Owners of popular fitness trackers often face a situation where it is necessary to completely turn off the device.This may be necessary to save battery power if you do not use the gadget for a long time or in the case of software failures. Xiaomi Mi Band 4 does not have a physical on or off button, which creates a certain confusion for beginners.
Many users mistakenly believe that it is enough to remove the bracelet from your hand or wait for the battery to completely discharge. However, a smartwatch is a complex electronic device that requires the operating system to shut down correctly. Wrong actions can lead to an interface freeze or incorrect display of health data. In this article, we will discuss in detail all ways to manage the power of your tracker.
It’s worth noting that the term “off” in the context of the Mi Band 4 often implies either a sleeper or a full factory reset. Understanding this difference is critical to proper maintenance of the gadget. We’ll look at standard methods, working with the settings menu and actions in emergency situations when the device stops responding to touch.
Features of the Mi Band 4 power system
The power architecture of Xiaomi fitness bracelets is designed to minimize the power consumption in standby mode. When you are not interacting with the screen, the device automatically goes into deep sleep mode. In this state, the tracker processor operates at minimum frequencies, polling the sensors only periodically, which is why simply removing the wrist bracelet from the wrist is not enough to completely turn it off.
The main source of energy in the fourth model of the Mi Band is the built-in lithium polymer battery with a capacity of 135 mAh. The device's power controller distributes energy between the display, Bluetooth module and pulse sensor. With active use of Bluetooth connection and constant monitoring of heart rate, energy consumption increases significantly. Understanding these processes helps the user to more effectively manage the device's resources.
Unlike smartphones, there's no way to quickly pull out the battery. All the energy management processes are software-based. The tracker's operating system strictly controls the charging and discharging cycles. If you're planning to keep the gadget for long-term storage, it's important to understand that even when it's off, there's still a minimal leak current, albeit in microscopic values.
⚠️ Warning: Long-term storage of a fully discharged lithium polymer battery can cause irreversible damage and bloating.Be sure to charge at least a minimum of a charge before sending the tracker for storage 50-60%.
All functions require regular interaction with your smartphone. Synchronizing data through the Mi Fit app (or Zepp Life) also affects your energy balance. If you notice that the device discharges quickly even in simple ways, perhaps the problem lies not in the software that requires rebooting.
Staff shutdown through the settings menu
The safest and most effective way to disable the Xiaomi Mi Band 4 is to use the device’s built-in menu, which ensures that all background processes are completed correctly and user data is saved if you don’t plan to reset. The tracker’s interface is logical, though not immediately obvious to those who are used to physical buttons.
To access the off menu, you need to unlock the bracelet screen by touching the touch area or raising your wrist (if the function is active). Then you should scroll through the list of functions to the bottom, there you will find the option "Additional" or immediately "Settings", depending on the firmware version and region.
The algorithm of actions is as follows:
- 🔍 Find and select the “Settings” item (cog icon) in the main menu of the bracelet.
- 📉 Scroll down the list of parameters before the System or About option appears».
- 🛑 Select the option “Switch off” and confirm the action by pressing the touch button.
Once confirmed, the shutdown animation will appear on the screen, and the display will go out. The tracker will go to a state of complete rest. To turn it back on, you will need to connect the device to the charger. This is an important nuance: there is no software button activation in this model, the system starts automatically when power is applied.
⚠️ Warning: When you turn off through the menu, all unsaved workout data, if it is going right now, may be lost.
Reboot and reset to factory settings
Often users look for a way to turn off the device when it freezes or is not working properly. In such cases, a simple shutdown may not be enough. Reboot allows you to update system files and clear RAM without deleting personal data. If the problems are serious, a complete reset (Unbind) may be necessary.
To reboot or reset, you need to revert to the settings menu. Under System or Additional, you will find the appropriate items. Reboot takes only a few seconds, while reset requires confirmation and takes longer. Factory settings return the bracelet to the "out of the box" state, removing all bindings and data.
The differences between these operations are significant:
- 🔄 Reboot: Quick system update, user data is saved, communication with the smartphone is not lost.
- 🗑️ Unbind: Complete deletion of data, disconnection of connection with the application, return to factory parameters.
- ⚡ Shutdown: Full power out, data storage, charging required to turn on.
Use Reset only in extreme cases when other methods do not help, or before selling the device, after reset, you will need to re-connect the bracelet to the smartphone through the Zepp Life app. This will take some time, as you will need to reconfigure the dials and notifications.
☑️ Preparation for resetting settings
What to do if the bracelet is frozen and does not respond
When the tracker screen goes out or the image freezes and the sensor stops responding, it is rare but possible, and this can happen due to a firmware failure or a synchronization conflict, in which case the standard menu becomes unavailable, and the user is stuck, not knowing how to turn off the device.
The first step should always be to try to wake up the system. Connect the bracelet to the charger. Often the voltage application causes the power controller to reset, and the device comes out of the freeze. If the screen catches fire and responds to touch, immediately perform a regular reboot through the menu, as described above.
If charging doesn't work, you can try the "deep discharge" method. Leave the device to lie down until the battery runs out completely and the bracelet shuts down itself. Then put it on charge. However, this method is not recommended to be used often, since deep discharge is harmful to Li-Pol batteries.
Secret method of rebooting through the app
In rare cases, long-term retention of the touch button (simulating a long press) helps, although in Mi Band 4 this does not always work programmatically. If nothing helps and the bracelet warms or behaves strangely, it is best to leave it alone for a few hours and then try to charge again. If the problem recurs, a firmware update may be required.
Comparison of nutrition management methods
For the convenience of users, we have systematized all available ways to manage the state of Xiaomi Mi Band 4. Each method has its own goals and consequences. The choice of the right approach depends on your current task: whether you just need to save charge, fix a bug or prepare the gadget for sale.
Below is a table that will help you quickly navigate the methods:
| Method | Data retention | Implementation time | Inclusion |
|---|---|---|---|
| Sleeping mode. | Yes. | Instantly. | Raising the wrist |
| Shutdown (Menu) | Yes. | 5-10 seconds | Charger |
| Reboot. | Yes. | 15-20 seconds | Automatically. |
| Reset (Unbind) | No. | 30 seconds | Automatically. |
As you can see from the table, sleep mode is the main state of the device between use. Complete shutdown is rarely required. Reboot is the best friend with small glitches, and reset is a radical remedy. Understanding these differences will prolong your gadget's life.
💡
Main conclusion: For everyday use, it is enough to simply remove the bracelet from the hand; a complete shutdown is only necessary for long-term storage or deep diagnosis.
Optimizing work and saving energy
Instead of constantly turning the device on and off, it is much more efficient to set it up correctly. Optimizing the settings allows you to significantly increase battery life without having to resort to emergency measures. Modern Xiaomi trackers have excellent energy saving algorithms if you activate them correctly.
First of all, pay attention to the settings of the screen. You can reduce the brightness of the display, and reduce the backlight time to a minimum, and you should also turn off the function "Raising the wrist to turn the screen on" if you often make sharp movements of your hands to avoid false switches, which will save a significant percentage of charge.
Additional recommendations for savings:
- 📉 Turn off continuous pulse monitoring by leaving the measurement on schedule or manually.
- 🔕 Reduce the number of notifications coming from your phone, leaving only the most important ones.
- 🌙 Use Do Not Disturb at night to turn off the vibra and screen.
Regular synchronization is also important, because if the bracelet hasn't been in contact with your smartphone for a long time, it can accumulate data, which in rare cases affects your performance, and try to open the Mi Fit or Zepp Life app at least once a day to update your statistics.
