Synchronizing a fitness tracker with a smartphone is the first and most important step to start using the device. It is through Bluetooth pairing that you will be able to receive notifications about calls, track physical activity and adjust the dials. The process of connecting the Xiaomi Mi Band 4 to a mobile device is technically simple, but requires a certain sequence of actions to successfully establish communication.
Owners of gadgets often face nuances that depend on the phone's operating system. Whether it's Android or iOS, the basic principle remains the same, but the management software may differ. It's important to understand that without a special application, the wristband's functionality is limited only to displaying time and steps, so installing the software correctly is critical.
In this article, we will discuss in detail the algorithm of actions that will avoid common errors in the first run, you will learn how to choose the right application, how to activate the search mode and what to do if the device is not detected by the system.
Preparation for device synchronization
Before starting the procedure, you need to make sure that both devices are ready to work.The battery charge of the tracker should be sufficient for the operation, although a minimum level is enough to enable the pairing mode. If the bracelet is new, it may be in transport mode, so it should be removed from the capsule and put on charging for at least 10-15 minutes.
The smartphone also requires pre-preparedness. Make sure the Bluetooth module is activated in the system settings. For stable connection, it is recommended to enable geolocation (GPS), since modern versions of operating systems require this permission to scan nearby devices. Without GPS enabled, the phone may simply "not see" your fitness bracelet.
⚠️ Warning: Don't try to connect the bracelet directly through the standard Bluetooth menu in your phone's settings like a regular headset. Mi Band 4 requires the mandatory use of a proprietary app to authorize and share encryption keys.
It’s also worth checking your smartphone’s operating system version. Mi Fit (or Zepp Life) requires Android 5.0 or higher or iOS 10.0 or higher to work properly. On too old versions, the app may not start or run unstable, interrupting the connection at the most inopportune moment.
💡
Before you start installing the application, close all background programs to free up RAM and speed up the process of finding the device.
Select and install Mi Fit or Zepp Life
The main tool for managing the tracker is the mobile app. For a long time, the standard was the Mi Fit app, which was recently renamed Zepp Life. They are functionally identical to work with the Mi Band 4, so you can use any of them. You can download the program from official stores: Google Play for Android or the App Store for iPhone.
When installing, pay attention to the permissions requested. The app needs access to Bluetooth, geolocation, contacts and notifications. If you deny access to notifications during the installation phase, you will later have to manually reconfigure the rights in the system, which can be inconvenient. For Android users, it is also recommended to turn off energy savings for this application so that the system does not “kill” the sync process in the background.
Once you download and install, start the app. You'll be asked to create a Mi Account or log in to an existing one. This is a must, because without an account, data synchronization is impossible. You'll want to automatically choose the region when registering, or the one that matches your SIM card, so that the servers run as fast as possible.
- 📱 Go to the app store of your smartphone.
- 🔍 Type “Zepp Life” or “Mi Fit” into the search».
- ⬇️ Click the “Install” button and wait for the download to complete.
- ✅ Open the application and log in via Mi Account.
Step-by-step instructions for connecting to Android
The process of pairing with Android devices is the most common. After installing the application and logging in, go to the home page and click on the profile icon in the lower right corner. Then select the option "Add device" and in the list of available gadgets, find the Mi Band 4.
The app will ask you to confirm the action. At this point, it is important not to look for the bracelet in the Bluetooth settings of the phone itself. Just click "Search" in the app. When the tracker vibrates and the Bluetooth icon appears on the screen, tap the bracelet screen to confirm the pairing (the tick icon). If the screen is out, tap the touch button several times to activate.
☑️ Checklist of connection
After successful confirmation, a message will appear on the smartphone screen about the successful (binding). The system will suggest updating the tracker firmware to the current version. Updating firmware is highly desirable, since new versions correct translation errors, improve connection stability and add new faces. The process can take several minutes, while holding the phone next to the bracelet.
⚠️ Note: During the firmware update, the phone screen must be turned on and the Zepp Life app must be running in an active window.
Features of connecting to the iPhone (iOS)
Owners of Apple smartphones need to take into account the features of the iOS operating system. the procedure for finding and adding a device in the Mi Fit (or Zepp Life) application is similar to the Android version. However, for stable notifications and the background of the application, additional settings are required in the iPhone system.
After pairing, be sure to go to the settings of the iPhone itself, the Bluetooth section. Find your Mi Band 4 in the list, click on the "i" icon next to the name and make sure that the "Connect Devices to This iPhone" switch is activated. Also in the Privacy → Fitness & Motion app settings, access for Mi Fit should be allowed.
Why does the iPhone lose touch with the bracelet?
To receive notifications from messengers (WhatsApp, Telegram, Viber), you need to go to the settings of the Mi Fit application, select the profile of the bracelet and go to the section "Application Notifications", where you need to activate switches opposite the desired programs. On the iPhone will also need to confirm permission to access notifications in the system pop-up--WIDGET:keypoint:The main difference of iOS is the need for manual confirmation of access to notifications for each application separately in the system settings of the phone.-->
Configuring notifications and work parameters
Once successfully connected, it’s time to fine-tune the wristband, which can broadcast notifications of calls, SMS and social media messages on the wrist. To make this work, the device profile in the Notifications section must activate the appropriate items. Android may also require permission to “Access Notifications” in system settings.
An important parameter is the wrist lift to turn on the screen. In the bracelet settings menu, you can select the sensitivity of this function or the time interval in which it is active (for example, only during the day), also adjust the time format (12 or 24 hours) and the vibration of the buttons. All changes are applied instantly after pressing the save button.
To save charge, you can turn off unnecessary functions such as constant monitoring of the pulse or notification of achievements. However, to fully use the tracker as a fitness assistant, it is recommended to keep monitoring sleep and steps active.
| Parameter | Description | Impact on the battery |
|---|---|---|
| Pulse monitoring | Frequency of measurements (1, 5, 10, 30 min) | High. |
| Wrist lifting | Activation of the screen when moving | Average. |
| Notifications | Vibration of messages | Low. |
| NFC (for the NFC version) | Payment and access | Low. |
Solving Connection Problems
Sometimes the sync process can go awry. If the phone can't see the bracelet, try rebooting the smartphone. This is a classic but effective method of cleaning the Bluetooth stack cache. Also make sure the bracelet isn't connected to another phone. The Mi Band 4 can only pair with one device at a time.
If the problem persists, reset the bracelet. To do this, in the menu of the tracker itself, find Unbind or Reset. After that, in the app on your phone, remove the device from the list and try to add it again as new. Often, removing the application and re-installing it with data cleaning helps.
- 🔄 Reboot your smartphone and bracelet.
- ❌ Remove the device from the Bluetooth list in your phone settings.
- 🗑️ Remove the bracelet from the Mi app Fit/Zepp Life.
- 🔌 Reset the settings on the bracelet itself.
⚠️ Warning: When the bracelet is reset, all accumulated data that is not synchronized with the server will be lost. Make sure that the application has time to download the steps and sleep data before resetting.
💡
If nothing works, try connecting the bracelet to another person's phone, and if it works there, it's a problem with your smartphone settings, if it doesn't, it could be a hardware defect in the tracker.
