Where to look for a game accelerator on Xiaomi: hidden settings and the best apps

Xiaomi smartphones have long been popular with gamers thanks to their powerful hardware and flexible settings. But even top-end models like the Redmi K70 Pro or Xiaomi 14 Ultra can slow down in modern games due to background processes or unoptimized settings. Here comes the game accelerator, an integrated or third-party tool that temporarily “overclocks” the system, disabling unnecessary services and allocating maximum resources to the game.

The problem is that Xiaomi’s proprietary accelerator is often hidden in the depths of MIUI or not at all in some regional firmware. And third-party apps from Google Play don’t always work correctly or require root rights. In this article, we’ll look at all the ways to find and activate a game accelerator on Xiaomi, from hidden MIUI features to proven third-party utilities that actually speed up Genshin Impact, PUBG Mobile or Call of Duty: Mobile.

Built-in game accelerator in MIUI: where to look and how to turn on

Since MIUI 12, Xiaomi has added a hidden Game Turbo to the firmware, an accelerator that automatically optimizes performance when games are launched. However, access to it varies by smartphone model and region. For example, on global versions of Redmi Note 12 Pro+ or POCO F5, this feature may be called Game Booster, and on Chinese firmware – (literally “game accelerator”).

To find the built-in accelerator:

• 🔍 Open the Settings. → Special facilities → Game Turbo: Some models may have different paths).
• 🎮 If there is no item, try searching for Game Turbo or Game Mode.
• 📱 On the old versions. MIUI (before MIUI 11) the accelerator could be called the Game Accelerator and be in Settings → Annexes → Game mode.

Important: On some models (for example, POCO X3 Pro) Game Turbo activates automatically when supported games are launched. To check this, open the game and swipe from the top edge of the screen down if a panel with a screen appears. FPS-The Turbo button and counter, so the function is already working.

Secret codes and engineering menu for activating the accelerator

If you don't have a visible accelerator item in your settings, you can try turning it on through an engineering menu or hidden commands, which doesn't work on all models, but it often helps unlock additional features.

Here are the proven ways:

• 📞 Enter the phone code in the Phone app: ##4636## From the menu that opens, select Battery Information and search for Game Mode or Performance Mode.
• 🔧 For models on Qualcomm Snapdragon (for example, POCO F4 GT) Try the code: ##2846579## Then go to ProjectMenu → Background Settings → Game Mode.
• 🛠️ On some devices with MediaTek (for example, Redmi Note 11 Pro)+) The code is running: ##36446337## After that, open Engineer Mode → Hardware Testing → Game Mode.

Critical: Do not change other options in the engineering menu if you do not know their purpose! This can lead to unstable operation of the smartphone or even a "brick" (breakdown of the firmware).

The Best Third-Party Game Accelerators for Xiaomi

If the built-in MIUI tools don’t add the FPS or are not on your model, third-party apps will come to the rescue, and we tested dozens of utilities and selected those that actually work on Xiaomi without root and do not load the system with advertising.

Among the listed Game Booster 4x Faster is the most versatile solution for most users. It does not require root and is compatible with budget models like Redmi 10A. However, for maximum performance in heavy games (for example, Genshin Impact at maximum settings), it is better to combine it with the GFX Tool.

💡

Before installing a third-party accelerator, check its Google Play ranking and user reviews with your Xiaomi model.Some apps may conflict with MIUI and cause lags.

How to check if the game accelerator is working

Install an app or activate Game Turbo, half the way, you have to make sure that the accelerator actually works and you get a performance boost.

• 📊 Use it. FPS-Enable it in the game settings (e.g. in the PUBG Mobile is done in Settings → Graphics → Counter. FPS). If after activation of the accelerator FPS grew 10-20%, So it works.
• 🔥 Check the temperature of the processor before and after the game starts using the app AIDA64 or CPU Monitor: If the accelerator is operating correctly, the heating shall not exceed 45-50°C (on liquid-cooled models such as Black Shark) 5 Pro - before 55°C).
• ⚡ Run a performance test in 3DMark Or Geekbench in Game benchmark mode. Compare the results to the accelerator turned off and on.

⚠️ Attention: If after activation of the accelerator, the game begins to "freeze" or fly out, then the application conflicts with the firmware. MIUI: Settings → Annexes → Application management → [play-off] → Battery → No restrictions.

Optimizing MIUI for maximum gaming performance

Even with the accelerator on, Xiaomi can “brake” due to background MIUI processes. To get the most out of your smartphone, follow these steps:

Disable application autoupdate |Remove unnecessary system applications (via ADB) |Activate performance mode in battery settings |Disable animations in developer |Enable forced use of GPU-->

Details on each item:

• 🔄 Turn off auto-update apps: Go to Google Play → Settings → Auto-update of applications → Never.Found updates eat up traffic and resources CPU.
• 🗑️ Remove unnecessary system applications: Using the adb shell pm uninstall command -k --user 0 com.miui.weather2 You can remove the standard weather (replace it). com.miui.weather2 For the list of safe packets to remove, see 4PDA.
• ⚡ Activate Performance Mode: In Settings → Battery → Select Performance Mode. On some models, this item is hidden — search by settings.

For advanced users, enable forced use of the GPU in the developer settings.

1. Activate Developer Mode (7 times click on the MIUI version in Settings → About Phone).
2. Go to Settings → Additional → For developers.
3. Find the Forced Use of the GPU and turn it on.

⚠️ Attention: Forced use GPU It can increase battery consumption by 15-20%. Use this mode only during games and after the session is over, turn off.

What to do if the accelerator is not working

Sometimes, even after all the manipulations, the game accelerator doesn't have a visible effect, and here are the most common causes and solutions.

If nothing works, try resetting MIUI to factory settings (don’t forget to make a backup!) Sometimes system lags arise from accumulated tails after numerous updates. Also check if there are viruses or mining bots on your smartphone – they can steal resources in the background.

💡

If your Xiaomi smartphone is older than 2020 (for example, Redmi Note 8 Pro or POCO X2), do not expect miracles from the accelerator. On a weak hardware (Snapdragon 720G or Helio G90T), the FPS increase will not exceed 5-10%, and the main effect will be optimized graphics in the game settings.

Alternative ways to speed up games on Xiaomi

If standard methods have failed, try these non-obvious techniques:

• 🔌 Use charging while playing: Many Xiaomi models automatically release performance restrictions when the charger is connected.
• 🌐 Connect to 5G or Wi-Fi 6: In online games like Free Fire or Fortnite, latency is often not due to hardware, but to the network. Use a router that supports Wi-Fi 6 (for example, Xiaomi). AX6000) mobile 5G.
• 🎧 Turn off Bluetooth headphones: Wireless headphones (even Xiaomi Buds 4 Pro) put extra strain on the processor. FPS use wired.

For flagship owners (Xiaomi 13T Pro, Redmi K60 Ultra), there is another life hack: kernel overclocking. With the Kernel Adiutor app (requires root), you can manually increase the clock speed of the GPU by 10-15%, but this will reduce battery life and increase heating. Use this method only on liquid-cooled devices!

⚠️ Attention: Acceleration through the core can lead to thermal throttling (automatic performance loss due to overheating).If the smartphone starts to "trottling" (drops sharply). FPS through 10-15 minutes of the game, return the kernel settings to the standard.
