Owners of Xiaomi, Redmi and POCO smartphones often face the need to make the most of their device in heavy mobile projects. Android standard settings are sometimes not enough to work consistently in demanding games like Genshin Impact or PUBG Mobile. MIUI and the new HyperOS have powerful built-in tools that can be hidden or disabled by default.
Many users are unaware that their device is much faster and more stable, and the problem is not weak hardware, but aggressive energy savings and lack of proper game mode configuration, and in this guide, we will discuss how to activate hidden functions, disable unnecessary restrictions and make the processor work at full power.
The right setup not only allows you to raise the number of frames per second, but also reduce the heating of the case during long sessions. We will consider both standard optimization tools and advanced methods for advanced users who are willing to experiment with the parameters of the system.
Activation and Configuring of Game Turbo
The main tool for gamers in the Xiaomi ecosystem is the Game Turbo app (formerly known as Game Center), which is not just a launcher, but a comprehensive CPU and RAM resource management system. By default, it can be inactive or work in a gentle mode. To access full functionality, you need to add the game to the application list through the built-in security menu.
Go to the Security app on your smartphone and find the Game Turbo icon. If it's not on the home screen, search inside the tool folder. In the menu that opens, click on the settings icon (cogs) or the plus to add apps. This is where the prioritization happens, and the system will know that the running application needs to give all the power available.
⚠️ Warning: Enabling Acceleration mode in the Game Turbo can result in faster battery discharge and increased body heat. Use this mode only when the device is connected to a charge or when every frame is important.
Inside the Game Turbo settings, you'll find the Game Acceleration slider, which redistributes CPU and GPU resources to the active application, limiting background processes, and also has a Sound Amplifier that makes the steps and shots in shooters clearer and louder, giving you a tactical advantage.
- 🎮 Add all heavy games to the Game Turbo list for automatic optimization.
- ⚡ Activate the “Acceleration” slider for maximum process priority.
- 🔊 Enable the sound equalizer to improve positioning in shooters.
- 🚫 Turn off notifications and calls while playing through the "Do Not Disturb" profile".
Remember that you can create customized profiles for different games, for example, for shooters, sensor response speed is important, and for strategies, FPS stability. Set these parameters separately for each application, so that the system does not waste resources where it is not necessary.
Hidden developer settings for gamers
To get a deeper setup, you need to access the Developer Menu, which is hidden from the eyes of the average user to prevent critical settings from accidentally changing, and to activate it, you need to quickly click seven times on the build number in the About Phone section, and after the "You're a developer" message appears, a new item will appear in the settings menu.
In the developer section, we are interested in the block associated with graphics rendering. GPU (Preferred GPU Here you can force the system to use a system driver or a game driver, which sometimes solves problems with textures and departures.
Changing the scale of animation doesn't add FPS to games directly, but it does make the interface lightning fast, which subjectively speeds up the device. Set 0.5x or Disabled for all three animation points. This will free up the CPU cycles that used to be spent on rendering transitions between windows.
Should we include the Forced 4x MSAA?
Another important parameter is the Background Process Limit: Set a limit of "No More than 2 Processes" or "No Background Processes" before starting the game, this is guaranteed to close all unnecessary applications that can consume RAM. After the game, remember to return the standard value to ensure that messengers and music work correctly.
- 📉 Reduce the scale of animation windows and transitions to 0.5x.
- 🔄 Change the driver. GPU Systemic if the game is not running smoothly.
- 🧹 Limit background processes to free up RAM.
- 🚫 Turn it off. HW-overlay (on some models, this removes the interface lags).
Be careful with settings you don't understand. A random change in encoder settings or memory limits can lead to unstable system operation. The critical parameter is "hardware acceleration of rendering" - disabling it will completely break the graphical interface.
Memory and background management
Effective memory management (RAM) is key to smooth gaming. The MIUI and HyperOS shells have an aggressive memory cleanup system that you can configure. Go to Settings → Advanced Settings → Expand memory. You can add virtual memory to storage, but games are more important than physical RAM.
