How to update the acceleration of games on Xiaomi: FPS overclocking, MIUI optimization and hidden chips for gamers

Xiaomi smartphones are one of the most popular devices for mobile gaming due to the powerful hardware and aggressive pricing policy. However, even flagship models like Xiaomi 14 Ultra or Black Shark 6 Pro eventually begin to “slow down” in modern games such as Genshin Impact, Call of Duty Mobile or the “Call of Duty” game. PUBG New State.The reason isn't always a weak processor - restrictions are often to blame MIUI, background processes or incorrect graphics settings.

In this article, we’ll look at 7 working ways to speed up games on Xiaomi, including hidden firmware features, ADB overclocking, cooling optimization, and even configuration file modifications. All methods have been tested on devices with MIUI 14/15 and HyperOS, but most of them work on older versions as well. Importantly, some tricks require unlocking the bootloader or superuser rights — we’ll warn you of the risks in advance.

If you want to not only increase FPS, but also reduce heat, reduce input lag, and extend battery life during gameplay, read on. Start with the safest methods and gradually move to heavy artillery.

1. Enable Game Turbo Mode and Hidden MIUI Settings

Game Turbo is Xiaomi’s proprietary technology for optimizing games, but by default it doesn’t work at full capacity. Many users don’t even realize that there are additional switches hidden in this mode that can increase FPS by 10-15% without risk to the system.

How to activate the full potential of Game Turbo:

• 🎮 Open any game, then swipe from top to bottom on the left or right edge of the screen to call the Game Turbo panel.
• ⚙️ Click on the gear icon ("Settings») → Select the Productivity item.
• 🔥 Enable options: Maximum performance (disables clock limit) CPU/GPU) Touch optimization (reduces input lag) Notification blocking (prevents friezes due to background processes)
• 📊 In the Graphics section, select High Quality (even if the game itself offers "medium" settings - it is a deceptive parameter).

On HyperOS devices (such as Xiaomi 14 or Redmi K70), the path is a little different: Settings → Applications → Game Turbo → Lab. Here is a new item Gamer Mode 5.0, which automatically allocates resources between the game and the system. Activating this option on Snapdragon 8 Gen 3 gives an increase of up to 20% in 3DMark tests.

⚠️ Note: On some models (POCO F5, Redmi Note 12 Pro+) When the maximum performance is turned on, the device starts to warm up more.°C, use a cooling stand or reduce the load manually.

2. Acceleration through ADB: We're off limits MIUI on FPS

By default, MIUI artificially limits the number of frames per second (FPS) in games, even if the hardware is capable of delivering more, which is done to save battery power and prevent overheating, but with ADB commands you can turn off those limits and overclock the graphics.

Instructions for Windows/macOS/Linux:

1. Turn on Developer Mode: Go to Settings → About Phone. Click 7 times on MIUI Version until the notification “You’ve become a developer” appears.

USB debugging

• Back to Settings → Additionally. → For developers.
• Turn on the USB debugging switch and confirm the resolution.
• Connect your phone to your PC and execute the commands: adb shell settings put global force_high_perf true adb shell settings put global force_fps 120 The first command forces the system to use maximum performance, the second - fixes FPS level 120 Hz (if the screen supports). 90 Hz replace 120 on 90.

Once you've applied the commands, restart the device. To get it back, use:

adb shell settings put global force_high_perf false


adb shell settings put global force_fps 0

Install ADB drivers on PC

Enable the developer mode

Activate debugging over USB

Connect your phone to the original cable

Check the connection with the team `adb devices`-->

⚠️ Note: On devices with a MediaTek processor (such as the Redmi Note 13 Pro), these commands may not work due to the closed chipset architecture. MTK Engineering Mode (available on Google Play).

3. Optimizing cooling: how to prevent trottling

Trottling (automatic performance decline when overheating) is the main reason for the fall of FPS in long game sessions. Xiaomi uses aggressive cooling algorithms that work already at 42-45 ° C. Fortunately, this can be bypassed.

Ways to combat overheating:

• ❄️ Cooling accessories: Use Black Shark FunCooler Pro (suitable for most Xiaomi models) Phase transition stickers (e.g. Cooler Master Mobile Cooling Pad).
• 🔧 Software Methods: Turn off Automatic Temperature Control in Settings → Battery → Modes. Install the app. CPU Throttling Test (shows the actual core temperature).
• 🛠️ Extreme measures (requires root): Replace the heat paste on the processor (relevant to the processor) POCO F3/F4, wherein the factory paste dries 1-2 Edit the file. /system/vendor/etc/thermal-engine.conf, increasing the thresholds of trottling.

