Modern wearable gadgets such as Xiaomi Mi Band 4, have become an integral part of the smart home ecosystem and personal health tracker. However, for owners of Android smartphones, the initial integration process may not seem obvious due to the many nuances of working with Bluetooth and specific software. Successful sync unlocks heart rate monitoring, sleep tracking and notifications, turning a simple bracelet into a powerful activity monitoring tool. In this material, we will analyze in detail the algorithm of actions that guarantees a stable connection.
Before starting the procedure, it is important to make sure that your smartphone meets the minimum requirements for the operating system version and the presence of the module Bluetooth. Often, users skip the preparation step, which leads to errors in finding a device or an inability to complete pairing. We will consider not only the standard connection scenario through the official application, but also methods for solving common problems that users encounter when setting up a bracelet.
Preparatory stage before pairing
Any interaction with peripheral devices begins with checking the basic settings of the smartphone. Make sure that your gadget has Bluetooth activated and geolocation is turned on. This last requirement often surprises users, but Android data protocols require location access to correctly scan BLE devices. Without turning on GPS, the application may simply not “see” the bracelet in the list of available devices.
Next you need to charge the tracker itself. If Mi Band 4 has been completely discharged, it may not respond to touches and may not emit a search signal. Connect the capsule to the charger for at least 15-20 minutes. It is also recommended to reset Bluetooth settings on your phone if you have previously tried to connect other devices and encountered address conflicts. This will clear the connection cache and provide a clean start.
⚠️ Attention: Do not try to pair the bracelet directly through the Bluetooth system menu in the phone settings. This will result in a binding error and the application will not be able to gain full access to the device's functions.
An important aspect is to check the compatibility of software versions. Although Mi Band 4 is a fairly old device, it requires the latest versions of Google Play system services for push notifications to work correctly. Make sure your phone has access to the Internet and is synchronized with your Google account.
Before starting setup, restart your smartphone - this will clear the RAM and eliminate background conflicts with Bluetooth services.
Installing and setting up the Mi Fit application
The central element of the Xiaomi ecosystem is the application Mi Fit (in some regions renamed to Zepp Life). It is through this software package that all tracker parameters are controlled. The application should be downloaded exclusively from the official store Google Play Market or Galaxy Storeto avoid malicious modifications that can intercept your biometric data.
After installation, run the app and log in to your account. You can use an existing profile Xiaomi, log in through your account Google, Facebook or WeChat. If you don't have an account yet, the registration process will only take a couple of minutes: you will need to enter your phone number or email and come up with a strong password. Without authorization, the functionality of the application will be severely limited.
- 📱 Download the Mi Fit application from the official source.
- 🔐 Sign in or register a new account.
- 📍 Grant the application all requested permissions, including access to geolocation and notifications.
- 🔋 Make sure Bluetooth and the Internet are turned on on your phone.
In the “Profile” section, click the button "Add device". The application will prompt you to select the type of gadget from the list. Find the model Mi Band 4in the list of trackers. It is important not to confuse it with newer versions, since their firmware and communication protocols are different. After selecting the model, an automatic search for the device within range will begin.
The process of synchronization and binding
When the application detects the bracelet, a vibration and a specific icon will appear on the capsule screen, prompting you to confirm the action. You need to tap the touch button on Mi Band 4to accept the pairing request. This stage is critical: if you do not confirm the action within 10-15 seconds, the process will be reset and the search will have to start again.
After confirmation, the process of establishing connections and possibly updating the tracker firmware will begin. At this time, the bracelet screen may go dark or the progress bar may appear. It is strictly forbidden to interrupt this process, as this can lead to the device becoming “bricked” or malfunctioning microcontroller. Wait for the message that the installation was successfully completed.
| Setting stage | User action | Indication on the bracelet |
|---|---|---|
| Search for device | Click “Add” in the application | Absent |
| Pairing request | Tap on the bracelet screen | Vibration and Bluetooth icon |
| Update Software | Do not touch the device | Download process / Update icon |
| Completion | Checking data in the application | Main dial |
Upon completion of the procedure, the application will offer to configure basic parameters: goal by steps, units of measurement, time format and interface language. It is recommended to immediately set the Russian language if it is not detected automatically in order to avoid confusion in the menu in the future. Also at this stage, the initial synchronization of the time, which is taken from your smartphone, occurs.
☑️ Successful synchronization
Setting up notifications and monitoring functions
One of the main reasons for buying a fitness bracelet is the ability to receive notifications directly on your wrist. In the application menu, go to the settings section of the connected device and find the “Application notifications” item. Here you can activate the display of messages from WhatsApp, Telegram, Viber and system events, such as calls and SMS.
