Modern Xiaomi, Redmi and POCO smartphones have powerful hardware that is not always used at full capacity in standard mode. MIUI or its new version of HyperOS are set to balance energy efficiency and performance by default, which can limit the potential of the processor in demanding games. Users often face frame drops or micro-freezes, unaware that activation of special profiles can make a difference.
Turning on the performance mode is not just a set of "maximum brightness", but a comprehensive reconfiguration of the algorithms of the processor and the graphics accelerator. In this article, we will discuss the standard optimization tools, hidden engineering menus and third-party methods that allow you to squeeze the maximum out of your device. It is important to understand that aggressive tuning can affect the heating of the case, so the process should be approached consciously.
Before you start deep tuning, you need to determine the current state of the system and the availability of updates. Often manufacturers release patches that improve the stability of the GPU, so ignoring software updates can negate all optimization efforts. Next, we will look at the step-by-step algorithm for different versions of the shells.
Activation of Game Turbo and Game Profiles
The most affordable and safest way to improve performance is to use the built-in Game Turbo tool (formerly known as Game Center), which does not just run games, but redistributes system resources, prioritizing gameplay over background tasks, and accessing it is enough to open the Security app and find the corresponding section in the bottom menu or on the main screen of the toolbox.
Once you add games to the list, you get access to the sidebar during gameplay, and you can activate the Performance profile, which enforces a high CPU frequency, preventing trottling in the early stages, but you have to consider that running at the limit of your ability leads to faster battery discharge.
- 🚀 Open the Security app and go to the Game Turbo section.
- 🎮 Add the right games through the button «+» control menu.
- ⚙️ In Game Turbo settings, select the “Performance” or “No Limitations” profile».
- 📉 Turn off notifications and calls to prevent interruption of the process.
Importantly, some global firmware versions of Game Turbo may be stripped of functionality compared to Chinese versions, and users often resort to installing China in their phone settings to unlock the full feature set, although this may affect some local services.
⚠️ Attention: Maximum performance mode in games weighing more 3-4 GB on passive cooling devices can lead to critical heating of the housing above 45 degrees Celsius.
Engineering menu and hidden processor settings
For more advanced users, you can access hidden system settings through an engineering menu, and it's a powerful tool to manage parameters. CPU and GPU The menu is accessed through a set of special code in the "bell ringer" or through the ADB-The functionality depends on the specific model of the processor (Snapdragon, MediaTek, Exynos).
One of the key features here is power scenario management, so you can prevent the system from reducing the CPU frequency when it reaches a certain temperature, which allows you to keep the FPS high for a longer time, but requires external cooling, such as a smartphone cooler.
Risks of using the engineering menu
The code ##6484## or #3646633## is often used to log in, but newer versions of MIUI 14 and HyperOS often deny access to these codes, requiring special activator applications or USB debugging from a computer.
- 🔍 Enter the code of the engineering menu in the phone application.
- 🛠 Go to the Hardware Testing or Common section.
- 🔋 Find a Power subsection or CPU Control.
- 📈 Change your profile from Balanced to Perfection».
Customization of animations and graphics in the developer menu
The developer menu is a standard Android section that is often ignored by ordinary users, although it contains important parameters for the visual responsiveness of the system. To activate it, you need to quickly click seven times on the build number in the About Phone section. Once the corresponding notification appears, the menu will become available in the main settings.
So here we're interested in zooming animations. The standard value is 1x, but changing it to 0.5x or shutting it down completely creates the illusion of faster interface performance. Although this doesn't add processing power to the processor, the subjective feeling of "performance mode" is enhanced as the system responds more quickly to touch.
| Parameter | Standard value | Optimal for speed | Impact |
|---|---|---|---|
| Window animation | 1x | 0.5x | Application folding speed |
| Animation of transitions | 1x | 0.5x | Switching speed between screens |
| Duration of animation | 1x | Out. | Total response rate of UI |
| Background processes | Standard | No more than 4. | Freeing RAM |
💡
If you use a smartphone for gaming, the developer menu should also include the option “Disable display on top of other apps” for background programs that may consume resources.
Also in this section, you should pay attention to the item “4x MSAA” (aliasing), its inclusion improves the quality of graphics in games that support OpenGL ES 2.0, but can significantly load the GPU and reduce the total number of frames per second.
Optimization of memory and background processes
Performance in games is directly dependent on the amount of free RAM (RAM). MIUI aggressively manages memory, but sometimes background processes can eat up valuable megabytes. Before starting a heavy game, it is recommended to use a built-in memory cleaner or the function "Memory Extension" if it is available on your model.
The memory expansion feature uses a portion of the internal drive (ROM) as virtual RAM. While this allows more applications to be kept open, the virtual memory speed is much lower than the physical. Speed is critical for games, so paradoxically, disabling the memory expansion can give performance gains on devices with a fast UFS type of memory 3.1 and higher.
- 💾 Go to Settings. → Additionally. → Expansion of memory.
- ❌ Try disabling the function and restarting the device.
- 🧹 Close all unused applications before playing.
- 🗑 Clear the cache of system services through the storage menu.
Another important aspect is the startup management. Many applications run with the system and hang in the background, consuming CPU time. Go through the boot list in the application settings and leave only the messengers and system services necessary for the phone to work.
Temperature control and trottling
The main enemy of the performance mode is heat. When the CPU temperature reaches a critical point (usually about 80-85 ° C for the core), the protective mechanism is triggered - trottling. The processor forcibly reduces its frequencies to cool down, which leads to a sharp drop in the FPS and the appearance of jerks in the game.
To avoid this, it is necessary to ensure effective heat removal. The use of covers while playing heavy projects is highly discouraged, as they act as a thermal insulator. It is best to play without a cover or use special cases with an open rear panel and built-in fans.
⚠️ Warning: Never place a high-load smartphone on soft surfaces (sofa, bed, blanket) that block heat escape routes and can cause the battery to overheat and degrade.
☑️ Controlling temperature during play
There are monitor apps that show the current temperature of the processor in real time, and if you see that the temperature rises rapidly in the first 5-10 minutes of the game, then the standard cooling system is not enough, and software methods for turning on the "performance mode" will not help without external cooling.
Third-party utilities and the risks of using them
There are many apps on the Google Play store that promise to “accelerate games” and “unlock hidden modes,” most of which (All-In-One Toolbox, Clean Master and similar) work on the principle of cleaning RAM, as does the MIUI system itself. The real benefit can only be provided by specialized launchers or tools for changing the frequencies of the processor that require Root rights.
Obtaining superuser rights (Root) opens up access to the kernel files of the system, allowing you to edit the configuration files of the processor. However, this action cancels the warranty on the device and carries high risks. A mistake in one character when editing the system file can turn a smartphone into a brick.
If you do decide to make a deep modification, make sure to make a full backup of the data, and it is also worth considering that banking applications and some games with cheating protection may stop working on rooted devices.
💡
The most effective and safest way to improve performance is to combine Game Turbo, turn off background processes and ensure the device is physically cooled well.
