How to Clean RAM on Xiaomi Redmi 8T: A Complete Acceleration Guide

Owners of the Xiaomi Redmi 8T smartphone often face a situation where the once-fashionable device begins to work slower, and applications stop keeping the background. This is a natural process for devices with a storage capacity of 4 GB, which over time overgrow cache and background processes. The MIUI system installed on board has its own features of resource management, which are not always obvious to the user at first glance.

Effective RAM cleaning isn’t just about swiping applications, it’s about optimizing CPU performance and resource allocation to active tasks. In this article, we’ll look at proven methods to help get your Redmi 8T back to speed without having to reset to factory settings. We’ll look at both the standard tools and hidden features that not everyone knows about.

Before we go into radical measures, it is important to understand what exactly eats free megabytes. Often the culprits are not only running programs, but also system services, in-front advertising, and aggressive energy saving algorithms. Competent setting will free up to 30-40% of resources, which is critical for comfortable use of instant messengers and navigation.

Standard cleaning methods through the settings menu

The easiest and safest way to free up resources is to use the built-in Security app. This is a system tool from Xiaomi that has deep access to the operating system processes. Run the application, find Memory Cleanup or Accelerate and press the Start button. The system will force the background processes that are not on the exception list to close.

However, standard cleaning is often superficial. For a deeper analysis, go to Settings → About Phone → Device Memory. Here you will see detailed resource allocation statistics. By clicking on the Clean button in this menu, you can delete temporary files that take up space in RAM, but are not visible when you normally close applications.

Importantly, after this procedure, the phone can run a little slower in the first seconds, because the system needs to reload the necessary services. This is normal behavior. Regular use of regular tools helps keep MIUI in good shape, especially on models with 4 GB of RAM, such as your Redmi 8T.

💡

Use the “Accelerate” widget on your desktop for quick access to clean up memory with one click, without going into the deep settings menus.

Don't rely on automatic cleanup scripts alone. Manually check the list of newly opened apps and close the ones you're definitely not going to use anytime soon, especially heavy apps like maps or social media that tend to inflate resource consumption.

Memory Extension (Memory Extension)

One of the key features in the latest versions of the MIUI shell is memory expansion technology. It allows you to use part of the permanent memory (ROM) as an additional RAM (RAM). For the Redmi 8T, this can be a salvation if you are short of the standard 4 GB. The feature is available via the Settings path → Additional → Expansion of memory.

When this option is activated, the system will create a special paging file, which will increase the total amount of memory available, but it should be noted that the speed of internal flash memory is lower than that of real RAM. Therefore, the performance gains in heavy games may be small, but multitasking in everyday tasks will significantly improve.

To activate the function, the following actions must be performed:

• 📱 Go to the settings menu and select About Phone".
• 🔍 Find a line with the version MIUI and click on it 7 times to unlock the developer menu (if hidden).
• ⚙️ Open "Memory Extension" and select the available amount (usually +2 GB or +3GB).
• 🔄 Confirm the action and wait for the device to restart for changes to apply.

Once turned on, the phone will automatically restart, and you'll notice changes in the task manager where the total amount of memory available increases, which is especially useful for those who keep many tabs open in the browser or actively use the navigator in parallel with music.

Managing Autoboot and Background Processes

One of the main reasons for the lack of RAM on Xiaomi is the large number of applications running with the system. Many programs prescribe themselves to autoload without the user's knowledge. To control this process, you need to activate the advanced developer menu. Go to Settings → About phone and quickly click 7-10 times on the MIUI version.

Once you have been notified that you have become a developer, go back to the main settings menu and select Additional → For Developers. Here we are interested in the Autoboot (or Download Services) section. Disable all applications that you do not need immediately after you turn on the phone. This will free up a significant amount of RAM from the first seconds of the device.

Also on the developer menu, you should pay attention to the background process limit setting. It's not limited by default. If you change it to "No more than 3-4 processes," the system will be more aggressive in unloading old applications from memory, making room for an active window. However, beware: this can cause the music to stop when you switch to another screen.

Remember that disabling system processes, the name of which you are not sure, can lead to unstable work Redmi 8T. It is better to be safe and leave the services associated with the system, Bluetooth and telephony.

Cleaning cache and removing "heavy" applications

Accumulated app cache is a hidden resource eater. Although the cache is designed to speed up programs, it can grow to giant sizes over time and take up space in RAM for indexing. Go to Settings → Applications → All applications. Sort the list by place you occupy.

Pay special attention to social networks and instant messengers such as Telegram, Viber or TikTok. They often store gigabytes of temporary files. Inside the settings of each such application, find the Clear Cache button. It is important not to confuse it with the Clear Everything button, as it will delete your logins and authorization data.

⚠️ Warning: Do not use third-party accelerators from the Play Market. They consume resources, display ads and often work less efficiently than embedded tools. MIUI.

For deep cleaning, you can use Recovery Mode. Turn off your phone, then press the Volume Up and Power buttons at the same time. In the menu that appears (volume button management, power button selection), select Wipe Cache. This is safe and will not delete your personal photos or contacts, but will clean up system debris.

If you rarely use any applications but don't want to delete them, consider freezing or disabling them. From the app menu, select an unnecessary program and click Disabling. It will disappear from the active list and stop consuming RAM until you manually turn it on again.

Using Developer Mode for Animations

The visual component of the MIUI interface also consumes processor and memory resources. Transition animations, opening windows and folding applications create a load. To make the interface more responsive on the Redmi 8T, you can reduce the scale of animations. This will not free up megabytes directly, but will unload the GPU and speed up the response of the system.

Go back to the developer menu we activated earlier. Find the section that's related to drawing or animation. You're interested in three things: "Window animation," "Jump animation," and "Duration of animation." Change their value from standard 1x to 0.5x or completely disable (No animation).

💡

Reducing the animations to 0.5x creates the illusion of a faster device and reduces the load on the GPU, which indirectly helps free up resources for background tasks.

Once you've set up the settings, you'll notice that the menus are opening instantly, and this is especially true for budget and mid-budget models, where every bit of the CPU counts, and when combined with cleaning up RAM, it gives you a tangible performance boost.

Also on this menu, you should look for the option of GPU rendering, make sure it's on, which will force the system to use the power of the graphics chip to render the interface, unloading the CPU and freeing up the streams to process data in memory.

Radical measures: Resetting and optimization

If the software methods don't work, there may be some errors or version conflicts in the system, in which case a full factory reset helps. Before that, be sure to back up your data via Mi Cloud or your computer, as all files will be deleted. Settings → The phone. → Resetting settings.

After reset, take your time to install all the applications at once. Install only the necessary and observe the memory behavior for a couple of days. Often the problem lies in one particular application that is not working correctly with your version of MIUI. Gradual installation will help identify the culprit.

⚠️ Before resetting, make sure that the battery is at least 60% and the device is connected to a stable Wi-Fi network so that the process goes smoothly.

Also consider installing custom firmware (like Pixel Experience or LineageOS) if you’re an advanced user, which lacks Xiaomi’s heavy add-ons and consumes significantly less RAM, but this action will take away your warranty and require technical skills.

Regularly restarting the device is another simple but effective method: Don’t keep the phone on for weeks. Reboot the Redmi 8T once every 2-3 days. This clears system logs and resets the frozen processes that may have been stuck in memory.
