The first introduction to a new gadget often begins with confusion, especially when the device does not respond to simple touches of the screen. Owners of the popular activity tracker Xiaomi Mi Band 4 often face a situation when the screen remains black after being removed from the box. This is not a sign of breakdown, but the standard logic of energy-efficient devices.
To activate a wearable device, you need to perform a series of sequential actions that will trigger the system power controller. It is important to understand that there is no button on the body of this tracker, and control is carried out exclusively through the touch panel and the application on the smartphone. For initial activation, it is critical to have a charge in the battery, so connecting to the charger is the first necessary step.
The launch process involves not only physical network connectivity, but also software initialization via a mobile app. Without a link to the phone, the bracelet will remain in standby mode even if the charge indicator shows a full battery. Below we will discuss in detail each step, from unpacking to fine-tuning notifications.
Preparation for the first launch and charging
Before you try to turn on the device, you need to make sure that it is ready for operation. A complete tracker usually has a partial charge, but it may not be enough to fully start the system and perform the initial setup. Connect the bracelet capsule to the charger using a special cable from the kit. The indicator on the screen should light up, showing the current level of charge.
If the screen doesn't start immediately, don't panic. Sometimes the contacts on the back of the capsule may be oxidized or covered with a protective film. Wipe them with dry soft cloth and press them tightly against the charging dock. The charging process can take anywhere from 30 minutes to 2 hours depending on the degree of discharge of the lithium polymer battery.
💡
If the charging indicator does not light up, try to slightly move the capsule in the docking station or wipe the contacts with an alcohol wipe to remove the factory lubricant.
While charging, the device may heat up slightly, which is normal for physical processes. However, if the heating seems excessive, it is better to disconnect the gadget from the network and let it cool. Once the icon of the full battery appears on the screen or the percentage of charge exceeds 80%, you can proceed to software activation.
Installation and configuration of the Mi Fit application
The main tool for managing the tracker is a mobile application. It was formerly called Mi Fit, but in new versions of Android and iOS functionality was transferred to the Zepp Life application. APK-files, as they may contain malicious code or work incorrectly with synchronization protocols.
Once installed, you need to register an account, whether it's a Xiaomi account, Google account, or social media login, and you need to register to save your health statistics and customize your profile, and you need to specify real data on your app: height, weight, date of birth, because algorithms use them to calculate calorie expenditure and other activity metrics.
An important step is to provide all the necessary permissions. The app will request access to geolocation, Bluetooth, notifications and background work. Without a geolocation permission in Android, it is often impossible to detect the device when searching. Without a background permission, notifications may stop coming if you fold the application.
Interconnection of the bracelet with a smartphone
The pairing process requires you to turn on the Bluetooth module on your smartphone. Go to your phone's settings and make sure the wireless networks are activated. Don't try to connect the bracelet through the standard Bluetooth menu in your phone's settings like a regular headset. The pairing should be done strictly through the application interface.
Launch the app and go to the Profile tab. Click on Add Device and select Bracelet category. The system will start searching for available devices within range. When the name Mi Band 4 appears on the screen, click on it to start the binding procedure.
☑️ Pre-conjugation check
The bracelet screen and smartphone screen may display confirmation codes, make sure they match, and confirm the action with vibration or touch. Once successfully connected, the tracker automatically synchronizes the time and date, and also prompts you to update the firmware.
⚠️ Warning: If the device search lasts too long, try rebooting your smartphone.In rare cases, the phone's Bluetooth module cache may prevent new gadgets from being discovered.
Update of firmware and basic settings
Once connected, the app may suggest a software update, an important step as newer versions of firmware fix bugs, improve connection stability, and add new dials. The upgrade process can take anywhere from 5 to 15 minutes, during which the bracelet must be near the phone.
In the bracelet settings in the app, you can change the interface language, the time format (12 or 24 hours) and the units of measurement (metric or imperial system), also adjust the brightness of the screen and the time of its activity after lifting the wrist, the function of raising the wrist allows you to save charge, turning on the backlight only at the right time.
| Parameter | Description | Recommendation |
|---|---|---|
| Brightness | Screen glow level | Medium or Auto |
| Vibration. | The power of tactile response | Average (for savings) |
| Dial | Screen appearance | User choice |
| Goals of steps | Activity rate per day | 8000-10000 stepping-step |
Don't ignore setting activity goals. A well-defined step rate motivates you to move more, but it shouldn't be unattainable. The tracker's algorithms will compare your daily performance to a set value and signal that you're vibrating your goal.
Set up notifications and health features
One of the main functions of a smart wristband is to display notifications, and in the app you can choose which apps will duplicate messages on your wrist, which can be calls, SMS, messages from messengers, email clients and social networks.
For each type of notification, you can configure the display, for example, for calls, you can display the contact name (if it is in the phone book) and the ability to reject the call with vibration. For messages, only preview text is available, you can not send a response from the bracelet.
The secret of setting up notifications
The health monitoring functions deserve special attention. The tracker can measure the pulse, analyze sleep phases and count steps. The pulsemeter must fit the wrist tightly to the wrist to work properly. The application can adjust the frequency of measurements: continuous monitoring consumes the battery quickly, so you better choose an interval mode.
Solution and resetting of settings
During operation, there may be situations when the bracelet stops responding to commands or loses communication with the phone. In such cases, reset helps. Since there is no off button, you need to find the "Untie" item in the application, and then select a reset in the settings of the bracelet itself (if it reacts).
If the screen doesn't respond to touch, you can try putting the bracelet on charge. Connecting to the network often forcibly restarts the system. If that doesn't work, there is a "deep discharge" method where the device is left to zero for a few days and then charged to 100%.
⚠️ Warning: Do not attempt to open the capsule body or heat it, this will cause permanent leakage damage and failure of electronics.
In the extreme case, when the software methods don't work, you can use the full reset function in the application, which will delete all the data from the device and return it to the factory settings, and then you have to go through the setup procedure again.
💡
In 90% of cases, problems with the work of the bracelet are solved by a full reboot of the smartphone and re-pairing through the application.
