Have you noticed that your favorite game on Xiaomi has started to slow down and the interface animation is twitching? The problem isn’t always with a “weak” processor – often the fault is the system settings, background processes or performance limitations that MIUI imposes “by default.” In this article, we’ll look at 10 proven ways to increase FPS (frames per second) on Xiaomi, Redmi, POCO and Black Shark smartphones – from basic tweaks to hidden features for gamers.
It's important to understand that FPS is not just about hardware, but also about how the system allocates resources. Even flagships like Xiaomi 14 Ultra or Black Shark 6 Pro can get frame drawdowns due to background updates, overheating or power saving restrictions. And on budget models (Redmi Note 12, POCO X5), the right settings sometimes increase up to 30-40% in games without overclocking the processor.
We won’t recommend “magic overclocking apps” (most of them are dummy or malware), instead focusing on official MIUI tools, hidden developer options, and hardware chips that Xiaomi doesn’t advertise. Ready? Let’s start with the simplest.
1. Enable Game Turbo mode and set it up correctly
Game Turbo is Xiaomi’s proprietary tool for optimizing games, but by default it works half-heartedly, and many users don’t even know that it can turn off FPS restriction, prioritize resources for the game, and block notifications that steal footage.
How to turn on and configure:
- 🎮 Open the Settings. → Special facilities → Game Turbo (on some models, path: Settings) → Annexes → Game Turbo).
- 🔧 Turn on the switch in the top corner and add your game to the list (click on it «+»).
- ⚡ Select the game from the list and activate: Performance Mode (or "Extreme Performance" on Black Shark). FPS (Block notifications and autobrightness (so as not to distract during the game).
- 📊 Click on “Graphics Settings” (if any) and select maximum resolution and frame rate (e.g. 120Hz for supported models).
⚠️ Note: On some models (Redmi 10, POCO M4 Pro) “Deactivate restriction” option FPS» In this case, move on to the following ways.
💡
If the game doesn’t appear in the Game Turbo list, try to run it manually and then add it through the “Recent” menu (swipe up → game icon → “Game Turbo”).
2. disable MIUI Optimization (hidden setting)
MIUI Optimization is a service that “optimizes” a system’s performance, but often it artificially limits performance to save battery power. FPS in games and smooth interface.
How to turn it off:
- Activate Developer Mode: Go to Settings → About Phone. Click 7 times on the MIUI Version (you will be notified "You are a developer").
Settings → Additional → For Developers
MIUI Optimization
Turn it off.
Reboot the phone.
⚠️ Attention: After disconnection MIUI Optimization can be small bugs in animations (like jigging when opening apps). This is normal — performance will increase, but visual smoothness may suffer a little. POCO F5 The new Redmi is a minimal effect.

3. Set the maximum screen refresh rate
Many users are unaware that their Xiaomi supports 90Hz or 120Hz, but by default runs at 60Hz to save battery.The screen refresh rate directly affects the perceived FPS - especially in dynamic games (PUBG Mobile, Call of Duty, Genshin Impact).
How to turn on:
- 📱 Go to Settings. → Display.
- 🔍 Find the screen refresh rate (or “Adaptive Refresh Rate” option on new models).
- 🎯 Choose 120Hz (or maximum value available). If you don't have an option, your model only supports 60Hz.
Some devices (POCO X3 Pro, Redmi K50) have an adaptive frequency that automatically switches between 60Hz and 120Hz. For maximum FPS, turn off adaptability and lock the value at maximum.
What if you don't have a screen frequency option? Some models (like the Redmi 9) have the maximum frequency hidden.
4. Clear background processes and turn off autoboot
Background apps are the main eater of RAM and CPU resources. Even if you don't see them in multitasking, they can steal up to 20-30% of performance, reducing FPS in games, especially messengers (Telegram, WhatsApp), social networks (TikTok, Instagram) and system services (Mi Cloud, Google Play Services).
How to optimize:
- 🧹 Manual Cleaning: Press the Home button (or swipe up and hold), then accumulate all unnecessary apps up to close.
- ⚙️ Disabling Autoboot: Go to Settings → Annexes → App management. Select an app (e.g. Facebook) → Auto-start → Repeat for all unnecessary programs.
- 🔄 Background activity restriction: In the same app settings, find Battery Use and select “Limit background activity».
