In this material, we will analyze all the nuances of connecting to Android and iOS, and also eliminate typical errors.

It's the mobile app that acts as the control center where you store your entire performance history.

Preparation for pairing of the device

Before starting the procedure, you need to make sure that your smartphone meets the minimum system requirements. For stable operation of the Xiaomi Mi Band 4, you need a Bluetooth module version 4.0 or higher. Also make sure that the tracker itself is charged with at least 20-30% battery so that it does not turn off during the installation of updates.

The critical step is to install the right software, depending on your phone model and region, different versions of the apps can be used. Global versions of the bracelets typically require Mi Fitness (formerly Zepp Life), while Chinese versions may require Zepp.

Remember to enable geolocation (GPS) in your smartphone settings. Many users ignore this item, but in modern versions of Android and iOS, location permission is necessary to scan Bluetooth devices with third-party applications. Without it, the phone simply will not see the bracelet.

Instructions for Android users

Android smartphone owners need to do a series of preparatory steps in the system. First, open your Bluetooth settings and find your tracker on the list of available devices. If it shows up there, click on the gear icon or select Forget the device / Unpair the pairing. This is to avoid connection conflict.

Next, go to the settings of the application you will use for control. In the permissions section, be sure to activate Bluetooth access, geolocation and background launch. Some shells (MIUI, EMUI) also require you to remove the power saving restrictions for a particular application, otherwise the system will “kill” the synchronization process.

Now, launch the app and press the add-on button. The system will start searching. When your Mi Band 4 image appears on the screen, tap it to start pairing. The bracelet will display a vibration signal and ask you to confirm the action — click on the tracker touch button.

⚠️ Warning: If the app says "Device not found" while searching, don't rush to restart the phone. Try just turning off and turning Bluetooth on in the notification curtain, then repeat the search.

Setup for iPhone owners (iOS)

The process of connecting to Apple devices has its own peculiarities due to the more stringent operating system security rules. First of all, make sure you have the latest version of iOS installed. Open System Settings → Bluetooth and make sure the switch is active.

Unlike Android, on iOS, you don’t need to manually remove old pairings through the system menu unless the bracelet was previously tied to this Apple ID. Just run the Mi Fitness or Zepp app. When you first start, the system will ask for permission to use Bluetooth and notifications – be sure to agree with all the points.

When the app detects the tracker, the system interface request window will appear on the iPhone screen. Press Hide. Then the Mi Band 4 screen will light up the ID (or vibration pattern) that needs to be confirmed by touch, the process takes no more than 30 seconds with a stable signal.

💡

Keep the bracelet and phone close together (no further than 10-15 cm) during primary pairing for the fastest and most stable connection.

Solving the problems with the detection of the bracelet

The fact that the smartphone does not see the fitness tracker is one of the most common, often because the bracelet is already paired with another phone or “hang” in standby mode, in which case a complete reset of the device itself through the More → Factory Reset menu (or a similar item depending on the firmware version).

It’s also worth checking the background process list. If you have Android, go to Bluetooth settings, look for smart devices (sometimes disguised as MI Band 4 or just a set of characters) and delete them. After that, reboot your smartphone, this will clear the Bluetooth stack cache.

In rare cases, the problem lies in the firmware version of the bracelet itself, and if the device was left idle for a very long time, its software could become so outdated that new applications can't see it, in which case it may be necessary to use third-party utilities to force the upgrade, but this is already an advanced level.

Update of firmware and calibration

Once the Mi Band 4 is successfully connected, the first step is to update the firmware, which is an important step, as new versions of Firmware fix the heart rate sensor errors and improve the stability of the Bluetooth connection.

The upgrade process requires that the bracelet be near the phone and the smartphone screen be turned on.The interruption of the boot can cause the tracker to stop responding.During the upgrade, the Mi Band 4 can reboot several times - this is normal behavior.

After the update, you should calibrate the pedometer. Walk a known distance (for example, 100 meters) and check the data with the application. If the error is large, in the profile settings, specify your exact height and step length, this will help the algorithms to calculate the path traveled more accurately.

Configure notifications and functions

The main value of the tracker is the ability to receive notifications without taking your phone out of your pocket. In the application, go to Profile → Notifications. Here you can choose which applications will duplicate messages on your wrist: social networks, instant messengers, calls or SMS.

Note that text messages may not be displayed if the phone’s privacy settings hide the content of notifications on a locked screen. Also, for notifications to work, the companion application must have permission to work in the background, otherwise the Bluetooth connection will be broken by the system to save energy.

You can also configure women's health cycles, step goals and motion reminders, and all of that data is synchronized with the cloud to allow you to plot long-term activity schedules, and you can have exercise modes that automatically recognize the type of load.

⚠️ Warning: Don't set notifications too frequently, this greatly speeds up the Mi Band battery discharge 4, reducing the time of autonomous operation with 15-20 days 5-7 days.
