The appearance on the market of Xiaomi Mi Band 4 was a landmark event in the wearable electronics industry, because it was the first tracker of the brand, which received a full color color. AMOLED-For many users, the initial activation and setup process becomes a quest, especially given the synchronization features with Android and iOS operating systems. Proper device configuration at launch is critical for accuracy in heart rate tracking and sleep quality.
In this article, we will look at all the steps of connecting a gadget, from choosing the right application to fine-tuning notifications that often come with a delay or do not appear at all. You will learn how to avoid typical pairing errors and why the Bluetooth phone system menu can interfere with the bracelet. A key feature of the fourth version is the support of dynamic dials and the ability to install third-party fonts, which makes the interface personalization almost limitless.
Before you start the software part, make sure your smartphone meets the minimum requirements: Android 4.4 or iOS 9.0 and higher. Connection stability depends on the version of the Bluetooth module in the phone, so on older models there may be periodic communication breaks. Let's move on to software preparation.
Preparation of the smartphone and choice of application
The foundation for any smart bracelet is a specialized aggregator application. For the Mi Band 4, the main tool is either Mi Fit (now renamed Zepp Life) or the newer Xiaomi Wear (Mi Fitness), which depends on your preferences: the first application has the widest functionality and data history, the second one is a more modern interface, but may have less compatibility with older trackers.
Download the application should be exclusively from official sources: Google Play Market for Android or App Store for iOS. APK-Files from questionable resources can lead to leakage of personal health data or unstable synchronization. Once installed, run the program and create an account using a phone number or mail.
When registering, pay attention to the region you choose in your profile. For servers and weather widgets to work correctly, it is recommended to indicate the real location or region "Russia / CIS" if you live in this geographic zone. Incorrect choice of region can block access to some functions of the community or dial store.
⚠️ Warning: Do not give the app excessive permissions to access contacts and microphone unless you plan to use voice input or phone book sync.
Once you create an account, the system will ask you to enter anthropometric data: height, weight, date of birth and step length, which are used by algorithms to calculate calorie expenditure and distance. Carelessly treating these numbers will lead to significant errors in the statistics of training, since the tracker does not have any training. GPS-The module calculates the distance based on the length of your step.
The process of pairing and activation of the device
Now, the most important step is physically connecting the tracker capsule to the phone. Unlike regular headphones, the Xiaomi Mi Band 4 can't just be found in the Bluetooth list and click "Plug in." Direct pairing through the Android or iOS system settings often leads to errors when the device is in "Connected" status, but the data is not transmitted.
The right algorithm requires a strict sequence. First, turn on Bluetooth on your smartphone, then open the Mi Fit app, go to the profile and select "Add Device." Only then the app will start searching for nearby devices. When the bracelet image appears on the phone screen, click on it to begin the mating procedure.
☑️ Checklist of successful connection
During the process, a vibration signal and a graphical confirmation key will appear on the tracker screen, a security measure to prevent your device from connecting to other people's phones within range. Press the touch button to confirm the action. If the bracelet has been previously in use, the application may suggest resetting it to factory settings before re-binding.
If the search does not yield results for more than 30 seconds, try rebooting Bluetooth on the phone or rebooting the tracker itself through the settings menu on the screen of the gadget. Sometimes it helps to temporarily disable geolocation, although modern versions of Android require it to be enabled to work Bluetooth Low Energy (BLE).
⚠️ Note: If you have previously connected the bracelet via the standard Bluetooth menu, be sure to click "Forget the device" or "Unpair" in your phone settings before trying to connect again via the app.
Language and regional settings
One of the first problems that users face is the lack of Russian or the incorrect display of Cyrillic in notifications. By default, Mi Band 4 can be configured in English or Chinese. To change the interface language, you need to go to the application settings, select the Profile section, find your bracelet and open the Device Settings.
In the settings menu, look for "Language" where you can force Russian to be installed. However, if you see "square" symbols or question marks instead of text after switching, it means that the bracelet is not loaded with the corresponding font package. In the Mi Fit application, this is solved automatically when you change the language, but sometimes manual synchronization is required.
