How to effectively clean the cache on Xiaomi Redmi 9A

Owners of budget smartphones like the Xiaomi Redmi 9A often experience a slowdown after months of heavy use, a phenomenon that is caused by overflowing internal storage with temporary files that accumulate as they use apps and web browsers, data known as cache that is designed to speed up the loading of frequently visited pages and launch programs, but over time, the excess begins to slow down the system.

Cache cleaning is a safe and necessary procedure that does not delete your personal photos, contacts or correspondence. However, it is important to understand the difference between the system cache of applications and user data so that you do not accidentally lose important information. In this article, we will discuss in detail all available methods of freeing up memory on your gadget, using both built-in MIUI tools and third-party utilities.

Regular maintenance of a smartphone allows you to extend its life and maintain a high response rate of the interface. We will consider not only standard cleaning methods, but also hidden features available in the engineering menu, and discuss what actions can harm the device. Proper memory management is the key to stable operation of your Redmi 9A.

The concept of cache and its impact on the work of Redmi 9A

Cache is a region of RAM or permanent memory reserved for temporary files. When you run an application, such as a social network or messenger, the system uploads some of the data to the cache so that when you re-access it does not waste time re-downloading from the Internet or slow storage, this significantly speeds up the interface.

However, this mechanism has a downside: over time, the cache can grow to several gigabytes, taking up precious space on the disk, the volume of which in the Redmi 9A model is often limited to 32 or 64 GB. Cache overflow can cause file version conflicts, lead to errors in the operation of applications and even a complete system freeze.

There are several types of cached data, and it is important to distinguish them before cleaning. For example, the browser cache contains copies of visited pages, and the application cache contains temporary logs and thumbnails of images. The system cache is responsible for the operation of the MIUI shell itself, and cleaning it requires more care than deleting temporary user files.

• 🚀 Accelerating application launch by freeing up processor resources.
• 💾 Freeing up useful space for installing new programs or saving photos.
• 🛠 Removal of software errors caused by temporary files corruption.

It's worth noting that completely removing the cache won't make your phone magically fast if the problem lies in hardware or a critical lack of free memory.However, it's the first step in diagnosing any software failures.

Use the Cleanup feature in the standard Security app at least once a week to maintain optimal system performance.

Use of the built-in Security application

The easiest and safest way to clear the cache on Xiaomi Redmi 9A is to use the standard tool preinstalled by the manufacturer.Security application is deeply integrated into the MIUI shell and has access to all necessary system partitions, allowing you to conduct deep cleaning without the risk of deleting important data.

To get started, you need to find an icon on your desktop called "Security" or "Security," which is usually green. Once the app is launched, the home screen will display a "Cleaner" button indicating the amount of garbage that can be removed, and clicking on this button will trigger an automatic scanner that will analyze the file system.

The scanning process takes from seconds to minutes, depending on the number of applications installed and the amount of data accumulated. Once the analysis is complete, the system will suggest removing unnecessary files, including remnants of deleted applications, advertising debris and, of course, cache. You can selectively exclude certain categories of data if you do not want to delete them.

It's important to understand that standard cleaning doesn't always delete the entire cache of applications, leaving some files for quick re-starts. It's normal system behavior to balance speed and free space. However, for deep cleaning, you can use advanced settings inside the application itself.

⚠️ Note: When using the Deep Clean feature, read the file description carefully. Some of them may be saved passwords or game progression if they are classified as application data rather than just cache.

Cleaning the cache of individual applications manually

If a particular application is not working properly or takes up an unreasonable amount of space, it is advisable to clear its cache individually. This method allows you to point the problem program without affecting it!

Go to your smartphone Settings, then select the App and then All Apps. In the list that opens, find the program you want, like YouTube or Telegram, and click on it. Inside the app menu, you will see the Clean or Clear data button, which, when you click on, will give you a choice between clearing the cache and deleting all data.

When you select Clear Cache, you delete only temporary files, and if you choose Clear All or Delete Data, the app will return to state immediately after installation, requiring re-authorization and configuration, and be careful when choosing the action so that you do not lose your correspondence history or account settings.

For some system applications, the cache clean button may be inactive or hidden, and this is done to protect critical system components from accidental damage, in which case you can try to force the application to stop before cleaning, which sometimes unlocks the necessary functions.

Regularly manually checking heavy apps like instant messengers and social media helps keep the device on track, and these programs tend to accumulate huge amounts of media cache that can be safely deleted through their own settings or system menus.

Clearing cache in the browser and system services

Web browsers are among the main consumers of disk space on any smartphone. When you visit various sites, Google Chrome or the built-in Mi Browser browser store copies of pages, images and scripts. Over time, this archive can take up hundreds of megabytes, which is essential for budget models.

To clear your browser cache, open its settings, usually available through three dots in the corner of the screen, and look for the History or Privacy section, where you will have the Clear History option, where you must tick only against the Images and other files stored in the cache.

In addition to browsers, you should pay attention to system services such as Google Play Store. Often it is the accumulated data of the app store that causes errors when installing or updating programs. Clearing the Play Market cache is done through the app menu in the phone settings, similar to other programs.

There is also the concept of Dalvik Cache (or ART Cache), which is an optimized application code for faster operation of the processor. Cleaning this partition is possible only through Recovery Mode and is extremely rare, for example, after installing custom firmware or cyclic system restarts.

⚠️ Warning: Do not attempt to manually delete files from system folders through a file manager if you are not sure of their purpose. MIUI.

Use of the developer mode and special features

For more advanced users, the Xiaomi Redmi 9A provides access to developer mode, where you can manage some aspects of memory performance. Although there is no direct “clean all cache” button, you can limit background processes, which indirectly reduces the amount of garbage created.

To activate Developer Mode, you need to go to Settings → About Phone and quickly click on MIUI Version seven times. Once activation message appears, a new section will appear in the additional settings menu, "For Developers", and you can find the option "Do Not Stay Activated", but you should only turn it on for testing, as this consumes the battery.

Also available in this section is the option of forced shutdown of all background services, which can temporarily free up RAM. However, after restarting the phone, all processes will start again. ADB-commands from a computer that allow you to clear the cache of specific packets without superuser rights.

adb shell pm trim-caches 999999999

This command, executed via a computer with ADB installed, will attempt to free a specified number of bytes (in this case almost 1 TB, a maximum) of cache on the device, a powerful tool that requires connecting the phone to a PC in USB debugging mode.

💡

Use of the ADB-commands are the most efficient way to deep clean up without losing user data, but require a computer and basic command line knowledge.

Frequent questions and problems with cleaning

Many users fear that clearing the cache will delete their personal photos or contacts. This is a common misconception: cache is purely technical information necessary for speed, and it does not contain your personal documents unless the application specifically stores them in cache (which is rare and considered a bad development practice).

Another common question is how often the procedure is done: no need to clean the cache every day; the optimal frequency is once a week or if there are signs of memory shortage; too frequent cleaning can even slow down the phone, as the system will have to recreate temporary files.

If the phone continues to run slowly after cleaning the cache, it may be the wear and tear of the flash memory or the processor overheating, and in such cases, software methods may be ineffective, and more radical measures such as a complete reset should be considered.

To sum up, regular and proper cache cleaning on Xiaomi Redmi 9A is an easy way to keep your smartphone in good condition.Use built-in tools, don't be afraid to clean the cache of browsers and heavy apps, but avoid questionable optimization programs.Your phone will thank you for the increased speed of work.