For this function to work correctly, you must grant the Mi Fit application special rights in the settings of Android itself. Go to Settings → Applications → Mi Fit → Notifications and allow the display of all types of alerts. In addition, in the battery settings, you should disable power saving for this application so that the system does not “kill” the process in the background, which is a common problem on Xiaomi, Samsung and Huawei smartphones.
⚠️ Attention: On smartphones with aggressive memory management (for example, MIUI) you need to pin the Mi Fit application in the list of recent tasks and enable autorun, otherwise notifications will stop coming a few hours after you unlock the screen.
In addition to notifications, health monitoring parameters are configured in this section. You can activate continuous heart rate measurement, sleep phase monitoring and sedentary lifestyle reminders. Please note that constant heart rate measurement significantly increases the bracelet's battery consumption, reducing battery life from 20 days to 10-12.
How do notifications work on a locked screen?
If the phone screen is locked, the bracelet will only receive a notification if the application has permission to run in the background and access the lock screen. Some versions of Android require additional permission to access “special features.”
Solving common connection problems
Despite the simplicity of the procedure, users often encounter a situation where the phone does not see the bracelet or the connection is constantly interrupted. First of all, check whether Mi Band 4 is connected to another phone. The bracelet can only maintain an active connection with one device at a time. If it was previously paired with another gadget, you need to unlink it through the app on that device or perform a factory reset.
If the device appears in the phone's Bluetooth list as "Paired" but does not connect in the app, remove it from the system list of paired devices. Go to Bluetooth settings, find Mi Band 4, click on the gear icon and select “Unpair” or “Forget device”. After that, repeat the search procedure inside the Mi Fit application.
- 🔄 Restart the smartphone and bracelet (in the bracelet settings, select “Reset” or hold the button).
- 📶 Clear the Mi Fit application cache in the phone settings.
- 📍 Check if geolocation is enabled (GPS) during search.
- 🔋 Make sure that the bracelet charge is above 20%.
In rare cases, the problem lies in the incompatibility of Bluetooth versions. Although Mi Band 4 uses the standard Bluetooth 5.0 BLE, Very old smartphones with Bluetooth 4.0 may experience stability issues. It is also worth checking whether you have modified versions of firmware or custom ROM installed, which can block the operation of Google system services necessary for the tracker to work.
90% of connection problems can be solved by completely removing the device from the Bluetooth system list and re-pairing exclusively through the Mi Fit application.
Additional features and customization
After successful setup, you get access to advanced features that are not available out of the box. For example, you can change watch faces by downloading thousands of options from the online catalog within the app. This allows you to personalize the appearance of the device to suit your style or current mood. Some watch faces display weather, moon phases, or additional activity statistics.
For advanced users, there is the option of installing third-party software, such as Gadgetbridge or using tools to unlock hidden features (for example, displaying the weather without a phone or changing screen brightness). However, such manipulations require caution and may lead to loss of warranty or unstable operation of the device. The official firmware Mi Band 4 already contains a sufficient set of functions for most use scenarios.
⚠️ Attention: Installing unofficial dials or firmware through third-party utilities is at your own peril and risk. An error when writing data can permanently disable the touch controller.
Remember to regularly sync your data when opening the application. Although the bracelet stores activity information for up to 30 days, regular uploading to the cloud allows you to build long-term progress graphs and participate in challenges with friends. This turns the device from a simple pedometer into a full-fledged personal trainer.
To save battery, disable wrist lift to turn on the screen if you often gesture with your hands, or set the schedule for this function only during the daytime.
Why does the bracelet not vibrate when receiving notifications?
Most often the problem is in the Android power saving settings. The system “kills” the Mi Fit process in the background. You need to add the application to the white list (exceptions) in the battery settings and allow auto-start. Also check whether a specific messenger is included in the list of notifications inside the Mi Fit application itself.
Is it possible to connect Mi Band 4 to two phones at the same time?
No, the hardware of the bracelet supports an active connection with only one smartphone. However, you can quickly switch between devices by unlinking the bracelet in the app on one phone and linking it on another. The data is saved in the Xiaomi cloud account.
What to do if the application does not see the bracelet when searching?
Make sure that geolocation (GPS) is turned on. Clear the list of paired devices in your phone's Bluetooth settings. Reboot both devices. If this does not help, reset the bracelet to factory settings through the device menu.
How to change the interface language on the bracelet?
The language changes automatically depending on the system language of your smartphone. If the language on your phone is Russian, after synchronization the bracelet should switch to Russian. If this does not happen, try changing the language in the settings of the Mi Fit application itself in the profile section.
How long does the Mi Band 4 hold a charge?
With standard use (heart rate monitoring every 30 minutes, notifications, raising your wrist), the bracelet lasts up to 20 days. With active use of GPS (via phone) and constant heart rate monitoring, the operating time is reduced to 10-12 days.
