How to increase FPS on Xiaomi: from basic settings to hidden MIUI chips

Low FPS in Xiaomi smartphone games is a common problem, especially on budget models like the Redmi Note 12 or POCO X5. Even the flagships of the Xiaomi 14 series sometimes “suck” due to aggressive energy optimization in MIUI. But the good news is that 90% of users can raise FPS by 20-40% without root rights, just by setting the system correctly.

In this article, only proven methods, from basic (background cleaning, performance modes) to advanced (GPU overclocking through ADB, disabling MIUI Optimization) We will discuss why Xiaomi with a Snapdragon 8 Gen 2 FPS processor in Genshin Impact can be lower than Samsung with the same chipset, and how to fix it. All instructions are relevant for MIUI 14/15 and Android 13/14.

1. Basic MIUI settings to boost FPS

Start with the obvious: MIUI by default limits performance to save battery power.These restrictions can be removed without risk to the phone.

The first thing to do is turn off background optimization for games. Go to Settings → Applications → Application Management → [select game] → Battery → No restrictions. This will prevent the game from automatically closing when it curtails. For the POCO F5 and other models with MediaTek Dimensity, it is also useful to enable Performance Mode in the battery settings.

• 🔧 Turn off Adaptive Brightness - it eats up to 10% resource GPU. Set a fixed brightness to the 70-80%.
• 🎮 Enable "Game Mode" in the notification curtain (or in Settings) → Special opportunities → It turns off notifications and optimizes the clock clock.
• 🔄 Reset your in-game graphics settings – sometimes they get lost after updates MIUI. For example, in Call of Duty Mobile go to Settings → Graphics → Reset to optimal.

⚠️ Attention: On Xiaomi 13T and other models with AMOLED-screen-include (>80%) It can cause the processor to throttle because of overheating. 60-70% balance FPS stability.

2. Hidden developer settings for overclocking the GPU

There are several parameters hidden in MIUI that directly affect FPS, and to activate them:

1. Go to Settings → About Phone → MIUI version and tap 7 times on this item until the notification “You became a developer” appears.
2. Go back to the main settings menu and open a new section for developers.

Now, find and change these parameters:

On Xiaomi 12S Ultra and other flagships, the refresh rate restriction option is also available – set it to a maximum value (for example, 120 Hz or 144 Hz).This synchronizes FPS with the screen frequency, reducing frame gaps.

💡

If after changes in the developer settings, the games began to slow down, reset the graphics driver settings through Settings → Applications → Application Management → [game] → Storage → Clear the cache.

3.Cooling Optimization: Why Xiaomi “Strikes” FPS When Heated

The main reason for the fall of FPS on Xiaomi is thermal throttling. Already at 43°C, the processor begins to reduce frequencies, and at 47°C, it forcibly limits the performance of the GPU, this is especially noticeable in heavy games like Genshin Impact or Honor of Kings.

Decisions:

• ❄️ Use a cooling case (e.g. Black Shark Cooling Backclip) 2 It lowers the temperature by 5-8°C, what gives +15-20% FPS.
• 🧊 Turn off charging while playing, fast charging heats up the battery, which causes throttling. If you want to play with charging, use a cable. USB 2.0 (slower heat).
• 🌡️ Install the app CPU Monitor (from Xiaomi GetApps) to monitor real-time temperature.Critical mark - 45°C.

⚠️ Attention: POCO F4 GT and other models with active cooling (built-in fan) do not block the vents with a cover. 15-20 play-off FPS on 50%.

4.Switching off MIUI Optimization: A Radical Way to Boost FPS

MIUI Optimization is a service that “optimizes” the system, but in practice often interferes with games, and disabling it can give you +25% FPS, but it requires caution.

Instructions via ADB (without root rights):

1. Download Platform Tools from the Android website.
2. Connect your phone to your PC, enable USB debugging in the developer settings.
3. Open the command line in the adb.exe folder and type: adb shell pm disable-user --user 0 com.miui.powerkeeper adb shell pm disable-user --user 0 com.miui.thermald
4. Reboot the phone.

Effect:

• 📈 FPS into PUBG Mobile is up from 40 before 55-60 on the Redmi Note 11 Pro+.
• 🔥 Processor temperature rises faster – watch for heating!
• ⚡ The Autonomous Work Time is reduced by 15-20%.

5. Overclocking the GPU through configuration files (for advanced ones)

On some Xiaomi models (e.g. Xiaomi) 12 pro POCO F3 GT) You can manually change the frequencies. GPU, file-edit /vendor/gpu/gpu_freq.conf. This requires root rights and can lead to unstable work!

Example configuration for the Adreno 730 (Snapdragon 8 Gen 1):

Minimum frequency (MHz)


min_gpu_clk=300




Maximum frequency (MHz)



max_gpu_clk=840




Thermothrottle threshold (°C)



thermal_throttle_temp=55

After the file changes:

1. Set the license 644 (rw-r-----).
2. Reboot the phone.
3. Check the stability in the 3DMark benchmark.

⚠️ Note: Xiaomi 13 Pro with Snapdragon 8 Gen 2 overclocking GPU A high of 980 MHz can cause graphic artifacts in games. The optimal value is 930 MHz.

💡

Disabling MIUI Optimization and overclocking the GPUs are the biggest increases in FPS, but they shorten battery life. Use these methods only for short-term gaming sessions.

6.Alternative firmware: when standard methods do not help

If you've tried everything, but the FPS is still low, consider switching to custom firmware.

Installation process:

1. Unlock the bootloader through the Mi Unlock Tool (requires a wait of 7-14 days).
2. Install TWRP Recovery for your model.
3. Sweep through firmware and GApps (if you need Google services).

Example of performance gains on Redmi K50 Gaming:

💡

Before you run your firmware, check the model compatibility on the XDA Developers forum. Some firmware (such as the POCO X3 Pro) requires additional patches to run the camera.

7 Hardware modifications: when software methods are exhausted

If you’re ready to go further, consider hardware improvements:

• 🔋 Replacement of thermopaste with Arctic MX-6 Or Thermal Grizzly Kryonaut, on Xiaomi Black Shark. 5 It lowers the temperature on 3-5°C, what gives +5-10 FPS.
• 🛠️ Installation of copper plate on the chipset (requires disassembly of the phone). POCO F2 Pro.
• 🔌 Use of external GPU through USB-C (For example, Razer Core X. Supported on Xiaomi 13 Ultra with Android 13+.

Cost and risk:

• Replacement of thermopaste: ~ 1500 rubles (independent) or 3000 rubles (in the service).
• Installation of copper plate: ~5000 RUB Risk: overheating of other components with improper installation.
