How to squeeze the most out of Xiaomi: overclocking, cooling and setting up for a record-breaking FPS

Owners of smartphones Xiaomi, Redmi and POCO "Frequently encounter situations where hardware devices are capable of more than they show in games or benchmarks." - Snapdragon processors 8-Dimensity, or even mid-budget Snapdragon 7xx can demonstrate productivity on 20-30% If you know how to wake them up, you know, but there's a catch: uncontrolled acceleration leads to overheating, trottling and shortening battery life.

This article is not about the mythical "cheat damage", but about the legitimate optimization methods used by experienced gamers and enthusiasts. We will understand how to safely unlock the hidden potential of Xiaomi through system settings, engineering menus, third-party utilities and even hardware modifications. It is important to understand that this is not about "hacking" the device, but about competent management of resources that the manufacturer artificially limits for stability.

Warning: some methods require unlocking the bootloader, root rights or installing custom firmware. This will void the warranty and can lead to a device blink if you do not take risks, focus on the "soft" methods from the first sections.

1.Diagnostics of current performance: benchmarks and monitoring

Before you try to “increase damage”, you need to understand what your Xiaomi is capable of in standard mode.

• 📊 3DMark Or GFXBench, for testing graphics performance in games. FPS Stability (stability of staff), not just by average.
• 🔥 CPU Throttling Test: shows how fast the processor starts to trottle (reduce frequencies) when loaded: 0% trottling in the first 10-15 minute.
• 📈 AIDA64 DevCheck – for temperature, frequency monitoring CPU/GPU and energy consumption in real time.

Key parameters to pay attention to: CPU temperature – if it exceeds 75°C under load, acceleration will only make trottling worse. FPS In games, they often “sink” due to background processes or limitations MIUI. Autonomous life – if the smartphone is discharged for 2-3 In the game, energy optimization will be a priority.

Example: POCO F5 Pro (Snapdragon 8+ Gen 1) In Genshin Impact with standard settings FPS fluctuate 50-60 Iron is capable of stable, but iron is capable of 60+. The reason is aggressive trottling MIUI after 5 play-off.

2. Software optimization: settings MIUI and engineering menu

The safest way to increase productivity is through hidden settings MIUI These methods don't require root rights, but they do have a noticeable increase in games.

Step 1: Turning off background processes

Go to Settings. → Annexes → Application management → Autorun and disable autorun for all unnecessary applications (social networks, instant messengers, system utilities like Mi Video or Music). → Battery → Performance mode select High Performance mode.

Step 2: Engineering menu (MTK qualcomm)

For Qualcomm processors (most of Xiaomi’s flagships):

1. Enter the number ##4636##.
2. Go to the Information tab. → Battery information.
3. Check the Power Save Mode option – it should be OFF.

For MediaTek processors (Redmi Note series, POCO M):

1. Enter the code ##36446337## (Engineer Mode).
2. Go to Hardware Testing → CPU.
3. Turn it off. CPU Core Control and Thermal Throttling (Temporary!).

💡

After testing in the engineering menu, return the trottling settings to the original state - prolonged operation without thermal control reduces the life of the chip.

Step 3: Gamer mode in MIUI

B Settings → Special facilities → Activate gamer mode:

• 🎮 Performance Notices (shows) FPS and real-time temperature).
• ⚡ Network optimization (reduces ping in online games).
• 🔇 Block notifications (prevents lags from background processes).

3. Acceleration through ADB: removal MIUI

Deeper optimization requires a connection to PCs and commands ADB (Android Debug Bridge: This method doesn't require root rights, but resets some settings after rebooting.

Step 1: Preparation

1. Download the Google Platform Tools.
2. Turn on the debugging. USB In Settings → The phone. → Version. MIUI (Press 7 times on the line, then return to Additional settings → For developers).
3. Connect your smartphone to your PC and type the command: adb devices to make sure the device is identified.

Step 2: Teams for overclocking

For Snapdragon devices (Xiaomi) 13/14, POCO F5 Pro):

adb shell settings put global force_high_performance true


adb shell settings put global thermal_profile 0

These commands disable thermothrottle and force a high-performance profile to be set up.

For MediaTek (Redmi Note 12, POCO X5):

adb shell settings put global mtk_thermal_policy 0


adb shell settings put global mtk_cpu_boost 1

Step 3: Fixing FPS play

To get the game to use maximum graphics settings, enter:

adb shell settings put global force_fps 120

(Replace 120 with a value, such as 90 for Genshin Impact).

