Smart wearables have become an integral part of the smart home ecosystem, and the Xiaomi Mi Band 4 remains one of the most popular options due to its price-to-function ratio. However, to achieve its full potential, it must be paired correctly with a smartphone and properly configured basic parameters. Many users face difficulties already in the initial synchronization phase, unaware of the nuances of the Mi Fit application (now Zepp Life) and the system limitations of the Android and iOS operating systems.
A good initial setup is critical to the tracker’s long-term performance. Mistakes at this point can cause notifications to arrive late, the pulse meter to malfunction and the battery to run out faster than expected. In this article, we’ll take a closer look at how the bracelet is integrated into your digital life, focusing on the hidden settings and technical features of Bluetooth Low Energy.
Before you start taking action, make sure your smartphone meets the minimum requirements: Bluetooth 4.0 and higher, as well as the current version of the operating system. For Android, this is usually version 5.0 and higher, for iOS – 9.0 and higher. It is also important to charge the device at least 20-30%, since the initial synchronization process and possible firmware update can require significant energy consumption.
Preparation for interface and installation of software
The foundation of successful customization is the installation of the right software on a mobile device. Xiaomi uses its own application to manage its wearable gadgets, which acts as a bridge between the tracker and cloud services. At the moment, the main application remains Mi Fit, which in some regions is rebranded in Zepp Life, but functionally for Mi Band 4 they are identical.
Once installed, you need to register for a Xiaomi account or log in to an existing one. This is a must, because without authorization, the app will not allow you to add a new device. Account registration requires a valid phone number or email address. In some regions, when registering through a phone number, you may have difficulties with confirmation codes, so using email is often a more stable option. Don't ignore permission requests when you first start.
⚠️ Note: When installing the application, be sure to allow access to geolocation (GPS). On Android, this is critical because it doesn’t have the power on. GPS The system will not allow scanning of Bluetooth devices, and finding the bracelet will be impossible.
Special attention should be paid to permissions for the application itself. In addition to geolocation, you need to provide access to notifications, contacts and background work. If the operating system asks if the application can run in the background, answer in the affirmative, which ensures that data synchronization will occur automatically, even when the application is folded or the smartphone screen is turned off.
💡
Install the Zepp Life (Mi Fit) app before charging the bracelet, which will avoid situations where the device upgrades to a version that is incompatible with your version of the app.
The process of connecting Mi Band 4 to a smartphone
Once the software is ready, you can move on to physical pairing of devices. It is important to understand that the standard Bluetooth menu in the smartphone settings is not used for primary binding here. Trying to connect through the system settings of Android or iOS often leads to errors or malfunction of the gadget. The whole process is controlled exclusively through the interface of the Mi Fit application.
The algorithm must be strictly consistent. Open the app and navigate to the user profile. At the top of the screen, the device add button or plus icon is usually displayed. By clicking on it, you will launch a scanner that will start looking for compatible gadgets within Bluetooth range. At this point, a vibration or a request for pairing confirmation may appear on the bracelet screen.
- 📱 Turn on Bluetooth on your smartphone and make sure it’s visible to other devices.
- 🔋 Activate the tracker by touching the touch area so that it comes out of sleep mode.
- 🔍 In the app, select Add Device and wait for "Mi Smart Band 4" to appear".
- ✅ Confirm the pairing by pressing the vibration button on the bracelet itself if the appropriate icon appears.
The connection may require a firmware update, the system will determine the version of the software and suggest downloading current files. This process is strictly impossible to interrupt: power outage or loss of communication during a firmware update can lead to a complete failure (bricking).

Basic configuration of interface and language
Once successfully connected, the user is challenged to adapt the interface to their needs. By default, the device can offer English or the language chosen in the smartphone system, but often requires manual adjustment. The wristband menu is built on the touch control of swipes and taps, so it is important to adjust the sensitivity and order of display elements.
To change the language, you need to go to the bracelet profile settings in the Mi Fit app. There is the item "Language and time." Here you can choose Russian, which is critical for the correct display of notifications and menus. If the language in the app and on the phone is Russian, the bracelet must automatically switch, but sometimes you need to manually select. Also in this section, the time format (12 or 24 hours) and the date are configured.
