Performance mode on Xiaomi through Activity Launcher: hidden settings for gamers and advanced users

Xiaomi’s MIUI-based smartphones hide many useful features from users, one of which is the performance mode, which optimizes the processor, graphics accelerator and RAM for maximum returns in games, video rendering or resource-intensive tasks. However, it is not officially available on all models, the manufacturer limits the functionality for the “average” user.

The secret path to activation is through the system application Activity Launcher, a tool that allows you to run hidden activations (setting screens) that Xiaomi does not bring to the main menu.The method works on most devices with MIUI 12-14, including Redmi Note 10/11/12, POCO F3/F4/F5, Xiaomi 11T/12/13 and other models on Snapdragon or MediaTek. Importantly, some firmware may require pre-unlock OEM Unlock.

What is Activity Launcher and Where to Download It

Activity Launcher is an Android utility that scans installed apps and displays a list of all available Activity screens, including those hidden from the user. ROOT-right, but to work with system settings, permission to display over other windows is required.

You can download it for free from official sources:

📱 Google Play (the version for most users)
🌐 Official website (APK for devices without Google services)
🔍 APKCombo (alternative versions)

Before installing, check that your Xiaomi allows you to install applications from unknown sources (Settings → Applications → Special Rights → Install Unknown Applications). Also make sure that the MIUI version is not older than 2-3 years - on very old firmware, the path to performance mode may differ.

Step-by-step: how to enable the performance mode through Activity Launcher

The activation procedure takes no more than 5 minutes, but requires careful attention.

Open Activity Launcher and provide all the permissions you request (access to notifications and display over other windows).
In the search box, type Game Turbo or Performance – these are the keywords to filter the desired activities.
Find a paragraph called com.miui.performance.PerformanceModeActivity or similar (may vary depending on the model), usually hidden under System UI or MIUI System.
Slip on the activity found - a hidden menu with performance settings will open.
Choose Extreme Performance Mode or High Performance Mode.
Confirm the changes and restart the device.

After the reboot, check the mode in games or benchmarks (such as AnTuTu or the other). 3DMark). The difference in productivity can be achieved 15–25% into CPU/GPU-loads due to the disabling of background restrictions and increasing clock frequencies.

Check the version of MIUI (Settings → About the phone)

Install Activity Launcher from a verified source

Allow all application requests (notifications, overlays)

Close background applications before changing settings

Connect the charger (recommended for stability)-->

What Xiaomi models support hidden performance mode

The feature is available on most devices with Qualcomm Snapdragon processors (700/800 series) and some MediaTek Dimensity, but there are nuances:

Series of devices	Support for the regime	Notes
Xiaomi 12/12S/12T/13	✅ Yes.	Full support including Extreme Performance
POCO F3/F4/F5	✅ Yes.	May require pre-enabled Game Turbo
Redmi Note 10 Pro/11 Pro/12 Pro+	✅ Partially.	Only High Performance Mode is available
Redmi 9/10 (budget)	❌ No.	Weak processors do not support the regime
Black Shark 4/5	✅ Yes (+ subset)	It has its own menu, Shark Space.

On devices with Snapdragon 8 Gen 1/2 processors (Xiaomi 12 Pro, 13 Ultra), the mode is activated automatically when you run supported games through the Game Turbo.

What to do if you do not have PerformanceModeActivity?

If the Performance search fails, try 1. Enter Game or Turbo 2. Check for MIUI updates (sometimes renamed) 3. Install App Cloner and clone Activity Launcher with system application rights 4. Some firmwares have hidden the path in com.miui.gameturbo

Risks and consequences of activating the production mode

Enabling hidden settings is always fraught with potential problems.

🔥 Overheating: Prolonged operation in maximum performance mode can lead to trottling (automatic frequency reduction) or even emergency shutdown at critical temperatures.
🔋 Increased battery consumption: In Extreme Performance mode, autonomy falls on the 30–40% faster due to increased energy consumption CPU/GPU.
⚠️ System instability: Some firmwares may have interface lags or occasional reboots (especially on customized ones). ROM).
🚫 Reset on Update: After Major Updates MIUI Performance settings can be reset.

⚠️ Note: On devices with MediaTek Helio G processors (e.g. Redmi) 9/10) Forced performance modes can lead to graphic artifacts in games, due to the limitations of Mali-GPU drivers.

