How to Clean Memory Effectively on Xiaomi Redmi 5

Xiaomi Redmi 5, released in late 2017, is still a popular device thanks to its successful metal body and 18:9 aspect ratio screen. However, modern applications are becoming more demanding and the operating system is overgrown with temporary files, which leads to an overflow of built-in storage. Users often face a situation where the phone starts to work slowly, and notifications of space shortage appear with frightening regularity.

Cleaning up memory on this device is not just removing unnecessary photos, but a comprehensive maintenance process for the MIUI system. Internal memory with a capacity of 16 or 32 GB fills up very quickly, especially if you are actively using messengers and social networks. Proper file management will prolong the life of the gadget and avoid the need to buy a new device right now.

In this guide, we will look at all the optimization options available, from standard tools to advanced system folders, learn how to safely remove digital debris, transfer data to a memory card and control the appetites of installed programs. Regular maintenance of a gadget is the key to its stable operation for many years.

Analysis of storage occupancy and search for large files

Before you start deleting data, you need to understand what exactly occupies precious space. Redmi 5 owners are often surprised to find that the lion's share of memory is occupied not by photos, but by a messenger cache or forgotten video files. Standard conductor allows you to quickly assess the situation and identify the "eaters" of space.

To start, open the standard Explorer app and go to Analysis or Cleanup, the system automatically scans the device and lists categories: images, videos, apps, etc. Data visualization helps you instantly determine which folders have swelled to giant sizes.

⚠️ Warning: When analyzing memory, be careful with system files. Do not delete the contents of folders whose purpose you do not know, even if they take up a lot of space, otherwise this can lead to unstable work. MIUI.

Social media folders are worth paying special attention to. Viber, Telegram and WhatsApp have a habit of storing all received media files in the memory of the phone by default. Often in these directories you can find gigabytes of useless cards, old voice messages and watched videos that are duplicated in the cloud or simply not needed.

• 📂 Open the storage settings through the Settings menu → Memory for detailed statistics.
• 🔍 Use a file size search to find videos heavier than 100MB.
• 🗑️ Remove the Download folder, as installers often accumulate there. APK old documents.
• 📸 Check out the "Recently Deleted" album in the gallery, the files there still take up space.

After the initial analysis, you can make a plan of action. Often, simple file sorting by date can detect forgotten downloads from a year ago. Deleting just three to four long videos shot at 1080p resolution can free up to 2-3 GB of free space, which is a significant amount for Redmi 5.

Use of the built-in cleaning tool in MIUI

The MIUI shell features a powerful built-in system maintenance tool that many users ignore, preferring third-party applications.The standard Security utility has access to system partitions that regular cleaners cannot penetrate, and works more correctly with the Xiaomi file system.

Run the Security app and select Cleanup. The program will quickly scan and prompt you to delete temporary files, remnants of deleted applications and advertising debris. The process takes only a few seconds, but its effectiveness is high for daily use.

Inside the tool, there are additional tabs, such as Deep Clean, where you can find large files that were not seen in a quick scan, and there is also a memory cleanup feature in the background that frees up RAM, which indirectly affects the speed of the interface when there is a lack of disk space.

It's important to understand the difference between cleaning up your cache and cleaning up your data. Cache is a temporary file that speeds up your application load, can be deleted safely. Data is your logins, settings, and game progress. App data reset will return it to state immediately after installation.

• 🚀 Use the Acceleration button to close the background processes before cleaning.
• 📉 Check the “Recent Deletions” section within the Security app regularly.
• ⚙️ Set up automatic garbage cleaning when locking the screen in the utility settings.

Cache and application data management

The most voracious elements in a smartphone are social networks and instant messengers. Telegram and Viber cache all the media files viewed so that when you reopen the chat they download instantly. Over time, this cache can grow to 5-10 GB, which is a critical volume for Redmi 5.

You don't have to delete the app to manage this. Go to Settings → Apps → All apps. Find a heavy app (like Instagram or Chrome) and click on it. In the menu that opens, select Memory or Storage, and you'll see two buttons: Clear cache and Clear everything.

⚠️ Note: The Clear All button (or Reset) will delete your correspondence and login to the app, and only use it if you want to completely delete the program data or reinstall it.

Some apps, such as Telegram, have their own cache settings that are smarter than the system. Inside Telegram settings, you can set a cache size limit (e.g. 500 MB) or set up auto-delete media files older than 3 days, which automates the process and eliminates the need to do it manually.

Browsers also accumulate a huge amount of temporary files. If you are actively surfing the Internet, site cache, cookies and saved pages can take up a significant part of the memory. Periodic cleaning of the history and data of sites in the Chrome browser or standard MIUI browser is a mandatory procedure.

