How to Clean Up the Internal Memory of Xiaomi Redmi 5 Phone

Despite their age, the Redmi 5 series is still popular due to its reliability and availability. However, one of the main problems that owners of these devices face in the process of operation is the rapid filling of internal storage. The MIUI system, which is the basis of the shell, requires free space for proper functioning, updating applications and temporary files.

When free memory is critically reduced, the phone starts to run noticeably slower, applications can close on their own, and new programs can no longer be installed. Lack of space also affects the stability of the camera and the ability to record high-resolution video. In this article, we will discuss in detail all methods of freeing up space, from regular system tools to advanced techniques.

Understanding the structure of the Android file system will help you not only remove excess memory, but also prevent re-filling in the future. We will look at safe ways to remove system debris, clean the social network cache and transfer media files to an external medium. Freeing up less than 500 MB of space may not give a visible increase in performance, the target is at least 2-3 GB.

Analysis of vault occupancy

Before you start deleting files, you need to determine exactly what exactly occupies space in your Xiaomi Redmi 5. Standard system tools allow you to get detailed statistics of disk space usage, which will help to avoid a situation where the user deletes important documents while gigabytes occupy the cache of messengers.

For more information, go to the Settings menu, then select Storage or Memory (the name may vary depending on the version of MIUI), and here you will see a color diagram showing apps, images, videos, audio files, etc. Storage analytics is the first step to optimize your device properly.

Note the Other section, which is often where the remnants of deleted programs, error logs, and temporary update files are hidden. If this partition takes up a disproportionate amount of space, a deeper cleanup through your computer or specialized utilities may be required. Don't ignore the large files that the system flags as unused for a long time.

Modern apps, especially social networks, tend to accumulate huge amounts of temporary data. Telegram or WhatsApp can stealthily “eat” several gigabytes, saving all media files you viewed in cache. Regular monitoring allows you to control the appetites of such programs and limit their ability to autoload content in time.

Use of the built-in “Cleanup” application

The MIUI shell preinstalled a powerful system tool to maintain the device, called Clearer, which automatically scans the device for temporary files, remnants of deleted applications and advertising debris, and running this utility is the easiest and safest way to quickly free up several hundred megabytes.

To use the feature, find the broom icon on your desktop or run the Security app and select the Cleanup tab. Click the Scan button, wait for the process to be completed and confirm the removal of the proposed files. The system will determine what can be deleted without harming the phone. Safe deletion is guaranteed by the developer's algorithms.

In addition to basic cleaning, the app menu includes additional tools such as Deep Clean, which analyzes large files, rarely used apps and duplicate photos. Be careful when using deep cleaning: always check the file list before final deletion so you don’t lose important documents.

⚠️ Attention: The "Accelerate" function in the Security app closes the background processes, but does not delete files from memory (RAM) and cleaning up the permanent storage facility (ROM).

Regular use of the built-in cleaner helps keep the system in good shape, but it is worth noting that this application removes mostly surface debris. To combat deep-seated files and the cache of heavy applications, more radical measures will be required, which will be discussed below.

Cleaning the cache and application data

The most active memory consumers in Xiaomi Redmi 5 are usually social networks and instant messengers. Viber, WhatsApp, Instagram and Telegram store every image and video viewed in a local cache. Over time, these temporary files can reach 5-10 GB, which is a significant part of the internal memory of a budget device.

To clean up, go to Settings → Apps → All apps. Find the program you want (like YouTube) and click on it. Select Memory or Storage. Here you will see two buttons: Clear Cache and Clear Everything (or Reset) and use the Clear Cache button safely and do not require re-authorization.

If you choose Clear Everything or Reset, the app will return to a state immediately after installation: you will log out and all local settings will be reset. This is an effective way to deal with bugs in the program, but it takes time to reconfigure. Always use this method only as a last resort when simple cache cleaning does not help.

Special attention should be paid to cleaning inside the applications themselves. Telegram settings have a section called Data and Memory → Memory Use, where you can set up automatic cache cleanup (for example, delete files older than 3 days). WhatsApp has a similar feature in Settings → Data and Storage → Storage Management. This allows you to delete large files selectively without touching important correspondence.

