Modern Xiaomi and Redmi smartphones have powerful hardware, but over time, even the fastest devices can start to run slower. The main reason for this phenomenon is often bloated app cache and system debris that accumulates during the use of the gadget. Understanding how to clean the cache of the Xiaomi Redmi phone is a key skill for any owner who wants to maintain high performance.
Caching is a mechanism that allows applications to save temporary files to quickly load data when re-extracted. However, when these files become too large, they begin to take up precious space in memory and can cause conflicts in the operation of the MIUI or HyperOS operating system. Regular cleaning helps to free up space and eliminate errors associated with corrupted temporary data.
In this article, we will take a look at all the cleaning methods available, from built-in tools to manually deleting files through an engineering menu, and learn to distinguish between safe actions and those that could lead to loss of important data.
What is cache and why you should clean it on Redmi
Xiaomi’s cache serves as a buffer zone for the time data of frequently used programs, such as thumbnails of images in a gallery, saved pages in a browser or intermediate social media files, and the main purpose of cache is to speed up the application so that you don’t have to download the same data from the Internet or from the disk every time.
However, uncontrolled cache growth has negative consequences: When the volume of temporary files reaches a critical mass, the system begins to spend more resources on indexing and finding the necessary data, which causes lags and slowdowns of the interface, and old cache files can contain errors that provoke sudden crashes of applications.
Clearing the cache on Redmi is especially relevant for devices with a small amount of internal memory. A crowded partition of system data can block the installation of operating system updates or new applications. Regular maintenance allows you to keep the smartphone in optimal condition without having to buy a new model.
- 🚀 Accelerate the launch of heavy apps and games by removing conflicting temporary files.
- 💾 Freeing up gigabytes of free space for photos, videos and documents.
- 🔋 Reducing the load on the processor, which indirectly affects the battery life of the device.
- 🛡️ Removing software errors caused by corrupted or outdated cache data.
It's important to understand the difference between cache cleaning and data resetting. If you choose the "Clear Cache" option, your logins, passwords and game progress are saved. If you choose "Erase Data" or "Clear Everything", the application will return to state immediately after installation, and all personal information will be deleted. Be careful when choosing the type of cleanup in the settings.
Use of the built-in Security application
The easiest and safest way to clear the cache on Xiaomi Redmi is to use the regular Security app, which is pre-installed on all devices of the brand and optimized specifically for working with the MIUI shell. This tool scans the system for junk files, remnants of deleted programs and temporary data.
To get started, run the Security app and click on the large green Cleanup button. The system will automatically analyze the amount of debris it occupies. Once you complete the scan, you will see a list of files that can be deleted without risking system stability, usually advertising files, installer residues and browser cache.
☑️ Checklist for quick cleaning
The Cleanup feature in the security app runs in the background and does not require deep technical knowledge. However, it is worth noting that it does not always remove the cache of heavy apps like Telegram or Instagram completely, leaving some temporary files for speed.
⚠️ Note: The Security app may suggest that you delete files you recently downloaded but didn't save to another folder.Always check the file list before final cleanup confirmation so you don't lose important documents.
In the Security settings, you can schedule automatic cleaning, which is convenient for users who don't want to monitor memory status regularly, and the system will notify you of the accumulation of garbage and suggest that you remove it with a single click.
Manually cleaning the cache of individual applications
If a particular application is not working properly or takes up too much space, manually clear its cache through system settings. This method allows you to pinpoint the problem programs without affecting the data of other services. → Annexes → All applications.
In the list, find the app you want, like YouTube or Chrome. Click on it to open the app information page. Here you will see the Clean button (or broomstick icon) and the Memory option. Click on Clear will only delete temporary files, leaving your accounts and settings intact.
What to do if the cleaning button is inactive?
For some applications, such as Google Maps or navigators, the cache can take several gigabytes because of the stored offline cards. In such cases, manual cleaning through settings is the only way to quickly return free space. Once cleaned, the application can load a little longer on the first run, as it will have to re-create temporary files.
Use a Settings Search if you can't find the app you want in the general list. Type the program name into the search bar at the top of the Settings screen, and the system will immediately redirect you to the application management page, which saves time on devices with a lot of software installed.
Deep cleaning through the storage menu
In modern versions of MIUI and HyperOS, there is an extended memory management menu that gives a more detailed picture of disk occupancy. To get there, go to Settings → About Phone → Storage. This shows the visualization of occupied space with different types of files.
In this section, you can see how much space apps, images, videos and system files take up, and by clicking on the Apps category, you get a sorted list of programs by memory, which helps you identify the hidden eaters of space that you might not have known about.
| Type of data | Description | Is it safe to remove |
|---|---|---|
| Cash app. | Temporary files to speed up work | Yes, it's completely safe. |
| Application data | Logins, settings, progress of games | No, it'll lead to a reset. |
| Residual files | Fragments after deleting programs | Yes, we can remove. |
| System cache | Operating system files | Only through the rivers. |
The Cleanup feature in the storage menu often offers more aggressive deletion scenarios than a standard security application. It can suggest removing large files, long-unopened documents or duplicate photos. Read descriptions carefully before deleting so as not to erase the desired ones.
💡
Tip: Check the Downloads folder in the file manager regularly, and APK installation files are often downloaded there, which are no longer needed after installing programs, but take up space for months.
Cleaning the cache in Recovery mode
The deepest level of cleaning is to remove the system cache through the Recovery Mode menu, a method recommended if the phone is unstable, freezes or does not load normally after an upgrade, and allows you to clear the cache partition that is not available from the normal operating system.
To enter Recovery mode, turn off your smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo or recovery menu appears. Depending on the version of the shell, the menu can be touch-sensitive or controlled by volume buttons.
Wipe Data → Wipe Cache → ConfirmIn the menu, select a language (if available), then find Wipe Cache or Clear Cache. Confirm the action. It is important not to confuse this item with Wipe All Data, which will completely reset the phone to factory settings with loss of all files. After cleaning, select Reboot to reboot.
⚠️ Note: In Recovery mode, navigation can be done with volume buttons (up/down) and power button confirmation. Carefully avoid accidentally selecting a full data reset (Wipe All Data), as it will be impossible to restore files after that without a backup copy.
This method is especially useful after major firmware updates, when old system files may conflict with new ones.Cache clearing in Recovery does not affect your personal photos, contacts and installed applications, removing only temporary system data.
Automation and useful maintenance tips
So you can set up automatic scripts to avoid manual cleaning all the time, and the Security app has a Speed feature that clears RAM when you start up, and you can also turn on memory filling notifications so that the system itself warns you to clean up.
For advanced users, there are third-party file managers such as Total Commander or FX File Explorer that allow you to find and delete hidden cache folders without deleting the applications themselves.
💡
Regularly restarting your smartphone (every 3-4 days) also helps to automatically clean some temporary files and free up RAM, improving overall system responsiveness.
Remember to clean your browser cache if you're actively surfing the web. In Chrome or the built-in Mi Browser, you can set up automatic deletion of your history and cache when you close a tab or incognito mode, which preserves privacy and saves space.
If after all the cleaning procedures the phone continues to work slowly, perhaps the problem is not the cache, but the wear of memory or lack of resources for modern applications, in which case it is worth considering resetting to factory settings or replacing the device with a more productive one.
