How to Optimize Xiaomi: A Complete Guide to Acceleration and Customization MIUI

Xiaomi smartphones based on firmware MIUI They're known for their rich functionality, but over time, even the most productive models start to slow down, and the reasons range from overloaded memory to background processes that eat up resources. This article is not about radical measures like factory resets, but about system optimization – how to return the device to performance without losing data.

We will analyze both basic settings (cleaning cache, managing autoload) and advanced tricks (turning off telemetry, fine-tuning animations). All recommendations are tested on models from Redmi Note 10 Pro to Xiaomi 14 Ultra and are relevant for the future. MIUI 12-14 If your smartphone is slower after the upgrade, here’s the solution.

Important: optimization doesn't require root rights, but some things will require care, such as disabling system applications through the use of a computer. ADB This can lead to unstable operation of Xiaomi services (for example, Mi Cloud or theme store.

1.Diagnostics: Why Xiaomi is slowing down?

Before you optimize, you need to understand the root of the problem. 80% of the time, lag is caused by:

• 📱 Overloaded memory – less than 1 GB of free space on the system partition.
• 🔄 Background processes — MIUI aggressively caches applications, even those that have not been used for a long time.
• 📊 Telemetry and analytics – Xiaomi collects usage data that loads CPU.
• 🎨 Animations and visual effects – beautiful, but resource-intensive.

To check the current state:

1. Open Settings → About the phone → System status.
2. Check the usage schedules CPU, RAM and memory.
3. If you see applications with consumption in the Battery section >5% in the background – you need to limit them.

⚠️ Note: If you see com.miui.analytics or com.xiaomi.midrop in System Processes, it is a sign that telemetry is in the background).

Memory Cleanup: What Can Be Deleted Without Risk

MIUI It creates a cache to make things faster, but over time it turns into digital garbage.

Start with safe methods:

• 🧹 App cache: Settings → Annexes → Application management → [select] → Warehouse → Clear cache. For system applications (such as Gallery or Music) it is safe.
• 🗑️ Unnecessary APK: Download often leaves installation files of older versions of applications in the folder.
• 📁 Duplicate photos: Use the built-in tool for searching for duplicates (Albums) → Smart albums. → Duplicate).

For deep cleaning:

1. Install Files by Google from Play Market – it finds temporary files that are MIUI doesn't.
2. Manually check the folders: /storage/emulated/0/Android/data/ — herein stored application data /storage/emulated/0/MIUI/ — cache of themes and wallpaper /storage/emulated/0/Download/ — load

⚠️ Note: Do not delete files from folders /system or /vendor — It'll cause a breakdown. MIUI. Also, don’t touch files with the.odex or.vdex extension – they are critical for Android.

3. Optimization of autoboot and background processes

MIUI By default, it allows most applications to start when the system starts and run in the background. It kills the battery and slows down the interface.

How to limit:

1. Turn off autostart: Settings → Annexes → Application management → [select] → Auto-run For social networks (Facebook, Instagram) and instant messengers (Telegram, WhatsApp) auto-run can be left, but for games and rarely used programs – turn off.
2. Limit background activity: Settings → Battery and productivity → Battery management → Choice of applications → [choose] → Background activity → Limit
3. Freeze system applications (advanced only): Use ADB-Command: Adb shell pm disable-user --user 0 com.miui.analytics Complete list of safe packets to disable: List of system packages MIUI to disable com.miui.analytics — telemetry com.xiaomi.midrop — Mi Drop (file sharing) com.miui.bugreport — sending error reports com.miui.cloudservice — backup Mi Cloud (if not used) com.miui.yellowpage — Yellow Pages (not relevant for Russia)

Once you turn off the autoboot, some apps will be able to open longer when you first start up -- that's OK, but it'll be more responsive.

💡

Disabling auto-runs for 10 to 15 unnecessary applications can increase battery life by 15 to 20 percent and speed up multitasking.