Removal of duplicates and large files

Over the years, many duplicate photos, screenshots and uploaded files accumulate in memory. Often users take multiple pictures of the same object, forget to delete failed frames or download the same documents several times, and finding and deleting such files is a great way to quickly get free space.

Use a file manager, such as built-in Explorer or third-party Total Commander. Sort files by size to find the largest. Often forgotten videos at 1080p or 4K resolution can take up 200-500 MB each. Deleting even five of these videos will free up a significant amount of space.

It is also worth checking the Download folder. This is where browsers and messengers by default save all downloaded files: PDF-documents, installations APK-And there are often installers who have been installed for a long time, and they don't need to be there.

Remember to check the Recycle Bin folder in the gallery. On modern versions of MIUI, deleted photos don't disappear immediately, but are stored for 30 days in case you're sure that the photos are no longer needed, go to the Recycle Bin album and clean it completely so that the files are physically deleted from the drive.

Transfer data to memory card and cloud

The Xiaomi Redmi 5 has limited internal memory and software-based memory, but it supports microSD card installation, which is the perfect solution for storing media files like photos, videos, music and documents, and by transferring that data, you'll free up precious gigabytes of storage for the system and applications.

To transfer files, insert the memory card into the slot (usually combined with the second one). SIM-Then, through the Explorer, select the desired folders (for example, DCIM, Pictures, Music) and select Move or Copy. Specify the path to the memory card (/storage/sdcard1 After transferring, delete the originals from the internal memory.

In addition to a physical map, use cloud storage. Services like Google Photos, Yandex.Disk or Cloud Mail.ru allow you to automatically upload photos to the Internet and free up space on your device with a single button. Google Photos has a "Free Space" feature that removes from your phone those pictures that have already been successfully uploaded to the cloud.

⚠️ Note: When transferring application data folders (such as game cache) to a memory card through the developer settings (“Remember as internal memory”), retrieval of the card may cause these applications to fail.

Cloud technology also keeps data safe: If your phone gets lost or broken, your photos will remain safe; set up automatic uploads only via Wi-Fi to avoid wasting mobile traffic; this is especially true for those who have limited gigabytes of data.

Removing Unused Applications and Games

Apps are not just the installation files themselves, they're also the data. The game can weigh 100MB when installed, but after downloading additional resources, take up 2GB. If you haven't played the game in the last six months, there's no point in keeping it on your phone, taking up space and using up battery power in the background.

Go through the installed list. MIUI has a convenient sorting system: you can sort the list by frequency of use or size from the Apps menu. Delete anything you don't use. Pay special attention to games, they are the main eaters of space. Uninstalling these programs often gives the most noticeable result.

Also, you should get rid of the pre-installed ballast. Many operators and manufacturers install unnecessary applications that can not be removed in the usual way. Removal of them may require superuser rights (Root) or using a computer with an adb command. However, for most users, it is enough to disable such applications in the settings so that they do not update or hang in memory.

Radical methods: Reset to factory settings

If none of the above methods worked, and the phone still signals a lack of space, the last but most effective option is a full reset, which returns the device to a “shop-like” state, completely removing all user data, settings and applications.

Before starting the procedure, it is critical to back up all important data. SIM-If you're on a map or Google account, transfer your photos and documents to your computer or to the cloud, you can't recover deleted files without a backup. Make sure you're at least 50 times battery powered%.

To perform the reset, go to Settings → Advanced Settings → Restore and Reset. Select Settings Reset and confirm the action. The phone will restart and the cleanup process will take a few minutes. Once turned on, you will get a clean system with maximum free memory.

⚠️ Warning: Full reset deletes ALL data, including photos, contacts and messages. Make sure you have an up-to-date backup before clicking the Reset button».

After reset, don't rush to install all the applications back at once. Set only the minimum you need. This will help keep the system clean and fast for a longer time. Repeat the cache cleaning routine and delete unnecessary files regularly so that the memory overflow problem does not arise again.
