How to increase productivity in games on Xiaomi: from MIUI settings to overclocking iron

Xiaomi, Redmi and POCO have long been known to have great price-performance ratios, but even flagship models sometimes slow down in modern games. The reasons are not only hardware limitations, but also software clamps from MIUI, a proprietary shell that actively saves resources for battery life. In this guide, we will discuss 12 working methods to squeeze the maximum FPS from your Xiaomi without resorting to risky manipulations like unlocking the bootloader.

It’s important to understand that performance in games depends on three key factors – the processor (its clock speed and architecture), the graphics accelerator (Adreno/Mali), and RAM (read/write speed). At Xiaomi, all these components are controlled not only by hardware, but also by software: from the Android core to proprietary MIUI algorithms. We’ll start with secure ways and gradually move to more radical ones so that you can choose the optimal balance between performance and stability.

1. Disabling background optimization MIUI

By default, MIUI aggressively restricts background processes to save battery life, which causes the game to suddenly "suppress" due to a lack of resources, and the first thing to do is to turn off auto-optimization for gaming applications.

Go to Settings → Applications → App Management, find your game (like Genshin Impact or Call of Duty Mobile) and follow these steps:

• 🔄 Turn off the Battery Savings (switch at the top).
• 📱 Allow auto-start (Install "Auto-start»).
• 🚫 Stop optimizing. MIUI (tab "Battery optimization» → Choose "No restrictions»).
• 🔒 Block the application in the multitasking menu (swipe up) → pinch the game icon → «Block it»).

These settings will prevent the system from suddenly killing the game, but they can slightly increase battery consumption. If you play from charging, this minus is uncritical.

💡

After the changes, restart the smartphone - this will reset the MIUI cache and apply the settings correctly.

2. Activation of Game Turbo mode

Xiaomi is building a dedicated game accelerator called the Game Turbo into MIUI that optimizes resource allocation, blocks notifications, and even allows you to fine-tune the performance for each game separately.

To include the full potential of the Game Turbo:

1. Open Settings → Special features → Game Turbo
2. Activate the main switch at the top.
3. Start the game, then swipe from the top right corner of the screen down to open the Game Turbo panel.
4. Click on the icon. ⚙️ and choose: 🎮 Performance mode → «Extremely extreme». 📊 Monitor FPS → Turn on to track the framerate. 🔇 Blocking notifications → activate for all applications. 🔋 Optimizing the battery → Turn it off (if you play off the network).

Some models (such as the POCO F4 GT or Black Shark 5) have additional options in the Game Turbo, such as overclocking the GPU or forced use of 120 Hz. These are worth testing, but remember: prolonged use can lead to overheating.

3. Customization of graphical parameters in games

Many mobile games automatically choose their graphics settings based on the smartphone model, but these algorithms often understate the settings to avoid overheating, and manually increasing the detail or resolution, you can get a more stable FPS.

Here’s what to change in the graphics settings (for example, popular games):

Important: After changing the settings, restart the game to take effect, and also monitor the temperature of the device - if the smartphone heats up above 45 ° C, reduce the detail.

4. Cleaning the system and optimizing memory

Over time, MIUI becomes clogged with cache, temporary files and fragmented data, leading to performance drawdowns. Regular cleaning will help bring back the FPS.

Follow the following steps:

Delete the cache of games in Settings → Applications → [Game] → Memory → Clear the cache

Disable unnecessary background applications in Settings → Applications → Application Management → Background processes

Perform a deep cleaning through Security → Cleaning (use “Deep Cleaning”)

Reboot the device (this resets the core cache and releases RAM)

-->

For more in-depth optimization, you can use the Memory section in the security settings:

• 🧹 Cleanup RAM: Click on “Clean” in the Memory section (but don’t overuse – frequent cleaning can slow down your work).
• 🗑️ Waste removal: Use the built-in Cleanup tool with the “Deep Cleanup” tick».
• 🔄 Defragmentation: in some versions MIUI Option “Optimize” is available in the “Memory” section».

