How to Reset Xiaomi Mi Band 4 Bracelet: The Complete Guide

Owners of popular fitness trackers often face the need to return the device to its original state, which may be required when selling the gadget, transferring it to another user or when software errors occur that interfere with normal synchronization with the smartphone. Xiaomi Mi Band 4 is no exception, and the cleaning procedure requires careful attention to detail.

The reset process is not complicated, but it is very different from the usual electronics reboot. It is important to understand that simply disconnecting the tracker from the phone does not remove the accumulated statistics or break the secure connection completely.

In this guide, we will take a detailed look at all the steps in preparing and executing an operation, learn how to properly break communication between devices to avoid problems with re-association in the future, follow the instructions to help keep your personal data safe and provide a clean start for a new owner or system.

Preparation for performing resetting of settings

Before any manipulation of the tracker software, you need to make sure that the connection is stable. The Bluetooth module of the smartphone must work correctly, and the battery charge of the bracelet itself must be at least 20-30%. This is critical, since interrupting the data recording process can lead to a software failure.

If you plan to simply reconnect your device to the same account, a full reset may be redundant, but when you change ownership or switch to a new phone, a complete cleanup is a must to protect your sensitive information.

💡

Before resetting, make sure that all important training data is synchronized with the application server, as after cleaning, they will be lost irretrievably.

Make sure your smartphone has an up-to-date version of the Mi Fit app (or Zepp Life, as the services have been renamed) and older versions of the software may not display the device control menu correctly or may not have the necessary features to remotely control the wristband.

Unlocking the device through the Mi Fit application

The main and most correct way to return the tracker to the state of “out of the box” is to use the official mobile application, which ensures that all data is deleted not only from the memory of the gadget, but also from the cloud storage associated with your profile.

Open the app on your smartphone and go to the Profile tab. From the list of connected devices, select your Xiaomi Mi Band 4. The interface may vary slightly depending on the version of the operating system, but the logic remains the same for all users.

At the bottom of the screen, you'll find the device control button. Click on it to open the additional menu. Here we're interested in the Unbind option. The system will request confirmation of action, warning that all data will be deleted.

• 📱 Open the Zepp Life app (formerly Mi Fit) on your smartphone.
• 🔗 Go to Profile and select your bracelet image.
• 🗑️ Click the Untie button and confirm the deletion of data.
• ✅ Wait for vibrations and reports of successful completion of the procedure.

Once confirmed, the bracelet vibrates, and a reset animation may appear on its screen. From now on, the device is no longer associated with your account. If you plan to sell the gadget, at this stage the main mission is accomplished - the new owner will be able to link it to his phone.

Alternative method via Bluetooth settings

Sometimes there are situations where the application is unavailable, frozen or not working correctly, in which case you can try to remove the pairing directly through the settings of the smartphone operating system, this method is less reliable for completely cleaning the tracker data, but breaks the connection.

Go to your Android or iOS device settings and find the Bluetooth section. In the list of available and previously connected devices, find the Mi Band 4 entry. Click on the information icon (usually the letter "i" in a circle or gear) next to the name.

Select Forget the device or Unpair. This action will force the connection to be severed. However, it is important to understand that your activity data may remain in the memory of the bracelet until you attach it to a new phone and sync or completely reset through the application.

⚠️ Note: Deleting the device only through Bluetooth settings does not guarantee complete clearing of personal data from the tracker memory.

If you then try to reconnect the bracelet, it may require resetting through the app, a security mechanism that prevents unauthorized access to the previous owner's data, so the method through Bluetooth settings is better seen as a temporary solution or a first step before a complete cleanup.

Reset via the menu of the bracelet itself

In some cases, when communication with the smartphone is lost forever (the phone is lost or broken), the only option is to use the interface of the tracker itself. Xiaomi Mi Band 4 has a touch screen, which allows you to control some functions without the phone.

Swipe your finger across the bracelet screen left or right to find the Additional menu (three-dot icon or gear icon) and find System or More inside the menu. This is where the device's deep settings are hidden.

Find the Unbind option, which triggers the disconnection process from the last known smartphone, and then the bracelet goes into the connection standby mode, displaying the device. QR-code or suggestion to scan the code through the application.

It's worth noting that this method isn't always available on all firmware versions. Some software updates may hide this feature, leaving full control only over the mobile app. If you didn't find one, then your method is only through your smartphone.

What to do if the bracelet is not reset

There are times when standard procedures fail, the bracelet may freeze, not respond to commands, or give out a synchronization error, and this requires a deeper approach to solving the problem.

Try to reboot the tracker completely. Put it on the charger. When you connect to the power source, the device often makes a soft restart. If that doesn't work, you can try to empty the bracelet to zero, leaving it on for a few days, and then charge it to 100%.

Another effective method is to clear the app cache on your smartphone. Go to your phone's settings, find the Apps section, select Zepp Life, and click Clear Cache. Then try to do the unbundling procedure again.

If none of these methods worked, it may be a hardware malfunction or a deep file system corruption, and in rare cases, you need to flash the device through a special engineering utility, but this is a task for service centers.
