How to Clean Up Internal Memory on Android Xiaomi Redmi

When Xiaomi Redmi starts warning about a shortage of space, it is a signal to take immediate action.A filled drive not only limits the installation of new applications, but also significantly slows down the entire MIUI operating system.The processor is forced to spend resources on finding free blocks to write temporary data, which causes interface lags and brakes in games.

Cleaning up internal memory is not just about removing unnecessary photos, but about working with system debris, app cache and hidden folders. Owners of Redmi Note smartphones and Xiaomi Poco series often face aggressive storage filling due to the nature of the shell. A competent approach will allow you to free up gigabytes without losing important data and having to buy a new gadget.

In this article, we will explore proven methods of freeing up space, from built-in tools to advanced folder analysis techniques. You will learn how to safely delete unnecessary files and prevent memory from filling up quickly in the future.

Analysis of storage occupancy through settings

The first step is always to diagnose, to understand exactly what takes up precious gigabytes on your Android device, and to provide built-in tools for visualizing data that users often ignore, even though they are the most accurate.

To start, open the Settings menu and look for About Phone or Warehouse. Depending on the version of MIUI, the path may be slightly different, but the point remains the same: the system will show a diagram of the space distribution, and you can see how many apps, images, videos and system files take.

Note the Other category, which is often a hidden reservoir of messenger data, remnants of remote programs, and system logs, and if this partition is bloated to an incredible size, you'll need to manually clean through a file manager or specialized utilities.

💡

Use the built-in storage analyzer immediately after you buy a new smartphone to create a “baseline” and understand how much space the system takes up.

Don't rush to delete files marked as system if you're not sure about their purpose.The error could lead to a cyclical Redmi reboot.It's better to focus on user-generated content and the cache of third-party apps that are safe to clean.

Use of the built-in “Cleanup” application

Each Xiaomi smartphone has a Security system app (a shield icon) preinstalled, and inside it is a powerful Cleanup tool that scans the device for temporary files, advertising debris and large files.

Run the scan and wait until the process is complete, and the system will prompt you to delete files larger than 25MB that you haven't opened in a long time, which can be old APK installation packages, forgotten videos from messengers or unnecessary documents.

It's important to distinguish between "safe trash" and important data. The MIUI app usually correctly identifies the cache, but before mass cleaning photos and videos, it's better to double-check the list manually, sometimes with screenshots with passwords or important checks.

Deep Clean, which allows you to find duplicate photos, similar images and rarely used applications, and removing duplicates is the fastest way to recover a few gigabytes of free space without losing the quality of the media archive.

Clearing the cache and data messengers

The leaders in memory consumption are traditionally Telegram, WhatsApp and Viber, which store every photo and video you see in your phone’s memory, creating huge archives. Standard cleaning through Android settings often does not affect internal databases of messengers.

The most effective way is to use the built-in tools of the apps themselves. Telegram needs to go to Settings → Data and memory → Memory use and clear cache. There you can also set up autodeletion of media files so that they do not last forever.

WhatsApp is more complicated because it stores media files in a shared folder, and it is recommended to use a file manager, go to the Android/media/com.whatsapp folder, and delete the contents of the Media folders, saving important files beforehand, and click on the contact name and select Media, Links and Documents for selective removal.

💡

The messenger cache can take up to 60% of the phone’s total free memory, so regular cleaning is mandatory for comfortable operation.

Don't forget about VK and Instagram, which cache image feeds for quick scrolling, and in the app settings, look for "Clear Cache" or reinstall the app if the cache has grown to a giant size and isn't being cleaned by the usual means.

Working with DCIM folder and gallery

Most of the user data is usually stored in the DCIM folder. This is where your photos and videos are located. High-resolution (4K or 1080p at 60 frames) videos eat up space at an alarming rate.

Album review. Often, Xiaomi Gallery creates separate albums for screenshots, camera selfies, and videos. Deleting failed frames and blurred shots is a simple but effective measure. Also check the Screenshots folder, where digital junk often accumulates.

Consider moving your archive to a cloud storage or computer. Services like Google Photos or Yandex.Disk allow you to free up space on your device with a single button, leaving a preview in the gallery, ideal for owners of models with a small amount of internal memory.

If you shoot video often, check your camera settings. It may be worth lowering the resolution or frame rate if the free space is critically low. HEVC (H.265) format allows you to save up to 50% of space while maintaining quality compared to standard H.264 if your phone supports encoding in this format.

Removing hidden files and system debris

Some files are hidden from the user’s eyes and standard analyzers, such as error logs, remnants of deleted games or temporary browser files, and require a file manager with access to hidden folders, such as MI File Manager or Total Commander.

Turn on hidden files in your Explorer settings (usually the “Show Hidden Files” box). Look for folders with names of remote games, Temp, Log, Cache folders at the root of internal memory. Be careful: deleting system files can disrupt Android.

Pay special attention to the Download folder. Browsers by default save all downloaded files there, and in a year there can be several gigabytes of forgotten installers and documents, regular cleaning of this directory is a good habit.

Uninstallation of unused applications and services

Apps not only take up space with their installation file, but they also grow as they go along. High-performance graphics games can take up 3-5GB each, and if you haven't played them for months, ruthlessly delete them.

Go to Settings → Apps → All apps. Sort the list by size. You'll be surprised to find that some rare app takes up more space than your entire music library. In the app's details, click Delete.

For Xiaomi system applications that cannot be removed in the standard way (e.g., redundant browsers, game stores, preinstalled services), you can use the disable method. Go to the app properties and click Disable. This will hide the application and stop its background processes, although space will be slightly freed up.

There are also bloated apps that take up little space when installed but have huge cache, including offline map navigators and streaming services with downloaded music, check their settings and delete downloaded content if it is no longer relevant.
