Xiaomi Redmi Note 9 with its MediaTek Helio processor G85 4 GB of RAM is able to confidently pull modern mobile games - from PUBG Mobile to Genshin Impact. But without the right settings, even powerful hardware can let you down: friezes, overheating or sudden notifications at the most critical moment. Here comes the built-in game mode, which optimizes the system for high loads.

In this article you will find not just the instructions “where to press”, but a full guide to fine-tuning the game mode on the Redmi Note 9, taking into account the features of the game. MIUI 12-14. We'll look at how to turn on the function through the menu and quick settings, what parameters really affect the function. FPS, We also reveal little-known features, such as how to prioritize resources for a particular game or disable automatic performance restriction when heated.

Important: on different versions MIUI The menu layout may be slightly different, but the logic remains the same. If you have a Redmi Note 9 Pro or other model of the series, the instruction will fit with an iron correction (for example, the Note 9 Pro Snapdragon processor). 720G, What gives additional optimization options).

What is a game mode on Xiaomi and why is it necessary?

In-game mode MIUI — It's not just a marketing tool, it's a set of optimizations that are activated when a game is launched:

• 🔧 Hardware: increases the clock speed of the processor and graphics accelerator, blocks the decrease in performance due to overheating (within reasonable limits).
• 📱 Software: Disables background processes, limits notifications, and blocks random touches on the screen (for example, when you hold your smartphone in a horizontal position).
• 🎮 Gaming: Adds floating panels for quick access to brightness settings, FPS-counter-record.

On the Redmi Note 9, game mode is especially important due to the features of the Helio processor. G85: It is prone to trottling (automatic frequency reduction) when heated above 45.°C. Without activation, the game can begin to lay after 15-20 minutes of intense session. With the mode on, the threshold of trolling shifts to 50-55°C, and background apps don't steal precious resources.

⚠️ Warning: Continuous use of game mode in resource-intensive games (for example, Call of Duty Mobile at maximum settings) reduces battery life by 20-30.

Interesting fact: in MIUI 14 Game Turbo, which analyzes game behavior and adjusts settings in real time, is available. On the Redmi Note 9, it doesn't work as efficiently as on flagships, but it still gives you stability gains. FPS 5-10%.

Step-by-step setting up the game mode for maximum FPS

Just turning on the game mode is not enough – to get a real performance boost, you need to adjust it to a specific game.

Insert “Optimization of productivity"|Deactivate "Limitation" FPS"|Activate "Blocking Notifications"|Insert "Tactile recoil" for shooters|Set the screen brightness to 80-90%-->

1. Optimization of productivity

In the section Game mode → Performance settings:

• 🔥 Performance Mode: Choose High (for Genshin Impact) or Balanced (for Genshin Impact) PUBG Extremely incremental. FPS, but the processor is warm.
• 📊 Limitation FPS: Disable if the game supports a high frame rate (for example, Call of Duty Mobile at 60). FPS).
• 🔄 Memory Cleanup: Turn on automatic background cleaning when you start the game.

2. Screen and sensor settings

In the section Game mode → Display and control:

• 🌡️ Brightness: set 80-90%. Too high brightness increases the load on the processor.
• 👆 Random touch lock: turn it on if you play horizontally (e.g. Asphalt 9).
• 🎯 Sensor sensitivity: for shooters (such as Free Fire) increase to 120-150%.

3. Additional chips

Little-known features that give an advantage:

• 🔊 Sound effects: turn on 3D-sound for better positioning of enemies in shooters.
• 📶 Network: Activate Network Priority to Reduce Online Ping.
• 📹 Screen recording: set up hotkeys to quickly save key moments.

⚠️ Warning: if after activation of the game mode, the smartphone begins to warm up strongly (above 50)°C), return to the settings and turn on Temperature Limit at 45°C. This will reduce performance by 5-10%, but save the battery from degradation.

How to add a game to the list of game mode (if it is not there)

Sometimes. MIUI It does not recognize the game as such (e.g., emulators or obscure projects) to manually add the app to the list of game modes:

After that:

1. Select Phone Information.
2. Scroll down to the Battery Settings section.
3. Slip on the Engineering Settings Menu (could be called Engineer Mode).

Useful settings for gamers

In the engineering menu, pay attention to the following parameters:

• 🔥 Thermal Engine: You can increase the trottling threshold from 45°C to 50-55°C (but it will shorten the life of the processor).
• 📊 GPU Rendering: Enable Force GPU Rendering to speed up graphics (can increase battery consumption).
• 🔄 Background Process Limit: Install No background processes to free up maximum RAM.

💡

Before changing the settings in the engineering menu, back up the settings in Settings. → Additionally. → Backup. It'll help restore the system if something goes wrong.

⚠️ Attention: parameter changes CPU Frequency or Voltage Control in the engineering menu can cause overheating, sudden reboots or even damage to the processor.

For Redmi Note 9, the optimal settings in the engineering menu:
