Owners of popular wearable gadgets often face a situation where standard electronics control methods stop working as smartphone users are used to. The question of how to turn off the Xiaomi Band 4 arises for beginners regularly, since the physical button on the device’s body is completely absent. This design decision is dictated by the need to ensure maximum moisture protection and minimize the size of a compact tracker, making the usual (long press) to turn off impossible.
Many users mistakenly believe that the device is malfunctioning if it does not respond to prolonged pressing on the touch area. In fact, the architecture of this bracelet is built on the principle of constant waiting for commands, and a complete power outage is required only in rare cases. Understanding the logic of the Mi Band 4 will help avoid unnecessary stress and improper actions with the device.
In this article, we will discuss in detail all available ways to control the state of the device, including software methods and physical effects. You will learn why the developers abandoned the classic switch and how to properly maintain the gadget.
Why there is no classic shutdown button
The Xiaomi Mi Band 4 design features a monolithic capsule body that is completely sealed. The absence of mechanical buttons on the side faces or screen is a conscious engineering move aimed at raising the waterproof class to the 5 ATM standard. This allows users to swim in the pool without fear of moisture getting inside through the keyholes.
The device is controlled exclusively through a capacitive sensor located at the bottom of the display. The bracelet software does not contain the "Switch off" item in the main menu, since the device is focused on round-the-clock monitoring of health indicators. Full battery discharge is the only regular way to completely shut down, unless you use special engineering methods.
⚠️ Warning: Attempts to disassemble the case or find hidden contacts to physically shut down the battery will result in loss of warranty and possible damage to moisture membranes.
It is worth noting that low energy consumption OLED-The screen and optimized processor allow the device to work for up to 20 days without recharging, which is why the need for frequent shutdowns is eliminated, and the deep sleep mode is activated automatically when there is no activity.
Software reboot via Mi Fit app
The safest and most recommended way to manage the status of the tracker is to use official software. To interact with the bracelet, you need to install the Mi Fit application (or its current analogue Zepp) on your smartphone. Communication between devices is carried out via Bluetooth Low Energy protocol, which provides stable data exchange.
To reset or reboot the system, you need to open the application and go to the device profile. The bracelet settings menu often hides features that are not available on the screen itself. However, it is worth considering that there may not be a direct command to turn off, but there is a function to unload or reboot that initiates a software restart.
The reconnection process eliminates software errors, interface freezes, or step synchronization problems, similar to rebooting a computer, where you have to shut down all the background processes and start the system again.
☑️ Algorithm of rebooting through the application
After the command is executed, an animation of the Mi logo will appear on the bracelet screen, indicating a successful reboot. If the device does not respond, try turning off Bluetooth on the smartphone and turning it on again to force the connection to rewire.
Method of complete battery discharge
If software methods fail or you need to preserve the device for long-term storage, the only regular way to completely shut down is the battery discharge. The lithium polymer battery installed in the Mi Band 4 has a small capacity, but the power controller protects it from a deep discharge below the critical level.
To implement this method, you need to leave the bracelet on with an active screen or in the continuous network search mode if it is not paired, the power consumption in this mode is maximum, and the device will go to full zero in a few days, after which the system will automatically shut down.
Chemical processes inside the battery can lead to capacitance degradation if the voltage falls below a certain threshold for more than a few months.
How do you speed up the discharge?
When the charge indicator shows 0% and the device goes out, it will go into storage mode. To re-energize, you will need to connect it to the charger, since spontaneous activation is impossible.
Use of charger for activation
Once the bracelet has been completely turned off (discharged or reloaded), it requires external influence to turn it on. Contact pads located on the inside of the capsule are not only used to charge, but also to signal the wake of the controller.
The process of turning on is as simple as possible: just install the capsule in the charging dock and connect it to a USB power source. The screen will light up almost instantly, showing the brand logo and current charge level. This is the only way to wake up the device after a deep sleep.
| Action. | Device response | Indication |
|---|---|---|
| Connecting to charging | Screen activation | Mi logo and % charge |
| Low charge. | Battery pictogram | Red indicator |
| Full charge. | Green indicator | Vibration and inscription Full |
| Contact failure | Lack of response | No glow. |
Make sure the contacts on the bracelet and charger are clean. Oxidation or contamination can prevent current from passing, and the device will not turn on even when connected to the network.
💡
Wipe the contact pads with a dry soft cloth before each charge to ensure reliable contact and avoid charging errors.
What to do if the bracelet is frozen
The situation where Xiaomi Band 4 stops responding to touch and does not change the readings on the screen is rare, but it is possible.This can be caused by a malfunction in the tracker operating system or conflict when synchronizing data.
The first step is to connect the device to the charger. In most cases, the power supply causes the controller to reset hardware, and the system restarts. If this does not help, you should try a "deaf" reboot through the application.
If that doesn't work, you can try to leave the bracelet on charge for a few hours, and sometimes it takes time for the power controller to stabilize the voltage and initiate the system from a deep rest state.
⚠️ Warning: Do not try to heat the device or mechanically impact it (blows) to “revive” – this is guaranteed to bring the electronics out of order.
In rare cases, waiting for a full discharge helps if the device is still consuming energy in the background, and then the charging cycle can restore normal operation.
Comparison with other Mi Band models
The power management logic of the Mi Band lineup has remained fairly conservative for generations. Users of older models like the Mi Band 2 or 3 also didn't have the classic shutdown option. However, in newer versions, starting with the Mi Band 5 and 6, the software has become more flexible.
More modern firmware has the ability to reboot through the settings menu of the bracelet itself, making life easier for users, but turning it off is still the prerogative of battery discharge or special engineering menus that are not available to everyone.
The evolution of MIUI for Watch is gradually introducing more familiar controls, but the “always-on readiness” philosophy remains key to Xiaomi’s fitness trackers, providing instant feedback and continuous health data collection.
💡
All Mi Band models, including version 4, do not have a physical shutdown button and are controlled programmatically or via a charge/discharge cycle.