To minimize risks, use only when the charger is connected and monitor the temperature through applications like AIDA64 or CPU Monitor. The optimal temperature for the Snapdragon 8xx is up to 45 ° C, for Dimensity - up to 48 ° C.

💡

If the phone is getting warmer after activating, return the settings to Balanced Mode and clear the Game Turbo cache through Settings → Applications → Application Management.

Alternative ways to overclock Xiaomi without Activity Launcher

If Activity Launcher didn’t work for some reason, there are other methods to optimize performance:

🎮 Game Turbo: Built-in app for gamers (Settings) → Special facilities → Game Turbo: Allows you to allocate additional resources for games, but without deep customization CPU/GPU.
🔧 ADB-Commands: Adb shell settings put global force_high_performance True or change of parameters power_mode via sysfs.
⚡ Castom cores: On devices with an unlocked bootloader, you can install cores like Perseus or FrancoKernel, which offer advanced performance profiles.
🔄 Shutdown MIUI Optimizations: Through ADB: adb shell pm disable-user --user 0 com.miui.powerkeeper (removes background restrictions, but can increase battery consumption).

Important: ADB and custom core methods require unlocking the bootloader, which leads to data resets and loss of warranty. On devices with MIUI Global, some commands may be blocked.

💡

The safest alternative is to use the Game Turbo with manual profile settings for each game, which will not give you the same performance gains as the hidden mode, but there are almost no risks.

How to turn off the performance mode and return the standard settings

If after activation you are faced with overheating, rapid discharge or instability, you can return everything back in two ways:

With Activity Launcher: Open PerformanceModeActivity again. Select Balanced Mode or Battery Saver. Reboot the device.
Through Game Turbo Settings Reset: Go to Settings → Apps → App Management → Game Turbo. Click Storage → Clear Data. This will reset all performance profiles to factory ones.

⚠️ Attention: On some firmware (MIUI 14 for POCO F5) Resetting Game Turbo can lead to the disappearance of the point of the performance mode in Activity Launcher. In this case, only a complete reset or flashing will help.

If your phone continues to warm up after you turn off mode, check the background through Settings → Battery → Battery Use. Sometimes apps (like Facebook or TikTok) continue to consume resources in the background even after you return to standard settings.

FAQ: Frequent questions about performance mode on Xiaomi

❓ Does the performance mode work on all games?

No, the mode optimizes performance only for applications recognized by the system as games (via Game Turbo). To force-activate the mode for any application, you will need to manually add it to the list of games through the ADB: adb shell cmd appops set <package_name> android:power_optimize_exempt allow

❓ Can I turn on the mode without Activity Launcher?

On some firmware (MIUI 13 for Xiaomi 12T), the path to the performance menu is available through the standard settings: Open Settings → About phone. Tap 5 times on the MIUI version to activate developer mode. Go back to Settings → Additional → For developers. Find Processor Performance (if any).

❓ Why After the Regime Is Included FPS haven't grown up?

There are several reasons: The game is limited by FPS at the engine level (for example, Genshin Impact blocks 60 FPS on most devices); VSYNC is enabled in the game or driver settings; the processor reaches the thermal limit and reduces frequencies (trottling); on some devices (Redmi Note 11 Pro), the mode only increases the CPU, but does not affect the GPU. Check FPS through Game Tools (built-in counter) or third-party utilities like FPS Meter.

❓ Will the system work after the update? MIUI?

Depends on the type of update: Small updates (for example, with the MIUI 14.0.5 at 14.0.6) - settings will remain. Major updates (c) MIUI 13 on MIUI 14) — high probability of resetting. In this case, you will have to re-activate the mode through Activity Launcher. Before updating, back up your settings through Settings → System system → Backup.

❓ Can I use the regimen constantly?

Technically yes, but not recommended: Long-term work in Extreme Performance reduces battery life (degradation by 10-15% faster); on devices with a weak cooling system (for example, Redmi Note 10), this can overheat the chipset. Some applications (for example, banking) can block work on “overclocked” devices due to suspicions of rooting. The best option is to turn on the mode only for resource-intensive tasks (games, rendering, benchmarks), and use Balanced Mode at the rest of the time.
