How to Clean Xiaomi Redmi 9A Phone From Garbage: The Complete Guide

Xiaomi’s Redmi series is well-deservedly popular for its excellent price-performance ratio, but over time, even a powerful device can start to work slower. The main reason for the decline in performance is the accumulation of system debris, residual files from remote applications and sprawling cache. The owner of Redmi 9A may notice that the interface has become delayed, and free space in storage is rapidly disappearing for no apparent reason.

Regular cleaning not only frees up precious gigabytes for your photos and documents, but also extends battery life by reducing the load on the processor. Android, which runs the MIUI shell, has built-in maintenance mechanisms, but often requires manual intervention for deep cleaning. Let's take a look at proven ways to get your device back to speed.

Memory Occupancy Analysis and Hidden Files Search

Before you start deleting data, you need to understand what exactly takes up space. Owners of Redmi 9A often face a shortage of internal memory, since budget models often have a limited amount of storage. The system can show that memory is occupied, but not specify which folders have swelled to giant sizes.

For a detailed analysis, you go to the settings menu and select About Phone, and then click on Warehouse. Here you will see a color diagram showing the distribution of data. Visualization helps quickly identify the "eaters" of space, which are often instant messengers or streaming services.

Particular attention should be paid to folders with media files from social networks. Telegram and WhatsApp tend to save all the videos and images viewed in the gallery, dubbing them into cache, which creates a “snowball” effect, when several gigabytes are filled unnoticed by the user.

• 📱 Check the “Other” section in the repository – there are often hidden remnants of remote programs.
• 📸 Analyze the folder. DCIM — Sometimes there are videos that you copied to your computer a long time ago.
• 💬 Study attachments in messengers – they occupy up to 40% of the space of active users.

⚠️ Note: Do not delete files from Android system folders, MIUI Deleting critical system files can lead to unstable interfaces or loss of application data.

Use of the built-in "Security" application

The MIUI shell differs from pure Android by having a powerful built-in optimization tool. The Redmi 9A desktop always has an app called Security (a green shield icon) that is not just an antivirus, but a comprehensive system maintenance combiner that knows the structure of files better than third-party programs.

When you run the app, you'll see a "Clean Up" button. Once clicked, the system will scan and suggest that you delete temporary files, remnants of APK installers and advertising debris. The process takes only a few seconds and is safe for user data.

However, standard cleaning is often superficial. For a deeper analysis, click on the Garbage icon inside the app and wait for the re-scan to be completed. The system will find files that have not been deleted for more than 30 days and prompt them to clean up.

💡

Run the “Accelerate” function in the Security app before cleaning the memory – this will free up RAM and allow the scanner to work faster.

It is important to update the virus databases and garbage definitions within this application regularly, and to do this, go to the Security settings (three dots in the corner) and select Update. Current databases allow you to find new types of adware that can masquerade as system processes.

Manual cleaning of app and browser cache

The biggest amount of temporary data is accumulated by browsers and social networks. When you view the news feed on VK, Instagram or YouTube, the phone stores thumbnails of images and snippets of videos in cache so that when you reopen the page loads faster, over time this cache can grow to several gigabytes.

To clear the cache of a particular application, go to Settings → Apps → All apps. Select the desired program from a list, such as Chrome or Google. In the menu that opens, find Memory or Storage and click Clear Cache.

Be careful: there is a difference between Clear Cache and Clear Everything. The first button only deletes temporary files, the second button resets the application to the state immediately after installation, deleting your logins, settings and stored data. For regular cleaning, only use cache cleaning.

Don’t forget the built-in Mi Browser or Chrome browser. Inside the browser settings, there is a separate Privacy or History section where you can choose to delete cookies and cache, which is especially useful if pages on the Internet are not displayed correctly or the site requires re-authorization.

Removal of duplicates and large files

When you use a smartphone, you often create copies of files, for example, you could download an image from the Internet, save it to a gallery, and then send it to the messenger, creating another copy. On Redmi 9A, with its limited memory, such duplicates are critical.

The MIUI file manager can find the same files, open the Explorer app, go to Documents or search. Often duplicates are found in Download download folders and WhatsApp/Media attachments.

You should also look at large files that you might have forgotten existed, whether it's old movies, tape recorders, or archives, and deleting one file can free up more space than cleaning up hundreds of small text documents.

⚠️ Warning: Before you delete files from the Download folder, carefully check their contents. There may be important checks, tickets, saved passwords or work documents that are not stored anywhere else.

Cleaning messengers: Telegram and WhatsApp

The leaders in memory consumption on any Android smartphone are messengers. Telegram and WhatsApp store all media files in the memory of the device by default. If you are in a lot of chats and channels, your Redmi 9A can be filled with unnecessary pictures and videos.

Telegram handles the situation in the most elegant way possible: Go to Settings → Data and memory → Memory Use. Here you can click the "Clear Cache" button. The main advantage of Telegram is that when you delete the cache, your correspondence does not disappear — media files are simply deleted from the device, but remain on the server, if necessary, you can view and download them again.

WhatsApp has a different approach. There's no cloud cache in the same sense. To clean up junk files, open a chat, click on the contact name on top and select Media, links and documents. Then choose Free or Size, which will remove heavy videos that have been sent repeatedly.

• 🗑 In Telegram, enable autodelete the cache (for example, store 3 days).
• 🚫 On WhatsApp, turn off auto-save to the gallery in chat settings.
• 📂 Regularly check the tab "Documents" in messengers - there are often heavy PDF archives.

It is also recommended to disable automatic download of media on the mobile network, which will not only save space, but also save your traffic, set up autoload only for Wi-Fi or turn it off completely for video files.

Removing unused applications and system debris

Often, there are apps on your smartphone that you haven't used in months. They may not consume much space on their own, but their background processes and accumulated data slow down the system. On the Redmi 9A, every megabyte of RAM counts.

Do an installed app audit. Go to Settings → Apps and sort the list by frequency of use or size. If you see a game you haven't played in six months or a delivery service you don't use, delete it without regret.

Special attention should be paid to pre-installed applications (bloatware) on global versions of MIUI, they are few, but they are. Some of them can be removed, others can only be disabled, the disabled application ceases to update and work in the background, no longer being a “junk” for the system.

💡

Deleting even one heavy but unused application (such as a navigator or game) can give you more speed gains than cleaning up hundreds of small temporary files.

It's also worth checking the list of services running. Sometimes the "junk" is the hanging processes that don't close. Rebooting your phone every few days is the best way to reset these processes and clear up RAM without using third-party "task killers" who consume resources themselves.
