You run your favorite game on Xiaomi Redmi Note 12 or POCO X5 Pro, and instead of smooth gameplay you get slowdowns, FPS drawdowns and annoying lags? The problem is familiar to many owners of Xiaomi smartphones - even flagship models sometimes can not cope with modern games at maximum settings. But it is not always in the "weak" hardware: often to blame background MIUI processes, improper graphics settings or overheating of the processor.
In this article, we will discuss 10 proven ways to speed up games on any Xiaomi smartphone – from budget Redmi to top Xiaomi 14 Ultra.
- 🔧 Set up a performance mode in MIUI maximum FPS
- 📱 Optimize screen resolution and refresh rate
- 🔥 Prevent trottling (automatic power reduction) in overheating
- 🚀 Use hidden engineering menus to overclock GPU
All methods work without root rights (though some will require developer mode activation). Ready to turn your Xiaomi into a game monster?
1. Enable Performance Mode in MIUI Game Turbo
Xiaomi smartphones have a built-in Game Turbo tool, similar to Game Mode from other brands, but few people know that it hides a maximum performance mode that disables all the limitations of MIUI for games.
1. Open Settings → Special Features → Game Turbo (on some firmwares, the path may differ: Settings → Applications → Game Turbo).
2. Select the game you want to speed up (e.g. Call of Duty Mobile or Honor of Kings).
3. Go to Game Settings → Performance Mode and select “Maximum Performance”.
Activate the options:
- ⚡ Turn off automatic brightness reduction (prevents drawdowns) FPS light-shift)
- 🔇 Disable notifications (background processes eat up to 10% CPU)
- 📶 Network Priority (reduces ping in online gaming)
💡
If you're in your version MIUI No Maximum Performance, upgrade the Game Turbo via Google Play or install it APK from the official Xiaomi website.
Important: This mode increases the CPU heat by 15-20%, so use it only with the cooler on or in a cool room. On the Xiaomi 13T and later, there is a built-in cooling system Loop LiquidCool, which partially compensates for the heating.
2. Optimize screen resolution and refresh rate
Many games automatically choose the maximum resolution, but this is not always justified. For example, in Genshin Impact, the difference between 1080p and 720p on a 6.67 inch screen is almost invisible, but FPS can grow by 20-30%.
1. Go to the game settings and find the Graphics or Display section.
Set:
- 🎮 Permission: 1600×720 (Most games are enough)
- 🔄 Update frequency: 90 Hz or 120 Hz (if the screen supports)
- 🖼️ Quality of textures: Medium (high gives) +5% to the chart, but −15% FPS)
On smartphones Xiaomi with AMOLED-screens (e.g. Xiaomi) 12S Ultra can be additionally enabled DC Dimming in Settings → Display. It'll reduce the flickering of the backlight and reduce the load on the light. GPU 5-7%.
| Permission | FPS in PUBG Mobile | Heating the CPU | Battery consumption |
|---|---|---|---|
| 2400×1080 | 40–50 | 75–80°C | 18-20%/hour |
| 1920×1080 | 50–60 | 65–70°C | 15-17%/hour |
| 1600×720 | 60–70 | 55–60°C | 12-14%/hour |
| 1280×720 | 70–80 | 50–55°C | 10–12%/hour |
Note: Xiaomi Black Shark (Gamer smartphones brand) has an additional option “Magic Press” – it allows you to assign physical buttons on the case to control in games, which reduces input delays by 10-15 ms.
3. Disable background processes and optimize MIUI
MIUI is known for aggressively controlling background processes, but sometimes it plays against the user, such as auto-cleaning RAM can shut down a game at the most inopportune time.
☑️ Optimization MIUI play-off
1. Go to Settings → Battery and Performance → Battery Management.
2. Find your game in the list and select "No Limits".
3. Return to Settings → About Phone and 7 times click on the MIUI Version to activate Developer Mode.
4. Go to Settings → Additional → For developers and install:
- 🛑 Do not save actions (disables background screenshots)
- ⚡ Limitation of processes → Maximum 4 of the process
- 🔄 Windows animation and transition animation → Disconnected.
Warning: Disabling process restriction can increase battery consumption by 5-10%, but the game will be more stable. On Xiaomi with 8+ GB of RAM (for example, the POCO F5 Pro), this effect is less noticeable.
What if the game is still going down?
4.Use the engineering menu to overclock the GPU
On Xiaomi smartphones with Snapdragon processors (such as the Snapdragon 8 Gen 2 in the Xiaomi 13 Pro), you can manually increase the clock speed of the GPU through the engineering menu, which gives an increase in FPS by 10-20%, but requires caution.
1. Install the MTK Engineering Mode app (for MediaTek) or Qualcomm Treble Info (for Snapdragon) from Google Play.
2. Open the menu and go to the "GPU" or "Performance" section.
3. Find the parameters:
- 📈 GPU Governor → set up performance
- ⚡ Max GPU Frequency → Increase by 10-15% of the current value
Attention. ⚠️ Exceeding frequency GPU More than 20% can lead to artifacts on the screen or overheating. On a liquid-cooled Xiaomi (such as the Black Shark 5 Pro), the risk is less, but it is still not recommended to set maximum values.
To check the stability after overclocking, run 3DMark or GFXBench — if the tests are smooth, you can test in games. If you see green lanes or departures, return the settings to place.
5.Cooling: How to Prevent Trottling
The main reason for the FPS drawdown on Xiaomi is trottling (automatic power reduction when overheating). Even on flagships like Xiaomi 14, after 10-15 minutes of playing, the processor begins to suffocate, losing up to 30% of performance.
1. Cooler or fan: Use an external cooler (like Black Shark FunCooler Pro) or even a regular cooler USB-Fan, 10th temperature drop.°C gives +5–10% FPS.
Thermopaste: On older models (e.g. Redmi Note 9 Pro) you can replace the thermopaste yourself. The new paste (Arctic MX-6) reduces the temperature by 5-8 °C.
3 Cooling case: gel filler covers (e.g. from ZMI) take heat away from the processor.
4. MIUI settings: in Settings → Battery → Temperature control, disable “Overheating Performance Limitation” (not available on all models).
💡
The most efficient cooling method is a combination of an external cooler + a 70 percent reduction in screen brightness, which reduces heat by 15-20 percent without loss of visibility.
Attention. ⚠️ If the temperature of the processor exceeds 85°C, stop playing immediately! Prolonged running in this mode shortens battery life and can lead to chip detachment (especially on budget models with soldered processor).
6. Alternative methods: from firmware to iron
If all software methods are exhausted, and the game still slows down, consider radical solutions:
1. Custom firmware: Firmware like Pixel Experience or LineageOS lacks the “heavy” MIUI shell and gives +10-15% FPS.
Battery replacement: On older models (Redmi Note 8 Pro, POCO X3 NFC) A worn-out battery can limit performance. A new battery costs ~1500–2500 ₽.
3. GPU Driver Update: On some devices (such as Mali-G77 chips), you can manually update drivers via the ARM GPU Driver Update in Google Play.
4.Using cloud gaming: Services like Xbox Cloud Gaming or GeForce NOW allow you to play heavy projects (such as Cyberpunk 2077) on any Xiaomi by streaming a picture from the server.
Tip: Before installing custom firmware, check compatibility with your model on the XDA Developers forum. Wrong firmware can turn your phone into a "brick."
