optimization MIUI

In this article, we will discuss all the available ways to disable optimization. MIUI Redmi Note 8 Pro – from standard settings to advanced methods ADB You will learn what restrictions prevent your smartphone from working at full capacity, and how to remove them without risk to the system.

It’s important to understand that a complete optimisation shutdown can affect the autonomy of the device. However, for most users, the gains in performance and convenience outweigh the marginal increases in battery consumption. If you’re willing to sacrifice 5 to 10 percent of your charge for the sake of stable application performance, this is the guide for you.

All methods tested on Redmi Note 8 Pro with firmware MIUI 12–14 (including global and Chinese versions) If you have a different model from Xiaomi or POCO, Some of the methods may also work, but there are no guarantees - the interface and available options may differ.

Why? MIUI So aggressively optimizing the system?

Smartphone makers including Xiaomi are actively using background optimization to extend battery life. On the Redmi Note 8 Pro, this is especially evident due to two factors:

• 🔋 4500 mAh battery is capacious, but not infinite. MIUI Trying to stretch it all day, severely limiting the background processes.
• 📱 MediaTek Helio processor G90T — It's powerful, but it's not the most energy efficient, and it's forced to reduce its frequency to avoid overheating and rapid discharge.
• 🤖 Android 9-11 (depending on version) MIUI) — older versions of the OS are less optimized for multitasking, so MIUI takes control.

As a result, users face typical problems:

⚠️ Note: If you notice that WhatsApp or Telegram are not showing notifications, and YouTube Music or Spotify stop playing music after 5 minutes after blocking the screen – it is the optimization that is to blame. MIUI. The system kills background processes, considering them “unnecessary".

Besides, MIUI limit:

• 🔄 Auto-Run Applications – Many programs cannot start on their own after a reboot.
• ⚡ Productivity CPU/GPU — In games and benchmarks, the smartphone is slower than it could be.
• 📶 Background Internet – applications lose communication with servers if the screen is turned off.

The irony is that on the Redmi Note 8 Pro with its 8GB of RAM and powerful chipset, these limitations are often excessive. MIUI artificially castrate".

Method 1: Disabling optimization through standard MIUI settings

So to start with the simplest method, it doesn't require root rights or a PC connection. MIUI There are hidden settings that allow you to relax the restrictions for individual applications.

Step 1: Allow auto-run for critical applications

1. Open Settings → Applications → Application Management.
2. Select the application you want (such as Telegram).
3. Slip on Autostart and switch on the switch.
4. Go back and press the permissions. → Additionally. → Show pop-up windows (for notifications).

Step 2: Turn off battery optimization

1. Go to Settings → Battery and Performance → Battery Consumption Management.
2. Select No restrictions for applications that must work in the background (messengers, music players).
3. For games (e.g, PUBG Mobile or Genshin Impact: Select High Performance.

Step 3: Set up "Memory Protection" (Hidden Function)

1. Open Settings → About phone and tap 7 times on the MIUI version to activate the developer mode.
2. Back to Settings → Additionally. → For developers.
3. Find Memory Protection and select Without Limits.

These settings will help to mitigate the restrictions, but will not remove them completely. MIUI It will still shut down the background if it sees fit, and a radical solution will require more in-depth methods.

Method 2: Using ADB to Deeply Disable Optimization

If the standard settings did not give the desired result, you can go further – disable optimization via Android Debug Bridge (ADB). This method does not require root rights, but will require connecting the smartphone to the computer.

What you need:

• 🖥️ Computer with Windows, macOS or Linux.
• 🔌 USB-cable (preferably original).
• 📦 Installed drivers Xiaomi and ADB Tools.

Step 1. Enable debugging over USB

1. Activate the Developer Mode (as in Method 1).
2. Go to Settings → Additional → For developers.
3. Turn on USB debugging and confirm the permission.

Step 2: Connect your smartphone to your PC and execute commands

1. Open the command prompt (cmd on Windows or Terminal on macOS/Linux).
2. Enter in turn: adb devices (should appear serial number device) adb shell settings put global hidden_api_policy 1 settings put global hidden_api_policy_pre_p_apps 1 settings put global hidden_api_policy_p_apps 1

Step 3: Turn off optimization for all applications

1. Follow the command: cmd package bg-dexopt-job (this will disable the background de-optimization of applications).
2. To disable background work restrictions: settings put global background_check 0

💡

If the apps still close after the commands are executed, try restarting the smartphone. Some changes only take effect after the reboot.

Important: Teams ADB Reset after resetting settings or updating MIUI. They'll have to do it again.

Method 3: Root access and complete optimisation disabling

If you are willing to take drastic measures, getting root rights will give you full control over optimization. MIUI. This method is suitable only for experienced users, as:

• 🔓 Violates the warranty (if it is still valid).
• 🛡️ Increases security risk (apps get access to system files).
• 🔄 Can lead to a "brick" (inoperability) of the device in case of errors.

Step 1. Unlock the bootloader

1. Go to the Mi Unlock website and download the official utility.
2. Link your Mi Account to your device in Settings → Xiaomi Account.
3. Launch the Mi Unlock Tool, connect the smartphone in Fastboot mode (clip Volume down) + Meals) and follow the instructions.

Step 2. Install custom recaveri (TWRP)

1. Download the current version TWRP Redmi Note 8 Pro (begonia model) from twrp.me.
2. Fastboot: fastboot flash recovery twrp.img fastboot boot twrp.img

Step 3: Get root with Magisk

1. Download the latest version of Magisk (Magisk-v26.4.zip or newer).
2. Reboot to TWRP and run the zip file.
3. Install Magisk Manager for root rights management.

Step 4: Disable optimization through system files

1. with the help of Root Explorer or ADB edit the file /system/build.prop:
2. Add the lines: ro.miui.optimize_props=false ro.miui.standby_bucket_mode=0
3. Remove or Freeze System Applications via Titanium Backup: 🚫 com.miui.powerkeeper (power management) 🚫 com.miui.securitycenter (security and optimization)

⚠️ Warning: Removing system applications can lead to unstable work MIUI. Before experimenting, make a backup through TWRP Or OrangeFox Recovery.
