How to Clean Cache in Xiaomi Phone: The Complete Guide

Xiaomi smartphones are famous for their performance and affordable price, but even the most powerful devices eventually start to work slower. The main reason for the reduced response speed of the system and sudden freezes is often accumulated application cache and system temporary files. When internal memory becomes critically scarce, the MIUI operating system can not effectively manage resources, which leads to interface brakes.

Cache cleaning is not just a way to free up a few gigabytes, but also an effective method of solving software errors. Many users mistakenly believe that deleting temporary files can harm the system, but regular maintenance of data storage is a standard maintenance procedure. In this article, we will discuss all the safe ways of cleaning, from built-in tools to advanced methods for power users.

What is cache and why does it take up memory?

Cache is a buffer memory that stores temporary data to speed up applications. When you launch a browser, social network or game, the system stores interface elements, images and scripts so that the next run does not download them again from the Internet. This greatly speeds up the response of the program, but over time the amount of data can reach several gigabytes.

The problem is that temporary files tend to accumulate and not always delete automatically. Older versions of data can conflict with new app updates, causing operating system failures. For example, if you upgraded Instagram or Telegram and the old cache remains, the application may not work stable or at all.

In addition, a crowded cache directly affects the speed of writing and reading data from the flash memory of the smartphone. When the free space runs out, the memory controller operates in a stressful mode, which leads to heating of the case and rapid discharge of the battery. Regular cleaning allows you to maintain the device in optimal condition without having to reset to factory settings.

⚠️ Caution: Clearing the cache does not delete your personal photos, contacts or correspondence. However, deleting the data of a particular application (not to be confused with cache) can reset its settings to factory.

Use of the built-in "Security" application

The easiest and safest way to free up space is to use a regular tool from Xiaomi developers.The Security app is deeply integrated into the MIUI shell and has access to all system partitions, which allows you to effectively find garbage that is invisible to the user when you normally browse files.

To start the procedure, you need to find an icon on your desktop or in the Tools folder called “Security” (green shield). Once you start the application, the system will automatically scan, but for deep cleaning, you better click on the “Cleanup” button manually. The algorithm will analyze the volume of temporary files, advertising debris and remnants of remote programs.

It is important to distinguish between two types of cleaning in this menu: Cleanup removes temporary system and application files, and Deep Cleanup allows you to select large files, duplicate photos and unused packages. Use the deep cleanup function carefully, checking the file list before deleting so that important documents do not accidentally erase.

• 📱 Click on the “Security” icon on your desktop.
• 🧹 Select the "Cleaning" option for quick scanning.
• 🔍 Go to the Deep Cleanup section for detailed analysis.
• ✅ Confirm the deletion of temporary files found.

⚠️ Note: In the Deep Cleanup section, carefully check the Big Files tab to avoid removing uploaded videos or documents you still need.

Cleaning the cache through system settings

If the built-in analyzer didn't solve the problem with a particular application, you need to use the system settings of Android. This method allows you to pinpoint the cache of only one program, which is especially useful for troubleshooting.>Data from other applications and is more selective.

To get to the menu, open your smartphone settings and search for the Apps section. From the list of all installed programs, select a problematic application, such as YouTube or Chrome. Inside the app menu, you are interested in the Memory or Storage item, which displays detailed statistics on space use.

Here you will see two buttons: Clear Cache and Clear Everything (or Erase Data). The first button deletes only temporary files, leaving your logins and settings intact. The second button completely resets the application to state immediately after installation, deleting all accounts and saves, so use it only in extreme cases.

There is also a hidden menu of engineering tests available through dialing, but for a normal cleaning of the cache, the user needs standard settings. If after cleaning the cache, the application continues to work incorrectly, try to also clear its data by logging in to the account.

Delete temporary files through Explorer

For users who prefer full control of the file system, a manual method through the standard Explorer is suitable. The MIUI shell allows you to see the folder structure where digital debris accumulates, which requires care, since you manually select directories to delete.

Open the Explorer app and go to the root folder of the device, and you're interested in directories called MIUI, Android, and DCIM (if there are thumbnails), but the most effective way to clean up the Download folder, which often contains forgotten APK installation files and documents.

Also worth looking at are social media folders like Telegram and WhatsApp, which store thousands of images and videos that you've viewed in your phone's memory inside their directories, even if you've already seen that content, and removing the contents of the Cache folders inside those directories is safe.

• 📂 Open the “Conductor” and go to the root of memory.
• 🗑️ Find the Download folder and delete old files.
• 📱 Go to the file. Android/data game-cache.
• 🧹 Clean thumbnails folders in the gallery to free up space.

Cleaning the cache in Recovery mode

Recovery mode is a special diagnostic interface that boots separately from the main operating system. Use of this method is recommended if the phone is severely braking, does not turn on normally or you have just updated the firmware.Cache cleaning in this mode is the most deep and affects system partitions.

To enter Recovery mode, you need to turn off your smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, after which the phone will go to the menu with a black background and a few lines of text, control here with volume buttons, and the choice is with the power button.

Select Wipe Cache Partition from the menu. Don't confuse it with Wipe Data, which wipes your phone completely! Once confirmed, the system will clear the Dalvik system cache and temporary update files. This process can take several minutes.

💡

If you see a “No command” message with a fallen Android robot after logging in to Recovery, press the power button once, then press it again along with the volume button to make the menu appear.
