Fitness bracelet users often face the need to turn off the device completely, but the Xiaomi Mi Band 4 is more complicated than it seems at first glance. Unlike classic gadgets, there is no physical on and off button, and the software menu is limited to basic activity tracking functions. This is done to save battery power, but creates difficulties when you need a forced reboot or a complete reset of the system.
If your tracker is stuck, unresponsive to touch, or no longer synced with your smartphone, standard methods may not work. In this guide, we will look at all the available ways to force power out, programmatically reboot via the Mi Fit app (or Zepp Life) and radically reset to factory settings. Understanding these processes will help extend battery life and restore the device to service center.
It's important to distinguish between sleep mode, reboot and shutdown. In most cases, a simple reboot is enough to solve software problems, which doesn't delete your data, but cleans the system's RAM. Let's look at each method in detail, starting with the standard controls.
Staff disconnection through the device menu
The first and most obvious way to control the status of the tracker is to use the built-in interface on the tracker. OLED-However, owners of Xiaomi Mi Band 4 will be disappointed: the standard “Switch off” function in the menu simply does not exist. Engineers of the company decided that the user does not need to permanently turn off the device, since it consumes minimal amount of power in standby mode.
However, you can find an option in the bracelet settings that temporarily limits sensors: Go to the device menu, flip to Settings and select Screen and Brightness, and you can activate the Wrist Raising function or change the screen timeout, which indirectly affects power consumption, but does not turn off the tracker completely.
⚠️ Attention: Finding the function of full shutdown in the bracelet menu is a waste of time, since Xiaomi programmers did not put this option in the firmware of the Mi Band 4.
To control basic functions, such as turning on or off pulse tracking, you need to use swipes across the screen. For example, the Pulse card allows you to manually start a measurement or stop it, but the background operation of the sensor is only regulated through the app on the phone. This is an important nuance that beginners often miss.
💡
Built-in menu for a complete power out in Xiaomi Mi Band 4 is not provided by the manufacturer.
Forced reboot through the app
The most effective and safe method of “disconnecting” and then turning on is software rebooting through a conjugated application. For this procedure, you will need a smartphone with Mi Fit or Zepp Life installed. This method is recommended for small interface failures or data synchronization problems.
The process is this: open the app, go to the device profile, and find the Settings section. At the bottom of the options list, often the Break or Unplug button is hidden. Pressing this button initiates a Bluetooth connection reset and often causes the tracker to automatically reboot.
- 🔄 Open the Zepp Life app on your smartphone.
- 📱 Go to the Profile section and select your bracelet.
- ⚙️ Find the "Settings" item at the bottom of the screen.
- 🔻 Click "Tear off the pairing" or "Untie".
Once the connection is broken, the tracker will return to standby. To complete the reboot cycle, simply plug it into the charger. Charging is the only hardware way to wake the device after deep discharge or software lock. USB-The computer port or adapter instantly activates the system.
☑️ Software Reboot Algorithm
Method of complete battery discharge
If the software methods don’t help and the device is stuck, without reacting to touch or connection to charging, the only way, although not the fastest way, is to completely discharge the battery. This method is a “hardware reset” that is guaranteed to turn off any electronic gadget, including the Xiaomi Mi Band 4.
The idea is to leave the bracelet unattended until the battery reaches 0%, and once the power runs out, the device will turn off on its own, and then it can be charged and it will turn on in normal operation mode, because at start-up the system passes a file integrity check.
⚠️ Attention: Deep discharge of lithium polymer batteries is not recommended regularly, as this can reduce the overall battery life.
To speed up the discharge process, you can activate all the power-intensive functions, turn on constant pulse monitoring, notifications from all applications, vibration for each event and maximum screen brightness, and use of stopwatches and alarm clocks will also help, this will create maximum load on the processor and quickly deplete the charge.