4.Castom firmware and cores: maximum acceleration

If you're willing to take risks, installing custom firmware or kernel will give you the biggest performance boost.

• 🔧 ArrowOS or Pixel Experience – “clean” firmware without restrictions MIUI, with better optimization for gaming.
• ⚡ KernelSU or FrancoKernel - custom cores with overclocking CPU/GPU and improved thermal control.
• 🎮 DerpFest – firmware with pre-optimized settings for gaming.

Installation instructions (briefly):

1. Unlock the bootloader via Mi Unlock Tool (requires Mi Account binding and waiting) 7-14 days).
2. Install custom TWRP or OrangeFox recavators.
3. Swipe the firmware and core through the Recovery (be sure to do a backup Nandroid!).
4. Configure overclocking options in the Kernel Auditor app or EX Kernel Manager.

Example of core settings for Snapdragon 8 Gen 2 (Xiaomi 13 Ultra):

⚠️ Attention: Acceleration through custom cores can lead to overheating over 90°C and automatic shutdown of the device. Use only with active cooling (see section 5) and temperature monitoring through AIDA64.

5. Hardware modifications: cooling and power

Iron-based improvements provide steady productivity gains without the risk of software failure.

1. Passive cooling

2. Active cooling

• 💨 External coolers - Razer Phone Cooler or Black Shark FunCooler Pro reduce the temperature 15-20°C under intense load.
• 🔋 USB-Fans are a budget option (for example, Baseus Cooling Fan), but require a connection to a powerbank.

3. Nutrition modification

• ⚡ Replace the battery – if the capacity has fallen below 80%, replace it with a new one (original or Green Mi with increased capacity).
• 🔌 Use of the PD-Charging – Connecting to the Source 30W+ during the game prevents subsidence FPS energy-saving.

Example: Redmi K60 Pro with installed cooler FunCooler Pro and thermal gaskets Thermal Grizzly time before the start of trottling increases from 7 to 25 minutes, and FPS Call of Duty Mobile grows from 110 to 120 stable.

⚠️ Warning: When using external coolers, avoid getting moisture into the connector USB-C. Condensate from sharp cooling can cause a short circuit. After the game, let the smartphone heat up to room temperature before charging.

6. Optimization for specific games

Some games have hidden graphics settings that can be changed through configuration files or ADB. Let's take a look at popular cases:

Genshin Impact

Call of Duty: Mobile

PUBG Mobile

Xiaomi. 12T Pro (Snapdragon 8+ Gen 1) after-use ADB-commands and modifications of the config PUBG Mobile shows stable performance 90 FPS permitting 1920×1080, while in the standard mode FPS sink 70-80.

7. Alternative methods: from model substitution to undervolting

For advanced users, there are some non-obvious ways to increase productivity:

1. Substitution of the device model (Device Spoofing)

Some games (such as Genshin Impact) are limited. FPS for specific models. ADB You can “substitute” the model for the supported model:

adb shell setprop ro.product.model "2206123SC"

(where 2206123SC — Xiaomi 12S Ultra, which officially supports 60 FPS).

2. Undervolting (Undervolting)

Reducing kernel stress CPU/GPU It allows you to reduce heating and trottling without losing performance:

• 🔧 Reduce the tension by 10-15 MV for each core, testing stability.
• 🔥 Optimal range: 850-950 mV for large Snapdragon cores.

3.Use of Game Space

V MIUI 14+ It's got a built-in Game Space, which automatically optimizes resources for games:

• 🎮 Include in Settings → Game Space → Performance option Extreme Performance.
• 📊 Add the game to the list and activate Deep Optimization.

💡

Undervolting is one of the most effective methods of combating trottling. The right setting can reduce the temperature of the body. 10-15°C without loss of productivity.

8 Risks and how to minimize them

Any optimization has a downside, and here are the key risks and ways to avoid them:

If you notice the following symptoms, immediately return the settings to standard:

• 🔥 Processor temperature above 85°C for 5+ minute.
• ⚡ The smartphone suddenly turns off when loaded.
• 🎮 FPS In games, it is lower than before optimization (a sign of aggressive trottling).
• 🔋 The battery is discharged for 1-1.5 hours in games (norm for flagships — 2.5-3 hour).

Safety checklist:

Do not exceed the temperature of 85°C|

Use only verified firmware with XDA|

Make a backup before any changes|

Return standard settings at the first sign of instability|-->
