What applications to remove on Xiaomi Redmi 9: system optimization

Budget smartphone owners often face the challenge of running out of RAM and intrusive advertising that is built into the default MIUI shell. The Redmi 9, despite its popularity and availability, is not without a standard set of pre-installed software that can annoy users. Many of these programs consume CPU resources in the background, leading to faster battery drain and periodic interface brakes.

Properly cleaning the system of excess ballast can significantly revitalize the device, making it work smoother and more responsive. However, it is important to understand the difference between system components that are critical to the stability of Android, and advertising modules that can be safely disposed of. In this article, we will discuss in detail which applications to remove on Xiaomi Redmi 9, so as not to disrupt the basic functions of the gadget.

Before you take any action, you need to review the installed packages and evaluate their actual usefulness to you. Often users do not even realize that some icons on the menu are responsible for collecting statistics or displaying a news feed they never read. A competent approach to uninstallation will free up several gigabytes of internal memory, which is especially true for versions with a 32 or 64 GB drive.

Analysis of the standard set of MIUI programs

The MIUI shell installed on Redmi 9 contains a variety of services that developers believe are necessary but may not be needed by the average user, including analytics services, cloud storage, and various tools to “improve” the system that often work in vain. Understanding the purpose of each process helps to avoid the accidental deletion of critical files that can turn a phone into a “brick”.

Special attention should be paid to applications with names that contain the words "Analytics", "Feedback" or "Mi Cloud." These components constantly transmit data about your smartphone use to the company's servers, consuming traffic and battery power. If you are not using the Xiaomi ecosystem and do not plan to send error reports to developers, they can be safely disabled or deleted through special utilities.

• 📊 Mi Analytics – collects data on user behavior, application launch frequency and geography of movements for marketing purposes.
• ☁️ Mi Cloud is a cloud storage service that may be redundant if you use Google Photos or other alternatives.
• 📰 Mi Browser is a standard browser, full of news feeds and advertising notifications, which is better replaced with Chrome or Firefox.
• 🎮 Game Center is a game download platform that hangs in your memory and offers purchases even if you’re not playing.

⚠️ Note: Do not attempt to remove system components called "Security", "Settings" or "Package Installer" by standard methods, which can lead to unstable operating system operation and inability to install new programs.

To safely analyze which apps to remove, it is recommended to use the built-in Application Manager first. Go to settings, select Apps, and sort the list by size or frequency of use. This will allow you to visually assess which programs take up the most space and how long you have used them. It often turns out that heavy Google services or social networks that you do not use take up the lion’s share of memory.

Removal of advertising modules and tracking services

One of the main reasons users are looking for ways to clean up Redmi 9 is the company’s aggressive advertising policy: embedded advertising modules, known as MSA (MIUI System Ads), can pop up in the most unexpected places: in menus, in standard applications and even in the form of notifications.

The process of getting rid of advertising begins with the disconnection of the service. MSA However, more in-depth methods are often required to completely remove the system, since the standard interface does not allow the system packages to be completely uninstalled. ADB-commands or specialized uninstallers allow you to cut out advertising modules forever, preventing them from being reactivated after updates.

Beyond MSA, Xiaomi’s Mail, Music and Video apps are also worth looking at, often duplicating the functionality of standard Google players or third-party players that users install on their own, and they also have built-in mechanisms to show ads and recommend content that you may not be interested in, removing them and removing unnecessary icons from the desktop.

Importantly, once the ad modules are removed, the interface can become slightly less lively but more responsive. Some users notice that after cleaning, no more sales and promotions notifications that may have previously distracted from work stop coming-push, creating a cleaner digital environment and allowing them to focus on important tasks.

Cleaning up duplicate Google services

Xiaomi smartphones run on Android, which implies a full set of Google services. However, the manufacturer often adds its counterparts to standard applications, creating duplicates that only take up space. For example, Redmi 9 can be installed simultaneously two browsers, two video players and two file managers. Using one main set of programs is the key to order.

First, consider whether you need a second Google account or sync through your Mi Account if you don’t use it. Duplicating contacts and calendars can lead to confusion and unnecessary traffic consumption. If you prefer the Google ecosystem, Xiaomi Cloud services can be completely ignored or removed from their sync components.

