How to effectively clean system memory on Xiaomi

Modern Xiaomi and Redmi smartphones offer huge amounts of built-in storage, but even 256 or 512 gigabytes can suddenly run out.Users often face a situation where the system reports a space shortage, blocking the installation of updates or launching heavy apps. Especially critical when it is the system partition responsible for the stability of the shell that is overflowing. MIUI or hyperos.

Overloading not only makes it impossible to take a new picture, but also leads to a noticeable decrease in the performance of the device. Garbage files, error logs and application cache accumulate for months, taking up precious space. In this article, we will discuss proven methods of freeing up space that will help return your gadget to its previous speed.

You don't have to be an expert in Android to do a basic cleaning, but there are hidden partitions and specific folders that not every owner knows about, and we'll look at both the regular cleanups and more advanced ways to remove system debris.

Analysis of the storage occupancy of built-in tools

Before you delete files, you need to understand what exactly takes up space. There's a handy tool in the MIUI shell for visualizing data. Go to Settings → Memory to see a detailed resource allocation diagram. The system will suggest clearing up the garbage, but often this analysis is superficial.

Notice the "Other" or "System Files" section, which is where gigabytes of data are often hidden that the standard cleaner ignores, which can be remnants of deleted applications, temporary update files, or messenger cache.

Use the built-in Security app for initial evaluation. Click on the Clean button, wait for the scan, and carefully review the proposed removal. Do not delete files that you are not sure about, especially if they are marked as system.

⚠️ Warning: Autoclearing can delete important logs or temporary files of running applications, resulting in them restarting or losing unsaved progress in games.

For a deeper analysis, you can use third-party utilities like DiskUsage, which show the memory card as blocks, which allows you to see the heaviest directories, but even a standard Xiaomi analyzer is usually enough to identify the main “eaters” of the place.

Cleaning the cache of applications and system services

The most effective way to free up space is to work with the app cache. Social media, browsers and streaming services accumulate huge amounts of temporary data. Go to Settings → Apps → All applications and select the heaviest programs.

Inside each app's menu, look for the "Storage" item, and here you'll see two buttons: "Clean" and "Clear cache." The second button is secure and only deletes temporary files. The first button will reset the app to a state immediately after installation, deleting your logins and settings.

• 📱 Telegram: often takes up tens of gigabytes due to saved photos and videos from channels.
• 🌐 Chrome: Cache of pages and cookies can grow to several gigabytes with active surfing.
• 🎵 Spotify/YouTube: Offline tracks and buffered videos take up space even after listening.
• 🛒 Marketplaces: Cache of products and images viewed is often not automatically deleted.

Special attention should be paid to MIUI Daemon or Analytics, which collect usage statistics and can inflate in size, and cleaning their cache through the application menu is a safe procedure that sometimes frees up to 1-2 GB.

💡

To quickly clear the cache of all applications, you can immediately use the command in the Security application, but manually checking heavy programs gives the best result.

Regularly cleaning messenger cache is a habit that prolongs the memory life of your smartphone. WhatsApp and Viber are better off using built-in storage management tools to remove old video files you don't remember anymore.

Removal of system debris and residual files

When you delete applications, you often have their tails in your memory, like empty folders or. You will need a file manager to access them, like Xiaomi’s standard Explorer or FX File Explorer. Turn on the hidden files in your Explorer settings.

At the root of internal memory, look for folders with names of remote games or programs. Android/data and Android/obb. It stores game data and app cache, and you need to remove content carefully, only if you're sure that the app is no longer needed.

System logs are often left behind after a new version of Android or MIUI is successfully installed. Searching for files with the.log extension or folders called log at the root of the system can reveal extra megabytes. However, only delete those whose creation date is older than a month.

Don't forget the Download folder. Many users have been storing.apk installation files, documents and pictures for years, and sorting by size in this directory often shows files that have long since become obsolete.

Work with the "System Files" and "Other" section

The mysterious "Other" category in the repository is often questionable, and the system records everything it can't classify: application data, system libraries, and cache, and it's completely impossible to clean this partition without losing data, but it can be reduced.

Often, the volume of "Other" is inflated by offline maps of navigators and music libraries. Check the settings of Yandex.Maps, Google Maps or 2GIS. Busy areas of cities can take 5-10 GB, which you may have forgotten about.

• 🗺️ Navigation: Delete maps of regions you haven’t been to in a while.
• 🎶 Music: check the cache of streaming services (Yandex.Music, VK Music).
• 📸 Gallery: A cart in the cloud or a local folder “Deleted” also takes up space.

Another source of system partition proliferation is the memory extension function, which means that if you use virtual RAM, the system reserves some permanent storage, and turning that off in settings (if available) will return space, but it can reduce multitasking.

In some cases, partition bloat is due to a media file indexing error. Rebooting the device or forcing the Media Service process to stop in the developer menu can trigger re-indexing and free up space.

Use of Developer Mode and ADB

For advanced users, a USB debugging method is available, which allows you to remove the system cache that is not available through the normal interface. To start, activate the developer mode by seven times clicking on the build number in Settings → About Phone.

In the Developer menu, turn on USB Debugging. Connect your phone to your computer and use the Android Debug Bridge (ADB) tool. The adb shell pm trim-caches command allows you to force the cache of all applications to a certain limit.

adb shell pm trim-caches 999999999

This command will try to free up nearly 1TB (conditionally) by deleting the app cache until it reaches a limit or clears everything it can, which is a safe operation, since it does not affect the user's personal data, only temporary files.

⚠️ Attention: Use ADB Do not remove system packages through the pm uninstall command unless you know exactly what they are intended for, which can lead to a “bootloop” (cyclic reboot).

You can also clear the cache of a particular application using ADB, knowing its batch name. For example, to clear the YouTube cache, the command will look like an adb shell pm clear com.google.android.youtube. This is a useful tool for combating bloated system services.

💡

ADB commands allow you to get to those parts of memory where the standard MIUI interface simply does not allow the user for security.

Radical measures: Resetting and formatting

If the software methods don't work and the memory keeps filling up on its own, it's possible that the file system is damaged or that a software bug has settled in the system, and then a complete factory reset helps.

Before the procedure, be sure to back up important data to the Mi Cloud or your computer. Reset will delete everything: contacts, photos, apps and settings. You can access the reset menu through Settings → About Phone → Reset.

Once reset, the phone will look like new. It's important to not restore all the apps from the backup in the first few hours, but to install them manually. Often, it's the old apps that are incompatible with the current version of Android that cause memory problems.

In rare cases, you need to flash your device with Wipe All Data cleaned through Recovery mode, a last resort in critical system errors where the phone doesn’t boot or constantly emits memory errors.

Prevention of memory overflow

To avoid reverting to the cleaning problem, implement simple digital device hygiene practices, automate the garbage removal process, and monitor smartphone usage habits.

Set up automatic cleaning in the Security app. In MIUI, you can set a schedule, for example, once a week at night, and also turn off auto-save incoming media in messengers, if this is not urgently necessary.

• 📅 Regularity: Check the Downloads folder once a month and delete unnecessary ones.
• ☁️ Cloud: Use Google Photos or Mi Cloud with Free Place».
• 🚫 Control: Do not install apps from unknown sources, they often contain advertising junk.

Use memory cards (if there is a slot) to store photos and videos, leaving internal memory exclusively for the system and applications. SD-map.

Following these simple guidelines will allow your Xiaomi to work fast and consistently for years to come. System memory is a resource that requires attention, but with the right approach, it will always be enough.
