How to Clean Memory on Xiaomi Redmi Note 5A: The Complete Guide

Owners of the popular budget smartphone Xiaomi Redmi Note 5A often face the problem of lack of free space after a year or two of active operation of the device. Internal memory is filled with junk files, app cache, duplicate photos and system logs, which leads to a noticeable slowdown in the interface. Android operating system in conjunction with the shell MIUI has the property of accumulating temporary data that is not deleted automatically.

Users begin to notice that applications open longer than usual, and notifications of overflowing storage appear more often, ignoring these signals can lead to inability to install updates or correct messengers, and it is important to understand that standard uninstalling programs often is not enough to deep clean the system.

In this article, we will discuss all the available ways to clean the memory on the Xiaomi Redmi Note 5a, using built-in tools and third-party utilities. You will learn how to find hidden folders, safely remove system debris and optimize the use of resources. A competent approach will extend the life of your gadget without the need to buy a new device.

Analysis of storage occupancy and search for large files

The first step before any manipulations is to diagnose: you need to know exactly what is taking up space. Owners often delete unnecessary applications, unaware that the bulk of the photos are in high resolution or uploaded video from instant messengers. MIUI provides basic tools for visualizing data, but they do not always show the full picture.

For detailed analysis, it is recommended to use an integrated conductor or third-party disk space analyzers. The file system of a smartphone is divided into logical blocks, and understanding this structure will help avoid deleting critical system files. Often it turns out that the DCIM folder has grown to several gigabytes due to serial shooting or recording the screen in 4K.

⚠️ Note: Before deleting any files from system folders (e.g, Android/data or system) make sure you do not erase game saves or set up important applications.

💡

Use the Size Sort feature in Explorer to instantly see the heaviest files, regardless of their type and location.

Special attention should be paid to the Download download folder, where browsers and messengers by default save all received documents. The accumulated over the years of use of digital junk in this directory can take up to 20% of all available memory. Regularly checking this folder is a simple but effective habit for maintaining order.

Use of the built-in "Security" application

The most affordable and secure cleaning tool is the pre-installed Security app, which is part of the MIUI ecosystem. It automatically scans the device for temporary files, residual debris after deleting programs and large unused files. Running a deep scan through this interface allows you to quickly free up several gigabytes without risking damage to the system.

Inside the application, select the Cleanup section, where the system will prompt you to delete cache, advertising files and empty folders. Xiaomi's algorithms are quite aggressive in this regard, so you can safely agree with proposals to delete temporary data. However, you should be careful when cleaning the messenger cache, if you do not want to re-download contact avatars and old media files.

Additionally, this section includes Deep Cleaning, which analyzes the contents of installed applications, and can find and delete APK installation files that have been left over from software updates, as well as map cache and streaming services. Cache clearing does not delete your personal data, such as logins or correspondence, but may require re-authorization in some applications.

Manual cleaning of cache and application data

Automated cleaners don’t always get to the depth of specific software settings, especially social networks and instant messengers. Apps like Telegram, WhatsApp, or Viber have their own media storage mechanisms that can take up enormous space. To effectively combat memory overflow, Redmi Note 5A needs to go into the settings of each application separately.

Go to Settings → Applications → All apps and select the program you want. In the menu that opens, look for the “Storage” option, which will display two values: the size of the application itself and the size of the data you are occupying. The “Clear Cache” button is secure and removes temporary files, while “Clean All” or “Reset” will return the application to state immediately after installation, removing correspondence and settings.

Regular manual checks of heavy apps should become the norm, for example, in Telegram settings you can set an automatic cache life (for example, 3 days or 1 week), after which the old files will be deleted yourself, which optimizes the smartphone’s performance in the background without your involvement.

Working with media files and cloud storage

The Redmi Note 5A captures high-quality images, but JPG and MP4 video quickly eat up space, and the solution lies in moving archives to cloud storage or external storage, which is the only sure way to keep memory free when you use the camera.

Using services like Google Photos or Yandex.Disk allows you to automatically upload images and then delete them from the internal memory of the phone. Google Photos’ “Free space” feature automatically finds copies that have already been uploaded to the cloud and deletes them from the device, leaving them available for viewing over the Internet.

Do not forget about the microSD card. If you have an additional drive installed in your device, set the camera and voice recorder to save files immediately on it. SD-maps to keep new images from taking up precious system space, and many apps can change the way you save downloaded files in your settings.

Removing System Garbage and Hidden Folders

In addition to user-generated content, the system accumulates error logs, usage reports, and residual files from remote programs, which are hidden from the eyes of the average user, but take up space. Access to them may require the use of advanced file managers, such as Total Commander or FX File Explorer, which are able to display hidden directories.

At the root of the file system, you can often find folders with names of games or programs that have been deleted long ago, which you can safely delete manually if you are sure that they are no longer needed, and it is worth checking the MIUI folder, which can remain logs of the system and error reports, which are useful only for developers when debugging, but useless for the average owner.

⚠️ Note: Do not delete.apk files from your system folders unless you know their purpose, and never touch files in the directory. /system without superuser rights (Root).

💡

Regular manual checks of Download, Bluetooth and DCIM/Screenshots folders allow you to free up to 30% of space without installing additional software.

Cardinal measures: Resetting and formatting

If the software cleaning methods fail and the memory is refilled in a couple of days, it may be that the system has accumulated critical errors or fragmentation of the file system has reached a limit, in which case the most effective solution is a complete reset to factory settings, which will return the Redmi Note 5A to a state of "out of the store" by deleting absolutely all user data.

Before starting the procedure, be sure to back up important contacts, photos and documents. Reset can be done through the settings menu in the "Advanced Settings" section → "Reset" → "Erase all data." The process will take a few minutes, after which the phone will restart with a clean operating system.

Settings → About the phone → Reset settings → Erase all data

After a reset, it is recommended not to restore all applications from the backup at once, but to install them again as needed. Often, old backups contain the same junk you just got rid of, and clean installation ensures that only the current and necessary files get into the system.

Prevention of memory overflow

To keep the problem of space scarcity from returning too quickly, it is important to develop the right smartphone usage habits: regularly check the list of installed applications and remove those that you have not used for more than a month. Many programs tend to update and increase in size, taking up more resources even in simple.

Use the “light” versions of popular apps (Lite) if available. The versions of Facebook Lite, Telegram Lite or Google Go take up significantly less space and consume less RAM, which is especially true for the Redmi Note 5A with its modest by modern standards characteristics.

⚠️ Warning: Avoid installing questionable cleaner applications from unknown sources, as they may themselves be miner viruses or adware.
