Xiaomi’s modern smartphones are famous for their performance, but over time, even the most powerful devices can start to work slower. The main reason for this phenomenon lies in the accumulation of temporary files, residual code of remote programs and the sprawling cache of active applications. Users often notice that free space in memory is running out and the system begins to hang when switching between tasks.
The cleaning process does not require any technical knowledge or superuser rights (Root). The built-in MIUI and HyperOS shell tools allow you to effectively manage storage, delete unnecessary data and return the device to its previous speed. In this article, we will discuss in detail all available methods, from standard cache cleaning to full reset of specific applications, so you can choose the most suitable option for your case.
Understanding the Data Structure of Android Applications
Before you start deleting files, it’s important to clearly understand the difference between the types of data that take up space in your smartphone’s memory. Many users mistakenly believe that “cleaning data” and “cleaning cache” are the same thing, although these actions lead to diametrically opposite results. Cache is a temporary file that an application creates to quickly load frequently used content, such as images from social media feeds or web browser pages.
Unlike temporary files, application data includes your personal information: settings, logins, game saves, downloaded maps for navigation and correspondence history. Deleting these files will cause the program to return to the “as after installation” state and you will have to re-authenticate, which is why backing up critical data is a must before deep interference with the file system.
The Android system on Xiaomi devices strictly separates these categories for user safety. When you see that the messenger takes several gigabytes, most often the lion’s share of this volume falls on media files and cache, and not on the executable code of the program.
- 📱 Cache: Temporary files to speed up work, safe to delete.
- 🔐 Data: Personal Information and Settings, Deletion Resets the App.
- 📦 APK-File: Installation package of the program, occupies a fixed volume.
- 🗑️ Residual garbage: files left after deleting applications.
⚠️ Note: Before performing the operation "Clear all data" make sure that you have up-to-date backups of important chats and documents, as it will be impossible to restore them with standard means after resetting.
Use of the built-in "Security" application
The easiest and most affordable way to clean up memory is to use a regular tool from Xiaomi developers. Security is preinstalled on every device of the brand and contains a powerful module "Cleanup". This tool automatically scans internal storage, identifying temporary files, advertising debris and remnants of remote programs. Deep scanning usually takes no more than a minute to run even on models with large storage.
Once the analysis is complete, the system will prompt you to delete the files you find at a single click, but experienced users prefer to manually check the categories "Large Files" and "Unused Applications" so as not to accidentally delete important documents or rarely used but necessary programs.
It is important to note that the Cleanup algorithms are constantly updated through Google Play and the GetApps store. Regular use of this tool helps keep the system in good shape and prevents critical memory filling, which could lead to unstable interface operation.
💡
Set up automatic cleaning in the Security app so that your smartphone will remove the garbage itself when the free space drops below 10%.
And you can also find a section on the cleaner menu called Deep Cleaning, where you analyze specific apps like WhatsApp, Telegram, or Instagram, where you can selectively delete old videos from chat rooms or huge files sent by colleagues without affecting text history, which makes the process more pointy and secure for user data.
Manually cleansing cache and data through settings
If automatic tools fail to produce the desired result or you want to reset a specific problem application, you need to use manual control through system settings. This method gives full control over each installed component of the system. To start, go to the Settings menu, then select the Application section and click All Applications. Here is the full list of installed software.
Find the app you want (like YouTube or your browser) and tap it. In the menu that opens, you'll see the Clean button (or "Storage" depending on the version of MIUI). Clicking on this button will open two options: Clear cache and Clear all data. The first option is safe and recommended for regular maintenance, the second is radical and is used to eliminate errors or completely reset the program.
☑️ Checklist for manual cleaning
It is worth mentioning that for some system applications, the data cleanup button may be inactive or hidden, an Android security mechanism that prevents accidental disruption of critical services such as the System Frame or Google Play Services. Interference with such components without proper qualification can lead to a cyclical reboot of the device.
| Action. | Impact on data | Necessity of entry | Risk of file loss |
|---|---|---|---|
| Clearing the cache | Deletes temporary files | Not required | No. |
| Clearing the data | Complete resetting of settings | Required again | High-pitched |
| Removal of updates | Return to the factory version | Depends on the app. | Medium. |
| Deletion of the annex | Complete removal | Installation required | Yeah, if there's no backup. |
Once cleaned, it is useful to restart the device, allowing Android to re-index the files and correctly display the freed-up space in the common interface. Often users notice that immediately after the procedure, the amount of free memory is displayed incorrectly, and the reboot solves this visual error.
