How to Enable Maximum Performance Mode on Xiaomi: The Complete Guide

Modern Xiaomi smartphones are equipped with powerful processors and advanced cooling systems, but by default they work in a balanced mode. It is a trade-off between performance and power consumption that suits most users. However, gamers, fans of multi-tasking or those who work with resource-intensive applications often face a situation where the device begins to “brake” or limit the frequency of the processor, in which case the maximum performance mode comes to the rescue — a hidden MIUI feature that allows you to unleash the full potential of iron.

But before you activate this mode, it is important to understand its features. Unlike standard energy saving profiles, the maximum performance mode disables most of the restrictions on the operation of the processor, graphics accelerator and RAM. This means that the smartphone will work faster, but also heat up more and discharge faster. In addition, on some Xiaomi models, this mode can be blocked by the manufacturer or require additional manipulations to turn on.

In this article, we will discuss in detail how to turn on the maximum performance mode on different Xiaomi devices, which models support it, and how to minimize the negative consequences for the battery. MIUI, which will help to fine-tune the productivity to your needs.

What is the maximum performance mode and why it is needed

Maximum performance mode (sometimes called Performance Mode or Extreme Mode) is a special smartphone profile that disables CPU, GPU and RAM clock limits. In normal MIUI mode, it automatically reduces performance to reduce heat and extend battery life. However, in maximum performance mode, these restrictions are removed, allowing:

• 🎮 Increase. FPS In games (especially heavy projects like Genshin Impact or Call of Duty Mobile)
• ⚡ Speed up video rendering and photo processing in professional applications
• 🔄 Improve multitasking (for example, working with multiple applications at the same time)
• 📱 Reduce delays in starting resource-intensive tasks

But there's a downside to this, too: As the processor runs at the limiting frequencies, the smartphone gets hotter and the battery runs 1.5 to 2 times faster, and running in this mode can shorten battery life because of the increased number of charge-discharge cycles.

Important: On some Xiaomi models (especially budget ones), maximum performance can be locked at the firmware level, because weak cooling systems can’t cope with heat generation when overclocking the processor.

What Xiaomi models support maximum performance

Not all Xiaomi smartphones have the ability to enable maximum performance mode, which is typically available on flagship and game models equipped with powerful processors and cooling systems.

• 📱 Xiaomi Black Shark (all models including Black Shark 5 Pro)
• 📱 Xiaomi 12 Pro, Xiaomi 12S Ultra, Xiaomi 13 Pro
• 📱 POCO F4 GT, POCO F5 Pro
• 📱 Redmi K50 Gaming Edition, Redmi K60 Pro

On budget models (such as the Redmi Note 11 or POCO M5), this mode may be missing or hidden, and it is worth considering that on some devices the feature is only available after unlocking the bootloader or installing custom firmware.

How do you check for support? If your model isn't on the list above, try looking for Performance or Game Mode in the settings. If it's not, chances are your smartphone's maximum performance mode isn't supported.

⚠️ Note: Some Xiaomi models (e.g. Xiaomi) 12T Pro) maximum performance mode may be automatically switched off when overheating above 45°C. This is protection against damage to the processor.

Method 1: Enable via MIUI settings (official method)

If your smartphone supports maximum performance mode, the easiest way to activate it is through standard MIUI settings. Instructions are suitable for most flagship Xiaomi, POCO and Black Shark models.

Steps to include:

1. Open Settings → Battery and Performance.
2. Select Performance Mode (on some models it may be called Processor Performance or Game Optimization).
3. In the list of available modes, select Maximum Performance or Extreme Mode.
4. Confirm the selection and restart the device (some models do not require a reboot).

On Black Shark smartphones, the path may be slightly different:

1. Press the Shark Space icon on the home screen.
2. Select Performance Settings → X Mode.
3. Activate the switch Maximum performance.

⚠️ Attention: On some firmware MIUI After the upgrade, the maximum performance mode can be reset to the standard, in which case it will have to be turned on again.

