How to Clean Memory of Xiaomi Redmi Note 4

Xiaomi Redmi Note 4, despite its considerable age, is still a popular device due to a reliable metal build and a hardy battery. However, over time, owners face a lack of internal storage, which leads to slowdowns, long downloads of applications and inability to install updates. The problem of crowded memory is relevant for models with 32 GB or 64 GB of internal space, especially if the user is actively using messengers and social networks.

The MIUI operating system installed on board has its own features of accumulating temporary files and duplicates that can take up gigabytes of usable volume. In this guide, we will detail safe and effective cleaning methods that will help restore the device to its former sharpness. It is important to understand that a comprehensive approach to file system maintenance will allow you to extend the life of the gadget without the need to immediately purchase a new device.

Before you start taking drastic measures like resetting, it’s worth trying regular optimization tools that remove a significant amount of digital junk without losing important contacts or photos. Proper storage management is a skill that every Android user who wants to keep a device on track needs.

Analysis of storage occupancy and search for large files

The first step to freeing up space is to make detailed diagnostics of what memory is doing. Often users are unaware that half of the volume is occupied by old WhatsApp videos or cache of long-deleted games. The standard MIUI Explorer provides a convenient tool for visualizing data, allowing you to quickly identify heavyweights.

You have to go to Settings → Memory to see a color diagram of resource allocation, and it's the system that tells you which categories of applications consume the most space, and storage analytics helps you make an informed decision about what you can delete without regret, and what you need to move to an external medium or to the cloud.

Special attention should be paid to the download folder, which often stores APK installation files and documentation from the Internet, which, when used, becomes a useless ballast that only slows down the file system, and deleting such files is the fastest way to get several hundred megabytes of free space.

• 📂 Check the Download folder for old app installers.
• 🎬 View the gallery and remove bad duplicate photos and screenshots.
• 📱 Use the built-in analyzer to search for files larger than 100MB.
• 🗑️ Clean the cart in the gallery, as deleted photos are stored there for another 30 days.

💡

Regular monitoring of storage prevents critical memory filling that causes system failures.

Use of the built-in "Security" application

The MIUI shell preinstalled a powerful system tool called Security, which includes a cleaner function, not just an antivirus, but a comprehensive smartphone maintenance combine that can find remnants of deleted programs and temporary files, and running deep cleaning through this interface is the safest method for the average user.

When you click on the Clean up button, the system scans all the available partitions. Auto-optimization algorithms tag files that can be deleted without harming the stability of the OS. However, be careful: sometimes the system suggests clearing the cache that you plan to use again, such as navigator maps.

💡

Use the Deep Clean feature in the Security app once a week to keep your system folders in order.

The Cleanup section also includes a large file analysis feature that works even more efficiently than a standard Explorer, which groupes data by type and allows you to massively delete unnecessary content. Regular use of this tool helps maintain free memory at least 15-20% of the total, which is critical for the performance of flash memory.

• 🚀 Click the “Clean Up” button on the Home Screen of the Security app.
• 🔍 Select the “Deep Cleanup” option to find hidden debris.
• 📦 Check the list of large files before deleting them.
• ⚙️ Set up automatic cleaning in the Security app settings.

⚠️ Note: When using the Cleanup function, read file descriptions carefully. Do not delete system logs unless you plan to send an error report to developers, as they may be needed for diagnostics.

Cleaning the cache of messengers and social networks

The most voracious apps on any Android smartphone, including the Redmi Note 4, are messengers like Telegram, WhatsApp, and Viber. They store every photo, video, and voice message they see into local memory, and over time, the folders with media files of these apps can reach 5-10 gigabytes, a significant fraction of the total volume of 32 GB.

To clean up, you need to go to the settings of a particular application, find the section “Data and storage” and select the item “Memory Use” where cache management allows you to delete temporary files without affecting important correspondence. In Telegram, for example, you can set up automatic deletion of downloaded media files after a certain period, which will save space in the future.

WhatsApp is similar, but there is a nuance with backups that are often stored locally before being sent to Google Drive. Checking the WhatsApp/Databases folder can reveal old backups that are no longer needed. Deleting them frees up considerable space, and the actual copy is still stored in the cloud.

• 💬 Open the Telegram settings → Data and memory → Use of memory.
• 🧹 Click “Clear Cache” on WhatsApp via the Storage Menu.
• 📅 Set up autodelete media in Viber and other messengers.
• 📂 Manually check the folders of applications in the explorer for the presence of old videos.

Keep in mind that cache cleaning doesn't delete your private messages or contacts, it only erases temporary files. It's a safe procedure that can be done regularly. If you delete the app data completely, you'll lose your correspondence history, so be careful when choosing the type of cleanup.

Removing applications and managing Google services

Over time, a lot of apps accumulate on your smartphone that you've stopped using, each taking up space for the installation file, but also creating its own folders of data. Uninstalling unnecessary software is the first step to clean up, but some system applications can't be removed in the standard way.

Google Play also has a tendency to accumulate data. If the app store is not working properly or takes up too much space, you can try to clear its data. To do this, go to Settings → Apps → All Apps → Google Play Services → Memory and click “Clean” This will not delete your accounts, but reset the store settings to factory.

Special attention should be paid to the pre-installed Xiaomi and Google apps, which are often called “bloatware.” If you do not use Mi Video, Mi Music or Google Movies, they can be disabled. This will not remove them completely, but will stop background processes and updates, freeing up some resources of the system.

Working with SD memory card and data transfer

The Redmi Note 4 is equipped with a hybrid slot that allows you to use a microSD card. This is a great solution for storing photos, videos and music, but not all applications will agree to move to an external medium. SD-map for security and stability reasons.

To make the most of external memory, you need to configure the camera and messengers to save media files exactly there. → Save it on. SD-On WhatsApp, you can change the save path in chat settings, and that prevents internal memory from filling up quickly.

⚠️ Warning: Do not format your memory card as “internal storage” on older versions of Android unnecessarily. If your card breaks or your phone is reset, your data may be lost irretrievably and it will be difficult to restore it on another device.

Also consider the speed of the memory card. Cheap cards of class 4 or 6 can slow down the smartphone if you move some applications to them. Use cards of standard UHS-I Class 10 or higher for comfortable speed of reading and writing. If the card is slow, the system can start to work unstable.

• 📸 Reconfigure the camera to save photos and videos SD-map.
• 🎵 Transfer music and movies to external media via computer.
• 📱 Use it. SD-High speed card (Class) 10/U3).
• 🔄 Check the card for errors regularly through your phone settings.

Radical methods: Reset to factory settings

If none of the above methods worked and the phone continues to slow down, the final argument is a full reset to the factory settings (Hard Reset), which returns the Xiaomi Redmi Note 4 to the state it was in on the day of purchase, all user data, accounts and files will be permanently deleted.

Before starting the procedure, it is critical to create a complete backup of data, you can use the Mi Cloud cloud service, Google Photos for images or make a local backup to your computer, and once reset, the system will be completely clean, without accumulated over the years of debris and software conflicts.

💡

Before resetting, make sure that the battery is at least 50%, and it is better to fully charge the device to avoid interrupting the process.

To perform the reset, go to Settings → About Phone → Settings Reset → Erase All Data. The system will request a confirmation and password from the Mi Account to protect against theft. The process will take a few minutes, after which the phone will restart and the initial setup will begin.
