Xiaomi Deep Cleanup: How to Remove Garbage and Speed Up Your Phone

Modern Xiaomi smartphones, which are based on the shell MIUI or the new HyperOS, are famous for their functionality, but over time inevitably become overgrown with digital garbage. The accumulation of cache of applications, residual files after deleted programs and system logs leads to the fact that free space is rapidly running out, and the performance of the device decreases. Users often notice that the phone begins to “slow down”, loads apps longer or simply issues warnings about overflow of storage.

Competent cleaning is not just about removing random photos, but a comprehensive approach to maintaining the Android Operating System. Unlike the standard methods offered by the system itself, there are deeper and safer ways to free up space. In this guide, we will discuss proven methods that will help return your gadget to factory speed without risking losing important data or disrupting the stability of the firmware.

Before you start any manipulation, you should understand that system debris is an inevitable companion of active smartphone use. However, its volume can and should be controlled. Regular maintenance avoids critical situations when the phone stops receiving new messages or updating applications due to space shortage.

⚠️ Warning: Before conducting a deep cleanup, it is strongly recommended to back up important data in the Mi Cloud cloud storage or on your computer to eliminate the risk of accidental loss of information.

Use of the built-in "Security" application

The easiest and safest way to start servicing a device is to use the standard tools already preinstalled in every Xiaomi smartphone.The Security app is integrated deep into the system and has access to hidden memory areas that third-party programs often cannot reach without root rights.

When you run the app, you'll see a big green Cleanup button, and clicking on it starts scanning the cache, residual files, and junk. The system automatically detects files that can be deleted without harming the operating system. But be careful: sometimes algorithms can flag useful temporary files as trash that speed up the loading of commonly used applications.

For more fine-tuning, go to the Cleanup section inside the app, and Deep Cleanup features are available here, which analyzes the contents of download folders, screenshots, and large files. Analyzing large files allows you to quickly find videos or archives that take up gigabytes of space but have not been used by the owner for a long time.

Importantly, the built-in tool doesn’t always remove the cache of popular messengers like Telegram or WhatsApp, as they store data in secure directories, requiring manual approach or use of special features inside the messenger apps themselves.

⚠️ Note: Do not use the function "Memory Acceleration» (RAM) In modern versions of Android, the system effectively manages RAM itself, and forced closure of background processes can lead to increased battery consumption when they are restarted.

💡

Use the Cleanup widget on your desktop for quick access to the garbage removal function with one click, without going into the application settings.

Manual cleaning of cache and application data

The bulk of space is often social networks and instant messengers. Mechanical cleaning through settings allows you to remove the accumulated cache of specific programs without affecting their basic functionality. → Annexes → All applications.

When you select a heavy app (like YouTube, Instagram or VKontakte), click on Memory. Here you will see two buttons: Clear cache and Clear all data. Clear cache is secure and only deletes temporary files, speeding up the app, while Clear All Data will reset the app to a state immediately after installation, removing your logins, settings and correspondence.

Special attention should be paid to multimedia files in messengers. In Telegram, for example, you can set up automatic cache cleaning. Go to Settings → Data and memory → Memory Use and set a timer for autodelete (cache) for 3 days or a week, this will prevent the folder with media files from growing to giant sizes.

System applications also have their own cache, but you need to touch them with caution. Clearing the cache of the Google Play Store or Google Play Services can solve problems with downloading updates, but do not delete their data unnecessarily, as this can disrupt the synchronization of the account.

Storage analysis and removal of duplicates

Often users are unaware that half of their memory is occupied by duplicate photos, similar screenshots and forgotten downloads. You can use a built-in memory analyzer or third-party but proven utilities such as Files by Google to identify such files.

The MIUI file manager has a duplicate search function. Go to Files and select Images or Documents. The system will suggest sorting files by size or date. Removing duplicates is the fastest way to free up a few gigabytes without deleting anything really important.

Special attention should be paid to the Download folder. Browsers and instant messengers by default save all downloaded files there. Regular audit of this folder allows you to find installation files. APK from older versions of applications that are no longer needed, or PDF-documents that were viewed a year ago.

💡

Removing duplicates and forgotten downloads is often more effective than cleaning the system cache, as it gives a real increase in free space.

Working with Thumbnails folder and system garbage

One of the most voracious hidden folders on Android is.thumbnails, which is on the DCIM path, which stores thumbnails of your photos and videos for quick display in the gallery, and over time, this folder can reach 5–10 GB, especially if you often shoot high-resolution videos.

Deleting the contents of this folder is safe for your original photos.The system will automatically create new thumbnails as needed, but this will take some time and may temporarily increase the workload on the processor.To delete this folder, you will need a file manager with access to hidden files (turn on the display of hidden files in the Explorer settings).

It's also worth checking the folder. MIUI It's at the root of the internal memory, and it often accumulates error logs (debug_log) And backups of a voice recorder or a screen that you may have already saved to the cloud, and cleaning up those directories allows you to bring back precious megabytes.

Don’t forget the Tencent folder (if you use versions of messengers associated with that developer) or similar social media directories, which often contain hundreds of megabytes of automatically saved images from channels and chats you don’t need.

Cleaning through Developer Mode and ADB

For advanced users who want to get the most out of it, there is a USB debugging and computer-based cleaning method available that allows you to remove system debris that is not available even through root-right file managers, and this requires you to install ADB (Android Debug Bridge) on your PC.

The first step is to activate the developer mode. Go to Settings → About Phone and quickly click 7 times on the MIUI Version (or OS Version). After that, a new section will appear in the settings menu “Additional” → “Developers”.

Turn on USB debugging and connect your phone to your computer. You can use the command line to clear Dalwick's cache or temporary system files, and it's a powerful tool, but it requires care.

adb shell pm trim-caches 999999999

This command forcibly trims the cache of all applications to a specified limit (in bytes). By specifying a large number, you effectively force the system to delete all the accumulated cache. This is a safe operation, but it can temporarily slow down the launch of applications on the first start after cleaning.

⚠️ Attention: Use of teams ADB Incorrect commands can lead to deletion of system files or unstable operation of the device. Use this method only if you understand what you are doing.

Prevention and optimization of the system

To avoid going back to cleaning all the time, it’s important to put in place prevention. Automatically clearing the cache every 3 days through the built-in Security app is a best habit for the Xiaomi owner.It’s also worth turning off autoloading videos on social media and setting up mobile traffic limits for heavy apps.

Check the installed list regularly. If you haven't used it for more than 3 months, you'd better delete it. Many apps continue to run in the background, consuming resources and creating debris even if you're not using them.

Use cloud storage for photos and videos. Google Photos sync setting with Free Space allows you to automatically delete photos that are already stored in the cloud from your device, ensuring that your memory is never overflowing with media files.

💡

Regular prevention takes 2 minutes a week, but eliminates the need to do a complete phone reset due to memory shortages.

Compliance with these simple digital device hygiene rules will allow your Xiaomi smartphone to work quickly and steadily throughout its life.A clean system is the key to a long battery life and no lag in the interface.
