Modern wearables like the Xiaomi Mi Band 4 have become an integral part of the lives of millions of users, tracking every step and heartbeat. However, like any complex electronics, these devices can sometimes encounter software failures, freezes or smartphone connectivity issues. In such situations, standard reboot methods do not always help, and the only effective solution is a complete reset to factory settings.
This procedure returns the tracker to its original state by removing all the accumulated data about training and settings, but often this is what allows you to reanimate the device. Before you start, it is important to understand that resetting is a radical method that should be used when other methods have failed. In this article, we will discuss in detail all the available methods, from software through the application to hardware manipulation of contacts.
Mi Band 4 owners should know that the operating system of the bracelet, although simple, tends to accumulate errors during long-term operation. Resetting Xiaomi Mi Band 4 does not delete data from the Mi Fit or Zepp Life cloud if the account was linked, but local data on the device itself will be lost.
In the process of restoring the functionality of the gadget, we will consider not only the standard paths through the menu of the smartphone, but also the nuances of working with the Bluetooth module. Often the problem lies not in the tracker itself, but in the conflict of connection profiles. Understanding the architecture of the smartphone-bracelet bundle will help you avoid errors and keep the device in working order for many years.
Reasons to Reset Mi Band 4 Settings
There are a number of typical scenarios where the user has to resort to the procedure of cleaning the memory and settings of the tracker, most often due to software conflicts that occur after updating the firmware or prolonged operation without restarting, the device may stop responding to touch or display notifications incorrectly.
One of the most common problems is breaking the Bluetooth connection. The smartphone can see the device but refuse to pair, giving an authorization error, in which case the reset helps clear the cache of connections on the side of the bracelet itself.
- 🔌 Charging problems: The bracelet does not respond to the connection to the docking station or shows an incorrect percentage of charge.
- 📉 Overcharged battery: The device discharges in a few hours instead of the required 10-15 days.
- 🔄 Synchronization errors: Step and pulse data is not transmitted to the Mi Fit or Zepp Life app.
Another reason could be to sell the device or transfer it to another user, in which case a factory reset is a must to protect your personal information, and although the tracker stores a minimum of personal data, it is better to protect yourself and delete your activity history.
⚠️ Warning: If your bracelet is warranty-free and you plan to carry it to a service center, first try simply untie the device in the app.A full reset may hide some software errors that would help engineers diagnose the problem.
Also worth mentioning are cases where a user changes the main smartphone.When switching from Android to iOS or vice versa, sometimes there are profile conflicts that are resolved only by a complete cleanup of the Xiaomi Mi Band 4. This is especially true if you use the same Mi Account for different operating systems.
In some rare cases, a reset is necessary after a failed attempt to install custom dials. Unsupported file formats can lead to a "bootloop" (cyclical reboot) of the tracker interface, where hardware reset is often the only way out.
Preparation for the discharge procedure: what you need to know
Before you take any action, you need to do a number of preparatory steps to avoid losing important data about your physical activity and health, first of all, make sure that the companion app on your smartphone is working correctly.
Open the Zepp Life app (formerly Mi Fit) and force data sync. Pull down the app's main screen or press the update button to make sure all steps, sleep and pulse are uploaded to the Xiaomi Cloud server.
☑️ Checklist before resetting Mi Band 4
It is also important to check the charge level of the tracker itself. If the battery runs out during reset or flashing, the device can go into recovery mode, which is difficult to enter without special equipment. Charge the Mi Band 4 to at least 30-40%.
Another important thing is to turn off Find Device or search for the bracelet in the Bluetooth settings of the smartphone itself, and if the phone is constantly trying to reconnect in the background, it can interrupt the reset process.
- 📱 Update the app: Make sure you have the latest version of Zepp Life or Mi Fit installed from the official store.
- 🔋 Charging: Connect the tracker to the charger on 10-15 minutes before the start of the procedure.
- 📶 Stable Internet: Re-authorization after reset will require an active Internet connection.
If you have used third-party apps to download dials (like Notify for Mi Band), close them completely. background processes can interfere with correct execution of reset commands by sending your signals to the device.
Method 1: Reset via Zepp Life (Mi Fit)
The most secure and recommended method by the manufacturer is to use official software, which ensures that all commands are executed correctly and that the device remains tied to your account (unless you decide to unplug it).
To start, open the app on your smartphone and go to the device profile. This is usually the Profile tab below, then the My Devices section. Select your Xiaomi Mi Band 4 from the list of connected gadgets.
💡
If the Untie button is inactive, try restarting your smartphone and enabling geolocation (GPS), as Android requires this to work with Bluetooth devices.
In the bracelet management menu, scroll down to the bottom of the options list, and you'll find the Unbind button, which triggers the disconnection process, and the system will alert you that the data will be deleted from the device but will remain in the cloud.
