Owners of the Xiaomi Redmi 8 will inevitably experience slowdowns over time, a natural process of accumulating temporary files that apps create to speed up access to data, but over time, this cache grows, taking up precious space in internal memory and sometimes causing malfunctions in programs.
Cleaning temporary files is not just a way to free up a few megabytes, but it is also an effective way to solve many software errors. If your favorite application stops running or freezes at launch, it is the removal of accumulated debris that often becomes a salvation.
In this article, we will take a look at all the cleaning methods available, from standard system tools to advanced developer tools, learn how to safely delete unnecessary data without affecting important information, and understand how to keep Android in optimal condition.
The concept of cache and its impact on the work of Redmi 8
Cache is a buffer memory that stores temporary data for quick access. When you open an application for the first time, the system downloads resources, but when you re-start it takes them from the cache, which allows programs to run faster and saves traffic.
But there's a downside to this, because cache files can get corrupted or conflict with new app updates, and in these cases, cleaning the cache becomes a necessary procedure to restore the device to normal operation.
On the Xiaomi Redmi 8, which is powered by a Snapdragon 439 processor, free space in internal memory is critical. A crowded data section could cause the phone to start running noticeably slower and new apps to stop being installed.
⚠️ Cache cleaning does not delete your personal photos, contacts or passwords. It is a secure procedure that affects only temporary application files.
You have to distinguish between the cache of the application and the cache of the system, the first one can be cleaned selectively for each program, the second one can be cleaned globally through the recovery menu or special utilities, and understanding this difference will help you not delete the excess.
Preparation of the device before cleaning
Before you start taking action, you have to take a number of preparatory steps to keep your data safe and ensure that the process goes smoothly, and while the risk of losing information is minimal, you should not neglect the basic precaution.
First of all, make sure that the battery is at least 30-40%.Sharp power surges or turn off the phone during system operations can cause damage to the file system.
☑️ Ready for cleaning
It is also recommended to close all running applications, which will allow the system to correctly determine the amount of memory used and free up resources for maintenance, open the menu of running tasks and press the cleanup button.
If you plan to use third-party utilities for deep cleaning, check their rankings in Google Play beforehand.
Cleaning the cache through Xiaomi settings
The easiest and safest way is to use the built-in Security app, which is integrated deep into the MIUI shell and allows you to remove garbage without risking damaging important files.
Find a shield and lightning icon on your desktop, launch the app and wait for the automatic scan to finish, and the system will determine the amount of junk files it has.
Click on the "Clean" button to delete temporary files found. This method removes general system debris, but does not affect the cache of specific applications unless you go to the appropriate section.
For more detailed work, go to the Cleanup section inside the app, where you'll see categories like "Recent," "Large Files," "Applications." When you select the "Applications" category, you can see how much space each program's cache takes up.
💡
Use the “Accelerate” function in the Security app regularly to prevent a large number of temporary files from accumulating.
It's important to note that an integrated cleaner can sometimes be too aggressive or can pass some types of garbage, so it's helpful to know alternative methods.
Removing the cache of individual applications
If you only have one problem, like YouTube or Instagram, it doesn't make sense to clean the entire phone.
To do this, go to the Settings menu, then select the Apps section and find All Apps. In the list, find the problem program.
Click on it and select Memory (or "Storage"), and you'll see two buttons: Clear cache and Clear everything. One deletes temporary files, the other resets the app to factory settings, removing logins and data.
| Type of cleaning | What's removed | Impact on data | When to use |
|---|---|---|---|
| Clear the cache | Temporary files, thumbnails | Data saved | In short of space |
| Clear it all up. | Cash, settings, accounts. | Total reset | For errors of entry |
| Delete the appendix | All program files | Program removed | If you don't need a program |
| Stop it. | Processes in memory | Temporarily | When you're hanging. |
Use the "Clear All" button only in extreme cases when the application is not working properly even after reinstalling or clearing the cache, remember that after that you will have to re-enter passwords.
On Redmi 8, application memory management works stably, but if the “Clear Cache” button is inactive (gray), then temporary files do not take up space or are absent for this application.
Cleaning through the Recovery menu (Recovery Mode)
For deeper cleaning that affects the system partition, you can use the Recovery menu, which removes temporary system update files and other system logs.
To get into this menu, turn off the phone completely. Then press the Volume Up button and the Power button at the same time. Hold them until the Mi logo appears, then release the power button, while keeping the volume high.
In the menu that appears, the navigation is done with volume buttons (up/down), and the choice is confirmed by the power button.
⚠️ Warning: Don't confuse Wipe Cache Partition with Wipe Data! The second option will completely delete all your files and return the phone to factory state.
Once you have selected the confirmation command, the system will begin the cleaning process, which can take from a few seconds to a minute. Once completed, select Reboot.
This method is especially useful after major updates to the Android operating system or the MIUI shell, when old system files may conflict with new ones.
What to do if the Recovery menu does not open?
Using third-party cleaning applications
If built-in tools are not enough, you can turn to time-tested utilities, Files by Google is considered the leader in this area, which is often pre-installed or easily downloaded from the store.
This app analyzes memory and suggests removing duplicate files, old screenshots and app cache, and it works gently and doesn't delete anything without your confirmation.
Another popular option is SD Maid, which is a more professional tool that can find files left over from remote applications, and basic functionality is enough for the average user.
Avoid installing accelerators and antiviruses from unknown Chinese developers who promise incredible 200% acceleration, often using more resources than they save, and displaying intrusive advertising.
💡
The best cleaner is the built-in Security app in conjunction with manually removing the cache of heavy applications.
Memory overflow prevention on Redmi 8
To avoid having to constantly clean the phone, it is worth sticking to simple rules of operation. Xiaomi Redmi 8 has a modest amount of internal memory (32 or 64 GB), so saving space here is relevant.
Check the download folder regularly. PDF-files, installation packages APK And the pictures from messengers that you no longer need.
Set up automatic cleaning in messengers. Telegram and WhatsApp can set a limit on the shelf life of media files in the cache, for example, delete photos and videos older than 3 days.
Use cloud storage for photos and videos. Services like Google Photos allow you to free up space on your device in one click, saving originals in the cloud.
⚠️ Warning: Don't fill your phone's internal memory with a "tidy-up"; Android should always be free at the minimum to function properly. 10-15% total.
Following these simple tips will allow your Redmi 8 to run fast and stable throughout its lifespan, avoiding a critical system slowdown.
