Redmi 4A smartphones have become a legend in the budget segment, offering excellent value for money. However, even reliable devices with internal memory of 16 or 32 GB over time face a lack of free space. MIUI operating system is overgrown with temporary files, and modern applications require more resources to work.
When internal storage is overflowing, the phone is slowing down, apps can crash, and the system can freeze. Owners often notice that new photos or messages are not saved. In this article, we will discuss proven methods to help return the device to speed and free up precious gigabytes.
You will learn how to safely remove system debris, transfer data to a memory card and optimize the work of messengers. Competent approach to file management will prolong the life of your gadget and make its use comfortable.
Analysis of internal storage occupancy
Before you start taking any radical action, you need to understand what exactly occupies space. Standard Android tools allow you to study the distribution of data in detail. → Memory to see the overall picture of disk space usage.
It will show how much space apps, images, videos and system files take up. Often, it turns out that the lion's share of memory is occupied by social media cache or forgotten video files. Data visualization helps make an informed decision about what can be deleted without harming the user.
Note the Others section, which may contain remnants of deleted programs or archives of updates, and regularly monitoring this section will keep the file system in order.

Understanding the structure of busy memory is the first step to effectively clean up, avoiding the deletion of important system files.
Use of the built-in “Cleanup” application
The MIUI shell preinstalled a powerful system maintenance tool: Find the Security app on your desktop and start Cleanup. The scanner will automatically find temporary files, uninstall software residues and advertising junk.
Once scanned, the system will suggest removing the objects you find, so you can selectively deselect the files you want to save, or you can agree to the algorithm's recommendations, and that's the fastest way to free up a few hundred megabytes in one minute.
Deep cleaning is also available inside the app, allowing you to analyze large files, duplicate photos and rarely used applications, and Accelerate helps close the background processes that consume RAM.

What's an app cache?
Removal and portability of applications
The largest partition of memory is usually occupied by installed programs. Go to Settings → Applications → All applications and sort the list by size. You will be surprised to find that some games or editors take up more than 1 GB.
If you don't need the app anymore, you can remove it. For system applications that aren't required to run the phone, you can use the "Disable" function, which hides the program and stops its processes, freeing up some resources.
For applications that support external media, you can change the installation path. Go to the settings of a particular application and select Move to SD-This action will free up the internal memory by transferring the data to the external digging.
☑️ Checking applications
Remember that some apps, such as navigators or streaming services, can download content for offline access. Check their internal settings and clear up downloaded maps or playlists.
Working with messengers and social networks
WhatsApp, Telegram and Viber are the biggest memory eaters on any smartphone, and they automatically store all the photos and videos they receive into the gallery, taking up gigabytes of space, and they clean up inside the apps themselves.
On Telegram, go to Settings → Data and Memory → Memory Use. Here you can set up automatic cache clearing, for example, once a week or when space is scarce, and it is also convenient to use the Quick Clean feature, which will show the heaviest chats.
On WhatsApp, the path is a little different: Settings → Data and Storage → Storage Management. You'll see a chat list sorted by volume, and within each dialog, you can select "All Media Files" and delete them en masse.
⚠️ Before cleaning messengers, make sure that important photos and documents are saved in the cloud or on your computer, as recovery after deletion inside the application will not be possible.
Social networks like VK or Instagram also cache the feeds they've viewed, and these apps often have a "Clear Cache" option in their settings that will safely delete temporary data without leaving the acc.
💡
Set up an automatic cache cleanup in Telegram after 3 days – this will prevent the accumulation of gigabytes of garbage from the channels and groups viewed.
Cleaning the gallery and working with multimedia
High-resolution photos and videos take up the most space. Go through the DCIM and Pictures folders. Often there are screenshots, failed shots and duplicates. Deleting video at 1080p or 4K instantly frees up hundreds of megabytes.
Use cloud services like Google Photos or Yandex.Disk. They can automatically upload your photos to the cloud and delete them from the device, leaving only previews, which allows you to access all photos without taking up your phone's memory.
Remember the Recycle Bin folder in the gallery. Deleted files are often stored there for another 30 days, continuing to take up space. Clear the Recycle Bin so that the changes take effect.
| File type | Average size | Recommendation |
|---|---|---|
| Photo (JPEG) | 2-5 MB | Move it to the cloud |
| Video (HD) | 50-150 MB | Remove or compress |
| Screenshots | 0.5-2 MB | Remove after use |
| Audio (MP3) | 3-10 MB | Use streaming |
If you like listening to music, consider switching to streaming services instead of storing local libraries, which will save space for more important data.
Use of memory card (SD-map)
Xiaomi Redmi 4A features a hybrid slot that allows you to use a microSD memory card. This is the best solution for expanding storage. Buy a U1 or U3 card with a capacity from 32 to 128 GB.
Once you have the card installed, set the phone to record the default photo and video to the external media, in the camera this is done through settings, and in the file manager you can transfer the download folders.
You can also transfer some applications to the map if they support this function, which will unload the system partition and speed up the interface. SD-Map of critical system applications.
Periodically check the health of the memory card. Flash memory has a limited resource of write cycles, and over time it can fail, which will lead to data loss.
Radical methods: Reset to factory settings
If no methods help and the phone is unstable, the last option is a complete reset, which will return the device to the “out of the box” state by removing all user data, accounts and applications.
Before you start, make sure to back up your contacts and important files. Go to Settings → Advanced Settings → Restore and Reset → Reset. Confirm the action and wait for the reboot.
Once reset, the phone will work as fast as possible, install only the necessary apps so that the problem doesn't recur too quickly, and it's an effective way to rejuvenate a device that's been in use for several years.
⚠️ Warning: A full reset permanently deletes all data.Make sure you have an up-to-date copy of important documents, passwords and photos before starting the procedure.
Use this method only as a last resort, when the software cleaning is no longer working, and in most cases, regular maintenance of files is enough for a comfortable work.
