How to Make Xiaomi Faster: A Complete Guide to Optimization

Does your Xiaomi slow down after the upgrade? Does it take too long to open apps, does it slow down animations, and does it take half a day to run out of battery? The problem isn't with the ageing of the iron -- 90 percent of the time, cache, background processes, and suboptimal MIUI settings are to blame. Even budget models like the Redmi Note 12 or POCO X5 can fly if you set them up properly.

In this article, 12 proven ways to speed up Xiaomi, from basic (clean up garbage) to advanced (disable system services via ADB), we will analyze which settings really affect performance and which are myths, all methods tested on current versions of MIUI 14/15 and HyperOS (2026).

Spoiler: You don't need root rights or complex manipulations -- most tricks work out of the box. But if you're willing to dive deeper, there's a section at the end of this article for power users with ADB commands and hidden features.

1.Diagnostics: Why Xiaomi is slowing down?

Before you optimize, you need to understand the source of the brakes. Xiaomi has a built-in diagnostic tool — Safety → Acceleration. Here the system will show:

• 📱 CPU load (if continuously above 70% – background processes eat up resources)
• 🗑️ Occupied storage (if less than 10% of the free space, the smartphone will lie down)
• 🔋 Battery consumption (if a process is consuming >20%, it must be turned off)
• 🌡️ Overheating (at temperatures above 45°C, processor trolls)

Typical causes of brakes:

A critical mistake many users make: they immediately reset the smartphone to factory settings without checking simple solutions. In 60% of cases, it is enough to clear the cache and disable 2-3 unnecessary functions to return smoothness.

⚠️ Warning: If the brakes are coming in after a fall or moisture hit, it's a hardware problem. No optimization is going to help, you need a diagnostic at the service center.

2. Cleaning the system: remove garbage and cache

The first thing you need to do is to make room and delete temporary files. MIUI has a built-in Cleanup tool, but it doesn't delete everything. Here's the full instructions:

1. App cache cleanup: 📱 Go to Settings → Applications → App management 🔍 Sort by cache size (click three dots in the top right corner) 🧹 Remove cache from apps with a volume of >500 MB (especially messengers and social networks)
2. Delete Unnecessary Files: 🗑️ Go to Files → Categories → Multimedia 🎵 Delete duplicate photos/video (use the built-in Duplicate Finder tool) 📂 Clear Download folder – unnecessary APK and archives often accumulate here.

Storage optimization:

• 📊 In Settings → Storage Press Clean (the system will find garbage)
• 🔄 Enable Autoclean (remove cache once a week)

Once cleaned, reboot your smartphone, the system will reassemble the Dalvik cache, and the work will be smoother. If there is less than 5 GB of free space, consider transferring files to microSD (but not all, but only photos / videos / music).

⚠️ Warning: Don't use Play Market cleaners (like Clean Master or CCleaner) that not only don't help, but can increase the brakes by triggering background processes to "monitor."

3. MIUI Optimization: Hidden Settings for Speed

MIUI and HyperOS have a lot of hidden features that affect performance, and most users don't even know they exist.

• ⚡ Performance Mode: Go to Settings → Special Features → Performance Mode Enable High Performance (increase CPU clock speed) ⚠️ Battery will go down faster, but FPS in games will grow by 15-20%
• 🔄 Animation and transitions: Enable Settings → About Phone → Version MIUI (click 7 times to activate Developer Mode) Go to Settings → Additional → For developers Set Windows Animation Scale, Transition Animation Scale, and Animator Duration Scale on 0.5x or Off.
• 📶 Background activity restriction: In Settings → Battery → Select Battery Mode Select Balance or Performance For individual applications (e.g. Facebook) Set Limit Background Activity

Another secret: MIUI 14+ has a Deep Optimization feature that automatically closes down unused processes.

Settings → Memory → Deep Optimization → Enable

But be careful: if you turn on this feature for instant messengers (like Telegram or WhatsApp), notifications may come with a delay.

4. Disabling unnecessary functions and services

Xiaomi likes to "improve" the user experience by adding a bunch of background services, many of which are unnecessary but constantly consuming resources.

It is also necessary to prohibit the auto-launch of unnecessary applications:

1. Go to Settings → Applications → Application Management → Autorun
2. Turn off auto-runs for social media, games, and other rarely used programs
3. For critical applications (messengers, banks) leave autorun on

⚠️ Warning: Don't turn off system services like Google Play Services or Miui Daemon, which will cause critical malfunctions in your smartphone.

💡

If you're not sure if you need a feature, turn it off for a day and check if the smartphone is stable. Most of the improvements from Xiaomi can be returned at any time.

