How to Clean Up Your Memory on Xiaomi: The Complete Guide

Owners of Xiaomi, Redmi and Poco smartphones often face an unpleasant situation: the device starts to work slower, applications open with a delay, and the system notifies you of a lack of free space. This is because internal memory is overflowing not only with user photos and videos, but also with hidden system files, application cache and residual data from remote programs. MIUI HyperOS requires a certain amount of free space for the background processes to work properly.

Don't panic if you have a red space warning on your screen. There are effective methods to quickly free up gigabytes of space without losing important data. Memory cleaning is not just about removing photos, but about taking a holistic approach to managing your gadget's file system. In this article, we'll look at all the optimization options, from built-in tools to advanced methods for power users.

Before we start taking drastic measures, we need to understand what exactly is taking up space in your device. Often the culprits are messengers like Telegram or WhatsApp, who have been accumulating media files for years. Diagnosing the problem properly is half the solution. Let's look at how to do a deep cleanup and get the phone back to speed.

Analysis of occupied space through built-in tools

The first step is always to diagnose. The Android system in the MIUI shell provides enough detailed statistics about which parts of the storage are most loaded. To access this data, go to Settings → About Phone → Memory. Here you will see a pie chart where the color is highlighted apps, images, videos and system files.

Note the Other section, which is often where residual files and data that the system cannot automatically classify are hidden, and can be remote game databases or temporary update files, and this category needs careful analysis, because blindly deleting files from here can lead to unstable software.

💡

Use file search in Explorer by entering.apk or.log extensions to find old installers and error logs taking up space.

It is important to understand the difference between the amount of data an application takes up and the amount of data it has.Cache can grow to gigabytes, especially on social networks and browsers.Cache clearing is secure and doesn't delete your logins or game progress, unlike cleaning up Data, which will reset the application to a state immediately after installation.

Use of the “Security” and “Cleaning” application

Every Xiaomi smartphone has a Security system app preinstalled, which includes a powerful garbage removal tool. Launch it and press the Cleanup button. The scanner will analyze the device for temporary files, ad cache and empty folders. This is the fastest way to get a few hundred megabytes of free space in a couple of seconds.

However, standard cleaning is often superficial. For a deeper analysis, click on the garbage icon or go to the In-app Memory Cleanup section. Here, the system will suggest removing large files, duplicate photos and unused applications. Cleanup algorithms in new versions of HyperOS have become smarter and safer to remove system debris without affecting important configuration files.

⚠️ Warning: Be careful when using Deep Clean if you have important unsaved data in the clipboard or temporary folders of work applications. Always double-check the file list before confirming deletion.

Remember to update the Security app regularly through the GetApps store or Google Play. Developers are constantly improving the garbage file databases, allowing the utility to find new types of temporary data that previously went unnoticed.

Cleaning the cache of messengers and social networks

Memory consumption leaders are traditionally messengers. Telegram, WhatsApp and Viber store every photo and video viewed in the memory of the device. Over time, this “baggage” can take from 5 to 20 GB. In Telegram, the cleaning is done through Settings → Data and memory → Memory Use → Clear cache.

For WhatsApp, the procedure is a little more complicated, because the app stores backups locally. Go to Settings → Data and Storage → Storage Management. Here you will see a list of chats sorted by space, you can selectively remove media files from the heaviest dialogs without deleting the correspondence itself. This allows you to save text history, but free up space from videos and GIFs.

Social networks like VK or Instagram also aggressively cache content to quickly scrolle through the tape. These apps often don't have a "clean all" button in their settings, so you have to go to the phone's system settings: Apps → All apps → [social network name] → Memory → Clear cache. Regularly doing this procedure prevents the app from bloating.

Removal of duplicates and large files

Often users forget about downloaded files that have been in the Download folder for years. Old presentations, app installers (.apk), forgotten movies are all dead weight. Use the built-in File Explorer or Explorer, sort files by size, and ruthlessly delete what you no longer need.

Special attention should be paid to duplicate photos. When synchronized with the cloud or unsuccessfully imported from another device, you can create copies of images. There are special analyzer applications, but you can also use the built-in tools of Google Photos or the functions of the Xiaomi gallery that offer to find similar photos. Removing duplicates is the safest way to free up space.

The table below gives examples of file types that often take up space and recommendations for deleting them:

Transfer data to memory card and cloud

If internal memory is crowded, the logical solution is to transfer data to an external medium. Xiaomi smartphones support microSD memory cards. You can transfer photos, videos and music to them. To do this, select files in the Explorer, click Move and specify the path to the memory card. This will free the internal drive for the system to work.

An alternative to a physical map is cloud storage, Google Photos, Yandex.Disk or Mi Cloud allows you to upload media files to a server and delete them from your phone. Google Photos has a handy "Free Space" feature that automatically finds and deletes images already saved in the cloud, ideal for those who do not want to carry additional devices.

⚠️ Note: Before transferring data to a memory card, be sure to format it in an Android-compatible file system (usually exFAT or a file system). FAT32). An unformatted card may work slowly or not be determined by the phone.

Using the cloud requires a stable Internet connection. Make sure that the download is done via Wi-Fi so that you don’t exhaust the limits of mobile traffic. Set up automatic synchronization will allow you to forget about the problem of space shortage in the future, as new photos will immediately fly to the cloud.

Radical measures: Resetting to factory settings

If none of the above methods worked and the memory is filling up again quickly, it may be that critical errors have accumulated in the system or that fragmentation of the file system has reached a limit, in which case a full reset to the factory settings (Hard Reset) helps, this procedure will return the phone to the state of “out of the box” by removing absolutely all user data.

Before you reset, make sure to back up your phone completely. Use the Mi Cloud or make a local copy to your computer. Once reset, your phone will work like a new one, with maximum speed and full memory, and it's the most efficient, but also the most time-consuming way to solve the problem.

💡

Hard Reset is the only means that guarantees 100% memory cleansing from software debris, but requires a preliminary backup of data.

To do the reset, go to Settings → About Phone → Settings Reset → Erase all data. It takes 5 to 15 minutes. After the reboot, you have to reset the phone and install the apps. But the result is worth it: you get a clean system without hidden debris.
