Owners of Xiaomi smartphones often face a situation where the device starts to work slower, applications open longer than usual, and the interface slows down. RAM (RAM) is a critical resource, on the filling of which the performance of the MIUI or HyperOS system depends directly on. When free space in RAM runs out, the processor is forced to constantly unload and download data, which causes noticeable delays in the work of the gadget.
Understanding which processes consume resources allows not only to clean the phone, but also to optimize its performance for the long term. Unlike desktop operating systems, Android mobile platforms have their own specifics of memory management, where background processes can be aggressive. Xiaomi provides users with several built-in tools, and also supports third-party solutions for deep analysis.
In this article, we will look at all the monitoring tools available, from simple built-in widgets to advanced engineering menus, and learn how to distinguish between system and user processes, and understand when to interfere with the system and when it will only harm stability.
Use of built-in MIUI and HyperOS tools
The easiest and most affordable way to know what's happening to your smartphone's memory is to use regular optimization tools, and the MIUI shell and the new HyperOS already have a Security app pre-installed, which takes over the task manager, which shows the overall load and allows you to quickly free up resources at a single click.
To see the details, you need to go to the memory settings inside this application, which displays a list of processes sorted by space, but it's worth remembering that a standard manager often hides system services by focusing only on user applications.
- 📱 Click and hold the Security app icon on your desktop.
- 🔍 Select “Memory Cleanup” or launch the application and go to the “Memory” tab».
- 📊 Learn the download schedule and list of running processes.

For more accurate real-time monitoring, enable the display of a floating memory window in the developer settings, which will be discussed below.
Importantly, the automatic cleaning that these tools offer is not always effective. Android is designed to keep frequently used applications in memory for quick launch. Forced shutting down all processes can lead to increased battery consumption, as the system will have to re-initialize services the next time it accesses them.
Monitoring through the “Developers” menu
For users who need a professional level of control, there is a hidden menu called "Developers" that contains debugging tools that allow you to see how the system works in real time, and to activate this mode, you need to quickly click seven times on the build number in the "About Phone" section.
Once activated, a new item will appear in the settings menu, and inside it we're interested in the memory section, and you can find RAM usage statistics that update dynamically, and you can track how resource consumption changes when you start heavy games or cameras.
☑️ Activation of the developer mode
This section also includes Process Statistics, which shows the detailed memory consumption of each service that is running, and not only the main apps, but also Google background services, system demons, and synchronization processes, which is an invaluable tool for finding memory eaters.
⚠️ Warning: Do not disable system processes with unknown names in the developer menu.This can lead to unstable interface operation, loss of communication or cyclical restart of the device.
Third-party applications for memory analysis
If built-in tools are not enough, Google Play comes to the rescue, with programs like Simple System Monitor, DevCheck, or CPU-Z providing comprehensive information about the state of the hardware, graphing, load history, and overflow notifications.
The thing about these apps is that they can display information as a widget on the desktop, so you can control things without going into the settings, and some even have a "reinforced cleaning" feature that is more aggressive than the standard one, so you can forcefully close the background tasks.
| Annex | Type of display | Additional functions | Impact on the battery |
|---|---|---|---|
| Simple System Monitor | Graphics, widgets | Monitoring of CPU, GPU | Low. |
| CPU-Z | Tables, text | Info on sensors, battery | Minimum |
| Greenify | Lists of processes | Application hybridization | Average. |
Using third-party software requires careful attention to permissions. Programs often require advanced ADB or root permissions to analyze memory in depth, and without them, they can only show general information that is available to regular applications.
Analysis through Engineering Menu and ADB
For advanced users and professionals, there is a way to get data through a computer using the ADB debugging bridge (Android Debug Bridge), which allows you to download the full log of memory usage in a text format that can be analyzed on a PC.
To do this, you need to connect your smartphone to your computer, enable debugging over USB, and enter a command in the terminal, and the resulting report will contain details for each byte used in the system, including cached data and memory.
adb shell dumpsys meminfoThis command will produce a huge list of processes, and to filter out only the most difficult ones, you can use additional sorting parameters, which is indispensable when you need to understand why the phone brakes immediately after turning on, when the user has not yet launched any applications.
What is shared memory?
Why memory is filled and how to fix it
The constant lack of free RAM on Xiaomi is often caused not by one cause, but by a combination of factors: modern applications are becoming more demanding, and Android algorithms assume active data caching to speed up work.
One of the main reasons is heavy social networks and messengers that don’t have strict optimization, they can consume hundreds of megabytes even in the background, and the number of widgets on the desktop and live wallpaper that are constantly updated also influences.
- 🚀 AutoRun: Many applications start with the system, taking up space.
- 🔄 Background Activity: Apps Continue to Work After Closing.
- 📦 Cache size: Accumulated temporary files take up resources.
To solve the problem, it is recommended to check autorun settings regularly, and there is a corresponding section in the Security menu where you can prevent unnecessary programs from starting on their own, which will significantly reduce the initial load on the system after turning on the phone.
⚠️ Warning: Do not use accelerators and cliners of dubious quality. They often consume a lot of resources and show intrusive advertising, claiming to clear memory, although the effect of them is minimal.
Advanced system settings and optimization
Owners of Xiaomi smartphones with a small amount of RAM (4 GB or less) can use the memory expansion feature, which allows you to reserve some of the internal flash memory for the needs of RAM, although the speed of such memory is lower, it helps the system not to close applications when resources are scarce.
You can turn this on in the main settings of the system, in the section "Additional" or "Expand memory." Once activated, the phone will restart, and the amount of RAM available will increase, but it is worth considering that active use of this feature can slightly reduce the life of the drive due to intensive data recording.
Also, you should pay attention to visual effects: disabling animations in the developer menu (the parameters of the animation scale) will not only speed up the visual response, but also reduce the load on the GPU and memory during transitions between screens.
💡
Optimal system operation is achieved by balancing the number of active applications and available resources; full memory filling is normal for Android, critical only the lack of free space for new tasks.