Storage management in new versions of MIUI and HyperOS
Owners of modern Xiaomi models like the Xiaomi 14 or Redmi Note 13, which are powered by HyperOS or the latest versions of MIUI 14, may notice changes in the memory management interface. The company has introduced smarter data compression algorithms and new memory visualizers. Now, a detailed diagram is available in the Storage section showing which file types occupy the most space.
The new system also offers a memory extension feature that uses a portion of internal storage to increase RAM. While this helps in multitasking, using it actively can wear out flash memory faster and take up space that could be used for applications. In the memory management menu, you can turn off this option or adjust its size, which sometimes frees up several gigabytes.
The new firmware focuses on duplicate analysis, automatically finds identical photos, videos and documents, prompting you to delete copies, and this is especially true for users who are actively using instant messengers that save many copies of the same images in different folders, the tool runs in the background and does not require constant user intervention.
In addition, the updated versions of the shells have improved the mechanism of “freezing” rarely used applications, the system automatically limits the background activity of such programs, which not only saves battery power, but also prevents their cache from growing in the background, which makes cleaning less frequent, since the applications simply stop generating garbage while you are not using them.
Cleaning up garbage in popular messengers
Special attention should be paid to messengers, which are traditionally the main “eaters” of memory on Xiaomi smartphones. Telegram, WhatsApp and Viber have their own built-in tools for cache management, which often work more efficiently than system cleaners. Telegram, for example, you can set up automatic deletion of the cache of media files after a certain time (week, month), which keeps the size of the application in check.
WhatsApp is more complicated because it stores all the media it receives in a shared folder that is available to the system, but inside the chat settings, there's a "Storage" section where you can sort the dialogues by size and remove attachments from specific correspondence, which allows you to clear gigabytes of video while preserving your text history.
⚠️ Note: When you clean your messenger data through your Android system settings (Clear All Data button), you will lose access to your correspondence if you do not have a backup enabled in Google Drive or iCloud. Use the built-in cleanup tools inside the apps themselves!
Viber also has a large number of stickers and GIF-Regularly checking the Memory section in Viber settings allows you to delete unnecessary collections. Android/media through the file manager, as some messengers may leave orphaned files (orphans) after deleting chats.
Using cloud storage like Google Photos or Yandex Drive, in conjunction with the Free Space feature, allows you to transfer all photos and videos to the cloud by deleting their local copy. This frees up huge amounts of memory, leaving access to media files over the Internet. For Xiaomi users with limited internal memory (64 GB or less), this becomes a vital procedure.
Radical methods: reset to factory settings
If neither cleaning the cache nor deleting the apps helped speed up the device and the memory is constantly filled with obscure files, it may be time for a complete reset, a procedure known as Hard Reset or Settings Reset, returns the smartphone to the state in which it left the factory conveyor.
Before starting the procedure, make sure that the battery is at least 50% charged and all important data is stored on an external medium or in the cloud. Reset is performed through the Settings menu → About the phone → Resetting → Erase all data. The system will ask you to enter the screen unlock password and the password from the Mi Account to confirm the identity of the owner.
What if the phone doesn’t turn on after resetting?
Once the process is complete, the phone will restart and the initial setup will take 5 to 15 minutes, during which time the system optimizes applications and adjusts basic parameters, and you should not panic if the device will work slowly or heat up in the first half hour after turning on, which is a normal process of background indexing and loading services.
Using this method ensures the removal of any hidden viruses, software bugs and file system conflicts that may have accumulated over the years of use. For many Xiaomi users, annual full reset becomes a tradition that allows you to extend the life of the smartphone for the second and third year of operation without losing performance.
💡
A complete reset is a last resort that solves 99% of software problems, but requires careful preparation and backup of data.
