How to clean up garbage on Android shaomi redmi

Xiaomi smartphone owners and Redmi sub-brands often face a situation where the device starts to run slower and notifications of memory shortages appear at the most inopportune moment. MIUI, based on the Android kernel, has the ability to accumulate temporary files, remnants of deleted applications and error logs. These data occupy precious space in internal storage that could be used to install new programs or save photos.

Timely cleaning is not just a way to free up space, but a necessary measure to extend the life of a device. When the drive is more than 90% full, the speed of writing and reading data drops, leading to interface lags and long application runs. In this article, we will detail how to safely and efficiently remove digital debris using embedded tools and third-party utilities.

You don't have to go straight to the radical things like factory resets. There are lots of software optimizations that can help you get your phone back to speed, and we'll look at the standard MIUI shells that are already built into your phone, and we'll also look at deeper cleaning methods for advanced users.

Use of the built-in Security application

The easiest and safest way to start servicing a smartphone is to use the standard Security app, which is preinstalled on all Xiaomi and Redmi devices and has access to system partitions, allowing you to delete files that are not available to third-party cleaners. Launch the application, find a shield icon on your desktop or in the Tools folder.

Once launched, the system will automatically scan for malware and junk files.Click Clean or Clean to delete temporary files found.This process usually takes a few seconds and frees up from 100 MB to several gigabytes of space, depending on the age of the last service.

⚠️ Warning: Before pressing the full clean button, carefully review the list of files found. Sometimes the system may mark as trash important files that you recently downloaded but did not have time to move to a secure folder.

Inside the app, there are advanced tools like Cache Clearance and large file deletion. Deep Cleanup allows you to analyze the contents of download folders, APK installation packages and unused applications. Regular use of this tool is key to the stable operation of the Android operating system.

Cleaning the cache of applications and system data

The apps you use every day, such as social media, messengers, and browsers, accumulate huge amounts of cached data, such as temporary images, newsfeed videos, and web page snippets, and over time, the cache can reach tens of gigabytes, which significantly affects the available space.

To clear the cache of a particular application, go to the Settings menu, then select the App section and find All Apps. From the list, select the desired program, such as YouTube or Telegram, and click on Memory or Storage, where you will see the Clear Cache button, the use of which is safe and will not delete your personal correspondence or logins.

Special attention should be paid to the system cache, which can grow after updating the MIUI firmware. its cleaning often solves problems with the interface brakes. However, be careful: cleaning the data (not to be confused with cache) will lead to the application resetting to its original state.

• 🗑️ Browser cache – deletes visit history and temporary site files.
• 🗑️ Cash Gallery – Resets thumbnails of photos, speeding up media files.
• 🗑️ Play Market Cash – Solves Update Download Problems.
• 🗑️ Cash cards – removes offline maps and search history.

Storage analysis and removal of large files

Oftentimes, it turns out that space is not occupied by small temporary files, but by forgotten videos, duplicate photos or game installation files. The MIUI shell provides a convenient tool for visualizing occupied space. Go to Settings → About Phone → Memory to see the data distribution diagram.

The system will suggest removing files you probably don't use anymore, such as screenshots from two years ago, long WhatsApp videos, or unnecessary music tracks, and the built-in analyzer sorts files by type and size, allowing you to quickly find heavyweights.

The Download folder is worth a special attention. Browsers and instant messengers often save everything you opened there, creating chaos from documents and media files. Manually sorting this directory through the file manager Explorer can free up a significant amount of memory.

💡

Use the “Compressed Packages” feature in Explorer to find old archives that you downloaded months ago and safely forgot.

Removal of duplicates and empty folders

When you use your smartphone, you accumulate duplicate files in your memory, which can happen when you re-download the same documents or when messengers that store copies of media files in different directories fail, and having the same files not only takes up space, but also makes it difficult to find information.

You can use built-in tools or specialized applications to find copies. Newer versions of MIUI have a gallery duplicate search feature that offers to combine similar images or delete repetitive ones, and there are third-party utilities that scan the file system for identical content.

Empty folders left over from deleting games and programs usually don’t take up space, but having too many folders can slow down file indexing a little. Although modern ext4 file systems used in Android can easily handle millions of empty directories, keeping order in the root directory is a sign of good tone.

Cleaning through Developer Mode and ADB

For advanced users who want to get the most out of it, there is a USB debugging and computer cleaning method, and the command line of ADB (Android Debug Bridge) allows you to remove system debris that is not available even through root rights in some cases, which requires a connection to a PC.

First, activate Developer Mode. Go to Settings → About Phone and quickly click on MIUI seven times. Then, in the advanced settings, turn on USB Debugging. Connect the phone to your computer and use the command to clear the cache.

adb shell pm trim-caches 999999999

This command forcibly trims the cache of all applications to the lowest possible value. Be careful: using ADB commands requires accuracy, because erroneous input can lead to the removal of important system components. This method is recommended only for those who understand the structure of the Android file paths.

⚠️ Note: Never delete system files manually through root access or ADB, If you are not 100% sure of their purpose, removing critical libraries can lead to a cyclical reboot).

Prevention and optimization of the system

Once you’ve cleaned your phone of garbage, it’s important to keep it clean so the problem doesn’t come back in a month.There are simple digital hygiene rules that will help your Xiaomi Redmi run fast for years to come. Regularity is a key success factor.

Try not to install apps from unknown sources, as they often contain advertising modules that create hidden debris, and it is also recommended to periodically check the autoload list and disable those programs that you do not need immediately after turning on the phone.

• 🚀 Remove unused apps as soon as you realize they are not needed.
• 🚀 Disable auto-update applications via the mobile network, so as not to download excess.
• 🚀 Check the Recycle Bin folder in the gallery regularly, it also takes up space.
• 🚀 Use cloud storage for photos by enabling the space free function.

💡

Regular cleaning of the cache every 2-3 weeks prevents the accumulation of a critical mass of temporary files and keeps the system at a high level.
