Owners of Xiaomi, Redmi and POCO smartphones often face incomprehensible processes in the task manager or in the list of running services. One of these processes is often labeled black or has a similar name in system logs. This causes a legitimate concern: what kind of program is it, is it not a virus, and can it be removed without harming the device? Owners of Xiaomi with MIUI and HyperOS firmware need to understand that there is a specific function behind each system process.
In fact, black is not malware or a hidden miner, it's a system component of the MIUI shell that is responsible for managing the dark theme of the interface and adapting the colors of the elements. But it's not limited to visual effects. In some cases, this process can consume a significant battery charge, which forces users to look for ways to turn it off. Let's get into detail.
It is important to note that interference with system services requires caution: the black process is directly related to rendering the GUI in dark mode, and its forced termination can lead to instability of the screen or failures in the display of menus. Before taking radical measures, you need to make sure that this process is causing problems, and not a consequence of the normal operation of the system.
Purpose and functions of the black process in Android
The main task of the black service is to dynamically change the color scheme of the interface. When you switch between a light and dark theme, this process redraws controls, application backgrounds and system widgets. In the Android operating system with the MIUI shell, this is implemented through a separate demon that monitors changes in the display settings.
In addition to the visual part, the process is involved in color calibration when you turn on Read Mode or Vision Protection. It analyzes the contents of the screen and applies the appropriate filters. If you use third-party themes from the GetThemes store, the role of this component increases, as it has to adapt third-party code to system requirements.
⚠️ Note: Attempting to delete a file associated with the black process through root rights can lead to a cyclic restart of the smartphone (bootloop.
Users often confuse this process with viruses because of its stealthiness. However, unlike malware, black does not have permission to access contacts, microphone or geolocation without the user's knowledge. It (permissions) are limited to the system level of display of graphics. Disabling this process through the developer's settings is possible, but will cause the dark theme to stop working correctly.
Technical details of the process
Why the Black Process is consuming the battery
Sometimes users notice that the background black process begins to consume battery power. This can happen for several reasons. Most often, the problem lies in the conflict of versions or the failure of the MIUI shell itself. If the system constantly tries to apply the theme, but encounters an error, the process goes into a cycle of repeated attempts, which causes heating.
Another reason could be an unoptimized third-party theme, where heavy animations and high-quality textures used in custom designs make black work harder, especially on AMOLED-enabled devices, where each pixel is individually lit and black control requires precise calculations.
- 🔋 Conflict of topics: Simultaneous use of system and third-party theme causes constant redrawing of the interface.
- 📉 Optimization error: After a firmware update, old cached data may conflict with new process algorithms.
- 🎨 Live Wallpaper: Using complex live wallpaper in combination with a dark theme doubles the load on the graphic process.
If you notice a quick discharge, try switching to a standard Classic theme and restarting the device, which will help reset the black cache and stop background activity, and in most cases, this solves the problem without the need for deep intervention.
Can I disable or remove black on Xiaomi?
The issue of removing system components is always a pressing one. The answer for the black process is that you can't completely remove it without losing the dark theme functionality. It's not a separate application that you can uninstall, but part of the system framework. However, it can be forcibly stopped or restricted in the background.
You can use Android built-in tools to limit activity. Go to Settings → Apps → All apps, search the Topics or system processes list and try to clean up the data. This won't delete the process, but resets it back to factory settings, which often eliminates power consumption errors.
☑️ Check before disabling the process
There is a method of disabling through ADB (Android Debug Bridge), but it requires a connection to a computer. The command adb shell pm disable-user --user 0 com.miui.black (the name of the package may vary) can suspend the service. But remember: black can be critical to the stability of HyperOS.
⚠️ Note: Disconnecting system processes through ADB It can cause the interface to become unreadable (white text on a white background) and can only be restored through a Windows Data reset).
Diagnosis: virus or system failure
How do you tell the difference between normal operation and malware infection? Viruses are often disguised as system services using similar names. However, the real system black is digitally signed by Xiaomi, and you can check this in the details of the application or through special ulites analyzers.
If the black process only causes heat when the theme changes, that's okay. If the phone is warming at rest and strange requests to unknown servers appear in the logs, you should check with antivirus. The built-in security scanner MIUI or Google Play Protect can detect the substitution of system files.
| Sign. | Systemic process | Virus/Mainer |
|---|---|---|
| Consumption of CPUs | Short-term change of subject | Constant, even in the plain. |
| Network activity | Local, no internet. | Continuous data transmission |
| Location of the file | System section (/system) | User folder (/data) |
| Response to antivirus | Undetectable. | Blocked or removed |
If the antivirus is silent but suspicions remain, you can use the ADB AppControl utility to view a list of all packages. Look for packages with suspicious names that have been installed recently and have no description. A true black will always have a high system priority and an installation date that coincides with the firmware date.
💡
Use Xiaomi's Security app to check permissions. Go to Permits and see if the theme-related process has access to the network. System black Internet is not required.
Impact on smartphone performance
On modern Xiaomi devices with a stock of RAM, the black process is almost invisible. It uses GPU resources efficiently and does not put a strain on the CPU. This is changing on budget models of the Redmi series or older devices, where every megabyte of RAM counts.
If you own a device with 3-4 GB of RAM, the background work of heavy graphics processes can cause micro-lags when swiping. In this case, it makes sense to simplify the visual design. Disabling animations in the Developer menu will reduce the frequency of black calls.
It's also worth considering that the system is always forced to stop the process as a mistake. The smartphone will try to start it again, creating an additional load. It's better to let the system manage the resources itself than constantly interfere with its work. Android has advanced memory management algorithms.
Optimization of the themes and interface
To minimize the impact of black on autonomy, a few rules are recommended: first of all, avoid using live themes with video backgrounds, if the battery is your priority.
Clean the theme store cache regularly. Accumulated data may slow down the service. Go to Settings → Annexes → Topics → Memory. → Clear cache.This is a secure operation that won't delete your downloaded themes, but will remove temporary files.
💡
The optimal strategy is to use static system themes and update them only when new firmware versions are released. MIUI/HyperOS.
If you notice that after installing a particular theme, the phone starts to perform worse, just delete it. Go back to the standard Classic or Default design, which is guaranteed to stop any conflicts associated with rendering the interface, and return the black process to normal operation.
