Modern wearables have become an integral part of an active person’s life, and the Xiaomi Mi Band 4 remains one of the most popular fitness trackers on the market due to its price-to-feature ratio.The process of initial activation of the device can seem confusing for a beginner, especially given the need to use specialized software to fully unlock the potential of the gadget.
In this article, we will take a closer look at every step, from unpacking and charging to fine-tuning notifications and sports modes. Properly calibrating sensors and installing the latest firmware version will ensure the accuracy of heart rate and steps, which is critical for those who are watching their health.
Before you start pairing, make sure your smartphone meets the minimum system requirements. Android version 4.4 or iOS 9.0 and higher are required to work properly, as well as the Bluetooth module enabled. Ignoring these basic requirements often leads to connection problems that users mistakenly mistake for a device defect.
Tracker preparation and installation of Mi Fit application
The first step is to physically activate the device, remove the capsule from the strap and connect it to the charger included in the kit, and the indicator on the screen should light up, confirming the charge, which is a prerequisite for the Bluetooth module of the tracker to turn on.
The main application for Mi Band 4 is Mi Fit (rebranding in Zepp Life in some regions), which can be downloaded from Google Play or the App Store. Do not use third-party utilities from unverified sources, as they may incorrectly transmit health data or contain malicious code.
⚠️ Warning: Do not attempt to charge the tracker if the contacts on the capsule or charger are wet.This can lead to oxidation of the contacts and irreversible damage to the electronics.
After installing the app, launch it and create a Xiaomi account or log in through a social media profile. Account registration is necessary to synchronize data in the cloud and save your activity history when changing your smartphone.
It is important to give the app all the permissions it requests, including geolocation and notifications. Without location permission, the Android operating system can block the search for Bluetooth devices, considering it a security breach.
The process of pairing and activation of the device
To start searching for a device, open the Profile tab in the lower right corner of the Mi Fit interface and select Add Device. From the list of available gadgets, select Mi Band 4. The app will warn you that the tracker may not be visible to other devices during the search.
Hold the bracelet closer to your smartphone. The tracker screen will display a vibration signal and a Bluetooth icon, which means ready to (mating). Click on the vibrating icon on the bracelet screen to confirm the action.
- 📱 Make sure that the Bluetooth settings of the smartphone is not pre-coupled with the bracelet, otherwise the application may not see it.
- 🔋 The battery charge of the tracker should be at least 10-15% Successfully complete the activation procedure.
- 📶 Keep your smartphone and bracelet at a distance of no more. 1-2 Meters apart during firmware updates.
Once the connection is successful, the app will suggest upgrading the firmware to the latest version, a critical step because the factory version of the software often contains errors in the pulsemeter or step-counting algorithms, which can take anywhere from 5 to 10 minutes to be upgraded and cannot be interrupted.
⚠️ Warning: During a firmware update, the smartphone screen should be turned on and the Mi Fit app open in the foreground.Switching to other tabs may break the connection.
If pairing doesn’t happen on the first try, try rebooting your smartphone and resetting the bracelet through the settings menu on the tracker itself. In rare cases, clearing the Bluetooth cache in the phone’s operating system settings helps.
Setup of notifications and data display
One of the main functions of the smart bracelet is to display notifications. To set them up, go to the device profile in the application and select "Application Notifications." Here you can activate the display of messages from messengers, social networks and system events.
To properly work notifications on iOS, you also need to enable the display of widgets in the iPhone notification center. Android sometimes requires you to give the Mi Fit app permission to “Access Notifications” in the phone’s system settings, unless this happens automatically.
| Type of notification | Description of action | Feature of the work |
|---|---|---|
| Incoming challenges | Vibration and contact name | The possibility of rejecting a call (Android) |
| SMS/Messages | Text of the message (first characters) | Depends on the preview settings in the OS |
| Applications (WhatsApp, Telegram) | Name of sender and text | It requires active internet on your phone. |
| Alarm clock | Vibration at a given time | It works autonomously from the phone. |
It’s important to understand that the Mi Band 4 doesn’t have a built-in microphone or speaker, so you can’t answer a call or listen to a voice message directly from your wrist.
