Xiaomi’s Redmi Note 9 Pro series is known for its excellent price-performance ratio, but owners are often annoyed by the abundance of pre-installed software. Device owners are faced with the fact that system memory is quickly filled not only with user data, but also with built-in services that they never use. This is not just visual noise, but also a real load on the Snapdragon 720G processor’s RAM, which can lead to micro-lates in the MIUI.
In this detailed guide, we will discuss all the legal and advanced ways to clean your gadget from digital garbage. You will learn how to safely deactivate system components that are usually hidden from the user’s eyes without disrupting the stability of the Android operating system. A competent approach to software management will significantly extend battery life and free precious gigabytes of internal storage.
Analysis of the occupied space and types of applications
Before you start taking radical action, you need to audit what exactly consumes the resources of your device. Owners of the Redmi Note 9 Pro need to understand the difference between custom applications that can be removed with a simple click and system components that require a special approach. Standard system tools can only get rid of the tip of the iceberg, while heavyweights are often hidden deeper.
To start, go to Settings → Applications → All apps. Here you will see the full list of installed software. Pay attention to the items that consume the most memory and power. Often these are analytics services, advertising modules or duplicate programs imposed by regional distributors. System applications are marked with a special icon and do not have an active delete button in the standard menu.
Special attention should be paid to the so-called bloatware — pre-installed games and services that are not critical to the Android operation. their removal is safe, but requires understanding what each package is responsible for. For example, removing Mi Video or Mi Music will not affect the functionality of the phone if you use third-party players.
⚠️ Note: Before removing any system components, we strongly advise you to back up your important data. An error in selecting a package can lead to unstable interface operation.
Standard removal of user programs
The easiest and safest way to free up space is to remove apps you installed yourself or are allowed to remove through the interface. To do this, find the right icon on your desktop or app menu. Press your finger on the icon before the context menu appears, and select Delete or drag the icon to the cart if this option is available in your version of MIUI.
If there is no desktop icon, go to Settings → Applications → Application Management. Find an unnecessary program in the list, click on it and select the Remove button at the bottom of the screen. The system will request confirmation, after which the application will be completely erased along with its cache and data. This method is ideal for cleaning up games, social networks and instant messengers.
However, for many pre-installed Xiaomi applications, the delete button will be inactive (grey). In this case, the standard method will not work, and you will need to use more advanced tools, which will be discussed below.
- 📱 Find the app in the menu or settings.
- 🗑️ Press the "Delete" button or drag it to the cart.
- ✅ Confirm the action in the pop-up window.

Before removing heavy games, check if your Google Play Games account is linked to them so you don’t lose progress in the future.
Disabling the built-in MIUI services
For applications that cannot be removed in the standard way, Android provides a forced stop and disable feature.It doesn’t physically remove files from flash memory, but completely hides them from the interface, prohibits running in the background and consuming traffic. For the Redmi Note 9 Pro, it’s a safe way to get rid of annoying components like Mi Pay (if not in use), Mi Drop or regional services.
To turn off the application, go to Settings → Applications → All applications. Select the target program. If the Remove button is inactive, find the Disable or Turn off button. Once confirmed, the system will warn that the application may stop working correctly. For most embedded services, this warning can be ignored, since they are not part of the kernel of the system.
Disabled apps stop updating through Google Play or GetApps, which also saves traffic and space. However, when you reset your phone to factory settings, all the components that are disabled are activated again, a method that is good for a temporary solution or for users who are afraid to experiment with ADB.

Removal of Removed Components and FAQ
If you delete the extra packet during the optimization process or the system starts to work incorrectly, there is a recovery mechanism. For packets deleted through ADB, the adb shell cmd package install-existing command is used to return the application to its place without having to download it again, since the files remain in the system partition, simply marked as deleted for the current user.
In case of serious errors, when the phone stops loading or constantly crashes into error, only a full reset to factory settings (Wipe Data in Recovery mode) will help. This will return the Redmi Note 9 Pro to its original state, as on the day of purchase, with all the software preinstalled.
