Owners of the Xiaomi Redmi 7A smartphone often face a shortage of internal memory within a few months after buying the device.This model, despite its reliability and availability, initially comes with a limited amount of storage, which is quickly filled with cache, updates and preinstalled software. System debris and background processes can significantly slow down the gadget, making navigation on the menu ragged and annoying.
Cleaning your device of excess software is not just a way to free up a couple of gigabytes, but also the ability to extend the life of the battery, since less running processes means less energy consumption. In this article, we will discuss in detail all available methods of removing programs, from standard uninstallation to the use of advanced debugging tools. Redmi 7A runs on the basis of the MIUI shell, which has its own features of access control.
Before we take drastic measures, it is important to understand the difference between user and system components. Deleting critical system files can lead to unstable operating system performance or even a complete failure of the device to boot. We will look at safe cleaning methods that ensure that the basic functions of your smartphone are safe.
Basic removal of user applications through settings
The easiest and safest way to free up space on Redmi 7A — Removing programs that you installed yourself from the Google Play store or downloaded as APK-It doesn't require any additional rights or connection to your computer, just go to the settings menu, select the App section, then go to All Apps, and it shows the complete list of installed software, sorted alphabetically or by date of use.
Find an unnecessary program in the list, click on its name to open the management page. At the bottom of the screen you will see the Remove button. If the program is active, the system may request confirmation of action. The standard uninstall completely deletes the executable files, cache and user data associated with this application. This is ideal for games, social networks or utilities that you have stopped using.
However, some applications may not have an active delete button, which means that they are either system components of the MIUI shell or have device administrator rights. In the first case, the button will be gray or absent, in the second case, you will need to pre-removal of administrator rights in the appropriate section of security settings. User applications always have an active delete button, unlike the system components of Google or Xiaomi.
💡
Before mass removal of apps, go to Google Play → Profile → App and Device Management → Used to see which programs take up the most space.
Working with MIUI and Google system applications
Redmi 7A owners often complain about the abundance of pre-installed software that cannot be removed in the standard way: these are so-called system applications that are built into the firmware by the manufacturer, which include Google services, Mi browser, themes, music, videos and various analytical modules, Direct removal of such components without preparation can disrupt the system.
To start, disable the app. Instead of the uninstall button, the program control menu can have a Disconnect button, and once you click it will stop running, updating, and consuming resources, even though it will physically remain in memory, a safe method for services like Google Movies, Google Music, or Mi Credit if you don't use them.
If the disable button is also not available, special tools will be required. One popular method is to use the ADB AppControl utility on the PC or similar applications on the smartphone itself, requiring the activation of the debugging mode over USB. The developer mode is activated by seven times pressing the build number in the About Phone section. After activation in the menu Additional → For developers, you need to enable the Debugging over USB.
Risks of removing system components
Using ADB for deep cleaning of the system
The most effective way to clean up Redmi 7A from built-in garbage - using the Android Debug Bridge toolkit (ADB). This method allows you to remove even those applications that are hidden from the user. To work, you will need a computer (Windows, macOS or Linux), USB-cable ADB. Connect your smartphone to your PC and allow debugging in the pop-up window on your phone screen.
Once connected, open the command prompt or terminal on your computer in the ADB folder. Enter the adb device command to make sure the device is visible. To get a list of all packages, use the command:
adb shell pm list packagesTo remove a particular application, you need to know its exact packet name (e.g. com.xiaomi.scanner for scanner).
adb shell pm uninstall -k --user 0 name packetThe --user 0 option is critical: it removes the application only for the current user without affecting the system partition. This allows you to restore the application through resetting in case of an error. Safe removal through ADB does not require root rights, which makes this method the preferred method for most users.
☑️ Check before removal through ADB
Analysis of space and hidden files
Often, when applications are removed, space is not freed up as expected, because many programs leave behind residual files, cache and logs. With Redmi 7A, with its modest storage capacity, this becomes critical. Use the built-in Security → Cleanup app for analysis, but third-party utilities like Files by Google or DiskUsage are better suited for deeper analysis.
Apps like DiskUsage visualize the file system as a graphics card, where the squares are the size of the files, and it allows you to instantly find the heavyweights: forgotten videos in messengers, cache cards, offline navigation or update logs. Often in the folder Android/data or Android/obb you can find gigabytes of data from long-distant games.
Also worth paying attention to the folder MIUI/Gallery/cloud/cache, where you can accumulate thumbnails and deleted photos, and the Tencent folder if you use messengers like WeChat or QQ. Regular cleaning of these directories helps to keep Redmi 7A in good shape.
Comparison of cleaning methods: efficiency table
To make it easier for you to choose the right way to optimize the Redmi 7A, we have prepared a comparison table that will help you assess the risks and effectiveness of each method depending on your skills and goals.
| Method | Necessary rights | Risk to the system | Efficiency |
|---|---|---|---|
| Standard removal | No. | Absent. | Low (only user-generated software) |
| Disabling applications | No. | Minimum | Medium (remains in memory) |
| ADB (User 0) | USB debugging | Medium (requires knowledge) | High (removes system software) |
| Root + System App Remover | Root rights | High (possibly "bricking") | Maximum (full control) |
As you can see from the table, for most users, the optimal balance between security and the result is the ADB method. It allows you to remove the excess without violating the integrity of the system partition completely. Root rights give full control, but on modern versions of Android and MIUI, their obtaining is difficult and can block the operation of banking applications.

Use of the ADB parameterized --user 0 —"The middle ground for cleaning Redmi 7A, allowing you to remove system software without the risk of losing the warranty or break the bootloader.
Recovery of Remote System Components
If you deleted something extra while optimizing the Redmi 7A and noticed strange behavior (no sound, no camera, no settings), don't panic. Because we used the deletion method for the current user, the data physically stayed in the system partition.
The easiest way is to reconnect to ADB and setup command:
adb shell cmd package install-existing name packetThis command will restore the application from the system storage. If you do not remember what you deleted, or the phone is unstable, a complete reset will help. Go to Settings → About the phone → Reset → Erase all data. This will return the smartphone to factory state, but delete all your personal files, so backup is mandatory.
⚠️ Warning: Before you reset, make sure that your Mi and Google account are deleted from your device or you remember the passwords from them. Otherwise, theft protection will work and the phone will be locked.
Prevention and optimization after cleaning
After successfully cleaning Redmi 7A of excess software, it's important to keep the result fixed. Android is prone to accumulating garbage over time. Set a rule: check the Download folder once a month and clear the cache of heavy apps like Telegram, WhatsApp and YouTube. These messengers tend to grow to giant sizes.
It is also recommended to limit background activity. In the battery settings, select an application and set a background activity limit. This will not only save RAM space, but also prolong battery life, which is very important for the Redmi 7A with its compact battery. Auto-run applications is also better kept under control through the application Security → Permissions → Auto-Start.
Don't install apps from questionable sources. Often, with "hacked" games or modified versions of programs, your phone is hit by malware advertising, which quietly sets shortcuts and background processes. Use only trusted stores like Google Play or GetApps.
