Smartphones series Redmi 9C are often the first serious gadgets for users, but the standard shell MIUI can be filled with pre-installed software that is not always needed by the owner. Owners of the Xiaomi Redmi 9C device are faced with a lack of internal memory, as the basic version has only 32 or 64 GB, a significant part of which is occupied by the system and system debris. Removal of unnecessary programs is the first step to speed up the device and free up valuable space for personal files.
The cleaning process can range from simply removing shortcuts to deeply uninstalling system components through a computer. It is important to understand that some applications, such as Google Play Services or system security services, cannot be touched to avoid disrupting the performance of the entire device. In this article, we will discuss safe cleaning methods specifically for the Redmi 9C model with a MediaTek Helio G35 processor.
Before any manipulations begin, you need to understand the risks: deleting critical system files can lead to a cyclical reboot or complete inoperability of the interface. We will look at methods of varying degrees of complexity, from standard Android settings to the use of debugging tools for advanced users.
Analysis of the occupied space and types of applications
Before you start removing, you need to audit what exactly is installed on your Xiaomi Redmi 9C. In the MIUI shell, all programs are divided into custom programs that you downloaded yourself and system programs implemented by the manufacturer. User software is removed without restrictions, whereas the system requires special rights or special commands.
To start, go to the memory management menu to see the details of each program, which will help identify hidden resource eaters who may not have a label on the desktop, but are actively working in the background, consuming RAM and battery power.
- 📱 User applications – installed by the owner from Google Play or APK-files are deleted in a standard way without restrictions.
- 🛠 System applications MIUI — Xiaomi built-in services (Mi Browser, Mi Video, GetApps), the removal of which is possible, but requires caution.
- 🤖 Google services are the basic components of Android (Gmail, YouTube, Chrome), the disabling of which can affect the operation of other services of the corporation.
- 📡 Operator software – programs from mobile operators, often preinstalled in firmware for a specific sales region.
Special attention should be paid to applications that do not have an interface, which can be malicious or just residual files after a system update. If you see a process with an obscure name, it is better to first check it on the Internet before you force it to stop or delete.
⚠️ Warning: Before removing any system components, be sure to back up your critical data. In some cases, removing key services may require a complete reset to factory settings.
Standard removal through smartphone settings
The safest and most affordable method for any user is to use an integrated application manager, which does not require a connection to a computer and eliminates the risk of accidental damage to system files, since the interface simply will not allow you to remove critical components.
To remove an unnecessary program, go to the settings section, where you store information about all installed system components. Here you will see a complete list, sorted by frequency of use or size. For the Xiaomi Redmi 9C, this menu can be called "Applications" or "All Applications" depending on the version of MIUI.
☑️ Standard removal algorithm
When you select a particular application, you will open a screen with information about it. If the program is user-generated, the delete button will be active and visible. In the case of system applications, this button can be hidden, replaced with "disable" or absent, which is the security mechanism of the Android operating system.
Sometimes when you remove heavy games or cache applications, the system can handle the request for a long time, so you don't have to switch between the menus or try to run another heavy program so as not to cause the launcher interface to freeze.
Remove from the MIUI Application Management Menu
There is an alternative, faster way to access program management that many users ignore in the MIUI shell, which allows you to delete multiple applications at once, saving you a lot of time when you first set up the new Redmi 9C.
This method doesn't require you to dig deep into the settings menu, but just press your finger on an empty desktop space or make a gesture (tweak with two fingers) to go into editing mode. In the bottom menu, you often see the Settings or Control icon, where you can find the item for mass removal.
However, the more reliable way to use MIUI is to use the built-in Security app, which is the control center of the system and contains a module for cleaning memory and deleting programs, which has broader rights than a standard Android Manager.
- 🧹 Open the Security app (green shield) from the standard Tools folder".
- 📂 Select “Clean” or go to “Application Management".
- ✅ Check all programs you plan to eliminate.
