Wearable electronics owners often face the need to completely shut down the device, whether to save charge during prolonged downtime or eliminate software failures. The question of how to turn off the Xiaomi Band 4 is one of the most frequent, since the design of this tracker does not imply the presence of a physical button or a separate power key. Energy management is implemented exclusively by software through a conjugated smartphone, which can confuse beginners who are accustomed to classic gadgets.
The absence of a mechanical switch is a clever engineering solution that keeps the body waterproof and reduces the size of the device. To turn off the fitness bracelet, the user needs to consult the interface of the mobile application, which acts as a remote control. The deactivation process is simple, but requires understanding the logic of the operating system of the bracelet and the correct actions in the menu Mi Fit or Zepp Life.
In this article, we will discuss in detail all the available ways to stop the tracker, from a regular shutdown to a forced reboot. You will learn the difference between a connection break and a complete power outage, and also get answers to questions about eliminating freezes. Proper control of the condition of the device will prolong the battery life and help avoid errors in the operation of sensors.
Software shutdown via Mi Fit or Zepp Life app
The main and most secure way to completely turn off the Xiaomi Mi Band 4 is to use the official mobile app. Since there is no off menu on the bracelet itself, all commands come from the phone via a Bluetooth connection. First, make sure your smartphone is within range of the tracker and Bluetooth is activated. Open the Zepp Life app (formerly known as Mi Fit), which you used to initially set up the device.
Go to the device profile by clicking on the bracelet icon at the bottom of the screen or in the "Profile" section. Here you need to find the "Device settings" or "Settings" item, where the main parameters of the operation are hidden. In the list of options, you should scroll the menu to the bottom where the "Unlock" or "Unbind" button is located. Pressing this button will break the connection, but will not turn off the tracker permanently.
To completely turn off power in some versions of firmware and applications, you need to find a specific option "Stop" or "Power Off". If such a button is not explicitly, then untying is considered the standard procedure, after which the device goes into standby mode and after a while it goes out itself.
- 📱 Open the Zepp Life app and make sure you have an active connection to the bracelet.
- ⚙️ Go to Profile and select your Xiaomi Band 4 from the list of devices.
- 🔌 Find the Unbind option to break the pairing and stop synchronization.
- 🔋 If available, use the “Switch Off” command to immediately stop screen and sensors from working.
⚠️ Warning: After the device is unplugged, all workout data that was not synced to the cloud may be lost.
It is important to understand that after the command to turn off, the monitor screen will go out, and the vibration will stop, the device will go into a state of deep sleep, recovery will occur only after connecting the bracelet to the charger, since the alarm clock does not work when it is off.
Absence of physical button and design features
The Mi Band 4 is a monolithic capsule module devoid of any protruding controls. Xiaomi engineers have abandoned a physical button in favor of a touch screen and a built-in accelerometer that responds to the lifting of the wrist. This solution makes the device more airtight, which is critical for the claimed 5 ATM water protection.
The absence of the Power button means that the user cannot physically interrupt the power circuit mechanically. The whole logic of on and off is tied to a power controller that is controlled by software. If the bracelet is stuck and does not respond to touch, you cannot simply press and hold the button, as on a smart watch or phone, in which case you have to resort to methods of forced reboot through discharging or reconnecting to charging.
Why would a button hurt?
The sensor area occupies almost the entire face of the capsule, and the touchscreen here is capacitive, which provides high sensitivity, but also means that the control is only possible if there is a charge in the battery. If the battery is completely dead, the device goes into a state close to turning off, but it will still need external energy to start again.
- 🚫 On the case of Xiaomi Band 4 there are no mechanical switches, indentations or holes for resetting.
- 💧 Monolithic design provides a high degree of protection from sweat, rain and immersion in water.
- 🖐️ All interactions occur through sensory OLED-A screen that doesn’t work without a battery charge.
Understanding the design features helps avoid trying to disassemble or push an invisible button, which can damage the body, and tightness is the main trump card of this model, and it depends on the absence of unnecessary holes.
What to do if the bracelet is frozen and does not respond
When Xiaomi Band 4 stops responding to touch and does not display information, it is not common, but requires immediate intervention. Most often this occurs due to a malfunction of the firmware or overflow of the memory buffer. Since the standard menu is not available, you need to perform a forced reboot, which is actually a cycle of off and on.
