Despite its age, the Xiaomi Redmi 5A is still a popular device due to its reliability and availability. However, over time, any smartphone starts to run slower, memory becomes overflowing, and the system becomes overflowing with temporary files. Cleaning up a device is not just about removing photos, it is a comprehensive system maintenance process that will return the device to its former friction.
In this article, we’ll look at all the optimization options, from quick cache cleanup to radical reset to factory settings. You’ll learn how to safely remove system debris, free up precious space in internal memory, and prepare the gadget for sale or transfer to another user. Proper cleaning can extend battery life and speed up application launches.
Before we start taking drastic measures, we need to understand what exactly occupies space in your device. Often users do not even realize that messengers and browsers accumulate gigabytes of hidden data. We will look at MIUI tools that allow you to effectively manage storage without installing third-party software.
Memory Occupancy Analysis and Hidden Files Search
The first step before any deep cleaning should be diagnostics. owners of Redmi 5A often face a shortage of internal memory, which in the basic versions is only 16 or 32 GB. Android system and the MIUI shell occupy a significant part of this space, leaving the user a limited resource for personal needs.
To start with, you need to use the built-in analyzer. Go to Settings → Storage. Here you will see a color diagram showing the distribution of data. System files usually occupy a fixed amount, but the "Other" or "Apps" section can inflate to obscene size. Note the messenger folders: WhatsApp and Telegram are the main "eaters" of memory, saving every photo and video viewed to cache.
⚠️ Before deleting files from instant messenger folders, make sure that important documents and photos are saved in the cloud or on your computer.
It's also worth checking the Download folder, which is where all the files from the Internet are stored by default. APK-Files that are no longer needed or old presentations, and removing those files is the quickest way to make room without risking damage to the system.
💡
Use the built-in Cleanup app for quick scanning, which safely removes advertising debris and temporary files, but does not touch personal data.
Cleaning the cache of applications and system debris
Cache is a temporary file that applications create to speed up their work, such as the browser saves copies of pages, and maps saves fragments of maps of the terrain. Over time, this cache can take up hundreds of megabytes, which for the Xiaomi Redmi 5A with its modest amount of RAM is a significant brake.
There are two ways to clear the cache: one is global, through the cleaning menu; the other is selective, for heavy applications; to clear everything at once, open the Security → Cleanup app. The system will scan the device and prompt you to remove Garbage. It's safe and won't affect your logins or saves in games.
If a particular app is not working properly or takes up too much space, it is better to clean it individually. To do this, go to Settings → Apps → All Apps. Select the desired program (for example, YouTube or Instagram) and click Clear → Clear the cache.
What is the difference between cache and data?
Also, the background is not to be forgotten. MIUI has an "Acceleration" feature that closes out unused applications. Regular use of this feature helps to relieve RAM, although it does not free up storage space. For stable operation of the Redmi 5A, it is recommended to close heavy games and editors immediately after use.
Removal of duplicates and large files
Over time, duplicate photos inevitably appear in your smartphone memory, so you could take a picture, edit it, save a copy, send it to the messenger and get it back, all of which take up space. There's a built-in tool in the MIUI shell to find those files.
Files (or Explorer) often has a tab called "Analyzer" or "Cleanup." You can find the categories "Big Files" and "Dublicates." Look carefully through the list: often there are long videos that you shot long ago but forgot to delete. Deleting even one or two videos at 1080p resolution can free up a gigabyte of space.
Also worth paying attention to is the.thumbnails folder, which is a hidden system folder that stores thumbnails of your images for the gallery, sometimes as small as a few gigabytes, and you can clean it through the file manager, enabling the display of hidden files, but the system will create it again the next time you start the gallery.
| File type | Where to find | Can be removed | Risk of data loss |
|---|---|---|---|
| Cash app. | Settings → Applications | Yes, it's safe. | No. |
| Downloads (Download) | Download folder | Yeah, unless you have to. | Medium (documents) |
| Photos | DCIM, Pictures | Just extra. | High-pitched |
| APK installers | Download folder/APK | Yes, after installation. | No. |
Regularly reviewing the library is a key to free memory, and make a rule: once a month, watch the video album and delete the unsuccessful videos, which will prevent the phone from suddenly stopping taking photos due to overflow.
Removal of unused applications and services
The Xiaomi Redmi 5A has a lot of apps that you may never use, some that you can uninstall, some that you can disable, and not only does it take up space, but it also consumes battery life and RAM in the background.
Go to Settings → Apps → All apps. Go through the list. If you see a game you haven't played in six months or a service you don't use (e.g., unwanted browsers or social networks in multiple instances), feel free to delete them. For system applications that can't be removed, a Disable button is available. This will hide the application and stop its processes.
☑️ Checklist before removing applications
Special attention should be paid to bloated apps like Facebook or LinkedIn, which are standard versions that consume a lot of resources, and the light versions of these programs are faster and take up many times less space, which is critical for the Redmi 5A.
Remember to clean the shopping cart in Google Photos and in the Gallery app itself. Deleted files often stay there for 30 days, continuing to take up space. Cleaning the shopping cart is the final touch in the process of removing unnecessary content.
Using the Developer Mode to Clean
For more advanced users, there is a possibility of fine-tuning through the developer mode. Although this does not give a direct "Clear All" button, you can control processes more efficiently here. To activate the mode, you need to click 7 times on the MIUI version in the About Phone menu.
You can find a "Do Not Stay Activated" item in the Developer Menu, and if you turn it on, the system will destroy background processes as soon as you leave the application, which will radically free up RAM, but can slow down the switching between applications, since they will be re-started each time.
⚠️ Warning: Be careful in the Developer menu. Changing animation settings or process limits without understanding can make the interface twitchy or lead to unstable system operation.
Also available in this section is the "Run Services" feature, which shows how much memory is currently occupied, which is a useful diagnostic tool: if you see a service with a vague name that eats a lot of memory, you should look it up online, maybe it's a virus or a malfunction.
Using ADB (Android Debug Bridge) commands via a computer is an even more powerful but complex method, which allows you to remove even system debris that is not available to the average user, but for Redmi 5A this may be redundant if you do not conduct deep downgrade or customization of the system.
Full reset to factory settings (Hard Reset)
If the software cleaning didn't help, the phone is bugging, slowing down, or you're planning to sell it, the only way out is a complete reset. Hard Reset will return the Xiaomi Redmi 5A to the state it left the store. All your data, contacts, photos and settings will be destroyed.
Before starting the procedure, make sure to back up.You can use Mi Cloud, Google Account or third-party software on your PC. Make sure that the battery is at least 50% so that the phone does not turn off at the most inopportune time.
There are two ways to perform the reset:
- 🔘 Through Recovery: Turn off the phone. Press the Volume Up button. + Meals at the same time. In the menu that appears, select a language (English) → Wipe Data → Wipe All Data.
Once confirmed, the formatting process will begin, and it can take 5 to 15 minutes, and the phone will reboot, and you will see the screen of the initial setup, as when you first turn on a new device, guaranteed to remove all viruses, system errors and accumulated debris over the years.
💡
A complete reset is the only tool that deletes everything permanently, and after this procedure, it will be impossible to recover data without a special (backup) copy.