On the Black Shark series, you can manually adjust the speed of the built-in fan through the SharkSpace application - this gives +5-7 FPS in resource-intensive games.

💡

Before a long game session, cool your phone in the fridge (not freezer!) for 10-15 minutes, which will increase the time to the first trottling by 20-30%.

4. Modification of the build.prop file: hidden overclocking of the GPU

The build.prop file contains Android system settings, including the graphics accelerator settings. Changing a few lines can overclock the GPU by 10-15%, but this requires root rights and system backup.

Step-by-step:

1. Make a backup build.prop (located in /system/build.prop).
2. Open the file in a text editor (such as Root Explorer).
3. Add or change the following lines: debug.performance.tuning=1 debug.egl.hw=1 debug.sf.hw=1 debug.composition.type=gpu persist.sys.ui.hw=1 ro.surface_flinger.max_frame_buffer_acquired_buffers=3 ro.min_pointer_dur=8
4. Save the file, set the rights 644 (rw-r--r---).
5. Reset the device.

These parameters:

• 🔄 Include hardware acceleration rendering (debug.egl.hw)=1).
• 🎯 Increase the staff buffer (ro.surface_flinger.max_frame_buffer_acquired_buffers=3).
• ⚡ Reduces the delay in touching (ro.min_pointer_dur=8).

⚠️ Warning: Incorrect editing build.prop can lead to bootloop.If the phone doesn't turn on after the changes, restore the backup via TWRP or re-flash the device.

5.Switching off MIUI Optimizations: Why it speeds up games

MIUI Optimizations is a set of background services that supposedly “optimize” the system, but in practice often interfere with games by blocking access to full CPU power.

How to Deactivate MIUI Optimizations:

1. Install ADB (see Section 2).
2. Connect the phone and execute the command: adb shell pm disable-user --user 0 com.miui.powerkeeper
3. For full effect, also disable: adb shell pm disable-user --user 0 com.miui.analytics adb shell pm disable-user --user 0 com.xiaomi.midrop
4. Reset the device.

What this blackout does:

• 🚀 Removes artificial clock frequency restrictions CPU/GPU.
• 🔋 Prevents sudden falls FPS background-problem.
• 📱 Reduces delays when changing apps (good for streamers).

On devices with HyperOS (e.g. Xiaomi 14), com.xiaomi.powerkeeper can be used instead of com.miui.powerkeeper – check the current name of the package through the command:

adb shell pm list packages | grep power

💡

Disabling MIUI Optimizations is particularly effective on devices with Snapdragon 888/8 Gen 1, where standard MIUI settings greatly understate performance due to overheating issues.

6. Use of custom cores and firmware

If standard methods don’t add enough, you can go further and install a custom core or firmware optimized for gaming, which is only suitable for advanced users, as it requires unlocking the bootloader and risks voiding the warranty.

The best solutions for gamers:

Instructions for the installation of the custom core:

1. Unlock the bootloader through the Mi Unlock Tool (requires a wait of 7-15 days for new accounts).
2. Install TWRP Recovery for your model.
3. Download the kernel (e.g. Kiran Kernel for POCO F4) from the XDA Developers forum.
4. Reboot to TWRP, backup, then run the kernel through Install → Select file → Swipe to Confirm.
5. Clear the cache (Wipe) → Dalvik/ART Cache and reboot.

⚠️ Note: On HyperOS devices (e.g. Xiaomi 14), unlocking the bootloader can result in blocking the data encryption.

7. Battery and background processes optimization

Even if you overclocked the hardware, background processes and improper battery settings can negate all efforts.MIUI is known for aggressively closing applications in the background, but for games this is often harmful - for example, discord or government services can be interrupted at the most inopportune moment.

How to set up the battery for maximum performance:

• 🔋 Turn off the Adaptive Battery: Go to Settings → Battery → Select High Performance (not Balanced»!).
• 🚫 Stop optimizing for games: Open Settings → Annexes → App management. Select a game (e.g. Genshin Impact) → Battery → No restrictions.
• ⚡ Use Greenify (requires root) to force hibernation of unnecessary apps: Add to the hibernation list of MiuiDaemon, Analytics, MSA. Remove the launcher and gaming applications from the list.

For HyperOS devices, a new feature called Deep Optimization (Settings → Battery → Deep Optimization) has been introduced, and it must be turned off because it closes games whenever there is a shortage of resources.

💡

If the game starts to lay after 10-15 minutes of gameplay, check the battery temperature. If it exceeds 40 ° C, temporarily turn off fast charging - this will reduce heating by 5-10 °.
