Xiaomi’s Mi Band smart bracelets have proven to be reliable and durable, but even the most stable electronics sometimes require a reboot. Xiaomi Band 4 users may find themselves in situations where the gadget stops responding to touch, loses touch with the smartphone or displays incorrect heart rate and steps. In such cases, a standard screen shutdown may not be enough, and the only right solution is a complete reset to factory settings.
The process of restoring tracker performance does not require special technical knowledge or expensive equipment. Resetting allows you to eliminate software errors, clear the cache of the system and return the device to its original state, ready for new synchronization. It is important to understand the difference between a simple reboot and a full formatting of memory, since these actions have different consequences for stored data.
In this article, we will take a look at all the available methods for recovering the Mi Band 4, from regular in-app funds to enforcement measures for “locked” devices. You will learn how to safely delete all personal data before selling a gadget or how to resuscitate a bracelet after a failed firmware update.
When you need a complete reset of the tracker settings
Not every minor malfunction requires drastic measures, but there are a number of symptoms that can lead to complete inoperability of the fitness bracelet. Most often, users resort to resetting when the device begins to behave unpredictably: the screen goes out and does not light up when raising their hands, notifications stop coming, or the bracelet endlessly tries to connect to the smartphone, consuming battery power.
Another critical reason is to sell or transfer the device to another person: Xiaomi Band 4 stores unique identifiers and data about the last synchronization. If you do not clean, the new owner may face binding errors, as the device will “remember” the previous owner.
⚠️ Warning: Before performing the reset, make sure that the battery charge is at least 20-30%. Interrupting the formatting process due to discharge can damage firmware, and it will be extremely difficult to restore the bracelet.
Reset is also required when changing your account in a companion app. If you used Mi Fit before and now switch to Zepp Life or Mi Fitness, the old binding may conflict with the new one, in which case cleaning the tracker memory is a must for the device to be successfully re-registered.
Preparation of the device and smartphone for the procedure
Before you start active, you need to properly prepare the bundle "smartphone-bracelet". chaotic pressing and attempts to reset without prior preparation often lead to the fact that the device goes into deep sleep and stops responding to commands. The first step should always be to check the level of charge, since the reset process requires stable power.
The second important step is to work with the app on the phone, so you don't have to try to reset the settings right away from the menu of the bracelet itself if it's still reacting, but you better break the software communication in the app first, and that will prevent the wrong configurations from automatically re-synchronizing immediately after you restart.
☑️ Checklist before reset
If the bracelet is still displaying the menu, it is recommended to manually check the firmware version. Sometimes the problem is solved not by reset, but by updating. However, if you are firmly determined to clear the memory, make sure that there are no sources of strong electromagnetic interference that can theoretically interfere with the communication process during the final stage of the connection break.
Method 1: Reset via Zepp Life or Mi Fit
The safest and most recommended method is to use official software, which ensures that all service files are deleted correctly and the device goes into the waiting mode for the new pair. First, open the Zepp Life app (formerly Mi Fit) on your smartphone and go to the device profile.
The control menu of the bracelet must find the item responsible for disabling. The interface may vary slightly depending on the version of the application, but the logic remains the same. Once confirmed, the bracelet vibrates and returns to the welcome screen with the Mi logo, which signals a successful completion of the procedure.
Importantly, this method not only breaks the connection, but also initiates a command to clear the pairing cache inside the tracker itself. This is especially important if you plan to use the bracelet with another phone.
⚠️ Note: After resetting through the application, all data that is not synced to the cloud will be lost. Make sure that your statistics for the last days are stored in your account profile before performing these actions.
If the "Disable" item in the app menu is inactive or hidden, try first removing the device from the "My Devices" list and then searching again. Sometimes the system requires re-confirmation of the deletion to avoid accidentally disabling the active tracker.
Method 2: Forced reset via bracelet menu
In situations where the app doesn’t see the device or freezes, you can try resetting directly through the Xiaomi Band 4 interface. Although there is no full “Factory Reset” menu in the user interface, there is a combination of actions that simulate this process.
This requires you to go to the bracelet settings, scroll to System or About (depending on the firmware version) and find the option to break the connection. In some versions, this may be hidden in deep submenu, but most users are referring to this method as forced reboot, which often solves problems without completely deleting data.
To perform a hard reset, which is often equated with resetting the settings by effect:
- 🔄 Go to the bracelet menu and find the "System" or "More" option).
- 🔌 Select the Unbind option if it is available in your region and software version.
- ⚡ If the menu is not available, put the bracelet on charging – this often causes a software reset of suspended processes.
It's worth noting that forced reset via menu is not available on all firmware versions of the global region. Chinese versions of the Mi Band 4 can have an extended developer menu where the reset option is made separately. If you have a global version, this method can only be limited to disconnection.

Method 3: Battery discharge method (Deep Reset)
When the software is powerless and the bracelet is dead, the time-tested "old-fashion" method is left, full discharge. It's the only way to perform a hardware reset without using a computer and special clips that can damage the body. The essence of the method is to bring the device to a state where there is not enough energy even to maintain errors in RAM.
Leave the bracelet on until the screen is completely turned off and the device ceases to respond to touch, then put it in storage for 2-3 days, this is necessary so that the chemical processes in the battery stabilize, and the residual charge is completely exhausted, only then you can start charging.
Put the bracelet on the charger. When the power is connected, the power controller initiates a system check. Once it detects a critically low charge level and no vapor configuration (due to discharge), the system can automatically start the recovery process or simply restart in its clean state.
| Parameter | Meaning/Action | Note |
|---|---|---|
| Model | Xiaomi Mi Band 4 | Relevant for all audits |
| Time of discharge | Until full shutdown + 48 hours | Warranty of RAM cleaning |
| Type of charging | The original dock connector | Use USB 2.0 to use it. |
| Indicator | Blink or logo | Signal of a successful start |
This method is safe for electronics, but it takes time. Don't try to speed up the process by putting the device in the cold or heating it - it can damage the lithium polymer battery. Patience here is a key success factor.
💡
Full battery discharge is the only safe way to perform a hardware reset without the risk of damaging the contacts or body of the device by mechanical action.
Fixing problems after resetting settings
Once the recovery procedure is successfully completed, the bracelet must go into pairing mode. The screen will light up and appear on it. QR-If it doesn't happen, and you see the old data interface again, it's not completely reset.
In some cases, there is a situation where the bracelet is turned on but not detected by the phone, which may be due to the fact that the smartphone “remembers” the old connection and tries to connect to it automatically, blocking a new search, you need to go to the Bluetooth settings of the phone, find in the list of Mi Band 4 and select “Forget device” or “Cancel pairing”.
If the bracelet is cyclically restarted (bootloop), showing the logo and turning off again, this may indicate damage to the firmware files. In this case, a simple reset will not help - you will need to flash the device through special utilities such as mi-band-firmware-gfx or similar tools for PC, which requires certain technical skills.
⚠️ Warning: If the bracelet heats up in the sensor or battery area after resetting and re-charging, immediately disconnect it from charging.This may indicate a short circuit inside the capsule or a battery malfunction.
Often users forget to update the app after resetting the bracelet. The old Mi Fit or Zepp Life version may not properly handle requests from a clean device. Make sure the latest available version of the software is installed in the app store (Google Play or App Store).
