How to Clean Xiaomi Phone Properly: The Complete Guide

Xiaomi’s line of smartphones running MIUI shells or the new HyperOS are famous for their rich functionality, but over time, even the most powerful models can start to work slower. This is often due not to the wear of the processor, but to the accumulation of digital debris, memory fragmentation and improper work of background processes. If you notice that the interface slows down and applications open longer than usual, it’s time to do a general cleaning of the system.

There are many ways to optimize, ranging from built-in utilities to manually removing system logs. However, not all methods are equally useful: some can lead to loss of important data, while others can only lead to the appearance of improvement. In this article, we will discuss how to clean Xiaomi’s phone safely and efficiently using only proven tools and avoiding common errors that can turn a device into a brick.

Before you start taking action, you need to understand what exactly occupies space in your storage. Often users delete photos, forgetting that most of the memory is eating the messenger cache, remnants of remote applications and system error reports. A competent approach to cleaning will free up gigabytes of space without losing personal data.

Use of the built-in "Security" application

The first and most secure tool that is already installed on your device is the System Security app, which is designed specifically for the MIUI file system and knows which files can be deleted without risking OS stability. Launch the application and select Cleanup. The system will automatically analyze the storage and suggest that temporary files, installer packet residues and advertising debris be deleted.

But automatic cleaning is often superficial. For a deeper analysis, click on the Clear All button and then go to Deep Clean. Here you will see the categories of files that occupy the most space: videos, large files, unused applications. Be careful when browsing through document folders, as there may be important work files.

💡

Start a deep cleanup periodically immediately after installing large photo editing games or apps, as they create a lot of temporary files.

It is important to note that the function of cleaning duplicates in this application works quite correctly, but before mass removal of photos, it is better to double-check the selection manually. The system algorithm can count the same pictures taken in serial shooting mode or with a slight difference in exposure that you planned to leave.

• 🧹 Automatic analysis: Scanning the system for temporary files and cache.
• 🗑️ Removal APK: Finding application installation files that are no longer needed after installation.
• 📸 Duplicate Search: Identifying Repeated Photos and Videos to Free Place.
• 📦 Application Management: Tracking rarely used programs to remove them.

💡

The built-in Security application is the most reliable method of basic cleaning, which does not require the installation of third-party software and has access to system partitions.

Manual cleaning of cache and application data

Automatic utilities can’t always get to the cache of heavy apps like Telegram, WhatsApp or Instagram. These programs accumulate gigabytes of viewed images and videos that continue to be stored in memory even after you see them. To manually clean a Xiaomi phone, you need to go to the Settings menu → Apps → All apps.

In the list, find the most voracious app and click on it. Select Memory or Storage, where you will see the two main buttons: Clear and Delete Data. Using the Clear button is secure and only deletes temporary files. The Delete Data button will reset the app to a state immediately after installation, which will require re-authorization.

⚠️ Warning: Never use the Delete Data feature for system applications (e.g., Themes, Explorer, Security) or instant messengers unless you want to lose correspondence and settings without the possibility of recovery.

The browser cache can grow to several hundred megabytes if you often watch videos online or visit “heavy” sites. Each browser setting (Chrome, Mi Browser) has its own history and cache clearing section, which is often more efficient than the system.

Work with the storage and folder "Downloads"

One of the most common causes of memory loss is the Download folder, which users often download documents, installers, presentations and forget about, and over time, this folder becomes a digital “graveyard” of files that will never be used again, but take up precious space.

Open the standard file manager Explorer and go to the Downloads category. sort files by size or date. delete all.apk installation files, as once the application is installed, they become useless ballast. Also check social media folders (for example, Telegram often saves the received files to a separate directory inside internal memory).

For advanced users, it will be useful to know about hidden folders. Some applications create their directories at the root of internal memory. If you delete an application, but the folder with its name is left and empty (or contains logs), it can be safely deleted. However, be careful: deleting folders with Android, MIUI or Tencent names can disrupt the services.

Cleaning through the Engineering Menu and ADB

For users who want to get the most out of it, there are deeper cleaning methods, one of which is using an engineering menu. To get there, open the Phone app and type in the combination ##6485##. Here you can see detailed information about the battery and memory, but the cleaning functions here are limited and depend on the version of MIUI.

A more powerful tool is ADB (Android Debug Bridge) debugging, which by connecting your phone to your computer, you can remove system debris that is not available to the average user, by enabling Developer Mode (clicking seven times on the build number in the About menu) and activating USB Debugging.

adb shell pm clear com.android.browser

This command will completely clear the data and cache of a standard browser, and you can do the same with other system components knowing their batch names, but using ADB requires caution: an incorrect command can lead to unstable system operation or bootloop (cyclical reboot).

⚠️ Attention: Use of teams ADB To remove system applications (bloatware) may disrupt the work OTA-Google updates and services, only do this if you understand what a particular package is responsible for.

Delete residual files after deleting applications

The standard Android application removal procedure often leaves behind tails, folders with settings, cache and user data in shared memory. To clean Xiaomi’s phone properly, you need to regularly check the root directory of internal memory for folders with remote program names.

Use a file manager with hidden files. Pay attention to folders with names of remote games or utilities. Often there are cache cards (Android/obb folder or Android/data) that can take up hundreds of megabytes. In new versions of Android, access to the data folder is limited, but through the built-in Xiaomi Explorer, access to most user data is saved.

It's also worth checking the folder. MIUI/debug_log. It stores the logs of the system debugging, and if you're not a developer and you don't send error reports to Xiaomi, the contents of this folder can be painlessly deleted, freeing up space, and the system will create new logs as needed.

• 📂 Vendor folder: Often contains data from carriers that can be deleted if that carrier’s SIM card is not used.
• 🎮 Games folder: Some games create individual folders at the root that are not deleted when uninstalled.
• 📄 Office documents: Check folders from Word or PDF-Readers for the presence of old drafts.

Prevention and optimization of the system

Once you've been able to clean your Xiaomi phone of garbage, it's important to keep it in this state. Regular prevention takes less time than cleaning up once a year. Try not to install apps from unknown sources, as they often contain junk-generating advertising modules.

Enable the Advanced Cleanup feature in the Security app if it is available in your firmware version. It is also useful to reboot your smartphone periodically. Unlike the Turn-On mode, full Reboot re-initiates system processes and clears RAM more efficiently.

Remember to update the system. With newer versions of HyperOS and MIUI, Xiaomi is constantly improving its memory and file system algorithms. Older versions may have errors that lead to incorrect deletion of files or cache proliferation.
