Memory Cleanup in Xiaomi Phone: The Complete Guide

Many smartphone owners face the unfortunate situation of a device that starts to run slowly and notifications of space shortages appear at the most inopportune moment. If you have Xiaomi, the problem with crowded memory is solved quite quickly thanks to the built-in tools of the system. However, to get a real result, it is not enough just to press a button — it is important to understand which files take up space and how to safely delete excess.

In this article, we’ll look at not only standard cleaning methods, but also hidden features that will help free up gigabytes of space. You’ll learn how cache cleaning differs from deleting data from apps, and why memory card formatting is sometimes the only right solution. MIUI and the new HyperOS offer powerful tools that are often ignored by users.

Before you start taking any drastic measures, you need to diagnose the storage, which will allow you to understand what exactly eats up your volume: photos, messengers or system files, a competent approach to memory management will prolong the life of your gadget and eliminate the constant lag of the interface.

Analysis of vault occupancy

The first step to freeing up space is to analyze in detail what exactly takes up space on your device. Android, and in particular the MIUI shell, has a built-in analyzer that shows the distribution of memory by category. Don't rely only on the general numbers in the settings, as they often hide the real gigabyte eaters.

For an accurate picture, go to Settings → About Phone → Storage. Here you will see a color diagram where each sector is responsible for a specific type of content: apps, images, videos or system files. Often it turns out that the lion's share is occupied by social media cache or forgotten downloads from the browser.

📊 What takes up the most space in your Xiaomi?
Photographs and videos
Cash of messengers (Telegram, WhatsApp)
Installed games and applications
System files and so on.

It is important to pay attention to the category “Other” or “System Files”. If this partition inflates to inadequate size (more than 10-15 GB on an empty phone), this may indicate an accumulation of error logs or residual files after deleted programs.

Use of the built-in Security application

The easiest and safest way to clean up memory is to use the standard Security app, which is pre-installed on all Xiaomi smartphones.This tool is designed specifically for working with the MIUI and HyperOS file system, so the risk of removing important system components here is minimal.

Launch the app and click on the big green Cleanup button, and the system will scan and suggest that you delete temporary files, uninstall remnants, and junk, but don't blindly trust the automation: Before confirming an action, carefully review the file list, especially if there are documents or photos.

☑️ Check before complete cleaning

Done: 0 / 4

Inside the app, there's Deep Clean, which allows you to work with specific categories in more detail, and you can find duplicate photos, large files you haven't opened in a long time, and rarely used apps, and removing APK installation packages through this tool can instantly free up 1 to 5 GB of space.

⚠️ Attention: The “Cleanup” function in the Security app sometimes marks the cache of navigation maps (such as Yandex.Maps or Google Maps) as garbage. If you use offline maps, make sure you do not delete downloaded regions.

Clearing the cache and data messengers

Memory consumption leaders are traditionally messaging apps like Telegram, WhatsApp and Viber, which store every photo, video and voice message you receive in your phone’s memory, even if you’ve already viewed them and don’t need them. Standard cleaning often doesn’t affect that data, so you need to work inside the apps themselves.

Telegram handles the situation most elegantly thanks to the cloud structure. Go to Settings → Data and memory → Memory use and click Clear Cache. You can set up automatic cleaning, for example, once every 3 days or week, so that the phone never gets clogged with media files. This will not delete your correspondence, they will remain on the server.

WhatsApp is more complicated because it's locally stored. You go to Settings → Data and Storage → Storage Management. It'll show you the most spaced chats. Be careful: deleting media will also affect your email history if it wasn't stored separately in the cloud.

  • 📱 Open the settings of a specific messenger and find the section "Storage".
  • 🗑️ Use the built-in cache cleanup feature, rather than removing the app entirely.
  • ☁️ Set up auto-delete media files for group chats so they don’t save to the gallery.
  • 📂 Manually check folders in the file manager (for example, Android/media), Where to find heavy video.

Management of applications and their data

Apps accumulate data not only in cache form, but also in user profiles, temporary files and databases. Over time, the data folder can exceed the size of the application itself by a factor of dozens, as is the case with browsers, news aggregators and social networks.