• 📱 In messengers, set up autodelete media files after a week.
• 🌐 Clear your browser cache after viewing “heavy” sites with a lot of ads.
• 📼 On YouTube and Netflix, delete uploaded videos if they are no longer needed.

Transfer applications and data to the SD memory card

Xiaomi Redmi 5 is equipped with a hybrid slot that allows you to use a microSD card with a capacity of up to 128 GB or more. This is a salvation for owners of the version with 16 GB of internal memory. SD-The map allows you to transfer photos, videos and even some applications to it.

By default, the system suggests using the card as "Portable Storage," which allows you to manually transfer photos and videos there, but for applications, the functionality is limited: many modern programs do not support porting to external drives for security and speed reasons.

You can format the card as "Internal Storage," in which case the system encrypts the card and combines it with the main memory, and the important thing is that after that, the card will not be read on other devices without formatting, and the data will only be available on this particular phone.

To transfer already installed applications, go to Settings → Applications. Select a program that supports portability (often games or older versions of applications). If the Move button is active, press it. If the button is gray, then the developer has banned the transfer, and you can not get around it without root rights.

Removal of duplicates and cleaning of gallery

The smartphone gallery is often the most cluttered place. Document screenshots, serial shots, failed shots and duplicates created during synchronization take up gigabytes. Redmi 5 owners need to regularly audit the media library.

The Gallery app has a built-in album called Screenshots, which often contains images of tickets, correspondence and confirmation codes that are only valid for a couple of days, and boldly delete the contents of this album once a month, and it's also worth checking out the Video album, as one video can weigh more than a thousand photos.

You can use third-party lightweight utilities to find duplicates or manually browse folders carefully. Often users don't notice that the same photo is stored in different folders (for example, WhatsApp and the main Camera folder), and duplicate files are one of the main reasons for the lack of space.

⚠️ Before mass deletion of a photo, make sure that important photos are stored in the cloud (Google Photos, Mi Cloud) or on your computer. Recover deleted files without backup on Redmi 5 is extremely difficult.

Also worth noting is the.thumbnails folder, which is a hidden system folder that stores thumbnails of images for quick display in the gallery, which can grow to the size of the originals over time, and can be safely cleaned through the file manager by enabling hidden file displays, but it will be recreated over time.

• 📷 Turn off photo saving in HDR-If you don’t use it to avoid doubles.
• 📉 Periodically clean the cart in Google Photos if sync is enabled.
• 🎞️ Remove the serial shooting, leaving only the best shot from the series.

Radical methods: Reset to factory settings

If none of the above methods have produced the desired result and the phone continues to signal a memory shortage, the last effective way is a complete reset. For the Xiaomi Redmi 5, this often becomes a “second birth”, as all system errors and accumulated debris are removed.

Before you do this, it is critical to back up all your data, reset everything: contacts, SMS, apps and files, use the built-in Mi Backup app to save data to your memory card or computer, and make sure your contacts are synced to your Google account.

💡

Use Mi Account to back up system settings and place icons on your desktop – this will save time setting up your phone after resetting.

To reset, go to Settings → About Phone → Reset. Select Erase All Data. The system will ask you to enter the screen unlock password and Mi Account password for confirmation. The process will take 5 to 15 minutes, after which the phone will turn on as new.

After reset, take your time to install all the apps at once. Set up your phone, check the amount of free memory and install programs only as needed. This will help keep the device clean longer. A clean system is much faster and requires fewer resources to maintain.

💡

Hard Reset is a last resort measure that returns the phone to a state out of the box, guaranteed to free up 100% of user memory.

Preventing memory overflow in the future

To prevent memory loss from returning to Redmi 5 in a month, you need to develop good habits. Prevention is always more effective than treatment. Regular monitoring of storage will help avoid critical filling of the disk, which leads to system freezes.

First of all, you can set up cloud sync for photos and videos. Services like Google Photos or Yandex.Disk can automatically upload new images to the Internet and delete them from the phone's memory, leaving only thumbnails, which creates the illusion that all the photos are on the device, but physically they are stored in the cloud.

It's also recommended that you limit the background activity of applications. Many programs continue to run in the background, accumulating data. Use the built-in MIUI battery limiter to prevent unnecessary applications from running in the background. This will not only save memory, but also increase battery life.

• 📅 Once a month, perform a quick cleaning through the standard application "Safety".
• 📉 Turn off auto-save WhatsApp statuses and Instagram stories in the gallery.
• ☁️ Set up automatic upload of heavy video to the cloud over Wi-Fi.

Remember that your smartphone’s internal memory is not designed to store archives. Keep only what you need right now. Careful handling of the file system will allow your Xiaomi Redmi 5 to remain fast and responsive even years after it’s released.
