Redmi and Xiaomi smartphones are famous for their powerful hardware for an affordable price, but even the most powerful Snapdragon or MediaTek processor will not save you from the brakes if the internal memory is clogged with digital garbage. Over time, the MIUI operating system accumulates gigabytes of cached data, residual files of remote applications and time logs that do not carry any benefit but occupy valuable space. Users often notice that the phone is starting to work slower, and notifications of space shortage appear more often, although photos and videos have long been transferred to the cloud.
Cleaning up that data is not just a way to make room, it's a necessary procedure for the device to work smoothly. Unlike other manufacturers, Xiaomi has implemented aggressive memory algorithms that sometimes require manual intervention. If you want to get your gadget back sharp and get rid of annoying warnings, you need to understand the structure of the files and understand what can be deleted without risking your smartphone.
In this guide, we will go through all the cleaning techniques in detail, from built-in tools to manually deleting through the file manager. We will look at the nuances of working with social media cache, which often grows to giant sizes, and explain why standard cleaning is not always effective. Proper management of temporary files will extend the life of your device and ensure its performance for many months.
Memory Filling Analysis and Search for Hidden Eaters
Before you take drastic action to remove data, you need to do a thorough diagnostic of the storage. The Android system on the MIUI shell has built-in analytics, but they don't always show the full picture. Often, the "Other" category takes up the lion's share of memory, and the standard cleaner is powerless to explain what's in there. You need to look at the storage settings yourself to identify the main sources of garbage.
The most voracious are usually messengers and social networks. Telegram, WhatsApp and Viber store every image, video and voice message viewed into local memory, creating duplicates and temporary copies. Even if you delete the correspondence in the application, files can remain in system folders. Memory analysis allows you to see the real amount of data occupied by each application and decide whether to clean it further.
β οΈ Note: Before deleting large amounts of data, make sure that important files are stored in the cloud or on your computer. System files with the.apk or.obb extension can only be deleted if you are sure that they are related to remote games.
For a detailed analysis, use the built-in Security app, which scans the device and sorts files by type, but for a deeper dive, you'd better use third-party visualization utilities that show the memory card as graphical blocks, which will help you find forgotten downloads, old backups and error logs that can take hundreds of megabytes.
Use of the built-in "Security" application
The easiest and safest way to delete temporary files on Xiaomi Redmi is to use a regular tool from developers. Security is preinstalled on all devices and has access to system partitions closed to ordinary file managers. Run it and select Cleanup. The system will automatically scan the device and prompt you to delete the cache, advertising files and remnants of remote applications.
After the initial scan, click the clean button. However, the process doesn't end there. Scroll down to the "Recommendations" or "Deep Clean" section. Here, MIUI can suggest removing large files, duplicate photos or unused applications. Beware: the algorithm may mark important documents as junk if they have a specific format, so always check the content before confirming.
- π± Application cache: Temporary data that speeds up program launches but inflates over time.
- π¦ APK-Files: Installation packages that often remain after updating programs through the browser.
- πΈ Screenshots and sketches: Miniatures of images that can weigh more than the originals in the gallery.
It is important to understand the difference between cache and application data. Cache clearing is secure and does not affect your logins, passwords or game progress. Data clearing resets the application to a state immediately after installation. In the Security menu, you can choose what to clean. Regular use of this tool (once a week) will prevent critical memory filling.

Manual cleaning of the cache through system settings
If the automatic cleanup didn't work, you'll have to go manually, and this method allows you to pinpoint the temporary files of a particular application that is behaving incorrectly or takes up too much space. To do this, go to the Settings menu, then select the App section and click All Apps. Here's the full list of installed software.
Find a "heavy" app like YouTube, Instagram or TikTok on the list. Go to its properties and select Memory (or Storage) and you'll see two buttons: Clear cache and Clear everything. The first button only deletes temporary files, the second button completely resets the app. Use cache clearing if the app is working properly but takes up a lot of space.
| Type of data | What's removed | Impact on the account | Recommendation |
|---|---|---|---|
| Cash. | Temporary files, sketches, logs | It doesn't affect the entrance. | You can remove it regularly. |
| Application data | Settings, logins, databases | Full logout from the account | Only when there's a failure. |
| All files. | Cash + Data + In-app downloads | Complete reset to factory condition | Before reinstallation of the application |
Pay special attention to system applications such as MIUI or System Launcher, where the cleanup option may be unavailable or limited. Do not attempt to manually delete system process data through a file manager without root rights, this can lead to a cyclical reboot. If the system says that action is impossible, then the file is occupied or protected.
Why is the cache growing so fast?
Working with File Manager and Download folder
The standard MIUI Explorer (or Explorer) is a powerful tool for those who know where to look. The main dump of unnecessary files is in the Download folder. This includes documents from browsers, received files from messengers and application installers. Navigating the path Internal shared drive β Download will allow you to manually sort and delete excess.
And you also have to look at the folders of specific applications, like Telegram, which stores media files in the Telegram/Telegram Images folder or Telegram/Telegram Video folder. If you set up auto-save in the gallery, these files are duplicated. Deleting them from the file manager will free up space, but it won't delete the correspondence in the application itself. This is an effective way to delete temporary files on Xiaomi Redmi without affecting the functionality of the programs.
Look for folders called Temp, Tmp, or Cache at the root of internal memory. Although modern versions of Android restrict access to some system cache, custom apps often continue to create such directories and forget about them. Also check the Bluetooth folder, where files obtained from friends or other devices many years ago may have gotten into.
- ποΈ.thumbnails folder: A hidden thumbnail folder that can grow to gigabytes. It's at the root. DCIM.
- π Residual files: Folders with names of remote applications (for example, com.android.game) left after uninstallation.
- π Error Logs: Files with the.log extension created by malfunctioning programs.
β οΈ Note: In file manager, be extremely careful with files whose names you do not understand. Deleting system libraries or configuration files can cause some functions of the smartphone to fail.
Cleaning up garbage in popular apps (Telegram, YouTube)
Mobile Internet heavyweights deserve special attention. Telegram and YouTube have their own built-in cleaning mechanisms that are often more efficient than system ones. On Telegram, go to Settings β Data and Memory β Memory Use. Here you will see clear cache statistics. Click Clear cache, and the app will delete all downloaded media that are not necessary for displaying text correspondence.
For YouTube, the procedure is a little different. Go to the app's settings, find the General or App section (depending on version), and select Clear Data or Clear Cache. Also inside the app itself, in Settings β General, there's a Settings Reset option that helps if the video player isn't working properly. Regularly cleaning these two apps can free up to 30% of the memory you're using.
WhatsApp is more complicated because it stores databases and media files in shared folders. It's best to use the built-in storage management tool: Settings β Data & Storage β Storage Management. Here you can sort files by size and delete the large videos that take up the most space, leaving text messages intact.
