Modern wearables have become an integral part of the digital ecosystem, allowing you to track physical activity and monitor health right from the wrist. The Xiaomi Mi Band 4C fitness bracelet is an affordable and functional device that requires the right initial setup to work fully. Without proper pairing with a smartphone, the tracker turns into a regular electronic watch with minimal functionality.
The activation process from Xiaomi takes only a few minutes, but requires a certain sequence of actions. The user needs to install specialized software that acts as a bridge between the bracelet and the phone’s operating system. It is important to note that the Mi Band 4C model is technically identical to the Redmi Smart Band, so the instructions for them are completely interchangeable.
In this article, we will take a look at all the steps of connection, from accessories preparation to fine-tuning notifications, how to avoid common synchronization errors and what Bluetooth settings are critical. Proper settings at start will ensure stable sensors and timely data acquisition.
Preparation for first inclusion and installation of the annex
The first step before setting up is to physically prepare the device. Take the tracker out of the box and remove all protective films from the screen and from the back of the pulse sensor. Charge the device to at least 20-30%, as gadgets often come with a minimum charge for long-term storage in stock. If the charging indicator does not light up immediately, try to wipe the contacts on the capsule with dry cloth.
Previously, the main tool was Mi Fit, but for new models and updated versions of firmware, Xiaomi is actively promoting the Xiaomi Wear app (formerly known as Zepp Life in some regions, but for the first time in the world). 4C It is better to focus on the current Xiaomi Wear or Mi Fitness. download should be made exclusively from official stores: Google Play for Android or App Store for iOS. APK-Files can lead to malware installation or unstable operation.
💡
When searching for an app in the store, pay attention to the developer: the official application for this series is often Xiaomi Wear or Mi Fitness, whose logo contains a stylized letter M or bracelet symbol.
Once you install the app, you need to register an account or log into your existing Xiaomi Account profile, which is a security requirement and a way to synchronize your statistics between different devices. Make sure that your phone has wireless modules, particularly GPS and Bluetooth, as without them, you will not be able to find the device.
- 📱 Download the official Xiaomi Wear or Mi Fitness app from the store.
- 🔋 Charge the bracelet at least 20% before first switching on.
- 📡 Enable Bluetooth and geolocation in your smartphone settings.
- 🆔 Register in the app using an email or phone number.
The process of pairing the bracelet with a smartphone
Run the app installed on your smartphone and go to the Add a new device section, usually the Profile button or the + icon in the upper right corner of the screen. In the list of available categories, select Bracelets or Wearables. The app will request permission to use Bluetooth and geolocation — confirm these actions, otherwise the scan will not begin.
Now, if you pick up the bracelet, if it's new, it should be in pairing mode automatically. If the device has been used before, you may need to reset the settings through the tracker's menu before the icon appears. QR-In the app, click on "Device Search" and wait for the name Mi Smart Band to appear. 4C Redmi Smart Band in the list of found gadgets.
⚠️ Note: Do not try to connect the bracelet directly through the standard Bluetooth menu settings Android or iOS. the pairing must occur strictly within the application, otherwise the functionality will be limited, and the synchronization of data will not work.
When the device name appears on the phone screen, click on it to start the mating procedure. The bracelet screen may have a pairing confirmation request or vibration signal. Once the device is successfully connected, the application will download the necessary firmware files and prompt you to update the tracker software to the current version, a step critical to fixing bugs.
☑️ Checking successful pairing
Setup of permissions and notifications
Once you've successfully connected, you can access personalization. Go to the device's in-app settings to select which notifications will come to your wrist. You can activate call display, SMS, messaging from messengers (WhatsApp, Telegram, Viber) and social networks. For each type of alert, you can adjust the vibration or turn it off completely.
Special attention should be paid to operating system permissions. Android often requires giving the application the right to “autostart” and work in the background so that the system does not “kill” the synchronization process to save energy. Without this step, you may not receive notifications if the application is folded. In the Settings menu → Applications → Xiaomi Wear, set the “No Limits” mode.
Also in this section, you can adjust the wrist lift to turn on the screen, the time format (12 or 24 hours) and the interface language. Support for Cyrillic helps you read messages in Russian without “cracose horns”, which is an important advantage of the 4C model over the very first versions of the brand trackers.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Background work | Allowed/No restrictions | Guarantees receipt of notifications |
| Geolocation | Always allowed. | Needed to search for the device and tracking |
| Bluetooth | On all the time. | Necessary for data synchronization |
| Screen notifications | Included. | Allows you to see text messages |
Sensor calibration and health monitoring
To accurately work the pedometer and activity tracker, you need to enter your anthropometric data. In the application profile, specify the current height, weight, age and gender. These parameters are used by algorithms to calculate calories burned and analyze sleep phases. If the data are incorrect, the statistics will be incorrect, which will reduce the value of the device as a fitness assistant.
The Mi Band 4C is equipped with an optical heart rate sensor. To properly operate the pulsemeter, it is important to snugly but not tightly fit the bracelet to the skin. Too weak fit will lead to light and erroneous readings, and too strong will cause discomfort. Periodically wipe the back of the device from sweat and dirt to ensure that the measurements are clean.
You can adjust the automatic pulse rate in the app, from a lean mode (every 30 minutes) to a monitoring mode of every minute. SpO2 activation is also available, but it consumes battery power faster. For the initial calibration, it is recommended to spend a few days in normal mode so that the device learns your habits.

Dial management and personalization
One of the favorite features of users is changing dials. The built-in store in the app offers hundreds of options, from classic hand-helds to complex information with many widgets. You can choose a free option or purchase a premium design. Installation takes a few seconds and takes place over the air.
In addition to ready-made solutions, many users prefer to create their own dials. The "Create your own dial" feature allows you to upload personal photos from your phone, change the time font, background color and location of elements (date, steps, weather), which makes your gadget unique and allows you to customize the interface to specific needs, for example, to display a large time or only a pulse.
Remember, complex animated dials consume more battery power. If autonomy is important to you, opt for static images with minimal active elements. Balance between beauty and battery life is key to customizing your look.
- 🎨 Use the “Create Your Dial” function for uniqueness.
- ⚡ Static images are more economical to consume battery power.
- 🌤️ Weather widgets require included GPS and the Internet on the phone.
- 🔄 Check the Dials section regularly for new updates.
Solutions to Connection Problems
Even with all the instructions, there are sometimes technical difficulties. The most common problem is that the phone does not see the bracelet. In this case, make sure that the device is not connected to another smartphone. The Mi Band 4C can only broadcast a signal for one active connection. If the bracelet was previously tied to another phone, you must reset through the bracelet menu (Settings → Reset / Unbind) or remove the device from the application on the old phone.
Another common situation is a connection break or a lack of data synchronization, often solved by rebooting both devices: turn off and turn on Bluetooth on your phone, and the bracelet reboot via the menu or decharging. Also check whether the application is not on the list of “cooled” or “cleaned” in the Android system, as aggressive energy savings can block its operation.
⚠️ Warning: If the bracelet has stopped responding to the pressings and does not turn on, put it on the charger on the 15-20 Deep discharge of lithium polymer battery takes time to "swing" before turning on the screen.
In rare cases, removing the application completely, clearing the Bluetooth cache in the system (via the developer menu or app settings) and re-installation can help. If nothing helps, there may be a problem in the hardware of the Bluetooth module of the bracelet itself, and then you will need to contact the service center.
💡
90% of connection problems are solved by completely removing the device from the phone’s Bluetooth list and re-associating it exclusively through the app.
