How to Clean Cache on Xiaomi Redmi 4

Redmi 4 series smartphones, including the Prime and X models, remain popular due to their reliability, but over time owners face a slowdown. The main cause of brakes and memory shortages is often accumulated app cache and system temporary files that take up precious space. Clearing this data is the first and safest step to speed up the device without losing personal photos or contacts.

In the Android operating system, which runs the MIUI shell, caching is necessary to quickly load frequently used functions, but the excess of files can lead to conflicts.Cache cleaning does not delete your accounts, logins or passwords, unlike a complete reset.It is a simple procedure that can be performed with the regular means of the phone without requiring a connection to the computer or installing third-party utilities.

Consider all the available ways to free up memory, from standard tools to advanced methods through the engineering menu. You will learn to distinguish between system debris and important data, which will keep the Xiaomi Redmi 4 in excellent condition for many years. Follow the instructions consistently to avoid accidental deletion of the necessary information.

Use of the built-in Security application

The easiest and recommended cleaning method is to use the standard Security app, which is preinstalled on all Xiaomi devices.This tool automatically scans the file system for temporary files, remnants of deleted programs and advertising debris.

Once the application is launched, the system will suggest you do the initial scan by clicking on the big Speed or Clean button. The analysis process takes 10 to 30 seconds depending on the amount of data accumulated. Upon completion, you will see a list of files that are safe to delete, including browser cache, image sketches and temporary update files.

⚠️ Warning: Before pressing the cleanup button, carefully review the list of files found. Sometimes the system may flag recent photos from messengers or downloaded documents that you plan to use to delete them.

For a deeper setup, you can go to Clean up inside the app and select categories manually, and you can have detailed settings for each type of data, allowing you to free up space selectively, for example, you can only clear the video cache or delete old APK installation packages, while leaving the navigation map cache intact.

Manually cleaning the cache of individual applications

If a smartphone is slow only in certain programs, such as YouTube, Viber or Instagram, it makes sense to clear the cache selectively. Accumulated data in messengers can take several gigabytes, which is critical for models with a small amount of internal memory, this method allows you to save the history of correspondence by deleting only temporary files and media cache.

To do this, go to the Settings menu and select the App. In the list that opens, find the program you want (like Google Chrome) and click on it. In the app menu, select the Memory section, where you will display the space with data and cache.

Click Clear Cache to delete temporary files. It is important not to confuse this button with Clear All or Reset, which will delete all application data, including your accounts and settings. Once the cache is cleared, the application will start a little longer than usual, as it will have to re-download the necessary resources from the network.

For instant messengers like WhatsApp or Telegram, there is an additional option to clean through the internal settings of the apps themselves, which is often a more convenient way, since it allows you to choose which media files (video, gifs, documents) to delete and which to leave.

Cleaning through the Recovery Mode menu

A more advanced method that allows you to clear the system cache (Wipe Cache Partition) without affecting the user's personal data, which is especially useful if the phone freezes when booting or after a major system update.

To enter recovery mode, you need to turn off the Redmi 4 smartphone completely. Then press the Volume Up Volume Up and Power button at the same time. Hold them until the Mi logo appears, then release the power button, continuing to hold the volume until the Recovery menu appears.

Navigation in this menu is done with volume buttons (up/down), and the choice is confirmed by the power button. Find the Wipe Data option and select the Wipe Cache option. The system will request confirmation of action - choose Yes or Confirm. After the process, select Reboot to restart the phone.

Cache removal via ADB (for advanced users)

For users who are not afraid of computer technology, there is a method of cleaning through debugging via USB and ADB (Android Debug Bridge) utility, which allows you to remove the cache of even those system applications that are limited in normal mode, which requires connecting your smartphone to your PC and having installed drivers.

First, activate Developer Mode. Go to Settings → About Phone and quickly press 7 times on MIUI Version until the message "You're a developer" appears. Then, in advanced settings, turn on the USB Debugging Toggle.

adb shell pm trim-caches 999999999

This command forcibly cuts the cache of all applications to the lowest possible value. Be careful: using the command line requires accuracy. A syntax error can lead to unpredictable system behavior. This method is especially effective at removing tails from remote applications.

⚠️ Attention: use ADB-Incorrect deletion of system files can lead to a cyclic restart of the phone (bootloop). Use this method only if you understand the essence of the actions performed.

Cleaning automation and useful tips

To avoid manual cleaning, you can set up automatic maintenance. The Security app has a Memory Acceleration feature that you can add to your desktop widgets. It is also recommended to check the Download and DCIM folder regularly, where unnecessary files often accumulate.

Use cloud storage like Google Photos or Mi Cloud to back up your media files, freeing up gigabytes of space on Redmi 4’s internal drive. Auto sync settings ensure that your photos don’t go missing even if your phone has to be completely reset.

💡

Turn off autoloading heavy applications in the settings Advanced Settings → Auto Start. This will reduce the load on RAM and reduce the amount of cache created in the background.

Remember to reboot your smartphone periodically. A simple reboot clears RAM and completes the hanging processes that can consume resources and create temporary files, just do this once every 2-3 days to maintain stable operation.
