How to Turn Off Xiaomi Mi Band 4: A Complete Management Guide

Owners of fitness bracelets often face the need to completely turn off the device. Xiaomi Mi Band 4 does not have a physical button or a separate software switch to turn off power in the usual sense. This is done for maximum compactness and protection against accidental data loss. However, situations where you need to reboot or completely discharge the battery, occur regularly.

The most common reason to find out how to turn off the Mi Band 4 is to freeze the system or to have a deep battery calibration. Unlike smartphones, there is no "Finishing Work" menu. The process of shutting down requires specific actions, which we will discuss in detail. It is important to understand that a complete shutdown is only possible by software through reset or by physical means through discharge.

In this article, we will discuss all available methods for controlling the power status of your tracker, learn how to safely restart the device without losing training data, and consider scenarios when you need a complete reset to factory settings, which will help solve most software errors that occur during operation.

Why there is no off button on Mi Band 4

The Xiaomi Mi Band 4 design implies no physical buttons on the body. All control is through the touch screen and the capacitive button under the display. The engineering solution to remove the hardware power switch is dictated by the requirements of moisture protection. Any extra hole in the case could reduce the class of protection from water and sweat.

The tracker's software shell is also optimized for constant background operation. MIUI for Wear consumes minimal energy at rest. So the concept of "switch off" is replaced here by the concept of "sleep" or "deep energy saving." When the screen goes out, the device goes into low power mode.

⚠️ Warning: Attempting to disassemble the tracker to physically disable the battery will result in loss of warranty and possible damage to the moisture layer.

The lack of an explicit shutdown function also protects the user from accidentally losing important data. If there was a button, you could accidentally turn off the tracker in the middle of a workout or sleep tracking.

Method of software reboot through settings

The safest way to turn off and re-energize the tracker is to perform a software reboot, which is available on the device's menu itself, and it helps solve minor software glitches, such as heart rate misreadability or no response to touch, which does not require a smartphone connection to perform.

To start the process, swipe your finger across the screen to the right or left until you find Settings (the gear icon), and you'll need to find System or About in the menu that opens, and you'll have Reboot, and clicking on it will trigger a short-term shutdown and system activation.

During the process, the screen will go out, and in a few seconds the Mi logo will appear. This is not a complete shutdown, but a cycle of restarting the operating system.

Using the built-in reboot function is the preferred method for solving time lags. It's safe for the tracker file system. Unlike full-biting, it only takes a couple of minutes. If the freeze problem persists after the reboot, a more radical approach may be needed.

Full reset to factory settings

If a simple reboot doesn’t work and you want to turn off the software as much as possible, use a reset.This operation will return the Xiaomi Mi Band 4 to the state it was in immediately after purchase. All accumulated data, dial settings and anchors will be permanently deleted.

To perform the reset, go to the settings menu on the bracelet itself. Find Unbind or Factory Reset. The system will request confirmation of the action. Once confirmed, the tracker will restart and clear the memory. In fact, it is analogous to turning off the system cache completely.

Open the Mi Fit app (or Zepp Life) and wait for the data update to be updated, which ensures that your statistics are not lost even if the device is cleaned.

Power management through the Mi Fit app

While there is no direct shutdown in the app, Mi Fit (Zepp Life) is the way you can control the state of the device indirectly. The tracker's untie in the app doesn't turn it off, but it breaks the Bluetooth connection. This can be useful if you want to save your smartphone power or temporarily don't want to receive notifications.

The app can check the battery status and charge level. If you plan to stay away from the bracelet for a long time, it is best to leave it with a charge of about 50-60%. Lithium polymer batteries used in the Mi Band 4 degrade faster if stored fully discharged or fully charged.

You can also update the firmware through the app. Sometimes the upgrade process requires a device to restart. If the upgrade is successful but the bracelet is acting strangely, the app may offer to reset the pairing, which is similar to finding a new device and often solves connection problems.

Use a battery health monitoring app. If you notice that the Mi Band 4 is running out faster than usual, try turning off unnecessary notifications and heart rate monitoring in the app, which will reduce the load on the processor and prolong the running time without having to turn off.

Full battery discharge as a method of shutdown

The only way to physically turn off the Xiaomi Mi Band 4 without using the menu is to wait for the battery to be fully discharged. When the charge reaches 0%, the device will shut down on its own. The screen will go out and the tracker will cease to respond to touch. This is a deep sleep state.

But this method has its drawbacks: Deep discharge is bad for Li-Po batteries; if you leave the device off for a long time, the chemicals inside the battery can cause it to be permanently damaged; the bracelet can stop charging in the future.

⚠️ Note: Do not store a fully discharged Mi Band 4 If you turn it off by discharging, charge it for a long time. 1-2 Weeks to avoid degradation of the food element.

If your goal is to completely de-energize a device for sale or disposal, the discharge method is acceptable. But for regular use, it is better to avoid scenarios where the battery drops below 5-10%.

Removal of freezes and incapacity

There are situations where the Mi Band 4 stops responding to commands and the menu is not available. The screen can burn black or show a static image. In this case, a standard shutdown is impossible. Forced reboot is required.

Try putting a tracker on the charger. Connecting to the power source often causes the system to restart. If that doesn't work, press the touch button (if it reacts) for 10-15 seconds. In some versions of the firmware, this causes a reboot.

If the software methods don't work, you can use the cold start method. Leave the bracelet on the table until it's completely discharged and turned off. Then put it on charge right away. This often brings the power controller to life.

💡

If the bracelet is stuck, put it on charge for 5-10 minutes, even if the indicator does not light up. Sometimes the battery controller needs minimal voltage to start the charging process and restart.

In rare cases, you need to flash the device, you use special utilities on the PC, but for the average user, it is risky, and you should contact the service center or the seller if the device is in warranty service.

Storage and operation recommendations

For the long-term service of your Xiaomi Mi Band 4, it is important to properly manage its condition.Do not leave the device off (discharged) on the shelf for months. Periodically, every 3-4 months, charge it to 60-70% and store it again.

Avoid extreme temperatures. Heat and frost can knock out electronics faster than software failures. If you go to a sauna or in a cold, it's better to take off the tracker or at least not actively use it at that moment.

Clean the back of the pulse sensor regularly. Dirt and sweat can interfere with sensors, making the processor work harder and waste more energy. Clean surfaces are key to working properly and saving charge.

💡

The best way to turn off the Mi Band 4 is to reboot software via the menu, and use the full discharge only in extreme cases, as it damages the battery.
