How to Free Memory on Xiaomi Redmi 8T Phone

The Redmi 8T, launched in 2019, is still a popular device thanks to its excellent value for money and energy-efficient processor. However, over time, owners face a lack of free space, which leads to slowdowns and the inability to install new applications. Internal storage of 64 or 128 GB can quickly be filled with system logs, messenger cache and high-resolution media.

The MIUI operating system installed on the device has powerful built-in tools for managing files, but they do not always work automatically as the user would like. Understanding the structure of folders and knowing the hidden functions allows you to radically increase the available space without losing important data. In this guide, we will discuss proven methods that will help you return performance to your gadget.

Don't ignore the system's space-scarcity signals, as a crowded /data partition can lead to unstable phone performance and even cyclical reboots. Timely cleaning is not just about removing a photo, but about a comprehensive approach to maintaining a device's flash memory. Let's start by analyzing what exactly takes up space.

Analysis of vault occupancy

Before you can delete files, you need to know exactly what data is taking up the lion's share of the space. There's a built-in analyzer in the MIUI shell that visualizes the file categorization. Go to the settings and look for Warehouse to see a detailed memory occupancy chart.

The system will show that applications and their data are usually the most space-consuming, as well as the “Other” section, which often hides forgotten downloads and browser cache. Storage analytics allows you to quickly identify heavy files that you may not even remember. Without this step, cleaning may not be effective.

Pay attention to the size of the Apps section, as modern programs, especially social networks, can grow to several gigabytes. Android stores temporary data to speed up work, but over time this cache becomes redundant. Regular monitoring helps keep things under control.

If you see that the Other category is taking up a suspiciously large amount of space, it may indicate the presence of residual files from remote programs or corrupted downloads, in which case it is recommended to use specialized tools to find duplicates and empty folders, accurate analysis is the first step to success.

A visual diagram in the storage settings is the best way to understand where the free space goes before you start cleaning.

Use of the built-in "Security" application

All Xiaomi smartphones have a Security system app preinstalled, which includes a powerful Cleanup module that scans the device for temporary files, advertising debris and remnants of remote applications. Launching deep cleaning takes only a couple of minutes, but can free up 500 MB to several gigabytes of space.

It's important not just to click the "Clean" button, but to carefully study the proposed categories for removal. In the section "Cache Cleanup" often are thumbnails of images and temporary browser files, the removal of which is safe for the system to work, but be careful with the section "Big files", where important documents may lie.

The Acceleration feature in the same application helps free up RAM by closing the background processes that consume CPU resources. While this does not increase storage space directly, it improves overall interface responsiveness, which is especially true for the Redmi 8T. Regular use of these tools extends the life of the device.

In the Security settings, you can enable automatic cleaning, but you can control the process manually so that you don't accidentally delete the data you want. The system itself tells you which files are safe to delete by labeling them in green. Trust in MIUI system utilities is often justified, because they know the structure of the third-party system better.

Use the Deep Clean feature in the Security app once a week to remove hidden temporary files that are not visible during normal browsing.

Cleaning the cache of messengers and social networks

The most voracious apps on any Android smartphone are messengers like Telegram, WhatsApp, and Viber. They store every photo, video, and voice message they see into the device’s memory, creating giant archives of data. Over time, a folder with media files can take up more than half of Redmi 8T’s total available memory.

In Telegram, you can clean up through settings: go to Settings → Data and memory → Use memory and click Clear cache. The uniqueness of this messenger is that deleted files from the cache remain on the server and re-download if necessary, without taking up space on the phone, this is the most effective way to combat space shortage.

WhatsApp is more complicated because media files are often duplicated in the gallery, you go to the chat or storage settings inside the app and select the chat rooms that take up the most space, you can delete the videos and gifs, leaving text messages intact.

⚠️ Before mass cleaning of the messenger cache, make sure that important documents and photos are stored in the cloud storage or on the computer, as it will be impossible to restore the deleted cache without the Internet.

Social networks like Instagram and VK also accumulate a huge amount of temporary data. These apps often don't have a built-in button for full cache clearing, so you have to go to the settings of Android itself. Find the app in the installed list, click Storage and select Clear Cache, but not Clear Data so that authorization doesn't fly.

Regularly reviewing subscriptions and groups, where you get a lot of media content, will also help reduce the speed of filling up memory. Disabling auto-save incoming files to the gallery is another important step. Control over messengers gives instant results in the form of gigabytes of free space.

File management and removal of duplicates

Xiaomi’s standard file manager Explorer makes it easy to sort files by type and size. Often, the Download folder accumulates.apk installation files from updated applications that are no longer needed. Deleting these files is safe and frees up space.

Special attention should be paid to the DCIM folder, where your photos and videos are stored. Videos in 1080p or 4K resolution can take up hundreds of megabytes each. If you don't plan to store everything on your phone, move the archive to your computer or to the cloud. Duplicate photos are also common if you used different cameras or sync.

You can use third-party tools to find duplicates, but often you just need to manually go through Screenshots and WhatsApp Images folders. Many users forget that screenshots of interfaces and correspondence take up space for years. Removing old visual noise will not only free up memory, but also speed up the gallery.

Use the size sorting function in the file manager to see the heaviest files right away. Often it turns out that a forgotten movie or screen recording takes 2-3 GB. The Android file system allows you to quickly move such files to a memory card if your Redmi 8T has the appropriate module installed.

💡

Sorting files by size is the fastest way to find “hidden memory eaters” that aren’t visible in a standard repository review.

Removal of applications and rights management

Xiaomi devices often have a lot of apps pre-installed that you may not use. Some can be removed completely, others can only be disabled. Go to Settings → Apps → All apps and study the list carefully.

Removing heavy games and unused services is an obvious step, but you should also pay attention to System Apps, for example, if you do not use Mi Video or Mi Music, their cache and data can be cleared, and the applications themselves can be limited in background activity, which will reduce the load on the processor and memory.

Under Advanced Settings, you can find the access rights menu. Turning off background activity for rarely used programs will prevent them from accumulating temporary data. Android allows you to freeze applications, which is equivalent to deleting them, but with the ability to quickly restore them.

⚠️ Note: Do not remove system applications that you do not know the purpose of (such as Google Play services or components) MIUI), This can lead to unstable operation of the system or loss of functionality.

Also check which apps have auto-run permissions. MIUI has a separate Auto-Run menu where you can leave only messengers and the rest is banned, which will prevent hidden resource consumption immediately after the phone is turned on.

Use of cloud storage and memory cards

If Redmi 8T's internal memory is no longer enough, the smartest solution is to use cloud technology: services like Google Photos allow you to store media files in the cloud, leaving only thumbnails on the device, and when you view the photo, it loads in its original quality, but does not occupy space.

Setting up automatic synchronization of folders with photos and documents in Google Drive or Yandex.Disk will help keep local storage free. Once you successfully upload files, you can delete them from your phone using the “Free Space” feature in the cloud service application, which is a modern approach to data management.

Redmi 8T supports microSD card installation. You can transfer all photos, music and videos there, leaving internal memory for applications only. In storage settings, select the memory card as the default recording location for the camera and voice recorder.

Hybrid storage allows you to combine internal memory speed with external storage capacity. Applications will run fast, and your archives will not interfere with the system. Remember to periodically check the memory card for errors through the storage settings menu.

Regular maintenance of the Redmi 8T using the described methods will allow you to forget about the problem of space shortage. The combination of manual cleaning, smart system settings and cloud technology gives the best result. Your smartphone will work as new even after years of use.
