Every Xiaomi smartphone owner sooner or later faces slowdowns, long-running applications or sudden program crashes. Often the culprit of these problems is overcrowded RAM (RAM), which does not have time to cope with the flow of tasks, running background processes and heavy graphic elements of the MIUI or HyperOS shell. The system begins to work slower, as the processor has to constantly redistribute resources to ensure smooth current action.
Optimizing system memory is not just cache cleaning, but a comprehensive process of managing device resources to free up the amount of RAM used for active applications. In Xiaomi devices, special algorithms built into the shell are responsible for this, which automatically complete inactive processes, but often require user intervention to achieve maximum performance. Understanding the principles of RAM will help you extend the life of the gadget without having to replace it.
In this article, we will take a closer look at how memory works in Redmi and POCO smartphones, look at the built-in acceleration tools, and figure out which settings really work and which are myths. You will learn how to set up the system correctly so that your phone will fly even after a year of active use. Proper resource management is the key to the stable operation of any mobile operating system.
Principles of RAM in the shell of MIUI and HyperOS
Xiaomi’s RAM in smartphones works on principles similar to computer systems, but has its own peculiarities due to the architecture of Android and deep customization of the shell. When you open an application, its data is loaded into RAM for quick access. Unlike older systems, Android does not seek to immediately unload the application from memory when it folds, but leaves it in a “frozen” state for quick return.
But MIUI is known for its aggressive energy-saving policies, which often conflict with the user's desire to keep many applications open. The system can force the process to be completed even if you've recently used it, which causes the application to be re-entered rather than re-restored, which consumes more time and battery life.
With the release of the new HyperOS shell, the company has tried to redesign the task manager mechanism to make it more intelligent. Now the system better analyzes user behavior patterns and stores exactly the applications that you need most. However, the physical volume of RAM remains a limiting factor that can not be circumvented by software methods without losing performance.
⚠️ Attention: Do not aim to ensure that the memory occupancy chart always shows free space. Empty RAM in Android is wasted memory, since the system uses it to caching frequently used data to speed up work.
It's important to understand processes by distinguishing between memory types: Internal storage (ROM) is responsible for storing files, and RAM is responsible for the time data of running programs, and you can't confuse them, because optimization methods for them are radically different.
Built-in cleaning and acceleration tools
Each Xiaomi smartphone has a Security system app preinstalled, which includes memory cleanup functionality, the first and basic tool that any user should have in their arsenal, and allows them to complete background processes and free up RAM in one click.
When you click on the Cleanup button, the system analyzes the running applications and closes the ones that are not on the exception list, but it is worth noting that this method has a temporary effect. Android will immediately start reopening the necessary system services, and in a few minutes the memory will be again filled by 60-70%, which is normal behavior.
A more effective tool is memory extension, which allows you to reserve a portion of internal storage (ROM) and use it as virtual RAM, and while the storage read speed is lower than that of real RAM, it helps keep more applications in the background.
- 🚀 Expanding Memory: Virtual Volume Increase RAM internal storage.
- 🧹 Deep Cleanup: Delete temporary files and cache taking up storage space.
- 🛡️ Game Booster: Special Mode Prioritizing Resources for a Launched Game.
- ⚙️ AutoRun: Managing applications that start with the system.
Using a built-in game booster is also a form of optimization: When you run a game through this mode, the system blocks notifications, limits the background activity of other applications, and prioritizes the gameplay process to the highest level, preventing friezes and lags.
Setup of autoload and background activity
One of the main reasons for memory bloating is the sheer number of apps that have been signed into autoboot, and even if you're not using social media or stores right now, they can run in the background, consuming resources and sending requests to the server, and controlling autoruns is a critical step in optimization.
To manage this setting, you need to go to the Security settings and find the Permissions or Autostart section, and here you will see the full list of programs that start with the phone, and it is recommended that you leave only messengers (for notifications) and system services on.
