How to Enable Game Booster on Xiaomi: A Complete Guide to Settings

Game Booster (or Game Turbo in newer versions of MIUI) is Xiaomi’s proprietary technology that optimizes smartphone performance during games. It automatically frees up RAM, blocks notifications, improves sensor response, and even reduces CPU heat. But many users don’t know that this tool needs to be turned on, but also properly configured for specific games.

In this article, you will find current ways to activate the Game Booster on all versions of MIUI (including MIUI 14/15), as well as hidden chips that the manufacturer does not advertise. We will learn how to turn on the mode for individual games, adjust the performance manually, and even how to circumvent the restrictions on some Poco and Redmi models, where the function can be hidden by default.

What is a Game Booster and Why You Need It

Game Booster is not just a "game mode," it's a whole set of optimizations that work at the system level.

• 🔄 Dynamic resource allocation: CPU and GPU Automatically accelerate to maximum frequencies when necessary and reduce the load in the background processes.
• 📵 Block notifications: During the game you will not be distracted by messages from messengers or calls (unless you set exceptions).
• 🔥 Temperature control: The system limits processor heating to avoid trottling (decreased performance due to overheating).
• 🎮 Sensor optimization: Reduces touch delay, which is especially important in shooters. PUBG Mobile or Call of Duty.

On the new flagships (Xiaomi 14, Redmi K70 Pro), the Game Booster is integrated with HyperOS technology, which provides additional features, such as adaptive screen refresh rates. And on budget models (Redmi Note 12, Poco M6 Pro), it helps to compensate for weak iron due to software optimizations.

⚠️ Note: On some devices (especially custom firmware) Game Booster may conflict with root rights or Magisk modules. If after activation, games begin to fly out - check the logs through adb logcat.

How to turn on Game Booster on Xiaomi: step-by-step instructions

The way you activate it depends on the MIUI version and the smartphone model, and we'll look at all the options, including hidden settings.

Method 1: Through system settings (MIUI 12 and later)

This is the easiest method that works on most devices:

1. Open Settings → Special features → Game Turbo
2. Activate the "Enable Game Turbo" switch.
3. In the list of games, select the ones you want to apply optimizations for (or click "Add Games" if the right one is not in the list).
4. Set up the parameters: 🔹 Performance: Choose Balance, Performance or Charge Savings. 🔹 Effects: Turn on or off vibrations, sounds and backlights. 🔹 Screen recording: Set up resolution and bitrate for streams.

Close all background applications |Plug in charger (recommended) |Check out available space on the device (minimum 2GB) |Update MIUI to the latest version-->

Method 2: Through the notification panel (fast access)

If you play frequently, add the Game Turbo shortcut to the curtain:

1. Swipe down to open the notification panel.
2. Click on the "Edit" icon (pencil).
3. Find the Game Turbo tile and drag it to the active area.
4. Now you can turn on the single tap mode before starting the game.

On some models (Poco F5, Redmi Note 13 Pro+) the tiles may be called "Game Mode" or "Game Space".

Method 3: For older versions of MIUI (up to MIUI 11)

On devices with MIUI 9/10 (e.g. Redmi Note 7, Mi 8), the Game Booster was called the "Game Accelerator" and was located elsewhere:

Settings → Additional → Game accelerator

If this item is not available, try updating the firmware or using an alternative method via Security:

1. Open the Security app (Security).
2. Go to Optimization. → Game accelerator.
3. Turn on the mode and add games manually.

Game Booster’s Hidden Settings: How to Make the Most of It

Few people know, but Game Turbo has advanced options that don't show up by default, and you can activate them through an engineering menu or special gestures.

How to open hidden settings

For devices on MIUI 13/14:

1. Open Game Turbo and select any game from the list.
2. Slip 5 times on the Settings icon (cog in the upper right corner).
3. The Lab menu will appear with additional options: 🔹 GPU Rendering: Forced use of graphics accelerator. 🔹 4D Viibration: Improved Vibration for Games (not working on all models). 🔹 Network Boost: Priority for Gaming Traffic (Helpful for Online Shooters).