To properly display notifications from instant messengers (Telegram, WhatsApp, Viber), you need to go to the "Application Notifications" section in the bracelet profile, you need to activate sliders in front of the desired programs. It is important to understand that the bracelet only broadcasts the text of the notification, it does not allow you to respond to messages or view pictures.
Why aren't the notifications coming?
The format of the time and date deserves special attention. They usually pull up automatically from the phone when synchronized. If the time on the bracelet is behind or shows an incorrect time zone, check the date settings in the smartphone itself and make sure that you have automatic synchronization over the network. Manual setting of time on the bracelet is impossible, it is completely dependent on the host.
Customization of dials and interface
The Mi Band 4 color screen offers a huge opportunity for personalization. Unlike its black and white predecessors, you can use vivid images, animations and complex widgets. To change the dial, go to the app, select your tracker and click on "Dial settings."
There is an online dial store available, which offers thousands of options, from minimalist watches to complex interfaces with a pedometer and a pulseometer on a single screen. downloading takes place via Bluetooth, so the process can take anywhere from 30 seconds to 2 minutes depending on the complexity of the graphics and the speed of the connection.
In addition to the standard options, there are advanced methods of installing custom dials through third-party utilities (for example, Notify for Mi Band), which allows you to download any images from the phone gallery.
| Type of dial | Features | Impact on the battery | Complexity of installation |
|---|---|---|---|
| Standard. | Basic clock, steps | Low. | Minimum |
| Online (from the store) | Bright colors, animations | Average. | Automatic. |
| Dynamic | Responds to steps/pulse | High. | Medium |
| Castomium (photo) | Any image | Depends on the picture. | Requires third-party software |
Do not abuse complex animation and bright colors if you are critical autonomy of work. AMOLED-The technology implies that black pixels do not consume energy, so dark dials significantly save battery power compared to light ones.
Configuration of health monitoring and training
The main function of the device is to track activity, and you can adjust the pulse rate in the app, from once every 30 minutes to continuous monitoring, and it's clear that the "every minute" mode will give the most accurate picture, but significantly reduce the battery life.
For sports, the bracelet menu has a "Training" mode. Before the active phase, you must choose the type of activity: running, walking, cycling, swimming, etc. The Mi Band 4 has a waterproof 5 ATM, which allows swimming in the pool, but for open water it is less accurate due to the lack of built-in GPS.
💡
To increase the accuracy of step count, calibrate the step length. Go a known distance (e.g., 100 meters), count the steps, and divide the distance by the number of steps. Put the number in the profile settings.
The sleep monitoring function is automatic, and the bracelet analyzes the phases of deep and superficial sleep, as well as the phases of sleep. REM-To work properly, you need to wear the bracelet tightly, but not pressing the wrist so that the optical pulse sensor on the back can read readings even at night.
Also available is the Idle Alert feature, which is that if you sit still for an hour, the bracelet vibrates to get up and stretch, which is a useful feature for office workers, leading a sedentary lifestyle.
Troubleshooting and resetting settings
During operation, there may be situations when the bracelet stops syncing, freezes or does not respond to touch. The first step should always be to reboot the device. On the Mi Band 4, this is done through the Settings menu -> System -> Unbind, or simply reboot if it is available on the menu.
If the software reset doesn't work, you can do a full reset, so you can go to the bracelet menu and find Reset and confirm the action, and all the data on the device will be deleted and it will return to factory status, and then you will need to re-assign it through the application as a new device.
A common problem is to de-synchronize the time after the battery is discharged. If the bracelet is completely discharged and turned off, after charging, it can reset time, in which case it is enough to open the Mi Fit application and wait for the synchronization to be completed, the time will automatically update.
⚠️ Note: If you experience frequent failures (spontaneous reboots, data loss), try clearing the Mi Fit app cache in your Android settings or reinstall the application, saving important data in your account cloud beforehand.
To extend the life of a lithium polymer battery, don’t leave the device on charge after reaching 100% for a long time and try not to discharge it to zero regularly.The optimal storage range is 40-60% charge, unless you plan to use the bracelet for a long time.
💡
The Mi Band 4’s stable performance depends 90% on the right power saving settings on Android. Be sure to add the Mi Fit app to the battery exclusion list.