Method 2: Activate through the Engineering Menu (for advanced users)

If MIUI does not have an explicit point to enable maximum performance mode, you can try activating it through the engineering menu, which works on most Xiaomi smartphones, but requires caution - improper actions can lead to malfunctions of the device.

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that opens, select Battery Information (or Battery Information).
3. Scroll down and find the Performance profile (if not, your model doesn’t support this method).
4. Choose High Performance or Extreme.
5. Save the changes and restart the smartphone.

If #4636### doesn’t work, try an alternative method:

1. Install the MTK Engineering Mode app (available on Google Play).
2. Open it and go to the Hardware Testing → CPU section.
3. Find the CPU Governor option and select Performance.
4. Save the settings.

Important: After activating the mode through the engineering menu, monitor the temperature of the processor. If the smartphone begins to overheat (above 50 ° C), it is better to return the settings to the original state.

Method 3: Use ADB-Teams (for experienced users)

If standard methods don’t work, you can try to turn on maximum performance mode via ADB (Android Debug Bridge), which requires connecting your smartphone to your computer and basic command line knowledge.

What you need:

• 💻 A computer with installed Xiaomi drivers and ADB Tools.
• 📱 Smartphone with enabled debugging USB (Settings → The phone. → Version. MIUI (press 7 times) → Additionally. → For developers → Debugging by USB).
• 🔌 USB-cable (preferably original).

Step-by-step:

1. Connect your smartphone to your computer and allow debugging over USB.
2. Open the command prompt (Windows) or terminal (macOS/Linux) and type: adb devices Make sure your device appears in the list.
3. Enter the command to enable maximum performance mode: adb shell settings put global power_profile 1 (Some firmware may require adb shell setprop persist.sys.performance 1)
4. Reboot your smartphone: adb reboot

To return the standard settings, use the command:

adb shell settings put global power_profile 0

💡

If ADB Does not recognize the device, try reinstalling Xiaomi drivers or using another USB-Also check if debugging is on. USB developer-setting.

⚠️ Attention: On some firmware MIUI team ADB If you're trying to change the performance profile, you can block them.

How to check that the maximum performance mode is working

Once you activate the maximum performance mode, it is important to make sure that it actually works.

• 📊 Performance tests: Run a benchmark (e.g. AnTuTu or Geekbench) and compare the results before and after the mode is turned on%.
• 🌡️ Temperature monitoring: Use the app CPU Monitor AIDA64, In maximum performance mode, the clock speed should be kept at maximum, and the temperature should rise faster.
• 🎮 Test in games: Run a resource-intensive game (for example, PUBG Mobile at maximum settings and check FPS using the built-in counter or GameBench app.

If no changes are observed after the regime is activated, the following reasons may be possible:

• The firmware blocks changes (especially for global versions of MIUI).
• The smartphone has software that limits performance (for example, Game Turbo in the background).
• The battery is discharged below 20% – in this case, MIUI automatically reduces performance.

💡

If the smartphone gets too hot or turned off after the maximum performance mode is activated, return the standard settings immediately. This may indicate a malfunction of the cooling system or battery.

How to minimize the negative effects of the battery

Maximum performance mode significantly increases the load on the battery. To extend its life and avoid premature wear, follow these recommendations:

• 🔋 Don’t use the mode all the time. only enable it when necessary (for example, for games or video rendering), and the rest of the time return to a balanced profile.
• 🌡️ Watch the temperature. If the smartphone heats up above 45.°C, take a break or cool it (e.g., using a cooling stand).
• 🔌 Avoid full discharge. In maximum performance mode, the battery discharges faster - try to recharge the device at a charge level of 20-30%.
• ⚡ Use the original RAM. Fast charging with uncertified adapters can accelerate battery degradation.

You can also optimize MIUI settings to reduce the load:

1. Turn off background activity of unnecessary applications (Settings → Apps → Permissions → Auto Run).
2. Reduce the screen resolution (unless it is critical to your tasks).
3. Activate Battery Savings mode in settings when maximum performance is not needed.

Critical information: On Xiaomi smartphones with a battery capacity of less than 4000 mAh, constant use of maximum performance mode can reduce battery life by 30-40% in a year.
