Today’s wearables have become an integral part of the lives of many users who want to control their activity. Connecting Xiaomi Mi Band 4 C to a smartphone is the first and most important step to get started with the device. The pairing process takes only a few minutes, but requires care, since the bracelet does not work independently without a bundle with a mobile application.
Proper initial synchronization settings ensure that notifications work consistently and steps are counted accurately. If you miss important registration steps in an app, the tracker can display the wrong time or not transmit sleep data. In this article, we will discuss in detail the process of installing software and creating pairs between gadgets.
Preparation for the first launch of the tracker
Before trying to tie the devices, make sure the bracelet battery is charged. Although new gadgets often come with a partial charge, long-term storage in stock could completely drain the battery. Connect the tracker to the charger that comes with it, and wait for the welcome screen or charging indication to appear.
The second important step is to prepare the smartphone itself. The Mi Band 4 C requires Bluetooth enabled and internet access for initial registration, and it’s also worth checking the operating system version: Android requires version 4.4 and higher, and iOS requires version 9.0 and higher.
Make sure that geolocation is allowed in the phone settings. This seems odd for a fitness bracelet, but Bluetooth Low Energy protocols on Android require access to location to scan nearby devices. Without that permission, finding a tracker may be unsuccessful.
⚠️ Warning: Do not try to connect the bracelet directly through the standard Bluetooth menu in the phone settings.This will cause a pairing error and the device will become unavailable for the application.
Clear the list of previously paired devices if you have already tried to connect the bracelet and the process is interrupted. Go to Settings → Bluetooth, find the Mi Band 4 C or Mi Smart Band list and click Forget or Undo pairing.
Installation and configuration of the Zepp Life app
The main software to work with this generation of trackers is the application Zepp Life (formerly known as Mi Fit), it must be downloaded from the official store: Google Play for Android or App Store for iOS. APK-Files can lead to unstable work or data theft.
Once installed, launch the app and log in to your account. You can use your existing Mi Account, email address, or log in via social networks like Facebook or Google. Creating an account is necessary to store your activity history in the cloud.
When you first log in, the app will request access to various system functions. It is critical to allow access to notifications, contacts and, as mentioned earlier, geolocation. Without these permissions, the smart wristband will be severely limited.
💡
If Zepp Life doesn’t see the bracelet, try installing Mi Fitness, which is becoming the main app for device management in some regions and for new firmware.
The process of pairing the bracelet with the phone
Now, to the direct device connection, go to the Profile tab on the Zepp Life app's main menu, and at the top of the screen you'll see the Add Device button. Click on it and select the Bracelet category list.
The app will start searching for available devices, at which point a request for confirmation of vibration pairing may appear on the tracker screen. If the screen is out, just tap the touch button on the bracelet to wake it up.
When the Mi Band 4 C appears on the list of devices found, click on its name. Confirmation codes will appear on the smartphone screen and on the bracelet display. Make sure they match, and confirm the action by clicking the tick on the tracker.
- 📱 Make sure your phone is no more than 1 meter away from the bracelet.
- 🔋 The tracker charge must be above 20% for stable profile updates.
- 📶 Wi-Fi connection is desirable to have stable for fast loading of dials.
- 🔄 Do not switch between applications during the mating process.
Once confirmed, the time synchronization process and profile adjustments will begin, at which time the progress bar can be displayed on the bracelet screen, and interrupting this process can cause the clock to show the wrong time.
☑️ Checking a successful connection
Configure notifications and functions
Once successfully connected, you need to set up notifications to make the bracelet vibrate when incoming calls or messages. In the Zepp Life app, go to Profile, select your Mi Band 4 C, and find Application Notifications.
Here you'll see a list of all the apps installed on your phone, activate the switches next to the apps you want to be notified of, which could be messengers, social media, or email clients.
It is important to note that for notifications to work, the Zepp Life app must have constant access to work in the background. Android operating systems often “kill” background processes to save energy, which leads to the disappearance of notifications on the bracelet.
⚠️ Note: Xiaomi, Huawei and Samsung phones need to manually add the Zepp Life app to the power saving exception list (“Sunset” or “Do Not Limit”), otherwise notifications will arrive with a delay.
You can also set the time format (12 or 24 hours), raise your wrist to turn on the screen, and set activity targets, and all changes are applied instantly after you press the sync button.

Solving Common Connection Problems
Sometimes the setup process can go awry. If the phone can't see the bracelet, try restarting both devices. Often the problem lies in the smartphone's hung Bluetooth module, which stops scanning the environment correctly.
If the bracelet appears on the list but the connection is reset, check if the tracker is connected to another phone.Mi Band 4C can only store one active connection in memory.To change the phone, you need to untie the device in the application on the old gadget.
The table below shows the main error codes and how to solve them:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Search for the device... (long) | Geolocation off. | Turn on GPS in your phone settings |
| The pairing error | The bracelet is occupied by another phone | Untie in the application on the old device |
| No notifications. | Application closed by system | Allow auto-start and work in the background |
| Time is not updated. | No internet at launch | Open the application with an active network |
If nothing works, reset the bracelet completely to factory settings. In the tracker menu, find the System section (the gear icon) and select "Sever a pair" or "Reset." After that, you need to start the connection procedure again.
💡
90% of connection problems are solved by completely removing the device from the phone’s Bluetooth memory and reinstalling the Zepp Life app.
Update of firmware and dials
Immediately after the connection, the application may suggest updating the tracker software. The firmware contains bug fixes and new features. It is recommended to always agree to an update by connecting the phone to Wi-Fi for quick download.
The upgrade process takes 5 to 15 minutes, and the screen will be on, showing the execution rate, and don't go far away from the phone and try to use the bracelet until the process is complete.
Also worth a look at the dial store. There are plenty of free and paid screen designs available for the Mi Band 4 C. Downloading a new dial is a great way to check the stability of a Bluetooth connection, as files can be voluminous.
- ⌚ Secondhand dials put the battery faster.
- 🎨 Animated dials require a newer version of the firmware.
- 📉 After updating the firmware settings can be reset to standard.
Regularly checking updates in the app ensures that your gadget is working as efficiently and safely as possible.Manufacturers periodically release patches that improve the accuracy of the pulse sensor.
