How to speed up your game on Xiaomi: a complete guide to optimization FPS and productivity

Games on Xiaomi smartphones can slow down even on flagship models – lags, drawdowns FPS And the loading of levels is a bad thing for the gameplay experience, and it's not just the weak hardware that's the reason, but the wrong settings are more often the fault. MIUI, background processes or performance limitations that the system imposes by default.This article will help you figure out how to make the most of your Redmi, POCO Black Shark – from basic tweaks to hidden features for advanced users.

We tested all methods on current firmware MIUI 14/15 HyperOS, so the instructions are suitable for devices 2020–2026 Important: Some of the ways require unlocking the bootloader or root rights, which we've highlighted separately and warned you about the risks. If you're a beginner, start with safe steps. 1–3), A experienced users will find here and advanced techniques (sections) 4–6).

1. MIUI Optimization for Games: Hidden Performance Settings

System system MIUI The default is performance limits to save battery life. For gaming, these restrictions need to be removed. Let's start with basic settings that don't require administrator rights:

• 🔧 Turn off “charge savings” in games: go to Settings → Battery and productivity → Saving charge and adding the game to exceptions, this will prevent the processor clock speed from decreasing.
• 🎮 Activate “Game Mode”: in Settings → Special facilities → Game mode enable option and set performance priority for specific applications.
• 📱 Set a high level of performance: in Settings → The phone. → Version. MIUI (tap 7 times to unlock Developer Settings, then to Developer Settings → Limitation of background processes select "Without restrictions».

On HyperOS devices (e.g. Xiaomi 14 or Redmi) K70) The path to settings may be different. If you don't find "Game Mode," try an alternative path: Settings → Annexes → Application management → [Choose a game] → Battery → No restrictions.

💡

In some models (for example, POCO F5) In Game Mode, there's a hidden option called Extreme Performance. To enable it, hold the Game Mode button in the notification curtain for 3 seconds.

After applying these settings, launch the game and check. FPS using the GameBench utility or the built-in counter (if any in the game graphics settings), the difference can be as much as 15-20% compared to the standard settings.

System Cleanup: What to Remove to Keep Games from Slowing Down

Background, cache, and unnecessary applications steal resources from games, and cleaning up is a must before any optimization, starting with the simplest:

• 🧹 Clear the cache of games and systems: go to Settings → Warehouse → Clean and select "Deep Clean." Pay special attention to the folder. /Android/obb/ — It contains heavy game files (sometimes weighing up to a maximum of two years). 5–10 GB!).
• 🚫 Remove or freeze unnecessary apps: Use Settings → Annexes → Application management to disable pre-installed services (e.g. Mi Video, Mi Music, GetApps) will require root rights to completely remove system applications.
• 🔄 Turn off auto-update apps: on Google Play → Settings → Auto-Update apps select "Never." Updates in the background eat up traffic and processor.

For advanced cleaning, use the utility SD Maid (requires root) or Files by Google (works without administrator rights:

• /data/log/ — Logs of the system (can be deleted)
• /Android/data/ — Cache games (clean selectively so as not to reset progress)
• /MIUI/backup/ — backup MIUI (usually not)

After cleaning, restart the device and check the performance in the game. FPS It still sits down, move on to the next section.

3. Graphic customization: Balance between quality and performance

Many games (e.g. Genshin Impact, Call of Duty: Mobile, PUBG Mobile allows you to manually adjust graphics settings. Optimal settings depend on the model of the smartphone:

For games that support volcano rendering (such as Fortnite) select API Vulkan instead of OpenGL ES It's in the settings of the graphics. FPS 10-15%, but requires testing – Vulkan is unstable on some devices.

If the game does not allow you to manually select graphics settings, use the utility GFX Tool (for) PUBG Mobile) or Game Guardian (requires root) these tools allow you to unlock hidden options, such as 60. FPS on weak devices or Ultra HD-texture.

💡

On devices with AMOLED-With screens (such as Xiaomi 13 Ultra), turning off Adaptive Brightness in games can save up to 15% of battery power without losing performance.

4.Acceleration GPU and CPU: risks and opportunities

Advanced users can overclock the graphics processor (GPU) and central processing unit (CPU) ramp up FPS. This method requires an unlocked bootloader and root rights, and carries risks of overheating and shortening the life of the chip:

1. Install a kernel with overclocking support: for example, Kirisakura Kernel for Snapdragon 8 Gen 1/2 Perseus Kernel for Dimensity 9000. The cores are downloading from the forum XDA Developers.
2. Use the overclocking app: Kernel Auditor or EX Kernel Manager allows you to increase the clock frequency GPU For example, for the Adreno 730 (in the Snapdragon 8 Gen 1), the default frequency is 818 MHz, and after overclocking you can set 900-950 MHz.
3. Set up governor: in the same apps, choose performance instead of ondemand or balanced for CPU. This will make the processor work at the maximum frequency constantly.

