How to Overclock Xiaomi for Games: From Basic Settings to Extreme Optimization

Smartphones Xiaomi, Redmi and POCO They have long been known as some of the best mobile gaming devices in their price range, but even flagship models like the Xiaomi 14 Ultra or the other. POCO F6 Pro eventually begin to “brake” in modern games like Genshin Impact, PUBG Mobile or Call of Duty: Mobile. The reasons are not only in the hardware, but also in software optimization - especially when it comes to firmware. MIUI with its background processes and aggressive energy management.

In this article, we will analyze 10 working methods of acceleration – from safe tweaks in settings to radical methods like overclocking. GPU All instructions are validated on current models (2020-2026) and do not require root rights unless otherwise stated. Importantly, some methods can reduce battery life by 15-30%, but will increase the rate of growth. FPS Up to 20-40% in resource-intensive games.

Activation of the performance mode in MIUI

The easiest and safest way is to turn on the hidden Maximum Performance mode, which disables the restrictions on heating and power consumption. MIUI 12-14, but hidden by default.

To activate it:

• 📱 Open the Settings. → Battery and productivity → Battery mode.
• 🔧 Select High Performance (if not, read on).
• 🔍 If there is no option, enter Performance in the Settings Search and select Special Settings → Productivity.
• ⚡ Activate the Maximum Performance Switch (could be called Extreme Performance on global firmware).

Some models (e.g. Redmi Note 12 Pro)+) This mode is blocked after the update, in which case it will help to reset the battery settings:

⚠️ Warning: Maximum performance mode ignores the temperature limits of the processor. During long gaming sessions (more than 1 hour), overheating to 50-55 is possible.°C and forced frequency reduction (trottling) Use cooling stands or take breaks every 40 to 50 minutes.

2. Optimization of background processes and autoboot

MIUI It's known for aggressively controlling background processes, even in games, PUBG Mobile may suddenly start to lag because the system killed the com.tencent.ig background process to save battery.To avoid this, you need to manually configure exceptions.

Do the following:

• 🛠️ Go to Settings. → Annexes → Application management → Auto-start.
• 🎮 Enable autoplay for your game (e.g. Genshin Impact or Call of Duty: Mobile).
• 🔄 Go back and select the battery. → Choice of applications → No restrictions.
• ➕ Add the game to the list and install it without restrictions.

For models with MIUI 14 It is also recommended to disable “Smart Optimization»:

1. Go to Settings. → The phone.
2. Tap 5 times on the MIUI version to activate Developer Mode.
3. Back to Settings → Additionally. → For developers.
4. Turn off optimization. MIUI and Background optimization.

💡

After optimizing MIUI Reboot your smartphone. This will clear the cache of system services and apply the changes correctly.

3.Acceleration GPU and processor (without root)

Starting with Snapdragon 8 Gen 1/2 Dimensity 9000/9200, Xiaomi smartphones support dynamic overclocking through hidden engineering menus.This method does not require root rights, but only works on some models (list below).

Instructions for acceleration GPU Adreno (for Snapdragon):

1. Install the app GPU Performance Tuner (official from Qualcomm).
2. Open it and select a High Performance profile.
3. In the Advanced section, increase GPU Frequency at 10-15% of the standard value (for example, from 840 MHz to 950 MHz).
4. Save the settings and restart the device.

For MediaTek processors (e.g., Dimensity 1200 in Redmi) K50):

• 📲 Install. MTK Engineer Mode (requires to enable installation from unknown sources).
• 🔧 Move to the MTK Settings → Hardware Testing → CPU Stress Test.
• 📊 In the section CPU Frequency increase the maximum frequency of the large core by 5-10% (for example, from 2.85 GHz to 3.0 GHz).

⚠️ Attention: Overclocking through MediaTek's engineering menu can lead to a hard brick if you exceed the safe limits.Do not increase the frequencies by more than 15% and always monitor the temperature through the AIDA64 or CPU Monitor.

4. Cleaning the system of garbage and cache

In time. MIUI It accumulates gigabytes of unnecessary files: game cache, update residues, duplicate photos from the Gallery. This not only takes up space, but also slows down the read/write of data - critical for games that are actively working with storage (for example, Genshin Impact with its open world).

How to clean the system correctly:

Remove the game cache through Settings → Warehouse|Disable automatic download of media in Telegram/WhatsApp|Clean Downloads folder from unnecessary files|Remove duplicate photos through the gallery → Management → Duplicate|Perform a deep cleaning through MIUI Optimizer-->

Use for deep cleaning MIUI Optimizer (requires) ADB):

adb shell pm grant com.miui.optimizer android.permission.WRITE_SECURE_SETTINGS


adb shell am start -n com.miui.optimizer/.MainActivity

In the app, select:

• 🧹 Deep Clean → System Junk.
• 🗑️ App Cache → tag the games and press Clean.
• 📁 Large Files → delete files size >500MB (e.g., old screen recordings).

