How to effectively clean Xiaomi storage: from simple cache to system garbage

The situation when Xiaomi suddenly starts to work slower, and notifications about the shortage of space appear more often, is familiar to every owner of MIUI or HyperOS. The accumulation of temporary files, remnants of remote applications and “heavy” correspondence in instant messengers can turn a fast flagship into a clumsy device. Understanding how to clean Xiaomi storage correctly without deleting important data becomes a critical skill for extending the life of the device.

Many users make the mistake of relying solely on automated tools, or manually deleting system folders that can cause crashes. In this article, we will examine proven methods for freeing up gigabytes of space. We will look at the system’s regular tools, cloud services capabilities, and hidden debugging functions, which are often ignored.

Freeing up space is not just about removing photos, it's about working with the Android file system. Competent cleaning allows you to speed up the interface and prevent apps from hanging. Below are step-by-step instructions to help restore your smartphone to its previous sharpness.

Use of the built-in "Security" application

The first and most obvious step is to use a standard tool preinstalled in the MIUI shell. The Security app has deep access to system partitions, allowing it to find files that are invisible to third-party cleaners. It takes only a few seconds to start the scanning procedure, but the result can be impressive.

To get started, open the app and select Clean up. The system will analyze the application cache, installer packet residues and advertising debris. It is important to understand the difference between cache and data: cleaning the cache is safe and does not affect your logins or settings, whereas deleting the application data will reset it to a factory state.

⚠️ Note: When using Deep Clean, look carefully at the file list. The system may suggest that you delete old screenshots or documents you planned to save but forgot to move.

After the initial scan, you should go to the garbage cleanup section and manually check the categories Big Files and Unused Apps. Often this is where forgotten browser downloads or old WhatsApp videos that take up gigabytes hide, and using this tool at least once a week will prevent critical memory filling.

• 🗑️ Remove the cache of only those applications that you actively use, so as not to slow down their re-launch.
• 📦 Please note the section "Installation" APK", where the old versions of the program are often.
• 📸 Check the “Similar Photos” folder to remove duplicates of photos taken in serial shooting mode.

Analysis and removal of messenger data

The most voracious consumers of internal memory on Xiaomi smartphones are traditionally messengers. Telegram, WhatsApp and Viber tend to store all the media files viewed in the memory of the device by default. Without regular cleaning, these applications can take up from 5 to 20 GB of space, turning into a real “black box” of data.

Unlike manually sorting files through Explorer, the apps themselves offer built-in memory management tools. In Telegram, for example, the Settings path → Data and memory → Using memory allows you not only to clear the cache, but also set a limit on its size. This is the only way to ensure that the application does not grow uncontrollably in the future, automatically deleting old files when overflowing.

For WhatsApp, the situation is similar, but it requires a more careful approach. Go to Settings → Data and Storage → Storage Management. Here you will see a list of chats sorted by volume, often it turns out that half the space is occupied by videos from group chats that you haven't even opened.

Remember that clearing the messenger cache does not delete your correspondence if it is stored on the server (like in Telegram) or backed up. However, locally stored documents may disappear, so make sure that important files are saved in the cloud or on your computer before a radical clean.

Work with gallery and cloud storage

Media files are the second most important factor in Xiaomi’s storage occupancy. Modern cameras shoot in high resolution, and every minute of 4K video can take up hundreds of megabytes. Simply removing photos from a gallery is often not enough, as they move into the cart, continuing to occupy space.

An effective solution is to use cloud services like Google Photos or Mi Cloud. Google Photos’ “Free Space” automatically finds all images that have already been uploaded to the cloud and removes their local copy, which allows you to store thousands of photos in original quality, leaving only thumbnails on the phone to view.

Also worth noting is the recently deleted folder, which stores files for 30 days, taking up precious gigabytes, and for instant freeing up space, you can go to the albums, select this folder and click "Clean it all."

Don’t ignore the ability to compress photos before sending or storing them unless the original resolution is critical. There are optimization apps that reduce the weight of the photo without any apparent loss of quality, saving up to 40% of gallery space.

💡

Use the Compressed Photos feature in Google Photos or Mi Cloud settings to store originals in the cloud, and only leave optimized versions on your device, saving up to 70% of space.

Finding and Deleting Large Files and Duplicates

Often, the user does not even know what exactly is taking up space, which may contain forgotten movies, archives of games or installation files of updates, and MIUI has a built-in analyzer to search for them, but third-party tools can show a more detailed picture.

Use a file manager with disk analysis (e.g., Files by Google or Explorer built-in). Sort files by size. Often, you can find forgotten files several gigabytes in the root of internal memory or in the Download folder.

Duplication of files deserves special attention. With frequent synchronization or data failures, the same documents can be copied repeatedly. Deleting copies is a safe way to return space.

⚠️ Note: Be careful when deleting files with the.obb or.data extension in the Android folder. These are game cache files, and deleting them will cause game resources to reload the next time you run.

Also check the folder. MIUI → debug_log. In some cases, the system can start generating error reports in the loop, creating giant text files, which can be deleted if you're not debugging the system.

Cleaning through Developer Mode and ADB

For advanced users who don’t have enough regular methods, there is a possibility of cleaning through debugging via USB, which allows you to remove system debris that is not available to the average user, but requires a connection to a computer.

First, activate Developer Mode. Go to Settings → About Phone and press MIUI seven times. Then, in the advanced settings, turn on "Debugging USB." Once you connect your phone to your PC, you can use ADB commands to clean Dalvik cache or temporary system files.

adb shell pm trim-caches 999999999

This command forces the aggressively trim system to cache all applications, freeing up space, but it is only worth using when there is an acute shortage of space, since after that, applications can start slightly slower than usual on the first start.

Another powerful tool is the team to clean logs, which can grow to giant sizes in the event of a system failure:

adb logcat -c

Using ADB requires care. Incorrect deletion of system files can lead to unstable Xiaomi.Always check the file path before applying the deletion command.

Prevention of memory overflow

To keep the question of how to clean Xiaomi's storage from getting up every day, you need to have a prevention system in place. Regularity is the key to clean memory. Allocate 5 minutes a week to check uploaded files and messenger cache.

Turn off automatic media storage in the gallery for all chats in messengers except a select few. This will prevent the gallery from clogging with postcards and random pictures from work chats. Set up auto-save to the cloud so that photos don't accumulate locally.

• 🔄 Make a rule: “I took a screenshot – a day later I checked if it was necessary".
• 📵 Turn off autoloading videos on social media when using mobile data.
• 🗑️ Remove apps that haven’t been used for more than a month.

Following these simple rules will allow your Xiaomi to run fast and consistently for years to come.Memory is a resource that requires management, not just passive storage.

💡

The key to clean memory is to keep the garbage from accumulating, not to fight it when the phone is already barely working. Set up automatic cleaning and sleep well.
