How to Clear Cache in All Apps at Once on Xiaomi: 5 Working Ways

Why the cache needs to be cleaned regularly and when it really helps

Application cache on Xiaomi is a temporary file that is created to speed up programs. They store data about recent actions, uploaded images, videos and other elements so that the next time the application starts up faster. However, over time, the cache grows to several gigabytes, taking up precious space in memory and sometimes causing the smartphone to slow down.

Many users of Redmi, POCO and other Xiaomi lines face a situation where it takes too long to manually clear the cache for each application. This is especially true if the device has 100+ programs installed. In such cases, mass cleaning becomes not a luxury, but a necessity. But it is important to understand that deleting the cache does not always solve performance problems. If the phone slows down due to a lack of RAM or a weak processor, cleaning temporary files will only have a short-term effect.

In this article, we’ll look at all the available ways to mass clear cache on Xiaomi, including hidden MIUI features, ADB commands, and third-party utilities, and you’ll learn where it really helps and when to pay attention to other optimization methods.

Method 1: Standard cleaning through MIUI settings

The easiest and safest method is to use built-in MIUI tools. It does not require superuser (root) rights and is suitable for all models, including the Redmi Note 12, POCO X5 and Xiaomi 13. However, this method has a limitation: it clears the cache only for those applications that support this feature through the system menu.

To take advantage of it:

1. Open the Settings → Applications.
2. Slip on the three dots in the top right corner and select Cache Cleanup.
3. Confirm the action by pressing OK in the window that appears.

The system will automatically scan all installed programs and delete their temporary files, which can take anywhere from a few seconds to a minute depending on the number of applications.

⚠️ Note: This method does not clear the cache of system applications (e.g. com.android.systemui or com.miui.home.

It’s also worth considering that after cleaning up some applications (such as social networks or instant messengers) can take longer to load on the first run, as they will have to cache data again.

Method 2: Use MIUI Optimization (Hidden Function)

MIUI has a hidden MIUI Optimization menu that allows deep cleaning, including mass cache removal, which works on most Xiaomi devices, but the path to it may vary depending on the shell version.

Instructions for MIUI 12/13/14:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that appears, select Battery Information (or Usage statistics in English).
3. Slip on the three dots in the top right corner and select MIUI Optimization.
4. In the window that opens, look for the Clear Cache for all apps option and confirm the action.

This method removes the cache of all applications, including system ones, which can be useful if standard cleaning has not yielded results.

⚠️ Note: On some models (e.g. Redmi 10s) MIUI 12.5) The combination ##4636## may not work. ADB-teams (mode 4).

If the MIUI Optimization menu is missing, it means that the manufacturer has disabled it in your firmware version, in which case alternative methods remain.

Method 3: Cleaning with Recovery Mode (for advanced users)

If your Xiaomi is slowing down a lot and standard methods aren’t helping, you can try cleaning the cache through Recovery Mode, which removes Dalvik-cache and other system temporary files, which sometimes solves performance problems.

Step-by-step:

1. Turn off your smartphone.
2. Press the Power + Volume button combination up and hold them until the MI logo appears.
3. From the Recovery menu, select the language (if required), then go to Wipe & Reset.
4. Select Wipe Cache (not to be confused with Wipe All Data!).
5. Confirm the action and wait for the process to be completed.
6. Reboot your device with Reboot → Reboot to System.

This method doesn't delete user data, but it resets some system settings. Once rebooted, the first application launches may take longer, as they'll have to recover the cache from scratch.

If performance problems persist after cleaning through Recovery, this may indicate more serious problems, such as memory fragmentation or firmware errors, in which case it is worth considering factory resets or flashing the device.

💡

If applications are slower after cleaning the cache, give them time to re-caching the data, and usually the performance is restored after 2-3 runs.

Method 4: Mass cleaning of cache through ADB (without root)

For users who aren’t afraid of the command line, there’s a powerful tool called Android Debug Bridge (ADB), which can remove the cache of all apps, including system ones, without the need for superuser rights. This method works on any Xiaomi device, including the POCO F4, Redmi K50 and Xiaomi 12T.

What will be required:

• 🖥️ A computer with installed Xiaomi drivers and ADB.
• 📱 Included debugging by USB on a smartphone (Settings) → The phone. → Version. MIUI (tap 7 times) → Additional settings → Developer parameters → Debugging by USB).
• 🔌 USB-plug-in.

Instructions:

1. Connect your smartphone to your computer and confirm the debugging permission.
2. Open the command prompt (CMD) or Terminal and type:

adb devices

Make sure your device is listed. Then run a command to clear the cache of all applications:

adb shell pm trim-caches -1

This command compulsorily clears the cache for all user and system applications, a process that can take a few minutes.

For deeper cleaning, an alternative command can be used:

adb shell "su -c 'find /data -name 'cache' -exec rm -rf {} +'"

⚠️ Warning: The second command requires root rights and can cause the system to malfunction if executed incorrectly. Use it only if you are confident in your actions.

Important: After completion ADB-commands some applications (such as Google Play Services) can automatically restore cache. To avoid this, turn off auto-update applications in the Google Play settings.

Method 5: Third-party applications for automatic cleaning

If you don't want to mess with settings or commands, you can use third-party utilities, which offer a user-friendly interface for bulk cache cleaning, and some even allow you to set up automatic deletion on a schedule, but it's worth remembering that not all programs are equally secure.

Top.-3 Proven applications for Xiaomi:

• 🧹 SD Maid is a powerful tool for cleaning up garbage, including cache, residual files and duplicates. There is an AppCleaner feature for mass cache removal.
• 🚀 CCleaner is a popular utility with a simple interface that allows you to clear cache, history and temporary files in one click.
• 🔍 Files by Google is Google’s official Cleanup app that analyzes and deletes unnecessary files, including cache.

How to use SD Maid:

1. Install the app from Google Play.
2. Run it and provide the necessary permissions.
3. Go to the AppCleaner section.
4. Tick the app cache you want to clear (or click Select All).
5. Slip the run and wait for the process to be completed.

⚠️ Note: Some cleaning applications (e.g. Clean Master) may contain aggressive advertising or collect user data.

It’s also worth remembering that third-party programs can’t always clear the cache of MIUI system applications, and you’ll still need an ADB or Recovery Mode.

What if cleaning the cache doesn’t help?

If the smartphone still slows down after deleting the cache of all the apps, the problem may lie deeper.

• 🔄 Reboot the device. Sometimes bugs are at work. MIUI Resolved by a simple reboot.
• 🗑️ Cleaning up data from unnecessary applications.
• 📱 Disable the autoload of applications. → Annexes → Autoboot can be banned from the background work of unnecessary programs.
• 🔧 Factory reset: An extreme measure that deletes all data but returns the smartphone to a "clean" state.
• 📲 Update of firmware. New versions MIUI Frequently corrected errors that affect productivity.

It's also worth checking the internal drive, and if the memory is full (less than 10% of the free space is left), the system starts to run slower, in which case it will help:

• Delete unnecessary files (photos, videos, music).
• Transfer of data to SD-map.
• Use the function of the Warehouse in the settings for analyzing the occupied space.

If none of the methods worked, the problem may be in the hardware (for example, worn flash memory), in which case it is recommended to contact the service center.

💡

Cleaning the cache is a temporary solution. For a smartphone to work smoothly, it is important to update the firmware regularly, remove unnecessary applications, and monitor the free space in memory.
