How to Overclock a Xiaomi Device: From Standard Settings to Deep Optimization

Owners of Xiaomi equipment — from Redmi and POCO smartphones to Mi TVs — often face the desire to squeeze out the device to the maximum performance. But what exactly is behind the term “overclocking”? For some, this means faster animation and responsiveness of the interface, for others, increasing the clock speed of the processor, and for others, optimizing the background for games or multimedia.

It’s important to understand that overclocking is not only a potential increase in speed, but also the risks of overheating, shortening battery life, or even failure. In this article, we’ll look at legitimate methods (built-in settings, performance modes) and advanced ones (rooting, custom cores), as well as alternative ways to speed up work without physically interfering with hardware.

1. Standard performance settings in MIUI

Before resorting to radical measures, check the built-in MIUI tools. the manufacturer has already provided several modes of operation that can be activated without risk to warranty.

Most Xiaomi smartphones (starting with MIUI 12) are available on:

• 🔋 Battery Mode: Switch to "Performance" in Settings → Battery. → Battery mode. This will turn off background optimization and increase the CPU clock speed.
• 🎮 Game mode: c Settings → Special facilities → Play mode: Enable the "Improving Performance" option, and the system automatically allocates resources to the running game.
• ⚡ Accelerate animation: activate "No animation" or "Animation" ×0.5" in Settings → The phone. → Version. MIUI (Click on the version 5 times, then go to the Developer Settings → Scale of animation).

On Mi TVs (such as Mi TV Q2 or Redmi Smart TV X), similar options are hidden in Settings → Device → Performance Mode. Here you can choose between Balanced, Energy Saving and Maximum Performance. The latter option speeds up interface rendering and reduces channel switching delays.

💡

If after changing the battery mode, the device began to warm up, return the settings to the "Balanced" mode and clear the application cache in Settings → Storage → Clear the cache.

2. Background optimization: what to turn off for acceleration

One of the most effective ways to break up Xiaomi is to free up RAM and CPU from unnecessary processes, and even on flagships like the Xiaomi 13 Ultra, background services can eat up to 30% of resources.

What can be safely disabled:

• 📱 Auto-Update Apps: In Google Play → Settings → Auto Update Applications Select "Do not update automatically".
• 🔄 Synchronizing Unnecessary Accounts: Go to Settings → Accounts and disable sync for underutilized services (e.g. Mi Cloud, unless you use backups).
• 📊 Analytics and Reports: Deactivate Settings → Additionally. → Sending error reports and settings → Confidentiality → Personalization of recommendations.
• 🎵 Music widgets: if you don’t use Mi Music, remove the widget from the home screen – it constantly consumes RAM.

For Xiaomi TVs, it is critical to disable automatic firmware updates in the background (if enabled).This will prevent sudden hangings while watching movies. Way: Settings → About the device → System Update → Settings (cogs) → Auto Update.

3. Overclocking through developer modes

Hidden settings for developers allow fine-tuning performance, but require caution. Incorrect settings can lead to overheating or spontaneous reboots.

How to turn on and what to change:

1. Activate Developer Mode: Settings → About Phone → MIUI version (tap 5 times).
2. Go back to the basic settings and open a new section of Developer Settings.
3. Find the options: 🔧 Limitation of background processes → Set a "Maximum 2 process". 🔥 Do not turn off the screen while charging (useful for long-term tasks). 🖥️ GPU-acceleration → turn on "Compulsory" GPU-acceleration" (may cause artifacts in some applications!). 🔄 Animation of windows/transitions → set 0.5x or shut it down completely.

On Xiaomi TVs, the developer mode is turned on similarly (tap on the Android version). TV In Settings → The device → It's useful to activate Debugging on the device. USB and Enforcement of use GPU rendering 4K-content.

4. Advanced methods: rooting and custom firmware

If standard methods fail, users resort to rooting and custom firmware installations, which allow them to overclock the processor, change the GPU frequencies, and even replace the core.

• ⚠️ Deprive warranties (even if the later returns the stock firmware, the service center can detect traces of interference).
• ⚠️ Increase the risk of brick (turning the device into a “brick” if the firmware error).
• ⚠️ Deteriorating security (root access opens up vulnerabilities for malware).

Popular tools for overclocking:

Critical information: On devices with MediaTek processors (such as the Redmi Note 11 or POCO M4 Pro), overclocking through custom cores often leads to a “brick” due to a blocked bootloader. Before any manipulations, check the support for your model on the XDA Developers forum.

5. Alternative methods of acceleration without acceleration

You don't always have to increase the CPU frequencies to make the device run faster, and often you just need to optimize your existing resources.

For smartphones:

• 🧹 Cache Cleanup: Use the built-in Settings utility → Warehouse → Clear the cache or app SD Maid.
• 🗑️ Bloatware Removal: Even without root, you can disable unnecessary system applications through Settings → Annexes → Show all applications → Choose unnecessary → Shut down.
• 🔄 Factory reset: radical but effective method. Pre-save data!

For Xiaomi TVs:

• 🎛️ Reset Smart TV default: Settings → The device → Resetting settings (helps with interface brakes).

💡

Before resetting your settings on your Xiaomi TV, write down your Mi Account details – after the reset, you will need to re-authorize to unlock some features (for example, Google Play).

6 Risks and how to minimize them

Any overclocking is a tradeoff between performance and reliability.

⚠️ Note: On devices with Qualcomm Snapdragon processors 8 Gen 1/2 (for example, Xiaomi 12 pro POCO F4 GT) forced-dispersal GPU Kernel Adiutor can cause thermal throttling already in the 40°C, which will lead to a sharp fall FPS play.

How to reduce the risks:

• 🌡️ Temperature monitoring: use applications like CPU Monitor AIDA64 heat-tracking.
• 🔋 Battery control: Do not overclock the device if the charge is below 20% – this accelerates battery degradation.
• 🛡️ Data backup: Before any manipulation, save data via Mi Cloud or TWRP.
• ⚖️ Gradual frequency increase: when manually overclocking, increase values by 5-10% and test stability.

On Xiaomi TVs, the main danger is damage to the matrix during long-term acceleration. If you notice artifacts on the screen (bands, flickering), immediately return the settings to the factory settings.

7. Acceleration for specific tasks: games, multimedia, work

It's not always necessary to overclock a device globally, but often it's enough to optimize it for a specific task:

Call of Duty Mobile (Genshin Impact)

• 🎮 Use the Game Turbo (built-in) MIUI play-in).
• 🔧 B Settings → Special facilities → Play mode: Enable "High Performance" and "Switch off Automatic Brightness".
• 🖥️ For POCO F3/F4 GT Branded shoulder triggers available – set them up in Game Center.

For multimedia (streaming video, editing):

• 🎥 B Settings → Display. → Select permission. FHD+ instead QHD+ (resource-saving GPU).
• 🔊 Turn off sound effects in Settings → Sound. → Sound effects.
• 📱 To edit videos in CapCut or KineMaster, turn on “Performance Mode” in the app settings.

For work (multi-tasking, office tasks):

• 📊 Use the "Desktop" mode (Settings) → Display. → Desktop mode on some models).
• 📋 Disable notifications from unnecessary apps in Settings → Notifications.
• 🔄 Enable "App Fixing" in Multitasking (Swipe Up) → pinch the app icon → "Secure").
