Cleaner on Xiaomi: what is this application and how to use it

Owners of Mi and Redmi smartphones often notice a system application called Cleaner in the list of installed programs. Many users wonder what kind of tool this is and whether it is really necessary for the stable operation of the device. In fact, it is a regular utility from the developers of MIUI, designed to free RAM and delete temporary files that accumulate during operation of the gadget.

Unlike third-party counterparts, which are often overloaded with advertising and require unnecessary permissions, the built-in Security Cleaner is integrated deep into the MIUI shell. It has access to system logs and caches that are hidden from ordinary file managers. Using the native application ensures that the cleanup will be safe and will not affect important system processes.

But the app's functionality goes beyond freeing up space, and it's also hidden tools for managing startups, analyzing large files, and even antivirus testing, and understanding how to set up the tool correctly will help extend battery life and speed up the interface without having to buy an expensive flagship.

The main purpose and functionality of the application

The main task of the application is to optimize the resources of the device in real time. When you start cleaning, the system scans the partitions where temporary application data, remnants of deleted programs and error logs are stored. Xiaomi Cleaner analyzes this data and suggests removing what does not affect the operation of the OS, but takes up precious gigabytes.

It's important to understand the difference between cache and important data. Cache is a temporary file that speeds up the loading of frequently visited pages or interface elements. Deleting it is safe, but it can lead to a slightly longer loading time the next time you log in to an application, re-forming the necessary files. Cache cleaning is useful when an application is not working correctly or takes up an abnormally large amount of space.

The software is constantly updated, with the latest versions of MIUI and HyperOS adding smart algorithms that recommend removing duplicate photos, screenshots and forgotten downloads, and it can tell you which files you are most likely to stop using based on the statistics of how they are opened.

💡

Don’t use memory acceleration all the time. In modern Android versions, the system manages RAM efficiently, and forced process unloading can only increase battery consumption to restart it.

Users often confuse storage cleaning and RAM cleaning. In the Cleaner app, these functions can be combined or separated depending on the firmware version. Storage deletes files, and RAM (Memory) closes background processes.

Instructions for proper cleaning of the smartphone

To get the most out of the utility, you need to clean it sequentially, don't just rely on the "Clean" button, which removes only obvious debris, and go through several steps manually to make sure that it gets into the cart.

Start a standard scan first. The app will quickly scan the main folders and prompt you to delete "junk." These are usually secure files, but experienced users are advised to click on "Junk Cleanup" and carefully review the list before confirming.

Pay special attention to the large file section, often with forgotten movies, archives or WhatsApp backups that weigh gigabytes, removing such objects is the fastest way to free up space, and checking the download folder, which often includes installations, is also worth checking. APK-Files that are no longer needed after installing programs.

⚠️ Before mass cleaning the Download folder, make sure that there are no important documents, checks or saved tickets. the application may mark them as unused if you have not opened these files in a long time.

For social networks such as Telegram or Viber, the built-in cleaner may not be effective enough, since messengers store media files in specific folders, it is better to use built-in cleaning tools inside the applications themselves or specialized sections in storage settings.

Storage analysis and duplicate search

One of the most useful features is finding duplicate files. A smartphone camera sometimes takes serial pictures, or you may have accidentally saved a copy of a photo when editing. The Cleaner app can find duplicates by comparing not only names but also the contents of files.

In the Photos section, you can see groups of similar images, and the system will suggest leaving the best frame (usually marked with a tick or an asterisk), and sending the rest to be deleted, which is especially true for users who take many pictures in Serial mode.

• 📸 Serial photos: the app groupes the frames taken, offering to choose one.
• 📄 Documents: Copy search PDF or DOC filename.
• 🎵 Music and video: detecting tracks or videos downloaded multiple times.

In addition to duplicates, you should also look at the "Unused Applications" section, which shows programs you haven't run for more than 30 or 60 days, and it's a great way to get rid of software that's just taking up space and maybe collecting background data.

Managing Autoboot and Background Processes

The built-in tool allows you to control which applications run with the operating system. Excessive programs in autoboot can slow down the phone's turn on and consume battery power in standby mode.

To get into this section, you need to go to the security settings and find "Allows" or "Outstart." Here you will see a list of all installed programs. It is recommended to leave autoboot on only messengers (to receive notifications) and alarms.

Turning off autoplay for games and rarely used utilities is the right step to optimize. However, be careful: if you turn off system services or drivers, the phone may start to work unstable. Focus on names: if you don't know what the process is for, it's better not to touch it or Google the name beforehand.

The dangers of third-party clinching applications

There are thousands of apps on Google Play with names like "Super Cleaner," "Fast Cleaner," and so on, and many users install them without realizing the risks, and unlike the regular Xiaomi Cleaner, third-party programs often work aggressively and intrusively.

The main problem with these apps is advertising, which can display full-screen banners at the most inopportune moment, blocking the interface of other programs, and they often require access to contacts, geolocation and a call list, which is a direct violation of privacy.

⚠️ Attention: Third-party cliners can force system processes to close, leading to an interface reboot or smartphone freeze. MIUI They work softer and take into account the specifics of the shell.

Another danger is false reports, where an app can claim to have found 5GB of viruses or junk, when they are actually important system files, and they are designed to scare users into buying a premium version or installing more adware.

If you do use third-party software, carefully check the permissions when installing. Refuse access to personal data if the memory cleanup application requires the right to read SMS or call.

Systemic garbage: myths and reality

There is a persistent myth that the phone needs to be cleaned of “system garbage” every day. In reality, modern Android file systems (like F2FS or ext4) are great at managing data on their own. Excessive cleaning can even hurt, forcing the processor to re-index files.

What is real system debris? These are error logs that are created when applications crash, and temporary update files. MIUI Security automatically removes most of this debris when you reboot or during nighttime optimization.

Avoid using "radical" cleaning techniques, such as manually removing folders with Android/data prefixes without understanding the structure, which can lead to loss of progress in games or settings in applications. Trust automation where possible.

💡

The optimal cleaning frequency with built-in means is once every 1-2 weeks or when the system itself reports a shortage of space.
