How to connect a smart bracelet Xiaomi Mi Band 4

Smart fitness bracelet Xiaomi Mi Band 4 became a real hit in the world of wearable electronics, offering users color AMOLED-It has a screen and advanced activity tracking at an affordable price, but in order for the device to work properly and transmit pulse or step data, it needs to be properly synchronized with the smartphone. The initial setup process can seem confusing for beginners, especially given the need to use specialized software.

In this article, we will discuss in detail all the steps of connecting the tracker to mobile devices based on Android and iOS, and also consider the nuances of working with the Mi Fit application (now Zepp Life). You will learn how to avoid common pairing errors, how to update the firmware for stable operation and why sometimes the bracelet does not see the phone. The correct initial setting is the key to long battery life and measurement accuracy.

Before you start, make sure that your smartphone meets the minimum system requirements: Android 4.4 or iOS 9.0 and above, and also the Bluetooth module is turned on. It is important to note that direct connection through the standard settings of the phone system will not give full functionality - using a proprietary application is strictly necessary to activate all the functions of the gadget.

Preparation for the first launch and charging

The first step before trying to pair is to check the battery level. Gadgets are often stored in warehouses for a long time, so the battery can be completely discharged. it is necessary to remove the tracker from the silicone strap and insert it with contacts down into the connector of the charger connected to the USB-port.

After connecting to the power supply, the battery icon should appear on the screen. If the screen does not light up immediately, wait 5-10 minutes. To activate sleep mode after a deep discharge, sometimes you need a short-term shutdown and reconnect the charging cable. Full charging before first use is recommended for calibrating the power controller.

Also at this stage, it is worth checking the integrity of the sensor on the back of the capsule. Dirt or protective film can interfere with the measurement of the pulse. Wipe the surface with a soft cloth. Make sure that geolocation services (GPS) are turned on on on on your smartphone, since in modern versions of Android and iOS this is a mandatory requirement for Bluetooth Low Energy (BLE) scanning.

Do not try to plug the device in if it shows signs of malfunction, such as heavy heating when charging. In normal mode, the capsule should only warm slightly. If the charging indicator flashes red or does not light up at all, check the contacts for oxidation or contamination.

Installation and configuration of the Mi Fit application

The main tool for managing the bracelet is the application, which is now called Zepp Life (formerly known as Mi Fit), which can be downloaded from official stores: Google Play for Android or the App Store for iPhone. APK-Files are not recommended because they may contain malicious code or work incorrectly with synchronization servers.

Once installed, start the app and create a Mi Account or log in through an existing profile, which is necessary to save your activity history in the cloud. During the registration process, it is important to specify the correct data: date of birth, height and weight, since based on these parameters, algorithms calculate calories burned and distance traveled.

When you first log in, the system will request various permissions. To fully work, the Xiaomi Mi Band 4 must provide access to:

• 📍 Geolocation – for tracking routes and Bluetooth operation.
• 🔔 Notifications – to display calls and messages on the bracelet screen.
• 🏃 Fitness data – to record activity in the background.
• 📸 Camera – if you plan to use the remote shutter function.

💡

On Xiaomi, Redmi and Poco smartphones, be sure to turn on auto-run for the Mi Fit app in the battery settings, otherwise the system will close it in the background and notifications will stop coming.

It is important not to ignore requests to access the background of the application. Android aggressively optimizes power consumption, which often leads to a break in the connection with the tracker. In the battery settings, select the "No Limits" mode for the companion application.

The process of pairing the bracelet with a smartphone

The process of adding the device is intuitive, but it requires care. Open the application, go to the Profile tab and select Add Device. In the list of available gadgets, find Mi Band 4. The application will automatically start scanning the surrounding space for Bluetooth signal.

When you see a picture of a bracelet on your smartphone screen, click on it to start pairing. The tracker screen should display a vibration and a pattern lock or confirmation code at that point. Press the touch button on the bracelet (the tick icon) to confirm (the pairing). If the codes on the phone and the bracelet match, the connection will be established.

⚠️ Warning: Don't try to plug the bracelet into the standard Bluetooth menu of your phone's settings! this will cause a pairing error.The whole procedure must be done strictly inside the Mi Fit app.

In rare cases, if the device is not, try rebooting Bluetooth on your smartphone or rebooting the tracker itself. To reboot the Mi Band 4 capsule, you need to put it on charge or find the appropriate option in the device menu (if it was already connected).

Once the connection is successful, the app will suggest a firmware update, a critical step, as the factory version of the software often contains bugs that affect pedometer accuracy and screen performance. Wait until the download and updates are finished without turning off the smartphone screen.

Configuring notifications and interface

One of the main functions of the tracker is to display notifications. In the app, go to the device settings and find the "Application Notifications" section. Here you can choose which programs will duplicate their messages on the wrist: messengers, social networks, email clients or calls.

To run this feature on Android, you need to give the Mi Fit (Zepp Life) app access to read notifications, and the system will take you to the appropriate security settings menu, where you need to activate sliders opposite the desired application. On iPhone, notification settings are duplicated from the Bluetooth system settings and the application itself.

You can also set up in this section:

• ⌚ Dials – upload new screen themes.
• 🔔 Alarms and timers – set vibrational reminders.
• 📳 Motion reminders – vibration when sitting for a long time.
• ☀️ Weather forecast – synchronization of temperature data.

Note that the display of text messages with Cyrillic (Russian) on the Mi Band 4 is fully supported. However, if you see squares instead of text, check if the bracelet settings have the correct font language. Sometimes you need to switch the interface language of the application itself to English, and then return to Russian to update the fonts.

Compatibility table and characteristics

Understanding the technical limitations helps avoid frustrations. The Xiaomi Mi Band 4 has a specific set of characteristics that determine its compatibility with various operating systems. Below is a table showing the main interaction parameters.

As you can see from the table, iPhone users may face some limitations in the functionality of notifications compared to Android owners, which is due to Apple’s security policy, which restricts third-party applications from accessing the messaging system.

💡

It is critical for iPhone owners to keep the Zepp Life app open in the background for timely data synchronization, as iOS does not allow a permanent background connection.

It’s also worth considering that some features, such as music control or phone search, require the appropriate modules in your smartphone. Older phone models may not support all Bluetooth Low Energy commands implemented in the wristband.

Solution: Bracelet not connected

If the pairing process is interrupted or the phone can't see the device, don't panic. Most often the problem is in the Bluetooth cache or the application version conflict. First, try removing the device from the Bluetooth list in your phone settings (forget the device), then restart the smartphone.

The second step is to clear the Mi Fit app data, go to your phone's settings, find the app, select Storage and click Clear Data (not just cache), which will reset the app's settings, but won't delete your account, and then log in again and try adding the device.

If that doesn't work, reset the bracelet completely. In the tracker menu, find the System (or Settings) section and select Unbind or Reset. Once reset, the bracelet will go into standby mode and you can add it as a new device.

⚠️ Warning: Resetting the bracelet will delete all accumulated activity data that has not yet been synced to the cloud.

In some cases, the problem may be due to antivirus software on the phone that blocks Bluetooth scanners. Try temporarily disabling protection or adding an app to exceptions. Also check if the bracelet is connected to another phone in range - it can automatically connect to it.