You can also set up Do Not Disturb mode in this section, which automatically turns off notification vibrations at a given time, such as at night, which helps save battery power and does not wake you up in the middle of the night with unnecessary vibrations.
Personalization of dials and interface
Visuals are an important part of using the gadget. Xiaomi Mi Band 4 supports color. AMOLED-screen, which allows you to set bright and detailed dials. To change the design, go to the "Dials" section in the device profile.
The app offers a vast library of free and paid dials. You can choose from classic analog style, large-digit digital format or animated images. Some dials allow you to output additional data, such as the weather or current pulse.
To load a new dial, you need a stable Internet connection, after downloading the image is stored in the tracker memory, and the Internet is no longer required to display it. However, the device memory is limited, so you can not store more than 2-3 user dials at the same time.
⚠️ Attention: Complex animated dials consume more energy. If you are critical to autonomy, choose static black backgrounds, as AMOLED-The screen does not consume energy to display black pixels.
You can also adjust the brightness of the backlight and the time it burns in the screen settings. The automatic brightness control mode works based on the data of the smartphone light sensor, so for its correct operation, the application must have access to the appropriate sensors of the phone.
Fitness tracking and health monitoring
The main purpose of the device is to track physical activity. The Mi Band 4 automatically recognizes five main activities: running, walking, cycling, swimming and training in the hall.
The device is equipped with an optical heart rate sensor that takes measurements in the background or on request. For maximum accuracy, it is important to attach the bracelet tightly to the skin, placing it 2-3 cm above the wrist bone.
- 🏊♂️ Water resistance 5 ATM allows swimming in the pool, but it is not recommended to dive from great depths.
- ❤️ For accurate measurement of the pulse during training, it is better to turn on the constant monitoring mode in the application.
- 🚶♂️ The stepmer is calibrated automatically, but for the correct calorie calculation it is important to indicate your weight and height in the profile.
The app also includes PAI (Personal Activity Intelligence), a unique index that measures your activity not just by the number of steps you take, but by the impact on your cardiovascular system, and the user's goal is to keep your PAI index above 100 units per week.
Swimming users can use stroke tracking and SWOLF (swimming efficiency) mode, and then sync the data to their smartphone, where they can analyze heart rate and calories in detail.
☑️ Checking before training
Additional features and hidden capabilities
In addition to the standard features, the tracker has a number of useful tools, including controlling music on a smartphone, searching for a phone (vibration and sound on the phone when you press the bracelet), and unlock the screen for Windows laptops (requires the installation of additional software on the PC).
One of the most useful features is sleep monitoring, and the device automatically detects the phases of sleep: light, deep and light. REM-It's a phase, and it's also a daytime nap, and it's a basis for recommendations to improve rest.
The secret of the reboot
Weather Forecast is also available, which broadcasts data from your phone, and allows Mi Fit to access geolocation and background data to work, without which the weather widget can show outdated information.
For statisticians, data export is useful, and the app allows you to upload workout and sleep reports that can be integrated with Google Fit or Apple Health, creating a single health ecosystem.
Solving typical problems when setting up
Despite the simplicity, users may encounter difficulties, and a common problem is that the bracelet can't see the smartphone, in which case you need to make sure that the device is not connected to the phone through the standard Bluetooth menu, but only through the Mi Fit app.
Another common scenario is fast battery drain: If a fully charged tracker runs out in 1-2 days, check if there is not a constant monitoring of the pulse at a high frequency or if there are too many notifications from active applications.
💡
If the bracelet stops vibrating when notified, check whether Do Not Disturb or Night Mode is on the device or in the app.
Synchronization problems are often solved by forcing the Mi Fit app to stop in Android settings and clearing its cache, after which you will need to re-enter the username and password from your Xiaomi account.
In the event of a complete loss of connection with the device, when the bracelet does not respond to charging and touching, a deep discharge may be required. Leave the bracelet on charging for several hours, even if the screen does not light up immediately.
💡
Most Mi Band 4 software errors are solved by updating the firmware or reconnecting the device in the application, rarely requiring service intervention.
