Wearable electronics have long ceased to be just a toy for enthusiasts, turning into an indispensable assistant for tracking health and physical activity. Xiaomi Mi Band 4 became a real bestseller thanks to its colored AMOLED-The screen and affordable price, but the initial setup of the device often raises questions from new owners.Proper pairing of the gadget with the smartphone is the foundation for the correct operation of all functions, including sleep monitoring, step counting and receiving notifications from social networks.
The process of integrating a tracker into your digital ecosystem requires careful attention, especially when choosing software and Bluetooth versions. Unlike a regular watch, it is not just the visibility of the device that matters, but the stable exchange of data through specialized protocols. Initial synchronization determines how accurately your workouts will be recorded and how quickly alerts will arrive. If you miss important stages of setting up, you risk permanent communication breaks or incorrect sensor readings.
In this guide, we will take a detailed look at every step, from unpacking to fine-tuning notifications so you can immediately start enjoying all the features of the device. We will look at the features of working with Android and iOS operating systems, since the connection algorithms may differ slightly. Ready for the process will take no more than 10-15 minutes of your time, but will ensure comfortable use of the gadget for many months.
Preparing the device and smartphone for the first launch
Before you start looking for a device, you need to make sure that the tracker itself is ready to go. Xiaomi Mi Band 4 comes with a factory charge, but often it is minimal to save battery life during long-term storage in stock. If you see a battery icon on the screen or the device does not respond to touch, it should be installed in the charger. Use the original cable or compatible power supply with a current of no more than 1A so as not to damage the power controller.
Checking your smartphone’s compatibility is an important step, and it requires certain operating systems to work smoothly: Android 4.4 or iOS 10.0 and up. It’s also critical that the phone has Bluetooth enabled and GPS permissions allowed. Without geolocation activation, the Android operating system can block device scanning as a security threat.
☑️ Checking before connection
Don’t ignore the need to update the system software of the smartphone itself. Older versions of phone firmware may contain bugs in the Bluetooth stack that prevent stable connection to new accessories. Make sure your phone isn’t in power-saving mode, as it can limit the background activity of services needed to find the gadget.
Installation and configuration of the Mi Fit application
The control center for your fitness tracker will be the official Mi Fit app (known in some regions as Zepp Life), download the program exclusively from official stores: Google Play Store for Android or App Store for iOS. Using third-party apk files or modified versions can lead to leakage of personal health data or unstable synchronization.
Once installed, start the app and create a Mi Account. This is a must, because all your activity, weight and sleep data are stored in the cloud and linked to that profile. When registering, specify the correct data: height, weight, date of birth and gender. These parameters are used by algorithms to calculate calories burned and analyze sleep phases, so a mistake of a few pounds can significantly distort the statistics.
💡
Use the same Mi Account on all devices if you plan to use multiple Xiaomi gadgets or smart scales so that all the statistics are collected in one place.
When you first log in, the app will ask for a number of permissions. To work properly, you must agree to access notifications, contacts (to display callers' names), location and background work. If you block background activity, the app will not be able to retrieve data from the wristband until you manually open it, making continuous monitoring impossible.
⚠️ Note: When registering with the Mi Fit app, it is better to choose the server region automatically or the one that is closer to your actual location. Choosing the wrong region (e.g. China if you are in Europe) can lead to delays in data synchronization or problems with map display in the activity section.
The process of pairing the bracelet with a smartphone
The connection process in the Mi Fit app is as automated as possible. After authorization, go to the Profile tab and select Add Device. In the list of available gadgets, find Mi Band 4. The application will go into search mode, scanning the space around. At this point, a vibration or Bluetooth icon may appear on the tracker screen, confirming readiness for (conjugation).
When the application detects your bracelet, an image of the device with its unique identifier will appear on the smartphone screen (MAC-Press "Confirm" or "Confirm" and the bracelet will be asked to confirm the connection, usually in the form of an icon. OK Touch the touch button on the tracker to confirm the action.
If the automatic search does not give results for more than 2-3 minutes, try restarting Bluetooth on your smartphone or restarting the application itself. Sometimes resetting the bracelet to factory settings through the device menu, if it has been used before helps. The initial communication installation process can take up to 30 seconds, during which the encryption keys are exchanged.
