Xiaomi smartphones are famous for their performance, but over time, even powerful flagships begin to slow down. The main reason for the decline in performance is often overcrowded RAM. When the system lacks resources to process background processes, the MIUI or HyperOS interface begins to react with a delay, and applications can fly out or restart.
RAM cleaning is not just about removing cache, it's about optimizing your system. In this article, we'll look at not only the standard methods that are available to everyone, but also the advanced settings that are hidden in the developer menu, and how to manage the device's resources properly so that it works as new.
It's important to understand the difference between a storage device and RAM, because the methods of cleaning it are very different. If you want your Redmi or Poco to fly, you need to prioritize your processes properly, let's figure out what tools the shell itself offers and where hidden reserves lie.
β οΈ Warning: Cleaning all processes immediately after the phone is turned on may lead to a temporary decrease in autonomy, as the system will have to restart the necessary services.
Built-in MIUI and HyperOS optimization tools
The easiest and safest way to free up resources is to use the regular Security app. Unlike third-party cleaners, this tool has deep system access rights and knows what processes can be completed without compromising stability. Launch the app and press Clean up or Accelerate.
The system will automatically analyze the current state and suggest closing the background applications, but it is worth noting that the forced termination of all processes is not always effective. Android is designed so that frequently used applications run faster from memory than from scratch, so you should use the feature of selective cleaning.
- π± Click and hold the Security app icon on your desktop for quick access to features.
- βοΈ In the memory accelerator settings, you can set exceptions for important applications, such as instant messengers.
- π Regular use of the built-in accelerator helps maintain a stable level of free memory.
Users often wonder if you should keep your memory empty all the time? The answer lies in the algorithms of MIUI. The system itself can unload old applications when you don't have enough resources. Manual cleaning is only necessary when you notice obvious brakes or before you start a heavy game.

Use the Acceleration widget on your desktop to clean up memory in one tap without going into the application settings.
Expanding RAM: How it works
In modern Xiaomi smartphones, the feature βMemory Extensionβ has been introduced, which allows you to reserve part of the built-in storage (ROM) for the needs of RAM, especially for budget models with 4 or 6 GB of RAM, where every megabyte counts.
The technology works like virtual memory in computers, transfers rarely used data from fast RAM to a slower but bulkier drive, and activates this function in the Settings β Expand memory menu, and you will need to restart the device after changing the settings.
| Model of the device | Available for expansion | Recommended level | Impact on speed |
|---|---|---|---|
| Redmi Note 12 | up to +4GB | +2GB | Average. |
| Xiaomi 13 | up to +6GB | No expansion | High. |
| Poco X5 | up to +4GB | +4GB | Notable. |
| Redmi 12C | up to +2GB | +2GB | Critical. |
Itβs worth considering that using a drive as RAM has its nuances. The read and write speed of Flash memory is lower than that of a full-fledged LPDDR. So the performance gains will be noticeable in multitasking (when there are many tabs open), but not in heavy games.
Settings in the menu "For developers"
For advanced users, the HyperOS shell and older versions of MIUI provide access to a hidden developer menu, where you can fine-tune the behavior of the system when working with memory, and to get there, you need to click on the build number several times in the About Phone section.
One of the most useful features is the Background Process Limit, which is the default system that decides how many applications to keep in the background, and you can tightly limit that number, for example, setting a "No More than 2 Processes" value will force the system aggressively to unload the extra, freeing up resources for the active application.
Also worth noting is the "Do Not Activity" option, which, if you turn it on, will destroy the app as soon as the user leaves the screen, a radical method that is guaranteed to free up memory but can disrupt navigation or music players.
- π Find Process Statistics to analyze what is eating up resources right now.
- π The βComplete All Processesβ option on the developer menu runs deeper than the standard cleanup.
- π Disabling animations of windows and transitions will visually speed up the interface, reducing the load on the interface. GPU and RAM.
β οΈ Note: Do not change the settings associated with debugging USB or the choice of a mocap device, if you do not understand their purpose - this can lead to unstable operation of the system.
Managing application autoloading
Many applications tend to run with the operating system to receive notifications or update content, which leads to the fact that immediately after turning on the smartphone, a significant portion of the RAM is already occupied, and this process can be controlled through special permissions.
In newer firmware versions, the startup management is often hidden in the app settings or security section. You need to find an application you don't need in the background and prevent it from Autorun. It's also recommended that you disable the display on top of other applications for services that don't need it.
βοΈ Optimizing autoloading
Special attention should be paid to social networks and games. They often hang in the background, consuming resources even when you are not using them. In the Apps β Permissions β Autorun, leave only messengers on, from which you need instant notifications.

Memory consumption analysis through ADB
If standard methods don't work, you can use the Android Debug Bridge (ADB) debugging tool to access system statistics that are not available through a normal interface, and you need to connect your smartphone to your computer.
Using the adb shell dumpsys meminfo command, you can get a detailed report of which application takes up how much bytes. Unlike the task manager, this report shows real-world usage, including native libraries and graphic buffers.
adb shell dumpsys meminfo | grep -E "Total|Native|Dalvik"Using this data, you can identify the culprits of memory leaks, often one particular application that doesn't work properly, its removal or reinstallation can solve the problem globally, and through ADB you can force a process that doesn't close with conventional methods.
Clean installation and resetting of settings
When software optimization methods are exhausted and the phone continues to slow down, the radical but effective method remains: a complete reset, and a factory reset completely clears the RAM of program errors and βjunkβ accumulated over the years of use.
Before starting the procedure, be sure to back up your data in the cloud or on your computer. The process will take time, but will return the device to its original speed. Once reset, the system will use the memory as efficiently as possible, since all background processes will be deleted.
It's important not to install all the applications immediately after you reset, but to try working with a clean system for a couple of days, and to help you figure out if you have enough of the basic set of features, or what applications you really need, and to prevent the memory from clogging again.