5. Updating firmware: when it helps and when it hurts

Many users believe that the MIUI update will automatically speed up the smartphone, which is not always the case.

• ✅ You need to update if: 🐞 The current version has critical bugs (e.g., call lags) 🔒 Security patches (especially if you use mobile banking) 🚀 The changelog mentions "performance optimization"
• ❌ Do not upgrade if: 📉 You have an old model (e.g. Redmi Note 8) and an update is for new devices 🔋 After the last update, the battery started to go down faster 📡 You have unstable Internet (an interrupted update can "brick" the smartphone)

How to properly update:

1. Backup important data (photos, contacts) through Settings → Additional → Backup
2. Connect to a stable Wi-Fi network (not mobile internet!)
3. Charge the battery by at least 50%
4. Update through Settings → About Phone → System Update, Not Through Third-Party Firmware

If after the update, the smartphone began to work worse:

• Wait 12-24 hours – the system is optimized in the background
• Reset the cache through Settings → Storage → Clear the cache
• If the lags are left, reset to factory settings (but this is an extreme measure!)

6 Advanced Methods: ADB and Hidden Commands

If the basics didn't work, it's time to move to advanced optimization, which requires PC connectivity and ADB commands, but maximizes performance.

Important: Before working with ADB:

• Enable USB Debugging in Settings → For Developers
• Install Xiaomi drivers on PC (download from the official website)
• Use the original USB- cable (cheap may not transmit data)

Acceleration commands (enter Command Prompt or Terminal):

adb shell settings put global hidden_api_policy 1 # Unlocks hidden API


adb shell settings put global window_animation_scale 0.5 # Accelerates window animation




adb shell settings put global transition_animation_scale 0.5 # Accelerates transitions




adb shell settings put global animator_duration_scale 0.5 # Accelerates animation




adb shell pm disable-user --user 0 com.miui.analytics # Disables Xiaomi Analytics




adb shell pm disable-user --user 0 com.xiaomi.ab # Disables advertising services

To disable unnecessary system applications (without root):

adb shell pm uninstall -k --user 0 com.miui.videoplayer # Videoplayer


adb shell pm uninstall -k --user 0 com.miui.player # Music player




adb shell pm uninstall -k --user 0 com.xiaomi.scanner # Document scanner




adb shell pm uninstall -k --user 0 com.miui.bugreport # Error Reports

⚠️ Warning: Don’t disable system services like com.android.phone or com.miui.home, this will cause your smartphone to fail!

After completing the commands, restart your smartphone. The effect will be noticeable immediately: applications open faster, the hangings disappear when scrolling, and the battery lasts longer.

💡

ADB- commands give performance gains at 20-30%, but require caution. Always check what you turn off and back up before changing.

7 Hardware Limitations: When Optimization Will Not Help

If your Xiaomi is older than 2018 (like the Redmi Note 5 or Mi A1), even the deepest optimization won’t bring it back to its former smoothness.

• 🔋 Worn-out battery: If the capacity has dropped below 70%, the processor will trottle even at 30% charge
• 🖥️ Weak CPU: Snapdragon 625/636 won't physically pull on modern applications
• 🧠 Little RAM: 2-3 GB of RAM is not enough for MIUI 14+
• 💾 Slow memory: eMMC 5.1 is 3-5 times slower than UFS 2.2 in new models

In such cases, consider:

• 🔄 Downgraid firmware: get back on MIUI 11/12 They work faster and easier on the old iron.
• 📱 Custom firmware installation: LineageOS or Pixel Experience will give a second life to the device
• 💰 Upgrade: If budget allows, consider models with Snapdragon 7+ Gen 2 or Dimensity 9000+

Critical: If the smartphone overheats even for simple tasks (such as calls) - it is a sign of wear and tear of the thermal paste or degradation of the processor, in which case only repair will help.

8. Alternative firmware: should you switch?

If standard methods don't work, some users look at custom firmware.

• ✅ Clean Android without unnecessary Xiaomi services
• ✅ More frequent security updates
• ✅ Ability to fine-tune performance

But there are downsides:

• ❌ Loss of guarantee
• ❌ Risk of "bricking" a device if the firmware is incorrect
• ❌ Possible bugs with camera, NFC or sensors

Popular firmware for Xiaomi:

If you decide to use custom firmware:

1. Make a full backup through TWRP
2. Unlock the bootloader (instructions on the official Xiaomi website)
3. Install OrangeFox Recovery or TWRP
4. Sweep through firmware and GApps (if you need Google services)

⚠️ Warning: On models with Dynamic RAM Expansion, custom firmware may not work smoothly. Check compatibility on the XDA Developers forum before installing.
