How to Clean Up Internal Memory on Xiaomi Phone: From Basic Settings to System Files

Modern smartphones Xiaomi, Redmi and POCO are equipped with huge amounts of storage, but even 256 or 512 gigabytes are filled with time. the Android operating system in conjunction with the shell MIUI or the new HyperOS actively accumulate temporary files, app cache and error logs that are invisible to the user occupy precious space. When internal memory is overflowing, the device begins to work slower, and photos cease to be stored in the gallery.

There are many ways to make room, from standard cleaning tools to manually removing system debris through a computer. It is important to understand the difference between useful data that cannot be touched and digital junk that only slows down the gadget. In this article, we will discuss all proven methods of optimization of storage that will help return the performance of your device without losing important information.

You don't have to go through radical measures like resetting your settings completely. You can clean up your file system and you can avoid having to reinstall your operating system, and let's look at the steps you need to take to get the most out of it.

Analysis of storage occupancy and search for large files

Before you delete anything, you need to understand what exactly takes up space on your drive. Xiaomi's built-in tools provide quite informative statistics, but for deep analysis, it is better to use specialized utilities or an integrated analyzer. Go to the Settings menu β†’ About Phone β†’ Storage to see the basic distribution of data by category.

It often turns out that the lion’s share of the volume is not installed applications, but media files from messengers. Telegram and WhatsApp by default store all the photos and videos you viewed in the memory of the device. If you are in dozens of channels and chat rooms, in a year there can accumulate up to 50 gigabytes of garbage, which is formally considered important data of the application.

For a more detailed look at folder structure, you can use a file manager, and look at DCIM, Download, and Android/data folders, which are where forgotten videos, APK installation files, and streaming cache are most often hidden, and removing unnecessary copies from those directories gives instant results.

It is worth mentioning the MIUI/Gallery/cloud/cache folder, where thumbnails of deleted photos can be stored. They are safe to clean, but after the procedure, it may take time to re-generate the previews in the gallery, and regular monitoring of these partitions will help maintain order in the file system.

Use of the built-in "Security" application

Each Xiaomi smartphone has a security system app preinstalled, which includes a powerful tool for cleaning garbage. Despite the fact that many experienced users criticize it for intrusiveness, the algorithms of this module are well optimized for the structure of MIUI files. Launching the Cleanup feature allows you to safely delete temporary files, remnants of remote applications and advertising cache.

Inside the app, there's a Deep Clean section that scans the device more thoroughly, and you can find duplicate photos, large files you don't use, and unused apps, and the system itself will suggest removing installer packets left over from software updates, which often frees up a few gigabytes.

It is important to be careful when using the function "Memory Acceleration" (RAM), The release of RAM does not add space to the internal drive, although it can temporarily speed up the interface. PAM (memory).

⚠️ Note: When using Deep Clean, carefully read which files are tagged for deletion. Sometimes the system may suggest removing the cache of navigation maps, which will require you to re-download maps of regions the next time you run the navigator, which will waste traffic and time.

Clearing the cache and data messengers

Messengers are the main devours of free memory on Android smartphones. The mechanism of their work involves saving all media files locally for quick access. On Telegram, the storage settings are located in the Settings menu β†’ Data and memory β†’ Memory Use. Here you can set a cache limit or completely clean it without losing correspondence, since it is stored in the cloud.

WhatsApp is more complicated, as the history of correspondence and media files are often stored locally. To clean, go to Settings β†’ Data and Storage β†’ Storage Management. The system will show files larger than 5 MB and allow you to select the chats that occupy the most space. Deleting media from a particular chat will not affect text correspondence.

Don't forget to cache other social networks like VK, Instagram or TikTok. These apps save a huge amount of videos and images you've watched. Each app's settings have a "Clear Cache" button in the Apps section (in your phone settings). Clicking "Erase Data" will log out and delete the saved drafts, so use this option carefully.

Secret folder.thumbnails
The Android/data/com.miui.gallery/cache/.thumbnails system folder often stores thumbnails of deleted photos, which can weigh up to several gigabytes, can be safely deleted through the file manager, but can be recreated over time.

Regularly cleaning the messenger cache is the most efficient way to keep the space free without losing important data. Set up automatic cache cleaning in the applications themselves, if such a feature is available, so that the process takes place without your participation.

