Booster on Xiaomi: A Complete Guide to Use and Setup

The Booster utility on Xiaomi smartphones is a built-in performance optimization tool that helps clean RAM, speed up application launches and improve the experience in games. Many users do not even know it exists, although the feature is available on most devices running MIUI (starting with version 12). Unlike third-party cleaners, Booster is integrated into the system and does not require additional programs to install.

The main purpose of the utility is to free up the resources of the phone in one click when the device starts to “brake.” But Booster’s capabilities are broader: it can optimize the performance of specific applications, speed up game loading and even extend battery life. However, not all functions are enabled by default, and some require manual adjustment. In this article, we will discuss how to use Booster on Xiaomi, what modes it supports, and how to avoid common errors in its use.

What is Booster on Xiaomi and why is it necessary?

Booster (or "Accelerator" in Russian localization MIUI) is a system utility that combines several tools to optimize the performance of a smartphone. It appeared as a response to users' complaints about slowing down devices over time. Unlike the classic cache cleaning, Booster works at a deeper level:

• 🧹 Cleaning RAM – closes the background processes, freeing up memory for current tasks.
• ⚡ Accelerate Games – Optimizes performance for running games (e.g, PUBG Mobile or Genshin Impact).
• 🔄 Optimizing applications – analyzes frequently used programs and speeds up their launch.
• 🔋 Charge savings – restricts background activity to extend battery life.

It’s important to understand that Booster isn’t a magic wand: it won’t increase the performance of a weak processor or add RAM. However, on mid-range and premium devices (such as the Xiaomi 13 Pro or Redmi Note 12 Pro+), the effect will be noticeable – especially if the phone is actively used (many apps, games, multi-tasking).

⚠️ Note: On some Xiaomi models (e.g, POCO F5 or Redmi K60) Booster can be hidden in the Settings menu → Special facilities → If it's not on the main menu, check this path.

How to Enable and Run Booster on Xiaomi

Booster activation depends on the MIUI version and the smartphone model. In most cases, the utility is available through the notification panel or system settings.

1. Open the notification panel (swipe your finger from top to bottom).
2. Click on the Cleanup icon (usually arrows in a circle or broomstick). If it is not, go to Settings → Apps → Cleanup.
3. In the window that opens, you'll see the "Speed" button (or "Booster" in English firmware).
4. Wait until the process is complete (usually 5-10 seconds) and the system will show how much memory has been released.

On some devices (such as the Xiaomi 12T or Redmi Note 11 Pro), the Booster can be integrated into the Security Center, in which case the path will be: Settings → Security Center → Accelerator.

If nothing happens after you click on "Speed Up", check:

• 🔌 Is the battery enough (less than 15% can block the function).
• 📱 Does the phone overheat (at a temperature above 45)°C Booster shuts down automatically).
• 🔄 Does the system update work in the background.

Booster modes: which to choose

Booster on Xiaomi supports several optimization modes, each suitable for different scenarios, which can be configured manually or let the system choose automatically.

To change the regime:

1. Go to Settings → Battery and Performance → Performance Modes.
2. Select the profile you want (e.g., “Performance” for games).
3. Press "Apply."

⚠️ Warning: Performance mode can cause overheating on devices with Snapdragon processors 7xx Dimensity 900 (e.g. Redmi Note 10 Pro) POCO X4 Pro) Use it only when the charger is connected.

Optimizing Games with Booster

One of Booster’s key benefits is improved gaming performance, and Game Turbo is automatically activated when supported applications (such as Free Fire or Apex Legends Mobile) are launched, but can be manually configured:

How to turn on Game Turbo:

1. Open Settings → Special Opportunities → Game Turbo.
2. Activate the switch at the top of the screen.
3. Add games to the list of "Optimized" (click "Add games" and select the desired ones).

The Game Turbo menu has additional settings:

• 🎮 Block notifications – disables pop-ups during play.
• 📶 Network optimization – prioritizes traffic for the game (good for online shooters).
• 🔊 Amplifies sound – improves the perception of sound effects.
• 🖱️ Tactile recoil - adjusts the vibration to a specific game.

💡

If the game does not support Game Turbo by default, add it manually through Settings. → Annexes → Application management → [Name of game] → Game turbo.

On devices with a Snapdragon 8 Gen 2 processor (such as the Xiaomi 13 Ultra), the Game Turbo can automatically increase the GPU clock speed by 10-15% when the charger is connected, which increases FPS in demanding games, but increases heat.

Common mistakes when using Booster

Despite its simplicity, many users make mistakes that nullify Booster’s effectiveness, and the most common ones are:

1. Over-cleaning of RAM: Some users run Booster every 10 minutes, believing it will speed up the phone. In fact, MIUI itself manages memory, and forced cleaning can slow down the re-launch of applications.
2. Using Performance 24/7. This mode is useful for gaming, but in everyday tasks it only drains the battery faster and heats the processor.
3. Ignoring updates. Booster works more efficiently on the latest versions of MIUI. If you haven't updated the system for a long time, some features may not work.
4. Background optimization is disabled. In the battery settings, there is an option called Background Activity Optimization, which prevents Booster from properly managing processes.

⚠️ Attention: On devices with MIUI 14 and later forced cleaning of RAM via Booster may conflict with the function "Advanced memory" (virtual) RAM). If after cleaning the phone starts to "lay down", turn off virtual memory in Settings → Additionally. → Expanded memory.

How to check the effectiveness of Booster

To see if Booster is really improving performance, you can use built-in MIUI tools or third-party benchmarks.

• 📊 Performance Monitor: Go to Settings → The phone. → Status of the system → Performance monitor. This is the use of the CPU, GPU RAM before and after optimization.
• ⏱️ Start time: See how long it takes to open frequently used programs (such as Instagram or Chrome) before and after using Booster.
• 🎮 FPS In games: Enable the frame counter in the game settings or through Game Turbo (Show option) FPS). Compare the performance in the “Balanced” and “Performance” modes".
• 🔋 Battery life: Use the "charge saving" mode and track battery discharge through Settings → Battery → Battery utilization.

For more accurate measurements, third-party applications can be used:

• CPU Throttling Test – checks whether the system is limiting performance.

💡

The effect of Booster is most noticeable on devices with 6-8 GB of RAM. On phones with 12+ GB (for example, Xiaomi 14 Pro), the difference will be minimal due to the excess of memory.

Booster Alternatives: When to Use Third-Party Utilities

Although Booster coping will handle most tasks, alternative solutions may be needed in some cases:

Before installing third-party utilities, however, consider:

• 🛡️ Cleanup applications often contain ads or collect data.
• ⚙️ Some features (e.g., deep optimization) require root rights, which makes it impossible to guarantee the right to root.
• 🔄 Booster is already integrated into the system and does not conflict with the system. MIUI, unlike third-party programs.
