Xiaomi smartphone owners often face a situation where the purchased device is overflowing with pre-installed software. Redmi Note 9 Pro was no exception, offering users a whole range of services that may not be needed in everyday use. Excess background processes not only takes up precious RAM, but also accelerates battery discharge, reducing the overall autonomy of the gadget.
Competent system optimization allows you to significantly improve the performance of the device, the operating shell MIUI has mechanisms that allow you to safely deactivate unnecessary components without the need to obtain root rights, which opens up a wide range of opportunities for customization and speed up the smartphone even for inexperienced users.
In this article, we will discuss in detail which components of the Redmi Note 9 Pro system are subject to safe shutdown. We will look at Google’s built-in services, Xiaomi advertising modules and standard utilities that duplicate the functionality of third-party programs.
Analysis of pre-installed software and its impact on the system
Xiaomi’s Android system contains many background services that consume CPU resources. Background processes can quietly load a device even when the screen is off. Understanding what each package is responsible for is critical before making any configuration changes.
Many users mistakenly believe that removing or disabling standard applications will lead to unstable work. However, MIUI has a clear separation between system-critical components and user software.
How to check the expenditure of resources?
Some services are deeply integrated into the manufacturer’s ecosystem, such as Mi Video or Mi Browser, which can be used by the system to open certain types of files by default, and will require the installation of alternative solutions beforehand.
- 📉 Reducing the load on RAM: Freeing up RAM for games and heavy applications.
- 🔋 Charge savings: Reducing the number of active background services prolongs running time.
- 🚀 Interface Acceleration: Animations get smoother when the system doesn’t need to service unnecessary processes.
Safely disable Google services on Redmi
Google's ecosystem is an integral part of Android, but not all of its components are necessary for every user. On the Redmi Note 9 Pro, you can find a number of apps that you never use, and you can safely deactivate them through the settings menu.
For example, if you don't use Google Drive cloud storage to sync files, you can pause it, as does YouTube video if you only watch content through a browser, or Google Play Music (older firmware versions).
⚠️ Warning: Never try to disable Google Play Services or the Google Play Store, which will cause most third-party applications to fail and disrupt the operation of the service_push_notice.
To manage these components, go to Settings → Applications → All apps. Find an unnecessary service in the list, click on it and select the Disable button. The system will warn about the possible consequences, but for the applications listed above, they are minimal.
Also, you should pay attention to synchronization. If you don't need to constantly upload photos to Google Photos, turn off autoload in the settings of the app itself, which will significantly reduce network activity and battery consumption.
Removing Advertising and System Applications by Xiaomi (MSA)
One of the main reasons for the Redmi Note 9 Pro’s slowdown is the MSA (MIUI System Ads) advertising engine, which is responsible for displaying banner ads in standard utilities, and turning it off is the first step towards a comfortable smartphone use.
To deaktivirovat' ads, you first need to turn off recommendation receipt. Go to the Mi Account acca settings, find the Authorization and Registration section, and uncheck the msa box. After that, wait 10 seconds and confirm the disconnection.
Path to disable MSA: Settings -> About Phone -> (click multiple times on MIUI version) -> Rights and Permissions -> msa -> DisableBesides MSA, it’s worth considering disabling other standard Xiaomi apps if you prefer third-party counterparts. For example, the Mi Browser browser often imposes news feeds, and the Mi Video player may not support the formats you want without codecs.
- 🛑 GetApps: the app store from Xiaomi, which often sends notifications about new products.
- 📰 Mi News: news aggregator that works in the background and consumes traffic.
- 🎵 MIUI Music: a standard player that can be replaced with a more functional one.
💡
After disabling the MSA, restart the smartphone so that the changes take effect completely and the cache of the advertising modules is cleared.
List of system applications to disable: table
Below is a detailed table of components that can be safely deactivated on the Redmi Note 9 Pro, based on a review of the stability of the system after the changes are made.
| Title of the annex | Function | Recommendation | Effects of disconnection |
|---|---|---|---|
| Xiaomi Mail | Mail client | Disable if not in use | You cannot open mail through a standard application. |
| Mi Drop | File transfer | Disable (there is BetterShare) | The old file transfer method will become unavailable |
| Google Maps (Mapping) | Offline maps | We can turn it off. | Navigator work without Internet will be limited |
| Google Movies | Video rental | Shut down. | Service does not work in Russia, safe removal |
| Printing by Wi-Fi | Printer drivers | Disable if there is no printer | Inability to print from the phone without installing drivers |
It's important to understand the difference between deleting and disabling. With standard MIUI tools, most system packets can only be disabled. They stay in memory, but they stop running and consuming resources. Complete removal will require more sophisticated methods like ADB.
If you accidentally disable an important component, you can always activate it back, so you can select Enable from the app management menu, and the system automatically restores all connections and permissions.
Using ADB for deep cleaning of the system
For advanced users who want to completely remove unremovable Redmi Note 9 Pro system applications, there is a method using ADB debugging (Android Debug Bridge), which allows you to work with the system at a deep level without superuser rights.
Before starting the procedure, you need to activate the developer mode. → About the phone and seven times quickly click on the version MIUI. Then on the menu Additional. → For developers, insert a paragraph USB-debugging.
☑️ Preparation for work with ADB
Once you connect your smartphone to your computer and confirm the encryption key on your phone screen, you can use commands to delete packets. For example, the command to delete the Mi Browser will look like this:
adb shell pm uninstall -k --user 0 com.android.browser⚠️ Attention: Use of teams ADB Removing critical system packages (e.g., Security or Settings) can lead to a cyclic bootloop and the need to flash the device.
There are graphical shells like Xiaomi ADB/Fastboot Tools or ADB AppControl that make this process easier. They display a list of apps with a description and allow you to delete them in one click, which reduces the risk of error for beginners.
Optimizing autoload and background activity
Even after disabling the extra applications, some programs may try to start when the system starts. MIUI has a built-in autoboot control tool that helps control this process, which allows you to prevent applications from running with the phone.
To access this functionality, open the Safety app (green zipper icon). Go to Permissions → Autorun. Here you will see a list of all programs that start automatically. Leave only messengers and alarms on.
Also worth checking the battery settings for each important application. In the charge saving menu, you can select No restrictions for messengers to make notifications arrive on time, and Limit activity for rarely used utilities.
💡
Comprehensive optimization includes not only the removal of applications, but also the competent setting of their access rights and background activity.
Regularly checking the list of working processes helps keep the Redmi Note 9 Pro in good shape. Periodically check the task manager to make sure that the "hanging" processes of already deleted or disabled programs are not stuck in memory.