To clear the data of a particular application, go to Settings → Apps → All apps. Select the desired program (for example, YouTube or Chrome) and click Memory. Here you will see two buttons: Clear cache and Clear all data. The first is secure and deletes only temporary files, the second will return the application to the “just after installation” state, deleting your logins and settings.

What is the difference between cache and application data?
Cache is temporary files (pictures, scripts) that speed up the application, but are not critical. They can be deleted safely. App data is your authorization, saved passwords, settings and local databases. Cleaning up the data will require re-entering the acca!> Special attention should be paid to system applications that you do not use. In Xiaomi, you can disable or remove preinstalled software (Mi Video, Mi Music, GetApps) if you do not use them. This will not only free up space, but also reduce the load on RAM and processor. Data Cleanup Type Security Recommended Cache Cleanup Frequency High Once a week APK File Deletion High No Data Loss As All Data Cleanup Average Full Application Reset When App Failures Remove Low Local Data Loss For Unused Software Photography and video services are the heaviest content stored on a smartphone. Modern cameras shoot in high resolution, and one minute of video in 4K can take up hundreds of megabytes of successful app Deletions Local Data Loss For unused software, It is likely that your phone is stored in the cloud, and that the same file is stored in the service. This allows you to access all your photos over the Internet without taking up your local memory. Remember to check the "Recently Deleted" folder in the gallery. The files you delete don't disappear permanently, but they're stored there for another 30 days, continuing to take up space. Cleaning This Cart Is The Fastest Way To Get Free Gigabytes Right Now. ⚠️ Before cleaning the folder "Recently deleted" or formatting the memory card, make sure that important photos are copied to the computer or to the cloud storage. Hidden folders and system debris In the Android file system, there are many hidden folders where applications reset logs, error reports and temporary data. On Xiaomi, these folders often have a prefix. (dot) at the beginning of the name or are in a deep nested system directory. To access them, you will need a file manager with permissions to access system folders (for example, MT Manager or built-in Explorer with the enabled display of hidden files. /Android/data, But be very careful: deleting unnecessary files here can cause programs to fail. 💡System debris often accumulates in log, temp, and cache folders inside application-specific directories. 2-3 GB of space, but it requires attention. MIUI/debug_log, If it exists on your device, it can store debugging logs that are created by the system when you crash, and if you're not a developer and you're not debugging your phone specifically, you don't need those files and you can delete them painlessly. If internal memory is not enough, the solution can be a microSD card. In modern models Xiaomi slot for "Simki" is often combined, so you have to choose: two SIM cards or one SIM card plus memory card. For multimedia, this is a great option. Once installed, it is recommended to format it as Portable Storage if you plan to move it to other devices, or as Internal Storage if you want to expand the memory for installing applications (although in newer versions of Android this feature is often hidden or works). For photos and videos, the first option is preferable. 💾 Use speed class memory cards U3 or V30 record 4K video. 🔄 Check the map for errors regularly through the Settings menu → Warehouse. 📸 Configure the camera so that photos and videos are saved immediately to the memory card. ⚡ Don't remove the memory card while your phone is running or recording video. Can you transfer all the apps to a memory card in Xiaomi? MIUI The ability to fully transfer applications (Adoptable Storage) is often blocked by the manufacturer or works incorrectly. The system allows you to transfer only part of the data (cache, media), but executable files (.apk) will remain in internal memory. Compulsory inclusion of this function through ADB-The commands can cause the phone to work in an unstable way. Why does the memory fill up quickly after cleaning? This is normal behavior of the system. Applications are constantly creating new temporary files, browser cache grows when you visit sites, and messengers receive new media. If memory fills up critically quickly (in a few hours), this may indicate a malfunction of a particular application that creates cyclic error logs, or viral activity. Is it safe to use third-party software-cliners (Clean Master and analogs)? Using aggressive third-party cliners on Xiaomi is not recommended. The built-in MIUI system itself effectively manages memory. Third-party applications are often the source of advertising, collect user data and can conflict with system optimization processes, causing the opposite effect of accelerated battery discharge and lags. What to do if the "Other" section takes 20 GB and do the next 2 folder, and try to fill in the "Other" section 1" and fill in the full loading of the application. Often this section hides the remnants of deleted games or corrupted databases that only see a full reset.
