Smart fitness bracelet Xiaomi Mi Band 3 has been one of the most popular wearable devices on the market for several years due to its excellent price-functionality ratio. However, like any gadget, it requires proper initial setup to fully work with your smartphone. Many users encounter difficulties already at the first turn-on stage, not understanding why the tracker is not displayed in the Bluetooth search.
In this material we will look at all the intricacies of pairing the device with the operating system Android. You will learn which application needs to be installed, how to avoid common mistakes when registering an account, and what to do if the gadget is not visible to the phone. Correct setup will allow you to receive notifications, track sleep and physical activity without failures.
Before moving on to the software part, it is worth paying attention to the physical preparation of the device. Charge the bracelet fully using the special cable included in the package, as it is often only partially charged at the factory for storage in the warehouse. Make sure that there is no protective film on the metal contact pad on the back of the case, which is often forgotten to be removed, which prevents charging and normal operation.
Preparing for synchronization and installing the application
The first and most important step is to install the correct software on your smartphone. To work with the third generation of fitness trackers from Xiaomi the application is used Mi Fit (in some regions it is renamed to Zepp Life). You need to download it exclusively from the official store Google Playto avoid malicious modifications.
After installing the application, you will need to create an account or log in to an existing account Xiaomi. This is a mandatory requirement, since all health and activity data is stored in the manufacturer’s cloud. When registering, carefully fill out the data, especially your date of birth and weight, since the algorithms for calculating calories burned depend on them.
⚠️ Attention: When you first launch the application, it will ask for many permissions to access geolocation, contacts and notifications. For the bracelet to work correctly, you must allow access to all requested functions, otherwise notifications from instant messengers will not be received.
It is also important to check the version of your phone's operating system. For stable operation Mi Fit requires Android version 4.4 and higher. If you have an older version, the application may not work correctly or may not install at all. In this case, you should consider updating the firmware of the smartphone itself.
Turn on geolocation (GPS) on the phone before searching for the device - without this, modern Android will not allow the application to scan the Bluetooth environment.
The process of pairing the bracelet with the phone
After successful authorization in the application, you can begin directly connecting the devices. On the main screen of the application Mi Fit go to the "Profile" tab and select "Add device". In the list of available gadgets, you need to find and select Mi Band 3.
Now take the tracker in your hands. A pairing request may appear on the bracelet's screen, or it may begin to vibrate, waiting for confirmation. The search process will begin in the application on the smartphone screen, which may take from a few seconds to a minute. As soon as the device is found, a Bluetooth symbol and a confirmation button will appear on the bracelet screen.
Click on the vibrating area on the tracker body to confirm the pairing. If everything went well, you will hear a characteristic sound signal and the time will appear on the screen. From this moment Mi Band 3 is considered connected to your account.
☑️ Checking the connection
Sometimes the process may be interrupted while checking for updates. Don't panic, this is a normal situation. Wait for the download and installation of the new firmware version to finish, if it is offered, since older versions of the software often contain errors that interfere with a stable connection.
Setting up notifications and health functions
After successful connection, a wide range of settings opens to you. In the "Profile" -> "Mi Band 3" section you can configure the information displayed. First of all, you should enable notifications from the necessary applications, such as WhatsApp, Telegram, calls and SMS.
In order for notifications to work correctly, you must also configure access to notifications in the Android system settings. Go to your phone's settings, find the "Notifications" section and make sure that the app Mi Fit is switched to the "On" position. Without this step, the phone will block data transfer to the bracelet.
| Function | Description | Where to set |
|---|---|---|
| Wrist lift | Turn on the screen when you turn your hand | Bracelet settings |
| Goal by steps | Daily activity rate | Profile -> Mi Band 3 |
| Heart rate monitor | Pulse measurement intervals | Profile -> Mi Band 3 |
| Alarm clock | Vibrate signal at a specified time | Profile -> Mi Band 3 |
The sleep and heart rate monitoring function deserves special attention. Automatic measurement heart rate allows you to build more accurate load graphs, but consumes more energy. You can adjust the measurement interval in the application, finding a balance between data accuracy and device autonomy.
Solving problems with connection and visibility
One of the most common problems is the situation when the phone does not see the bracelet, although it is turned on. This is often due to the fact that the device has already been previously paired with the phone through the standard Bluetooth menu. In this case, you need to go to the Bluetooth settings of your smartphone, find Mi Band 3 in the list and select “Forget device” or “Cancel pairing.”
Another reason lies in the application cache Mi Fit. If the app was unstable, accumulated temporary files may interfere with correct scanning. Try clearing the application cache through the Android settings or completely reinstalling it by first removing the bracelet from the list of devices in your profile.
⚠️ Attention: Do not try to connect the bracelet directly through the Android system Bluetooth settings menu. Pairing must occur strictly within the Mi Fit application, otherwise the functionality will be limited or absent.
If all else fails, perform a complete reset of the bracelet. On the tracker body, find the “Reset” item and confirm the action. After rebooting, the device will be ready for new (pairing) like new.
What to do if the bracelet keeps disconnecting?
If the bracelet loses connection after short periods of time, check the power saving settings. Many smartphone manufacturers (Huawei, Xiaomi, Samsung) aggressively kill background processes. Add Mi Fit to the exceptions or "white list" of the energy saving system, prohibiting memory clearing for this application.
Firmware update and calibration
Immediately after connection, the application may offer to update the tracker software. This is a critical stage, as new firmware versions often fix bugs Bluetooth stack and improve the accuracy of the sensors. The update process takes from 5 to 10 minutes and requires that the bracelet be near the phone.
During the update, the bracelet screen will fade and light up, and the progress will be displayed as a percentage. It is absolutely impossible to interrupt this process. Place the phone and bracelet on the table and do not touch them until the application reports successful completion.
After the update, it is recommended to calibrate the pedometer. Walk a known distance (for example, 100 meters) and compare the data on the bracelet with reality. In the application, you can enter a correction factor for step length, which will increase the accuracy of calculating the distance traveled and calories.
Regular firmware updates are the best way to extend the life of the battery and ensure a stable connection with your smartphone.
Frequently asked questions (FAQ)
Is it possible to connect Mi Band 3 to two phones at the same time?
Officially, the bracelet supports pairing with only one smartphone at a time. However, if you are signed into the same Mi Account on two phones, the data will be synced in the cloud, but (real-time) notifications will only arrive on the device with an active Bluetooth connection. To switch, you need to break the connection in the application on the first phone.
Why does the bracelet not vibrate when there is an incoming call?
Check three things: whether the Vibrate function is turned on in the settings of the bracelet itself, whether the Do Not Disturb (DND) mode is activated on the phone or in the Mi Fit profile, and whether the application has permission to access contacts and call logs. Often the problem is solved by simply restarting the application.
Is Mi Band 3 compatible with iPhone?
Yes, the device is fully compatible with iOS. To connect, you need to download the Mi Fit (Zepp Life) application from the App Store. The setup process is similar to the Android version, however, some features, such as quick reply to messages, may be limited by the Apple operating system.
How to change the watch face on Mi Band 3?
In the Mi Fit app, go to the device profile and select "Watch face settings". There is a watch face store available where you can download new free or paid themes. After downloading, click “Install”, and the new design will be downloaded to the tracker.
