Owners of a popular smartphone Redmi 8 Pro often face a situation where the device, after working for some time, begins to work slower. This is due to the accumulation of temporary files that take up precious space in the internal memory. Understanding how to clear the cache on Android Redmi 8 Prois a key skill for maintaining gadget performance.
Cache memory is designed to speed up the loading of frequently used data, but over time it grows to gigantic proportions. In this article, we will analyze in detail safe methods for clearing system and user data so that your phone can “fly” again.
The concept of cache memory in the MIUI system
To properly manage the resources of your smartphone, you need to understand the difference between the types of stored data. Application cache —these are temporary files that apps create for quick access to information. For example, the browser saves images of sites, and messengers save viewed photos.
In the operating system Android with shell MIUI there are several levels of caching. There is a cache of individual apps that can be deleted without affecting your personal data. There is also a system cache, which is responsible for the operation of the interface and service processes.
⚠️ Attention: Do not confuse clearing the cache with resetting data. When clearing the cache, your logins, passwords and correspondence are saved, and when you reset the data, the application returns to the “as after installation” state.
Regular cleaning helps to avoid file version conflicts when old information interferes with the correct operation of the updated software. This is especially true for social networks and navigators that actively use geolocation and media files.
The browser cache often takes up the most space if you actively watch videos or visit “heavy” sites with a lot of graphics.
Clearing the cache through the standard Security application
The easiest and safest way to free up space on Xiaomi Redmi 8 Pro — use of the built-in utility. The company Xiaomi preinstalls an application Securitythat is optimized specifically for their shell.
To start the process, you need to find an icon with a green shield on the desktop. After opening the application, the system will automatically scan. You will need to press the button Cleaning, which is usually located in the center of the screen or in the top block of memory statistics.
- 🧹 The system will find temporary files, remnants of uninstalled apps and advertising junk.
- 📊 You will see a detailed report on how many megabytes there will be released.
- ⚙️ In the scanner settings, you can select the depth of file scanning.
- 🚀 After cleaning, it is recommended to restart the device to apply the changes.
This method deletes only safe files that do not affect the performance of installed apps. However, it does not always delete the cache of specific “heavy” applications completely, so sometimes manual intervention is required.
Manually clearing the cache of specific applications
If the standard utility did not help solve the problem with lack of space, you should proceed to manual settings. This method allows you to specifically delete data from specific apps that consume the most resources.
Go to the menu Settings of your smartphone. Next, select the section Applications and click on the item All applications. In the list that appears, find the app whose cache you want to clear (for example, YouTube, Telegram or Instagram).
Inside the menu of a specific application, find the section Memory. There you will see two buttons: Clear and Delete. We need the button Clear, since it only resets the cache.
☑️ Correctly cleaning the application
⚠️ Attention: Be careful with the "Delete" or "Reset" button, as it will erase all your login settings and local data inside it applications.
By repeating this procedure for the 5-10 most active apps, you can free up several gigabytes of space. This is especially useful before installing large games or system updates.
Using developer mode for deep cleaning
For advanced users, there is a control option. cache of all applications at once through the menu for developers. This method allows you to perform a mass clearing, but requires preliminary activation of the hidden mode.
To enable the mode, go to Settings → About phone. Find the line MIUI version and quickly click on it 7-10 times in a row until the notification “You have become a developer” appears.
Now return to the main settings and find the new item Advanced (or Advanced settingsThere will be a section inside For developers. Scroll down to Cached processes or Do not save actions, however, for cleaning it is better to use the command through ADB or specialized menus, if they are available in your firmware version.
| Data type | Where it is stored | Deletion security | Impact on speed |
|---|---|---|---|
| Application cache | Internal memory | Completely safe | The first launch is slower |
| User data | Internal memory | Deleting accounts | Resetting settings |
| System cache | System partition | Safe after reboot | Optimizing OS operation |
| Dalvik files | System partition | Requires Recovery | Global rebuild |
Using developer tools gives more control, but requires care. Incorrectly changing the settings in this section can lead to unstable battery or background processes.
What is Dalvik Cache?
This is a special cache of optimized application files that is created when the system is first booted or after an update. Clearing it is possible only through Recovery Mode and takes a long time the next time. loading.
Clearing the cache through Recovery Mode
If the smartphone does not work correctly, freezes or does not boot normally, you may need to clear the cache through Recovery Mode (Recovery ModeThis method deletes temporary system files without affecting personal photos and contacts.
To enter this mode, you must completely turn off Redmi 8 Pro. Then hold down the Volume Up and Powerbuttons at the same time until the logo appears Mi, then release the power button, but continue to hold the volume.

Automation of the process and useful tips
In order not to perform manual cleaning every time the memory is full, you can set up automatic scripts. The application Security has an "Auto Cleaning" function, which can be activated in the settings.
It is also worth paying attention to the settings of the applications themselves. Many messengers, such as WhatsApp or Telegram, have their own settings for storing media files. It is recommended to disable autosaving of photos and videos to the gallery.
Check the folder Downloads (Downloads) regularly. Often, APK installation files, documents and pictures accumulate there, which are no longer needed, but take up space. Removing them does not affect the operation of the system, but frees up space.
- 📅 Set up weekly cleaning in the Security application.
- 📵 Disable auto-downloading of media in instant messengers.
- 🗑️ Regularly clean the "Downloads" folder of old files.
Following these simple rules will keep Redmi 8 Pro in excellent condition throughout its entire service life. Remember that clogged memory is the main reason why any Android smartphone slows down.
Use cloud storage for photos. This will transfer the load from the internal memory of the phone to the server, leaving only thumbnails on the device.
Frequently asked questions (FAQ)
Will my correspondence be deleted when clearing the messenger cache?

Why does the cache quickly fill up again after clearing?
This is normal system behavior. Applications again create temporary files for faster operation. If the cache grows abnormally quickly (gigabytes per day), there may be an error in the application, and you should try updating it or reinstalling it.
Is it possible to delete the Android folder completely?

Do you need to reboot the phone after each wipe?
After cleaning through the Security application, a reboot is not necessary, but is advisable to completely free up RAM. After cleaning via Recovery Mode, rebooting is a mandatory step in completing the procedure.
