Integrating wearables into everyday life has become the standard for millions of users, and the Xiaomi Mi Band 4 remains one of the most popular fitness trackers on the market due to its availability and functionality.Properly configured, the device opens up access to heart rate monitoring, sleep analysis, step counting and receiving notifications from social networks right on the wrist. The initial activation process requires attention to detail, as skipping one stage can lead to pairing errors or unstable application operation.
Before you start pairing, you need to make sure your Android smartphone is fully ready to interact with external Bluetooth devices, which means not only having a battery charge, but also having the communication modules work correctly, as well as installing the latest version of the system software. Owners of new phone models may face stricter security policies that require additional permissions to operate the tracker’s background services.
In this article, we will take a closer look at every step of the connection, from downloading official software to fine-tuning notifications so you can use all the features of your gadget without restrictions. You will learn about common errors that often occur when you first start, and how to quickly fix them. Proper setting from the beginning will ensure stable data synchronization and prolong the life of the battery tracker.
Preparation of the smartphone and charging the tracker
The first and most important step is to ensure that the battery level of the tracker itself is sufficient, as the device may not turn on or enter the low voltage pairing mode. To charge the Mi Band 4, you need to remove the capsule from the strap and install it in a special charging dock, which connects to the battery. USB-The display on the screen should light up, confirming the beginning of the process, and full charging usually takes about an hour.
Simultaneously with charging the gadget, you should prepare the smartphone: check if Bluetooth is on, and make sure the phone is in visibility mode for other devices. If you have previously used other fitness bracelets or smartwatches, it is strongly recommended to remove them from the list of conjugated devices in Bluetooth settings to avoid addressing conflicts. Clean slate is a principle that often helps to avoid problems with connecting a new device.
⚠️ Note: Do not attempt to charge the tracker by connecting the contacts directly to the wires without using an original or certified docking station, this can short-circuit and the capsule fails.
It’s also worth checking the operating system version of your Android smartphone, as the Mi Fit (or Zepp Life) app requires Android 5.0 or higher to work properly. On older versions of the OS, the app may simply not install from the store or work incorrectly, constantly crashing out when trying to synchronize data. Updating the phone’s system often solves hidden problems with Bluetooth drivers.
Installation and configuration of the Mi Fit application
To manage the tracker, you need to use an official application that acts as an intermediary between the hardware part of the bracelet and the phone’s operating system. Previously, the main application was Mi Fit, but recently Xiaomi has been actively transferring users to the Zepp Life platform, which has a more modern interface and advanced functionality. You can download the application for free from the official Google Play Market store by typing the corresponding query in the search bar.
Once installed, you need to register for a Mi Account or log in through an existing profile linked to the Xiaomi ecosystem, which is a must because all health and activity data is stored in the cloud and synchronized between devices. It is important to register with the correct data: date of birth, gender and approximate height, since these parameters are used by algorithms to calculate calories and analyze sleep quality.
During the initial setup process, you will be asked to provide a number of permissions that you need to take care of. For the background synchronization and notifications to work properly, you must allow access to geolocation, contacts, microphone (for voice search, if supported) and memory. Without geolocation permission in Android 6.0 and above, scanning of Bluetooth devices can be blocked by the system.
💡
If the Zepp Life app doesn’t see the bracelet when searching, try temporarily switching to the classic Mi Fit app for primary binding, and then updating the firmware.
The process of pairing devices
After successfully registering and setting up a profile in the application, the tracker is directly connected. On the main interface screen, select the Profile tab or click on the add-on icon of a new device, usually located at the top corner of the screen. From the list of available categories, select Bracelet or Mi Band, after which the system will start searching for active devices within Bluetooth range.
When your Mi Band 4 ID appears on your smartphone screen (usually an alphanumeric code), click on it to start the mating procedure. The tracker screen should display a graphic image of the phone and a vibration signal confirming the connection request. To complete the process, you need to touch the touch button on the bracelet, confirming your actions.
☑️ Checklist of successful pairing
It is important to understand that the pairing process should occur through the application interface, and not through the standard Bluetooth menu of Android settings. If you try to connect the device directly through system settings, the application will not be able to access the data, and the functionality of the bracelet will be limited only to displaying time and steps without synchronization.
💡
The pairing is always initiated from within the companion app, not through the smartphone’s Bluetooth system menu.
Update of firmware and basic configuration
Once the app is successfully connected, it will prompt the tracker software to be updated to the current version, a critical step, as the factory firmware may contain errors that affect sensor accuracy or Bluetooth connectivity stability. The upgrade process takes several minutes, during which time the phone and bracelet must be in close proximity to each other.
During the screen update, the tracker may go out and light up, and the phone will display a progress bar. Interrupting this process, such as turning off the smartphone screen or leaving the application, can lead to a software failure that requires complex recovery.
| Parameter | Description | Recommendation |
|---|---|---|
| BLE version | Protocol of communication | Bluetooth 5.0 |
| Battery capacity | Autonomy of work | 135mAh |
| Protection | Degree of water protection | 5 ATM (up to 50 m) |
| Sensors. | Type of pulse sensor | PPG (optical) |
After the update, you should adjust the basic parameters, such as the time format (12 or 24 hours), the measurement system (metric or imperial) and the interface language. For Russian-speaking users, it is important to make sure that the bracelet settings are Russian, otherwise the notifications will come in the form of unreadable characters or in English.
Set up notifications and permissions for Android
One of the main features of the smart bracelet is the ability to receive notifications about calls, SMS and messages from instant messengers. To work correctly, you need to go to the application settings and find the Notifications or Application Notifications section. You should activate sliders in front of the desired programs such as WhatsApp, Telegram, Viber or standard calls.
However, simply ticking the app isn’t enough: Android, especially in versions 10, 11, 12 and later, aggressively manages background processes to save energy. You need to manually go to your phone’s settings, find the Zepp Life app (or Mi Fit) in the installed program list, and allow it to “Start” and work in the background. Without this, the system will “kill” the application process, and notifications will stop coming on your wrist.
⚠️ Note: On smartphones Xiaomi, Huawei and Samsung there are additional aggressive settings of energy saving, which can block the tracker even with common permissions.
For MIUI owners, there is a very important step: you need to lock the application in memory. To do this, open the list of running applications, find Mi Fit/Zepp Life and press the lock so that the system does not unload it when cleaning the memory. It is also recommended to turn off battery savings specifically for this application in the power settings.
Why do notifications come with a delay?
Solving Common Connection Problems
Despite the simplicity of the procedure, users may encounter a situation where the phone does not see the bracelet or communication is constantly lost.The first thing you can do is try to reboot both devices: turn off and turn on the smartphone, and reboot the tracker through the settings menu on the bracelet itself. Often this clears the Bluetooth stack cache and eliminates temporary software glitches.
If the device is “hangy” and does not respond to touch, you can perform a forced reboot by charging it for a few seconds or holding the touch button (if the model allows). In extreme cases, when software methods do not help, you may need to completely reset the bracelet to factory settings through the device menu, after which the pairing procedure will need to go again.
Connection issues can also be caused by an outdated version of the app or operating system, make sure there are no updates available for Zepp Life in the Google Play Market, and check for updates for Google Play services that are responsible for Bluetooth Low Energy.
