What is the memory of Xiaomi: deep analysis and cleaning

The situation when Xiaomi smartphone suddenly starts to work slower and the system persistently reports a lack of space, familiar to many users. owners of devices often wonder what exactly is clogged memory, because after buying gigabytes seemed limitless. Android file system is designed so that over time acquires a huge amount of temporary data that is not deleted automatically.

The main “eaters” of space are usually multimedia files from messengers and cache installed applications. MIUI or HyperOS system also takes a significant amount of space for its stable operation, but often this balance is disturbed by user content. Understanding the structure of folders will help you effectively manage free space without deleting important data.

In this article, we will look at where gigabytes go, how to distinguish system files from garbage, and what tools are best used for diagnostics. A competent approach to the file manager will make room faster than standard cleaning tools.

System Files and MIUI Data

The first thing that a user sees when analyzing storage is the System section, which in Xiaomi smartphones includes not only the operating system itself, but also preinstalled applications that cannot be removed by standard methods. The System partition often inflates after major firmware updates, as older versions of components can remain in backups.

Special attention should be paid to /data/local/tmp and system update cache, which can sometimes get stuck in files that are several gigabytes in size from a failed attempt to update Android, their removal is safe, but requires root access rights or the use of special utilities for cleaning.

⚠️ Warning: Never delete files from the root folders of the system manually without understanding their purpose.This can lead to a cyclical restart of the device or loss of functionality.

You can use the built-in Security app to analyze system debris, but it doesn't always show the full picture. A deeper analysis is possible through a computer with an ADB connection, which allows you to see hidden logs and error dumps.

Social media and messenger cache

Social media and instant messengers are the undisputed leaders in memory consumption. Telegram, WhatsApp and Viber store every photo, video and voice message viewed in local storage, and over time, this data turns into gigabytes of “digital fat” that slows down the smartphone.

The largest file size is usually the Android/media/org.telegram.messenger folder, which stores all downloaded media files, and the feature of these applications is that even after deleting the chat, files can remain on the disk if the auto-clean function was not enabled.

• 📱 Telegram: Stores cache of channels and groups you haven’t even read unless they’re turned off in your settings.
• 💬 WhatsApp: Creates video backups to a local folder by duplicating cloud backups.
• 🎵 TikTok: caches the viewed videos for quick scrolling, taking up a huge space.

It is recommended that you check the settings of each messenger regularly, for example, in Telegram you can set a cache size limit so that the application itself deletes old files, which is the most effective way to combat overflow.

DCIM folder analysis and screenshots

The standard DCIM folder is designed for photos and video from the camera, but often it overflows with redundant content: screenshots, high-resolution screen recordings and series of pictures in Pro mode take hundreds of megabytes. Users often forget to delete failed frames or long videos.

Screenshots and Video Recorder are also worth noting: if you often take screenshots of correspondence or instructions, they accumulate dead weight. 4K video at 60 FPS can weigh 400 MB per minute of recording, which quickly eats up the free space.

Use the Recycle Bin feature in the Gallery, but remember to clean it too. Files in the Recycle Bin continue to take up disk space for 30 days unless you change the storage settings of the remote one.

Offline content and downloads

Streaming services and navigators allow you to save maps and music to work without the Internet. Apps like Spotify, Yandex Music, Google Maps or 2GIS create large databases, and users often forget that they have downloaded a map of an entire region or hundreds of tracks.

The Download folder is another source of garbage, and it's left with APK installation files, documents, presentations, and archives that you needed once, and the default browsers are saving everything you downloaded here without asking permission.

💡

Use the “Cleaning” widget on your desktop MIUI To quickly access the download folder, set up automatic deletion. APK-files after installing applications.

Check the offline settings in the navigators. Sometimes the map of the city can take 2-3 GB. If you are not planning a trip, this information is better deleted and re-uploaded if necessary.

Duplicates and hidden folders

When you use a smartphone, you often create duplicate files, which is when you sync with the cloud, send files over Bluetooth or Mi Share, and edit photos, and the system can save a copy of the image after each edit.

Hidden folders that start from a dot (like.cache) can also grow. Some applications create temporary repositories there and forget to clean them.

⚠️ Warning: Before deleting files from hidden folders, make sure they don't contain your app settings.

There are special take-down applications that scan the storage by hash sums of files, which allows you to find exactly the same files, even if they are called differently and lie in different directories.

Deep cleaning tools

Standard tools may not be enough to effectively address space shortages, and advanced users use tools like DiskUsage or Storage Analyzer, and they visualize the file system as a diagram, where you can immediately see which file takes up the most space.

The built-in Security app in MIUI has a Cleanup feature, but it often acts superficially. For deep cleaning, you can use the Advanced Cleanup mode, which finds large files, unused applications and remnants of remote software.

adb shell pm list packages -f

This team is through ADB list all the packages that are installed with the paths to them APK-files, which helps to find system debris left by remote applications. ADB caution.

💡

Storage visualization is the fastest way to find heavy files, and diagrams show the actual amount of space you're taking up, unlike a standard folder list.

Prevention of memory overflow

To avoid the problem of “what is clogged” regularly, you need to implement the habit of periodic cleaning. Automate the process: set up a cache cleaning once a week and transfer photos to the cloud immediately after shooting. Cloud services like Google Photos or Mi Cloud allow you to store originals on the network, leaving only compressed copies on the device.

Keep an eye out for app updates. Often developers optimize code and reduce the cache size of new versions, and also don’t install apps from unknown sources, as they may contain hidden miners or ad modules that fill up memory.
