How to Clean Xiaomi Phone Manually: The Complete Guide

Xiaomi’s Android-based mobile devices and MIUI shell are notorious for their functionality, but they inevitably become digital garbage over time. The accumulation of temporary files, residual data from remote applications and sprawling cache can significantly slow down the gadget, cause interface friezes and a lack of free space. Users often wonder how to effectively and safely free up space without deleting important personal data.

Unlike third-party clinching applications, manual cleaning allows you to precisely control the process and ensures that the desired files are not destroyed by an algorithm error. Manual cleaning provides a complete understanding of the structure of the file system of your smartphone. In this material, we will discuss in detail all the steps of manual cleaning, from standard system tools to deep analysis of folders through the file manager.

Before we get into action, it’s worth noting that regular maintenance of the device prolongs its life. Systematic deletion of the messenger cache can free up to 5-10 GB of memory monthly. Let’s take a step-by-step algorithm that will help restore your Xiaomi to its former friction.

Use of the built-in "Security" application

The first and simplest tool you already have is the standard Security app, which is preinstalled on all Xiaomi and Redmi smartphones and contains basic functionality to clean the system. Launch the app and select Cleanup. The system will automatically analyze the device for temporary files, advertising debris and residues of app installation.

Once you scan, you'll see a list of categories that take up space, usually system cache, app cache, and other debris. By clicking Clear, you'll delete the secure temporary data. However, this method is superficial and often does not affect heavy messenger files or error logs.

It's important to understand the difference between cache and application data. Cache can be removed freely, it's recreated when programs are running. App data is your correspondence, game progress and settings. When manually cleaning through application settings, be extremely careful not to reset authorization in important services.

💡

Use the Deep Clean feature in the Security app only after previewing files so that important documents are not accidentally deleted.

Analysis of the storage through system settings

To control your memory in more detail, you need to go to system settings. Find the About Phone section and select Memory (or Storage depending on the version of MIUI), and here you can see the visualization of occupied space, broken down into categories: applications, images, videos, documents and system files.

Click on the App category to see a list of all installed programs sorted by size. Often it turns out that social networks and instant messengers eat most of the memory. By selecting a specific application, such as Telegram or Viber, you can go to the Warehouse menu and select the option Clear Cache.

• 📱 Social networks: often store gigabytes of viewed photos and videos in cache.
• 🎵 Streaming services: Spotify or Yandex.Music can save tracks for offline listening.
• 🎮 Games: Cache of graphics and resources can take several gigabytes.

The same menu is available for management. SD-The system may suggest that some applications be moved to an external drive, which will free up internal memory, but it is worth remembering that the speed of applications from the memory card may be lower than from internal storage.

💡

A system memory analyzer is the most reliable way to find “heavy” applications that you haven’t used in a long time, but that continue to take up space.

Working with a file manager and removing duplicates

The standard Explorer Explorer (or File Manager) allows you to work with the file system directly. Go to the Analyzer or Categories section. Here you can find large files, duplicate images and rarely used documents. The function of finding duplicates is especially useful, since users often take multiple identical pictures or download files again.

Notice the Download folder. This is where the main chaos accumulates: the installations. APK-files, stored images from browsers and temporary documents. Regular sorting of this directory is the key to the purity of the smartphone. Delete files with the.apk extension after installing programs, they are no longer needed.

⚠️ Note: When deleting files through Explorer, make sure they are not system.Do not touch folders with Android names, MIUI, System or Data if you are not sure about its contents at 100%.

It's also worth checking messenger folders inside internal memory, for example, in the MIUI directory -> gallery -> cloud, you can store thumbnails, and in the folders of specific applications - saved statuses or media files, manually checking allows you to delete exactly what you do not need, unlike automatic scripts.

Cleaning the cache of messengers and social networks

Messengers are the main memory consumers on a modern smartphone. In Telegram, for example, cache accumulates automatically. Go to Settings -> Data and memory -> Memory Use. Here you can clear the cache with a single click and set a limit on its size or media storage period.

On WhatsApp, the situation is similar, but file management is often more convenient through the application's built-in file manager. Go to Settings -> Data and Storage -> Storage Management. The system will show files larger than 5MB and allow them to be selectively deleted. This is more efficient than blindly cleaning the entire cache.

Social networks like Instagram or VK also cache the feeds and Stories viewed. These apps often have a "Clear Cache" option in their settings. If there is no such option, you will have to use the system method through the phone Settings -> Apps described above. This will free up a significant amount of space.

• 🗑️ Telegram: cache can be cleaned safely, the history of correspondence will not suffer.
• 📸 Instagram: Clearing the cache will require re-entering your account.
• 💬 WhatsApp: Delete large video files via the storage management menu.

Removal of system debris and residual files

When applications are removed, they often have their tails in the system, folders with settings, logs, and time data, and you can find them in the root directory of internal memory, look for folders with the names of remote programs or developers, and if you're sure that the program is deleted, you can delete the corresponding folder.

Also worth looking at is the.thumbnails folder (may be hidden), which stores thumbnails of your gallery photos, and over time, this file can grow to giant sizes even if the original photos have already been deleted, and cleaning up this folder will speed up the gallery.

Some users are using the ADB-commands to clean system partitions in depth, but that requires a PC connection and skills. Most of the time, manual file manager work is enough. The rule is not to delete files you don't know what they're supposed to be.

⚠️ Note: Files with.obb extension in folder Android/obb They contain game data (graphics, sounds) and deleting it will require you to re-download game data when you start up.

Prevention and optimization of memory

To keep the question of how to clean your phone from getting too often, you need to implement simple smartphone habits: check the Downloads folder regularly and delete the unnecessary ones; disable auto-save media from messengers to the gallery if you don’t need to.

Use cloud storage to archive photos and videos. Services like Google Photos or Yandex.Disk allow you to free up space on your device by storing copies in the cloud. Xiaomi also runs Mi Cloud, which can automatically clean the gallery of already uploaded photos.

Periodic reboots also help clear RAM and complete the hanging processes that can consume resources. Just do it once every few days. Following these simple rules will allow your Xiaomi to work quickly and consistently throughout its life.

💡

The best prevention of memory deficiency is conscious storage of files and regular monitoring of auto-save settings in messengers.
