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

Xiaomi smartphones are some of the most popular mobile gaming devices thanks to the powerful hardware and optimized MIUI firmware. But even on flagships like the Redmi K70 Pro or POCO F6 Pro, games can be slowed down due to background processes, overheating or incorrect settings. If you notice a drop in FPS in Genshin Impact, hanging in PUBG Mobile or long loading textures in Call of Duty: Mobile, this article will help to restore the smoothness of gameplay.

We tested all the methods on MIUI 14/15 devices (including HyperOS) and identified only those that really affect performance. There are no “magic” overclocking applications or dangerous firmware manipulations here, only proven system tweaks, hidden features and hardware optimizations. Importantly, on some models (for example, the Redmi Note 12 with a Snapdragon 4 Gen 2 processor), the FPS after optimization can increase by 20-30% due to the correct thermal throttle configuration.

1. Enable Game Turbo Mode and Hidden Settings

Game Turbo is Xiaomi's proprietary technology for speeding up games, but by default it doesn't work at full capacity.

  1. Open Settings → Special features → Game Turbo
  2. Turn the switch on in the “On” position and add the game to the list via “+”.
  3. Start the game and swipe from the right edge of the screen inside to open the Game Turbo panel.
  4. Click on the icon. ⚙️ («Settings") and activate: 🔥 Performance to maximum (disables clock frequency limitation) CPU/GPU). ⚡ Quick response (reduces delay in touching). 📶 Network Priority (reduces ping online). 🔇 No sound effects (saving resources).

On HyperOS models (such as Xiaomi 14), Game Turbo has a new mode called "Extreme Performance" that temporarily disables the battery's background optimization and unlocks the full CPU power, but can cause overheating. Use it only for short sessions.

💡

If the Game Turbo list does not include the game you want, add it manually through Other Games» → choose APK-file /storage/emulated/0/Android/data.

For advanced users, Game Turbo has a hidden menu to manually adjust temperature restrictions to open it:

adb shell am start -n com.miui.gameturbo/.ui.GameTurboDeepSettingsActivity

In this menu, you can increase the temperature threshold (for example, from 45 ° C to 50 ° C), but this is risky for the battery.

2. Background optimization: what to turn off before playing

Even on top-end smartphones, background processes can eat up to 30% of performance.

Close all applications through the “Recent” button

Disable Wi-Fi/mobile data for unnecessary applications in Settings → Connections → Data Use

Turn off syncing of Google Account and Mi Cloud

Remove widgets from the main screen (they consume RAM)

Disable MIUI Optimization in the Developer Settings (see Section 4)

-->

Pay special attention to autoboot. Many apps (e.g. Facebook, TikTok) are triggered when the screen is turned on and slow down games.

  1. Go to Settings → Applications → Autostart Management.
  2. Sort the list by Auto Start and disable everything except system services.
  3. For full control, install Greenify (root rights required).

For microSD-enabled devices like the Redmi Note 11, you can use an A2-class memory card to store games, which will not speed up loading, but will reduce the load on internal memory.

⚠️ Warning: Self-replacement of thermopastes or batteries is not warranty. On models with adhesive housing (for example, Xiaomi 12) to disassemble will require a hair dryer and a mediator.

FAQ: Frequent questions about speeding up games on Xiaomi

Can I overclock the processor on Xiaomi without root?
No, full overclocking on Snapdragon or MediaTek is only possible with an unlocked bootloader and custom core. However, the Game Turbo has a “Performance to Maximum” option that temporarily removes the clock speed restrictions without root rights.
Why did the game slow down after the MIUI update?
Newer versions of MIUI (especially MIUI 14+) add battery optimization (MIUI Battery Saver) back-end services that limit performance. Turn them off in Settings → Battery → Battery Mode → Performance.
How to check if the processor is trolling during the game?
Install the Throttling Test CPU from Play Market, and if you have throttled strings in the results, it's down to overheating, and you can use AIDA64 to monitor real-time temperature.
Do FPS Boosts from the Play Market Help?
No, apps like Game Booster 4x Faster or GFX Tool don't really give you any performance gains, they just clear the cache and turn off the background processes -- the same can be done manually (see section 2).
How to speed up the download of games with MicroSD?
Games on the memory card always load slower due to the limitations of the UHS-I interface. To speed up the load: Use a UHS-II card (for example, Samsung Pro Plus). Move only light games (for example, Among Us, Brawl Stars) to SD. In the developer settings, enable Force allow apps on external.