Warning: Acceleration increases heat output. Without proper cooling (such as a cooler or a gaming case), the device will trott (reduce performance due to overheating). AIDA64 or CPU Monitor.

Install custom recovery (TWRP)

Make a backup copy. EFS-section

Check the temperature. CPU in simple (should be) < 40°C)

Download a kernel compatible with your model

Prepare a cooler or cooling stand-->

Example of configuration for POCO F4 GT (Snapdragon 8 Gen 1):

GPU: Adreno 730 @ 920 MHz (+12%)


CPU: 1x Cortex-X2 @ 3.05GHz (default 3.0GHz)




Governor: performance




Thermal: Disable the restriction at 45°C

💡

If after overclocking the game begins to “fly out”, try to reduce the frequency. GPU 50–100 MHz is often more important than the additional 2-3 FPS.

5.Cooling: How to Prevent Trottling

Trottling (decreased performance due to overheating) is the main cause of lags in long gaming sessions. Even Xiaomi's flagship smartphones warm up if not properly cooled. Here's what you can do:

• ❄️ Use a gaming cooler, like Black Shark FunCooler Pro or Razer Phone Cooler, which reduces the temperature by 5-10.°C, which prevents drawdowns FPS.
• 🧊 Stick heat pad: a thin copper or graphite pad between the processor and the back cover improves heat sink. Suitable for models with a metal body (Black Shark) 4/5).
• 🔋 Remove the case while playing: even a thin silicone case worsens heat transfer. Use uncoated glass on the sides to protect the screen.
• 🌡️ Limit battery power to 80%: in Settings → Battery → Battery mode select "Optimized Charge." Battery overheating enhances trottling.

Use the application to check the temperature CPU Throttling Test if the temperature is CPU more than 70°C, activated by forced productivity decline:

1. Close all background applications.
2. Reduce the brightness of the screen to 50%.
3. Used mode (if the game is offline).

6.Alternative firmware for maximum performance

Stock firmware MIUI Custom firmware (e.g. LineageOS, Pixel Experience or CrDroid) is offered:

• 🚀 Less background processes (no unnecessary Xiaomi services).
• 🎛️ More flexible performance settings (e.g. overclocking) GPU rootless).
• 🔄 More recent versions of Android (e.g. Android 14 instead of Android 12 on older devices).

For gamers, the best choice is to have either CrDroid or Havoc-OS with the Kiriskura kernel.

1. Unlock the bootloader (fastboot oem unlock).
2. Installations TWRP Or OrangeFox Recovery.
3. Formatting the data section (erases all data!).

Example of firmware for Redmi K50 Gaming:

• Firmware: CrDroid 9.x (Android 13)
• Core: Kiriskura 4.10 (with overclocking support) GPU up to 950 MHz)
• Additionally, Magisk for optimization modules (e.g. Game Optimizer)

💡

Castom firmware may deprive you of an official warranty. Before installing, check compatibility with your model on the forum XDA.

7. Network Optimization: How to Reduce Ping and Lag Online

In online games (like Free Fire or Call of Duty: Mobile), high ping or batch losses ruin the experience.

• 📶 Use it. 5G Wi-Fi: In Settings → Wi-Fi → Additionally, select the 5 GHz range (less interference than 2.4 GHz).
• 🔌 Connect by cable: using an adapter USB-C to Ethernet (e.g, UGREEN 10055 can be pinged < 10ms.
• 🌍 Select the nearest server: in the game settings, specify the region with the minimum ping (check through Ping & DNS).
• 🛡️ Turn it off. VPN: even "quickly» VPN Increase ping by 30-50 ms.

For advanced users:

• Change. DNS at 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) in Settings → Wi-Fi → Change the network → DNS.
• Enable Developer Mode and Activate Turn Off the Buffer TCP (Developer settings → Networks. → Buffering TCP).

If the game is supported LAN-Mode (e.g. Minecraft or Among Us), create a local area network via Wi-Fi Direct or hotspot for minimal latency.

8 Hardware modifications: what really helps

If software methods fail, consider hardware improvements. Importantly, most modifications require disassembly of the device and can void the warranty.

The most effective modification is to replace the thermopaste. POCO F3 (Snapdragon 870 - Replacing factory paste with Arctic MX-6 I've got my temperature down from 85.°C to 68°C in Genshin Impact, which eliminated drawdowns FPS 50 to 60 frames.

💡

If you are not sure about your skills, contact the service. The cost of replacing the thermopaste in the workshop is about 1000-1500 rubles, but it is cheaper than repairing after a failed disassembly.

For devices with external support GPU (For example, Black Shark 5 Pro can be connected to Razer Kishi or Backbone One, but the performance will only be increased in games with support for controllers (for example, Diablo Immortal).
