Modern wearable devices have become an integral part of the smart home and personal health ecosystem. The fitness bracelet Mi Smart Band 4 from the company Xiaomi remains one of the most popular gadgets due to its price-to-functionality ratio. However, many users encounter difficulties at the initial setup stage, especially if they have not previously used products from this brand. The pairing process requires compliance with a certain sequence of actions, ignoring which can lead to synchronization errors or the inability to register the device.
For a successful start, you will need not only the bracelet itself, but also a smartphone with an operating system Android version 5.0 and higher, as well as a stable Internet connection. The key element in this chain is the correct software, which acts as a bridge between the hardware of the bracelet and your account. In this article, we will go through each step in detail, from preparing your phone to fine-tuning notifications, so that you can get the most out of your tracker.
Before starting the procedure, make sure that wireless modules are turned on on your device. In particular, for work Mi Band 4 the module is critically important Bluetooth, which should be active and visible to other devices. It is also recommended to charge the bracelet to a level of at least 20% to avoid a sudden shutdown during the firmware or setup process, which can lead to software failures.
Preparing the smartphone and selecting the application
The first and most important step is to install the correct software. There are many clone apps on the Play Market that promise to support fitness trackers, but they are often unstable or contain malicious code. For Mi Smart Band 4 the official and only correct solution is the application Mi Fit (in some regions it may be called Zepp Life). Download it only from official sources to ensure the security of your personal data.
After installing the application, you need to create an account Mi Account. This is a mandatory requirement of the ecosystem Xiaomi, which allows you to store the history of your activity in the cloud and synchronize data between different devices. The registration process is simple: enter your phone number or email address, create a strong password and confirm the action with a code from SMS or letter.
⚠️ Attention: When registering, provide real data, since restoring access to your account without an associated number or email can become a complex procedure that requires contacting technical support.
In addition to the main application, for the bracelet to work correctly on Android, you need to grant special permissions to a number of system services. In modern versions of the operating system, starting from Android 6.0, access rights management has become more strict. You'll need to manually allow the app to access geolocation, even if you don't plan to use GPS tracking directly through the bracelet. This is due to the peculiarities of the protocol Bluetooth Low Energy (BLE), which requires access to the location to scan devices.
If the Mi Fit application does not see the bracelet when searching, try to forcefully stop the Bluetooth service in the phone settings and start it again, or simply restart the smartphone.
The pairing process and initial synchronization
When the preparatory stage is completed, you can proceed to directly connecting the devices. Launch the application Mi Fit on your smartphone and log in to the created account. From the main screen, select the "Profile" tab located in the lower right corner of the interface. Next, click on the “Add device” button and select “Bracelet” from the list of available categories.
Now take yours Mi Smart Band 4 in your hands. If it's new, it should automatically go into pairing mode, displaying a Bluetooth icon or vibration on the screen. If the bracelet was previously connected to another phone, you must first unlink it in the old application or reset it to factory settings through the menu of the tracker itself. Bring the bracelet as close to your smartphone as possible - the distance should not exceed 1-2 meters for a stable connection.
The application will begin scanning the surrounding area. As soon as the image of your bracelet with its unique identifier (usually the last 4 digits of the MAC address) appears on the phone screen, click on it to start (pairing). A request to confirm the connection will appear on the tracker screen. You need to tap the touch button on the bracelet to confirm the action. After this, the process of synchronizing time and basic settings will begin.
- 📱 Make sure that the smartphone screen is unlocked during the pairing procedure.
- 📶 Keep the devices next to each other until the profile settings are completely completed.
- 🔋 Do not allow the bracelet battery to discharge below 10% during the first turn on.
It is important to understand that pairing happens through the app, and not through the standard Android Bluetooth settings menu. If you try to connect the bracelet through the phone's system settings, you will see a success message, but the functionality of the device will remain unavailable and no data will be transferred. Always use the interface Mi Fit to manage the connection.
☑️ Check before connecting
Setting up a user profile and activity goals
After successful connection, the application will prompt you to set up a personal profile. This data is critical for correctly calculating calories burned, distance traveled and sleep quality. Algorithms Mi Band 4 use complex formulas depending on your weight, height, age and gender. Entering incorrect data will result in incorrect activity statistics, which will reduce the motivation and usefulness of the device.
In the profile settings section, you can also set daily goals. By default, the system suggests walking 10,000 steps per day, but this value can be adjusted up or down depending on your lifestyle and fitness. For office workers, a goal of 6,000 steps may be relevant, while for athletes the norm may be 15,000 or more. The bracelet will vibrate and show an animation on the screen when you achieve your goal.
| Parameter | Impact on calculations | Input recommendation |
|---|---|---|
| Weight | Calculation of calories and load on joints | Indicate current weight accurate to 0.1 kg |
| Height | Step length and energy consumption | Enter exact height without shoes |
| Date of birth | Calculation of maximum heart rate (MPR) | Check the relevance of the year of birth |
| Gender | Metabolic characteristics and sleep | Select the appropriate option |
Special attention should be paid settings sleep monitoring. In the application, you can enable advanced analysis of sleep phases, which will allow the tracker to record not only rest time, but also periods of deep and REM sleep. For this function to work, the bracelet must fit snugly to the wrist at night, but not constrict the blood flow. Sleep data is automatically synchronized when you wake up in the morning when you raise your hand.
