The Redmi 9A is one of the most popular budget devices on the market, but its limited memory resources often become a bottleneck for owners: the built-in 32 GB or 64 GB are quickly filled not only with custom files, but also with pre-installed software that Xiaomi installs by default. Many users do not even know that a significant part of this software can be safely eliminated, freeing up precious space for personal needs.
The process of cleaning the system from excess software on the MIUI shell can seem confusing due to the specifics of the interface and the separation of access rights. Standard removal methods do not work for all packages, which requires more advanced system management techniques. In this article, we will discuss in detail all the available methods, from simple uninstallation through the menu to removing system components using the computer.
Optimizing Android on low-cost MediaTek processors requires a special approach to managing background processes. Remote services not only take up space, but also consume battery power, reducing the overall autonomy of the device. Proper cleaning will allow you to significantly increase the responsiveness of the interface and extend the time without recharging.
Basic removal through the settings menu
The easiest and safest way to get rid of unnecessary software is to use the built-in tools of the system. To do this, you need to go to Settings, then select the App item and click on All Apps. In the list that opens, find the desired program, tap it and select the Remove button at the bottom of the screen.
However, not all programs can be used this simple method: If the delete button is inactive or absent, this means that the application is system-based or installed with device administrator rights, in which case the standard MIUI block direct deletion to avoid critical system errors.
It’s worth noting that some of Xiaomi’s built-in services have a “Disable” option available, which hides the app icon and prevents it from running, effectively shutting the program down even though the files remain in memory. It’s a useful feature for components that can’t be removed without risking stability, but that you don’t need.
- 📱 Google’s standard apps, such as YouTube, Maps, and Play Books, are being removed as regular user programs.
- ⚙️ Mi Credit, Mi Pay and Mi Video service utilities can often be uninstalled via the application management menu.
- 🔒 System components with root or deep integration rights require the use of special tools for forced removal.
⚠️ Warning: Before removing any app, make sure it is not critical to the phone’s performance, otherwise the device may go into a restart cycle.
Users often forget to check the “Recently Deleted” section of the gallery or the manager’s file basket where some software data ends up. Complete cleanup requires checking all associated data stores after the main uninstallation procedure is completed.
Removal of pre-installed system debris
Smartphone makers often contract with third-party software developers to pre-install their products on new devices. Redmi 9A features games, news aggregators and browsers that are not part of a pure Android operating system, removing such “junk” is the first step to optimizing.
To identify these programs, carefully look at the list of all the installed applications, look for names that don't tell you anything, or services that you are guaranteed not to use. Often these programs are disguised as system programs, but when you try to remove the system calmly allows the procedure.
Special attention should be paid to MSA (MIUI System Ads) advertising services, although you can not completely remove them through the settings menu, disabling the associated services significantly reduces the amount of intrusive advertising in the interface.
- 🎮 Game launchers and demo versions of games take hundreds of megabytes and can be safely removed.
- 📰 News widgets and content aggregators often run in the background, consuming traffic and battery.
- 🛍️ Partner store apps like AliExpress or Booking are often preinstalled and not needed by all users.
⚠️ Note: Some system components can automatically recover after a reboot if sync with your Mi Account is not disabled.
The effectiveness of cleaning depends on the regularity of this procedure, and it is recommended to audit installed programs once a month, especially after major firmware updates that can return previously deleted components.
Using ADB for Advanced Removal
To remove applications that are hidden from the user in the normal mode, you will need to use the Android Debug Bridge toolkit (ADB). This method allows you to interact with the system at a deep level through a computer, giving you permission to delete almost any packet, USB-cable and on-line debugging USB smartphone.
The first step is to activate the developer mode. Go to Settings → About Phone and quickly click on the MIUI Version field seven times. After you notice that you have become a developer, go to Additional → For Developers and activate Debugging via USB.
