How to increase Xiaomi’s performance in games: from overclocking to hidden settings MIUI

Xiaomi smartphones have long established themselves as one of the best devices for mobile gaming thanks to powerful Snapdragon and Dimensity processors, high-frequency screens and optimized firmware. MIUI. However, even flagship models like Xiaomi 14 Ultra or POCO F6 Pro eventually begin to “brake” in modern games such as Genshin Impact, Call of Duty Mobile or Honor of Kings. the reasons lie not only in the “iron”, but also in software limitations, overheating, background processes.

In this article, we will discuss 10 proven ways to increase the FPS, Reduce lags and make the most of your Xiaomi – from basic settings MIUI pre-advanced GPU All methods have been tested on current models in 2022-2026 and do not require root rights (except for one exception).+ FPS In games, it's a justified sacrifice.

1. Activation of the Game Turbo mode and hidden settings MIUI

Firmware MIUI It has a built-in Game Turbo, a tool that automatically optimizes performance during games, but by default it doesn't work at full capacity:

• 🔧 Open the Settings. → Special facilities → Game Turbo.
• 🎮 Turn on the switch and add the game to the “Game Management” list».
• ⚡ Activate options: “Improving performance”, “Disable autobrightness” and “Block notifications».
• 🔍 Go to “Additional Settings” (three dots in the upper right corner) and turn on «GPU-Overclocking (not available on all models).

On models POCO Redmi with Snapdragon processors 8 Gen 2/3 Game Turbo has a "Extreme Performance" mode hidden to activate it:

1. Launch the game through Game Turbo.
2. Swipe down the notification panel and tap on the Lightning icon (will appear after the game launches).
3. Select Extreme – this will disable the restrictions on TDP (heat pack) and disperse GPU 10-15%.

💡

If your model doesn’t have an “Extreme Performance” option, try updating. MIUI Up to the latest version or install Global ROM — In Chinese firmware, this mode is often disabled.

2. Optimization of background processes and cleaning of RAM

MIUI It's known for being gluttonous to RAM, and even on devices with 12-16GB of RAM, it can leave dozens of unnecessary processes behind that steal resources from games:

• 🧹 Install “RAM Cleanup” on the machine: Settings → Annexes → Cleanup → Auto Clean (select "Aggressive Mode»).
• 🚫 Turn off auto-run of unnecessary apps: Settings → Annexes → Auto-Start Control (disable everything except instant messengers and system services).
• 🔄 Enable “Performance Mode” in Settings → Battery → Power regimens.
• 📱 Use the "Light Mode" for MIUI: Settings → Screen. → Display mode → Light (reduces the load on the GPU).

For advanced users: in MIUI 14+ There's a hidden function called Deep Clean, which removes the cache of system applications. ADB:

adb shell pm trim-caches 1000

This command frees up to 1-2 GB of memory, but requires a connection to a PC.

3.Acceleration GPU and CPU through the engineering menu (without root)

On most Xiaomi smartphones with Qualcomm processors (Snapdragon) 888/8 Gen 1/2/3) You can manually increase the clock frequency. GPU and CPU It's an engineering menu. It gives you an increase in the 10–20 FPS in games, but increases the heat.

Instructions:

1. Open the Phone app and enter the code ##4636##.
2. Go to the tab "Battery Information".
3. Slip on the Test Menu (may require a few taps).
4. Choose «GPU Rendering and install "Force" GPU rendering in the "On" position».
5. Come back and come in «CPU» — here you can increase the maximum frequency by 5-10% (for example, from 3.0 GHz to 3.2 GHz).

Warning: Do not increase the frequency by more than 10% - this can lead to hardware damage to the chip.

💡

Overclocking through the engineering menu is reset after restarting. To keep the changes, use the app «CPU Tuner" (requires" ADB-access).

4.Cooling: How to Avoid Trottling in Games

The main cause of the fall FPS Xiaomi overheats. It's over 85.°C processor automatically reduces frequencies (thermal throttling), which leads to lags:

• ❄️ Use a cooling case (e.g. Black Shark Cooling Backplate) – reduces the temperature by 5-10°C.
• 🌬️ Play in a ventilated room or near a fan (more effective than it seems!).
• 🔋 Remove the case – even thin silicone increases heating by 3-5°C.
• 🛠️ Replace the thermopaste (relevant for models over 2 years old). Xiaomi often uses cheap paste that dries out.

