Modern wearable gadgets such as the Xiaomi Mi Band 4 are complex computer devices running a specialized operating system. Despite high reliability and optimization, software failures, interface freezes or data synchronization errors can occur during operation. Reboot is a universal tool for solving most of these problems, allowing you to clear RAM and restart system processes.
Unlike traditional electronic watches, activity trackers don’t always have a physical button to force the system to shut down or restart. This often puts users at a loss when the screen stops responding to touch or the device doesn’t connect to the smartphone. In this guide, we’ll take a look at all the existing ways to restore the health of your fitness bracelet, from standard methods to forced reset.
Understanding the right algorithms will help avoid unnecessary damage to the device and ensure its long-term functionality.We will consider not only standard procedures, but also the nuances of working with different versions of firmware and third-party software.
Staff reboot through tracker settings
The safest and most recommended way to restore the device to normal operation is to use the built-in menu. If the touch screen of your Mi Band 4 reacts to touch, but the system is not working correctly, you should consult software controls. This method does not lead to loss of accumulated data about training or settings, as it does not affect internal memory deeper than necessary for a cyclic restart.
To perform the operation, you need to unlock the bracelet screen and swipe left or right to find the Settings menu item (cog icon). Inside this section, you need to find the System option or immediately go to Reboot if it is displayed separately. The confirmation of action will start the process of turning off and then turning on the device, which usually takes about 10-15 seconds.
⚠️ Warning: During the reboot process, the screen may go out and light up several times. Do not try to charge the device or press other buttons at this time, so as not to interrupt the system processes.
Sometimes users are faced with a situation where there is a menu item, but the system does not respond to the choice, in which case it is worth trying to clear the interface cache, although MIUI for Wear does not explicitly have such a function, so only a full restart remains effective. If the standard method does not work, move to more radical measures.
- 🔄 Find the gear icon in the main menu of the bracelet.
- 📲 Go to the System or More section.
- ✅ Select Reboot and confirm the action.
⚠️ Warning: Make sure the battery level is at least 10% before the procedure starts so that the device does not turn off at a critical moment.
Reboot with Mi Fit (Zepp Life)
Control of the tracker is primarily via a paired smartphone, and the Zepp Life app (formerly known as Mi Fit) provides advanced diagnostic capabilities. If the interface on the bracelet itself is locked or does not respond, a software reset via the phone is the optimal solution, which is especially effective for Bluetooth connection problems when the gadget "sees" the phone, but the data is not transmitted.
You need to open the app on your smartphone, go to the Profile tab and select your Xiaomi Mi Band 4 from the device list. The gadget management menu should scroll down to the bracelet settings section. There is a Break Communication or Unbind feature, which essentially initiates a software reset of sync settings and often leads to an automatic reboot of the tracker.
☑️ Checking before resetting through the application
Importantly, a disconnection may require re-pairing, but in most cases, after the Unbind command is executed, the tracker system will independently initiate a reboot cycle to apply the changes, which is the standard algorithm for the communication protocol between the mobile device and the wearable electronics.
- 📱 Open the Zepp Life app on your smartphone.
- 🔗 Go to the device profile and find the settings.
- 🚫 Click "Sever Communication" for Forced Restart of Modules.
⚠️ Warning: After the connection is broken, all unsynchronized training data that was not transmitted to the server may be lost.
Forced reboot and reset to factory settings
In situations where the device is completely frozen, the screen does not respond to touch, and standard methods do not help, enforcement measures are required. For the Mi Band 4, there is no button combination (as there are no buttons physically), so deep discharge or program reset via the menu is used. The cardinal solution is a full reset, which returns the device to its original state.
To perform a full reset via the menu (if the touchscreen works), go to Settings → System → Factory Reset. This operation will delete all user data, dial settings and unsaved workouts. Data recovery after such a reset is impossible, so this method should be resorted to only as a last resort when other methods are powerless.
What happens at Factory Reset?
