Mobile gaming has long moved from the category of simple entertainment to a serious industry, where every frame decides the outcome of the battle. Xiaomi smartphone owners often face a situation where a powerful processor does not give the expected performance due to the software limitations of the MIUI or HyperOS system. Aggressive energy saving optimization and background processes can significantly reduce FPS (frames per second), causing unpleasant jerks and input delays.
In this article, we will discuss proven methods that will help you get the most out of your device. We will not offer the installation of dubious “boosters” that only consume battery power. Instead, we will adjust system parameters, activate the hidden potential of Game Turbo and correctly allocate the CPU resources for stable operation of heavy applications.
Before we get to the tricky ones, it's worth checking the basic settings that many people forget. Often the problem isn't the hardware, but the crowded cache or activated visuals that aren't needed during gameplay. Let's take all the steps sequentially to make your smartphone work like a clock.
Activation and fine-tuning of Game Turbo
The centerpiece of the gaming experience on Xiaomi devices is the built-in Game Turbo utility (formerly known as Game Center), which is not just an application launcher, but a powerful resource management tool for the system. By default, it can work in gentle mode, so it must be manually configured to get priority in power distribution.
To access advanced settings, run any game through the shortcut in the Security app or find the Game Turbo floating button on the screen. Here, it is important to pay attention to the performance profile. Switch it to Speed or Performance mode so that the system stops limiting the CPU frequency for the sake of saving energy.
☑️ Setting up the Game Turbo
In the optional settings menu (often hidden behind the menu button or swipe), you can find parameters that affect the sensor response. Increased touch sensitivity helps to respond faster in shooters such as PUBG Mobile or Call of Duty. It also offers a feature to block third-party notifications, which prevents sudden lags when messages from instant messengers arrive.
⚠️ Warning: Enabling maximum performance mode may cause the body to heat up.Watch the temperature of the device during long gaming sessions.
Cleaning RAM and Process Management
RAM is a critical resource for modern games. MIUI tends to keep a lot of background applications in mind to run them quickly, but it steals megabytes from a running game.
Use a built-in memory cleaner available through recent app menus or a desktop widget. However, single-button mechanical cleaning is not always effective, as some processes restart instantly. It is better to manually close resource-intensive applications such as social networks, navigators and open-tab browsers.
- 🚀 Close all background apps through the multitasking menu before start.
- 📉 Turn off data synchronization and auto-update applications in the background.
- 🔋 Turn your phone into Do Not Disturb mode to turn off network requests.
There is also a hidden memory extension feature that uses a portion of internal storage as virtual RAM, which can be found in Settings → Expansion of memory. While this can help devices with low RAM (3-4 GB), on fast drives, the effect can be minimal, and memory wear can increase.
Should I include memory expansion?
Optimization of graphical settings and refresh rates
Image quality directly affects the load on the GPU. Many users mistakenly set maximum graphics settings, not considering that the screen of the smartphone has a limited resolution. Decreasing the quality of textures and shadows often gives an increase of 10-15 FPS without visible loss of quality on the small screen.
If your Xiaomi supports 90Hz or 120Hz, make sure that the display settings (Settings → Screen → Update Frequency) have a default or 120Hz value. However, in some cases, setting a fixed 60Hz can stabilize older games that are poorly optimized for high hertz.
In-game settings also require attention, such as turning off anti-aliasing and dynamic shadows, which create a beautiful picture, but require a lot of computing power, and in competitive games, clarity and speed are more important than photorealism.
| Parameter | Impact on FPS | Recommendation |
|---|---|---|
| Rendering permission | High. | Reduce to 0.8 or 0.9 from native |
| Shadows. | Average. | Turn off or put "Low" |
| Smoothing | High. | Turn it off. |
| Post-processing | Low. | Leave on (little impact) |
💡
Some games have hidden configuration files that allow you to unlock 90 FPS on unsupported devices, but using them can lead to a ban of an account.
Energy and Temperature Management
Trottling is the automatic processor frequency reduction when overheated, which is the main enemy of stable gaming. Xiaomi smartphones have strict temperature limits. When the case heats up, the system artificially "strangles" performance to avoid damage to components.
To delay the onset of trottling, remove the protective case while playing. Dense silicone or leather cases work as a thermal insulator, preventing heat from coming out, and avoid playing in direct sunlight or in bright light, which additionally heats the screen.
In the battery settings (Settings → Battery) for gaming applications, you can set the No Limits mode, which will prevent the system from forcibly closing the game or reducing its priority even if the battery is dead or the phone is hot, but this speeds up discharge and heating.
Using external coolers for smartphones is a radical but effective method, and active cooling allows the processor to work at maximum frequencies for a long time without resetting the clock, especially for console emulators or heavy games like Genshin Impact.
Cleaning the storage and cache of the system
A filled internal storage is one of the common causes of slowing down the entire system, including games. When the free space runs out, the system does not have enough space to create temporary files and swaps, and it is recommended to keep 10-15% of the total memory free.
Clean the cache of apps regularly, especially those you don't use daily. MIUI has a built-in Cleanup tool that finds junk files. It's also helpful to remove old downloads, screenshots and videos that take up gigabytes of space.
- 🗑️ Remove unused apps that take up space and hang in the background.
- 📂 Transfer photos and videos to a cloud service or computer.
- 📲 Use the Deep Cleanup feature in the Security app.
If you haven’t updated your system in a while or upgraded to a raw version of Android, you may need a full reset, which is an extreme measure, but it often brings the phone back to its former snooze by removing all system errors and setting conflicts.
⚠️ Note: Before performing a full reset (Wipe Data), be sure to back up all important data, as they will be irretrievably deleted.
Hidden developer settings for gamers
For advanced users, the Developer Menu is available, which contains options that affect animations and background processes, and you can get there by clicking on the build number several times in the About Phone section.
In this menu, find a section related to drawing: Reducing the scale of window animations, transitions and animator duration to 0.5x or 0x will make the interface more responsive. It won't add FPS to the game, but it will speed up switching between windows and launching the game.
adb shell settings put global window_animation_scale 0.5
adb shell settings put global transition_animation_scale 0.5
adb shell settings put global animator_duration_scale 0.5You can also find the Background Process Limit setting here, which means that setting a limit on the number of background processes (e.g., no more than 2) will help free up RAM, but beware: this can disrupt messengers and alarm clocks.
💡
Changes to the developer menu can affect the stability of other applications, so remember the initial values to get things back to normal.
Another useful parameter is disconnection. HW-In the developer menu, find the item "Disable overlay" HW» And activate it. GPU handle all the graphics, which in some cases can improve performance but increase energy consumption.