Once the connection is successful, it will automatically synchronize time and date, which is critical because the time on the wristband is taken from the network via the phone, and if the time on the wristband is lost after the phone is restarted, then the sync has not been completed or the application has been blocked by the system.
Configure notifications and displayed information
One of the main functions of the tracker is to receive notifications. In order for them to come, you need to go to the device settings in the Mi Fit application and select the "Application Notifications" section. Here you will see a list of all the programs installed on the phone. Activate the switches opposite the ones whose messages you want to see on your wrist: Telegram, WhatsApp, Viber, calls, SMS and others.
Remember, the bracelet only broadcasts the contents of the notification. If the message came when the bracelet was not connected to the phone, it will not appear on the screen later when the connection is restored. It is also important to adjust the display language. In the section "Bracelet settings" -> "Language and time", you can choose which format the text will be displayed. For Cyrillic (Russian), support is full, but the font may look smaller due to the peculiarities of the encoding of the characters.
| Type of notification | Screenplay | Possibility of answer | Duration of the display |
|---|---|---|---|
| Incoming call | Name/Number, reset button | No (only reset) | Before reply or discharge |
| SMS message | Text of the message (up to 3 lines) | No. | 5-7 seconds |
| Notification of the annex | Icon + headline | No. | 5-7 seconds |
| Alarm clock | Vibration + watch icon | Disconnection/Delay | Before the blackout |
For comfortable reading long messages, you can adjust the font size in the application itself, although this is not affected by the small screen of the Mi Band 4. It is more useful to set the Do Not Disturb Mode (DND). At a given time (for example, at night), the bracelet will only vibrate when the alarm clock is triggered, ignoring calls and messages, which will allow you to not interrupt the deep sleep phases.

Calibration of sensors and adjustment of sports modes
For accuracy of pulse measurements and steps, a primary calibration is recommended. Although the Xiaomi Mi Band 4 uses an optical PPG sensor, its readings can vary depending on the density of the skin fit. Wear the bracelet 1-2 cm above the wrist bone, without tightening the strap too tightly, but also preventing it from dangling. This will ensure better contact of the sensor with the skin.
There are a lot of sports modes available in the app: running, walking, biking, swimming, etc. When you first start Running Outside, the bracelet will try to catch a GPS signal through a connected smartphone. This is necessary to build a route track. Indoors, an accelerator that counts the steps according to the nature of the hand movement. To improve the accuracy of the pedometer, you can manually enter the length of your step.
The model is marked 5 ATM, which means it can be immersed to a depth of 50 meters. However, this is only true for fresh water. After swimming in the pool or sea, the device must be rinsed with fresh water and wiped dry, since chlorine and salt can damage the sealing pads and charging contacts.
⚠️ Warning: Do not use the bracelet in hot water, sauna or jacuzzi. High temperature and steam can penetrate the inside of the case, damage the adhesive layer of the screen and lead to condensation under the display, which is not a guarantee case.
Solving Common Connection Problems
Even if you follow all the instructions, you can have technical difficulties. One of the most common problems is that the bracelet is visible in the Bluetooth menu of the phone, but it doesn't connect in the Mi Fit app. This is due to a pairing conflict, in which case you need to go to the Bluetooth settings of the phone, find the Mi Band 4 there, click "Forget the device" or "Untie" and then repeat the search inside the Mi Fit application.
Another common situation is a constant disconnection of communication. If the bracelet regularly loses connection, check the power saving settings. On Android, you need to add the Mi Fit app to the exceptions ("White List"), prevent the system from "killing" its process and allow auto-start. Without this, the operating system will force the application to close to save charge, breaking the connection with the tracker.
💡
If the bracelet is not visible in the app but is visible in the phone's Bluetooth, be sure to remove it from the list of paired devices in the Bluetooth settings, otherwise the app will not be able to establish its connection.
In rare cases, a complete reset of the bracelet is required, which can be done through the device's menu (Settings -> Reset) or through the app if there is still a connection. Once reset, the device will return to factory settings, and the connection procedure will have to be reset, as with a new gadget, which often helps to correct software errors accumulated during use.
