How to Clean Memory on Xiaomi Phone: The Complete Guide

Xiaomi and Redmi are famous for their performance, but over time, even the most powerful processor can start to “think” because of overflowing internal drive, when the system does not have enough space for temporary files and normal cache. Users often notice that after updating applications or actively shooting 4K video, the phone starts to work slower.

Memory cleaning is not just about removing old photos, but a comprehensive approach to maintaining the MIUI or HyperOS file system. Unlike other manufacturers, Xiaomi shells have their own garbage file handling features that require a specific approach to effectively delete. Ignoring this procedure can lead to serious interface lags.

In this article, we will look at all available methods of freeing up space, from built-in tools to advanced techniques for power users, you will learn which folders can be deleted without fear and which can not be touched categorically. Proper cleaning will prolong the life of your device and return it to its previous response speed.

Analysis of vault occupancy

Before you start taking any radical action, you need to understand what exactly takes up precious gigabytes. Modern versions of the MIUI shell have an analyzer built in that visualizes the data. Go to Settings → Memory to see a detailed file distribution diagram.

The system automatically sorts content into categories: apps, images, videos, documents, etc. Often it turns out that the lion's share of space is occupied by messenger cache or forgotten downloads from the browser, visual analysis helps quickly identify the "eaters" of space.

Note the "Other" section, which often includes system update files that are not automatically deleted, or remnants of deleted programs, and if this partition is larger than 10-15 GB, manual verification through the file manager is required.

Use of the built-in "Security" application

The easiest and safest way to free up space is to use the regular Security app, which is preinstalled on all Xiaomi smartphones. It contains a special “Cleanup” module that scans the system for temporary files, residual debris and large unused files.

Launch the app and press the Clean button, and the system will prompt you to delete the cache, the ad files, and the residues of the deleted applications, a basic procedure that you should do regularly, at least once a week, and MIUI algorithms are smart enough not to affect important system data.

Cleaning the cache of messengers and social networks

Messengers like Telegram, WhatsApp and Viber are the main sources of garbage on any Android smartphone, storing every photo, video and voice message viewed in memory of the device, and over time folders with media files can grow to tens of gigabytes.

In Telegram, cleaning is done most efficiently through the settings of the app itself. Go to Settings → Data and memory → Memory Use. There you will see a slider "Storage media" - set the value of "3 days" or "1 week." Also click "Clean cache" to remove the accumulated garbage.

For WhatsApp, the situation is similar, but the files are stored in a shared folder of the system. Better use the built-in storage management function: Settings → Data and Storage → Storage Management. Here you can sort the chats by size and remove heavy attachments selectively.

Remember that once you clear the cache in the messengers, when you re-open old photos or videos, they will be downloaded from the Internet. Make sure you have access to Wi-Fi or mobile traffic if you decide to view your correspondence history.

Removal of duplicates and large files

Often, the phone has files that the user doesn't even know exist, such as duplicate photos taken when the camera crashes or forgotten movies downloaded a few months ago, and Xiaomi's standard Explorer is the best way to find them.

Open the Files app and go to the Categories or Recent tab. Pay attention to the Big Files section. The system will sort the content by size, and you'll immediately see videos that weigh 2-3 GB that can be ruthlessly deleted or moved to your computer.

Work with Gallery and Cloud Services

Photos and videos are the most space in a smartphone today. If you like high-resolution photography, memory runs out very quickly. The best solution is to use cloud services like Google Photos or Xiaomi Cloud.

Set up automatic sync with the cloud. Once you upload your photos to the server, use the "O Free Space" feature (in Google Photos) or similar in the MIUI Gallery, which will remove the originals from your phone, leaving them available for viewing over the Internet.

Remember to check the "Basket" album in the gallery. Deleted photos don't disappear forever, but they're stored there for 30 days, continuing to occupy space. If you accidentally delete an important photo, it can be restored, but if you need a place urgently, the basket needs to be cleaned manually.

⚠️ Before mass cleaning of the gallery, make sure that the sync is successful. Check the availability of the photo through the web interest of the cloud service from the computer, so as not to lose important moments forever.

Special features and hidden folders

MIUI has a Hidden Album or Second Space feature that can hide large amounts of data, and if you've used these features, check the contents, and files in Second Space are in your main memory, but you can't see them in normal viewing.

It's also worth a look at the folder. MIUI It's often the voice recorder, the call records, and the screenshots of the errors. sound_recorder It may contain old recordings of lectures or meetings that have already lost their relevance.

For advanced users, cleaning through developer mode or ADB is available, but this requires caution. The average user needs to know about the existence of an Android/data folder where applications store their caches. Direct deletion of files from there can reset application settings.

💡

Regularly checking hidden folders and second space allows you to find hidden memory reserves that are not displayed in standard storage analysis.
