How to Clean Memory Xiaomi Redmi Note 5: From Basic Methods to Deep Cleaning

The Redmi Note 5, released in 2018, is still a popular device due to its balance between price and performance, but over time, the built-in storage inevitably fills up. Users often face a situation where the system issues a notification of a shortage of space, which leads to a slowdown in the interface, the inability to install app updates or even refusal to make calls. Understanding how to effectively manage the file system becomes a critical skill for extending the life of the gadget.

In this article, we will not only look at standard methods for removing redundant files, but also delve into the hidden parts of the MIUI system that allow you to free up gigabytes of space, quietly occupied by garbage. You will learn which folders can be deleted without risk to the system, how to analyze the volume of data of specific applications and why overflowing internal memory affects the speed of writing new data.

Before embarking on radical measures like factory resets, it's worth trying less aggressive methods that often solve 90% of space shortage problems.Modern instant messengers and social media tend to accumulate huge amounts of cached data that the user may not even know about.We'll look at tools built into Xiaomi's shell, as well as third-party utilities that will help visualize the structure of your storage.

Storage occupancy analysis and system tools

The first step in the battle for space should be diagnostics. Redmi Note 5 owners often delete files at random, not realizing what is the bulk of the file. The built-in Security app provides a basic but useful tool for analysis. When you start Cleanup, the system scans the device for temporary files, residual debris after deleting applications and large unused files.

But the standard scanner doesn't always show the full picture. For a more detailed look, you need to go to the storage settings. Here you'll see a breakdown by category: apps, images, video, audio, etc. It's important to look at the "Other" section, which is often inflated to tens of gigabytes due to the cache of messengers and offline maps of navigators.

⚠️ Warning: Don't try to manually delete files from system folders through a file manager unless you're 100% sure of their purpose.Deleting critical libraries can lead to a cyclical smartphone reboot.

For deep analysis, we recommend using disk space visualizers, which build a memory card where each block is the size of a file, which allows you to instantly find forgotten video files or error logs that occupy space, and the standard MIUI Explorer also has a file sorting function by size, which helps you quickly identify heavyweights.

Cleaning the cache of applications and garbage messengers

The most voracious apps in the Android ecosystem are traditionally messengers like Telegram, WhatsApp and social networks, which store every image, video and voice message viewed into local memory. Over time, this cache can reach 10-15 GB, which for the Redmi Note 5 with its modest base memory is a disastrous figure.

Unlike simply removing an application, clearing the cache through the system settings allows you to save your login and correspondence data by only deleting temporary files. To do this, go to Settings → Apps → All Apps, select the desired application and click Memory. There are two buttons available: Clear cache and Clear all. The second button will completely reset the application as if you had just installed it.

Special attention should be paid to the settings inside the messengers themselves. Telegram, for example, has an automatic cache clearing feature that many people ignore. WhatsApp can set up the option of not downloading media files to the phone gallery, leaving them only available inside the chat room, which saves space in the shared gallery.

It’s also worth checking out video viewing apps and streaming services. YouTube, Netflix and various online cinemas often save offline content that gets forgotten and continues to take up space for months. Regularly checking downloads in these apps is a good habit to maintain order.

Working with DCIM folder and duplicate photos

Media content is the one that takes up the most space on any modern smartphone. The DCIM folder contains all your photos and videos taken on camera. Over time, it accumulates unfortunate footage, screenshots, long videos in high resolution and panoramas. The Redmi Note 5 has a camera that takes high-quality pictures, but videos in 4K or FullHD quickly eat up the free space.

The MIUI shell has a built-in Gallery tool that automatically finds similar images and suggests you pick the best ones by removing the rest. It's a convenient way to quickly get rid of serial photography when you're trying to capture a moving object. Also worth paying attention to the Screenshots album, which often contains images that were relevant a week ago but are no longer needed.

Cloud storage is the most efficient way to offload memory without losing data. Services like Google Photos or Yandex.Disk can automatically upload original photos to the cloud and delete them from the device, leaving only thumbnails, which creates the illusion that all photos are in the gallery, but physically they take up space on the server, not on the flash memory of the smartphone.

Removal of system debris and residual files

When Android apps are removed, there are often empty folders or configuration files that are no longer in use but continue to be dead weight. These so-called “residual files” may not take up gigabytes, but their accumulation leads to fragmentation of the file system and slowing down data search. Periodic revision of the root directory helps maintain order.