Also worth looking at is Xiaomi's Downloads app and the standard Chrome bootloader. Often files are downloaded to different folders, making it harder to find the right documents. It's recommended to choose one download manager and the other one to delete or freeze, which will make it easier to navigate the file system and free up several megabytes of the system partition.

Remember, Google Play services cannot be removed by themselves, which will cause most installed applications to fail, and these are supportive applications like Google News, Google Movies or Google Podcasts if you don't use them, which can be easily found on the list of all applications and disabled by hiding them from the home screen.

System applications that cannot be touched

If you want to make the system as light as possible, users often go too far, removing components necessary for the phone's basic functionality.The Redmi 9 has a number of processes that, even if they seem useless, keep communication, sound and display running. Deleting them can cause the phone to stop seeing them. SIM-Card or lose the ability to connect to Wi-Fi.

Critical components include telephony and data services. Even if you don't need some features like VoLTE or Wi-Fi Calling, it's better to just turn them off in settings rather than delete executables. System libraries are often interconnected, and deleting one "extra" file can cause a chain error reaction.

• 📞 Telephony Provider – Provides Calls and SMS, Deletion will result in loss of communication.
• 📶 Wi-Fi Power Saving – manages the power of the communication module, important for autonomy.
• 🔊 Audio Effects – processes sound, without it, sound notifications or speaker work may disappear.
• 📱 Framework – the basic interface base, the removal of which will cause a cyclic reboot.

⚠️ Note: If you are not sure about the purpose of the process, you should search the Internet by its batch name (for example, com.android.xxx) before deleting.

Especially careful is the use of applications that have the name "System", "Framework" or "Provider". Even if they are not explicitly used, they may be required for the correct operation of security updates or specific features of the MIUI shell. In case of doubt, it is safer to simply prevent the application from running in the background through the battery settings than to remove it completely.

💡

Before removing any system application, make a full backup of data to your computer or the cloud, which will quickly restore the smartphone to work in the event of a critical error.

Using ADB for deep cleaning

For advanced users who want to clean Redmi 9 of excess software, the best tool is Android Debug Bridge (ADB). This method allows you to remove even those applications that are hidden from the average user and do not have a “Delete” button in the interface. Using ADB requires connecting a smartphone to a computer and executing several commands in the terminal.

Before starting the procedure, you need to activate the developer mode on the phone, and you need to click on the build number several times in the About Phone section, and then in the advanced settings, turn on USB Debugging. Once you connect to the PC, the computer will access the device's file system at the administrator level.

adb shell pm list packages | findstr miui


adb shell pm uninstall -k --user 0 com.miui.misys




adb shell pm uninstall -k --user 0 com.miui.analytics

These commands allow you to find packages associated with MIUI, And you can delete them for the current user without affecting the system partition, which means that even if you accidentally delete something superfluous, resetting to the factory settings will return everything as it was. ADB-Drivers to ensure stable connection.

💡

The ADB method is safer than root-rights, as it does not violate the integrity of the system partition and retains a warranty on the device, while allowing you to remove deeply integrated software.

There are also graphical shells for ADB, such as Universal Android Debloater, which make it easier to do, and in such programs, the list of applications is already sorted into categories "Safe", "Recommended" and "Dangerous", which minimizes the risk of error, and for beginners, this can be a great compromise between manual cleaning and complex commands.

Recovery of remote system components

If you find that a feature has stopped working on Redmi 9 after cleaning up (for example, the desktop wallpaper is lost or links are not opened), the deleted components can be returned. Since deletion through ADB or uninstall often occurs without completely erasing files from the system partition, they can be reactivated by a simple reinstall command.

To restore the standard state of the system, you just need to run the reinstall command for a specific package, which will return the application to the installed list and restore its rights. If you removed the applications through root rights, you may need to reflash or restore from a TWRP backup.

Often users forget that some functions are dependent on each other, for example, deleting Security can disrupt call filtering or memory cleaning, in which case it is better not to look for ways to return one file, but to do a full reset (Factory Reset), which ensures a clean installation of the system without tails from remote programs.

Regular smartphone maintenance, including deleting cache and unused applications, extends the life of the Redmi 9. Even without drastic measures such as removing system components, a simple six-month revision of installed software works wonders. The device begins to respond faster to commands, and the battery holds the charge longer, which is critical for a budget model.
