How to effectively clean memory on Xiaomi Redmi: a step-by-step guide

Owners of Xiaomi and Redmi smartphones sooner or later face an unpleasant situation: the device starts to work slower, applications open with a delay, and the system persistently reports a lack of free space. Overflowing memory is one of the most common reasons for the decline in performance of mobile gadgets. When the amount of free data is critically small, the MIUI or HyperOS operating system can not function properly, which leads to interface failures.

In this article, we will discuss all available methods of freeing up disk space, from standard system tools to advanced file management techniques. You do not need to be a technician to clean the cache or remove unnecessary duplicate photos. Proper storage management will extend the life of your smartphone and return it to its previous speed.

So let's start by looking at what's taking up space, and we turn to practical steps to clean up the file system, and keeping a device running regularly is the key to keeping it running for years.

Analysis of vault occupancy

Before you take any drastic action to remove data, you need to understand where precious gigabytes have gone. The MIUI shell has a powerful tool for visualizing disk space. Go to Settings → About Phone → Storage to see a detailed file distribution diagram. The system automatically categorizes data by showing how much space apps, images, videos, documents and system files occupy.

It often turns out that the lion’s share of the volume is occupied by messengers like WhatsApp or Telegram, which have been accumulating media files for years, social network cache and streaming services can also have significant weight, and understanding the structure of occupancy will help you choose the right cleaning strategy without deleting important personal data.

Note the Others section: System files and data that the shell can’t classify are sometimes inflated to huge sizes due to application errors or incomplete downloads. If that partition takes up suspiciously much space, a deeper check through the file manager may be required.

⚠️ Attention: Before mass deletion of files, we strongly advise you to back up important data to the Xiaomi Cloud or to your computer. Accidental deletion of system folders can lead to incorrect operation of certain functions of the smartphone.

Storage analysis is the first and most important step in optimization, and without it, you risk removing unnecessary trifles, leaving the real space eaters in place.

Use of the built-in Security application

The easiest and safest way to clean up memory on Xiaomi Redmi is to use the regular Security app, a system tool that is deeply integrated into the shell and has the necessary access rights to work efficiently. Launch the application and select Cleanup. The system will automatically scan the device for temporary files, residual debris and cache.

Once you scan, you'll see a list of files that you can delete without risk to the system, usually advertising files, browser temporary data, and a cache of installed programs. Press the clean button to make room. Regular use of this feature helps keep the phone in good shape.

The app also includes Deep Clean, which allows you to take a closer look at the contents of your memory, where you can find large files you forgot to delete or rarely used applications, and garbage cleaning through this tool is the most recommended method for ordinary users.

• 📱 Launch the Security app on the home screen.
• 🧹 Click on the Cleanup icon for automatic scanning.
• 🗑️ Select file categories to delete and confirm the action.
• 🚀 Use the Acceleration function to close the background processes.

Don't ignore the system's cleaning notifications, which are periodically popped up, and they signal that the amount of free space has reached a critical point.

Cleaning the cache of applications and messengers

App cache deserves special attention: it is temporary data that programs save for faster content loading. Over time, the cache can grow to gigabytes, especially in the case of YouTube, TikTok, Instagram and instant messengers. Clearing the cache does not delete your personal correspondence or accounts, but returns the program to the “fresh” state.

To clear the cache of a particular application, go to Settings → Apps → All apps. Select the desired program from the list (for example, Telegram) and find Memory. There you will see the "Clear Cache" button. It is important not to confuse it with the "Clear All" button, which will reset the application to factory settings and delete your data.

For instant messengers like WhatsApp and Viber, it's better to use built-in cleanup tools. Inside the app's settings, find the Data and Storage → Storage Management section, where you can delete large video files or documents that were received in chat rooms but are of no value.

Regularly cleaning the cache of heavy applications is an effective way to free up several gigabytes of space without losing important information, especially for devices with a small amount of internal memory.

⚠️ Note: When cleaning browser data (Chrome, Mi Browser), make sure you know your passwords, as they can be deleted along with the cache if sync with your Google account is not enabled.

Work with Gallery and Cloud Services

Photos and video are the main memory consumers on a modern smartphone. Xiaomi cameras take high-quality pictures that weigh a lot. To make room, you can use the Clean feature in the Gallery app, which offers to delete blurry photos, screenshots and similar images. It is also worth checking the Recently Deleted folder, since files are stored there for 30 days and continue to occupy space.

A great solution to space scarcity is using cloud services. Google Photos or Xiaomi Cloud lets you upload original photos to the Internet, freeing up local storage. Once uploaded, you can safely delete copies from your device, which is especially convenient for archiving old photos that you rarely view.

Remember, video recordings. High-resolution (4K or 60 fps) video is a huge space, and if you don't plan on mounting those videos on your phone, it makes sense to transfer them to your computer or external hard drive, and you can also reduce the quality of video recording in your camera settings for future shootings if saving space is a priority.

💡

Turn on the “Free Space” feature in Google Photos – it will automatically delete those pictures from the device that are already saved in the cloud.

• 📸 Check the Screenshots folder and delete old screen images.
• 🎥 Sort the video by size and remove unnecessary long videos.
• ☁️ Set up automatic sync with the cloud for new photos.
• 🗑️ Don’t forget to clean the gallery cart after deleting files.

Management of the library requires periodic attention, and you can take 10 minutes a week to sort through your photos, and the problem of space shortage will bypass you.

Removal of duplicates and large files

When you use your smartphone, you inevitably accumulate duplicate files in your memory, which can be repetitive downloads, copies of documents, or identical photos taken in a series, and the standard MIUI file manager can find those files. Open the Files app and go to the Analyzer or Tools section.

The system will suggest finding duplicates and large files (usually larger than 100MB) and carefully review the list before deleting it, often containing forgotten movies, application installation files (.apk) or archives, and removing such objects can instantly free up several gigabytes.

Also worth paying attention to is the Download folder, which many users have not looked in years, unaware that there are hundreds of megabytes of advertising avenues, restaurant menus and instructions that were needed once.

⚠️ Warning: Be careful when deleting files with the.obb extension or folders with game names. their removal will lead to the need to re-download game data, which can take a lot of traffic.

Advanced methods and work with SD-card

If internal memory is severely lacking, consider expanding storage. Most Redmi models support microSD cards, you can transfer photos, music and videos to them, and set the camera to save new images immediately to the map, which will free up internal memory for the system and applications.

For advanced users, it is possible to use ADB (Android Debug Bridge) to remove system debris that is not available by conventional methods. However, this method requires a connection to a computer and knowledge of the command line. For example, cleaning the /data/local/tmp folder can help if there are accumulated debugging errors.

Another radical but effective method is factory reset, which will put the phone back into a store-like state by removing all the software debris that has accumulated over the years, and make sure to make a full backup of all the data before doing so.

• 💾 Buy a Class 10 or higher memory card to record video.
• ⚙️ Set up the photo saving by default on SD-cell-card.
• 🔄 Periodically format your computer memory card to correct errors.
• 🚫 Avoid installing applications on SD-The map, it could slow them down.

Using external memory is a great solution for media files, but do not turn the card into a system partition for heavy games.

💡

The combination of regular cache cleaning, media transfer to memory card and cloud services ensures free space on your Xiaomi Redmi.