In the Redmi Note 5 file system, you should pay attention to the Download folder. Browsers and applications often save installations there. APK-file, PDF-And many people forget this partition, and they keep installers there years after they've been installed, and checking this folder is one of the quickest ways to make room.

There's also a folder. MIUI/debug_log, If you're not a developer and you're not debugging the system, you don't need these logs. They can range from a few megabytes to hundreds if the system has crashed and logging is running all the time.

⚠️ Note: Before removing files from root folders with unclear names, make sure to search the Internet for what this process is responsible. Deleting files with extensions.xml or.db from system folders can disrupt the application.

You can use the built-in Cleanup feature in the Security app to automate the process, but for a deeper approach, there are specialized utilities that can find broken links, empty folders and files that have not been accessed for more than six months, but even with such tools, the critical thinking of the user should remain the main filter.

Use of memory card and application portability

Redmi Note 5 features a microSD card slot, which is a lifeline for models with 32 GB of internal memory. Using an external card correctly allows you to transfer the bulk of media content, leaving internal memory free for the system and the cache of active applications. This greatly increases the responsiveness of the interface.

In modern versions of MIUI and Android, the ability to fully port applications to the memory card (Adoptable Storage) is often limited or absent by default. However, you can transfer photos, videos, music and documents to the map. To do this, select a memory card in the storage settings and specify it as “Portable storage”, and then move the contents of internal memory in the file menu.

Some applications, like cameras, voice recorders and navigators, allow you to choose the default way to save data in your internal settings. Change this path to a microSD card. This will prevent the internal memory from being filled with new files in the future. The camera will immediately write video to the map without taking up precious system space.

💡

Use UHS-I or higher memory cards. Slow cards can cause delays when shooting videos or opening heavy files, creating the illusion of the brakes of the smartphone itself.

The read and write speeds of a microSD are usually lower than those of the built-in eMMC 5.1 module in Redmi Note 5. Therefore, it is not recommended to install heavy games or applications that require fast data loading on a map, this can lead to unstable operation.

Radical measures: Resetting to factory settings

If neither cache cleaning, file deletion, or memory card helps, and the smartphone continues to signal a lack of space, the final argument is a full reset, which returns the device to the “out of the box” state, removing absolutely all data, settings and applications, which is guaranteed to free up 100% of user memory.

Before doing this, it is critical to back up. MIUI has a built-in Local Backup tool that allows you to save contacts, messages, call logs and system settings to a file. This file can then be transferred to a computer or memory card. Photos and documents must also be copied to an external medium.

The reset process is triggered via the Settings menu → Advanced Settings → Restore and Reset → Reset. The system will alert you that all data will be destroyed. Once confirmed, the smartphone will restart and begin the cleanup process, which can take from 5 to 15 minutes. Once turned on, you will get a clean system with maximum free memory.

⚠️ Warning: Make sure the battery is at least 50-60% Interrupting the recovery process due to battery discharge may cause damage to the system partition and inability to boot.

After you reset, take your time to install all the apps at once. Try using a clean phone for a couple of days. Often it turns out that half of the programs you previously installed don't really need you. Install the apps selectively, monitoring their impact on memory from the first days of use.

💡

Complete resetting is not just about cleaning up a place, it’s about re-building digital hygiene and preventing the accumulation of garbage in the future.

Overcrowding prevention and digital hygiene

To keep the memory problem on the Redmi Note 5 from returning in a month, you need to develop digital hygiene habits. Regularity is a key factor. Set aside 10-15 minutes once a week to check uploaded files and clean up the cache of heavy applications, which takes less time than the subsequent treatment of a bloated system.

Turn off autoloading media files in instant messengers, unless absolutely necessary. Let the pictures load only by click. This will not only save space, but also reduce traffic consumption. It is also worth unsubscribing to channels and chats that generate a huge stream of useless content deposited in the memory of the phone.

Use cloud-based alternatives to local storage: Google Docs, music streaming services, movies online, all of which allow you to share content without taking up a single byte on your device. In the era of high-speed mobile Internet, storing terabytes of data in your pocket is becoming less relevant.

Xiaomi engineers periodically release optimizations for file systems and memory algorithms in MIUI updates. While newer versions may be heavier than older ones, they often contain memory leak fixes and improve cleaning mechanisms.
