Memory Cleanup on Xiaomi: The Complete Guide

Modern Xiaomi smartphones running on the shell of MIUI or the new HyperOS have a huge functionality, but over time users inevitably face a lack of free space. When the built-in drive is full, the device starts to run slower, the cameras can not take a new picture, and the system gives annoying notifications. Understanding how to properly manage storage becomes a critical skill for each owner.

In this article, we will discuss how to delete excess files, clear the cache of applications and free precious gigabytes on your device. We will not rely on dubious third-party programs, but use built-in tools that are already in your phone, which will avoid the risk of infection with viruses and ensure that you do not damage system files.

Before we start taking radical steps, we need to understand the structure of the storage, which is divided into user and system memory, and we can not confuse them. A competent cleaning approach will allow you to extend the life of the gadget without having to buy a new model with a large amount of storage.

Analysis of vault occupancy

The first step should always be diagnostics. You don't have to guess what exactly takes up space, because Xiaomi's system provides the exact tools for this. Go to Settings → Memory to see the visualization of the data distribution, and here you will immediately see whether the photos, installed applications or system debris are to blame for the problem.

Often users do not realize that messengers like Telegram or WhatsApp can take up tens of gigabytes. Cache images, videos and voice messages are saved automatically, and deleting cache in such applications is the fastest way to get free space without losing important correspondence.

• 📱 Use the standard Security app for the initial scan.
• 📂 Check the download folders where forgotten installers often accumulate APK.
• 🗑️ Note the “Basket” section in the Gallery, which stores deleted photos for 30 days.

⚠️ Warning: Before a mass cleanup, always check the contents of the Downloads folder, which may contain important documents that you downloaded for work or study and safely forgot.

And you also have to look at offline maps on your navigators and music on streaming services, which are often dead weight for years, and if you rarely use navigation without the Internet, you can delete the maps and download them again if you need them.

Use of built-in cleaner

Every Xiaomi smartphone has a Security system app preinstalled, which is not just an antivirus, but a powerful combine to maintain the system, and Cleanup is the safest feature, because the algorithms know which files can be touched and which ones are responsible for the stability of the operating system.

When you start scanning, the system will suggest that you delete temporary files, remnants of deleted applications and advertising debris, which takes literally a minute, but you should not blindly trust the automation: after scanning, you should manually go through the proposed categories.

Pay special attention to the Big Files section. The cleaner often finds high-resolution videos that you've been shooting for months ago. Deleting such objects instantly frees up space. Remember, deleting files through this interface sends them to the bin, where they can be recovered within a month.

⚠️ Attention: Deep Cleaning may suggest removing application installation files (APK). Remove them only if you are sure that the programs are already installed and are working correctly.

Manual deletion of application data

The most voracious consumers of memory are social networks and instant messengers, and their mechanism is that they save every image they view, and to effectively free up memory, you need to go to the settings of a particular application: Settings → Applications → All applications.

Select a heavy app (like TikTok or Instagram) and click Memory. Here you will see two buttons: Clear cache and Clear everything. The first one deletes temporary data and is secure. The second one resets the app to the "just out of the store" state, removing logins and settings.

• 🚀 Clear the browser cache if you are an active Internet user.
• 🎵 Check the settings of offline mode in Spotify or Yandex.Music.
• 📸 Turn off auto-save storis in social media camera settings.
• 📦 Remove unused games that can weigh more than 2GB.

For Xiaomi users with extended rights or just attentive owners, it is useful to know about the folder. Android/data. In older versions of Android, it was freely available, but in newer versions of the OS, access is limited, but through the file manager, you can find folders of specific applications and delete their cache manually if standard methods do not help.

Working with multimedia and gallery

Photos and videos are the bulk of the data for most users. Duplicate images, series taken in "serial shooting" mode or just similar shots, take up space. Xiaomi Gallery has a smart album "Similar photos" that helps find and remove unnecessary options, leaving only the best.

Don't forget the screenshots. We often take screenshots to keep our map number or address in mind, and then forget about them. Find a Screenshots album and ruthlessly delete everything old. Also check out albums created by messengers (WhatsApp Images, Telegram Photos), as they often duplicate photos from the main gallery.

Using cloud services like Google Photos or Xiaomi Cloud, frees up space on your device. Google Photos’ “Free up space” automatically removes images that have already been successfully uploaded to the cloud from your device, a safe method to ensure your memories are safe.

Removal of system debris and residual files

When you delete apps in Android, you often have tails — empty folders with settings or temporary files — that you can use the built-in MIUI file manager to find. Click on the folder icon in the menu and select sorting by file type or date.

You should pay special attention to the Download folder, and it's where all the files from the Internet come in, PDF-You can use your documents and your images saved from social media, and cleaning this folder regularly is the golden rule of smartphone hygiene.

There's also a hidden folder called.thumbnails in the DCIM directory, which stores thumbnails of your photos for quick display in the gallery, and over time, this file can grow to several gigabytes, and it's safe to delete, and the system will create a new, smaller one the next time the gallery opens.

💡

To prevent the.thumbnails folder from growing back to giant sizes, some users create a file in the DCIM folder called.thumbnails (without extension) and block it from writing, which blocks the creation of thumbnail cache, but the gallery can run slower.

Radical measures: Resetting and formatting

If no methods are working and the memory is filling up on its own, maybe the system has a file table crash or the drive has broken sectors, in which case a full factory reset helps, a cardinal solution that will return the phone to the state of "out of the box."

Before the procedure, make sure to make a full backup of the data. Reset will delete absolutely everything: contacts, photos, apps and settings. Go to Settings → About phone → Reset → Erase all data.

⚠️ Warning: Make sure the battery is charged at least 50-60% interruption of the process due to battery discharge may result in the inability to turn on the device.

After reset, take your time to restore the backup of the apps right away. Try using a clean phone for a couple of days. If the memory remains stable, it means that the problem was in one of the installed applications or accumulated debris.

💡

Full reset is the only guaranteed means of removing all hidden system errors causing memory leaks, but requires full backup preparation.
