Accelerating games on Xiaomi: overclocking FPS, Game Turbo and hidden settings MIUI

If you own a Xiaomi, Redmi or POCO smartphone and notice that games on your device slow down, hang or give low FPS, do not rush to blame the iron. Modern models on Snapdragon 8 Gen 2 or Dimensity 9000+ chips are able to pull even the most demanding projects like Genshin Impact or Call of Duty Mobile - but only with the right settings. In this article, we will analyze what is the acceleration of games on Xiaomi, how the built-in Game Turbo mode works, what hidden MIUI functions will help to squeeze out the maximum performance, and why sometimes "overclocking" can damage your phone.

We warn you right away: the term “acceleration” in the context of Xiaomi is often misunderstood. This is not about physical overclocking of the processor (as on a PC), but about software optimization - disabling background processes, prioritizing resources for the game and fine-tuning graphics. For example, on Xiaomi 13 Ultra or POCO F5 Pro you can forced to run the game in a resolution of 2400×1080 instead of the standard 1600×720, but this will require manual manipulation of the developer settings. And on budget models like Redmi Note 12, even the correct activation of the Game Turbo can give an increase in FPS by 15-20%.

It's important to understand that not all acceleration methods are safe. Some Internet life hacks (like turning off the thermal throttle through ADB) can cause the battery to overheat and degrade. We've only collected proven methods that do not violate warranty or shorten the life of the device. But everything in order.

What is the Game Turbo on Xiaomi and how does it work?

Game Turbo is Xiaomi’s proprietary technology, which debuted back in 2018 on Black Shark, and later migrated to all flagship and mid-budget models.

• 🔄 Blocks background processes (suspends updates, syncs, and notifications to free up RAM and CPU).
• 🎮 Activates high performance mode (increases the clock frequency of the processor and graphics accelerator).
• 📶 Optimizes the network (prioritizes game traffic by reducing ping online).
• 🔋 Controls heating (limits the temperature of the chip to avoid trottling).

Starting with MIUI 12, Game Turbo is integrated into system settings and automatically starts when you open supported games (the list is determined by Xiaomi).However, on budget models like Redmi 10A or POCO M4 Pro, this mode can be reduced or completely absent.

1. Open Settings → Special features → Game Turbo
2. If there is no point, try to run any game (for example, PUBG Mobile) and swipe from the top right corner of the screen down - a floating menu with an icon should appear 🎮.

On models with Snapdragon 888 and later (Xiaomi 11/12/13 series, Black Shark 4/5), the Game Turbo can automatically adjust the screen resolution for the game, reducing the load on the GPU without losing visual quality. For example, in Honor of Kings or Free Fire, the system will choose the balance between performance and graphics based on the current temperature of the processor.

How to Enable Hidden Performance Mode on MIUI

Even if the Game Turbo works on your Xiaomi, its standard settings don't always have the maximum effect. There are additional switches hidden in the depths of MIUI that allow you to turn off heating restrictions, increase the FPS limit, and even force high-resolution games to run.

1. Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version. Enter the Mi Account password if required.
2. Set up hidden options: Return to Settings → Additionally. → For developers. Find and turn on: 🔧 Enforcement of use GPU-rendering (improves graphics, but can increase heating). ⚡ Limit background processes (exhibit "Without background processes"). 🔥 Disable thermothrottle control (caution! for testing only!).

On some models (such as the Xiaomi 12T Pro or POCO F4 GT), there is a separate Game Driver Settings section in the developer menu, where you can manually select the version of the graphics driver (such as the Adreno 730 for the Snapdragon 8 Gen 1) and even enable experimental support for the Vulkan API, which gives an increase in FPS in some games.

⚠️ Warning: Disable thermal throttling may cause overheating above 60°C and Auto Shutdown. Use this mode only for benchmarks and return settings back immediately!

Table: Compatibility of Accelerating Games with Xiaomi Models

Not all Xiaomi smartphones support full-scale game acceleration, and here is a table of up-to-date data for 2026 (for MIUI 14/15 firmware):

Note that even on flagships like the Xiaomi 13 Pro, real FPS depends on ambient temperature and battery power, for example, when the charge is below 20%, the system automatically reduces performance to avoid a sudden shutdown.

Top.-5 Applications to speed up games on Xiaomi (without root)

If standard MIUI tools are not enough, you can use third-party utilities. Importantly, we recommend only proven applications from Google Play that do not require root rights and do not violate Xiaomi policies.

1. GFX Tool (for) PUBG Mobile, Call of Duty, Free Fire): 🎯 Allows you to manually set permission, schedule and FPS. 🔧 Works through overlay (does not require root). ⚠️ On some models, it can cause a ban account (use at your own risk).
2. Game Booster 4x Faster: ⚡ Optimizes RAM and CPU single-tape. 📊 Shows temperature and loading of cores in real time.
3. L Speed (for experienced users): 🛠️ Configures the kernel parameters (requires knowledge!). 🔋 Helps reduce heat during long sessions.

💡

Before using the GFX Tool, back up your game settings through Google Play Games. Some servers (such as PUBG Mobile) may block your account for changing your graphics settings.

Important: Avoid apps like CPU Tuner or SetCPU, which require root access and can permanently de-warranty, and avoid using game mods, which violates the rules of most online projects.

Dangerous myths about speeding up games on Xiaomi

There are a lot of tips on the Internet to “disperse” Xiaomi smartphones, which are not only useless, but also harmful, and let’s take a look at the most common myths and explain why they should not be used:

• ❌ "Shutdown MIUI Optimization increases the level of FPS" In fact: This setting (Settings) → For developers → Turn off optimization MIUI) It only removes some of the animations of the system, but it doesn't affect the performance of the games.
• ❌ "Reality: The cache of games (like Genshin Impact) stores downloaded textures and data. Cleaning it will make the game download everything again, increasing the loading time.
• ❌ "Charging while playing speeds up the phone" It's dangerous: Connecting to charging increases heat and can cause trottling (automatic performance decline (120W+) Playing while charging is not recommended.

Another popular myth is that custom firmware installation increases FPS. Yes, some firmware like Pixel Experience or LineageOS can increase performance by removing unnecessary MIUI services.

• 🔄 You’ll lose Game Turbo and other branded optimizations.
• 🔋 Increased battery consumption (castom cores are often less optimized).
• 🛠️ The risk of “bricking” the phone when installed incorrectly.

How to Check Real FPS and Temperature During Play

To see if acceleration is effective, you need to measure the real numbers, and the tools that you can use are:

1. Built-in monitor MIUI: Run the game. Swipe your finger from the top right corner down to open the Game Turbo. 📊 — overlaid FPS, temperature CPU/GPU and loading RAM.
2. GameBench app (for advanced users): 📈 Fixing. FPS, subsidence and background temperature. 📊 Compares results with other devices.

ADB team for the dens

adb shell dumpsys gfxinfo com.pubg.krmobile (replace with your game ID)


adb shell cat /sys/class/thermal/thermal_zone*/temp

Normal indicators for modern games:

• FPS: 60+ (for Call of Duty Mobile), 90+ (for PUBG Mobile at high settings).
• CPU temperature: up to 50°C (normal), 50-60°C (warning), above 60°C (critical).
• GPU load: 80-95% (if lower, the game is limited in performance).

💡

If the FPS sags below 40 in lightweight games (such as Clash Royale), the problem is most likely in background processes or overheating, not in the “weak” hardware.
