The first familiarity with the popular activity tracker begins from the moment it is activated, and for many Xiaomi Mi Band 4 users, this process is the first test of ingenuity.The device comes from the factory in a state of deep energy saving, so simply pressing the touch button will not power the screen. This is done specifically to keep the lithium polymer battery charged during long-term storage in warehouses and retail chains.
Many owners mistakenly believe that the gadget is faulty if it does not respond to touch immediately after being removed from the box.In fact, initial charging is a prerequisite for starting the system. Without connecting to the power source, the device controller blocks the display from turning on even if there is still energy inside.
In this article, we will take a detailed look at all the steps in preparing a tracker for operation, from physically connecting the charger to setting up in-app notifications, and learn how to properly install the gadget management software and what to do if standard activation methods fail.
Primary charge of the device
The fundamental step, without which it is impossible to start operating the Mi Band 4, is the connection to the power source. USB-The plug on one side and the contact pad with the tracker capsule on the other, you need to remove the tracker from the silicone strap, gently pressing the convex part of the capsule on the back side.
Once the module is removed, it should be inserted into the charger so that the contacts match. On the back of the capsule, you can see three golden contacts that should fit tightly to the answer pins inside. USB-Orientation matters: if you insert the tracker incorrectly, the charging won't go, and the screen will remain black.
⚠️ Warning: Do not put excessive effort into inserting the tracker into the charger.Mechanical damage to the contacts or capsule body can lead to loss of warranty and inability to further charge.
Once you've connected. USB-The battery animation should appear on the screen, and this is a signal that the power controller has activated and started taking current. 10-15 For a second, try to move the capsule slightly in the nest or wipe the contacts with dry cloth.
Installation and configuration of the Mi Fit application
The bracelet itself is only a peripheral device that does not have a full-fledged operating system for independent operation, and it requires a smartphone with the Mi Fit app installed (or Zepp Life, since the application was renamed), you can download the program from the official Google Play stores for Android or the App Store for iOS.
Once you install the app, you need to register for your Mi Account. This is a requirement of the Xiaomi ecosystem to synchronize health, step and sleep data between devices. Without authorization, you will not be able to log in to the pairing menu. When registering, use your current phone number or email address.
- 📱 Download the Zepp Life app (formerly Mi Fit) from the official store.
- 📝 Register with real data and region of residence.
- 🔐 Confirm the entry through the code from SMS or email.
- 📡 Turn on Bluetooth and geolocation on your smartphone before searching for your device.
It's important to note that the Android app requires permission to access geolocation to work properly, not to track your location, but a technical feature of Bluetooth Low Energy (BLE) in modern versions of the operating system, and without that permission, the phone simply won't see the bracelet signal.
💡
If the app can’t find the device, try to forcefully stop the Bluetooth process in your phone’s settings and run it again, or restart your smartphone.
The process of pairing the bracelet with a smartphone
Once the app is installed and logged in, move to the most important step, pairing. In the main menu of the Zepp Life app, you need to go to the Profile tab and select Add Device. From the list of available gadgets, select Mi Smart Band 4.
The system will start to look for nearby devices, at which point a pairing confirmation request or vibration signal may appear on the bracelet screen. If the bracelet screen is out, just tap it to activate it. The synchronization process takes no more than a minute with a stable connection.
After the successful connection, the smartphone screen will display a message about the completion of the setup. The bracelet vibrates, confirming the connection, and its display will display the current time, which will automatically be pulled from the network via the phone. From now on, the Mi Band 4 is considered on and ready for basic use.
⚠️ Warning: Don't try to pair the bracelet through the standard Bluetooth menu of your phone's settings. This will cause a connection error.
Update of firmware and calibration
Immediately after the first turn on, the system will offer a software update. It is not recommended to ignore this stage, since the factory version of the firmware may contain bugs or work incorrectly with new versions of the smartphone OS. The update improves the stability of the touch screen and the accuracy of the pulsemeter.
To update, go to the device profile in the app and click “Update Version.” The bracelet must be charged at least 20% and be near the phone. The process can take several minutes, during which the bracelet screen will go out and light up.
| Parameter | Description | Recommendation |
|---|---|---|
| Battery charge | Energy level for renewal | At least 20-30% |
| Distance | Distance between phone and bracelet | Not more than 1 meter |
| Internet | Necessity of the network for downloading | Stable Wi-Fi or 4G |
| Time of the process | Duration of installation of the software | 3-5 minutes |
After updating the firmware, it is recommended to calibrate the pedometer. Walk a known distance (for example, 100 meters) and check the data with the application. If there are discrepancies, you can enter your step length manually in the profile settings to improve the accuracy of measurements.
What to do if the update is suspended?
Configure notifications and functions
The main value of the tracker is the ability to receive notifications directly on the wrist. To enable this feature, you need to go to the device settings in the application and select "Application Notifications", where you can activate the display of messages from messengers, social networks and system calls.
Each app has a switch on the list, and it's important to understand that text will only show up if it's in a standard Android or iOS notification. Some apps may hide content for security reasons, so only the event signal will come on the wristband.
- 📞 Turn on incoming calls to skip calls without phone.
- 💬 Activate notifications for WhatsApp, Telegram, VKontakte.
- ⏰ Set up alarm clocks and tomato timer via app.
- 💓 Set the pulse interval for continuous monitoring.
You also need to look at the wrist-raising function to turn on the screen, which allows you to see the time and notifications with a simple hand movement, and the sensitivity of this function can be adjusted so that the screen does not light up with every hand stroke during a conversation.
Solving launch problems
Despite the reliability of the Xiaomi Mi Band 4, users may encounter situations where the device does not turn on even after charging. USB-Wipe the golden patches on the capsule with an alcohol napkin or a lastic.
If the bracelet shows the Mi logo and goes out immediately, it may be a damaged battery or a broken firmware, in which case, complete a reset through the app if it sees the device, or leave the bracelet on charge for several hours. Sometimes a deep discharge takes a long time to "rock" the battery.
☑️ Diagnosis of a faulty bracelet
In rare cases, cold treatment helps: some users note that placing a discharged bracelet in the refrigerator (in a sealed bag, without moisture!) before charging helped trigger the chemical processes in the battery.
⚠️ Warning: If the bracelet heats up while charging or emits an unpleasant odor, immediately disconnect it from the mains.This is a sign of an internal short circuit and a potential fire hazard.
Additional features and widgets
Once you have successfully turned on and set up, you can change the tracker’s dials, set goals by step, track sleep phases and stress levels. The Mi Band 4 also supports music management on your smartphone and has Find Your Phone.
Remember to sync the data periodically by opening the application so that the activity history is stored in the cloud, this will allow you to plot progress for a month or a year, and for advanced users, you can install third-party dials through special utilities.
💡
Regular synchronization and updating of the dials make the use of the bracelet more enjoyable and functional, turning it from a simple step counter into a personal assistant.
Use of the NFC-The bracelet version allows you to pay for purchases and use electronic keys, but these functions depend on the region of use and require additional configuration through the Mi Home application or payment services.
