How to Clean RAM on Xiaomi Redmi 9T: The Complete Guide

Modern smartphones like the Xiaomi Redmi 9T have a lot of RAM, but over time, even powerful devices can experience slowdowns in the interface, because the Android operating system and the MIUI shell accumulate background processes that consume resources. Users often notice that apps start opening longer and switching between tasks is delayed.

Effective memory cleaning (RAM) allows you to instantly free up resources for active applications and games. Unlike built-in storage where your photos and videos are stored, RAM works with data in real time. Proper management of this resource on Redmi 9T extends battery life and ensures smooth animations.

In this guide, we’ll break down the system’s regular tools, hidden developer settings, and third-party optimization methods. You’ll learn which processes can be safely completed and which ones are best left alone for the system to work properly. A sound memory management approach will turn your smartphone into a more responsive tool.

Standard cleaning tools in the shell of MIUI

The MIUI shell installed on Redmi 9T offers a built-in optimization engine that is available in one click. To activate it, you need to find the Security app with the green shield icon, which is the system control center. Inside this application is the Cleanup function, which scans the system for temporary files and loading processes.

Pressing the clean button triggers an algorithm that forcibly closes the background applications and removes the cache of system services. RAM is released instantly, which is especially useful before running demanding games or navigation. However, it is worthwhile to understand that the system will automatically refill the vacated space with the necessary services after a while.

Additionally, the Security menu features a section called Acceleration, which visually shows the load on the CPU and RAM, where you can manually choose which applications to close if you don't want to rely on automatic system selection, giving the user more subtle control over running processes.

• 🚀 Click on the Security shield icon on your desktop.
• 🧹 Select “Clean” and wait for the scan to be completed.
• 🛑 In the Acceleration section, manually close unnecessary background tasks.
• ⚙️ Check the Battery section regularly to find energy-intensive applications.

⚠️ Warning: Constant manual memory cleaning through third-party “task killers” can lead to unstable work MIUI, The system will constantly try to restart important services.

💡

Use the Cleanup widget on your desktop for quick access to the acceleration feature without logging into the settings menu.

Managing Autoboot and Background Processes

One of the main reasons for the lack of free RAM on the Xiaomi Redmi 9T is the large number of applications running with the system. Many programs prescribe themselves to autoboot to send notifications instantly, even if you rarely use them.

To manage this setting, you need to go to advanced settings. Settings → Applications → Auto Run displays the full list of programs that start automatically. It is recommended to leave only messengers and system services on, and turn everything else off.

Also worth paying attention to the function “Memory Extension”, which uses part of the internal storage as a virtual RAM. While this sounds useful, on models with fast main memory, disabling this feature sometimes gives a more stable response to the system, since the speed of the built-in drive is lower than the speed of real RAM.

After making changes to the boot list, the system may require a reboot to apply settings.This is normal behavior that ensures that disabled services are not started again until the next start. Regularly reviewing this list helps keep the smartphone in good shape.

Using Developer Mode to Limit Processes

For advanced users who want to get maximum control over Redmi 9T, there is a hidden menu “For developers”. activation of this menu requires several clicks on the build number in the “About phone” section. After activation in the main settings, a new item appears, allowing you to strictly limit the number of background processes.

In Settings → Advanced Settings → For developers, you need to find the item “Background Process Limit.” By default, the system decides how many applications to keep in memory, but here you can set a limit, for example, “No more than 2 processes”, which will force the system to unload old tasks from RAM.

Using this tool requires caution, and if you set a limit that's too tight, messengers can stop coming on time, and music players can stop when they switch to other screens, and it's a powerful tool for situations where you need to start a heavy game, and all the power must be given to one application.

And you can find the same menu called "Do Not Stay Activated," which destroys the app immediately after you leave it, and it's a radical cleanup method that's guaranteed to free up all the resources, but makes multitasking impossible.

Analysis of memory consumption by different applications

Not all apps consume resources equally, and on the Xiaomi Redmi 9T, it is important to be able to identify “voracious” programs. Social networks such as Facebook or Instagram often consume significantly more RAM than their functionality requires. Analysis of statistics helps to understand which programs slow down the smartphone.

In Settings → Memory (or through the developer menu, Running Services), you can see detailed statistics, which shows how many megabytes each application takes up and how long it lasts in the background, and if you see a program that hasn't been used for several days, but it eats hundreds of megabytes, it should be deleted or cleared.

Special attention should be paid to the system process Media, which is engaged in file indexing, if it consumes a lot of resources constantly, it may be stuck in memory of a corrupt file or is in the process of updating the system, in which case it helps to clean the cache of media services through the application menu.

Regular monitoring of these metrics allows you to quickly detect anomalies, and if a regular application suddenly starts consuming gigabytes of memory, this is a signal that a malfunction or need to update.

💡

Social media is the main consumer of memory; use their lightweight versions (Lite) if you are experiencing a shortage of resources.

Cleaning cache and temporary files

Although the cache is designed to speed up applications, its growth to a giant size can negatively affect the performance of the Redmi 9T. Temporary files take up not only built-in storage, but can fragment the work of RAM when you access them.

You can do this through the already familiar Security app or manually for each application. From the Settings menu → Apps → All applications, select the desired program, go to Memory and click Clear Cache. Don't confuse this button with Clear Everything, as the second option will delete logins and settings.

There is also a hidden system utility for deep cleaning, so to run it, open the Phone app and type ##6484## (engineering menu) or use the command via ADB for advanced users, but for most cases, regular cleaning tools are enough.

• 🗑️ Clean your browser cache regularly, as it grows the fastest.
• 📸 Check the camera cache and galleries if you are actively shooting videos in the video. 4K.
• 📱 Clear the cache of app stores (Google Play, Mi Store) when downloading errors.

After the cache is cleaned, the first application launch may take a little longer, as the system will have to recreate the necessary temporary files, an expected behavior that will quickly normalize.

System restart and maintenance

The easiest but often ignored way to free up RAM is to completely reboot the device. Unlike turning it off and on, rebooting completely clears RAM, resets all system errors, and stops the hanging processes. For the Xiaomi Redmi 9T, it is recommended to do this at least once a week.

Modern versions of MIUI have a "Planned Reboot" feature that allows you to set up automatic switching off and on of your smartphone, for example, at 3 a.m. when you sleep, which ensures that the device will work at its maximum speed in the morning.

If a simple reboot doesn’t work and the memory fills up instantly, consider resetting to factory settings, which is an extreme measure that cleans the phone completely, returning it to the “out of the box” state.

⚠️ Warning: Resetting to factory settings will permanently delete all photos, contacts and apps. make sure you have an up-to-date backup.

Once reset, the system will work as quickly as possible, as the accumulated “digital waste” will disappear over the years, but over time, as the applications are installed, this may happen again, so it is important to monitor the hygiene of smartphone use.
