How to effectively clean the memory on Xiaomi Redmi 4

Redmi 4 series smartphones, including Prime and Standard, are still popular due to their reliability, but their built-in storage is often limited to 16 or 32 gigabytes. Over time, the system becomes overgrown with temporary files, messengers accumulate gigabytes of media files, and the user simply stops noticing how free space is approaching zero, which leads to slowdown of the interface, app freezes and the inability to install new updates.

Cleaning up memory on a MIUI device requires a comprehensive approach, because simply removing applications is not enough. You need to work competently with cache, system logs and heavy media folders, which are often hidden from the eyes of the average user. In this article, we will discuss proven optimization methods that will help return your gadget to its previous speed without losing important data.

Before we start taking any drastic measures, we need to look at the current state of the storage and understand what exactly takes up the most space, and it often turns out that half of the volume is occupied by old WhatsApp videos or forgotten screenshots, the removal of which will not cause any harm to the system. Let's take all the steps of cleaning in order.

Analysis of vault occupancy

The first step should always be diagnostics. Xiaomi owners have a built-in analysis tool, but it doesn't always show the full picture. A standard analyzer is good for quick verification, but it's better to use third-party utilities or built-in explorer with analysis function to get a deeper understanding of file structure.

The most frequently clogged sections are those related to media and social media cache. Android stores copies of images and videos viewed to upload them faster when reopened, but over time, this data turns into digital garbage, and offline navigator maps and downloaded music playlists can also take up a significant amount.

⚠️ Warning: Before deleting any files from system folders, make sure they don't contain important settings or game saves.Delete system logs is safe, but touch prefixed folders Android/data need to be careful.

For accurate definition of heavyweights, you can use the built-in functionality or download a specialized application. Below is a table showing the typical distribution of space on a filled phone:

Use of the built-in "Security" application

MIUI is famous for its aggressive approach to memory cleanup, and the built-in Security app is the first tool worth using. It can find residual files, duplicates and cache that has been left unused for more than 30 days.

However, it is important to understand that a standard scanner does not always find all hidden files, it works according to known algorithms and can skip large files in non-standard directories, but regular use of this tool helps maintain system hygiene and prevents the accumulation of small debris, which in total gives a tangible result.

It's important not to rely solely on automatic mode. In the "Cleanup" section, you can often find the "Big Files" category, where you can find old.apk installation packages or downloaded movies that you might have forgotten about.

💡

Set up an automatic cleanup in the Security app so that your phone deletes temporary files every 3 days to prevent critical memory overflow.

Manual cleaning of cache and application data

The most effective way to free up space is to manually manage specific application data. Social networks and instant messengers like Telegram, Viber and WhatsApp have a habit of storing all the media files viewed in the device's memory. Even if you delete correspondence, files can remain in the app's cache.

To clean up, you have to go to your phone's settings, select "Applications" and find what you want. There are two important buttons inside the app menu: "Clear cache" and "Clear data." One deletes temporary files, the other resets the app to a state immediately after installation, requiring reauthorization.

• 📱 Open the Settings. → Annexes → All applications.
• 🗑️ Find the “heaviest” application (usually a browser or social network).
• ⚡ Click Clear Cache – it is safe and will not delete your logins.
• 🔄 For instant messengers, use the built-in cleaning inside the application itself.

And you should pay special attention to Chrome or MIUI Browser, which cache pages for fast loading, and in a year of use, this cache can grow to incredible sizes. Regular cleaning of the history and cache of the browser is a mandatory procedure for owners of devices with low memory.

Working with messaging junk

Messengers are the main memory eaters on Redmi smartphones. The problem is that standard cleaning through Android settings often doesn't affect nested media folders inside messenger directories. For example, WhatsApp creates backups locally that can take several gigabytes.

Inside WhatsApp itself, there's a great storage management feature that lets you see which chats are taking up the most space, and you can selectively delete media files, for example, you can leave text messages, but delete all videos and GIFs from group chats, which immediately frees up a lot of volume.

For Telegram, the situation is simpler: this messenger stores the cache in the cloud, and it can be painlessly cleared at any time without losing correspondence. Just go to Settings → Data and memory → Memory Use and set autodelete the cache, for example, in 3 days or a week.

⚠️ Note: When cleaning messenger data, make sure you have a backup of important correspondence in the cloud, otherwise you may lose your message history without the ability to restore it.

Remember to check the Documents folder in messengers, and often heavy presentations get there, PDF-files and archives that were sent six months ago and are no longer needed, and deleting them is the fastest way to get free space right now.

Removing duplicates and hidden files

When you use your smartphone, especially when you send files frequently or edit photos, you accumulate duplicates in memory. The MIUI shell in recent versions has a built-in tool for finding copies, but if you have an older version of the software, you will have to use a file manager.

Hidden files are often created after deleting applications. Residual folders with the names of remote programs can lie at the root of internal memory or in a folder. Android/obb. Finding them requires care, but removing such "orphans" is safe for the system.

It's also worth checking the DCIM/.thumbnails folder, which is a hidden system folder that stores thumbnails of your photos for the gallery. Sometimes the.thumbnails file grows to the size of the original gallery, taking up gigabytes. It can be deleted, the system will create a new, smaller size.

Transfer data to memory card and cloud

If internal memory is crowded, the logical solution is to use an external microSD card. Redmi 4 supports cards up to 128 GB, which allows you to transfer all photos, videos and music, freeing up precious internal space for the system to work.

The modern approach also involves using cloud storage, services like Google Photos or Yandex.Disk can automatically upload your images to the cloud and delete them from the device, leaving only previews, which creates the illusion that all photos are in place, but physically they take up space on the Internet.

There are limitations to porting apps to a memory card in Android, and not all programs support this feature, and even when you transfer some of the data, it still remains in internal memory, but for heavy games and media applications, this can be a lifesaver.

• ☁️ Set up sync photos with Google Photos in the mode "Saving space".
• 💾 Format your memory card as internal storage (if the Android version allows).
• 📂 Manually move the folders Download and DCIM on SD-conductor.

Moving system applications or active games there can lead to lower performance and increased level load times.

💡

Using cloud storage with the “free up space” function is the best way to have access to all photos of the phone’s internal memory devoid.

Radical Methods: Resetting and Root Rights

When software methods don't work, the last thing you can do is reset the entire factory settings, and it deletes absolutely all the data, and it puts the phone back in a store-like state. Make sure you back up your contacts and your important files before you do that.

For advanced users, there is a option to obtain Root rights, which gives full access to the system, allowing you to remove pre-installed Chinese applications (bloatware), which take up space and are not deleted in the usual way, but this deprives you of warranty and can disrupt the operation of banking applications.

There are special scripts and modules for cleaning the system partition /system, but using them on Redmi 4 requires caution. Incorrect deletion of the system file can lead to a "bottle" (infinite reboot).

⚠️ Attention: Getting Root Rights and Unlocking a bootloader on Xiaomi Requires Waiting 7-15 Days and Mi Account. Do this only if you fully understand the risks.

If you decide to reset, use the "Extended Reset" feature in the Recovery Recovery menu to ensure that you erase all traces of previous use and file system error.
