How to Enable Hidden Optimization Settings on Xiaomi: Full Guide 2026

Xiaomi's MIUI phones hide dozens of useful features under the hood that are disabled by default by the manufacturer, from developer mode to fine-tuning animations, these tools allow you to squeeze the most out of iron, even if your Redmi or POCO is not new. But how do you activate them without the risk of bricking the device?

In this article, we will look at step-by-step instructions with pictures, a list of safe tweaks to speed up the system and solve typical problems (hangs, overheating, fast battery discharge), we will analyze both standard optimization methods through Settings, and advanced ones using ADB and engineering menus, all recommendations tested on MIUI 14/15 and are relevant for models from 2020 to 2026.

⚠️ Important: some settings may result in a loss of warranty if you modify system files.All actions you perform at your own risk. 12T Pro, Redmi Note 12 and later) some features may be limited.

1. How to Enable Developer Mode on Xiaomi

Developer Mode is the back door to Android settings, where the tools for diagnosis, debugging and optimization are hidden. Without activating it, you can't:

• 🔧 Change the animation of the system (accelerate or disable)
• 📊 Include monitoring of CPU use/GPU
• 🔌 Unlock. USB Debugging for ADB
• 🎮 Accelerate the screen refresh rate (for example, up to 144 Hz on supported models)

To activate the regime:

1. Open the Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row (you will be notified "You became a developer!").
3. Return to the main Settings menu, and a new section for developers will appear.

Check the battery charge (minimum 30%|Connect to Wi-Fi (for downloading logs if necessary)|Remember the password from the Mi Account (required to unlock the bootloader)|Make a backup copy of important data-->

⚠️ Note: On some models (POCO F5, Xiaomi 13 Ultra) after activation of the developer mode may appear warning about “uncertified device” in Google Play. This is not critical – certification can be restored through Settings → Google → Certification of the device.

2. Top.-5 settings to optimize productivity

Once you activate the developer mode, you get access to settings that directly affect the speed of your smartphone. Here are the most effective and safe tweaks:

💡 Tip: If after the changes the smartphone began to overheat, return the settings Force GPU-rendering 4x MSAA These parameters put a lot of pressure on the Snapdragon or Mediatek processor.

3. FPS unlock and screen refresh rate

Many Xiaomi/POCO/Redmi models support high screen refresh rates (90Hz, 120Hz, 144Hz), but by default run at 60Hz to save battery life.

1. Go to Settings → Display → Update frequency.
2. Select Automatic or Maximum (e.g. 144Hz for POCO F4 GT).
3. For models with AMOLED-screens (Xiaomi 12 Pro, Redmi) K50 Pro) turn on Adaptive frequency – this will balance smoothness and autonomy.

⚠️ Note: On budget models (Redmi) 10A, POCO M4 Pro) forced on 90 Hz can lead to accelerated battery wear (up to 15-20% in 6-8 hours on standby mode).

For advanced users: If the menu does not have a 144Hz option, but you know that your display supports this frequency (for example, the POCO F3 GT), you can unlock it through ADB:

adb shell settings put global peak_refresh_rate 144


adb shell settings put global min_refresh_rate 144

4. MIUI optimization: disabling unnecessary services

MIUI is known for its abundance of background processes that eat up RAM and battery, and here's what you can safely turn off:

• 📱 Mi Cloud Sync (Settings) → Accounts. → Mi Cloud → Synchronization – if you don’t use backups in the cloud.
• 📊 Analytics MIUI (Settings → Confidentiality → Analytics MIUI) — sending data to Xiaomi.
• 🔊 Auto-Update Applications (Google Play) → Settings → Auto Update – Better to update manually.
• 📡 Dirac Audio Tuner (Settings) → Sound. → Equivalent – if you don’t use headphones.

For deep cleaning:

1. Install ADB AppControl (USB Debugging is required).
2. Disable system applications through it: com.miui.analytics (analytics) com.xiaomi.midrop (Mi Drop, if you do not use) com.miui.videoplayer (standard video player)

💡

Before disabling system applications, check them in Package Name Viewer (the app in Play Market).Some services (com.android.phone) are critical for the phone to work!

5 Problem Solving after Optimization

If after the changes, the smartphone began to behave unstable, use this instruction:

🔧 Critical case: if the smartphone stopped turning on after changes in the ADB, Try resetting your settings through Recovery Mode:

1. Turn off the phone.
2. Press the Power button + Volume up for 10 seconds.
3. In the recovery menu, select Wipe & Reset. → Wipe All Data.

💡

Before any manipulation of system files, back up via Settings → Additional → Backup and Reset. This will save your data if you crash.

6. Advanced Optimization through ADB

For users willing to go beyond standard settings, ADB (Android Debug Bridge) provides access to hidden commands.

• 🚀 Overclocking the processor (only for Snapdragon) 8 Gen 1/2): adb shell settings put global cpu_boost_enable 1 ⚠️ Risk: overheating and trottling (automatic frequency reduction).
• 🔄 Shutdown MIUI Optimization (removes restrictions on background processes): adb shell settings put global miui_optimization_disabled 1 ⚠️ Consequences: possible bugs with notifications.
• 📶 Compulsory incorporation VoLTE/VoWiFi: adb shell settings put global volte_enabled 1 adb shell settings put global wifi_calling_enabled 1

📌 Important: Teams ADB They are valid until the first reboot, and in order to keep the changes permanent, root rights are required (which voids the warranty).

To check the current settings, use the command:

adb shell settings list global | grep "miui\|cpu\|refresh"

7.Optimize for Games: Game Turbo and Hidden Chips

For gamers, Xiaomi offers a built-in Game Turbo, but its options are limited.

1. Open Settings → Special features → Game Turbo
2. Turn it on: 🎮 Performance mode (maximum performance) FPS) 🔇 Block notifications (to avoid distractions) 📶 Network Priority (reduces ping)

Snapdragon 8+ Gen 1

Xiaomi 13T Pro

POCO F5 Pro

GPU Driver: OpenGL ES

🔥 Secret Tweak: Some games (e.g. Genshin Impact, Call of Duty Mobile) can force 120 to play FPS, Even if the option is hidden:

1. Connect your phone to a PC with ADB.
2. Adb shell settings put global force_high_refresh_for_games 1

💡

Game Turbo works more effectively if you close all background applications through Settings → Applications → Clean before starting the game.