On HyperOS (e.g. Xiaomi 14), hidden settings are opened via Settings → About Phone → MIUI version (tap 7 times on the build number, then return to Game Turbo).

Optimization for specific games

Game Booster allows you to create customized profiles for each game, for example, for Genshin Impact you can set maximum performance, and for Clash Royale - a mode of saving charge.

Game Booster Problems and Solutions

Despite all the benefits, users often encounter bugs, and here are the most common problems and ways to fix them:

Game Booster is not included

If the switch is inactive or the mode is not applied:

• 🔋 Check the battery power – on some models (Redmi Note 11) the Game Turbo only works at a charge above 20%.
• 🔄 Restart the device and try again.
• 📱 Update. MIUI up to the latest version (in old builds there are bugs with game mode).
• 🛠️ Reset the Game Turbo settings: Settings → Annexes → Application management → Game Turbo → Warehouse → Clear the data.

Games are laid down after the Game Booster is turned on

Paradoxically, sometimes optimizations backfire.

• 🔥 Overheating: If CPU Trottlit (reduces frequency due to high temperature), try: Use a cooling stand. Reduce the settings of the graphics in the game. Enable "Temperature Limit" in the Game Turbo settings.
• 🗑️ Memory Lack: Close all background apps through Settings → Annexes → Launched.
• 🔄 Conflict with other accelerators: Disable applications like GFX Tool or Game Guardian.

⚠️ Note: On devices with MediaTek Helio G (e.g. Redmi) 9A) Forced overclocking through the Game Booster can lead to graphic artifacts in Unreal Engine games. In this case, select Balance profile instead of Performance.

Game Booster does not save settings

If after restarting the device settings are reset:

1. Check if root rights are set, they can block system optimizations.
2. Turn off the "Adaptive Battery" in Settings → Battery.
3. Reset Game Turbo cache via Settings → Storage → Clear cache.

💡

If the Game Booster doesn't work for Poco F3 or Redmi K40, try to install EU-The game mode is optimized better than in the global version.

Game Booster Alternatives: What to Do If You Don't Have One

Some devices (like the Poco M4 Pro on older firmware) may not have the Game Booster, in which case you can use third-party utilities or system tricks.

Third-party utilities to speed up games

Popular alternatives:

• 🎮 GFX Tool: Allows you to change permission, FPS and graphical settings in games on Unity and Unreal Engine.
• ⚡ Game Guardian: Modifies game settings (e.g. increases speed of movement in shooters).
• 🔥 CPU Tuner: Manual control of processor frequencies (requires root).

Caution: Using modifiers can lead to account bans in online games (e.g., PUBG Mobile or Free Fire).

System tricks without Game Booster

If you don’t want to install third-party apps, try:

• 🔄 Insert "Performance Mode" in Settings → Battery → Regimes.
• 🗑️ Clear the cache through Settings → Warehouse → Clean up.
• 🔋 Disable Battery Optimization for Gaming Applications.
• 📱 Use "Safe Mode" (hold the power button) →"Safe mode") to temporarily disable background processes.

💡

On devices with Snapdragon 8 Gen 2 (such as Xiaomi 13 Pro), Game Booster works more efficiently than third-party utilities, thanks to deep integration with Qualcomm drivers.

How to turn off Game Booster (and when you need it)

Despite all the advantages, sometimes the game mode is better to turn off:

• 🔋 If you are playing with a battery and want to save money.
• 🔥 If the device is very hot (for example, on the Redmi Note 10 Pro with Snapdragon) 732G).
• 🎮 If the game itself is well optimized (e.g. Minecraft or Brawl Stars).

To turn off the Game Booster:

1. Go to Settings → Special features → Game Turbo.
2. Turn off the main switch.
3. Remove the games from the list (optional).

On some models (Poco X4 Pro) after disabling Game Turbo games can start with a delay – this is normal, as the system resets the priorities of the processes.
