Xiaomi Redmi 8A has proven to be a reliable budget device, but its basic modification often comes with just 32 GB or 64 GB of internal storage. Over time, the MIUI operating system grows, overgrown with cache, logs and temporary files, which inevitably leads to a lack of free space. When the storage is full, the device begins to work slower, applications fly out, and new programs stop installing, requiring immediate user intervention.
In this article, we will explore not only standard cleaning methods, but also hidden system functions that will help return performance to your gadget. You will learn how to safely delete unnecessary data, transfer media files and control the processes that devour precious megabytes. Regular maintenance is the key to a long life of your smartphone without having to buy a new model.
Storage occupancy analysis and system settings
Before you start taking drastic measures, you need to understand what exactly occupies space in the memory of your Redmi 8A. Android provides built-in tools for data visualization, allowing you to identify “eaters” of space. Often it turns out that half of the memory is not the apps, but the cache of messengers and saved attachments.
To start your diagnosis, go to Settings and look for About Phone, then select Memory, and here you can see the approximate distribution of how much space apps, images, videos, audio files, etc. Take, and you can see in detail where you're going, like deleting old photos or cleaning up your social media cache.
Note the "Other" section, which is often where residual files of remote programs or system logs are hidden, which can be safely deleted. If this partition takes up a disproportionately large volume (more than 10-15 GB), it is worth doing a deeper cleaning through the file manager or specialized utilities.
Don't ignore the space shortage notifications that MIUI periodically issues. The system itself suggests starting the cleanup, but it's better to manually control this process so that important documents are not accidentally deleted. Memory control should become a habit, especially if you're actively using multimedia.
Use of the built-in "Security" application
Each Xiaomi smartphone has a security system app preinstalled, which includes a powerful garbage cleaner, and is the easiest and safest way to quickly free up a few gigabytes of space without the risk of damaging system files. Algorithms of the application are sharpened precisely under the shell MIUI.
Launch the app and press the big green Clean up button. The scanner will analyze the system for temporary files, remnants of deleted apps and ad cache. After scanning, you'll see a list of files that can be deleted. Click Clear to complete the process.
⚠️ Note: Before final deletion, carefully review the list of files in the "Large Files" or "Dublicates" section so that important documents or personal photos are not accidentally erased.
Inside the app, there's also Deep Clean, which allows you to find old APK installation packages, large files, and unused applications. Deep cleaning is especially useful when the standard method is no longer working. Regular use of this tool helps keep the phone on top.
💡
Start the built-in cleaning at least once a week so that the cache does not have time to accumulate to critical values and slow down the system.
Cleaning the cache of messengers and social networks
The most active memory consumers on any Android smartphone, including the Redmi 8A, are instant messengers like WhatsApp, Telegram, Viber and social networks, which store every picture, video and voice message viewed in the device’s memory, creating huge archives of data.
In Telegram, for example, you can set up automatic cache cleanup. Go to Settings → Data and memory → Memory Use. Here you will see the amount of cache you have occupied and you can set a self-deleting timer for, say, 3 days or a week, which automates the process and saves you time.
On WhatsApp, the situation is similar: go to Settings → Data and Storage → Storage Management. The app will show which chats take up the most space. You can selectively delete media from specific dialogues without deleting the correspondence itself. This allows you to save text history, but remove heavy videos.
☑️ Cleaning messengers
Social networks like VK or Facebook also cache feeds and videos. These apps often have a "Clear Cache" option in their settings. If you don't, you can use Android's system settings: Settings → Apps → Select App → Storage → Clear Cache. It's important not to confuse it with the "Clear Data" button, as this will remove the authorization and settings of the application.
Working with files, duplicates and hidden garbage
The Android file system is becoming increasingly duplicated with photos, empty folders and residual files after deleting games, and it’s convenient to use built-in Explorer or download a third-party file manager like Files by Google to help you find the same files that might have been saved if you crashed or rebooted.
You should pay special attention to the Download folder. Browsers and instant messengers often save all downloaded documents, installers and pictures. Check this directory and delete everything you don't need. It's also worth checking out the DCIM/.thumbnails folder, where you store thumbnails of your photos. With a lot of photos, this folder can grow to several gigabytes.
| File type | Where to find | Can I remove it? | Risk |
|---|---|---|---|
| Cash app. | Settings → Applications | Yes. | Low (the app will download the data again) |
| Files.thumbnails | DCIM/.thumbnails | Yes. | Low (the gallery will create them again) |
| APK installers | Download folder | Yes. | Not (if the app has already been installed) |
| Logs of the system | Log folder or MIUI/debug_log | Yes. | No (technical data) |
Removing duplicates is a safe operation, but always check the contents of folders before a mass cleaning. Backing up important data before such procedures is never a superfluous step.
How do I find hidden folders?
Transfer data to memory card and cloud
Xiaomi Redmi 8A supports microSD card installation, which is a great solution to space shortage, and you can transfer photos, videos, music and documents to the memory, freeing up internal memory for the system and applications.
Use Explorer to transfer files. Select the files or folders you want, click More → Move and point the way to yours. SD-Some applications, like Camera or Recorder, allow you to immediately save new files to the memory card. Go to the settings of these applications and change the default save path.
An alternative to a physical map is cloud storage, services like Google Photos, Yandex.Disk or Google Drive allow you to upload media files to the Internet and delete them from your phone, and the Free Space feature in Google Photos automatically removes from your device those images that have already been successfully uploaded to the cloud.
⚠️ Note: When transferring data to a memory card, make sure that it is high-quality and has a high recording speed (class 10 and above), otherwise recording video in the memory card. 4K Quick shooting of series of photos can work with errors.
Using cloud technology requires a stable Wi-Fi connection to avoid wasting mobile traffic. Hybrid storage (part on the phone, part in the cloud) is the modern standard for smartphone use.
Removing Unused Applications and Optimizing System
The Redmi 8A, like any Xiaomi, has a lot of apps that you don't have to use, some that you can uninstall completely, some that you can only disable, and not only does it free up space, but it also reduces the workload on the processor and RAM.
Go to Settings → Apps → All Apps. Go through the list and find programs that you haven’t used in the last few months. If the Remove button is active, delete it. If only the Disable button is available, it’s a system application that could disrupt the firmware.
Also worth checking is the boot list. Many apps run with your phone and hang in the background, consuming resources. Turn off auto-run for those programs that don't need to run all the time (such as online stores or games). → Permits → Auto-start.
💡
Removing unused apps and turning them off auto-start is the most effective way to speed up a budget smartphone, beyond physically cleaning up memory.
Regular auditing of installed software helps keep the system clean, and if you installed a game, passed it and forgot it, delete it immediately, as modern games can take up several gigabytes of space.
Radical measures: reset to factory settings
If none of the above methods helped to free up enough space, or if the system is unstable due to accumulated software debris, the last measure is a complete reset to the factory settings (Hard Reset), which will return the phone to the state “out of the box”.
Before performing this procedure, be sure to back up all important contacts, photos and documents, as all user data will be deleted in the process. Go to Settings → About Phone → Settings Reset → Erase all data.
Once reset, the phone will work as fast as possible, as there will be no fragmented files and software conflicts in memory. However, if you do not change your usage habits, the problem of space shortage may soon return, so after resetting, it is recommended to immediately configure synchronization with the cloud and prevent autoloading of excess software.
⚠️ Warning: Make sure the battery is at least 50-60% interruption of the process by turning off the phone can cause damage to system partitions and inability to boot.
