How to Clear Cache on All Apps Immediately on Xiaomi: The Complete Guide

Owners of Xiaomi, Redmi and Poco smartphones sooner or later face a shortage of internal memory, even if the device has an impressive amount of storage. The main reason for filling disk space is often temporary files accumulated by installed programs that are no longer useful but continue to take up space. App cache is a buffer zone where data is stored to speed up the software, but over time its bloating leads to slowdown and errors.

Users often wonder if there is a magic button or hidden menu that allows you to remove garbage files from all programs at once. Unfortunately, in the standard shell of MIUI and the new HyperOS, the direct function “Clear the cache of all applications” in the usual form has long been absent, due to the security limitations of Android.

In this article, we will take a look at all the cleaning tools available, from built-in Security tools to advanced computer-based methods. You will learn how to safely free up gigabytes of space without losing important logins, passwords and settings for your favorite services. Cache deletion does not affect personal user data such as photos, contacts or instant messaging.

Why you need regular cleaning of cache on Xiaomi smartphones

Many users mistakenly believe that cache is malicious files that need to be deleted daily, but in fact, cached data is created to make apps run faster and consume less traffic when they re-access content, such as Instagram storing preview photos viewed, and the browser storing images of visited sites so that the next time you log in, the page loads instantly.

The problem arises when the cleaning algorithms fail to work correctly, or the application contains errors in the code, leading to endless growth in the size of temporary files. In such cases, the cache can grow to several gigabytes, taking up space that could be used to install new games or store media files, this is especially critical for models with a small amount of internal memory, such as 64 or 128 GB.

Also, overflowing or corrupted cache can cause the operating system to run unsteady, you may notice that the phone starts to hang when switching between tasks, and some applications suddenly close immediately after launch, and regular prevention helps keep MIUI in good shape and avoid program conflicts.

It's important to understand the difference between cleaning the cache and cleaning the data. If the first operation is safe and only removes temporary debris, the second one returns the application to the "post-installed" state, erasing all your settings and authorizations, so when it comes to mass maintenance of the system, we are talking about temporary files.

💡

Cache speeds up applications, but its excess slows down the system and takes up space, so periodic cleaning is necessary for the stability of Xiaomi.

Use of the built-in "Security" application

The most affordable and safe method for the average user is to use a regular tool from the shell developers. Each Xiaomi smartphone preinstalled system application Security (Security), which has deep access rights to the system and can effectively manage memory.

To get started, open the app and find the Cleanup section. The system automatically scans the device for temporary files, remnants of deleted programs and other debris. Once you complete the scan, you will see a Cleanup button that will delete the files found. However, it is worth noting that the standard scanner often acts superficially and does not always get to the cache of heavy applications like TikTok or Telegram.

For a deeper cleanup, the menu often includes Deep Clean, where the system offers to delete large files, duplicate photos and, most importantly, the app cache, you can choose specific programs or agree to clean the entire list, a method that is most preferable for those who do not want to risk the stability of the system.

• 📱 Open the Security app on the home screen.
• 🧹 Click on the Cleanup icon and wait for the analysis to be completed.
• 🗑️ Select Deep Clean to access the app cache.
• ✅ Check the required programs and confirm the deletion of files.

Despite its convenience, it has a limitation: it doesn’t always delete the cache of “all apps at once” in one click, requiring manual confirmation for each category or program.This is done to protect against accidental deletion of important data, but can be annoying if you need a quick cleanup.

💡

Use the Deep Clean feature regularly to prevent gigabytes of garbage from accumulating that a standard scanner may not notice.

Mass cleaning through the application menu in the settings

If the built-in scanner didn't work, you can use more detailed control through system settings, which allows you to see the real cache weight for each program you install and make an informed decision, and the path to this menu can vary slightly depending on the version of Android and the shell.

Go to Settings, then select App and then All Apps, and you'll see a complete list of installed software, and you'll find it convenient to sort through the filter menu (three dots in the corner) to sort applications by size, which will help you identify memory eaters that are often hidden among the rarely used utilities.

Unfortunately, in modern versions of MIUI 12/13/14 and HyperOS, the Clear Cache button for all applications was immediately removed in favor of Google's privacy policy. Now the user has to log into each application separately, select Memory and click Clear Cache. This is a long time, but ensures that you do not delete extra.

⚠️ Warning: Be careful when cleaning the data in this menu. Do not confuse the "Clear Cache" button with the "Clear All" or "Reset" button, otherwise you will lose progress in games and authorization on social networks.

There is a little bit of a life hack to speed things up. You can quickly scroll through the list of apps, and if you know for sure that a particular program (like a news aggregator) is storing a lot of garbage, you should clean it up quickly. For Google Play Services or MIUI System, it is better not to touch the cache without an urgent need, as this can cause synchronization failure.