⚠️ Warning: Do not disable autoboot for system applications (e.g. com.miui.securitycenter). MIUI. Also, don’t touch Google Play Services – without them, many functions will stop working.

5.Use performance and cooling modes
Xiaomi hides several hardware modes that can force performance through increased power consumption and heat, features that are particularly useful for gaming smartphones (Black Shark, POCO F-series), but also work on regular Redmi.
Where to find:
- 🔋 Performance mode: Go to Settings → Battery and performance → Modes. Select Performance or Game Mode (on Black Shark - "Shark Space»).
- ❄️ Refrigeration: On some models (POCO F4 GT, Redmi K60) There's an option called "Liquid Cooling" or "Turbo Cooling." 10-15 minutes before the game to reduce trottling (automatically reducing the frequency of the processor when overheating).
Black Shark owners can use a physical "Shark Space" switch to activate maximum performance and disable all restrictions. Other models have the same effect of turning on Game Turbo + Performance mode.
| Xiaomi model | Available performance modes | Max. increase in FPS (according to tests) |
|---|---|---|
| Black Shark 5 Pro | Shark Space, Liquid Cooling 5.0 | Up to 40% in Genshin Impact |
| POCO F5 | Game Turbo, Turbo Cooling | Up to 25% in Call of Duty Mobile |
| Redmi Note 12 Pro+ | Performance mode, 120Hz | Up to 15% in PUBG Mobile |
| Xiaomi 13T | Adaptive Performance, Cryo-velvet Cooling | Up to 30% in Honor of Kings |
6. Optimize the graphics settings in games
Many games automatically choose graphical settings based on the phone model, but often understate the quality to "safeguard" Manually you can boost the FPS by sacrificing some visuals (such as shadows or texture resolution).
How to set up:
- 🎮 In the game itself, find the “Graphics” or “Quality settings” section».
- 🔧 Set: Mode FPS: «High" or "Ultra" (if any) Permission: HD instead of Ultra HD (Effects: Turn off dynamic shadows, motion blur and depth of field. Anti-aliasing: Set on 2x Or shut it down completely.
- 📱 For PUBG Mobile, Call of Duty and Genshin Impact GFX Tools (developer rights required) These apps allow you to unlock hidden graphics settings.
⚠️ Note: In Genshin Impact, forced promotion FPS through GFX Tools can lead to a ban of the account (game detects modified settings!
💡
The most effective way to increase FPS in games is to lower the render resolution. For example, in Call of Duty Mobile, switching from Very High to Medium gives you an increase of up to 20 frames / second on the Redmi Note 11.
7. Update firmware and GPU drivers
Often low FPS is due to outdated GPU drivers or bugs in firmware. Xiaomi regularly releases updates that optimize performance for popular games, but many users ignore these updates.
How to update:
- 🔄 Go to Settings. → The phone. → Updating the system.
- 📥 Click on “Check Updates” and install the latest version. MIUI.
- 🎯 For POCO Check for separate updates for Game Space or Shark Space on Google Play.
If the update didn’t help, try resetting the graphics driver settings:
- Activate Developer Mode (see Section 2).
- Go to Settings → Additional → For developers.
- Find the GPU Driver Reset option (or GPU Driver Version) and select Update.
- Reboot the phone.
⚠️ Note: On some models (Redmi) 9A, POCO M3) driver-reset GPU If you have stripes or flickering after the reboot, return the standard settings to the same menu.
8.Check the phone for overheating and trottling
If your Xiaomi heats up above 45°C, the processor automatically reduces the frequency (trottling), which leads to a drop in FPS. This is especially true for smartphones on Snapdragon 8 Gen 1/2 (Xiaomi 12 Pro, Black Shark 5), which are warmed stronger than others.
How to deal with overheating:
- 🌡️ Install a temperature monitoring app (for example, CPU Throttling Test).
- ❄️ If the temperature is higher 50°C: Remove the case (especially silicone). Use a cooling stand or fan. Close all background applications. Lower the screen brightness to 50-70%.
- 🔧 On liquid-cooled models (POCO F4 GT, Redmi K50 Gaming: Turn Turbo Cooling Mode on Game Turbo.
For extreme cases (such as streaming games), you can use external cooling, such as Black Shark Funcoler, which tests reduce the temperature by 8-12 ° C, which prevents trottling.
