Modern wearables are no longer just toys and have become full-fledged health-control assistants. Xiaomi Mi Band 4 remains one of the most popular fitness trackers due to its excellent price-to-feature ratio. However, the process of initial activation for many users causes difficulties associated with the features of the software.
To work properly, the device must pair with the smartphone through the official application. Without this step, the tracker will remain only hours with basic functionality, without saving the training history and without receiving notifications. In this article, we will discuss in detail how to properly configure the device and avoid typical synchronization errors.
The connection process requires care, especially when choosing software, as the MIOT ecosystem (Xiaomi IoT) periodically changes supported platforms.You will need a tracker itself, a charged smartphone with an Android or iOS operating system, and a stable Internet connection to download software. We will look at all the nuances so that you can start using the gadget immediately after unpacking.
Preparation of the tracker and smartphone to pair
Before you search for a device in the Bluetooth list, make sure the bracelet is ready to go. remove the Mi Band 4 from the package and remove the protective film from the contacts on the back of the capsule. QR-Mi code or logo, which means the device is on and in standby mode.
It is important to check the battery power, as when the power level is low, the wireless module can work unstable. Connect the tracker to the charger for 15-20 minutes if the indicator does not light up immediately, this ensures that during the setup and firmware update, the device does not turn off suddenly.
⚠️ Warning: Do not try to connect the tracker through the standard Bluetooth menu in the phone settings. Direct pairing without the app will lead to an error or incorrect notifications.
On the smartphone should be enabled in advance geolocation (GPS). This is a requirement of the Android operating system for search. BLE-Bluetooth Low Energy, not active GPS-The app module simply won’t see your bracelet in the list of available connections.
Also make sure that the phone has the latest version of the operating system installed. Android recommends version 5.0 and higher, iOS 10.0 and higher.Odd software may contain bugs in the Bluetooth stack that prevent stable connection to wearable electronics.
Selecting and installing the right application
The key is choosing software. Mi Fit has long been the main application, but in 2021 Xiaomi began active implementation of the new Zepp Life platform. Both options are suitable for the Mi Band 4, but Zepp Life receives more recent interface and features updates.
Download the application should only be from official stores: Google Play Store for Android or App Store for iPhone. APK-Files or modified versions of programs may lead to leakage of personal data or inability to authorize a Mi Account.
Once installed, start the app and create an account, you can use a phone number, email or social media accounts (Google, Facebook, Apple), registration is required to store statistics in the cloud and synchronize data between devices.
When you first log in, the system can request permission to access notifications, contacts, and geo-location, and you have to agree to all the points, otherwise the smart notification and route tracking functionality will not work.
Connection process via Zepp Life and Mi Fit
The algorithm for the actions in the applications is almost identical. After authorization, go to the Profile tab (usually the human icon in the lower right corner). Click on the Add Device or + button, which is usually located at the top of the screen.
From the list of available gadgets, select Mi Band 4. The app will ask you to confirm the action and start searching. At this point, a vibration and a Bluetooth symbol may appear on the tracker screen. To confirm the pairing, tap the touch button on the bracelet (the tick or vibration icon).
☑️ Checklist of successful connection
If you use Mi Fit, the interface may be slightly different visually, but the logic remains the same: search, model selection, confirmation on the device, and after a successful connection, automatic time-date synchronization will begin.
It is important not to close the application or switch to other programs during the initial setup. The encryption key exchange process can take from 30 seconds to 2 minutes.
Firmware update and basic setup
Immediately after the connection, the system will suggest updating the tracker software, a critical step, as factory firmware often contains bugs fixed in newer versions. Update can take anywhere from 5 to 15 minutes depending on Internet speed and Bluetooth version.
| Parameter | Description | Recommendation |
|---|---|---|
| FW version | Built-in version | Always update to the last one. |
| Battery charge | Required energy levels | Minimum 20% before launch |
| Distance | Distance between phone and bracelet | Not more than 1 meter |
| Phone screen | State of the smartphone display | Keep it on. |
During the upgrade, the Mi Band 4 can reboot and the screen can go out and light up again. Don't panic, it's normal behavior. The main thing is to keep the phone close and not close the application. If the process is interrupted, the tracker can go into recovery mode, and you have to repeat the procedure again.
What to do if the update is suspended?
Once the software is successfully installed, you can start customizing it. The profile menu -> bracelet settings are available:
- 🎨
- ⌚
- 📳
- 🔔
Pay special attention to setting up notifications, where you can choose which apps (WhatsApp, Telegram, Viber) to receive signals from, and it is also recommended to turn on the display of the caller's name if the phone book is synchronized with the application.
Extended functions and personalization
Xiaomi Mi Band 4 has a wide range of functionality that is revealed only after deep tuning, first of all, the pulsemeter. Although it works automatically, periodic check of readings through the Status menu will help make sure that the sensor fits tightly to the wrist.
Athletes are interested in training settings. You can set goals for steps, calories and sleep time. PAI (Personal Activity Intelligence) is a unique metric that calculates the load on the heart. The desire to keep PAI above 100 is considered optimal for health.
⚠️ Attention: To accurately calculate steps and calories, you need to include your real height, weight and age in your application profile.
Phone Search is available. If you activate it in the wristband menu, the phone will ring loudly, even if it's in silent mode. This is convenient when the gadget is lost in the bag or under the pillow. And the reverse function is to search for the wristband through the app.
You can download additional themes under Dials, some of them are paid, but most of them are free, and it takes a few seconds to install a new theme, and it changes the look of the device, so you can adapt it to your style of clothes or your mood.
Solving Typical Connection Problems
Despite the simplicity of the procedure, users often encounter errors, and the most common problem is "Device not found," which is solved 90% of the time by restarting Bluetooth on the phone or restarting the app itself.
If the bracelet is visible on the list but the connection is reset, try "forgetting" the device in the Bluetooth system settings, and then searching again through the app. Sometimes cleaning the Zepp Life app cache in the phone settings helps.
💡
If the bracelet was previously connected to another phone, be sure to perform the unbind in the app on the old device. Mi Band 4 can block the connection to the new phone while busy with the old connection.
Notification problems are often associated with aggressive energy savings on Xiaomi, Huawei or Samsung smartphones. You need to add the tracker app to the list of exceptions ("Sun Run", "No Limits") in the phone's battery settings. Otherwise, the system will "kill" the synchronization process in the background.
In rare cases, a complete reset of the tracker to factory settings through the menu on the bracelet itself (Settings -> System -> Factory Reset) helps, which deletes all data and returns the device to the "out of the box" state, which often resolves software conflicts.
💡
The Mi Band 4’s performance is 90% dependent on the right energy saving settings on your smartphone, and without background permissions, smart functions (notifications, pulse) won’t work.