Using Developer Mode and ADB for Advanced

For those looking for a way to clear the cache on all apps at once and not afraid of the command line, there is a method using Android Debug Bridge (ADB). This tool allows you to send system commands directly, bypassing the limitations of the graphical interface. USB-cable.

The first step is to activate the developer mode on your smartphone. Go to Settings → About Phone and quickly press 7 times on the MIUI Version (or OS Version). After the message “You became a developer” appears, go back to the main settings menu, find the Additional → For Developers section and turn on the USB Debugging switch.

Connect your phone to your computer and open the ADB console. To clear the cache of all applications at once, you can use a special command that forcibly closes the background processes and clears temporary files. However, there is no universal command to clear everything for user data in ADB, but you can use scripts to clean the Dalvik cache or system cache, which requires root rights.

adb shell pm trim-caches 999999999

This team tries to free up space by removing the application cache until the specified free space value (in this case, almost complete cleaning) is reached. It is important to understand that executing such commands requires an installed SDK Platform-Tools platform on the PC. This is the most powerful method, but it requires technical literacy.

• 💻 Install the drivers and ADB on your computer.
• 🔌 Connect your smartphone with a cable and allow debugging on the screen.
• ⌨️ Enter adb shell pm trim-caches 999999999 at the terminal.
• 🔄 Wait for the command to be executed and restart the device.

Automation of the process with third-party utilities

Because Xiaomi’s built-in tools don’t always allow you to do a one-click cleanup for everything, specialized apps from the Google Play Store come to the rescue. Programs like Clean Master, CCleaner or Files by Google have special permissions (Usage Access) that allow them to simulate user actions and clean the cache en masse.

When it first runs, it will ask for a number of permissions, you will need to allow access to the device and possibly enable Accessibility Service, which will allow the application to automatically press the clean buttons in the system menu faster than a human would, and it's a legal way to bypass interface constraints.

However, using third-party software has its own risks: it consumes resources, displays ads and can collect data about which apps you use, and on modern versions of Android, their effectiveness is reduced: the system often blocks their attempts to clear the cache without direct user confirmation for each application.

If you choose the path of third-party apps, give preference to trusted developers like Google or big antivirus companies. Avoid questionable “accelerators” that promise to increase RAM by 200% – this is a marketing ploy that has no technical basis.

Cleaning the cache of Google system services and services

Special attention should be paid to system components that work in the background constantly. Google Play, MIUI Daemon and Android system process also have their own cache, and cleaning them can solve problems with updating applications or synchronizing accounts.

To clear the Google Play Store cache, go to Settings → Apps → All apps, find the Google Play Store. From the menu that opens, select Memory and click Clear Cache. A similar procedure can be done for Google Play Services. This often helps if the app store isn't working properly.

Android’s system process also accumulates temporary data, which is safe to clean, but can cause the phone to take a little longer to boot after a reboot, as it has to re-form the necessary files, only if there are obvious problems with the speed of the interface.

⚠️ Warning: Do not attempt to delete system application data through the file manager manually unless you know the exact purpose of the folders.This can lead to a "bootloop" (cyclic reboot) of the phone.

You can also use Recovery mode to clean up your system debris deeply. When you boot your phone (clambing Volume+ and Power), select Wipe Cache Partition, which deletes temporary system files but doesn't touch your personal data (photos, contacts), which is a great way to refresh your system after a major firmware update.

💡

Cleaning the cache of Google and MIUI system services often solves problems with hang-ups and update errors without requiring a complete reset.

Preventing and optimizing memory in the future

To make sure that the question of how to clear the cache on all applications at once xiaomi is no longer relevant, it is worth introducing the habit of regular prevention: do not allow the memory to be filled up “on a roll”: When less than 10-15% of the total volume is free, the speed of the flash memory drops, and the system begins to slow down.

Use cloud storage for photos and videos. Services like Google Photos or Mi Cloud allow you to store originals online, leaving only compressed copies on your device or deleting them altogether after synchronization, freeing up huge amounts of space that would otherwise take up media files.

Also watch for heavy apps: Messengers like Telegram and WhatsApp have a habit of storing all the photos and videos they’ve watched in their phone’s memory, and they have a Data Use feature in their settings, where you can set up autodelete media files or limit the cache size.

• ☁️ Set up automatic synchronization of photos with the cloud.
• ⏳ Enable autodelete messages in messengers through 3-6 months.
• 📉 Regularly check the list of the most voluminous applications in the settings.
• 🔄 Once a month, reboot your smartphone to reset the system cache.

Compliance with these simple rules will allow your Xiaomi to work quickly and consistently throughout its life. Remember that software hygiene is as important as careful physical handling of the device.
