Modern fitness trackers have become an integral part of the lives of those who monitor health and physical activity. - Xiaomi Band model 4C It is a great budget solution that combines a bright AMOLED-screen and extensive monitoring functionality, but before first use, the device requires the correct initial setup and synchronization with the smartphone.
The process of activating a gadget can seem confusing to beginners, especially given the company’s transition to new software platforms. In this article, we will discuss all the steps from unpacking to the first data synchronization, you will learn which application to choose, how to avoid typical errors when pairing Bluetooth and what settings should be changed immediately after turning on.
If you install all the components correctly, you'll keep the notifications running smoothly and the pulse rates being recorded, and if you follow the steps carefully, you'll avoid any problems with future connection loss, so let's start looking at the connection in detail.
Preparation for first on and charging
Before trying to connect the tracker to the phone, you need to make sure that the device battery has enough charge. Often new gadgets go on sale with a partially discharged battery, which can lead to the inability to turn on or unstable operation of the Bluetooth module. Xiaomi Band 4C comes with a special charging cable that needs to be removed from the box along with the main unit.
The charging process does not require a connection to a computer, just use any power adapter with a current of 1A or higher. Insert the connector into the corresponding connector on the tracker body before the characteristic click.
⚠️ Warning: Do not use chargers with support for fast charging technologies above 18W as this may damage the tracker's power controller. USB-5-volt port.
It is recommended to leave the device on charge for at least 15-20 minutes before the first activation attempt, which will allow the system to perform an initial calibration of the sensors. If the screen does not catch fire immediately, wait a few minutes - sometimes a deep discharge takes time to "pump" the lithium polymer element.
Make sure your smartphone has a wireless module enabled. The Mi Band 4C requires Bluetooth version 5.0 or later to work smoothly, although the device is compatible with older versions of the protocol. Also check that geolocation (GPS) is enabled in the phone's settings, as modern versions of Android require this resolution to search for Bluetooth devices.
Selecting and installing the right application
The key to the setup process is choosing the software. Unlike older models that worked through Mi Fit, the Xiaomi Band 4C requires a more modern app called Mi Fitness (formerly known as Zepp Life in some regions, but Mi Fitness is recommended for 4C), which can be downloaded from official Google Play or App Stores.
Once you download the installation file, run the installation. The application will request a number of permissions to access health, location and notification data. To properly work all the functions of the tracker, you must provide all the requested permissions at once, otherwise the synchronization of sleep or step data may be interrupted.
When you first start up, you will be asked to create an account or log in through an existing one. Supports login methods through phone number, email, and Xiaomi, Google and Apple accounts. It is recommended to use the same account that is already used on other devices of the brand to combine all the statistics in one profile.
After successful authorization, go to the Profile or Device tab. The system automatically prompts you to add a new device. If the automatic search fails, select the Add Device option manually and search the Mi Smart Band 4C list.
The process of pairing through Mi Fitness
When the app is ready to go and the tracker is charged, you can start pairing directly. Come closer to the smartphone, the distance should not exceed one meter. Open the Mi Fitness app and press the add device button in the upper right corner of the screen.
The Mi Band 4C should appear on the list of available devices. Click on the model name. The confirmation code will appear on the tracker screen and on the smartphone display. Check the numbers and click "Confirm" or the checkmark on the bracelet. This is necessary to protect against unauthorized connection to your device by unauthorized persons.
☑️ Checklist of successful pairing
When you connect, the app may suggest that you update the firmware of the device, and it is strongly recommended that you agree to this action, even if it takes 5-10 minutes, and new versions of the software correct communication errors and improve the performance of pulse sensors.
During the update, don't move away from your phone or press the buttons on your wristband. The tracker screen can go out and light up again, which is normal for flashing. Once you've finished, the device will reboot and you'll see a welcome screen with the brand logo.
Profile setting and personalization
Once the connection is successful, the fine-tuning phase begins, and the app will ask you to enter anthropometric data: height, weight, date of birth and gender. These parameters are critical for algorithms that calculate calorie expenditure and analyze sleep phases. Don't ignore this step, otherwise the statistics will be inaccurate.
Then you set your activity goals, you can set your daily step rate, like 10,000 or 15,000 steps, and you can set up your sedentary reminders to make the tracker vibrate if you haven't moved for a long time.
| Setup parameter | Recommended value | Impact on work |
|---|---|---|
| Wrist lifting | VL (08:00 to 22:00) | Saves battery at night |
| Pulse monitoring | Every 10 minutes. | More accurate statistics |
| Notifications | Only important applications. | Reduces the number of vibrations |
| Language of the system | Russian/English | Menu readability |
In the Dials section, you can choose the look of the screen. Xiaomi Band 4C supports installing thousands of third-party dials from the online store. Choose one that displays the widgets you want, such as the weather or current heart rate.
💡
Set a “Do Not Disturb” schedule for sleep (e.g. 23:00 to 07:00) so that notifications don’t wake you up with vibrations in the middle of the night.
Working with notifications and functions
One of the main functions of the tracker is to display notifications. In the Mi Fitness app, go to the "Application Notifications" section. Here you will see a list of all the programs installed on the phone. Activate switches only for those messengers and social networks that are really important, so that the device is not overloaded with constant vibrations.
Note that the text of messages is displayed only if it came after the bracelet is connected. Old messages will not sync. To correctly display the Cyrillic alphabet, make sure that the language settings of the device are Russian.
⚠️ Note: For Android smartphones, for notifications to work smoothly, you need to fix the Mi Fitness app in memory and prevent the system from closing it to save energy.
You can also activate stress monitoring, breathing exercises, and women's health cycles in the feature menu, each of which requires periodic use to accumulate statistics, such as putting a bracelet firmly against your wrist to measure stress and not moving your arm for 30 seconds.
Solving Typical Connection Problems
Sometimes the setup process can go wrong. If you can't find a device on the list of available devices, try restarting your smartphone. Often the problem lies in the hung Bluetooth module of the operating system.
If the bracelet was previously connected to another phone, it may not be detected by the new device, in which case you need to reset the tracker settings. Go to the bracelet menu, find System or Additional and select Reset, and then the device will be visible for search again.
What to do if the firmware update is suspended?
If the app sees a device but writes “Connection Error,” remove the tracker from the list of paired devices in the phone’s Bluetooth settings. Then re-run the search inside the Mi Fitness app.
💡
90% of connection problems are solved by completely removing the device from the phone’s Bluetooth memory and re-binding it through the Mi Fitness app.