Customizing the information displayed on the screen is a key aspect of personalization. You can choose which data will be displayed on the main screen when you raise your wrist. This can be time, steps, pulse or weather. Using the wrist lifting feature saves battery power, since the screen only lights up when you move accordingly.
| Parameter | Description | Recommendation |
|---|---|---|
| Language | Choosing a menu localization | Russian (for Cyrillic notifications) |
| Time format | 12h or 24h | 24h (standard for the Russian Federation) |
| Raising the wrist | Activation of the screen by movement | Turn on (saves battery) |
| Brightness | Display illumination level | Medium or Auto |
You should also keep your brightness set. In bright sunlight, the minimum brightness may not be enough for readability, and at night the maximum brightness will be blinding. You can set the average or use automatic adjustment if it is supported by the current version of the firmware. This section also sets up a screen timeout, the time it takes for the display to go out after activation.
How do you get English back?
Configure notifications and system functions
One of the main reasons for buying a fitness bracelet is the ability to receive notifications without having to constantly pull out the phone. However, to work this feature consistently, you need to configure access rights in the smartphone operating system. Simply turning on a switch in the Mi Fit application is often not enough, especially on Android 10, 11, 12 and later.
In the app, you need to go to Notifications and Widgets (or Application Notifications) and activate the right sources: calls, SMS, messengers (WhatsApp, Telegram, Viber) and social networks. It is important to understand that the bracelet broadcasts what comes into the curtain of smartphone notifications. If the notification did not arrive on the phone, it will not appear on the bracelet.
⚠️ Note: On smartphones Xiaomi, Huawei, Samsung and other brands with aggressive energy savings, you must manually add the Mi Fit app to the battery exclusion list and allow auto-start. Otherwise, the system will “kill” the synchronization process, and notifications will stop coming.
For iOS users, the situation is a little easier thanks to a stricter, but predictable notification system, just allow access in the Bluetooth system settings and in the app itself. However, if you use the Do Not Disturb feature on your iPhone, it should be synchronized with the bracelet so that it does not vibrate at night, which is located in the device profile in the "Do Not Disturb" section.
Music management and phone search are worth special attention. The music management feature allows you to switch tracks and adjust volume right from the wrist, but it only works with standard players or popular streaming services. The phone search feature makes the smartphone make a loud sound, which is useful when it is lost at home. You can activate these functions under the "Application settings" -> "Music management" and "Phone search".
Health monitoring and sports regimes
Xiaomi Mi Band 4 is equipped with an optical heart rate sensor and an accelerometer, which allows it to effectively monitor physical activity. To properly work these functions, you need to adjust the user’s personal data: height, weight, age and gender. These parameters are used by algorithms to calculate calorie expenditure and analyze sleep phases.
The app offers a variety of sports modes: running outside, running indoors, walking, cycling, swimming and ellipse training. Before starting workouts, it is recommended to select the appropriate mode in the bracelet menu or in the application. In swimming mode, the device locks the touch screen so that water does not cause false presses, and uses the waterproof body of the 5 ATM standard.
- 🏃♂️ Running: Uses GPS Smartphone for track construction and accurate calculation of pace.
- 🏊♂️ Swimming: Tracks the number of strokes and SWOLF, lock-in.
- 🚴 Bicycle: Analyzes speed and distance by working in tandem with a phone in your pocket.
- 🧘 Yoga/Exercise: Calorie expenditure based on pulse and duration of session.
Sleep monitoring works automatically. The wristband analyzes movements and pulses at night, determining the phases of deep and superficial sleep, as well as periods of wakefulness. To improve accuracy, it is recommended to wear the wrist tightly but not compressing it, and not to remove it overnight. Sleep data is synchronized when you open the application and allow you to plot the quality of rest.
💡
The accuracy of the measurements depends on the density of the sensor's attachment to the skin, and the weakened strap causes light to be released and the pulse readings to be distorted.
Advanced settings and personalization of dials
One of the most pleasing features of the Mi Band 4 is the ability to change dials. Standard options can get boring quickly, so the dial store in the Mi Fit app offers hundreds of options, from minimalist analog to complex digital with plenty of data. Some dials are paid, but free options are more than enough.
To install a new dial, go to the device profile, select Dial Settings (or Dial Store). After selecting the design you like, click "Install." The download process will take some time, since the file is transmitted over Bluetooth, at which point it is better not to touch the bracelet.
In the advanced settings, you can also activate the Do Not Disturb mode on a schedule, set your alarm (the vibration of the bracelet will wake you up softer than the sound of your phone), and turn on a reminder of a sedentary lifestyle. The latter feature is especially useful for office workers: the bracelet will vibrate if you have not moved for an hour.
An important aspect is resetting, and if the bracelet is not working properly, it is freezing or not syncing, you can make a full reset via the device menu or app, which will return all settings to factory settings, but will not delete the data from the Xiaomi account, since it is stored in the cloud.
