Owners of the popular Xiaomi Redmi 5A budget smartphone often face the unpleasant situation when internal storage is overflowing and the system starts to work slowly. A small amount of internal memory of 16 GB (of which even less is available to the user) is quickly filled with modern applications, multimedia and system logs. This leads to annoying notifications about the lack of space and the inability to install updates or new programs.
Solving the problem requires a comprehensive approach, as standard cleaning of the basket does not always give the desired result. In this article, we will discuss proven methods that will help you free up space on the Xiaomi Redmi 5A and speed up the device. You will learn about the hidden features of the MIUI shell that allow you to remove unnecessary digital debris safely for the system.
Before we go to radical measures, such as a full reset, it is worth trying to optimize the current state of the file system. Proper resource management will allow you to extend the comfortable use of your gadget even with limited hardware characteristics. We will look at the steps from simple to more complex so that you can choose the right option.
Storage occupancy analysis and search for hidden files
The first step in the battle for space is accurate diagnostics. You need to understand what takes up precious gigabytes. The MIUI shell on Redmi 5A has a built-in analyzer, but it doesn't always show the full picture. Often, the bulk of the data is occupied by messenger caches like WhatsApp or Telegram, and folders with temporary update files.
For a detailed study, use the system settings menu. Go to Settings → Memory to see the visualization of the data distribution. Here you can find that the Other section can inflate to incredible sizes, hiding the remnants of remote applications and system logs.
⚠️ Note: Do not delete files in Android system folders and MIUI manually through the file manager if you are not sure of their purpose, this can lead to incorrect interface operation or loss of settings.
Special attention should be paid to the DCIM folder, where your photos and videos are stored. Often there are duplicate images or heavy video files that can be transferred to your computer. Also check the Download folder, where browsers by default download all files from the Internet, creating huge archives of forgotten garbage.
Use of the built-in "Security" application
The easiest and safest way to start cleaning is to use Xiaomi’s standard toolkit, which is pre-installed on every device and contains a Cleanup module that scans the device for temporary files, residual debris and large unused files.
Run the scan by clicking on the broomstick icon, and the system will prompt you to remove the cache, APK installer packages, and other debris, but it’s worth remembering that this tool doesn’t always remove the cache of heavy apps like YouTube or Instagram, as it considers this data important for fast downloading content.
💡
Use the Deep Clean feature inside the Security app to find duplicate photos and rarely used apps that can be safely removed.
For a more nuanced setup, go to Cleanup and select Big Files, where Xiaomi Redmi 5A will show you videos and archives that take up a lot of space, and you can selectively remove the unnecessary by freeing up several hundred megabytes.
- 🧹 Start scans once a week to maintain order.
- 📱 Check the Unused Applications section to remove forgotten programs.
- 🗑️ Clean the gallery cart as deleted photos stay there for 30 days.
Clearing the cache and data messengers
The main memory eaters on Android devices are messengers. WhatsApp, Telegram, Viber and others accumulate gigabytes of media files that are often not needed by the user after viewing. Standard cleaning through the application settings may not give full effect, so it is better to use the built-in tools of the messengers themselves.
In Telegram, for example, you can set up automatic cache cleanup. Go to Settings → Data and memory → Memory use and set a self-delete timer for, for example, 3 days or 1 week. This will free up space on the Xiaomi Redmi 5A automatically, without your involvement.
Where is the WhatsApp cache stored on Redmi 5A?
For WhatsApp, the procedure is similar: open Settings → Data and Storage → Storage Management. Here you will see a list of chats that take up the most space, and you can delete specific videos or documents while saving correspondence. This is more effective than just cleaning the cache through Android settings.
| Annex | The path to cleanup | Recommended frequency |
|---|---|---|
| Telegram | Settings → Data and memory | Auto (1 week) |
| Settings → Storage | Once a month | |
| YouTube | Settings → General → Clear the history | If necessary, |
| Chrome | History → Clearing the data | Once a week. |
Removal of system debris and residual files
When you delete applications on Xiaomi Redmi 5A, you often have folders with their settings and temporary files, which can take up a significant amount of memory over time, and third-party file managers like Total Commander or Files by Google, which have the function of finding duplicates and empty folders, are best suited for finding them.
You should also pay attention to the folder. MIUI It's at the root of the internal memory, and it can store the error logs (debug_logs) And the themes that you've already removed from the system, and if you're not actively using the theme, you can safely delete those folders.
⚠️ Warning: Before removing any folders at the root of internal memory, back them up on your computer or in the cloud.
Another source of debris is the.thumbnails folder in the DCIM directory, which is a hidden folder where the system stores thumbnails of your photos for quick display in the gallery. It can grow to the size of the original photos. It can be cleaned, but it will be created again the next time the gallery opens.

Transfer data to memory card and cloud
Since the Xiaomi Redmi 5A supports microSD cards, this is the best way to expand storage. You can transfer all media files (photos, videos, music) to an external medium, leaving the internal memory free for application installation.
Modern cloud services also offer great solutions. Google Photos, Yandex.Disk or Cloud Mail.ru can automatically upload your pictures to the Internet and delete them from the device, freeing up space. On Redmi 5A with its modest storage capacity, this is a critical feature.
Configure sync only over Wi-Fi so you don't waste mobile traffic. Google Photos has a handy "Free Space" button that removes from your device those pictures that are already stored in the cloud, which is the fastest way to get gigabytes of free space.
- ☁️ Set up autoupload photos to the cloud for automatic cleaning.
- 💾 Use a Class 10 speed memory card to record video.
- 📂 Move the folder. DCIM to the memory card through the camera settings, if the model allows.
Radical methods: resetting and flashing
If the software methods don't help and the system keeps writing "Memory is full," it's possible that the file system is damaged or a critical amount of system debris has accumulated, in which case a full reset to factory settings (Factory Reset) helps. Before you do that, be sure to save all the important contacts and files.
To perform the reset, go to Settings → Advanced Settings → Reset and Reset → Reset. The device will delete all user data and return to the “out of the box” state. This is guaranteed to free up space, but takes time to reset.
💡
A complete reset is an extreme measure that solves problems not only with memory, but also with the speed of the system as a whole, eliminating software errors.
In some cases, especially on older versions of MIUI, it may be necessary to flash the device through the computer using the Mi Flash utility.This allows you to install the operating system completely, eliminating any software errors of data accumulation. However, a standard reset is usually enough for the Redmi 5A.