☑️ Checklist of auto-start settings
In addition to auto-run, you should pay attention to background activity, so in the battery settings, you can limit background activity for applications that do not require constant connection, which will not only free up memory, but also significantly extend battery life.
There is also a hidden feature in the developer menu to limit the number of background processes, but it should be used with caution, as too stringent restrictions can lead to malfunctioning applications and data loss.
Memory Extension: Memory Extension Technology
Memory Extension technology has become the standard for modern Xiaomi, Redmi and POCO smartphones, which allows you to add 2 to 7 GB of virtual memory depending on the device model.
You can activate this feature in the “Additional” menu in the main system settings. Once turned on, the phone will suggest a reboot. Importantly, this feature is most effective on devices with a small amount of physical RAM (4-6 GB). On flagships with 12 GB and more RAM, the performance gains may not be noticeable.
| Physical RAM Volume | Recommended expansion | Impact on speed | Effect on storage wear |
|---|---|---|---|
| 4GB | +2/+3GB | High (reduces departures) | Minimum |
| 6GB | +2GB | Average. | Low. |
| 8GB | +2GB | Low. | Low. |
| 12 GB or more | Not required | Absent. | Absent. |
⚠️ Warning: Constantly writing and reading data in memory expansion mode theoretically increases the wear and tear of the internal drive. If you have enough physical memory (8 GB or more), it is better to disable this feature to save disk life.
Consider that virtual memory is still slower than real RAM, so don’t expect miracles: heavy games won’t go 20 FPS more, but multitasking in ordinary tasks will improve.
Developer Options for Advanced Users
For those who want to take full control of the system, there is a Developer Menu, which you can access by quickly clicking on the build number in the About Phone section several times, and there are powerful memory and animation management tools hidden here.
One useful feature is to limit background processes, so you can set a limit, like "No more than 4 processes," which severely limits the system's appetites, but can cause music to stop playing in the background or file downloads to be interrupted when the screen is rolled up.
How to turn on the developer menu?
And you can also find the "Do Not Save Action" setting on this menu, and if you activate it, the system will destroy the activity of the application as soon as the user leaves the screen, which is a radical method that completely frees up memory, but does not allow the user to use the system to do so.-multitasking impossible.
Another important parameter is animation scale: Reducing window, transition and animation duration from 1x to 0.5x visually makes the interface more responsive, and while it doesn't free up bytes of memory, it reduces the load on the GPU and creates a sense of speed.
- 🎨 The scale of animation: Reduced to 0.5x Accelerates visual response.
- 🔒 Background Processes: Limiting the Number of Active Tasks.
- 🚫 Do not save actions: Complete cleaning of activity when exiting.
- 📉 Adaptive brightness: Affects energy consumption and heating.
Third-party applications: benefit or harm?
There are thousands of software-cliner apps in the Google Play marketplace that promise to “speed up the phone in one click.” But in modern Android versions, these programs often do more harm than good, consume resources, display ads and create the illusion of working simply by restarting processes that the system will immediately rediscover.
The built-in memory management mechanism in MIUI and HyperOS is more efficient than any third-party counterpart. The system knows which processes are important and which can be completed. A third-party cliner, by forcibly closing system services, can cause instability or increased battery consumption for their re-start.
⚠️ Warning: Avoid installing apps that promise “processor cooling” or “magic acceleration” and often simply display banner ads and collect user data without performing the stated functions.
The only exception is specialized analysis tools like DevCheck or CPU-Z, which allow real-time memory monitoring but do not interfere with the system.
💡
Tip: Instead of installing heavy climbers, set up automatic cleaning in the standard Safety app. Go to the cleaner settings and turn on the Notify of garbage option so that the system itself offers cleaning when it reaches the threshold.
Thus, the best optimization is the absence of unnecessary interference with the work of system processes and competent management of installed applications, regular software updates and removal of unnecessary programs give a greater effect than any accelerators.
