Restoring the Xiaomi Mi Band 4 fitness tracker after completely resetting is a procedure that can seem difficult only at first glance. Users often face a situation where the device “forgets” previous pairings and stops responding to smartphone commands. This is standard behavior for wearable electronics after performing a Hard Reset or factory reset command.
To successfully reset the device, you will need not only the tracker itself, but also a stable Internet connection, as well as a properly working companion application. It is important to understand that resetting the settings completely cleans the internal memory of the bracelet, removing all user data and Bluetooth settings, which is why the connection process must be re-enabled, as when the device is first turned on.
In this guide, we will take a detailed look at the algorithm to avoid common synchronization errors, learn how to properly prepare your smartphone, which software to choose and what to do if the system does not see the device in range.
Preparation of the smartphone and choice of application
The first step before trying to pair is to install or update specialized software. Mi Band 4 has long been the main application Mi Fit, but Xiaomi is gradually moving users to the Zepp Life platform. Both programs are functionally similar, but can work differently with new versions of the Android and iOS operating systems.
Make sure your smartphone has the necessary communication modules on it. Active Bluetooth and preferably geolocation enabled are required for the tracker to work smoothly (GPS), In modern versions of Android, it is a requirement for search. BLE-Without permission to access the location, the application may not see the bracelet in the list of available devices for connection.
- 📱 Download the official Zepp Life or Mi Fit app from Google Play or the App Store.
- 🔋 Check the bracelet charge – it must be at least 20% for a successful procedure.
- 📶 Make sure your smartphone is connected to Wi-Fi or has stable mobile internet.
- ⚙️ Turn on Bluetooth and allow the app to access geo-position in your phone settings.
⚠️ Note: If you have Mi Fit and you have used it before, try updating it first. If the update doesn't work or the app doesn't work properly, uninstall it and install Zepp Life, as support for older versions of the software is gradually being phased out.
After installing the application, you need to register or log into your Mi Account. This is critical, since all health and activity data is stored in the cloud. If you plan to use an old account, make sure you remember the password, otherwise data recovery will not be possible. For a new device or after a deep reset, it is often recommended to create a new account to avoid sync conflicts.
Discharge process and interface
Before you start searching for a device, you need to make sure that the Xiaomi Mi Band 4 is really in standby mode. After resetting the settings on the tracker screen, the tracker usually appears. QR-If the screen is on a dial, it means that the reset is not completed or the device is already paired with someone else.
Forced entry into search mode on the bracelet itself often requires a sequence of actions. In some cases, just wait until the device goes to sleep, and then touch the touch button to wake up. If the bracelet is “hang” and does not respond, it may require charging for 10-15 minutes to activate the power controller.
☑️ Bracelet ready to connect
It's important to note that the pairing mode on the Mi Band 4 is not permanent. If you don't search through your phone for a long time, the monitor screen will go out and it will go into energy-saving mode, in which case the app will not be able to detect the device, so all the search actions should be done immediately after the bracelet screen wakes up.
Step-by-step instructions for synchronization
The process of connecting Xiaomi Mi Band 4 after reset requires attention to detail. Open the installed application (Zepp Life or Mi Fit) and go to the user profile. At the top of the screen or in the Profile menu, find the Add Device or + button. The application will start scanning the Bluetooth space.
At that point, a list of available devices should appear on your smartphone screen. Look for a name that starts with Mi Band 4 or Mi Smart Band 4. Don't confuse it with other Xiaomi devices if you have them at home. Once you see the right name, click on it. On the bracelet screen, you may see a request for confirmation of pairing - tap the touch area for confirmation (the tick icon or phone).
What if the code doesn't match?
Once confirmed, the setup process will begin on both devices. The application may suggest updating the firmware tracker. This is a must-have: without the current version of the software, the bracelet may not work stable or display some notifications. Wait until the download and updates are completed without turning off the smartphone screen and holding the bracelet nearby.
💡
Keep the bracelet and phone no more than 30-50 cm apart during a firmware update. Interrupting communication may lead to the need for a reset.
Set up notifications and permissions for Android
Successful connectivity is only half the battle. For the Mi Band 4 to function properly, you need to configure access rights in the smartphone operating system. Modern versions of Android (10, 11, 12 and above) have aggressive energy saving algorithms that can kill the application's background process, which causes the bracelet to stop receiving notifications and pulse data.
You need to go to your phone's settings, find the Apps section, select Zepp Life (or Mi Fit) and open Battery or Energy Saving. Select No Limits or No Limits mode. Contacts, SMS, call log and location must also be activated in the permissions section.
| Type of permit | Status | Why do you need it? |
|---|---|---|
| Location (GPS) | Always allowed. | For Bluetooth scanner and route tracking |
| Contacts and calls | Permitted. | To display the name of the caller on the bracelet |
| Auto-start | Included. | To make the application work immediately after turning on the phone |
| Notifications | Permitted. | To transfer fluffs from messengers to a tracker |
Once you have access rights set, check the notifications, send yourself a test message or call from another number, if there is a vibration and the screen lights up, the setup was successful, and if not, check if the bracelet has Do Not Disturb mode (moon icon), which blocks all alerts.
Solving the visibility problems of the device
Quite often, users are faced with the situation where the application says "Device not found" even though the bracelet is on and nearby.This may be because the phone "remembers" the old pairing Xiaomi Mi Band 4 and tries to connect directly through the system Bluetooth, bypassing the application.
To fix the problem, go to your smartphone’s Bluetooth system settings. Find the Mi Band 4 devices you previously connected to and click “Forget this device” or “Unpair it.” Only then go back to the Zepp Life/Mi Fit app and repeat the search. A full smartphone reboot also helps, which clears the Bluetooth stack cache.
⚠️ Warning: Never try to connect the bracelet solely through the Bluetooth menu of your phone's settings. The pairing must occur strictly within the companion app, otherwise the data synchronization will not work.
If the problem persists, check if the bracelet is connected to another phone. Mi Band 4 can communicate with only one active device at a time. If you change your phone, be sure to remove the bracelet from the application on the old device or perform a reset (which you, by the condition of the task, have already done). Sometimes it helps to install third-party utilities, such as Notify for Mi Band, which can "wake" the communication module, but for normal work it is better to use official methods.
💡
The main reason for connection problems is residual entries in the phone’s Bluetooth memory, and always remove the device from the system list before re-searching the app.