Over the years, the gallery has accumulated thousands of images, including many defective, repetitive or simply forgotten screenshots. The built-in MIUI gallery has a duplicate search function, but third-party apps do this better by finding similar images (serial shooting) that can be replaced with one better shot.

Notice the Recycle Bin folder in the gallery, where deleted photos don't disappear, but are stored for 30 days, and they continue to occupy space, and cleaning the Recycle Bin is a must if you need to make room, and also check the Screenshot and Recents folder, which often contains forgotten images.

Using cloud services like Google Photos or Xiaomi Cloud, frees up space on the device by leaving high-quality photos on the Internet. Google Photos’ β€œFree space” feature automatically removes photos from the phone that have already been successfully uploaded to the cloud.

Working with system files and Android folder

The Android folder at the root of the internal drive is the most questionable, with data and obb subfolders, which store app data and game cache, and removing the contents of the obb folder will cause heavy games to stop running and require a re-jump of resources, but old folders from already remote games can and should be eliminated.

Newer versions of Android have limited access to the Android/data folder, the Explorer may not show its contents or prevent deletion. This directory often requires connecting the phone to a computer or using special file managers with access rights. Be extremely careful: removing a random file from the system service can lead to errors in the interface.

It’s also worth checking out the Xiaomi/euclid folder or the like, which can create some system processes for temporary data storage. If you don’t use certain Google or Facebook services, their cache in this directory can be cleared through the application settings, but manually touching files inside the Android folder without understanding their purpose is not recommended.

πŸ’‘

If you delete an app but it's still in Android/data, don't rush to manually delete it. Some system services may require it when you re-install it. You'd better trust the residue cleanup to the built-in storage analyzer.

⚠️ Warning: Never delete folders with system service names such as com.android.providers.media.module or com.miui.home.This will cause a gallery or desktop malfunction, up to the need to completely reset your phone.

Transfer data to memory card and cloud

If your Redmi or Xiaomi model supports microSD card installation, this is the perfect way to relieve internal memory. Modern shells allow you to set up automatic photo and video saving immediately to an external card. SD-map".

The memory card can also be used as an extension of internal memory for installing applications, although in recent versions of Android this feature (Adoptable Storage) is often hidden or unstable. It is more reliable to use it as a media storage.

Cloud storage is a modern alternative to physical maps. Services like Yandex.Disk, Google Drive, or Mi Cloud offer automatic uploading of photos. By setting up sync only over Wi-Fi, you can store archives for several years without worrying about the lack of gigabytes on the device itself.

πŸ’‘

Combining cloud storage for photos and a physical memory card for media files is the most effective strategy for smartphones with a small amount of internal memory.

Remember that applications running from a memory card can be slower than internal storage, so system applications and heavy games are better left on the main memory, and personal archives are removed from it.

Radical measures: Resetting and formatting

When software methods don't work and the memory fills up on its own right after cleaning, it's possible that the file system is damaged or a virus miner has started in the system, in which case a full factory reset helps, and before this procedure, be sure to back up all the important data, because formatting will delete everything irrevocably.

Resets are done through Settings β†’ Phone β†’ Settings β†’ Erase all data. This process will put the phone back out of the box by removing all the digital debris, hidden logs and registry errors that have accumulated over the years. This often works wonders with the speed of an old device.

If even after the reset, the problem returns instantly, it may indicate physical wear of flash memory, in which case the drive goes into read-only mode or begins to display the amount of free space incorrectly, only replacing the memory module at the service center or buying a new device will help.

Why does the memory fill up after cleaning?
This is often due to background processes that cache content (such as social media feeds) or system logs that are not automatically cleared, and it may also be due to a malfunction of a particular application that creates cyclic error files.
Is it safe to delete files from the Android/obb folder?
You can only delete folders from games and applications that you have already deleted or do not plan to use. If you delete the active game folder, it will stop running and require re-uploading data (often several gigabytes).
How to clear the cache of the system application "Google Play Services"?
Go to Settings β†’ Apps β†’ All Apps β†’ Find Google Play Services β†’ Storage β†’ Clear Cache. This often solves sync issues and frees up space.
Can a memory cleanup damage your phone?
The risk is only when you manually delete system files in Android/data folders or system directories through root rights, which can lead to unstable operating systems.
