How to enable 120 FPS in games on Xiaomi: a guide for Redmi, POCO and Black Shark

Do you want to get the most out of your Xiaomi and get the coveted 120 frames per second in mobile games? That’s real — but only if you configure the hardware, the software and the games themselves. In this article, we’ll break down all the working ways to overclock FPS on Redmi, POCO and Black Shark smartphones, from basic MIUI settings to hidden engineering modes.

It’s important to understand that not every Xiaomi smartphone is physically capable of delivering 120 FPS. It all depends on the processor model, display type and firmware version. For example, the POCO F5 Pro with Snapdragon 8+ Gen 1 and AMOLED 120 Hz will cope easily, but the budget Redmi Note 12 with Snapdragon 4 Gen 1 is unlikely to pull a stable 120 frames even in light games. But even if your device is not from the flagship line – do not be upset: we will show you how to squeeze the most of what is.

Warning: some methods require unlocking the bootloader and root rights, which deprives you of warranty and can lead to unstable work. If you are not willing to take risks, focus on white-collar optimization methods, which are abundant in the article.

1. Check the hardware capabilities of your Xiaomi

Before you try to overclock an FPS, make sure your smartphone is physically capable of doing so.

• 📱 Processor model: only chips of the Snapdragon series 8xx (for example, 8 Gen 2, 8+ Gen 1) or Dimensity 9000+ can be stably issued 120 FPS In modern games. Budget Snapdragon. 6/7xx And Helio G will pull only that. PUBG Mobile at low settings.
• 🖥️ Display type: The screen should support 120Hz or 144Hz. You can check this in the model specifications or in the screen settings (Settings) → Display. → Update frequency: If the maximum is 90 Hz, 120 FPS You're not shining.
• 🔋 Cooling system: Liquid-cooled smartphones (e.g. Black Shark) 5 pro POCO F5) They keep the performance longer. Devices without radiators (e.g., Redmi Note) 11) They'll be trolling through 10-15 play-off.

To know exactly the specifications of your Xiaomi, install the CPU-Z app from Google Play or check the CPU model through Settings → About Phone → MIUI version → Full Specification.

2. customize MIUI for maximum performance

By default, MIUI limits performance to save battery and reduce heat, but for gaming, these limits only get in the way.

• ⚡ Enable Performance Mode: Go to Settings → Battery. → Performance mode and select High Performance, which will turn off background optimization and let the processor run at full speed.
• 🔄 Turn off adaptive refresh rate: in Settings → Display. → Update rate, lock in at 120Hz (if available). Adaptive mode can reduce FPS critically.
• 🚫 Stop optimizing for games: in Settings → Special facilities → Optimization MIUI Turn off all the switches. This will prevent the processor from automatically lowering the frequency.

We also recommend disabling all unnecessary animations and visuals: Settings → About Phone → MIUI version (click 7 times on the version to enable Developer Mode), then go back to Settings → Additional → For Developers and install:

• Window animation scale = 0.5x
• Transition animation scale = 0.5x
• Turn on GPU-acceleration = On.

💡

If your version of MIUI does not have Performance Mode, try enabling "Game Turbo Mode" in the game settings via the notification bar during gameplay.

3. Overclocking through the engineering menu (no root)

Xiaomi smartphones have a hidden engineering menu where you can manually raise performance limits, a method that works on most Qualcomm processors (Snapdragon series).

To get into the engineering menu:

1. Open the Phone app and enter the code: ##4636##.
2. Select Battery Information (or Usage Statistics in English firmware).
3. Click on the three dots in the top right corner and select Battery Settings.
4. In the Productivity Limitation section, uncheck all the ticks.

For more in-depth customization, use the code ##225## (calibration menu) or ##36446337## (performance tests). MIUI 14+.

4. Optimize Games with Game Turbo

Game Turbo is Xiaomi's proprietary game management utility, which allows you to fine-tune the performance for each application separately, to enable 120 FPS:

1. Launch the game, then call the Game Turbo panel by swiping your finger from the top right corner of the screen (or swipe over the game's floating icon).
2. Push the gear. ⚙️, open up.
3. Choose Productivity → Tall.
4. Activate Allow High FPS (if there is one).
5. Turn off Battery Optimization and Automatic Temperature Reduction.