- 🗑 Click the "Delete" button at the bottom of the screen and confirm the action.
The built-in Security tool is preferable because it is better integrated into MIUI processes and cleans residual files correctly after uninstallation, helping keep the device clean and preventing the accumulation of digital debris.
💡
Use the Cleanup feature in the Security app immediately after removing heavy games – this will delete the remaining cache files, which usually take up hundreds of megabytes.
Using ADB to remove system software
Removing deeply embedded applications that are not removed by standard methods will require the use of a computer and the Android Debug Bridge (ADB) tool, which allows you to send commands directly to the Xiaomi Redmi 9C operating system, bypassing user interface restrictions.
Before starting the procedure, you need to activate the developer mode on your smartphone. To do this, go to the About Phone settings and quickly press 7 times on the MIUI version. After that, a new section "For developers" will appear in the "Additional" menu, where you need to turn on "Debugging by USB".
You need to download ADB platform tools from Google's official website. Once you unpack the archive, open the command line in the tool folder. Connect the phone with a cable and enter a command to check the connection. If done correctly, a request for debugging permission will appear on the smartphone screen.
adb devices
adb shell pm list packagesThe pm list packages command will display a list of all packages. Find the name of the package to be removed (e.g. com.miui.videoplayer), and use the uninstall command. Be extremely careful: removing the SystemUI or Phone system package will make the phone unusable without flashing it.
| ADB Team Team | Action. | Risk |
|---|---|---|
| adb shell pm uninstall -k --user 0 <package_name> | Removal of the application for the current user | Low (can be reset by resetting) |
| adb shell pm disable-user --user 0 <package_name> | Disabling the application without deleting | Minimum |
| adb shell pm install-existing <package_name> | Recovery of Remote System Application | Safe. |
⚠️ Attention: Uninstall team in ADB It does not physically delete the file from the partition, but hides it for the current user. This is safer than complete deletion, since it allows you to restore the application with the install-existing command.

Third-party utilities for uninstallation
If using the command line seems too complicated, there are graphical shells for ADB that automate the process.One of the most popular and proven programs for Xiaomi owners is Universal Android Debloater. It runs on Windows, macOS and Linux.
These programs automatically identify the list of safe applications to remove and red-code the dangerous system components, which greatly reduces the risk of accidentally removing a critical service, and the interface allows you to see the description of each package, which helps you make an informed decision.
Another option is to use cleaner applications that are installed directly on your smartphone, such as System App Remover, but they often require root rights, which can be difficult to obtain on modern versions of MIUI and lead to a loss of warranty.
- 🖥 Universal Android Debloater is a powerful PC tool with a graphical interface and a list of secure packages.
- 📱 System App Remover – an Android application that requires root access for deep cleaning.
- 🔧 ADB AppControl is a convenient program for Windows that allows you to manage applications over Wi-Fi or USB.
When using third-party software, always check the source of the download. Downloading tools from dubious sites can lead to infection of the computer or smartphone with malicious code that masquerades as a useful utility.
💡
Using graphical shells for ADBs like UAD is significantly safer for beginners than manually entering commands, thanks to built-in lists of recommended packets to remove.
Recovery of Remote System Components
While optimizing the system, Redmi 9C users may find themselves in a situation where a remote application is still necessary. Fortunately, ADB makes it easy to get things back into place if you haven’t erased the recovery partition data.
To recover a packet removed through ADB, you just need to use the installation command of an existing packet. The system will find the installation file in the hidden partition and restore the application to the current user. This only works if the application was removed by the uninstall --user 0 command, and not physically erased.
If you delete a critical component and the phone stops loading (it’s in bootloop), you’ll need to log in to Recovery mode. You can reset the Wipe Data menu, which will return the phone to factory status with all the standard apps.
Therefore, regular backup is a must-have habit for any Android owner.
⚠️ Warning: If after removing the system component, the phone starts to work incorrectly (sound disappears, the network does not work), immediately restore the deleted packet.
