How to Clean RAM on Xiaomi Redmi 8

Owners of the popular budget smartphone Redmi 8 often face a situation where the device starts to run slower and applications open with a noticeable delay. This is a typical scenario for Android gadgets that are used for more than a year without deep optimization of the system. The device’s RAM is overflowing with background processes, cache and residual files, which directly affects the performance of the interface. MIUI.

Fortunately, MIUI has powerful maintenance tools that help you get your phone back to its original sharpness. In this article, we’ll look at not only the standard cleaning methods, but also the hidden settings available to power users, how to manage running processes properly and whether you should use third-party utilities to speed up your Xiaomi.

Standard cleaning products through the Security app

The easiest and safest way to free up the system is to use the built-in Security application, which is deeply integrated into the MIUI shell and has access to system processes that are not available to third-party programs, and to start working, you need to run the application through the main screen or the Tools folder.

Once you open it, you'll see a circular indicator that shows the current memory load, and clicking on the Clean or Accelerate button will trigger an automatic algorithm that will force the background applications to close and clear the temporary files, and the system will determine which processes can be safely completed without losing user data.

However, it is worth noting that standard cleaning is often superficial, it closes only visible applications, but does not always unload from the surface. RAM Google heavy services or system services MIUI, which consume a significant amount of resources.

• 🚀 Click the “Speed Up” button to instantly close active applications.
• 🗑️ Use the Cleanup tab to remove system debris and cache.
• ⚙️ Go to the application settings to adjust the scan depth.

⚠️ Warning: Do not use Accelerate too often in the hope of extending battery life. Constantly unloading applications from memory causes the processor to restart them, which increases energy consumption.

Memory Extension (Memory Extension)

One of the key features of modern versions of MIUI is Memory Extension technology, which allows you to use part of the permanent memory for RAM. For owners of Redmi 8 with a capacity of 2 or 3 GB of RAM, this is a critical feature that can significantly improve multitasking.

To activate this mode, go to the phone settings, select the Additional section and find the Extension of Memory. Here you can redistribute space by taking, for example, 2 GB from the file storage and giving them to the system needs, after turning on, you will need to reboot the device.

It is important to consider that virtual memory is slower than physical RAM. Therefore, performance gains will be noticeable mainly when switching between heavy applications, not in games. However, for everyday tasks, this is a great way to reduce the number of “downs” of applications from the background.

⚠️ Warning: Activating the memory expander reduces the available space for photos and videos. Make sure you have at least a little space. 4-5 GB before activation.

Managing Autoboot and Background Processes

Many Android apps tend to start right after the phone is turned on and continue to hang in the background, consuming precious megabytes. MIUI has a special section that allows you to tightly control this process and prohibit unwanted start services.

To access these settings, you need to go to the App section of the Settings menu, then select Permissions and then Auto Run. Here you will see a list of all programs that start with the system. Disable anything that is not critical, such as instant messengers (if you do not need constant notifications) or stores.

You should also check the settings for each specific application. Go to Apps → All apps, select the right one, click Other permissions and disable Auto Run. This will prevent hidden resource consumption in the background.

• 🛑 Turn off auto-start for games and rarely used utilities.
• 🔔 Leave only messengers and email clients included.
• 🔋 Limit background activities to save battery power.

Cleaning the cache and removing residual files

Over time, a smartphone accumulates a huge number of temporary files that create applications for fast downloading content, which can take up hundreds of megabytes and even gigabytes, slowing down the file system and taking up space.

Clear the cache selectively for each application through the App menu → All Apps → [Selected App] → Memory → Clear the cache. Don’t confuse this feature with the Clear All button, which will delete your logins and data inside the app.

It is also recommended to regularly delete folders with residual files from remote programs. You can use the built-in File Manager Explorer by going to the folder. Android/data, or use the deep cleaning function in the application "Safety».

Regular file system maintenance helps to maintain high speed reading and writing data, which is especially important for low-cost processors installed in Redmi 8.

💡

Tip: Cache of cards (Google Maps, Yandex.Maps) and instant messengers (Telegram, WhatsApp) grows fastest. Clear them separately once a month through the settings of the applications themselves in the section "Data and memory".

Comparison of Memory Cleaning Methods

There are many ways to optimize your smartphone, and each has its own features, advantages and disadvantages, and understanding the difference between them will allow you to choose the most effective maintenance strategy for your device depending on the current situation.

Below is a comparative table of basic techniques that will help you navigate which tool is best used to address a particular productivity or resource shortfall.

Using Developer Modes for Advanced Users

For those who want to take full control of the system, there is a Developer Options menu. It's hidden by default, but activating it opens up access to the subtle animation settings and limits of background processes, which can visually speed up the interface.

To turn on the menu, you need to quickly click 7 times on the build number in the About Phone section. After the "You became a developer" notification appears, a new section will appear in the settings menu, where you can find the background process limit and limit their number, for example, to 2-3 pieces.

Also in this section, you can turn off or scale down the animations of windows, transitions and animator duration. This will not free up physical memory, but will make work with the Xiaomi interface more responsive and faster in appearance.

⚠️ Warning: Changing the settings in the developer menu can cause some applications to run unstable or to unexpectedly close background tasks.

💡

Combining limiting background processes and turning off animations gives a better visual acceleration effect on older devices than simple RAM cleaning.
