How to Clear the Cache of All Apps Immediately on Xiaomi Redmi

Owners of Xiaomi and Redmi smartphones sooner or later face a slowdown when the drive is full of temporary files. App cache is a useful mechanism for speeding up the download of programs, but its uncontrolled growth can take up gigabytes of space. Clearing this data allows you to return the device to its former sharpness and free up valuable space for photos or games.

With an Android operating system with a MIUI shell or HyperOS, memory management is specific. Standard methods suggest cleaning each application separately, which takes hours, but there are proven ways to clean up bulk. Understanding the difference between user data and temporary files will help avoid accidentally deleting important correspondence or account settings.

The following sections of the article contain step-by-step algorithms that will be suitable for most Xiaomi models. We will consider both the standard system tools and more advanced methods available through hidden menus.

Why does the cache take up so much space on Redmi?

Many users mistakenly believe that cache is garbage that needs to be removed daily. In fact, cached data is created to make the application run faster and not load the processor every time you log in. For example, Instagram or TikTok store the video thumbnails you watched so that when you re-flick the tape, they load instantly.

The problem arises when app developers don't set limits on cache size, or when a user is actively using a lot of heavy software. Over time, a folder with temporary files can grow to unimaginable sizes, blocking the installation of system updates, at which point the smartphone's RAM begins to work at its limit, causing interface friezes.

⚠️ Warning: Cache removal does not affect your logins, passwords, and game saves, but can temporarily slow down the first app launch after cleaning up.

MIUI aggressively manages background processes, but sometimes it requires manual intervention. If you notice that notifications come with a delay or applications fly out at startup, this is a sure sign of crowded storage. Regular monitoring of temporary files becomes a mandatory procedure for owners of models with a small amount of internal memory.

Use of the built-in Security application

The easiest and safest way to clear the cache of all applications at once is to use a standard tool from Xiaomi. Security is preinstalled on every device of the brand and has access to system partitions closed to third-party programs. It analyzes the amount of garbage occupied and offers (one-tap) cleaning.

To start the procedure, you need to find an icon on your desktop called Security or Security, which usually has a green shield as its logo. Inside the interface, we're interested in the Cleanup section, which scans the device for temporary files, residual data and cache. Once the scan is complete, the system will show you the amount of files that can be deleted without harming the operation.

• 📱 Click on the Clean button in the app’s main menu to remove obvious debris.
• 🗑️ Select Deep Cleaning to analyze large files and duplicates.
• 📂 Go to the Applications section inside the cleaning menu for detailed cache management.

It is important to note that standard cleaning may not affect the cache of some system services Google Play or Xiaomi Services. For more thorough processing, go to the application management subsection inside the security utility, where you can select the option of sorting by cache size and manually walk through the most “heavy” positions if the automatic mode missed something important.

Mass cleaning through system settings

If the built-in utility doesn't display the full picture for some reason, you can use the standard Android settings menu, which requires more action, but gives you full control over each component installed. Unlike third-party clinchers, the system menu has no ad units and shows the real state of the storage.

Go to Settings, then select App and then All Apps, and here's the full list of installed software, and to speed up the process, you can sort the list by size of space by clicking on the appropriate sort icon at the top of the screen, and that will immediately bring the program with the highest cache volume to the first positions.

When you log in to a specific application card, you will see two buttons: Clear the cache and Clear everything. Be careful: the Clear All button (or Delete Data) will delete not only temporary files, but also your authorization, settings and local saves. To clean the cache without losing data, you need to press the cache clean button for each application separately, which can take time, but ensures the safety of profiles.

Cleaning through the special features menu

There is a lesser-known method for accessing a hidden application management menu where the mass cleaning function is more conveniently implemented, a method that is often overlooked, although it is native to the MIUI shell. It is especially useful when you need to quickly reset the status of a suspended service without deleting its data.

To activate this mode, go to Settings, then Advanced Settings and select Special Options. In this menu, you should find Delete Data or Clear all cache (the name may vary depending on the firmware version and region). After turning on the slider in the notification curtain, a new icon will appear that causes the Quick Cleaning Panel.

• 🔧 Activate access through the menu Special features in settings.
• 📉 Use the widget that appears to quickly clean the cache of the current application.
• ⚙️ Set up automatic cleaning when you reach a certain filling threshold.

This method allows you to avoid going too deep into the settings of each application. However, it is worth considering that on new versions of HyperOS, Google restricts access to such features for security reasons. If you do not find this item, it is possible that your version of the system blocks this functionality, and then you should turn to alternative options.

💡

Use the memory extension function in the settings only if you really don’t have enough RAM. To clean the cache, it will not help, but only create an additional load on the flash memory, accelerating its wear.

Engineering menus and hidden commands

For advanced users who do not have enough standard tools, there is access to the engineering menu through the Internet. USSD-This method allows you to clear the system cache that is not visible in the normal interface. Entering code ##6484## opens the testing menu where you can find the partitions associated with memory.

Be extremely careful when using the engineering menu. Incorrect actions in sections labeled as Factory Test or Hardware Test can cause a recalibration of the screen or communication modules. We are only interested in cleaning temporary files, so avoid items that contain the words "Format", "Wipe Data" or "Reset".

⚠️ Warning: Engineering menus are for service centers, and changing unknown parameters can lead to unstable operation of the radio module or loss of warranty.

An alternative to manual commands is to use ADB (Android Debug Bridge) via a computer. By connecting your smartphone over USB and enabling debugging, you can execute an adb shell pm trim-caches 999999999999, which forcibly clears the cache of all applications, freeing up space, a method considered the most effective for mass cleaning without losing user data.

adb shell pm trim-caches 999999999999

Using ADB requires installing drivers on a PC and basic command line knowledge, but the result is worth it. The system will determine which files are redundant and delete them, ignoring important system logs, which is ideal for preparing a device for sale or before installing a heavy system update.

💡

The safest and most effective way to clean up is to use the ADB command or the regular Security app, as they are guaranteed not to delete your personal data.

Automation and third-party utilities

If manual cleaning seems too time-consuming, you can use automation. MIUI has a built-in task scheduler in the Security app, which allows you to set up automatic garbage cleanup when the phone is on charge and the screen is off, which saves the user from having to remember the maintenance procedure.

Third-party apps from Google Play, such as Files by Google or SD Maid, can also be useful, have more flexible filtering settings and can find tails of remote programs. However, installing such programs on Xiaomi devices is often redundant, as they consume battery resources in the background, trying to replace the system functionality.

• 🤖 Set up automatic cleaning in the Safety app on schedule.
• 📉 Use Files by Google to find duplicates and rarely used apps.
• 🚫 Avoid “accelerators” with aggressive advertising that only load the system.

The key to optimizing is to keep memory overflows from critically high; using embedded tools once a week is more effective than cleaning when the phone is already braking; and good digital hygiene extends the life of the drive and keeps the interface running at a high level.