For emergency cooling during the game:

1. Put the smartphone on a metal stand (takes away heat).
2. Reduce the brightness of the screen to 50-60% – this reduces the load on the screen. GPU.
3. Turn on "Airplane Mode" on 10 seconds to turn off the modules 5G/Wi-Fi, warmer.

⚠️ Note: If your Xiaomi regularly heats up above 90°C in games, it's a sign of a thermal interface malfunction or damage to the radiator.

5. Graphics settings in games: balance between FPS quality

Many games automatically select the graphics settings based on the device model, but often understate the settings. +15–30 FPS without loss of visual quality.

Recommended settings for popular games:

For Unreal Engine games 4/5 (For example, Fortnite, Diablo Immortal) enable graphics in the settings:

• 🔄 «V-Sync» → Off. (reduces input lag).
• 🎨 «Anti-Aliasing» → FXAA or TAA (less resource-intensive than MSAA).
• 🌿 «Vegetation» → Low (heavy loading) GPU).

6. Advanced stunts: ADB-commands and modifications

For users willing to go beyond standard settings, there are a few hidden commands that greatly improve performance. ADB (debugging USB).

List of the most effective teams:

Disables animations (accelerates the launch of games)


adb shell settings put global window_animation_scale 0




adb shell settings put global transition_animation_scale 0




adb shell settings put global animator_duration_scale 0




Increases the limit of background processes (prevents game download from memory)



adb shell settings put global bg_process_limit 10




Unlocks hidden GPU settings (Snapdragon only)



adb shell setprop debug.gpu.force_msaa 4x




adb shell setprop debug.egl.hw 1




Turns off thermal restriction (Dangerous! Test only)



adb shell setprop persist.thermal.engine off

For the application of the commands:

1. Download Platform Tools from Google.
2. Turn on "Debugging by" USB» In Settings → The phone. → Version. MIUI (Tap 7 times, then go back to Settings → Additionally. → For developers).
3. Connect your phone to your PC and execute commands in CMD.

⚠️ Warning: persist.thermal.engine off command disables all thermal restrictions.This can cause overheating of over 100°C and CPU damage. Use only for benchmarks!

To constantly apply these settings without a PC, use the application «ADB AppControl (requires one connection to a computer to log in).

7.Alternative firmware and cores for maximum performance

If standard methods don't work, consider installing custom firmware or a modified kernel, which requires unlocking the bootloader and root rights, but gives you:

• 🚀 Increase FPS 20-40% with optimized drivers.
• 🔥 Full control of frequencies CPU/GPU.
• 🛡️ Absence of background processes MIUI.

The best firmware for gaming on Xiaomi:

For custom firmware installation:

1. Unlock the bootloader through the Mi Unlock Tool (waiting 7-14 days).
2. Install TWRP Recovery for your model.
3. Sweep through firmware and GApps (if you need Google services).
4. To overclock, install the “FrancoKernel” or “Kirisakura” core.

💡

Custom firmware is warranty-free and can cause the device to break. TWRP!

8 Hardware upgrades: what can be improved physically

If the software methods are exhausted, hardware upgrades remain, and some Xiaomi components can be replaced or improved on their own:

• 🔋 Battery: Over time, the capacity drops and the phone begins to limit performance. Replacement with a new one (original or green). MI) return 10-15% FPS.
• 🖥️ Thermopaste: On models over 2 years old, it dries. Replacement with Arctic MX-6 Thermal Grizzly Kryonaut reduces temperature by 5-15°C.
• 📶 Antenna module: On POCO F3/F4 redmi K40/K50 weak-signal 5G/Wi-Fi Heat increases the module. Replacement with Qualcomm QTM525 solves the problem.
• 💾 On budget models (Redmi Note) 11/12) slow-set UFS 2.1. Replacement UFS 3.1 (If supported, it speeds up the loading of games on 30–40%.

To replace components, we recommend contacting service centers with experience with Xiaomi.

On Xiaomi models 12S Ultra and 13 Pro can be installed externally GPU through USB-C (This will give an increase of 200-300% in games, but requires additional power and costs from 50 000 rubles.
