Owners of fitness trackers Mi Band series often face situations where the device stops responding correctly to touch or synchronization with the smartphone. In such cases, standard control methods may not work, and the only way out is to force the system to restart the gadget. Understanding how to restart the Mi Band 4 is a key skill to keep your bracelet running smoothly.
The recovery process can range from a simple software reboot through an app to a complete hardware reset, and it is important to distinguish between these concepts, as improper actions can lead to loss of accumulated training data or the need to re-configure the device. In this article, we will discuss all available methods and nuances.
It is worth noting that Xiaomi did not provide a physical button on the body of the fourth generation trackers, which makes the control process a little more difficult than in classic electronics.
Staff reboot through the tracker menu
The safest and most recommended way to get the device back to normal is to use the built-in menu of the wristband itself, which does not cause data loss and simply updates the code to fix temporary operating system errors.
To perform the procedure, you need to unlock the tracker screen swipe up, then you should scroll through the menu to the end to the right or left (depending on the firmware version) until the icon with the image of the gear or the inscription More appears. In this section, you need to find the Reboot or System item, where the desired function is hidden.
After selecting Reboot, a warning will appear on the screen that the device will restart. Confirm the action by touching the appropriate area of the screen. The bracelet will go out for a few seconds, and then turn on again, showing the Mi Band logo.
⚠️ Warning: Don't try to reboot the device often unnecessarily.Frequent on and off cycles can speed up battery wear, although a single procedure is completely safe.
If the menu responds slowly but still works, this method is a priority: it allows you to clear the tracker's RAM from running background processes that could cause the interface to freeze.
Reset via the Mi Fit app
In cases where the touch screen of the bracelet reacts with a delay or does not respond at all, control can be taken over via a smartphone. the Mi Fit app (or Zepp Life) provides advanced capabilities for administration of connected devices.
Open the app on your smartphone and go to the Profile tab. From the list of My devices, select your Mi Band 4. Scroll down to the Settings or Additional section. Here you will find the Unlock or Disable button.
It's important to understand the difference between simply turning off Bluetooth and untying. Untying is a complete software reset that actually equates to rebooting the device configuration, and then the bracelet will return to a state ready for new binding, which often solves synchronization problems.
- 📱 Open the Zepp Life app on your smartphone.
- 🔗 Go to Profile and select the tracker.
- ⚙️ Find the Unleash button at the bottom of the menu.
- ✅ Confirm the action and wait for the resetting settings.
Once you do this, the tracker will reboot and reset the connection settings, and you will need to re-pair the connection, as you did when you first turned on the device, and this is guaranteed to eliminate software conflicts at the protocol level.
💡
Before you untithe, make sure that your activity data is synchronized with the server so that you do not lose the statistics of the steps taken for the current day.
Hardware discharge through charging
Sometimes software methods are powerless, especially if the tracker system is completely "hung" and does not respond to touch or Bluetooth commands, in which case the power-based method comes to the rescue.
The essence of the method is that connecting the Mi Band 4 to the charger initiates a hardware interruption of the controller, which often leads to an automatic reboot.
Remove the tracker capsule from the strap. Carefully insert it into the charger and plug it in. USB-cable to the power source (smartphone adapter or computer port) When connected, the capsule can vibrate or light up the screen.
| Action. | Expected reaction | The result |
|---|---|---|
| Connection to PC | Vibration, screen's not on. | Reboot possible |
| Connection to the adapter | Screen lights up, charge | High chance of resetting |
| Disconnection from charging | The screen goes out or shows the time. | System updated |
If the tracker doesn't come alive after you've connected to the charge, try holding the touch area (if it reacts even slightly) when the cable is connected. The combination of power and touch can trigger Hard Reset.

Removing interface freezes
One of the common problems Mi Band 4 owners have is sticking the interface when the animation stops, but the device is formally turned on, in which case a full reboot may not be necessary, softer methods are enough.
Try to force a change of face. In the app on your smartphone, choose a different design of the watch and apply it. Changing the graphical shell causes the system to redraw the screen, which often "props" the hanging process of drawing.
Also effective is to turn off all notifications for a short time: go to the notification settings in the app and uncheck all apps (WhatsApp, Telegram, calls) and this will reduce the load on the processor and can bring the interface back to life.
- 🔄 Change the dial to the built-in standard.
- 🔕 Disable all notifications in the app.
- 📉 Reduce the screen brightness to a minimum.
- 🚫 Turn off the function "Raising the wrist" in the settings.
If the bracelet reacts after these manipulations but is slow, it is recommended to update the firmware. New versions of the software often contain corrections for errors that cause such hanging.
⚠️ Warning: If the interface is stuck during the firmware update, do not disconnect the bracelet from charging or break the connection to the smartphone within the first 10 minutes.
☑️ Diagnosis of freeze
Firmware and software updates as a method of treatment
If the standard Mi Band 4 reboot doesn’t fix the bugs, the cause could be corrupting the operating system files, in which case the only solution is to reinstall the software.
The process of updating (or flashing) completely replaces system files with new, serviceable versions, a radical but very effective way to treat the tracker's software "diseases," and make sure that the bracelet is at least 20% charged before the procedure begins.
In Mi Fit or Zepp Life, go to your device profile. If an update is available, a notification will appear. Click Check for updates. If there is no update but there is a problem, you can try to find and install the newer version manually through third-party resources, but this requires caution.
During the upgrade process, the tracker will reboot itself several times, the screen can go out and light up, and the progress bar can freeze in place for a long time, which is normal for the system to write data to flash memory.
💡
Reinstalling the firmware is the most reliable way to fix software errors that are not fixed by a normal reboot or resetting settings.
