Xiaomi smartphone owners often face situations where internal storage is overflowing and the device is running slower. One of the main reasons for space shortage and performance decline is the excessive number of installed programs, many of which are rarely or not needed. On the popular Redmi Note 9 model, which runs the MIUI shell, the uninstallation process has its own characteristics that differ from pure Android.
Proper software management allows you not only to free up gigabytes of valuable memory, but also significantly extend the battery life of the gadget. Background processes of unnecessary services can consume battery power even when the screen is turned off, which is critical for active use. In this article, we will discuss in detail all available methods of removing software, from standard methods to advanced techniques for system components.
Start cleaning the device by analyzing what exactly occupies space, and users often forget about programs that were installed “just in case” or got on the phone with a purchase in the store. Xiaomi system applications cannot be removed in the standard way without obtaining superuser rights or using the system. ADB-teams, but they can be turned off, which will give a similar effect of saving resources.
Standard method of removal through the desktop
The easiest and fastest way to get rid of the excess software is to use the desktop interface. On the Redmi Note 9, this action is done in literally one touch if you are in editing mode, just click on the icon of the desired application and hold your finger until the pop-up menu appears.
In the context menu that appears, you need to select the option "Delete". If the program is a user, the system immediately requests confirmation. Once you click "OK" button, the application will be completely erased from the device along with all its cached data.
- 📱 Press and hold the icon on your desktop until the menu appears.
- 🗑️ Select the red "Delete" button or the basket icon.
- ✅ Confirm the action in the pop-up window.
However, if you don't see the delete button, it means that you have a system application or widget, which is protected from accidental removal so that the operating system doesn't malfunction, and you'll need to use the phone's settings or deeper cleaning techniques.

If the app icon is not removed from the desktop, try moving it to the Tools or Services folder, where Xiaomi system utilities are often hidden.
Managing applications through system settings
More detailed control of the installed software provides a settings menu. Here you can see the full list of all programs, including those that do not have icons on the desktop. To go to management, you need to open Settings, then select the Application section and go to All applications.
The list that opens up can sort programs by size, frequency of use, or installation date, and it helps you quickly find the "heavy" applications that take up the most space, and if you select an unnecessary program, you'll be taken to a screen of information about it, where the delete button will be available.
☑️ Pre-deletion check
It is important to note that for some system services, the delete button may be inactive (shadowed), in which case the option "Disable" is available. Disabling the application hides it from the interface and stops all associated processes, freeing up RAM, although storage space is negligible.
⚠️ Before disabling system components, make sure they are not required for other important functions such as calls, messages, or the internet.
Cleaning through the built-in security manager
The MIUI shell preloads a powerful tool called Security, which is not just an antivirus, but also a comprehensive resource management manager, and when you run the Security app, you'll see a Cleanup button that analyzes the device for junk files and rarely used applications.
Once scanned, the system will suggest removing cache and unnecessary files, but we're interested in the application management tab, where you can quickly delete several selected programs, which greatly speeds up the process of putting order in the phone, which is especially convenient when you need to remove a dozen games or utilities at once.
| Type of data | What's removed | Impact on memory |
|---|---|---|
| Cash. | Temporary files | Low. |
| Data data | Settings and logins | Average. |
| Annex | Programme | High. |
| Residues | Post-deletion files | Low. |
Using the built-in manager also allows you to identify applications that consume too much power in the background.Removing such programs often solves the problem of fast discharging Redmi Note 9. Regular check through this tool should become a habit of every user.
Removal of Unremovable System Applications
Many users want to get rid of pre-installed software like Mi Browser, Mi Video or Google services that are not removed by standard methods.
One of the safest methods is to use the command via computer and debug over USB. You will need to turn on the developer mode in the phone settings (click on the build number several times in the About section) and activate the USB debugging. Then, by connecting the phone to the PC, you can use the ADB utility.
adb shell pm uninstall -k --user 0 name packetThis command removes the application for the current user, effectively hiding it and stopping it, but leaving the ability to restore factory settings in the event of a failure. The list of packages can be found through the command adb shell pm list packages. Be careful: removing critical system components can lead to a cyclic restart (bootloop).
