Xiaomi smartphones are famous for their performance and functionality of the MIUI shell, but over time, even the most powerful devices can start to work slower. One of the common reasons for the speed drop is the accumulation of temporary files and garbage in installed programs. Users often notice that free space in memory is rapidly disappearing, and some applications cease to respond correctly to commands.
In this situation, the most effective solution is to force the cleanup of the accumulated data, which allows the program to return to its original state, as soon as it is installed, freeing up precious megabytes and eliminating software failures. It is important to understand the difference between a conventional cache cleanup and a complete data reset, since these processes have different consequences for user information.
Next, we will discuss how to safely perform these procedures, what nuances Android has on Xiaomi devices and when to apply radical cleaning methods, you will learn how to find hidden garbage storage and optimize the operation of your gadget without losing important contacts or photos.
Difference Between Cache Cleanup and Data Reset
Before you start taking action on the settings menu, you need to be clear about what you are going to delete. Many users confuse the concepts of "cache" and "app data", which can lead to the unexpected loss of important information such as logins, passwords and progress in games. Cache are temporary files that the program creates to speed up its work, such as image thumbnails or intermediate calculations.
Unlike temporary files, app data includes all the settings you changed, saved sessions, correspondence history (if it is not synced to the cloud) and program databases. Cache removal is a safe operation that can be done regularly for prevention. Data reset is a more serious procedure that returns the application to a factory state.
- 🗑️ Cache: Temporary files are deleted without losing user settings.
- 🔒 Data: logins, passwords, game saves and program personalization.
- 🚀 Performance: Cache cleaning often solves the hang problem.
- ⚙️ Settings: when resetting data, all parameters will return to standard.
⚠️ Note: Before performing a complete data cleanup, make sure you remember the password from your account in this application, as you will have to log in again.
Standard method of cleaning through Android settings
The most reliable and safe method of removing accumulated debris is built directly into the operating system, and you do not need to install third-party software to access it, which eliminates the risk of accidental deletion of system files or infection of the device. The process takes only a few minutes and is available on any version. MIUI.
To get started, open the main menu and find the Settings icon. In the list that opens, you need to scroll down to the App section, then select All Apps. Here is a complete list of installed software, sorted by alphabet or date of use.
Find a program in the list, such as a "browser" or a "gallery", and click on it. You will be taken to the application information screen, where the Clean button (or broomstick) will be available. When you click on it, the system will offer two options: "Clear cache" or "Clean all", the choice of the second option will result in a complete reset.
☑️ Checking before cleaning
It is worth noting that for some system applications, the data clearing button may be inactive (grey), a security restriction on Android that prevents the user from interfering with mission-critical system components without special permission.
Use of the built-in Security application
The MIUI shell features a powerful system utility called Security, which Xiaomi engineers designed specifically to optimize smartphone performance and protect against malware. Unlike the standard Android menu, the cleaning process is automated and tailored to the specifics of MIUI's background processes.
When you run the Security app, you'll see a big green indicator with a percentage of memory occupied. Clicking on the Cleanup button will start scanning the system. The utility will find temporary files, remnants of remote programs, advertising debris and cache of frequently used applications. It's a quick way to free up space without diving deep into the settings of each application separately.
However, if your goal is to fix an error in a particular application, you should use the Deep Clean function or go to the application management section inside the utility itself, where you can sort programs by space and point to remove the excess.
- 🛡️ Protection: Built-in antivirus checks files before deleting.
- ⚡ Speed: Automatic closing of background processes.
- 📉 Analytics: displaying the dynamics of memory release.
- 🔍 Search: Ability to find large files manually.
Why does cleaning not have a long-term effect?
Clearing data through the Application menu
For advanced users who want to have full control of the process, there is an extended application management menu that allows not only memory clearing, but also permissions, auto-starts and notifications, which is especially useful when standard cleaning does not eliminate glitches.
In this section, you can see detailed memory usage statistics, which show how much space the installation file (APK) takes up and how much user data, and sometimes it is not the application itself that is “heavy” but the garbage accumulated over the years.
It also has the Stop (or Close) function, which forcibly terminates the program before cleaning, ensuring that no file is occupied by the system at the time of deletion, reducing the likelihood of errors.
| Type of data | Description | Impact on work | Security of removal |
|---|---|---|---|
| Cash. | Temporary files for acceleration | Accelerating launch | Completely safe. |
| Data data | Settings and logins | Personalization | Requires re-entry |
| Files. | Uploaded documents | User-generated content | Possible loss of files |
| Permits | Access to camera, microphone | Functional | Resets upon removal |
⚠️ Note: If you delete the banking application data, you will most likely have to re-link the device and undergo a full identification procedure.
💡
Use the AutoRun feature in the app menu to prevent unnecessary programs from running with the system. This will significantly save RAM and battery power for your Xiaomi.
Solving problems with overflowing memory
When memory is overcrowded, the smartphone often starts to work unstable and new applications are not installed, in such cases, standard cache cleaning may not be enough, you need to audit the content and delete really heavy files.
Special attention should be paid to messengers such as WhatsApp and Telegram. They have their own internal storage settings. Often, the folders of these applications store thousands of photos and videos that are duplicated in the gallery. Cleaning through the Android settings does not always affect these attachments, so it is better to use built-in cleaning tools inside the messengers themselves.
It's also worth checking the Download folder. It's often where installation files accumulate. APK, which have already been used, and PDF-Deleting documents that you no longer need can instantly free up a few gigabytes of data.
- 📸 Gallery: Check the folder "Recently deleted".
- 📹 Video: Remove long videos or transfer them to PC.
- 📱 Streaming: Clear Spotify or YouTube cache.
- 🗺️ Navigation: Remove offline maps if they are not relevant.
If the problem is not solved after all the manipulations, it may be the fault of a particular malfunction, in which case it helps to restart the device in safe mode for diagnosis.
💡
Regular cleaning of the cache of heavy applications (social networks, navigators) every 2-3 weeks allows you to maintain a stable speed of the smartphone without the need for a complete reset.