4.Set up MIUI for maximum performance

MIUI It offers hidden options for fine optimization. Here's what you can do without root:

Disabling animations (accelerates transitions between screens):

1. Activate Developer Mode: Settings → About Phone → MIUI Version (click 7 times)
2. Back to Settings → Additionally. → For developers and set: The scale of the animation window: 0.5x Scale of transition animation: 0.5x Duration of the animator: 0.5x

Switching to high-performance mode:

• 🔋 B Settings → Battery → Battery mode select Performance (instead of Balanced or Charge Saving).
• 🎮 For games: in Settings → Special facilities → Game Turbo Enable High Performance and Disable Framerate Optimization (if the game supports high performance) FPS).

Optimization of screen resolutions:

In the models with AMOLED-screens (e.g. Xiaomi) 13T Pro) you can save resources by reducing the resolution:

Settings → Display → Screen resolution → FHD+ (2400×1080)

The difference in quality is minimal, and the performance gain in games and when scrolling the interface is up to 10%.

💡

If the fonts become too small after changing the resolution, go back to Settings. → Display. → Scale of text and increase the size by 10-15%.

5. Update Management: When and How to Update MIUI

Updates MIUI subdivided:

• 🔄 Weekly betas are for enthusiasts, but often contain bugs.
• 📦 Stable updates - verified versions, come out every 1-2 months.
• 🛠️ Security patches for Android are coming out monthly.

Recommendations for updating:

How to update safely:

1. Before upgrading, check the free space - you need a minimum of 3 GB on the system partition.
2. Connect to Wi-Fi (updates weigh 1-2 GB).
3. The battery should be charged. >50%.
4. If the update weighs >1.5GB, back up through Settings → Additionally. → Backup.

⚠️ Note: If after the update Xiaomi began to overheat or discharge quickly, reset the cache through Settings → The phone. → Updating the system → Three dots (menu) → Clear the update cache.This will delete temporary files without affecting user data.

6. Alternative firmware: when to switch to caste

If optimization MIUI It didn't help, look at alternative firmware:

• ⚡ Pure Android without Xiaomi telemetry (e.g. Pixel Experience).
• 🔄 More frequent updates (e.g. LineageOS supports devices longer than Xiaomi).
• 🎨 Flexible configuration (e.g. Havoc-OS allows you to finely configure the kernel).

Cons:

• ❌ Loss of warranty (if unlocking the bootloader).
• ❌ Risk of "bricking" with incorrect installation.
• ❌ Certain functions (e.g, IR-blaster NFC) They may work unstablely.

If you do, follow this algorithm:

1. Unlock the bootloader through the official Xiaomi tool (you need a Mi Account).
2. Install TWRP Recovery for your model (see instructions on XDA Developers).
3. Download the firmware (e.g. Pixel Experience for Redmi Note 11 here).
4. Sweat through TWRP, having made a full backup.

⚠️ Note: On models with MediaTek (e.g. Redmi) 10C) Unlocking the bootloader may not be possible due to manufacturer policy.Before you start, check your device's support on the forums.

7.Optimization for Games: How to Make the Most FPS

Xiaomi with Snapdragon processors 8 Gen 2/3 (Xiaomi 13/14 series) capable of issuing 120+ FPS in games, but MIUI It's the default limit on performance. Here's how to break the limit:

Game Turbo settings:

• 🎮 Open the Settings. → Special facilities → Game Turbo.
• 🔧 Enable High Performance and Turn Off Framerate Optimization.
• 📊 In the Graphics Settings section, select Max for your game.

Manual setting GPU (requires rooting ADB):

adb shell settings put global force_high_performance true


adb shell settings put global gpu_driver_version 660

These teams are pushing maximum productivity. GPU. After application, restart the device.

Cooling:

Overheating leads to trottling (automatic performance decline) to avoid:

• 🧊 Use a cooling stand (e.g. Black Shark FunCooler Pro).
• 🔋 Play with the battery charge 40–80% (upon 100% or <15% heater).
• ☁️ Turn on air conditioning or fan – ambient temperature above 28°C worsens cooling.