How does calorie calculation work?
The algorithm takes into account the basal metabolic rate (BMR), calculated based on your anthropometric data, and adds to it active calories received during the movement recorded accelerometer and optical heart rate sensor.
Configuration of notifications and alarms
One of the main reasons for purchasing a fitness bracelet is the ability to receive notifications from a smartphone directly on your wrist without taking the phone out of your pocket. Mi Smart Band 4 supports displaying notifications from calls SMS, as well as popular instant messengers and social networks. To activate this feature, go to the application menu Mi Fit, select your bracelet and find the "Application Notifications" section.
Here you will see a list of all apps installed on your phone that can generate notifications. You need to manually turn on the switches next to those applications from which you want to receive messages on the bracelet. Please note that notification text is displayed on the tracker's small screen, so long messages may be cut off. For comfortable reading, it is recommended to use brief wording in the settings of the messengers themselves.
⚠️ Attention: On some smartphone models (for example, Huawei, Honor, Xiaomi with MIUI), the system may aggressively close background processes to save energy. This may cause notifications to stop arriving on the bracelet.
To solve the problem with missed notifications, you need to add the application Mi Fit to the list of power saving exclusions. Go to your phone settings, find the "Battery" or "Applications" section, select Mi Fit and set the operating mode to "No restrictions" or "Autostart". Also pin the application in memory so that the operating system does not unload it when clearing RAM.
In addition to notifications, the bracelet has a vibration alarm function. This is an extremely useful option for those who do not want to wake up others with sound or prefer a gentle awakening. You can set up to 5 different alarms directly in the application, specifying the days of the week and the alarm time. The alarm will only work if the bracelet is worn on the hand and recognizes a movement that simulates the owner waking up.
Health monitoring and sports modes
Mi Smart Band 4 equipped with an optical heart rate sensor that allows you to track your pulse 24/7 or in periodic measurements. In the app you can set the frequency of measurements: for example, every 30 minutes or only during training. Continuous monitoring allows you to build detailed graphs of heart rate changes throughout the day and identify anomalies, such as tachycardia at rest.
For sports, the bracelet has 6 main modes: outdoor running, indoor running, cycling, walking, swimming and free training. When you select a mode, the bracelet begins actively measuring your heart rate and calculating the parameters of a specific activity. For example, in swimming mode, the tracker takes into account the number of strokes and swimming style, thanks to its standard water resistance. 5 ATM.
Workout data is saved in the device’s memory and synchronized with the smartphone after the end of the lesson. In the application you can see a detailed route map (if you used your phone's GPS), pace, cadence and heart rate zones. Analyzing your heart rate zones helps you understand how effectively your workout was: whether you were burning fat or developing endurance.
- ❤️ To accurately measure your heart rate during sports, tighten the strap tightly on your wrist.
- 🏊♂️ After swimming in salt water, be sure to rinse the bracelet with fresh water.
- 🏃♂️ Use the "Outdoor Running" mode only if you have a connected smartphone with GPS.
It is worth noting that the wrist-based heart rate sensor has a certain error compared to chest-mounted heart rate monitors, especially during high-intensity interval training. However, for amateur sports and monitoring of general health, accuracy Mi Band 4 is quite sufficient. Regular measurements help track progress in training and the decline in resting heart rate over time.
Regular calibration of weight and height data in the profile improves the accuracy of calorie and distance calculations in the absence of GPS.
Additional functions and customization of the interface
One of the nice features Mi Smart Band 4 is the ability to change watch faces. The built-in library contains several dozen screen design options, from classic clocks to minimalist step indicators. You can change the watch face directly from the application Mi Fit in the "Bracelet Settings" ->"Bracelet Display" section. The selection is applied instantly after clicking the "Synchronize" button.
For advanced users, it is possible to install third-party watch faces through special utilities, although this requires some caution. Unofficial watch faces may consume more power or display data incorrectly. In addition, in the settings you can change the units of measurement (kilometers or miles), the time format (12 or 24 hours) and the interface language of the bracelet itself.
The "Find Phone" function also deserves mention. If you lose your smartphone within the apartment, just press the touch button on the bracelet for a few seconds. The phone will start ringing loudly even if it is in silent mode. This works thanks to two-way communication via protocol Bluetooth.
⚠️ Attention: The Mi Fit application interface is periodically updated by the developers. The location of some menu items may differ slightly from that described in the instructions. Always pay attention to icons and logical groups of settings.
Do not forget to regularly update the bracelet firmware. Developers release updates that fix bugs, improve sensor accuracy, and add new features. A notification about available firmware will appear in the application automatically. During the update, do not turn off Bluetooth and keep the phone near the bracelet so as not to interrupt the process of writing data to the device’s memory.
What to do if the dial does not change?
Make sure that the bracelet is charged more than 20% and is in an area of stable Bluetooth signal reception. Try restarting the Mi Fit application.