The most effective method in this case is to connect the bracelet to the charger, and even if the device is dead, the voltage on the contacts causes the power controller to initiate the process of booting the operating system. Connect the capsule to charging, wait a few seconds until the Mi logo appears, and then disconnect it. In most cases, this brings the tracker back to life.
☑️ Actions when getting stuck
If charging doesn't work, try the "deep discharge" method. Leave the bracelet disconnected from the phone for a few days until the battery runs out completely and the device shuts down itself. Then put it on charge. This method works like Hard Reset for many electronic devices, resetting temporary errors in RAM.
⚠️ Warning: Do not attempt to open the case or shorten the charging contacts with metal objects.This will lead to irreversible damage to the electronics and loss of warranty.
In rare cases, the cause of the freeze is a malfunction of the sensor or plume. If neither charging nor waiting for discharge helped, there may be a hardware breakdown, in which case the software methods of disconnecting or restarting are no longer effective, and you need to contact the service center.
Difference Between Uncoupling, Rebooting and Shutting Down
Users often confuse these three concepts, although they denote fundamentally different states of the device. Unbind is the process of breaking the Bluetooth connection between the bracelet and the phone, while the tracker itself continues to work, counting steps, pulse and displaying time, simply stopping transmitting data to the smartphone.
Reboot is a short-term shutdown and then turn on the device. At this point, the operating system closes and starts again, which allows you to clear the cache and fix minor software errors. On the Xiaomi Band 4, there is no direct Reboot button in the menu, it is emulated by connecting to the charger or completely discharging.
Power Off is a complete power outage of all components of the device. The screen goes out, the sensors go out, Bluetooth is down. In this state, the bracelet uses no energy and does not perform any functions. To exit this mode, you need to have an external influence - connection to the current source.
| Action. | Screen status | Battery consumption | The need for a telephone |
|---|---|---|---|
| Uncoupling | It's working. | There is. | Required for the team |
| Reboot. | Gasnet/Included | Short-term | Not required (through charging) |
| Shutdown | Off. | No. | Required for the team |
| Sleep (timer) | Off. | Minimum | Not required |
Understanding these differences will help you manage your device properly, for example, to save charge on the journey, it is better to use a full shutdown, and to eliminate interface glitches, it is enough to simply reboot through a network connection.
💡
The undocking of the device does not turn it off, but only breaks communication with the phone. To completely stop working requires a command to turn off or discharge the battery.
How to save charge: screen settings and notifications
If your goal is to turn off the Xiaomi Band 4 not completely, but only to minimize energy consumption, you should pay attention to the display settings. The screen is the main consumer of energy in any wearable device. In the application you can activate the "Raise the wrist to turn on the screen", but even more effectively turn it off and turn on the screen only by touch or on schedule.
Use the Do Not Disturb function, which stops the bracelet vibrating and highlighting the screen when the notifications are in, saving you a lot of charge, and you can set this mode directly on the bracelet or through the app by setting time intervals, for example, for sleep.
- 🌙 Set a sleep timer in the app so that the screen automatically goes out at a predetermined time.
- 🔕 Disable unnecessary notifications from apps you rarely use in notification settings.
- 🎨 Use black and white dials without animation, as OLED-Black pixels do not consume energy.
- 📉 Reduce the brightness of the backlight to the minimum comfortable level in the device settings.
It's also worth noting that constantly searching for a Bluetooth signal when a communication break also consumes battery. If you know the phone is far away, it's best to temporarily turn off the Bluetooth on the phone or untie the bracelet so it stops trying to restore connection.
Frequent questions and problems when disconnecting
When trying to turn off or restart a device, users may encounter various difficulties, such as the Unplug button may be inactive if the phone is far from the bracelet. Make sure the devices are nearby. Another common problem is that the bracelet does not turn off after the command. This may mean that the command did not reach the device due to a bad signal or the phone's Bluetooth module freezes.
Sometimes people ask if the bracelet can be turned off if the phone is lost or broken. Unfortunately, without the phone, you can not perform a regular shutdown, because the menu of the bracelet does not contain this option, in which case you only have to wait for the battery to completely discharge, which will take from 10 to 20 days depending on the residual charge and usage activity.
💡
If the bracelet warms up when charging and does not turn on, immediately disconnect it from the mains. This may indicate a bloating battery or short circuit.
It is better to keep the device in working condition, periodically recharging it than to keep it off for months.
