Owners of Xiaomi fitness trackers periodically face situations when the device stops responding correctly to commands or completely refuses to turn on. If your Xiaomi Mi Band 4 freezes, does not sync with your smartphone or shows incorrect pulse data, the only right solution is a forced restart. Unlike smartphones, there is no physical power button, which often puts users in a stupor.
The recovery process does not require specialized hardware or deep knowledge of electronics, but it is important to understand the difference between a normal reboot and a full factory reset. In the first case, we simply update the tracker software, in the second, we delete all the accumulated data and settings, returning the device to the “out of the box” state.
In this guide, we will discuss in detail all available methods for resuscitating your tracker. You will learn how to use the regular functions of the Mi Fit (or Zepp Life) application, how to perform a hard reset through a hidden menu and what to do if the screen of the gadget is turned off and does not respond to touch.
Differences between a reset from a complete data reset
Before you start active, you need to be clear about what operation you are going to perform. A normal reboot is a routine procedure, similar to turning off and on a computer. It cleans RAM, completes the hanging processes and updates connections to the Bluetooth module of the smartphone, while your steps, sleep and pulse data are stored in the tracker memory and synchronized with the phone after turning on.
It's a completely different matter, Factory Reset, which is designed to solve problems or prepare the device for sale to a new owner, and when you reset the tracker, you delete all user settings: activity targets, the dial you select, notification settings, and screen unlocking. It's important to note that the activity history already transmitted to the Mi Cloud or Zepp servers will not suffer, but local data on the wristband will be destroyed.
⚠️ Warning: Before performing a full reset, make sure your activity data is successfully synchronized with the smartphone app. If the bracelet does not connect to the phone, the reset attempt may result in irretrievable loss of data accumulated since the last synchronization.
The choice of method depends on the current situation. If the tracker is just "glutching" or shows the wrong time, rebooting is enough. If you forget the password to unlock the screen (if it was installed) or the device constantly produces pairing errors, you will need a complete reset. Understanding this difference will help you choose the right strategy for restoring the functionality of the gadget.
💡
Always try to perform a normal reboot through the app first. Use a full reset only in extreme cases when other methods have not worked.
Reboot method through the application Mi Fit (Zepp Life)
The safest and most recommended way to bring the Xiaomi Mi Band 4 back to life is to use the official mobile app. formerly known as Mi Fit, now often called Zepp Life, but the functionality for working with trackers has remained the same, which allows you to perform a software reboot without risking damage to system files.
To start, make sure your smartphone is in close proximity to the bracelet and the Bluetooth module is active. Open the app and go to the Profile tab. From the list of connected devices, select your Mi Band 4. If the device appears as "off," try pulling the screen down to update the list or rebooting Bluetooth on the phone.
Once you log in to the device menu, scroll down to the bracelet settings or the System section. The interface may vary slightly depending on the firmware version, but the logic remains the same. You need to find Reboot. Pressing this button initiates a command to be sent to the tracker, after which the animation of the Mi logo will appear on the bracelet screen, indicating the beginning of the process.
- 🔄 Standard Reboot: Select the Reboot option from the bracelet menu to update the system.
- 📱 Device Uncoupling: If rebooting doesn’t help, try selecting Unbind, which will also reset your connection settings.
- 🔋 Charge control: Before any operations, make sure that the battery is at least 20% so that the device does not turn off at a critical moment.
If the reboot option is missing or inactive in the app menu, it could indicate problems with Bluetooth drivers or the app’s firmware itself, in which case try updating the app through the Google Play store or App Store, and check if you need to update the firmware of the bracelet itself, which often fixes stability errors.
☑️ Checklist before resetting via app
Using the tracker's own menu to reset
Some versions of Xiaomi Mi Band 4 firmware include the ability to reset directly through the wearable device interface. This is especially convenient if the smartphone is lost, the application is not working correctly or the phone is temporarily unavailable. However, it is worth remembering that navigation through the tracker menu with a touch screen can be less accurate than finger control on a smartphone.
To find this feature, unlock the bracelet screen (if you have a pin code installed) and scroll left or right until you find the Settings item (the gear icon). Inside this section, you should look for the System or About subsection. This is where key device settings are hidden, including the software version and the reset button.
| Item | Action. | The result |
|---|---|---|
| Settings | Entrance to the configuration menu | Access to system options |
| System / About the system | Selection of the information section | Displaying the software version |
| Reset (Reset) | Confirmation of action | Complete data reset |
| Unbind (Unbind) | Breaking the phone connection | Resetting Bluetooth settings |
When you select Reset or Unbind, you will see a warning on the screen that all data will be deleted, click the touch button or hold your finger on the screen for a few seconds until the vibration passes, and then the tracker will reboot and return to factory settings.
⚠️ Attention: If the tracker screen does not respond to touch or the menu does not open due to freezing, software reset through the device interface will not be possible.
What if the menu on the bracelet is not readable?
Forced reboot through the charger
The situation where Xiaomi Mi Band 4 is completely frozen and does not respond to touch or commands from the smartphone is the most common. In this case, the only way out is to use the hardware method of rebooting. Since the device does not have a physical button, the role of the trigger for the system is the connection to the power source.
To perform this procedure, you will need an original charger or quality analogue, as well as a power source (USB-Computer port, power bank or network adapter: It is important that the charging cable is in good working order, as poor contact may not trigger the wake-up process of the power controller.
Place the tracker in the charging dock and connect it to the network. If the device was completely "dead", on the screen may not happen during the first few days. 10-15 It's normal -- it takes time for the system to check the voltage and initialize the loader, and once the power controller has fixed a steady current, the system will force the system to restart.
- ⏳ Long-term charging: if the battery has gone into deep discharge, leave the device on charge 30-60 minutes, even if the screen does not immediately light up.
Once the Mi logo or charging indicator appears on the screen, the device can be turned off. In most cases, after this procedure, the tracker starts to work normally. If after connecting to charging, the screen lights up but goes out again after a few seconds, perhaps the problem lies in critical battery wear or software failure that requires flashing.
💡
Connecting to a charger is a versatile way to “wake up” the power controller and initiate a hardware reset when software methods are powerless.
Solving Connection Problems After Reset
After successfully resetting (regardless of method), the Xiaomi Mi Band 4 returns to a state ready for initial pairing. However, users often find that the smartphone “does not see” the tracker or refuses to connect to it, giving authorization errors, this is due to the fact that old device records in the phone’s Bluetooth memory can conflict with the new bracelet state.
The first step should always be to remove the old device profile from your smartphone’s Bluetooth settings. Go to Settings → Bluetooth, search the Mi Band 4 list and click “Forget the device” or “Unpair the pairing.” Only after this cleaning can you start looking for new devices in the Zepp Life app.
If the search does not give results, make sure that the tracker is displayed. QR-The newer versions of the firmware require a code scan or a bracelet screen confirmation for security, and check if the antivirus or phone energy saving system is blocking the application in the background.
⚠️ Note: Do not try to connect the bracelet directly through the standard Bluetooth menu settings Android or iOS without using the application. For full operation Mi Band 4 requires mandatory authorization through the account Mi Account in the intermediary app.
In rare cases, you need to completely reinstall the app. Delete Zepp Life, restart your smartphone, download the latest version from the official store and log in to your account. After that, the search and binding process should be successful. If the error persists, try to tie the bracelet to another smartphone to prevent the malfunction of the tracker itself.
