Modern wearables have become an integral part of life, and the fitness bracelet from the Chinese giant is taking a leading position in popularity.The fourth-generation model, known as the Xiaomi Mi Band 4, offers a wide range of functionality for tracking health, but requires the correct initial configuration. Without a competent setup, the device will not be able to transmit data about the pulse, steps and sleep to your smartphone, which makes the whole process useless.
Many users are struggling with the first turn on, not understanding why the screen doesn't light up or why the phone doesn't see the accessory. Direct connection in the phone settings often leads to errors and inability to control the device.
In this guide, we will take a look at everything from unpacking to fine-tuning notifications, how to avoid the typical mistakes that beginners make, and how to make the most of your tracker’s capabilities, and calibrate and set the parameters correctly to provide the most accurate data on physical activity.
Primary activation and charging of the device
The first thing to do after removing the capsule from the box is to provide it with energy. Often gadgets are sold with minimal battery power, so connecting to the power source is a must before any manipulation. Use a complete charging cable that has a specific shape with two contacts.
Insert the tracker capsule into the recess of the strap so that the contacts match the projections on the charger. The vibrator will confirm the successful connection. The battery icon should appear on the screen showing the process of energy storage. If the screen is black, wait a few minutes, sometimes a deep discharge takes time to respond.
⚠️ Warning: Do not attempt to charge the device from powerful fast-charging power supplies for flagship smartphones. USB-computer port or adapter with a current of not more than 1A to avoid overheating of the lithium polymer battery.
Once the Mi Band logo appears on the display, you can go to the software part. Make sure that your phone has Bluetooth on. It is through this wireless protocol that data is exchanged between the wearable gadget and the mobile device. Without active Bluetooth, finding the device in the application will be unsuccessful.
- 🔋 Check the integrity of the contacts on the capsule and charging before connecting.
- 📱 Make sure your smartphone has Bluetooth and geolocation enabled (GPS).
- ⚡ Do not leave the device on charge longer than necessary after reaching 100%.
💡
To extend the battery life, try not to discharge the device to zero. It is optimal to put the tracker on charging when there is 15-20% of energy left.
Installation and registration in the Mi Fit application
The main control center for your bracelet is the Mi Fit app (in new versions may be called Zepp Life), which stores the entire history of your activity, adjusts the dials and updates the firmware. You can download the program from the official Google Play stores or the App Store on request.
Once installed, launch the app and create a Xiaomi Account, a requirement for the brand’s smart home and wearable electronics ecosystem, registration takes a couple of minutes and requires email or phone number input, and without authorization, the app’s functionality will be severely limited.
Once an account is created, click on the plus in the top corner of the home screen to add a new device. The system will prompt you to select the type of gadget from the list. Find in the Mi Band 4 list and click on it. The application will start scanning the space around for a signal.
Once the same confirmation codes appear on your smartphone screen and on your bracelet display, tap the tick on the tracker. This action confirms the pairing and creates a secure connection. From now on, your pulse and steps will start synchronizing automatically when you open the app.

Basic configuration of the profile and user parameters
To get calorie counting and sleep algorithms to work properly, you need to enter accurate anthropometric data. Go to Profile in the bottom menu of the app, which shows height, weight, age and gender, and these parameters directly affect the calculation of energy expenditure during exercise.
If you plan to use the tracker for professional sports or specific workloads, you can set your targets, like setting a 10,000-step-a-day bar or a sleep-time target, and the app will motivate you to achieve those goals through vibrational notifications.
The important thing is to set the time display. From the device menu, find the settings of the bracelet → Time format. Here you can choose the 12-hour or 24-hour format. This section also configures the interface language, which is especially true for global firmware versions.
⚠️ Note: If you change your weight in your profile, your calorie history will not be recalculated in the past days, and the changes will only come into effect for new records, so it is important to enter current data immediately.
Remember to activate the wrist lift function to turn on the screen, which allows you to see the time and notifications with a slight movement of your hand without touching the touch button, and the sensor sensitivity can be adjusted if the screen lights up too often or, conversely, with a delay.
- ⚖️ Weigh before setting up to enter the exact weight for calculations.
- 🕒 Choose a convenient format of time (AM/PM or 24smack).
- 🌙 Set up the "Do Not Disturb" mode for night time.
Managing Notifications and Calls
One of the main functions of Xiaomi Mi Band 4 is to display notifications from your smartphone. In order for them to come to your wrist, you need to give the appropriate permissions in the application. Go to the device profile, select Application Notifications and activate switches for the desired programs: messengers, social networks, email clients.
It is also important for Android users to allow access to notification history in the phone’s system settings. Without this permission, the app will not be physically able to read incoming messages and transmit them to the wristband. On iPhone, notification management takes place through the Bluetooth system menu and the settings of the Mi Fit app itself.
Special attention should be paid to the setting of calls: you can turn off the vibration when you call in if you are in the movie, or, conversely, turn on only vibration by turning off the phone sound, this is implemented through the Assistive Touch function or the standard call settings in the tracker menu.
Why aren't the notifications coming?
You can customize the caller's name, if the contact is saved in the phone book of your smartphone, the brazlata screen will display the name, if the number is unknown, you will only see numbers, and you may need permission to access the phone book to work properly.
Set up training and health monitoring
The fitness tracker supports many activity modes: running, walking, cycling, swimming, etc. Before starting a class, select the appropriate mode in the Training on the bracelet menu or run it through the application, which will allow you to keep separate statistics for each type of load.
To measure your heart rate accurately, you need to snugly fit the strap to your wrist, but not squeeze your hand. The PPG (optical) sensor works by translucenting the skin with an LED. If the strap is dangling, the sensor will read the noise, not the actual heart rhythm, which will distort the data about the heart zones.
You can set up sedentary reminders in the app, if you haven't moved for an hour, the bracelet vibrates gently to remind you of your warm-up, and you can also use sleep monitoring, which is automatically activated when you go to bed and are still, and the accuracy of this mode depends on the correct timing and date.
☑️ Checking before training
The sleep phase analysis (deep, light, REM) is available in the app the day after waking up, and based on this data, the system can make recommendations for improving rest quality, and regular monitoring helps identify and correct problems with the daily routine.
Solution and firmware update
Periodically, the manufacturer releases software updates that add new dials or fix errors. You can check for an update in the device profile in the application. If the Update button is active, it is recommended to install a new version for stable operation.
A common problem is time desynchronization. If the watch on the wristband runs away or lags, manually sync it by pulling the app screen down. Time and date are taken from your smartphone, so it's important that the phone automatically adjusts the time over the network.
⚠️ Note: During the firmware update (OTA) Do not step far from your phone or close the Mi Fit app. Interrupting the process can cause the capsule software to break down.
If the bracelet has stopped responding to touch, try rebooting. In the settings menu on the tracker itself, find System → Reboot (or Reboot), which often solves problems with the interface freeze or sensor failure.
💡
Regular synchronization with the application is the key to accurate data and the correct operation of all functions of the smart bracelet.
If you lose all communication with your phone when you can't see it in Bluetooth, you may need to completely reset the bracelet, then you clear all the settings and you repair it again as a new device, which is a radical but effective method of solving software glitches.
