Modern smartphones like the Xiaomi Redmi Note 8 Pro have impressive specs, but they start to run slower over time, due to the accumulation of temporary files, residual data from remote applications and bloated system cache. Users often notice that the interface has become less responsive and games have begun to slow down.
Owners of Android devices and MIUI shells know that standard tools are sometimes not enough to clean up deep. The accumulation of digital garbage not only reduces processor performance, but also critically reduces the amount of internal memory available. In this article, we will discuss proven methods that will help return your gadget to factory speed.
Don't ignore regular maintenance, because a crowded drive can cause important applications to run in an unstable way. We'll look at both built-in tools and more advanced ways to be careful, and you'll learn which folders can be manually deleted and which ones can't be touched.
Built-in MIUI optimization tools
The first step in the battle for space should be to use the regular Security app, which, unlike its third-party counterparts, has deep access to system processes and does not require special permissions, and is able to find hidden debris that ordinary file managers can skip.
To get started, open the Security app and select the Cleanup section. The system will automatically scan the device and prompt you to delete temporary files, browser cache and update residues. Click the Clean Up button to start the deletion process.
β οΈ Warning: Before pressing the cleanup button, carefully review the file list. Sometimes the system marks as garbage important logs or messenger cache where the received but not viewed media files are stored.
Then go to the "Acceleration" section, and you'll see a list of background processes that are running, and if you click on the acceleration button, you force the applications that are consuming RAM to close, which will give you a temporary performance boost, but it won't solve the problem of space shortage.

Regular use of the built-in cleaner once a week prevents critical filling of the system partition and keeps the interface running fast.
Manual cleaning through the file manager
Automatic scanners don't always find specific debris left by specific applications. For deep cleaning, you need to go to the Explorer or Files app. Here you need to enable the display of hidden folders in the settings to see all system directories.
Pay special attention to the Android/data and Android/obb folder. It stores caches of games and heavy apps. If you delete a game but the folder with its name is still there, you can erase it, and it's also worth checking the root directory for folders with the names of remote programs.
- π DCIM: Check the.thumbnails folder, there are thumbnails of photos that can take gigabytes.
- π¬ Tencent/MicroMsg: garbage folder from WeChat and sometimes messengers associated with cache.
- π± Download: often forgotten by users, but contains old installations APK-file.
Just as important is the folder. MIUI/debug_log, If it's on your device, it resets error reports that the average user doesn't need, and removing the contents of that directory is safe and frees up a lot of space.
What to do if the folder is not deleted?
Application cache management
The most voracious consumers of memory are usually social networks and instant messengers. Telegram, Viber and Instagram store every photo and video you see in cache, even if you did not download them on purpose. Cleaning through the system settings gives a better result than a standard cleaning inside applications.
Go to Settings β Apps β All apps. Find a heavy app like YouTube on the list. Click on it, select Storage and then clear cache. It's important not to confuse this with Clear All, because the second option will delete your authorization and settings.
There is a separate built-in cleaning mechanism for Telegram messenger that works more efficiently than the system one. Go to Telegram settings, select Data and Memory β Memory Use. Here you can not only clear the cache, but also set a limit on its size, for example, 500 MB. Old files will be deleted automatically.
β οΈ Note: Clear Data will completely reset the application to the state after installation.You will lose correspondence if they are not stored in the cloud, and your account settings.
Analysis of the occupied space
Sometimes it's hard to know what's eating up memory. The built-in storage analyzer in MIUI shows the big picture, but for detailed study, it's better to use specialized utilities or careful manual analysis. Often users forget about the downloaded files in the Bluetooth or Xiaomi folder.
Use the table below to figure out which sections require regular attention and which ones are better not to touch without emergency:
| Folder/Section | Type of data | Can I remove it? | Risk |
|---|---|---|---|
| /DCIM/.thumbnails | Miniatures photo | Yes. | Low (to be recreated) |
| /Android/data | Cash app. | Partially. | Medium (resetting game settings) |
| /MIUI/Gallery/cloud | Cloud miniatures | No. | High (loss of synchronization) |
| /Download | Downloads. | Yeah (selectively) | Low. |
When analyzing, consider that system files are marked as "System" and artificially undersized in some menus. The real weight of the system partition can be hidden. If the memory fills up on its own without user input, the system log file may malfunction, which grows endlessly.

Use the Statistical or Task Manager app in the Engineering menu (code ##4636##) to see the actual activity of processes, but be careful about changing settings.
Removal of residual files and duplicates
When Android apps are removed, they often leave their configuration files and empty folders, and over time, they number in the hundreds, and although they take up little space individually, collectively, they create fragmentation of the file system, which slows down the reading of data.
To find duplicate photos, which often occur when sync failures or re-import contacts, you can use the "Find duplicates" function in the gallery or third-party light utility. By deleting copies, you free up space without losing the quality of the content.
- ποΈ Residues APK: After installing the program, the.apk installation file is no longer needed.
- π Error Logs: Files with.log extension at the root of the system.
- πΊ Streaming cache: temporary files from Netflix, YouTube that didn't automatically delete.
Some users prefer to use ADB-This requires a computer connection and drivers. Adb shell pm clear com.package.name allows you to completely clear the cache and data of a particular application remotely.
adb shell pm trim-caches 999999999This command (requires root rights or special permissions in some versions of Android) tries to trim the cache of all applications to a specified size. On the standard Redmi Note 8 Pro without root rights, it may not work, but it is useful to know about its existence.
Prevention and system setting
So, to keep from going back to cleaning every month, you have to configure the system correctly. MIUI has a memory extension feature that uses a portion of the internal storage as virtual RAM, and if you don't have enough space, you better turn it off so you don't fragment the drive.
Check the autoload of applications regularly. Many programs are written into start-up without the user's knowledge. Turn off autoruns for applications you don't use daily, which will reduce the CPU load and reduce the amount of cache you create.
βοΈ Monthly prevention Redmi Note 8 Pro
It is also recommended to disable automatic saving of screenshots to the cloud if you are not actively using this feature. Constant synchronization of large amounts of data can create temporary buffer files that take up space until the moment of successful download.
β οΈ Warning: Donβt install the dubious antivirus and accelerator apps from the Play Market.They are trash, consume battery life, and display intrusive ads, slowing down the Xiaomi Redmi Note 8 Pro.
