Xiaomi Redmi 9A is a popular budget device that can slow down over time due to the accumulation of temporary files. When the MIUI operating system or specific applications store data for fast download, they take up precious space in internal memory, which leads to the phone slowing down, opening programs longer, or suddenly closing them.
Regularly cleaning the cache helps to bring back the sharpness of the interface and free up gigabytes for your photos and music. Unlike a full reset, this process is safe for your personal data, such as contacts or correspondence, if done correctly. In this article, we will break down all available methods, from simple buttons on the menu to advanced tools.
Understanding how to manage memory on Android is a key skill for any gadget owner: You will learn to distinguish system debris from important files and use embedded utilities as efficiently as possible. Let's look at the main ways to optimize the operation of your device.
What is the cache and why is it filled with Redmi 9A?
Cache is a buffer memory where apps store temporary data, such as Google Chrome, which stores thumbnails of frequently visited sites, and Instagram stores the last photos viewed so that when they are reopened, they load instantly. Over time, these files can take up a significant amount of space, especially if you have a lot of heavy programs installed.
On budget models like the Redmi 9A, the amount of internal memory is often limited, so cache control becomes critical. If you do not monitor this, the system can start to work unstable, and some applications may stop running altogether due to lack of resources.
⚠️ Caution: Clearing the cache does not delete your logins, passwords, or saves in games. However, cleaning the application data (not to be confused with cache) will return the program to a post-installing state by removing all your history inside it.
There are two main types of cache: system cache (MIUI shell itself) and user cache (individual application cache), both of which ensure the stability of the operating system, and it is important to understand the difference between temporary files and important documents so that you do not accidentally delete the information you need.
Use of the built-in "Security" application
The easiest and safest way to clean the cache on Xiaomi Redmi 9A is to use the manufacturer’s regular utility. The MIUI shell already has a Security app preinstalled, which automatically scans the device for junk files, analyzes the folder structure and identifies items that can be removed without harming the system.
To start the process, you need to find an icon on your desktop with a green shield or the signature "Security". Once you open the program, the system will prompt you to click the "Clean" button or start a scan. The utility will quickly scan the memory and show the amount of files available for removal.
☑️ Cleaning Algorithm Through Security
Once you've finished scanning, you'll see a list of categories that take up space, where you can selectively delete browser cache, ad files, or remnants of remote programs, and it's a great tool for rapid prevention that doesn't require deep knowledge in an Android device.
Manually cleaning the cache of individual applications
Sometimes, automated scanners can’t handle a particular “heavy” application that has swelled to an incredible size, and in such cases, you have to manually go into the settings of a particular service and clean its storage, which is especially true for instant messengers like Telegram or WhatsApp, which can accumulate gigabytes of media files.
To do this, go to the Settings menu, then select the App section and click All Apps. In the list that opens, find the program you want (like YouTube or TikTok). Inside the app menu, you are interested in "Memory" or "Storage".
| Action. | What's going on? | Security of data |
|---|---|---|
| Clearing the cache | Deletes temporary files and thumbnails | Secure, data is stored |
| Clearing the data | Resets the application to factory state | Data within the application is deleted |
| Stopping. | Forcedly closes the trial | Safe, the process will start again. |
On the memory management screen, you'll see two buttons: Clear cache and Clear (or Clear all data) click only on the first button if you want to just free up space. The second button will reset the app's settings completely, which may require you to log in again.
⚠️ Before clearing the data of messengers, be sure to back up your correspondence in the cloud, otherwise you risk losing the entire message history.
Why is the app's cache growing so fast?
Cleaning through the Recovery Mode menu
If the phone is not working properly, freezes or you can’t get into the settings menu, you can use Recovery Mode, which allows you to clear the system cache (Dalvik/ART cache), which is responsible for the operation of the operating system itself, a deeper cleanup than just deleting files through settings.
To enter this mode on Redmi 9A, you need to turn the device off completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power button, but keep the volume down until the Recovery menu appears.
Volume + Nutrition → Mi Logo → Let go of Meals → Wait for the Recovery MenuIn the menu, the navigation is done with volume buttons (up/down), and the choice is confirmed by the power button. You need to find the Wipe Data item, then select Wipe Cache (not to be confused with Wipe All Data, which will lead to a complete reset!). Once confirmed, the system will clear the system temporary files.
💡
If the Recovery menu does not have a separate Wipe Cache item, but only Wipe All Data, it is better to refrain from this method, so as not to accidentally lose personal files. MIUI This point is sometimes hidden.
This method is useful when installing updates or after a system crash, it helps to eliminate conflicts between old system files and the new firmware version, but for daily use, software methods through settings are better suited.
Removing browser cache and debris from downloads
Browsers are among the main consumers of free memory: Google Chrome, MI Browser or Opera store copies of the pages visited to speed up their reloading. Over time, this "baggage" becomes unnecessary, especially if you rarely visit the same sites.
To clean your browser, open it, click three dots in the corner of the screen and select Settings. Next, look for the Privacy or History section, and it will have the option to "Clear History" or "Delete Viewing Data." Make sure you tick "Images and other files saved in cache."
Also, remember the Downloads folder, and often users download APK installation files, PDF documents, or images that are no longer needed, and these files are not automatically deleted and take up dead weight, and go through this folder through the file manager and delete the extra.
Cleaning your browser regularly not only frees up space, but also increases privacy by removing traces of your online presence, especially if the phone is used by multiple people or could fall into the wrong hands.
💡
Comprehensive approach: combine automatic cleaning through the Safety app with manual cleaning of heavy messengers once a month for maximum performance.
Automation and additional tools
For those who want to forget about manual cleaning, there are ways to automate the process. Redmi 9A has an Advanced Cleanup feature that can work in the background, and you can set up memory fill notifications to remind the system to clean up.
Many users install third-party clinch apps, such as CCleaner or Files by Google, which provide a more detailed analysis of what takes up space and allow you to delete duplicate photos or large forgotten files. However, beware: too aggressive clinchers can delete the desired data or show intrusive advertising.
It's important to keep a balance. You don't have to fanatically clean the cache every day. Modern Android systems manage memory efficiently, and constant cleaning can even slow down as applications will have to recreate temporary files. The optimal frequency is once every 1-2 weeks or when there are signs of space shortage.
⚠️ Warning: Avoid installing questionable accelerator apps RAM" They're often the source of advertising and brakes, and their actual use on modern versions of Android is minimal.
