How to Clean Cache on Xiaomi Redmi 8 Pro: The Complete Guide

Xiaomi Redmi 8 Pro series smartphones are known for their excellent performance and affordable price, but over time, even the most powerful devices start to work slower. The main reason for the slowdown and lack of free memory is often accumulated app cache and system debris. This temporary file is created to speed up the launch of programs, but when overflow begins to slow down the MIUI operating system.

Owners of the Redmi Note 8 Pro and similar models often face reports of a lack of space to install updates or new games. Regular cleaning helps free up gigabytes of space and extend the life of the drive. In this article, we will discuss all safe and effective methods of deleting temporary data to make your phone fly again.

Do not ignore the system signals about memory overflow, as this can lead to unstable memory and frequent program crashes. We will consider both standard tools of Xiaomi and advanced methods for experienced users, which require caution.

Why you should clean the cache on Redmi 8 Pro

Cache is a buffer zone where temporary data is stored for quick access. When you open a browser, social networks or heavy games, the system stores some information so that the next time you run it, it does not download it again. However, over time, these files become obsolete, take up space and may contain errors that cause interface glitches.

Clearing the cache on Xiaomi Redmi 8 Pro is necessary not only to free up space, but also to solve software conflicts. For example, if an application stops opening or does not work correctly, deleting its temporary files often solves the problem without completely reinstalling, this is especially true for messengers that accumulate a huge number of media files.

⚠️ Caution: Clearing the cache is safe for your personal data, but clearing the application data will remove logins, passwords and progress in games.

Regular maintenance allows you to extend the life of the internal drive. Constantly writing and overwriting files in crowded memory wears out storage cells faster. Therefore, maintaining free space in 15-20% of the total volume is a good habit for Android smartphone owners.

Use of the built-in Security application

The easiest and safest way to free up space is to use a regular tool from Xiaomi. Security is already installed on the system and optimized for working with the MIUI shell. It scans the device for garbage files, large unnecessary documents and residual cache.

To get started, open a shortcut called "Security" on your desktop or in the Tools folder. Click on the Cleaner button, and then the system automatically analyzes the memory, and you'll see a list of files that can be deleted without harming the system, usually advertising files, empty folders, and browser cache.

But automatic mode doesn't always find anything else. For a deeper cleaning, click on the "Clean All" button and then go to the "Files" section inside the app, where you can manually select categories like "Large Files" or "Dublicates" and delete them. This helps you find forgotten videos or installation packages. APK-file.

It's important to understand that the built-in cleaner doesn't touch the cache of system processes to keep Android stable. If you want to free up space as much as possible, you'll have to use the manual methods described below. But for weekly maintenance of a regular tool, it's enough.

Manually cleaning the cache of individual applications

Social networks, messengers and browsers are the ones that generate the most garbage, and apps like Telegram, Viber or TikTok can take up several gigabytes of memory with saved thumbnails, temporary videos and avatars, and can be cleaned through the system settings menu, giving you more precise control over the process.

To do this, go to Settings β†’ Apps β†’ All Apps. In the list that opens, find the "heavy" app you want to clean. Click on it and you'll be taken to the control menu where you'll see the space you're occupying, and here you're interested in two buttons: "Clear cache" and "Clean everything."

Use the Clear Cache button to securely delete temporary files. If you click Clear All, the app will return to state immediately after installation: you will crash out of your account and all local settings will reset. For browsers, this means deleting saved passwords and history if they are not synced to the cloud.

Why is Telegram's cache so big?
Telegram messenger by default saves all the media files viewed in the phone’s memory for quick re-view. To change this, go to Telegram Settings β†’ Data and Memory β†’ Memory Use and enable auto-delete the cache after 3 days or a week.

Cleaning Hidden Folders and Residual Files

Even after you delete applications on Xiaomi Redmi 8 Pro, they often have their tails, folders with settings and temporary files, and you can find them through the built-in file manager. Open Explorer and select the category "Folders" or go to the root of internal memory.