For some games (such as Call of Duty: Mobile or Genshin Impact), additional graphics settings are available in the Game Turbo, where you can manually set 120 FPS or Max FPS if the game supports it.

5. Acceleration with root and custom cores

If you're willing to take drastic measures, unlocking the bootloader and installing the custom core can give you an FPS boost of 20-30%.

Here's what you're gonna need:

• 🔓 Unlocked bootloader (instructions on the official Xiaomi website).
• 📱 Established TWRP ornamental.
• 🔧 Overclocking-enabled core (e.g. KernelSU, Perseus or FrancoKernel for your model).
• 📊 App for overclocking control: Kernel Adiutor or EX Kernel Manager.

After installing the custom core in Kernel Adiutor, you can:

• Increase the maximum CPU/GPU frequency (e.g., from 2.8 GHz to 3.2 GHz for Snapdragon 8 Gen 2).
• Turn off the trottling when heated (dangerous for the battery!).
• Optimize the task scheduler for games.

💡

Acceleration through the custom core gives you maximum FPS gain, but reduces battery life and can lead to overheating. Use only if you are confident in the cooling system of your smartphone.

Important: On Dimensity-powered devices (like the Redmi K60 Ultra), overclocking the GPU through the kernel often results in artifacts in games. For these chips, it’s better to limit CPU optimization and disabling trottling.

6.Cooling and nutrition: how to avoid trottling

Even the most powerful Xiaomi will start to “strangle” performance if the temperature of the processor exceeds 45-50 ° C. To avoid this:

• ❄️ Use an external cooler (e.g. Black Shark FunCooler Pro) that lowers the temperature by a few hours. 5-10°C, which allows you to keep the high frequencies longer.
• 🔌 Play from the charge (preferably with power) 30W+). In battery mode, the smartphone limits productivity.
• 🧊 Replace the thermopaste (relevant to older models like this) POCO F1). A new paste can reduce the temperature 3-7°C.

Also, watch for battery power: if it's below 20%, the system automatically reduces performance. The optimal range for gaming is 40-80%.

💡

If your Xiaomi is getting hot, try lowering the screen resolution in the game settings. For example, in PUBG Mobile, switching from Ultra HD to HD will reduce the load on the GPU by 20-30%, and FPS will increase.

7.Graphics settings in games for 120 FPS

Not all games support 120 FPS on mobile devices, but here is a list of popular games and their features:

• 🎮 Call of Duty: Mobile supports 120 FPS Snapdragon on Snapdragon 8xx Dimensity 9000+. Included in the graphics settings (FPS: Max).
• 🎮 PUBG Mobile: maximum 90 FPS (120 FPS available only in emulators or on Black Shark with custom firmware).
• 🎮 Genshin Impact: 60 FPS — The ceiling is for the mobile version. FPS You need an emulator on a PC.
• 🎮 Fortnite Mobile (via GeForce) NOW): 120 FPS with good internet (50)+ Mbit/s).
• 🎮 Honor of Kings / Arena of Valor: 120 FPS Available on Xiaomi flagships with Snapdragon 8 Gen 2.

In most games, 120 FPS is included as follows:

1. Open the settings → Graphics.
2. Select the frame frequency: Ultra or Max.
3. Set Graphics Quality: Balanced (high quality may limit FPS).
4. Turn off Vertical Synchronization (V-Sync).

8.Alternative methods: emulators and cloud gaming

If your Xiaomi isn’t pulling 120 FPS in native games, consider:

• 🖥️ Emulators (like BlueStacks or MuMu Player) on a PC with a good graphics card, you can squeeze 120.+ FPS Even in Genshin Impact.
• ☁️ Cloud Gaming: GeForce NOW — 120 FPS In Fortnite, Cyberpunk 2077, Xbox Cloud Gaming - 60. FPS, But no lags. Boosteroid, 120. FPS in Valorant and CS2.
• 📱 Game ICE Mode (Black Shark only): Physical triggers and extra buttons help you react faster in shooters.

For cloud gaming, your Xiaomi should support Wi-Fi 6 or have a stable connection to 5G. Latency (ping) should not exceed 30 ms.

💡

Cloud gaming is the best way to get 120 FPS on weak smartphones, and the main thing is a good Internet and controller (for example, Xiaomi Game Controller).