Reset to factory settings (Factory Reset)
When you want to not just turn off the device, but completely clear it of user data and settings, a factory reset is performed, a procedure that is necessary before selling the bracelet, transferring it to another person, or critical firmware errors that are not eliminated by a normal reboot.
It’s important to understand that Factory Reset deletes all accumulated workout data, customized dials and account binding. Once reset, the Xiaomi Mi Band 4 will look like a new one just pulled out of the box.All data synced to the cloud will remain secure unless you delete the in-app account.
To perform discharge through the annex:
- 🗑️ Go to the bracelet settings in the Zepp Life app.
- 🔍 Find the option "Factory Reset" or "Reset settings".
- ✅ Confirm the action in the pop-up window.
- ⏳ Wait for the process to be completed and the reboot.
There is also a hidden way to reset via the bracelet menu itself, if available in your firmware version, which is usually in Settings -> System -> Reset. However, most often this feature is blocked and only available through an external application to prevent accidental deletion of data.
Table of comparison of disconnection methods
To make it easier for you to choose the right method, we have organized all the methods into a table that will help you quickly navigate the situation and choose the best algorithm for actions depending on your goal and the current state of the device.
| Method | Data retention | Implementation time | Recommended use |
|---|---|---|---|
| Interconnection break | Yes. | 1-2 minutes | Solving small glitches, changing the phone |
| Charging the device | Yes. | Instantly. | Getting out of deep sleep, turning on |
| Complete discharge. | No (data stored in memory) | 2-5 days | Critical freeze, button failure |
| Factory Reset | No (complete removal) | 3-5 minutes | Preparation for sale, serious software errors |
As you can see from the table, the safest and fastest method for everyday use is the break-up method, which allows you to refresh the system without losing the statistics of training, and the use of full discharge should be left to the last resort when other methods have exhausted themselves.
Disabling Notifications and Functions
Often, the question of “how to turn off” users do not mean turning off the power, but deactivating irritating functions such as constant vibrations, light signals or tracking specific parameters. Xiaomi Mi Band 4 allows you to flexibly adjust these parameters, turning a smart gadget into a simple chronometer.
To disable notifications from specific applications (WhatsApp, Telegram, Viber), go to the Application Notifications section in the application. Here you can uncheck unnecessary programs, which will not only eliminate unnecessary noise, but also significantly prolong battery life, as the screen will light up less often.
To turn off heart rate monitoring, which some users consider redundant:
- ❤️ Open the Zepp Life app.
- 📊 Go to the device profile.
- 🚫 Find the item "Pulse monitoring".
- 🔕 Select "Disabled" or increase the measurement interval.
You can also turn off vibration when you step or achieve goals, and this is done in the Settings -> Vibration section, and turning off all sound and tactile signals makes wearing the bracelet as invisible as possible, which is relevant for meetings or sleep.
💡
To maximize energy savings, turn off the "Raising the wrist" in the screen settings. This will prevent the display from accidentally turning on when active hand movements.
Solving problems with hanging (Dead Boot)
When the Xiaomi Mi Band 4 stops responding to any action, it's called a "Dead Boot," and the screen can burn black or show a static image, and 90 percent of the time it's a software failure, not a hardware failure, and the main task in this situation is to initiate a restart of the power controller.
The first thing you need to do is connect the bracelet to the original charger. Even if the screen does not light up, applying voltage to the contacts can kick the system. Leave the device on charge for 15-20 minutes. If nothing happens after that, try briefly turning off and plug in the charge every 5 seconds (pulsation method).
⚠️ Warning: Do not attempt to disassemble the bracelet or close the contacts yourself, this will result in loss of warranty and possible damage to the water protection.
If that doesn't work, it's still an app-based method of "reviving" the device, sometimes a re-interfacing attempt in Mi Fit causes the device to go out of sleep, and in rare cases, placing the bracelet near a strong electromagnetic field source (such as a running microwave or a powerful speaker) helps, but this method is risky and not guaranteed.
