The situation where Mi Band 4 suddenly loses communication with the phone or requires reconfiguration after resetting is quite common. This can happen after a firmware update, a change in the smartphone or a system glitch of the operating system. Users often panic, believing that the device is out of order, but in most cases the problem is solved by the correct sequence of actions to reconnect.
The process of reconnecting does not require complex hardware or in-depth knowledge of IT. All you need is a fitness bracelet itself, a charged smartphone with the Mi Fit (or Zepp Life) app installed, and a little patience. It is important to understand that after resetting the tracker goes into standby mode, becoming visible to other devices, but not in a hurry to automatically connect to the old profile.
In this article, we will discuss in detail each step of restoring your gadget. We will look at the nuances of cleaning the Bluetooth cache, the features of working with the profile in the application and methods for solving typical mistakes that occur when trying to “friend” a fitness tracker and a smartphone again.
Preparation of a smartphone and bracelet for pairing
Before you try to reconnect the Mi Band 4, you need to make sure that both devices are in the correct state. Often the cause of failure is the “junk” in the phone’s Bluetooth buffer or the frozen process in the background. Start by checking the battery charge of the tracker – if it is discharged to zero, it may not be signaling.
On your smartphone, you should pre-clean the list of conjugate devices. Even if you don't see the bracelet in the active list, its "trace" may have remained in the system. Go to the standard Android or iOS settings, find the Bluetooth section, and if there is a record about the Mi Band 4, click "Forget the device" or "Untie".
⚠️ Warning: Do not try to connect the bracelet directly through the standard Bluetooth menu of your phone settings.This will lead to a pairing error, since the device is completely controlled by the Mi Fit app, not the Android system.
It's also important to make sure that geolocation (GPS) is enabled on the phone. In modern versions of Android, it's a mandatory requirement for Bluetooth Low Energy (BLE) to work, which is used in Xiaomi trackers.Without the GPS enabled, the app simply won't see the tether device.
💡
Before starting the procedure, restart your smartphone – this will reset all temporary network conflicts and increase the chances of a successful connection the first time.
Data cleanup of the Mi Fit application and re-binding
If a simple reconnection doesn’t work, you need to clear the data of the intermediary application itself. Often, errors accumulate in the user profile that prevent correct synchronization. To do this, go to the application settings on your phone, find Mi Fit (or Zepp Life) and select “Clear Data” and “Clear Cache”.
Once the data is cleared, the app will return to the “as after installation” state, you will need to re-enter the username and password from your Xiaomi account. This is normal, your steps and training data are stored on the server and will be downloaded after authorization.
Now you can start adding a device. In the main menu of the application, go to the profile (the Profile tab in the lower right corner) and select "Add device." In the list, find Mi Band 4. The application will start searching.
- 🔍 Make sure the bracelet is near the phone (no further). 1-2 meters).
- 📱 Keep your smartphone screen on during the search process.
- 🔄 If the search goes on too long, try turning off and turn on Bluetooth on your phone.
When the app detects the tracker, a pairing request will appear on the screen, a vibration may appear on the bracelet screen and a request to confirm the action (touch the touch button), and the process of synchronizing time and settings will begin after confirmation.

Solving Bluetooth and device visibility issues
Sometimes it happens that the application simply does not “see” the Mi Band 4, even though the bracelet is on, this can be due to the fact that the tracker “hangs” in standby mode or lost the radio module in a software failure, in which cases you need to rigidly restart the bracelet itself.
Put the tracker on charge. Connecting to the power supply automatically restarts the device. Once the "Mi" logo appears on the screen, try running the in-app search again. Often this simple step solves 90% of the invisibility problems.
Why is the bracelet not visible to other phones?
If the problem persists, check if the bracelet is connected to another phone.The Mi Band 4 can only store data about one active connection at a time.If you used it with another smartphone before and didn't untie it in the app, the new phone won't be able to connect.
In rare cases, resetting the network settings on the smartphone itself helps, which will delete all stored Wi-Fi passwords and Bluetooth pairings, but often effectively “cures” software errors of the communication module.
Creating a new profile or entering an existing one
The important thing when you reset your work is to choose an account strategy, so you can either log in to an old account or create a new one, and each method has its own characteristics that you should consider.
Logging into an old account saves your entire activity history if it was synced before reset. However, if there were errors in the profile, they can move to a new session. Creating a new profile is a blank slate, but you lose your accumulated achievements and step history.
When you create a new profile, the system may require you to reconfigure all notifications, step goals, and alarm settings, which will take longer, but ensures that there are no program conflicts, and the choice depends on how critical your past workout history is.
| Parameter | Old account. | New account |
|---|---|---|
| History of steps | Retained (in synchronization) | Starting from scratch. |
| Notification settings | Preserve. | Requires settings |
| Risk of Error | Possible. | Minimal. |
| Time of adjustment | Minimum | Takes up time. |
Configure notifications and functions after connection
After successful pairing, Mi Band 4 requires fine-tuning. By default, many features may be disabled or not work correctly. First, check the Profile -> Mi Band 4 section of the app.
You need to re-activate the notifications from the right messengers (Telegram, WhatsApp, Viber) without this setting, the bracelet will vibrate when you call, but the text will not come, and it is also worth checking the permission to work in the background.
Pay special attention to adjusting the wrist lift to turn on the screen. After reset, the sensitivity may be lost. Calibrate this setting so that the screen lights up exactly when you look at the watch, saving battery power.
- 📳 Check to turn on vibration for all types of events.
- 🌙 Set up the “Do Not Disturb” mode and sleep time.
- ❤️ Activate continuous pulse monitoring if it has been disabled.
⚠️ Attention: For stable notifications on Android, be sure to add the Mi Fit application to the list of power saving exceptions (“Sunset” or “Work in the background”), otherwise the system will “kill” the synchronization process.
Frequently encountered errors and methods of their elimination
Even if all instructions are followed, there can be specific errors, one of the most common being “Device is busy” or “Pairing failed,” which means that the Bluetooth module on the wristband is busy processing a request from another device or is frozen.
In this case, put the bracelet on charge for 5-10 minutes, then remove and try again. If the error repeats, try connecting to the bracelet from another smartphone, untie it there, and then connect to the main phone.
Another problem is time desynchronization, so if you're on the wrong time when you're connected, don't panic. Go to the app, pull down the list of devices for forced synchronization. The time has to update automatically.
💡
The main secret to stable operation of the Mi Band 4 is the allowed background processes for the Mi Fit application. Without this, the bracelet will constantly lose touch.
If none of these methods work, the problem may be with the Bluetooth hardware after the power is reset, but this is extremely rare, and most of the time, it helps to completely remove the device from your Xiaomi account (via a web interface or app) and re-register.
