Modern wearables have become an integral part of the daily lives of millions of users, and the Xiaomi Mi Band 4 is at the forefront of this segment due to its value for money ratio. However, immediately after unpacking, many face the first difficulties associated with the initial synchronization of the gadget with the smartphone, which is not always smooth, as it requires a certain sequence of actions and setting access rights in the operating system.
In this guide, we will take a look at how to install the software correctly, activate the Bluetooth connection, and avoid the typical errors that often lead to tracker failures. It is important to understand that successful pairing depends not only on the serviceability of the bracelet itself, but also on the correct settings of your mobile device. Below is a step-by-step guide that will help you get the device into operation in minutes.
Preparation for pairing: what to do before inclusion
Before you try to connect the gadget to the phone, you need to perform a number of preparatory manipulations. The most common mistake of beginners is trying to connect the bracelet directly through the Bluetooth menu in the settings of the smartphone. This is absolutely impossible, because the application will not be able to correctly control the device, and it will appear as connected, but not working.
Make sure your Mi Band 4 has a charge first. Often new devices come with a battery dead, plug it into the charger (contact charging comes with it) and wait until the battery image appears on the screen, and then you can move on to the software part.
💡
Always charge the Mi Band 4 to 100% before first use – this will help calibrate the power controller and avoid problems with the indication of the level of charge in the future.
The official app was previously used, but Xiaomi is now actively transferring users to the Zepp platform (formerly known as Amazfit).For older models, such as the fourth version of the bracelet, support in the Zepp app is maintained, but sometimes functionality can be limited compared to the Mi Fit.
- 📱 Make sure that your smartphone is Bluetooth enabled and GPS (geolocation, as without GPS Android device search is often impossible.
- 📲 Download the Zepp or Mi Fit app from Google Play or the App Store (for iOS).
- 🔋 Charge the bracelet before the logo or greeting animation appears.
- 📶 Make sure you have a stable internet connection to register an account.
Installation and configuration of the Mi Fit / Zepp application
Once you download the installation file, you need to install the app on your smartphone. The account registration process is a mandatory step, without which you can not log in. You can register using your phone number, email address or social networking accounts such as Facebook or Google.
When you first run it will request access to various functions of the phone, and it's critical to allow access to geolocation and notifications, and if you deny access to Android location, it will simply prevent the scanning of Bluetooth devices from going ahead, a system restriction imposed for security reasons.
☑️ Checking before connection
In the app interface, go to Profile or Mine (usually the person icon in the lower right corner) and there is the Add Device button. Click on it and select from the Mi Band 4 list. The app will ask you to confirm the device search, and then the scan will begin.
⚠️ Warning: If the app is looking for a device for a long time but does not find it, try restarting your smartphone and turning off/on Bluetooth. Sometimes cleaning the Bluetooth cache in the developer's settings helps.
The process of connecting Xiaomi Mi Band 4 to a smartphone
When you select the bracelet model in the app, you'll see a pairing request on your smartphone screen, and at the same time, you'll see a vibration on the Mi Band 4 itself, and you'll see a graphic symbol that looks like a ring or a tick, asking you to confirm the action, which is protection against unauthorized connection.
Press the touch area of the bracelet (the round button below the screen) to confirm the pairing. The smartphone screen will display a message about the successful connection. Now the gadget will suggest updating the firmware if a new version is available. It is strongly recommended to update immediately, as older versions of the software may contain errors that affect the accuracy of sensors and stability of the connection.
During the upgrade, the screen will burn and the percentages will change. Interrupting this process can cause the device to stop responding. Make sure the bracelet is near the phone and the battery is sufficiently charged.
What if the bracelet does not vibrate when asked?
After successful updates and initial data synchronization, the app will offer to configure notifications from applications (WhatsApp, Telegram, calls), where you can flexibly manage which alerts will arrive on your wrist.
Setup of notifications and bracelet functions
One of the main features of Mi Band 4 is to receive notifications, so that they come correctly, you need not only to allow them in the application, but also to give the Android or iOS system the right to show them. From the app menu, go to your device settings and select "Application Notifications".
Here you will see a list of all the programs installed on the phone, you need to activate sliders in front of those messengers and social networks, the messages from which you want to see on the bracelet, and you should also pay attention to the settings of the time format (12 or 24 hours) and language, although the Mi Band 4 supports Russian by default.
| Function | Where to set up | Recommendation |
|---|---|---|
| Lift up | Profile -> Mi Band 4 -> Wrist Lift | Turn on for convenience, but it consumes the battery |
| Sleep monitoring | Profile -> Mi Band 4 -> Sleep monitoring | Include "Sleep Assistant" for detailed statistics |
| Notifications | Profile -> Mi Band 4 -> Notifications | Leave only the important ones so that they don’t vibrate constantly. |
| Target by step | Profile -> Mi Band 4 -> Purpose of activity | Set a realistic goal (e.g., 8,000 steps) |
You can adjust the frequency of measurements manually, every 10, 30 minutes, or constantly, and constant monitoring significantly reduces battery life, so you can choose between 10 and 30 minutes.
Solving Connection and Synchronization Problems
Despite the simplicity of the procedure, users often encounter errors. One of the most common problems is that the bracelet is visible in the phone's Bluetooth list, but the application says "Device not found." In this case, you need to go to the Bluetooth settings of the smartphone, find the Mi Band 4 there and click "Forget the device" or "Cancel pairing."
Then you have to shut down the Mi Fit/Zepp app completely and start the search again. Also, the problem can be in the Bluetooth version. Mi Band 4 works with Bluetooth 5.0, but is backwards compatible with 4.0. If you have a very old phone, there may be problems with connection stability.
Another reason for the failures is the aggressive energy saving on Xiaomi, Huawei and Samsung smartphones.The system can “kill” the background process of the application, which causes the bracelet to stop synchronizing data and skipping notifications.
- 🔋 Add the app to battery exceptions ("No restrictions»).
- 🔒 Block the app from the list of recent tasks (lock).
- 📡 Allow the auto-run of the application in the system settings.
- 🔄 Reinstall the app if nothing helps.
⚠️ Warning: Don't try to connect the Mi Band 4 to two phones at once through the same app. To change the phone, you must first break the pair in the app on the old device, otherwise the new phone will not be able to establish a connection.
Changing the interface language and resetting settings
Sometimes, the bracelet interface is in English or Chinese, despite the Russian language installed in the app and on the phone, this is solved by changing the region in the application. Try changing the region from Russia to China or Singapore in the application profile settings, and then reconnect the bracelet.
If the device is not behaving properly, freezes or does not respond to touch, you may need a complete reset. In the bracelet menu (swipe left), find the item "More" (More) -> "System" -> "Unbind" or "Reset" (Reset).
💡
Changing the region in the app to China often solves problems with the lack of Russian language or dials, but can change the data storage server.
After resetting, you will have to reconnect as with a new device, and make sure you remember your username and password from your Mi Account, as without them, you will not be able to log in to the application.
