Xiaomi, Redmi and Poco smartphone owners often face a situation where the device is full of system debris out of the box. Built-in advertising, duplicate services and unnecessary Chinese applications take up precious space and consume battery power. 4PDA forum users have been compiling lists of processes that can be safely disabled or completely removed to speed up the gadget for years.
However, blindly deleting files can lead to critical errors in the operation of the MIUI or HyperOS operating system. Some components are responsible for basic functionality of calls, the Internet, or even turning on the screen. In this article, we will discuss in detail which packets are allowed to be deleted and which are strictly forbidden to touch, based on community experience and technical documentation.
You don't have to be a programmer to do the cleaning, but understanding the structure of com.android... and com.miui... is essential. We'll look at ADB removal methods and specialized utilities that allow you to safely modify the firmware without getting root rights, which will help free up gigabytes of memory and increase the autonomy of your device.
Analysis of system debris in the shell of MIUI
MIUI is famous for its functionality, but also redundancy, and developers are embedding a lot of services that ordinary users never use, including analytics, ad frameworks, and regional applications, and removing these components is the first step towards customizing the system.
You can distinguish between user applications that can be simply removed through settings and system packages that are hidden from the average user, and the latter often hang in the background, consuming CPU resources. Forums like 4PDA can find detailed lists of such packages for each smartphone model.
It is important to understand that removing the system kernel or critical libraries will result in an infinite bootloop, so before any manipulation, you need to clearly identify the purpose of each process, and do not rely on automatic cleaners that can remove excess.
- 📉 msa and daemon advertising modules are the main sources of pop-up advertising in standard applications.
- 📊 Analytics services – collect data about user behavior and send it to the company’s servers.
- 🌐 Regional Apps – Maps, browsers and stores that are only relevant to the Chinese or Indian market.
- 🔄 Background Update Processes – can constantly check for new versions, consuming traffic.
⚠️ Warning: Before removing any system components, be sure to create a complete backup of data. System recovery after deleting critical files may require flashing the device.
Safe to remove packets: 4PDA list
The 4PDA community has been testing various packages for stability for years, and as a result, a green list of apps that do not disrupt basic smartphone functionality is formed, primarily those that are connected to an ecosystem that you do not use, such as Mi Video or Mi Music, if you prefer third-party players.
Special attention should be paid to the packages responsible for advertising. Deleting com.miui.misys and com.android.adid significantly reduces the number of intrusive sentences. However, it is worth remembering that in some versions of MIUI, removing these components can cause errors in the work of the theme.
It's also safe to remove most of the partners' pre-installed games and apps, which are not deeply integrated into the system and are only used for demonstration or monetization, and their absence will not affect the speed of the interface or the quality of communication.
| Package name | Description | Risk of removal | Recommendation |
|---|---|---|---|
| com.miui.misys | Systemic advertising service | Low. | Delete |
| com.android.browser | Standard Mi browser | Low. | Delete (if not used) |
| com.miui.weather2 | Weather appendix | Medium. | Remove (if there is a replacement) |
| com.xiaomi.scanner | Scanner. QR-code | Low. | Leave or remove |

Critical Components: What to Remove Is NOT Removed
There is a category of applications that will cause a smartphone to fail, most notably SystemUI, which is the component that displays the interface, status bar, notification bar, and navigation buttons, and is guaranteed to result in a black screen if it is removed.
You can't touch phone and contact packages if you're using a standard caller. Deleting com.android.phone or com.android.contacts will make it impossible for you to make calls. Even if you plan to use a third-party launcher, the basic services should remain.
Exercise caution with the Framework components. The framework-res and miui-framework libraries contain the resources needed to run any application, and if they are damaged or deleted, they make the system unstable and cause permanent crashes.
- 🚫 com.android.systemui – responsible for the entire visual interface of Android.
- 🚫 com.miui.securitycenter – Security Center, without it, permissions may not work.
- 🚫 com.google.android.gms – Google services that are essential for most applications.
- 🚫 com.android.providers.downloads – download manager, needed for downloading files.
⚠️ Note: Attempt to delete com.miui.securitycenter via ADB This can result in you not being able to issue permissions to new applications, as this is a system restriction. MIUI.
💡
Never delete a packet that has the words “provider”, “framework” or “system” in its name unless you are 100% sure of its purpose.
Removal Tools: ADB and Xiaomi ADB/Fastboot Tools
To remove system applications without root rights, the most reliable tool is ADB (Android Debug Bridge. This is Google's official utility that allows you to control your device from a computer. USB" menu "For developers".
4PDA users often recommend using graphical shells for ADB, such as the Xiaomi ADB/Fastboot Tools by jakobedlund.This tool automatically determines the device model and offers a list of apps to remove, marking safe and dangerous packages with different colors.
The deletion process is like this: you plug in your smartphone, you run a command to delete a particular packet, and you restart. If the phone is working normally after you restart, you can move to the next item on the list, and if you make errors, it's easy to return the device to its original state.
adb shell pm uninstall -k --user 0 com.miui.misys☑️ Preparation for removal of applications
Optimizing Autonomy by Removing Services
One of the main reasons for removing system debris is to extend battery life. Background processes such as Mi Cloud (if you're not using it) or gallery synchronization can constantly wake the processor, and shutting them down significantly reduces power consumption.
You should also pay attention to services related to the smart home if you do not have Xiaomi Home devices. Constantly searching for devices on Wi-Fi and Bluetooth networks consumes charge, removing the corresponding packages can save up to 10-15% of energy per day.
Remember that after removing heavy system applications, the operating system becomes lighter, and less RAM is occupied by background processes, which allows active applications to run faster and more efficiently without causing CPU trottling.
- 🔋 Disabling com.miui.cloudservice sync saves traffic and battery.
- 🔋 Removing com.miui.personalassistant (left tape) reduces memory load.
- 🔋 com.xiaomi.voiceassistant voice assistant services can be removed if you do not use it.
💡
After removing a large number of system applications, perform a full Factory Reset, which will allow the system to reconfigure the cache and work as stably as possible with the new set of components.
Recovery of Remote Applications
If you've removed something extra in the optimization process and noticed instability, don't panic. ADB for the current user (--user 0) The reset can be restored by the reinstall command, and the application data is not physically erased from the system partition, but only hidden to the user.
To recover, you need to know the name of the package. Enter the command adb shell cmd package install-existing <name packet> or use the recovery function in graphics utilities.
In the worst case scenario, if the phone stopped booting, it will help to enter Recovery mode and reset settings, which will return all system applications to their original state, which is why having a computer at hand when modifying the system is a must.