After cleaning, restart the device and check the performance in 3DMark Or GFXBench. FPS It can reach 10-15% by reducing the load on the storage.

5. Customize graphics in games through Game Turbo

Xiaomi is embedding Game Turbo, a similar utility to Game Space from other brands, into the firmware, allowing you to fine-tune graphics, limit background processes, and even block notifications during play, but by default many features are disabled.

How to set up Game Turbo for maximum FPS:

1. Open Game Turbo (the icon on the desktop or in the app menu).
2. Add your game to the list (like Honor of Kings).
3. Slip on the game and select Performance Settings.
4. Install: 🎯 Performance mode → Extreme. 🖥️ Permission → Native (or) 720p weak-model). 🔄 Frequency of personnel → Max (e.g. 120) FPS for PUBG Mobile). 🚫 Limitation FPS → Disconnected.

For models with AMOLED-screens (for example, Xiaomi 13 Ultra) also include:

• 🌑 Dark theme in games (reduces the load on the game) GPU).
• 🔦 Local dimming (reduces energy consumption).

6. Disconnecting unnecessary Xiaomi services

MIUI It runs dozens of background services by default, from Mi Cloud to Xiaomi Service Framework, many of which not only consume battery, but also load. CPU Even when you're playing, they can be turned off without any system consequences.

List of safe to disable services (via ADB):

adb shell pm disable-user --user 0 com.miui.analytics


adb shell pm disable-user --user 0 com.xiaomi.ab




adb shell pm disable-user --user 0 com.miui.systemAdSolution




adb shell pm disable-user --user 0 com.xiaomi.joyose




adb shell pm disable-user --user 0 com.miui.hybrid




adb shell pm disable-user --user 0 com.xiaomi.payment

To shut down without ADB:

1. Go to Settings → Applications → Application Management.
2. Slip three points up there. → Show all the processes.
3. Find and disconnect: 📊 Miui Daemon (unless you use themes). 🌐 Browser (if you use Chrome). 📦 Download Provider (if you don’t download files through a standard manager).

⚠️ Note: Do not disable services called com.android. or com.qualcomm. – this can lead to network loss or camera problems.

7.Storage optimization: from file system format to read speed

Many people don’t know that the file system format directly affects the download speed of games. For example, Xiaomi defaults to format memory cards in exFAT, which is slower than the previous version. F2FS 20-30% for small files (and there are thousands of them in Genshin Impact or PUBG Mobile).

How to speed up reading/writing:

• 📁 If the game is installed on a memory card, move it to the internal memory (even if it is installed on the memory card). UFS 2.1 faster than the microSD UHS-I).
• 🔄 Format the map in F2FS (requires rooting TWRP).
• 🗃️ Turn on Force. F2FS In the core (for advanced users).
• 📥 Disable Auto-Optimize Storage in Settings → Warehouse → Additionally.

To check the storage speed, use AndroBench.

• 📈 Consecutive reading: >500 MB/s (for example, UFS 3.1).
• 📉 Random reading (4K QD32): >50 MB/s.

If the speed is lower, try resetting the storage settings:

adb shell sm reset-storage

8 Extreme methods: core, firmware and cooling

If the previous methods didn't increase enough, you can go further -- but you need root rights or unlocked bootloaders, and these methods maximize productivity, but they're risky.

Ways for Advanced Users:

• 🔥 Custom core firmware (e.g. FrancoKernel or Kirisakura for Snapdragon). +15-20% of performance from optimized governors.
• ❄️ Installation of a liquid metal thermopaste (e.g. Coollaboratory Liquid Ultra) reduces the temperature by 10-15°C, preventing trottling.
• 🔧 Undervolting CPU/GPU through EX Kernel Manager: Allows you to reduce voltage without losing performance by reducing heat.
• 📡 Disabling restrictions by region (e.g., unlocking 120) FPS into PUBG Mobile for all servers).

⚠️ Warning: Replacing the heat paste on Xiaomi requires a complete disassembly of the device. On liquid-cooled models (such as the Black Shark 5 Pro), self-repair can lead to a leak of coolant and the phone fails. If you are not sure, contact the service center.

💡

Custom firmware like LineageOS or Pixel Experience is NOT recommended for gaming – they are often devoid of optimizations for games that are in the original. MIUI.
