Xiaomi and Redmi smartphone owners often face a situation where the device starts to run slower, applications open with a delay, and the system hangs down. The main reason for this behavior is often overcrowded RAM. Unlike the built-in storage where you put photos and music, RAM is responsible for running programs right now.
When free resources become critically scarce, the MIUI or HyperOS operating system is forced to force the background processes to close, which leads to application reboots and data loss. Understanding how to properly manage the clipboard and process cache in real time is key to stable operation of the gadget.
In this article, we will analyze not only standard cleaning methods, but also hidden system capabilities that will help significantly unload the device without installing third-party software.
Understanding the work of RAM in the shell of MIUI and HyperOS
The Android operating system installed on Xiaomi Redmi uses memory on the principle of “the more busy, the better the system works.” However, aggressive optimization of the MIUI shell sometimes leads to useful applications being unloaded too early, the user needs to clearly distinguish between embedded memory (ROM) and RAM (RAM).
If the first one is filled with user files and can be cleaned by removing the unnecessary, the second one requires constant monitoring of running services. Many users mistakenly believe that constant full cleaning of RAM is useful, but this causes the processor to waste energy on restarting system processes.
The optimal strategy is to selectively free resources from “heavy” applications, such as navigators or games, that have not been closed properly.
- 📱 Background processes – services that operate in hidden mode to update notifications.
- 🚀 Application cache – temporary files that speed up the launch of programs, but take up space.
- ⚙️ System services are shell components that cannot be completely turned off without losing functionality.
It is important to understand that modern versions of Android effectively manage resource allocation, but manual intervention is necessary when there are clear signs of power shortages.
Standard cleaning methods through the smartphone interface
The easiest and safest way to free up resources is to use the system's built-in tools, and the MIUI shell features a special quick-cleaning mechanism that can be accessed directly from the desktop or lock screen.
To perform the procedure, you need to find the Security widget or the corresponding icon in the menu. Once the scan is started, the system will prompt you to delete temporary files and close the background applications, which instantly increases the amount of free memory available.
Also effective is the method of closing applications through the multitasking menu, which allows you to force the work of heavy programs that you are not currently using.
☑️ Checklist for quick cleaning
Regularly doing these simple actions helps keep the system in good shape without the need for deep tuning intervention.
Using the "Security" application for deep cleaning
Each Xiaomi Redmi smartphone has a Security system app, which is the central node for performance management, which provides deeper cleanup access than the standard task closure menu.
When you go to Cleanup, you can see not only the amount of space you're taking up, but also the details of the applications. The Acceleration function inside this app analyzes the processes that are running and suggests that you close the ones that consume the most resources.
⚠️ Note: When using Deep Clean, carefully watch which files are deleted. System logs and card cache may take up a lot of space, but deleting them will lead to longer loading of cards on the next run.
In addition, in the settings of the application "Security" you can activate automatic cleaning when you reach a certain filling threshold, which eliminates the need to do it manually.
- 🧹 Cleaning up garbage – removing residual files from remote applications.
- 🔋 Battery optimization – often involves closing energy-intensive processes in RAM.
- 🛡️ Antivirus – checking for malware that can covertly mine or collect data, loading memory.
The use of native tools is preferable to installing cleaners from the Play Market, since they have higher access rights to the system.
Configure extended memory and virtual swap
Newer models of Redmi and Xiaomi support RAM expansion technology with space in the internal storage. This feature, often called Memory Extension or Virtual Memory, allows the system to use part of the permanent disk as additional RAM.
You can activate this option in the Settings menu → Advanced Settings → Expand memory. The system will prompt you to select the volume that will be reserved for these needs, after which you will need to restart the device.
