Xiaomi’s Redmi series is popular for its value for money, but even budget models can slow down over time, often due to the accumulation of temporary files that the system and applications create for quick operation but forget to delete. Redmi 9A users often face a lack of internal memory and slowdown of the interface, which is solved by regular cleaning of the cache.
Temporary files, or cache, take up precious storage space, which budget devices usually don't have much. If you don't do periodic cleaning, the system can start to work unstable, and applications can fly out or open for a long time. It's important to understand the difference between clearing a cache and a complete reset so you don't lose important data, such as contacts or photos.
In this article, we will take a closer look at all the available ways to clean up temporary data on Xiaomi Redmi 9A. We will look at both standard MIUI shell tools and deeper methods through application settings. Cache deletion does not affect your personal files, logins and passwords, so the procedure is completely secure for user data. Follow the instructions to return the smartphone to its previous speed.
Why you need to clean the cache on Redmi 9A
Cache is a set of temporary data that applications store on the device to speed up their work, for example, the browser saves copies of visited pages, and social networks save images from the tape, so as not to download them each time, over time, the volume of such files can reach several gigabytes, which is critical for the Redmi 9A with its limited amount of internal memory.
When space runs out, the Android operating system starts to run slower because it lacks the resources to write new temporary files, which leads to friezes, long downloads and even forced shutdowns. Regularly cleaning temporary files helps to free up space and restore the normal speed of the device.
But remember, the cache is for speed, and if you delete it completely, the applications will run a little slower when they first start up until they create new temporary files again, so you don't have to fanatically clean the cache every hour, do it once a week or when there are obvious signs of memory shortages.
Use of the built-in "Security" application
The easiest and safest way to clear the cache on the Xiaomi Redmi 9A is to use a standard system tool. The MIUI shell preinstalled the Security app, which combines antivirus and memory cleaner, which is ideal for ordinary users, since it eliminates the risk of deleting important system files.
To start, you need to find an icon on your desktop or in the Tools folder called Security and a green shield. Once you start the application, select the Cleanup function. The system will automatically scan the device for junk files, including app cache, remnants of deleted programs and advertising files.
Once the scan is complete, the amount of debris found will appear on the screen, and by clicking the "Clean" button, you delete all the temporary files found, and the process takes a few seconds and requires no additional confirmation for each file, which makes it very convenient.
☑️ Checking before cleaning
It’s worth noting that the built-in cleaner is sometimes too conservative and doesn’t remove the cache of some heavy apps like Telegram or Instagram. In such cases, a deeper cleanup is required through the specific app settings, which we’ll talk about in the next sections.
💡
Use the cleaning widget on your desktop for quick access to the garbage removal feature without running the full app.
Clearing the cache of individual applications through settings
Some applications, especially instant messengers and social networks, accumulate a huge amount of data that a standard cleaner may miss or be afraid to delete, in such a case, manual cleaning through the application management menu, which allows you to free up a significant amount of space without deleting correspondence and accounts.
To do this, go to the Settings menu of your Xiaomi Redmi 9A. Next, select the App section and click on All Apps. In the list that opens, find the desired application, such as YouTube or Viber, and click on it to go to the control menu.
Inside the app menu, you'll see the Memory button or the amount of space you're taking, and you'll click on it and you'll see the separation between "Application Memory" and "Cash." You need the Clear button in the "Cash" section, and it's important not to confuse it with the "Clean All" or "Delete" button, because that will result in the application being completely reset to a factory state with loss of data.
⚠️ Note: When you clear the cache through the app settings, you will not lose your accounts and correspondence, but you may need to re-authorize in some services.
By repeating this procedure for the 5-10 heaviest applications, you can free up a few gigabytes of memory, especially for models with 32 GB of internal memory, where every gigabyte counts, and regular checks of heavyweights will help keep the system in good shape.
Delete temporary files through Storage Settings
Newer versions of MIUI and Android have easy access to memory management through general system settings, which allows you to visually assess what exactly occupies space on your Redmi 9A and remove the batch cache without going to each application separately.
Go to Settings → Phone → Memory (or Storage) and analyze the file allocation and suggest that you clean up the garbage. Often you see a category called "Other" or "System Data" that inflates with the cache, and clicking on the cleanup button in this menu will trigger a deeper scan than in a standard security application.
And you can see the details by file type, images, videos, documents and applications, and if the cache takes up too much space, the system will prompt you to clear it, and it's a convenient way to comprehensively diagnose the memory status of the device.
| Type of data | Description | Can I remove it? |
|---|---|---|
| Cash app. | Temporary files to speed up work | Yes, it's safe. |
| Residual files | Fragments of remote programs | Yes, it's safe. |
| Application memory | Account data and settings | No, you'll lose the entrance. |
| System files | Files of Android and MIUI | No, it's possible. |
Using this settings section gives you a better idea of where the space is going, and unlike quick cleaning, here you see the pattern of memory consumption, which helps you plan for future actions to free up space.
Why does memory fill up again?
Deep cleaning in the application "Conductor"
Xiaomi’s standard file manager, known as “Conductor,” has hidden features for finding junk files. Although it’s primarily designed to navigate through folders, it has a dedicated cleanup section that users often ignore.
Open Explorer, and at the top of the screen you'll see the Garbage category. When you click on it, you'll start the scan, and the peculiarity of this method is that it often finds files that the Security app lets through, such as browser download remnants or temporary update files.
After analysis, the system will suggest that you delete what you found. Be careful: unlike automatic cleaning, you may sometimes find files you would like to save (for example, unfinished downloads).
The good thing about this method is that it works at the file system level, not just through the application API, which allows you to clean up deeper deposits of temporary debris accumulated over the months of using the Xiaomi Redmi 9A.
Cleaning the cache in Recovery mode (for advanced)
For power users, there is a way to clean the system cache through the Recovery Mode menu, which removes temporary files from the operating system itself that can accumulate after updates or crashes, a more radical method than cleaning through settings.
To get into the Recovery menu on Redmi 9A, you need to turn off the phone completely, then press the Volume Up and Power buttons simultaneously, hold them until the Mi logo appears, after which the phone goes to the main Recovery menu, and the volume buttons control the phone, and the power button selects.
From the menu, select Wipe Data and then Wipe Cache. It's important not to confuse it with Wipe All Data, which will completely reset the phone to factory settings with the loss of all photos and contacts. After cleaning the cache, select Back to Main Menu and then Reboot.
⚠️ Note: Entering Recovery mode and manipulating system partitions requires caution. If you are not sure about your actions, it is better to use software cleaning methods through the settings menu described above.
This method is recommended only in cases where the phone is not working properly after the system update or if standard methods are not working.
💡
Recovery Mode is a powerful tool for cleaning the system cache, but only use it when you have serious performance issues or after major software updates.
