How to Clean RAM on Xiaomi: The Complete Guide

Modern Xiaomi smartphones running MIUI or HyperOS shells have powerful hardware, but even flagship models can start to work slower over time. The main reason for the performance decline is often overflow of RAM, which temporarily stores data from running applications and system processes. When free space runs out, the device begins to hang up, and background programs close on their own.

Users often confuse RAM with internal memory for storing files, but cleaning RAM is critical to the speed of the interface. Android and its add-ons from Xiaomi can manage resources independently, but in intensive use, manual intervention or competent adjustment can give a tangible increase in speed. In this article, we will discuss proven ways to free resources without using third-party junk software.

Before we start taking any drastic measures, it's important to understand which processes are consuming the most resources right now, which will allow us to not just blindly clear the cache, but to specifically address the causes of the brakes. Next, we'll look at the standard tools of the system, the hidden functions of the developer and the nuances of virtual memory.

Use of the built-in MIUI accelerator

The easiest and safest way for every Xiaomi smartphone owner to use is the regular “Security” app, which is pre-installed on all the brand’s devices and has direct access to the system cleaning processes. To start the procedure, you just open the application, which usually has a green icon with a shield, and click on the large Clean or Accelerate button depending on the firmware version.

Once scanned, the system will show how many megabytes or gigabytes have been released, but standard cleaning often only affects the surface cache. For more in-depth work, you need to go to the Memory section inside the Security app, which displays detailed statistics on RAM usage and a list of the most "heavy" applications that can be forcibly stopped.

💡

For instant access to cleaning, add the "Acceleration" widget to the main screen - this will free up memory with one touch, without opening the settings menu.

It’s worth noting that persistently aggressive memory cleaning with built-in tools can backfire. Android is designed to keep frequently used applications in memory to run them quickly. If you continually unload all processes, the processor will have to restart them, leading to increased battery consumption and short-term lags immediately after cleaning.

⚠️ Warning: Do not install third-party software from the Play Market (like Clean Master and its peers) on modern Xiaomi. MIUI, causing endless cleaning cycles and loading the processor even harder.

The efficiency of the standard accelerator depends on the version of the shell. On new versions of HyperOS, the memory algorithms have been changed, and manual cleaning is less often required. If the standard button does not give a visible result, then the problem lies deeper in specific applications or system settings.

Forced Stop and Application Management

Often, the reason for the lack of free RAM is not system processes, but specific applications that do not work correctly in the background. Social networks, messengers and marketplaces can eat gigabytes of RAM, even if you are not using them right now. To identify the culprit, go to the Settings menu, then select the App section and click All apps.

In the list that opens, sort programs by memory size, or just analyze those that you rarely use. When you go inside a particular application card, find the Stop button. This action will force the process to close and free up the memory it occupies. For system applications, this button may not be available, which is normal protection of system integrity.

• 🚀 Social media (VK, Telegram, Instagram most often require a forced stop, as they constantly update the feed in the background.
• 🛒 Store apps (Ozon, Wildberries, AliExpress) are often “hang” in memory after completing purchases, they can be safely closed.
• 🎮 Gaming launchers and heavy games may not close completely after the release, leaving debugging processes hanging.

After stopping applications, it is also useful to clear their cache by clicking the corresponding button in the same menu. This will not delete your logins or correspondence, but will remove temporary files that could inflate the amount of memory you take. Regularly checking this partition helps keep the smartphone in good shape without the need to restart.

Extended memory (Virtual RAM)

Modern Xiaomi, Redmi and POCO models have a feature called "Memory Extension" that allows you to reserve some of your internal flash memory and use it as an addition to your RAM, and it works like a swap file in Windows, where the least-used data is unloaded from the fast RAM to the slower but larger internal memory.

You can activate this function in the Settings menu → Additional → Expansion of memory. Here you will be asked to select the amount of memory you add, for example +2 GB, +4 GB or more, depending on the device model. Once you change the settings, the smartphone will be sure to ask you to reboot so that the changes take effect.

