Disabling the acceleration of games on Xiaomi Redmi Note 4: the full guide

Xiaomi Redmi Note 4 is still a popular smartphone among gamers due to the balance of performance and price. However, many users face a problem: the built-in gaming acceleration features from MIUI do not always work correctly. Instead of smooth gameplay, you get slowdowns, overheating or unstable FPS. What is the reason and how to fix it?

The fact is that MIUI automatically applies aggressive optimizations to games that may conflict with specific application settings, such as forcefully increasing the CPU clock speed or blocking background processes sometimes backfires, and in this article we will look at all the ways to turn off the acceleration of games, from standard settings to hidden parameters of the engineering menu.

Why Accelerating Games Can Hurt Productivity

At first glance, the game acceleration function should improve the experience, but in practice, it often leads to:

• 🔥 Overheating of the processor due to forced acceleration without proper cooling.
• 🐢 Laham and Frisians when the system kills background processes too aggressively.
• 🔋 Fast battery discharge – acceleration holds the cores CPU maximum-frequency.
• 🎮 Unstable. FPS in games where smoothness is important (for example, in PUBG Mobile or Call of Duty).

The problem is especially relevant for the Redmi Note 4 with the Snapdragon 625 processor, which is not designed for long-term loads with forced overclocking, so after 15-20 minutes of play, performance drawdowns begin.

MIUI can also misidentify games as "heavy" and apply optimizations where they are not needed, such as Among Us or Brawl Stars, which do not require high performance.

Method 1: Disabling acceleration through MIUI settings

The easiest method is to use the built-in MIUI options, which is suitable for most users and does not require root rights.

1. Open Settings → Special Opportunities → Accelerate Games
2. Switch the slider to the off position.
3. Reboot your smartphone so that the changes take effect.

If your version of MIUI does not have the option of Accelerating Games in the Special Opportunities, try an alternative way:

• 📱 Open the Settings. → Annexes → Application management.
• 🔍 In the search, type the name of the game (for example, Genshin Impact).
• 🚀 Put it on the battery. → Speed up games and turn off the option.

Note that in some firmware, this may be called Performance Optimization or Game Mode. If you don't find it, move on to the next way.

Method 2: Use of the Engineering Menu (without root)

If standard settings don't work, you can use the engineering menu, which works on most versions of MIUI, but you need to be careful, because the wrong changes can cause failures.

Instructions:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that opens, select Battery Information.
3. Scroll down and find Game Optimization (or Game Booster).
4. Turn off all speed-related sliders.
5. Save the settings and restart the device.

In some firmware, the path may be different. If the ##4636## combination doesn't work, try:

• 🔧 Enter ##36446337## (to check the version of the engineering menu).
• 📱 Use the application MTK Engineering Mode (available on Google Play for MediaTek devices).

💡

If after changes in the engineering menu, the smartphone began to slow down, reset the settings to the factory through Settings → Additional → Recovery and reset.

Method 3: Disconnect via ADB (for power users)

If previous methods have not worked, you can use them. ADB-It's a more complicated way, but it gives you access to hidden settings. MIUI.

What you need:

• 🖥️ A computer with installed Xiaomi drivers and ADB.
• 📋 Included Debugging by USB on a smartphone (Settings) → The phone. → Version. MIUI — Tap 7 times, then return to the additional → For developers).
• 🔌 Cable USB (preferably original).

Step-by-step:

1. Connect Redmi Note 4 to your PC and open the command line (Win + R → cmd).
2. Enter the command to check the connection: Adb devices should appear the name of your device.
3. Execute the command to disable the game acceleration: adb shell settings put global game_booster_enable 0
4. Reboot your smartphone.

To return the settings back, use the command:

adb shell settings put global game_booster_enable 1

Comparison of methods: what way to choose

Not all methods are equally effective. Below is a table comparing the pros and cons of each approach:

For most users, the first or second method is enough. ADB should only be used if you are confident in your actions or other methods have not helped. Apps from Google Play (such as the Game Booster or GFX Tool) often promise miracles, but in practice are ineffective.

💡

If after turning off the acceleration, the games began to work worse, try manually adjusting the graphics in the game itself (lower the resolution or turn off the shadows).

Additional settings for stable FPS

Turning off the acceleration is only part of the solution. To achieve a truly smooth gameplay on the Redmi Note 4, we recommend:

• ⚙️ Disable System Animation: Go to Settings → The phone. → Version. MIUI (tap 7 times to activate the developer mode. → For developers, find the boxes: Window animation scale, transition animation scale, and animator duration scale. Set the value to turn off animation for all three.

Limit background processes

In the same developer menu, find the Process Limit and set the Standard Limit (or No Background Processes if the game is severely slowing down).

Lower screen resolution

In the game graphics settings (for example, in PUBG Mobile), select Smooth or Balanced instead of HDR.

If your smartphone is heating above 50°C, use a cooling stand or take breaks every 20-30 minutes. Overheating is one of the main reasons for FPS drawdowns on the Snapdragon 625.

💡

To monitor the temperature, install the CPU Monitor or AIDA64 app. If the temperature is above 60°C, immediately close the game and let the device cool down.

Frequent Mistakes and How to Avoid Them

When you turn off the acceleration of games, users often make mistakes that lead to new problems.

⚠️ Note: Do not use cache cleaning apps before playing. MIUI Automatically manages memory, and forced cleaning can lead to game crashes when textures are loaded.

• 🚫 Disable all optimizations: Some users on the engineering menu turn off all performance-related settings.This can cause a general system slowdown, GPU Optimization).
• 🔄 Frequent reboot: After changes to the engineering menu or through ADB It's enough to reboot a single reboot. Multiple reboots won't speed up the settings, they'll only make the flash memory wearier.
• 📱 Use of unofficial firmware: Castom firmware (such as LineageOS or Pixel Experience) may not support the correct work with games. If you encounter problems after firmware, return to the official MIUI.
