How to Reset Xiaomi Band 4 to Factory Settings: The Complete Guide

Wearing the Xiaomi Mi Band 4 smart fitness bracelet gives you a sense of control over health, but sometimes the device begins to behave unpredictable: the screen goes out, steps are not synchronized, and notifications come with a delay of several hours.

Resetting a fitness bracelet to factory settings is a radical but effective method of solving most software problems: it deletes temporary files, clears the system cache, and breaks old, possibly damaged connections to a smartphone, and it is important to understand that this process will affect not only the software part, but also the activity history stored in the device's memory.

Before any manipulations begin, you need to understand the consequences: all unsaved statistics will be lost forever. However, the data that has already been synchronized with the cloud storage of the Mi Fit application (now Zepp Life) will remain safe. Below we will discuss in detail all the stages of preparing and executing the reset.

Preparation for the data-dumping procedure

Before you start taking action, you need to do a series of preparatory steps that will secure your data and ensure the success of the procedure. Synchronization is the first and most important step that you can not ignore. Open the application on your smartphone and force the data to update by pulling the screen down or pressing the appropriate button.

Make sure the battery is at least 50%. Although the reset process consumes minimal energy, interruption due to discharge can cause the firmware to malfunction. Also check the stability of the Bluetooth connection, as some commands are sent directly from the phone.

If you plan to sell the device or transfer it to another person, a reset is a must, ensuring that the new owner does not have access to your personal information, including heart rate, sleep and walking itineraries.

⚠️ Warning: After resetting all alarm settings, sedentary reminders and step targets will be removed. You will have to reset them manually or wait for the standard profiles to sync.

Breaking the communication through the Mi Fit app

The main method of controlling the tracker is through a mobile application. To start the detachment process, you need to log into the Zepp Life interface (formerly known as Mi Fit). Go to the Profile tab in the bottom menu, where the list of connected gadgets is displayed.

Find your Mi Band 4 in the list and click on it to enter the control menu. Scroll down to the bottom of the page where the optional options are usually located. There you will see "Sever Communication" or "Unbind." Pressing this button initiates the disconnection process.

The system will request confirmation of action, warning that the data will be deleted from the tracker, agreeing to send a command to clean the internal memory of the bracelet, and then the device will go to pairing standby mode, ready for new pairing.

• 📱 Open the application and go to the device profile.
• 🔗 Click on the disconnect button at the bottom of the screen.
• ✅ Confirm the deletion of data in the pop-up window.
• 🔄 Wait for the vibration and appearance of the logo on the bracelet screen.

It is important to note that a simple disconnect does not always mean a full Hard Reset. In some cases, a tracker can save some user data in hidden memory sections. To ensure cleanup, it is recommended to perform additional checks through the menu of the device itself, if this is available in the current version of the firmware.

💡

If the bracelet continues to display old data after the connection break, try to remove the Mi Fit app completely and install it again before pairing again.

Alternative methods of system reboot

Sometimes the software failure is so deep that standard methods through the application do not work, and in such cases, a physical reboot comes to the rescue. Although there is no physical button in the Xiaomi Band 4, there is a combination of actions that allows you to force the system to restart.

The first way is to set the tracker up to charge. Connecting to the power source often initiates a system start, especially if the device was in deep sleep or got stuck. Leave the bracelet on charge for 10-15 minutes, then check its reaction.

The second method is more radical and requires a full battery drain: leave the device on until it turns off on its own. Then put it on charge. When turned on, the system often conducts a self-check and clears temporary errors.

Using third-party bracelet management apps, such as Notify for Mi Band, can also offer deep reboot features.These tools have advanced access rights and can send specific commands to a device that is not available in the standard interface.

Elimination of synchronization errors after reset

Once you have done the reset, you may experience a situation where the phone doesn’t see the device or refuses to pair it, a common problem with caching old security keys in the smartphone operating system.

To solve the problem, go to your phone's Bluetooth settings, find the device list for "Mi Band 4" and select "Forget device" or "Cancel pairing" to delete the old connection profile.

Next, it is recommended to clear the cache of the Zepp Life app itself. In the Android settings, find the Apps section, select Mi Fit, and click Clear Cache and Clear Data. Fear not, this will not delete your activity history, since it is stored on the server.

• 🗑️ Remove the device from the Bluetooth list in your phone settings.
• 🧹 Clear the cache and data of the Mi Fit app in Android settings.
• 📡 Reboot your smartphone to update network services.
• 🔗 Search for new devices in the application again.

If these actions didn’t help, the problem may be the firmware version, the outdated bracelet software may conflict with new versions of the application, and the first time you connect after a reset, be sure to wait for the update.

⚠️ Warning: Do not move far from your phone or close the app during a firmware update. Breaking data can turn the bracelet into a brick».

Tracker setup after returning to factory settings

When the device is successfully reset and reconnected, it will appear as a blank slate, and this is the perfect time to rethink your activity goals and set up notifications only for really important applications.

In the app, go to your profile settings and set a realistic goal by step. Don't set records right away; start at a comfortable level and gradually increase the load. Also set Do Not Disturb mode by specifying your sleep hours so that the screen doesn't light up at night.

Pay attention to the wrist lift settings. If the screen lights up too often or doesn't respond to movement, calibrate the sensitivity in the device's menu, which will save battery life in everyday use.

For sports users, it is important to re-set the pulse zones, and while baseline values are calculated automatically, manual adjustments to your age and weight will make monitoring your workouts more accurate and useful.

💡

The correct initial setup after reset affects the device’s autonomy more than any other factor, so take 10-15 minutes to do so.
