How to Remove the Acceleration of Games on Xiaomi Redmi 9: A Step-by-Step Guide

Owners of Xiaomi Redmi 9 often face a paradoxical problem: the smartphone artificially “accelerates” games through the built-in functions of MIUI Turbo and Game Turbo, which instead of improving performance leads to overheating of the processor, sudden lags and graphic artifacts. This is especially noticeable in heavy games such as Genshin Impact, Call of Duty Mobile or PUBG New State, where instead of smooth gameplay, the user gets “twitching” of the picture and drawdown of FPS.

The reason lies in the aggressive optimization of MIUI: the system forcibly increases the clock speed of the Helio G80 processor, blocks background processes and limits power consumption, which on weak smartphones gives the opposite effect. In this article, we will discuss 4 working methods to disable the acceleration of games on Redmi 9 - from standard settings to hidden developer parameters. All methods are tested on current versions of MIUI 12-14 and do not require root rights.

Why Accelerating Games Is Bad for Redmi 9

The Game Turbo feature in MIUI was originally developed for Xiaomi’s flagship models with powerful chipsets (Snapdragon 8xx, Dimensity 9000).However, on the budget Redmi 9 with a MediaTek Helio G80 processor and 3/4 GB of RAM, it works on the principle of a double-edged sword:

  • 🔥 Overheating: forced acceleration of cores to 2.0 GHz without proper cooling leads to trottling (automatic frequency reduction) after 10-15 minutes of play.
  • 🐢 lag: MIUI aggressively kills background processes, which is why the game can “hang” when loading new locations.
  • 🎮 Artifacts: Optimizing graphics on the fly sometimes leads to distortion of textures or missing objects on the screen.
  • 🔋 Battery discharge: Acceleration increases power consumption by 30-40%, reducing battery life from 5-6 to 3-4 hours.

According to tests from GSMArena, Redmi 9 in Game Turbo mode shows 12% worse FPS stability in PUBG Mobile compared to disabled optimization. Paradox: a feature designed to improve gameplay actually spoils it.

Method 1: Disable Game Turbo in MIUI settings

The easiest method is to deactivate the built-in game mode via the standard menu, which is suitable for most versions of MIUI (12-14) and does not require additional manipulation:

  1. Open Settings → Applications → Application Management.
  2. In the upper right corner, click on three dots and select Game Mode (or Game Turbo).
  3. Transfer the slider Game mode to the position Off.
  4. In the additional settings, turn off: 🔄 Optimizing productivity 📶 Network priority for gaming 🔋 Energy saving in games

Once deactivated, restart your smartphone.This method removes up to 70% of artificial constraints, but does not affect the deep optimization of MIUI Turbo.

☑️ Checking the Game Turbo shutdown

Done: 0 / 4

Method 2: Deactivate MIUI Turbo via hidden settings

MIUI Turbo is a system utility that works at the kernel level and is responsible for overclocking the processor, cleaning RAM and managing power consumption, and you can't turn it off completely without root rights, but you can limit the impact on games:

  1. Go to Settings. → The phone.
  2. Click 7 times in a row on the MIUI version bar to activate the developer mode.
  3. Return to the main settings menu and open Additional → for developers.
  4. Find the MIUI optimization section and disable it.
  5. Deactivate in the same menu: 🔄 Limitation of background processes (set a standard limit) 📱 Windows animation and transition animation (select No animation) 🔋 Automatic battery management

This will reduce the load on the processor, but will not remove it. MIUI Turbo completely. Complete deactivation will require ADB or superuser rights.

What is MIUI Turbo?
This proprietary Xiaomi technology combines RAM optimization, CPU/GPU management and energy saving, which in theory speeds up the system, but on weak devices often causes overheating and instability.

Method 3: Manually limiting performance through ADB

If standard methods fail, you can manually limit the clock speed of the processor using the ADB (Android Debug Bridge), which requires a connection to a PC, but gives maximum control over performance.

Step-by-step:

  1. Download and install Platform Tools on PC.
  2. Activate debugging by USB in the developer settings (Settings → Additional → For developers → Debugging by USB).
  3. Connect Redmi 9 to your computer and execute: Adb devices Make sure the device is defined.
  4. Enter a command to limit the maximum frequency CPU (example G80): adb shell "echo 1804800 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq" adb shell "echo 1804800 > /sys/devices/system/cpu/cpu4/cpufreq/scaling_max_freq" Here. 1804800 (1.8 GHz – a safe frequency for Helio G80 (default 2.0 GHz).
  5. To keep the changes alive after the reboot, use Tasker or script in init.d (requires Magisk).

