How to Clean Xiaomi Redmi: The Complete Acceleration Guide

Many users notice that over time, their once-fast Xiaomi Redmi starts to run slower, apps open longer, and the interface reacts with a noticeable delay, most often due to overcrowded internal memory and accumulated system debris. Smartphone owners often wonder how to clean up the Xiaomi Redmi to return it to factory speed without losing personal data.

Effective cleaning of the device requires a comprehensive approach. It is not enough to simply delete a few photos, you need to deal with the cache of applications, residual files and background processes. Proper maintenance of the gadget prolongs its life and ensures the stability of the MIUI operating system. In this article, we will discuss in detail all available cleaning methods.

There are many ways to optimize, from built-in memory cleaning tools to radical resetting. We'll look at safe methods that are suitable for both power users and beginners. It's important to act consistently so that you don't delete important system files that are necessary for the phone to work properly.

Use of the built-in "Security" application

The first and most affordable tool for maintenance is the standard app, pre-installed on all Xiaomi devices, called Security, and it has a shield icon, which is designed specifically for the MIUI shell and allows you to quickly free up space.

To get started, launch the app and click on the big Cleanup button, and the system automatically analyzes the storage and finds temporary files, remnants of deleted programs and advertising debris, the process takes only a few seconds, after which you will see a list of the garbage found.

But automatic analysis doesn't always find anything else, so you can manually select categories from the cleaner menu for deeper inspection, for example, check the Big Files section, which often hides forgotten videos or archives that take up gigabytes of space.

Don't just rely on automatic cleaning. Check the Deep Clean section inside the app regularly, and you can find duplicate photos and unused APK installation packages that often remain after software updates.

Manual cleaning of cache and application data

Social networks and instant messengers typically occupy the largest amount of memory, with apps like Telegram, WhatsApp, and TikTok storing vast amounts of temporary files to quickly load content, and over time, this cache can grow to tens of gigabytes, significantly slowing down Redmi’s work.

To clean a particular application, go to Settings → Apps → All Apps. Select the program you want from the list and click on Memory. Here you will see two buttons: Clear cache and Clear everything.

⚠️ Caution: Clicking the Clear Everything button will not only delete temporary files, but also your logins, passwords and correspondence within this application.

It is recommended to clean the cache regularly, not the data. This is safe and does not require re-authorization. For some applications, such as YouTube or browsers, the cache volume can be very large, and its removal will significantly speed up the device.

Galleries and cloud services deserve special attention. If you are syncing with Google Photos or Xiaomi Cloud, check if the original photos are stored in the phone’s memory after uploading to the cloud.

Storage analysis and removal of hidden debris

Sometimes standard tools don't show what's taking up space, and in these cases, the built-in storage analyzer helps, it visualizes the data and shows which folders weigh the most, and it allows you to find hidden files that aren't displayed in a normal file manager.

To access this tool, go to Settings → About Phone → Memory. Click on Clear or Analyze. The system will build a data distribution diagram. Often, folders from games or photo editing programs that have been deleted for a long time are taking up a lot of space.

It's also worth checking the Android/data folder, which stores game and heavy-duty apps data, and if you delete a game but the folder with its name (e.g. com.pubg.imobile) is still there, you can delete it manually through the file manager.

Cleaning through Developer Mode and ADB

For advanced users, there is a way to clean up through USB debugging, which removes system debris that is not available by conventional means, but requires a connection to a computer and the installation of ADB drivers.

First, activate the developer mode, and then quickly tap the MIUI version number seven times in the About Phone menu, then turn on the USB debugging menu that appears.

Connecting your phone to your PC can be used to clear Dalwick's cache and other system partitions, which is especially useful if the device is unstable after the system update. Adb shell pm trim-caches 999999999 allows you to force the cache of all applications at once.

adb shell pm trim-caches 999999999

Excessive cleaning of system caches can cause applications to load longer on the first run after the procedure, as they will have to recreate the necessary temporary files.

Removal of viruses and advertising software

Often, malware is not the cause of slow work, but rather the system files. Advertising viruses can mine cryptocurrency in the background or show banners on the desktop. If your Xiaomi Redmi is behaving strangely, you need to check for viruses.

The built-in antivirus in the Security app uses databases from Avast and AVL. Run a scan to find threats. If the built-in scanner finds nothing but suspicions remain, install a third-party antivirus, such as Malwarebytes or Kaspersky.

• 🦠 Check the list of installed applications for programs with strange names or without icons.
• 🚫 Revoke administrator rights from suspicious programs in the security menu.
• 🔍 View the list of apps with access to “Above Other Windows” – viruses often hide there.

Pay special attention to applications that you downloaded from outside the official Google Play store. Third-party sources often contain modified versions of programs with embedded advertising code.

Radical measures: Resetting to factory settings

If no methods help and the phone continues to slow down, the last resort is a complete reset, which will return the Xiaomi Redmi to the state it was in at the time of purchase.

Before starting the procedure, make sure that the battery is more than 50%. Go to Settings → About Phone → Reset. Select “Erase all data” and the system will warn you that you can not restore files.

⚠️ Note: After resetting, you will lose all contacts, photos and messages if you
