Smartphone owners from the Chinese giant often encounter the term “acceleration” when it comes to performance tuning. Xiaomi’s acceleration is not one magic button, but a set of software algorithms aimed at cleaning RAM and reallocating CPU resources for running applications. In the interface of the MIUI shell or HyperOS, this feature is often hidden behind the “Security” icon or integrated into game modes.
Users are looking for answers to the question of what kind of mechanism it is and whether it really helps when the system starts to slow down. Modern devices have enough power, but the abundance of background processes can reduce performance at critical moments. Understanding the principles of operation of the optimizer allows you to manually control the power consumption and response rate of the interface, which is especially important for models of the mid-range segment.
In this article, we will discuss in detail how the built-in accelerator works, how it differs from the game mode and whether you should trust third-party applications from the Play Market. You will learn how to properly configure Settings → About the phone → MIUI version to access hidden developer features that directly affect the speed of the system. Xiaomi provides powerful tools that you need to be able to use.
The principle of operation of the standard memory accelerator
The regular cleaning mechanism, available through the Security app, works on the principle of forced completion of background processes. When you press the "Clean" or "Accelerate" button, the system analyzes the list of services that have been launched and closes those that are not high priority. This frees up RAM (RAM), allowing the active application to use more resources.
But the difference between real-world optimization and visuals is that running broom animation or a filling circle is designed to make the user feel in control of the device. In reality, Android itself is a great memory controller, and frequent forced cleaning can even be harmful, forcing the processor to reopen closed applications, which consumes the battery.
⚠️ Continuous manual memory cleaning through the standard accelerator every time 5-10 minutes can lead to increased battery consumption, as the system will constantly restart system services.
However, in situations where one application has eaten all memory and the phone has stopped responding to touch, using a regular boost is a justified step. MIUI tries to keep important messengers and system processes, closing primarily "heavy" but inactive programs.
Game Turbo: Game Acceleration and Its Functions
The Game Turbo feature, which is the most effective acceleration tool for gamers, is not just an overlay with settings, but a full-fledged performance profile that redistributes CPU frequencies and network packet priorities in favor of running a game, and when activated, the system limits the background activity of other applications.
Inside the game acceleration menu, users can find graphics settings that are not available in all default games, which can increase frame rate (FPS) or improve touchscreen response. For devices with Snapdragon and MediaTek processors, this allows you to squeeze extra frames per second, making gameplay more smooth.
☑️ Setting up the Game Turbo
And it's important to note that the maximum performance settings in the Game Turbo are going to heat the case, and if the device gets overheated, the trottling goes off, and the frequencies are artificially low, which is going to backfire, lag, so the balance between graphics quality and temperature is key.
| Function | Description | Impact on the battery |
|---|---|---|
| Cleaning up memory | Closing of background processes | Low. |
| Game Turbo | Priority of CPU/GPU for the game | High. |
| Expansion of memory | Using storage as RAM | Average. |
| Network optimization | Priority of gaming packages | Average. |
Expanding RAM: Virtual RAM technology
Newer versions of HyperOS firmware and later MIUI have introduced RAM Extension, which allows you to use part of the embedded storage (ROM) as an additional virtual RAM, and on the menu this is displayed as "+2 GB", "+4 GB" or "+8 GB" to the main RAM.
The technology is that the system creates a paging file to reset data from rarely used applications, which prevents them from being uploaded from memory when resources are scarce, but the speed of the UFS or eMMC drive is still lower than that of real LPDDR4X or LPDDR5 RAM.
Should I include memory expansion?
You can activate this option in Settings → Advanced Settings → Expand memory. After turning on, you will need to restart the device. If you notice that the phone has become slower after turning on this feature, it should be turned off, since on fast drives overlays of the file system can create an extra load on the controller.
Hidden Developer Settings for Advanced Developers
For those who want to maximize interface speed, there are hidden developer menus that are accessed after you click seven times on the build number in the About Phone section, and these are the settings that affect the visual response rate of the system.
The most useful parameters are animation scale. By changing the values of "Scale of window animation," "Scale of transition animation," and "Duration of animation" from 1x to 0.5x, you visually speed up the interface. Windows will open instantly, creating a sense of high performance even on older models.
Also on this menu is the "Background Process Limit," which means that by setting a limit on the number of background processes, you force the system to clear memory faster, but beware: too aggressive settings can disrupt messengers that stop notifying in the background.
⚠️ Warning: Do not change the settings in the "Graphic accelerator" or "Simulation of additional displays" section unless you know exactly what they are responsible for.
Another important option is "Do Not Save Activities," which when you turn on this feature, the system will destroy the application as soon as you fold it, a radical acceleration method that guarantees free memory, but kills multitasking.
💡
Before you change the developer settings, take a screenshot of the original values, which will help you quickly return everything to the same way if the system starts to behave incorrectly.
The impact of background applications and services on speed
A common reason for speeding up is not a lack of resources, but rather a misuse of resources. Many of Xiaomi’s pre-installed apps and services (MSA, Mi Video, Mi Music) can run in the background, consuming traffic and CPU time. Disabling unnecessary services is the best way to speed up.
It is recommended to audit installed programs. Remove those that you do not use. For system applications that cannot be removed, you can use the adb shell pm disable-user --user 0 name.packet command via your computer to completely disable them without root rights.
- 📱 MSA (MIUI System Ads: Advertising service, which is significantly reduced by the load on the CPU and the Internet.
- 📊 Analytics: Use statistics collection services that can be safely disabled in privacy settings.
- ☁️ Cloud sync: Constant uploading of photos and files can slow down the system when the network signal is weak.
Controlling auto-run apps is another important aspect. The Security app has a section called Permissions → Auto-Run. Leave only what you really need to see in the background (like messengers or alarm clocks) on it, and the rest is better off preventing the phone from loading faster and running smoother.
Myths about acceleration and third-party applications
There are thousands of apps in the Play Market with names like "Clean Master," "Speed Booster" and other variations, and users often ask if they should be installed to speed up Xiaomi, and the answer is clear: in most cases, these apps are unnecessary and even harmful.
The MIUI shell already has built-in cleanup and optimization mechanisms that work at the core level of the system more efficiently than third-party add-ons. Third-party accelerators often simply duplicate the function of the regular cleaner, but at the same time consume resources, display advertising and collect user data.
The only exception is specialized tools to clean the cache of specific applications (for example, Telegram), but this can be done manually through Settings → Applications → Application Management. Using aggressive Task Killers on modern versions of Android can disrupt the system, as the OS perceives this as an attack and tries to restart dead processes, creating a cycle of endless load.
💡
The best acceleration for Xiaomi is cleaning the storage (free at least 15-20%), disabling MSA ads and competent auto-run management, rather than installing third-party boosters.