Should you include this feature? If you have a budget model with 4GB or 6GB of physical memory, then the expansion will definitely help keep more applications open. However, on flagships with 12GB and 16GB of RAM, enabling virtual memory can even reduce overall system responsiveness due to the difference in read and write speeds.

Developer Options for Advanced Users

For those who want to have full control over how the system manages resources, there is a Developer Menu. To activate it, go to Settings → About Phone and quickly click on MIUI or HyperOS seven times. Once a successful activation message appears, a new option will appear in the settings menu.

In the Applications section, we're interested in the Background Process Limit setting, which is set to Standard Limit by default, but can be changed by limiting the number of applications running simultaneously in the background, for example, choosing No More than 2 Processes will force the system to aggressively unload all the extra.

• 🔧 The “Do Not Stay Activated” option is useful for testing, but in everyday life it will make working with your phone uncomfortable.
• 🔧 Disabling window caching can visually speed up the interface, but will increase the CPU load every time you open the application.
• 🔧 The function "Running Services in the background" allows you to completely ban background activity for all programs, which will critically affect the receipt of notifications. ⚠️ Warning: Changing the settings in the developer menu can lead to unstable system operation or loss of important notifications from messengers. It is recommended to change only one setting at a time and monitor the behavior of the smartphone. Also in this section, you can find the Download Services feature, which shows which system services are consuming memory right now, which is a great diagnostic tool to help you identify hidden system errors that are not visible in a normal task manager. Memory usage analysis and leak detection Sometimes memory leaks due to software errors, when the application consumes resources but does not release them after closing. In the Phone app, dial ##6484## to enter the engineering menu. CIT. Select the version or memory option to see the technical statistics. An easier way is to use the Statistics menu in your battery or memory settings. Notice the RAM usage schedule for the last 24 hours. If you see a sharp spike or constant high consumption when the phone was lying idle, it is a sign of memory loss. Often the culprits are weather widgets, live wallpaper or poorly optimized games. 📊 How often do you reboot your Xiaomi?Once a day:Once a week:Only when it starts to brake:Never, use months Regular monitoring helps to understand usage habits.If memory is filled immediately after turning on, it is worth checking the autoload of applications. In Xiaomi, this feature is hidden in permission settings or in the menu "Advanced settings" → "Autostart". Disabling autostart for unnecessary programs will significantly reduce the initial load on the system. Reboot and maintenance The oldest and proven way to clear RAM is to completely reboot the device. Unlike turning off and on the screen, rebooting completely deactivates the memory chips and resets all temporary data. It is recommended to do this at least once a week to maintain the stability of Android. In addition, the settings, there is a function "Planted on and turn off the device in the morning, you can reboot it on the computer, for example, it will be rebooted on the 3 hours. "For example, Xiaomi, you can reboot on the computer, you will reboot you will reboot on the computer, it will be reboot you in the computer. Even if the memory is still occupied after rebooting 80-90%, Maybe it's time to check your phone for malware or remove long-overdue apps, sometimes by cleaning the "Other" partition into storage, which indirectly affects the speed of RAM, as the system does not have enough space to create temporary paging files. 💡Regularly restarting once a week is more effective than daily manual cleaning and prolongs the stable operation of the system without third-party software (FAQ) Does filling up internal memory affect the speed of RAM? Yes, it affects indirectly (ROM) fuller 90%, The system has no place to create temporary files and use swap mechanisms, which can lead to general lags, which the user perceives as a lack of RAM"? In modern versions of Android and MIUI, this is not necessary for background applications. The system itself knows how to freeze them. You only need to close programs that are stuck or behave incorrectly. Constantly closing all applications only consumes the battery. Why does it re-stock after cleaning the memory in a minute? This is normal behavior of Android. The system preloads frequently used applications to free RAM to run them instantly. Empty RAM in Android is considered useless, so the system seeks to fill it with useful data. Can antiviruses load RAM? Yes, some antiviruses with active real-time protection can only consume significant resources from the built-in antivirus application, and the installed in the second one is usually enough antivirus. Resetting to factory settings helps if nothing works? A full reset (Wipe Data) is a radical but effective measure. It removes all apps and settings, returning the phone to its original state. Before this procedure, make sure to back up important data to the cloud or to your computer.