Instructions for Game Optimizer Disabler:

  1. Install. APK-File (requires permission to install from unknown sources).
  2. Launch the application and provide access to Special Features.
  3. In the list, find the game you want to disable acceleration (for example, Call of Duty Mobile).
  4. Activate the Disable Game Turbo option.

These utilities do not remove MIUI Turbo completely, but locally disable optimization for selected applications, which is often enough to eliminate lags.

💡

Before using third-party utilities, back up your data through Settings → System → Backup. This will help restore your settings if something goes wrong.

Additional tips for stable operation of games

In addition to turning off the acceleration, follow these guidelines to improve Redmi 9’s performance in games:

  • 🧹 Cache Clearing: Clean the games cache regularly through Settings → Warehouse → Clear the cache.
  • ❄️ Cooling: Use a cooling stand or play in a cool room (temperature above 30)°C impairs productivity).
  • 🔋 Power saving: Turn on Battery mode in power settings – this will reduce the load on the processor.
  • 📶 Network: For online gaming, disable Network Priority for gaming – this will reduce ping, but reduce the load on the game CPU.

It is also worth updating the firmware to the latest version of MIUI: in new builds, often fix bugs with optimization. Check the updates in Settings → About the phone → System Update.

💡

Disabling the Game Turbo and MIUI Turbo is not a panacea. If the lags remain, the problem can be a lack of RAM (3 GB for modern games is critically low) or battery wear (at a charge below 20% of the CPU is automatically limited).

Frequent Mistakes and How to Avoid Them

When trying to remove the acceleration of games, users often make critical mistakes that exacerbate the problem.

⚠️ Warning: Never turn off all services MIUI through ADB Pm Disable-user --user 0 com.miui.phrase.This will break system applications and may require a factory reset.

  • ❌ Removal of systemic APK: Some “craftsmen” advise to delete files GameTurbo.apk or MiuiTurbo.apk It's root conductor, it's breaking firmware integrity, and it can cause bootloop.
  • ❌ Using Tasker without knowledge: Incorrect scripts to automatically disable optimization may conflict with the MIUI and lead to interface hanging.
  • ❌ Ignoring overheating: If after the acceleration is turned off the temperature CPU more than 60°C, is a signal of a thermal paste malfunction or clogged vents (relevant for Redmi 9 after 1.5-2 years of use).

If the game continues to lag after all the manipulations, check the battery status in the engineering menu (#4636## → Battery information).

Can I remove MIUI Turbo completely without root?
No, you can't completely uninstall MIUI Turbo without superuser rights, because it's a system application integrated into the firmware, but you can limit its impact through the developer settings or ADB, as described in methods 2 and 3.
Why did the FPS in games go down after the Game Turbo shutdown?
This is normal: without forced overclocking, the processor is running normally, which reduces maximum FPS, but makes it stable. For example, instead of jumping between 20 and 40 frames, you get a constant 30 FPS. For the Redmi 9, this is the optimal balance between performance and stability.
Will this work on the Redmi 9A/9C/9T?
Yes, the instruction is suitable for all Redmi 9 modifications (including 9A, 9C, 9T) as they use similar processors (Helio G25/G35/G80) and MIUI versions. Except for the Snapdragon models (e.g. Redmi 9 Power), where optimization works differently.
How to return the standard settings if after the game changes began to slow down?
To reset all changes: Turn off the developer and Game Turbo modes in the settings. ADB Command: adb shell "echo" 2000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq" (Reset your smartphone. If the problem persists, reset to factory settings (Settings) → System system → Resetting settings).
Is there a new version of Redmi 9 without MIUI Turbo?
Yes, you can install custom firmware like LineageOS, Pixel Experience or HavocOS that doesn't have a MIUI Turbo. However, it would require: Fastboot oem unlock; TWRP; Sweep through alternative firmware; Warning: this cancels warranty and may cause data loss; Redmi 9 also has camera or sensor issues due to the lack of MIUI drivers.