If the screen doesn't work at all, you can try the "deep discharge" method. Leave the bracelet on until the battery runs out completely and the device shuts down itself. Then put it on charge. When turned on after charging, the system often starts in a "clean" state, which is equivalent to rebooting. However, this method is not recommended to be used often, since deep discharge is harmful to lithium polymer batteries.
- ⚙️ Use the Factory Reset menu to clean up your memory completely.
- 🔋 Or wait for a full discharge for a hardware shutdown.
- ⚡ Charge the device to 100% after spontaneous shutdown.
Full reset deletes all data without recovery, only use critical system errors.
Use of the third-party app Notify for Mi Band
For advanced users who feel that the official app is not enough, there is a powerful third-party solution – the Notify for Mi Band app. This tool allows you to access hidden tracker features, including advanced reboot management and diagnostics. The application is available on Google Play and requires the official Zepp Life or Mi Fitness installed for initial synchronization.
In the Notify for Mi Band interface, you need to go to Devices, select your Mi Band 4 and open the Action or Tools tab. There is an option called Reboot Device, which sends a special command to the tracker, forcibly restarting its operating system. This often helps when the standard Bluetooth stack on the smartphone is stuck and does not see the bracelet.
In addition, the app allows you to reboot individual modules, for example, only the pulse sensor or Bluetooth module, without affecting the entire system. This can be useful to save time if the problem is localized to a particular sensor.
- 📲 Download and install Notify for Mi Band app.
- 🔌 Perform pairing through the main Xiaomi app.
- ⚙️ In the "Actions" section, select the device reboot command.
⚠️ Attention: Using third-party apps can lead to unstable notifications or increased battery consumption of the smartphone due to background activity.
Comparison of methods of recovery of the device
The choice of the specific recovery method depends on the nature of the problem that has arisen. It is not always necessary to completely reset, if a simple software reboot is enough. Below is a comparison table that will help determine the best way to proceed in your situation.
| Method | Data retention | Implementation time | Difficulty |
|---|---|---|---|
| Through the wristband menu | Complete. | 15-20 seconds | Low. |
| Through the Zepp Life app | Complete (data on the server) | 30-40 seconds | Low. |
| Notify for Mi Band | Complete. | 20-30 seconds | Medium |
| Factory Reset (Dumping) | No (all settings are removed) | 1-2 minutes | Tall. |
| Deep discharge. | Unknown (risk of loss) | A few days. | High (harm to the battery) |
And from the table, you can see that the first method is the most effective way to solve everyday small problems, it's fast and safe. Third-party software is justified if you're an active user of advanced notifications. Factory Reset remains the last resort.
💡
Regularly rebooting (once a week) through the wristband menu helps to keep sensors running smoothly and prevents temporary error files from accumulating.
Frequent problems after reboot and their solution
After a successful reboot, the user may encounter a number of typical situations that are not a breakdown, such as the bracelet may spend longer than usual searching for GPS satellites (if the model supports, although the MB4 does not have GPS, it uses a phone) or synchronizing time.
If the Russian language is lost or the font is lost after the reboot, you need to re-synchronize the device with the application. In the profile settings in Zepp Life, make sure that the correct language and region is selected. Sometimes you need to reload the dial, since the graphic elements cache may have cleared.
💡
The lack of step data immediately after turning on is normal, synchronization with the server can take up to 5-10 minutes of active use.
In rare cases, the device may enter debugging mode or freeze on the logo. If this happens, try connecting the bracelet to the charger. Often the power connection interrupts the boot cycle and allows the system to start correctly. If the persists problem may be damaged firmware and you need to flash through the engineering menu, which requires special skills.
- ⏱ Give me the device. 5-10 Minutes of primary synchronization.
- 🔄 Check the language settings in the app after restart.
- 🔋 Connect charging if the bracelet is stuck on the logo.
⚠️ Attention: If the bracelet warms immediately after rebooting and discharges quickly, there may be damage to the battery or power controller.
