to dial on the touch screen Mi Band 4. Input accuracy is critical: three errors in a row can temporarily block a pairing attempt.
Setting up notifications and data display
One of the main reasons for buying a fitness tracker is the ability to receive notifications about calls and messages without taking your phone out of your pocket. In the application Mi Fit this section is in the menu Profile → Mi Band 4 → Application notification settings. Here is an extensive list of apps installed on your smartphone, checkboxes opposite which activate the transmission of push notifications.
For this function to work correctly in the system Android you must grant the companion application the right on Access to notifications. Usually, when you first turn on the switch in the bracelet settings menu, the system automatically redirects you to the appropriate security settings section Android. If this does not happen, find the section Accessibility or Notifications in your phone settings and activate the permission manually for Mi Fit.
- 📞 Incoming calls: Allows you to see the contact number or name, as well as reject the call by vibration of the bracelet.
- 💬 Messengers: Support for WhatsApp, Telegram, Viber and other popular services for displaying message text.
- 📧 Mail and social networks: Alerts about new letters and likes on social networks, which can be filtered.
Text length restrictions should be taken into account. The screen Mi Band 4 has a resolution of 120 × 240 pixels, so long messages will be cut off or require scrolling with a swipe. In addition, emoji may appear incorrectly or as squares if the device font does not support a specific Unicode character.
Sensor calibration and training setup
The accuracy of heart rate measurement and step counting directly depends on the correct wearing of the device and the entered anthropometric data. In your user profile, be sure to include your height, weight, date of birth, and preferred hand (left or right). These parameters are used by algorithms to calculate calorie consumption and step length.
The heart rate sensor Mi Band 4 works in automatic mode, but the measurement frequency can be adjusted. In the menu Heart rate settings the following options are available: 1 minute, 5 minutes, 10 minutes, 30 minutes or Off. The more often measurements are taken, the higher the accuracy of the statistics, but the faster the tracker’s battery power is consumed.
For sports fans, it is important to configure the order in which training modes are displayed. The bracelet supports swimming, running, cycling, walking and gym. You can change the order of the icons in the workout menu, choosing the most frequently used activities first. This will save time when starting activity recording.
| Parameter | Optimal value | Impact on work |
|---|---|---|
| Pulse rate | 5-10 minutes | Balance of accuracy and autonomy |
| Wrist lift | On | Automatic screen turn on |
| Vibration | Medium/High | Guaranteed visibility of notifications |
| Goal step by step | Individually | Motivation and activity analysis |
Function Raise your wrist to turn on the screen requires separate calibration. If the screen lights up too early or late, you can select your dominant hand in the settings and adjust the sensitivity. This will prevent false positives when gesturing during a conversation.
Updating firmware and changing watch faces
The tracker software is periodically updated by developers to fix bugs and add new features. When connecting for the first time, the application usually prompts you to update the firmware Firmware. The update process is critical: interruption of data transfer can lead to device failure. Make sure that the bracelet is near the phone and the charge level is above 20%.
One of the most popular features Mi Band 4 is support for color watch faces. There are thousands of screen designs available in the Theme Store, from minimalistic clocks to animated images. Installation of a third-party dial occurs through the app: select the design you like and press Synchronize. The download process may take from 30 seconds to 2 minutes depending on the file size.
⚠️ Attention: While updating the firmware or downloading the watch face, do not open other applications on your smartphone or lock the screen. Interrupting the process of writing to the bracelet's memory may require service repair.
What to do if the watch face does not install?
If the download freezes at 99%, try deleting the application and installing it again, after clearing the cache. Also check if the bracelet's memory is full of old themes.
It is worth remembering that complex animated watch faces consume significantly more power than static images. If your priority is maximum battery life (up to 20 days), choose simple black themes with a minimum number of elements.
Solving common problems and resetting settings
During operation, situations may arise when the bracelet stops synchronizing, does not vibrate with notifications, or displays the time incorrectly. The first step in diagnostics is always to reboot both devices: turn off and on Bluetooth on the phone, and reboot the bracelet through the menu Settings → System → Reboot.
If the problem is software in nature and cannot be resolved by rebooting, a full reset to factory settings may be required. In the application, this is done through the item Unlink in the device profile. After this, the bracelet returns to its “out of the box” state and requires repeating the pairing procedure. All accumulated data for the current day may be lost if synchronization has not been completed.
A common problem on Android is the lack of notifications after updating the phone system. This is due to the fact that new versions Android tighten background policies. You need to re-check the application permissions Mi Fit in the section Applications → Permissions and make sure that access to notifications is active.
In 90% of cases, connection problems are solved by completely unlinking the device in the application and repeating the pairing procedure rebooting the smartphone.
For advanced users, it is possible to install custom firmware through third-party utilities, however, this will void the device’s official warranty and can lead to unstable operation of the sensors. For most users, the functionality of the stock firmware is more than enough.
FAQ: Frequently asked questions
Can I use Mi Band 4 without a smartphone?
Yes, the bracelet can work autonomously as a watch and pedometer. However, to set the time, view detailed statistics and receive notifications, a connection to a smartphone is required. Training data is saved in the device’s memory and synchronized the next time it is connected.
Why doesn’t the bracelet count steps when I push the stroller?
The step counting algorithm is focused on the vibrations of the hand when walking. When pushing a stroller or cart, the hand remains motionless, so the steps are not recorded. To accurately record in such situations, it is recommended to temporarily attach the bracelet to your shoes or use the “Walking” training mode, which uses other analysis algorithms.
Is Mi Band 4 compatible with iOS (iPhone)?
Yes, the device is fully compatible with the iOS operating system version 9.0 and higher. The setup process is similar: you need to download the Mi Fit or Zepp Life application from the App Store. The functionality is almost identical to the version for Android, with the exception of some system integrations.
How to change the interface language on the bracelet?
The interface language Mi Band 4 depends on the system language of your smartphone. If the phone is set to Russian, the bracelet will automatically switch to Russian when synchronizing. There is no separate language setting in the bracelet menu.