☑️ Preparation for removal through ADB
Once you connect your phone to your computer and confirm the encryption keys on your smartphone screen, you can type in commands to delete. The command is as follows: adb shell pm uninstall --user 0 name. packet. It is important to know the exact name of the package, which often differs from the name of the application.
adb shell pm uninstall --user 0 com.android.bips
adb shell pm uninstall --user 0 com.google.android.printservice.recommendationThis method does not remove the application physically from the system partition, but hides it for the current user, which effectively frees up RAM and prevents the start of processes.
- 💻 Method ADB requires a computer operating system Windows, macOS or Linux.
- 🔌 Cable USB It should be functional and support data transfer, not just charging.
- ⚡ The speed of execution of commands depends on the performance of the PC and the driver version ADB.
⚠️ Note: Do not remove system packages that are not known to you, especially those that contain the words “framework”, “service” or “system” in the name".
Using ADB offers a lot of customization options, but it requires caution. A mistake in the name of a package can lead to the removal of an important component, so always double-check the command before executing it.
Analysis and search of packet names
The main difficulty with ADB is identifying the correct packet names, and MIUI displays beautiful names like "Weather" or "Calculator," but they're called differently for the system, like com.miui.weather2. There are special utilities to find these names.
One of the most convenient solutions is to install an ID application directly on a smartphone, such as the App Inspector or Package Name Viewer, which shows the technical name of any installed application that can be copied and used in the ADB command line.
List of safe packet removal
There are also online databases and forums where enthusiasts compile lists of safe to remove packages for specific models, such as the Redmi 9A. Using verified lists minimizes the risk of system damage.
| Title of the annex | Packet name (example) | Security of removal | Impact on the system |
|---|---|---|---|
| Mi video | com.miui.videoplayer | Safe. | Nothing. |
| Google Play Music | com.google.android.music | Safe. | Nothing. |
| System launcher | com.miui.home | Critically. | Break the interface. |
| Phone (Calls) | com.android.dialer | Critically. | Inability to call |
When searching for packages, look for prefixes. Google apps usually start with com.google.android, Xiaomi apps start with com.miui or com.xiaomi. Third-party software has its own domain names that match the developer.
Cleaning cache and residual files
Even after successful removal of the application, the smartphone’s memory may still have its tails — folders with configuration files, cache and logs — that are not automatically deleted and over time occupy a substantial amount of built-in storage.
To manually clean up residues, use the built-in Security app or third-party file managers like Files by Google or Total Commander. Go to the root folder of internal memory and look for directories with remote program names.
💡
Use the “Storage Analysis” feature in your phone’s settings to visually see which folders take up the most space after you delete apps.
Pay special attention to the Android/data and Android/obb folders. This is where game and heavy-app data is stored. If you delete a game but the folder with its name (often containing the developer domain) remains, you can easily delete it manually.
- 🗑️ Folders with names of remote applications in the root of memory can be deleted without fear.
- 📂.log and.tmp files in system directories are often temporary and secure to clean.
- 🔄 Regular cleaning of browser and messenger cache frees up gigabytes of space.
You should not delete files that you do not understand, especially if they are in system partitions, but rather focus on the obvious remnants of remote software so as not to disrupt the remaining programs.
Recovery of Remote System Components
If a component is removed and the system is unstable or an important function is lost, the remote application can be returned, and since the ADB method does not physically erase files, but only disables them for the user, the recovery is quick and without loss of data.
To return the application, use the adb shell cmd package install-existing name.packet.This instruction forces the system to register the package again as active for the current user. If the application was removed completely (which is only possible with root rights), it will need to be re-installed from the store.
💡
The ADB method is reversible: any application remote through it can be restored by install-existing command without flashing the phone.
If the phone stopped booting after unsuccessful experiments with system files, you may need to log in to Recovery mode. In this mode, you can reset to factory settings (Wipe Data), which will return all system applications to their original state, but delete personal data of the user.
It is important to keep a list of deleted packets, especially if you remove many components at once, which will allow you to quickly identify the culprit of the problem and restore it to work if necessary.