Critical: If you have less than 20% of the space available on your internal drive, the game will be slowed down due to lack of cache space and temporary files.

5.Using hidden engineering menus

Xiaomi hides from users a few engineering menus where you can fine-tune the work of the processor, GPU and memory. These settings are not officially dokument, so change them at your own risk.

The most useful teams:

• 📡 Network and performance test: ##4636## In the menu "Battery Information" you can see the real use CPU/GPU.
• ⚙️ Settings GPU (Not all models work: ##36446337## Here you can force OpenGL on. ES 3.2 or Vulkan for gaming.
• 🔥 Dispersal CPU/GPU (Only for advanced users!): ##7674387## In some firmware allows you to change the clock frequency of the cores.

Warning: Changing the settings in the engineering menus can lead to unstable operation, overheating or even a device blink. Before experimenting, back up through Settings → System → Backup.

💡

Engineering menus are designed for testing and debugging. Don't change the settings if you don't understand their purpose!

Installation of a custom core or firmware

If standard methods don't produce the desired FPS boost, the radical way is to install a custom core or firmware, which requires unlocking the bootloader, which resets all the data and can be insecure.

The most popular solutions for gamers:

• 🔧 Perseus or FrancoKernel: Optimized for performance, support overclocking GPU undervolting (reducing voltage to reduce heating).
• 📱 Pixel Experience or LineageOS: no “clamps» MIUI, give +10–15% FPS play.
• 🎮 Modified Game Turbo: Some custom firmware (e.g. Xiaomi.eu) includes advanced gaming settings.

Installation process:

1. Unlock the bootloader through the official Xiaomi tool.
2. Install custom recovery (TWRP or OrangeFox).
3. Flush the kernel or firmware through recovery.
4. Configure performance options (e.g. in Kernel Audiutor).

⚠️ Warning: Unofficial firmware may contain vulnerabilities or unstable drivers. Check forum reviews before installing 4PDA XDA-Developers for your model.

7 External accessories to improve productivity

If software methods are exhausted, you can improve the game experience with external devices, they will not increase the FPS directly, but will reduce the load on the smartphone and make the gameplay more comfortable.

Top.-5 accessories for gamers on Xiaomi:

• 🎮 Xiaomi Game Controller or RedMagic Mobile Gaming Trigger: Reduces the load on the touch screen, reducing the lags.

For example, tests show that using a cooler on a POCO F3 (Snapdragon 870) allows you to hold the maximum frequencies of the GPU for 15-20 minutes longer, which gives +3-5 FPS in Genshin Impact.

8.Alternative methods: from cooling to upgrade

If none of the above methods helped, there are non-standard solutions:

• 🧊 Refrigeration: Put your smartphone in a bag and cool it to 10-15°C for 5-10 minutes (no longer!) This will temporarily remove the trottling. ⚠️ Warning: Don't put the device near food or liquids! condensation can damage electronics.
• 🔄 Reset to factory settings: sometimes a "clean" system gives +10-15% productivity due to the removal of background debris.
• 🔧 Replace thermopaste: on older models (Redmi Note 8 Pro, POCO F1) Dry paste causes overheating. MX-4 Or Kryonaut can bring back the old FPS.
• 📱 Upgrade to the new model: if your smartphone is older than 2020, even the Snapdragon 865 may not be able to cope with modern games. K60 Pro (Snapdragon 8 Gen 2) or Black Shark 6.

Last tip: keep an eye out for MIUI updates. Newer versions often optimize GPU drivers. For example, MIUI 14 for the Redmi K50 Ultra added support for Vulkan 1.3, which gave +8% FPS in Honor of Kings.

💡

The greatest increase in performance is provided by a combination of methods: system cleaning + Game Turbo + cooling + manual graphics adjustment.