Once confirmed, the bracelet vibrates and returns to pairing mode as if it had just come out of the box. QR-Mi code or logo waiting to be connected. That's the factory reset state.
If your goal is simply to reconnect the device to the same phone, you will need to re-search the devices in the app, and if you want to reset the settings for sale, at this point the process can be considered complete, since all user data is deleted.
It is important to note that some firmware versions may require input. PIN-It's a security measure that prevents data theft when you lose your device, and without the code, you can't reset your application.
Method 2: Hardware reset and reboot
In situations where software methods are not available (bracelet freezes, application does not see the device), you can try hardware methods. It is worth noting that the classic button "Reset" or a hole for the clip on the Xiaomi Mi Band 4 is not provided.
However, there is a method of "soft" hardware reset via charging. Connect the tracker to the charger (USB-dock). While charging, press and hold the touch button on the bracelet for 10-15 seconds.
- 🔌 Connection: Install the tracker in the charging dock connected to the power source.
- ⏱️ Holding: Keep your finger on the sensor until the Mi logo appears.
- 🔄 Reboot: The device must vibrate and reboot, which often eliminates minor failures.
This method isn't a complete factory reset in the strict sense of the word, but it clears RAM and restarts system processes, often enough to revive a frozen interface.
There is also a myth of “double tapping” or special touch combinations that supposedly reset settings, which Xiaomi’s official documentation does not describe.
⚠️ Warning: Do not attempt to disassemble the bracelet capsule or close contacts on the board yourself, this is guaranteed to lead to loss of warranty and possible failure of the device without the possibility of recovery.
If the bracelet is completely dead and does not respond to charging or touching, try leaving it on charge for a few hours. Deep discharge of the lithium-polymer battery is a common cause of death of the gadget, and it needs time to set minimum voltage.
Method 3: Use of third-party software (Notify for Mi Band)
For advanced users who don’t have much standard functionality, there is a powerful app Notify for Mi Band (formerly Tools & Mi Bandage) that allows you to manage the settings of the tracker at a level not available in the official application.
After you install and pair the Xiaomi Mi Band 4 with this app, go to Devices. Here you can find the option "Reset bracelet settings" or "Factory Reset." This action forcibly clears the device's memory.
The dangers of third-party applications
The advantage of this method is that it works even when the official Zepp Life app is glitching or can't perform the uncoupling.The app sends a direct command to clear the tracker's memory.
In addition, you can back up your settings before reset, and you can save the configuration of notifications, alarms, and activity targets to quickly restore them after the procedure.
Users note that after resetting via Notify, the bracelet sometimes works more stable, as system logs of errors that may have accumulated for a long time are deleted.
Elimination: If the reset did not help
There are times when even a complete reset doesn't solve the problem, which can indicate deeper hardware malfunctions or specific software bugs, and the table below shows common symptoms and possible solutions.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The bracelet is off. | Deep discharge or battery death | Leave on charging for 2-3 hours, check contacts |
| Can't see Bluetooth. | Communication module failure | Full reset via app + phone reboot |
| Sensor's not responding. | Floating or moisture | Drying (rice, silica gel) + hardware reboot |
| Quick discharge. | Background processes or wear | Disabling unnecessary notifications, resetting settings |
If after all the manipulations Mi Band 4 continues to behave incorrectly, it may be a physical malfunction.
It's also worth checking firmware compatibility. Sometimes, after a smartphone update (like a new Android version), the old firmware versions of the bracelet stop working properly. Check for updates in the app.
As a last resort, if the device is under warranty, contact an authorized service center.A check and packaging will significantly speed up the process of replacement or repair.
Set up Mi Band 4 after resetting
After successfully performing the reset procedure to the factory settings, the device returns to the "out of the box" state. QR-pairing.
Open the Zepp Life app and click Add Device. Select Mi Band 4 and follow the instructions on the screen. It's important not to try to add the device through the standard Bluetooth menu of Android/iOS settings, which will lead to an error.
During the setup process, you will be prompted to update the firmware. Software updates are a critical step after the reset, as they fix known bugs and improve stability.
- 🚶 Calibration: Walk 50-100 steps to recalibrate the accelerometer to fit your gait.
- ⌚ Dial: Set a new dial, as the standard dial will return after reset.
- 🔔 Notifications: Reconfigure the list of apps that should be notified at the wrist.
Remember to set your goals by step and alarm clocks. After resetting, all personalized settings return to default values set by the manufacturer.
⚠️ Attention: When you first sync after a reset, the process may take longer than usual.Do not interrupt the connection and hold the bracelet next to your smartphone until you complete the profile download.
Now your Xiaomi Mi Band 4 is ready to go live again, and a regular reboot (once a month) will help you avoid having to reset completely in the future.
💡
Regular data synchronization and periodic reboot of the bracelet (every 2-3 weeks) reduce the likelihood of critical errors requiring a complete reset.