First of all, look at the Android/data folder, which stores the data of the installed games and programs. If you deleted the game, but the folder with its name (for example, com.gameloft.android) is left, you can delete it. Also check the Download folders and MIUI/Gallery/cloud/cache folders, where thumbnails and downloaded files accumulate.

Be careful when deleting files at the root of internal memory. Some folders have names that are not related to the application brand, but are critical to the system. If you are not sure about the purpose of the file, you better search the Internet for its name before deleting.

⚠️ Warning: Never delete folders Android/obb It's completely if it contains data from games you're still playing, and it will cause you to have to re-download gigabytes of data when you start the game.

For a deeper analysis, you can use the "Storage Analyzer" function in your phone settings. Go to Settings β†’ Memory and wait for the scan to finish. The system will show a visual map of the occupied place where you can quickly find and delete the largest files occupying space on the Redmi 8 Pro.

Use the Compression feature in Explorer for rare files. If you have archives with documents that are rarely needed, you can compress them into a file. ZIP-archive, which saves up to 60% of disk space.

Cleaning the cache through Recovery mode

There is a more radical cleaning method that affects the Dalvik/ART Cache system partition, which contains optimized files of all installed applications for quick start-up, and its cleaning is useful after major MIUI system updates or if the phone has started to work unstable.

To enter Recovery mode, turn off your smartphone completely. Then press the Volume Up and Power buttons simultaneously. Hold them until the Mi logo appears, then release the power button, but keep the volume up. Opens a menu with English text, where the navigation is done with the volume buttons and the choice with the power button.

From the menu, select Wipe Data (if you want a full reset) or find the Wipe Cache option (if available in your version of Recovery). Xiaomi's standard stock Recovery often only has a full reset or Mi Account connection option, so this method is more often used when you have a custom TWRP recovery.

The sequence of actions in Recovery:


1. Turn off the phone.




2. Clutch Volume + and Nutrition.




3. Select Wipe Cache Partition (if any).




4. Confirm the action (Yes).




5. Select Reboot.

If there is no separate cache button in the standard menu, don’t experiment with Wipe Data unless you’re ready to lose all your photos and contacts. In this case, it’s better to limit yourself to software cleaning through settings. After any procedure in Recovery, the first system boot can last up to 5-10 minutes – this is a normal process of recompilating applications.

Recovery mode is designed for advanced users.If your phone is working properly, limit yourself to cleaning through the settings menu to avoid the risk of data loss.

Automation and prevention of contamination

To avoid going back to cleaning all the time, set up automatic maintenance. There's an "Acceleration" feature in the Security app that you can add to your desktop in widgets, which allows you to close the background processes and clear the RAM in one touch.

It’s also worth revising the auto-update settings on Google Play. If you have all apps updated over the mobile network enabled, temporary installer files can fill up memory quickly, and it’s recommended to install the Wi-Fi-only update.

Check Downloads regularly, and users often forget about downloaded presentations, restaurant menus, or installers that are no longer needed, deleting these files is the fastest way to get free space on the Xiaomi Redmi 8 Pro.

Can I delete the.thumbnail folder in DCIM?
Yes, the.thumbnail folder in the DCIM directory can be deleted, it stores thumbnails of your gallery photos, and once deleted, it will be recreated automatically the next time you open the gallery, but this will temporarily make room if the thumbnails are swollen due to errors.
Does the cache affect the charging speed?
The cache doesn't directly affect charging speed, but if the background processes are loading the processor because of cache errors, the phone can heat up, which will slow the charge with the thermal control system.
Do I need to clean the cache after the MIUI update?
After a major update to the MIUI shell (for example, 11 to 12), it is recommended to clear the cache through Recovery (if there is an option) or simply restart the phone several times.
How much space should you have on the Redmi 8 Pro?
For stable operation of the Android system, it is recommended to keep at least 10-15% of the total memory free. For a model with 64 GB, this is about 7-10 GB. If there is less space, the system will start to work noticeably slower.
Do third-party applications like Clean Master help?
Modern versions of Android and MIUI are great at managing memory on their own. Third-party cleaners often consume resources and show ads. Xiaomi's built-in tools are enough for a comfortable work.
