How to Clean Up Xiaomi Phone RAM: The Complete Guide

Modern Xiaomi smartphones running MIUI shells or the new HyperOS have powerful hardware, but even flagship models eventually start to run slower. The main reason for the performance drop is often overcrowded RAM (RAM). When free resource runs out, the system begins to aggressively unload background processes, leading to delays when switching between applications and slowing the interface.

Many users mistakenly believe that the standard Clean button in Task Manager solves the problem dramatically. However, Android algorithms are designed to instantly fill the freed memory with newly launched services. Proper cleaning requires a comprehensive approach: from setting system constraints to using special developer modes. In this article, we will examine not only fast methods, but also the deep settings that really affect performance.

It’s worth noting that RAM isn’t just a number in the characteristics, it’s a dynamic buffer for your data. The more apps you keep open, the more resources you need. If your Xiaomi is starting to think about entering heavy games or cameras, that’s the first sign that memory management is out of control.

Standard cleaning methods via MIUI and HyperOS interface

The most obvious and affordable way to free up resources is to use a built-in security tool, which Xiaomi’s Security app is responsible for, despite criticism from power users, it can correctly complete processes that have not been used for a long time without affecting systemically important services.

To do a quick cleaning, you need to run the Safety app and press a large green lightning button, and the system will analyze the current state and force the background applications to close, but this method only has a short-term effect. More effective is manually controlling running programs through the multitasking menu.

💡

Press and hold the Menu button (a square or three bars at the bottom of the screen) to open the extended multitasking menu where you can close all applications with one swipe or selectively.

In the new versions of the HyperOS shell, the memory mechanism has been redesigned, and now the system tries to anticipate your actions and loads frequently used applications into the memory cache in advance, and if you want to forcefully reset this cache, you can use the following sequence of actions:

• 🚀 Click the Open Applications menu call button.
• 🧹 Find the broom or cross icon in the corner of the screen (location depends on the topic).
• 🛑 Click on “Close Everything” to instantly complete the processes.
• 🔄 Restart the device to completely reset system temporary files.

It is important to understand that manual zero cleaning can even damage autonomy, as the system will have to re-run heavy processes from scratch, consuming more CPU power.

Configure extended memory and virtual RAM

One of the key features in modern Xiaomi smartphones is the technology of expanding RAM, which allows you to reserve part of the built-in storage (ROM) and use it as an addition to the main RAM. This is especially true for models with 4 or 6 GB of RAM, where the lack of resources is felt more severe.

To activate or configure this feature, go to Settings → Additional Settings → Expansion of memory. Here you will see the available volume that can be redistributed. Usually you will choose between 2, 3 or 4 GB (depending on the model).

⚠️ Note: Using the memory extension function increases the load on the built-in drive. On older or badly worn devices, this can lead to accelerated wear of flash memory and reduce the overall read/write speed of data.

The technology works by creating a paging file, where when physical RAM is filled, the system starts dumping data from inactive applications there, which prevents them from completely shutting down, allowing them to return to the application faster when they are restarted, but the speed of virtual memory is still lower than with physical LPDDR4X or LPDDR5.

So if you see that the interface is less responsive, even though there are a lot of applications open, you'd better turn off the extension or reduce the size of it. For most use cases, a minimum of 2 GB is enough.

Using Developer Mode to Optimize

For advanced users who want to gain maximum control over how Xiaomi manages resources, there is a Developer Menu, which has parameters that affect background limits and caching. → About the phone and quickly pressing 7 times on the item "Version" MIUI» (or "Version" OS»).

Once you activate the developer menu, look for the memory section, and we're interested in the "Background Process Limit" section, which is the default, but it's possible to change it, and it's also useful to look at the animation settings, because they visually affect how you perceive the interface's speed.

Here is a list of options that are worth checking for optimization:

• 🔧 Background Process Limit: Set a value of “No More than 4 Processes” if you have few processes RAM.
• 🎨 Animation scale: reduce to 0.5x for a sense of greater interface sharpness.
• 📉 Do not save activities: do not turn on this feature constantly, it is designed to debug applications.

Changing these settings requires caution: Aggressively restricting background processes can disrupt messengers (messages will arrive with a delay) and navigators, and optimally use these settings temporarily when you need to run a resource-intensive game or a heavy application.

Identify and remove hidden users of resources

Often, when RAM is occupied by nothing, it is caused not by system processes, but by poorly optimized applications or hidden mining. Some programs may disguise themselves as system services or simply incorrectly free resources after use.

Go to Settings → Advanced Settings → Usage Statistics (the path may vary depending on the Android version). Here you can see which apps have consumed the most resources in the past 24 hours or 7 days. If you see an unfamiliar app at the top of the list, that's cause for concern.

Also, it's worth checking the boot list. MIUI There is a special section of the appendix → Permits → Autorun. Turn off all unnecessary programs here. Not only will it save RAM, it will also extend battery life.

Special attention should be paid to the “live wallpaper” and widgets on the desktop. Beautiful particle animation or constantly updated news feed eats up a significant chunk of RAM. If your smartphone has started to slow down, try temporarily installing a static black image as wallpaper and remove the widgets.

Specialized tools and Game Turbo

In the Xiaomi ecosystem, there is a built-in Game Turbo mode (formerly known as Game Center), which is not just a launcher for games, but a powerful tool for managing system resources. When you run a game through this mode, the system redistributes priorities, giving maximum CPU and RAM to the gameplay.

In Game Turbo settings, you can activate Memory Acceleration, and the algorithm forces all background processes except system processes to unload, creating a clean environment for the game, avoiding micro-freezes and crashes in heavy projects like Genshin Impact or PUBG Mobile.

Beyond gaming tools, there are third-party utilities that can help monitor. However, on Android, third-party memory cleaners often perform worse than built-in ones, as the system itself tends to close them, and it’s better to use proven tools like SD Maid or built-in storage analyzer to find files that occupy space, indirectly affecting swap files.

Radical measures: Resetting and reflashing

If none of the software methods worked and the phone continues to suffer from memory shortages even after a reboot, it may be that the problem lies in deep file system errors or conflicts after an update, in which case a full factory reset helps.

Before doing this, be sure to back up your data to the Mi Cloud or your computer, as all user files will be deleted.Reset will return the memory partitions to their original state, removing fragmentation and accumulated software debris.

⚠️ Warning: Do not interrupt the reset or flashing process. A discharged battery or phone shutdown during partition formatting may result in the inability to boot the system (bootloop) and require recovery via a computer.

Don't install all applications at once after reset, turn them on gradually by observing the behavior of the system, which will help identify the "culprit" of a memory leak if the problem was caused by a particular application. Often users forget that old backups can return software errors.

💡

A full reset is an extreme, but often the only, measure to fix memory management software errors accumulated over the years.
