Activating a new wearable gadget is a process that often raises questions among users accustomed to classic electronics.The Xiaomi Mi Band 4 fitness bracelet does not have a physical on button, which can be confusing on first acquaintance.The device is in deep sleep mode immediately after being removed from the box and requires certain actions to "wake up" the system.
Proper start-up ensures that all sensors work correctly, that the smartphone is connected to the device and that the measurements are accurate in the future, and in this article we will discuss in detail the activation, pairing and initial setup algorithm of the Mi Band 4, as well as the typical errors that occur at the start of the tracker use.
Primary activation and activation of the device
The main feature of the fourth generation of the popular tracker from the Chinese giant is the lack of a mechanical power switch, which is done to increase the moisture protection of the case and increase the battery life. To bring the device out of its resting state, you need to connect it to the energy source, to do this, remove the capsule (tracker) from the silicone strap and insert it into a special charging dock.
After connecting to USB-The port of the computer or the adapter of the smartphone will display a charging animation on the screen, and then a welcome message. The charging process is not only a way to replenish energy, but also a signal to the controller to start working. If the screen doesn’t catch fire within a minute, check the contacts on the capsule and charger – they should be clean and fit tightly together.
⚠️ Warning: Do not try to turn on the bracelet by repeatedly pressing the touch area of the screen. This will not lead to the result, since the program reset or turn on is possible only through the application of voltage or a program signal from the smartphone.
After the Mi logo appears, the device is considered on and ready for further manipulation, you can now insert the tracker back into the strap and proceed to install the software. It is important to understand that without first charging (at least for 10-15 minutes), the bracelet can behave unstable when you try to pair.
💡
Before the first activation, it is recommended to charge the device to 100% to avoid sudden shutdown during the installation of important system updates.
Installation and configuration of the Mi Fit application
The main tool for managing the bracelet is the mobile application. At the moment, the Mi Band 4 application Mi Fit (renamed Zepp Life in some regions) is the most stable, you can download it from official Google Play stores or the App Store. It is not recommended to use third-party modified versions of programs, as they may incorrectly transmit health data.
Once you install the app, you need to create an account or log into an existing Xiaomi account, which is a mandatory requirement for data synchronization. During the registration process, specify the correct data: height, weight and date of birth, since these parameters determine the accuracy of the calculation of steps and calories burned by the tracker algorithms.
In your profile settings, be sure to include app notifications, geolocation, and Bluetooth access. Without these permissions, finding your device may take a long time or not be successful. Also make sure your smartphone is Bluetooth enabled and doesn’t have old saved copies of your bracelet on the list of available devices.
Interconnection of the bracelet with a smartphone
The process of pairing is the most important step. Open the Mi Fit application, go to the Profile tab and click Add Device. From the list, select Mi Band 4. The application will start scanning the space. At this point, a request may appear on the bracelet screen to confirm the pairing with a vibration or graphic symbol.
Tap the touch button on the bracelet for confirmation. If the code on the smartphone screen matches what is displayed (or implied) on the tracker, the connection will be established. Data synchronization will begin automatically, and the time on the bracelet will be updated according to the time in the phone.
☑️ Checklist of successful pairing
Sometimes the phone sees the device but can’t complete the connection, in which case it helps to reboot Bluetooth on the smartphone or completely reboot the bracelet itself through the settings menu in the application. Remember that the Mi Band 4 can only pair with one smartphone at a time.
Update of firmware and language package
Immediately after the first connection, the app will offer to update the software, which is a critical step: the factory firmware may contain errors or not have support for Russian, which will make the use of the device uncomfortable, the update installs current language packages and fixes sensor bugs.
The upgrade process takes 5 to 15 minutes depending on the version, at which time the bracelet screen will show the progress bar, and the smartphone should be in close proximity (no more than 1-2 meters), interrupting the process can cause the device to stop responding to commands.
⚠️ Note: It is strictly forbidden to turn off Bluetooth or close the application during a firmware update.This can turn the bracelet into a "brick", the recovery of which is possible only through a service center or complex engineering manipulations.
What to do if the update is suspended?
After a successful update, check for Russian in the bracelet menu. To do this, go to the device settings in the app and find "Language." If Russian is not on the list, you may need to update the dial or reflash the device by selecting "Russia" in the account settings.
Configuring the interface and dials
One of the key features of the Mi Band 4 is color. AMOLED-You can use a screen that allows you to set colorful dials. The Mi Fit app has an extensive dial store (Store) where you can download new designs. To install, just select your favorite and click "Install".

|---|---|---|
| Wrist lifting | Turning on the screen when raising your hand | High. |
| Notifications | Vibration in calls and messages | Average. |

💡
Customizing the widgets displayed and disabling unnecessary notifications is the best way to increase the battery life of the device to 10-12 days.
Solving problems at launch
Despite the simplicity of the device, users can face difficulties. Often the bracelet is not visible in the Bluetooth search, this is solved by clearing the cache of the Mi Fit application in the Android settings or completely removing and re-installing the application.
Another common problem is incorrect step counting or sleep, and this is solved by calibration: walk a known distance (e.g., 100 meters) with your phone in your hand, compare the data, and then reset the statistics in the application, sometimes requiring a complete reboot of the bracelet system through the Break the Couple menu and re-pair.
⚠️ Attention: If the bracelet stopped vibrating or the screen went out and did not respond to charging, a deep discharge may have occurred. 2-3 Even if the indicator does not immediately light up.
In rare cases, the problem lies in the incompatibility of OS versions. Make sure your smartphone runs Android 5.0/IOS 10.0 or higher. Older versions of operating systems may not support the modern encryption protocols used by the Mi Fit app.
