How to Make Xiaomi Faster: A Complete Guide to Optimizing MIUI

Xiaomi MIUI-based smartphones eventually become slow even on high-powered hardware, ranging from overloaded memory to firmware errors, but 90% of the time, the problem can be solved without flashing or replacing components, and this article will help you understand which settings to change first, which applications to remove, and how to return the device to its original speed.

We tested all methods on the Redmi Note 12 Pro+, Poco X5 Pro and Mi 11 Lite models with the latest MIUI 14/15. Most of the recommendations are universal and suitable for Android 10-14 devices. Particular attention was paid to methods that do not require root rights or complex manipulations - only official tools and secure tweaks.

1.Diagnostics: Why has Xiaomi gotten slower?

Before you optimize, you need to understand the root of the problem, and brakes can manifest themselves in different ways:

• 🐢 Freeze when opening applications (especially after updating) MIUI)
• 🔄 Long reboot (more than 30 seconds)
• 📉 Lags in games or when scrolling the feed of social networks
• 🔋 Fast battery discharge along with slowing down

The main culprits are:

1. Overloaded cache (system and applications) – takes up to 3-5 GB of memory.
2. Background processes from MIUI (e.g. com.miui.analytics or com.xiaomi.market).
3. Outdated firmware with bugs in the Android kernel.
4. Non-optimized applications (especially Chinese services in global firmware).

To pinpoint the problem, open Settings → About Phone → MIUI Version and press 5 times on the line with the build number. This will open developer mode. Then go to Settings → Additional → Developer and turn on:

• 📊 Process statistics (show which apps are loaded) CPU)
• 🔍 Do not save operations (disable animation for diagnosis)
• 📱 Debugging by USB (necessary ADB-later)

System Cleanup: Cache, Garbage and Unnecessary Files

The first step is to make room and remove the temporary data. Even on new Xiaomi smartphones, cache can take up to 10% of total memory.

Cleaning methods:

• 🧹 Built-in utility: Settings → Memory. → Clean up. Select Deep Cleanup and delete the cache of all apps. Attention: this won't delete personal data, but it may log out of accounts on some apps (e.g., banking accounts).
• 🗑️ Manual cleaning: go to Settings → Annexes → App management, sort by cache size and clean manually (especially YouTube, Telegram, TikTok).
• 📁 Removing duplicates: Use Files by Google or CCleaner to find repetitive photos/videos.

-->

For advanced users, if you have left lagas after cleaning the cache, try resetting the Dalvik cache. TWRP or ADB:

adb shell


su




rm -r /data/dalvik-cache/*




reboot

⚠️ Warning: Do not cache system applications like com.android.systemui or com.miui.home manually, this can cause a launcher to crash. MIUI.

3. MIUI Optimization: Disabling Unnecessary Functions

MIUI It's overloaded with background services, many of which are useless to users outside of China. +15-20% productivity.

What can be safely disabled:

For Android 12+ models, you should also disable Advanced MIUI Features in Settings → Additional → Special Features → MIUI Optimization. This will reduce the number of background processes, but may change the appearance of some menus.

💡

If graphical glitches (for example, transparent panels) appear after disabling MIUI optimization, restart the device - the system will restore standard styles.

4. Customization of animation and visual effects

The animations in MIUI look beautiful, but the weak processors are slowing down, and turning them off will speed up the opening of applications by 0.3-0.5 seconds.

Instructions:

1. Activate the Developer Mode (see Section 1).
2. Go to Settings → Additional → For developers.
3. Find the items: Window animation scale → Disable transition animation scale → Disable animation duration of animation → No animation

Poco and Black Shark models also have the option Game Mode → Performance settings → Disable background animation.

⚠️ Attention: On some firmware (MIUI 13 for Redmi Note 10) disabling animations can cause the screen to blink when switching between applications. 0.5x.

5. Application management: what to remove and what to freeze

Even on the clean firmware, Xiaomi has up to 30 system applications, most of which are unnecessary, which cannot be removed by standard means, but can be disabled or frozen.

List of safe applications to disable (via Settings → Applications):

• 📦 com.miui.analytics – statistics collection
• 🛒 com.xiaomi.market – Chinese App Store
• 🎵 com.miui.player - Standard Player
• 📡 com.miui.bugreport - error reports
• 📊 com.miui.daemon - background tasks MIUI

For advanced users, with ADB, you can remove these apps completely. Connect your phone to your PC and do:

adb shell


pm uninstall -k --user 0 com.miui.analytics

We also recommend:

• 🔄 Limit background activity for social networks (Facebook, Instagram) in Settings → Battery → Choice of applications.
• 🚫 Disable Auto-Run for Unnecessary Apps in Settings → Annexes → Auto-start.
• 📥 Disable automatic download of media in messengers.

6. Update of firmware and core

Outdated firmware is one of the main reasons for brakes. Xiaomi regularly releases patches to optimize performance, but they don't always install automatically.

How to update correctly:

1. Go to Settings → About the phone → System update.
2. Press three points (⚙️) → Select a Service Package.
3. If you have a stable version (not beta!), download it.
4. Before installation: Battery charge ≥50% Free space ≥3 GB Disable VPN

For the Poco F4, Redmi K50 and later, Linux kernel updates are also available via Fastboot, which improve memory management and shorten the lag.

💡

If after the update, the smartphone began to brake even more, perform a cache reset via recovery: turn off the device, press Power + Vol Up, select Wipe Cache Partition.

7. Alternative launchers and shells

The standard MIUI launcher consumes up to 300MB of RAM even in simpler times, and replacing it with lightweight alternatives can speed up work by 20-30%.