There is a myth that constantly cleaning up memory through Close All is useful.In fact, Android needs free space to caching frequently used data. However, before starting a heavy game, manually cleaning through the built-in speed booster in the notification curtain really helps to reset the accumulated junk and running services.
There's a memory cleaner feature in the Security app that goes deeper than standard, and using it regularly before a game session frees up to 1-2 GB of RAM, and it's worth checking the app boot list and disabling anything that isn't vital.
| Parameter | Recommended value | Impact on play |
|---|---|---|
| Scale of animation | 0.5x or Retraction. | Accelerates system response |
| Background processes | Maximum 2 | Frees RAM. |
| Window animation | 0.5x | Subjective acceleration |
| GPU Driver | Systems/Game | FPS stability |
If you have a model with Memory Extension, try temporarily disabling it to check performance. In some scenarios, using fast physical memory works better than mixing slower flash memory, which reduces micro-lags when loading textures.
☑️ Checklist before the game launch
Optimization of the display and refresh rates
Image quality and smoothness are directly dependent on the screen settings. In the Settings menu → Screen make sure the refresh rate is set to the maximum value (90 Hz, 120 Hz or 144 Hz depending on the model). Auto mode can mistakenly reduce the hertz in games to save energy, so it is better to lock in the maximum.
Also worth paying attention to is the screen resolution. In the screen resolution section, select High for the best picture. However, if the game is going with FPS drawdowns, switching to Standard can give performance gains of up to 15-20%, as the processor will have to render fewer pixels.
Dark Mode is not only aesthetics, it's also a way to reduce the load on some types of matrices and reduce the heat a little. In Game Turbo settings, you can force a dark theme to be included for specific games, as long as they support the system design.
⚠️ Attention: Constant screen operation at maximum brightness and frequency of 120 Hz significantly increases power consumption. For long gaming sessions without charging, it is better to reduce the frequency to 60 Hz or 90 Hz.
The DC Dimming feature (if available in your region via a hidden menu) reduces screen flickering at low brightness, which reduces eye fatigue, and can be activated via the Services and Feedback app in the Top Features section by entering the code ##6484## (code may vary on different versions of MIUI).
Thermal and energy control
Trottling (reduced processor frequency due to heat) is the main enemy of high FPS. MIUI has built-in temperature limits. You can use third-party cooler applications (external fans) or software methods to circumvent or mitigate these.
In the battery settings (Settings → Battery), select Speed mode. Standard Balanced mode can artificially limit the CPU frequency even if the phone is not hot. Speed mode allows the CPU to run at peak frequencies longer.
Remove the case during the game, if it is dense and does not allow air. The heat should be effectively removed from the body. If you play at home, you can put the phone on a cold surface (stone, metal), but not on soft tissues that work as a thermal insulator.
💡
Use external coolers for smartphones, which cool the CPU area to 10-15 degrees, preventing trottling and maintaining a stable FPS throughout the hours of play.
There is a method of disabling the system thermosensor through ADB-It's extremely dangerous and can cause the device to fail due to overheating. `rm /system/etc/thermal-engine.conf` risk-awareness.
Additional tips for advanced users
For those who are not afraid of difficulties, there is a method of cleaning the cache. DNS. Go to Settings. → Connection and sharing → Private DNS. Select "Host Name of the Provider" DNS" and enter the address dns.google or 1dot1dot1dot1.cloudflare-dns.com. This can reduce ping in online gaming and speed up resource loading.
Also, you should turn off Google and Mi Cloud sync while you play. Background uploading of photos and contacts creates network traffic and a load on the processor. Temporarily disable the Wi-Fi assistant, which can switch the network in search of a better signal, causing lags.
Regularly update the gaming services of Google Play Games and the applications themselves through the GetApps store or Google Play. Developers often release patches that optimize the game for specific models of Snapdragon or MediaTek processors.
💡
A comprehensive approach is key to success, and the combination of Speed mode, Game Turbo activation and memory cleanup is better than using just one method.
Remember that no software setup will make a budget smartphone a flagship, but the right configuration allows you to unlock 100% of the potential of your Xiaomi, ensuring the maximum possible comfort in games.
