What it means to optimize Xiaomi phone: a complete guide to improving the performance of the smartphone

When you hear the phrase “optimize Xiaomi phone,” it’s not about the magic button that will instantly turn your smartphone into a supercomputer, it’s a set of measures designed to improve performance, increase battery life and free up memory. Unlike other brands, Xiaomi phones (especially MIUI-based ones) have unique features, from branded services to hidden settings that can be fine-tuned to their needs.

But what exactly is meant by optimization? For some, it's removing unnecessary applications, for others, setting the CPU background, and for others, fighting overheating. In this article, we'll look at all the key aspects, from basic actions that beginners can do to advanced tricks for power users. It's important to understand that optimization is not a one-time action, but a regular process, especially if you're actively using your smartphone for games, multimedia or work.

Before you start, ask yourself, what exactly is it that's bothering you about your phone? Slow app loading? Fast battery drain? Memory shortage? Which will determine which settings to pay attention to. And remember, not all tips are universal — what helped on the Redmi Note 12 may not be useful for the POCO F5.

1.What is the concept of “Xiaomi phone optimization”?

Optimization usually refers to three key areas:

• 🔋 Performance: acceleration of the system, reduction of lags, correct operation of background processes.
• 📱 Memory: Freeing internal storage and RAM from garbage.
• 🔄 Autonomy: setting up the battery for maximum non-recharging time.

However, in practice, optimization can affect other aspects:

• 🌡️ Temperature: Fighting overheating is especially relevant for gaming smartphones (Black Shark, POCO F).
• 🛡️ Security: Removing malware, setting permissions for applications.
• 🔊 Multimedia: improving sound quality, setting up screen animations.

It's important to distinguish between reset and factory settings, the latter being a radical measure that erases all data and returns the phone to the "out of the box" state, while optimization involves spot changes without losing personal information, such as turning off autoloading unnecessary apps or setting up performance mode in Settings → Battery.

⚠️ Note: Some Google Play “optimizers” promise miraculous acceleration, but in fact only load the system with additional processes. MIUI — Additional software is not usually required.

2. Basic optimization: where to start?

If you’ve never set up your phone before, start with simple steps:

1. App cache clearing. Cache speeds up programs, but over time takes up gigabytes of memory. Go to Settings → Apps → Application Management, select any one and click Clear Cache.
2. Use the built-in Cleaner (Security → Cleanup) or file manager to find large and old files.
3. Disable AutoRun. Many applications start when you turn on your phone and run in the background. Turn them off in Settings → Permissions → AutoRun.

It’s also worth checking the installed app list. Users are often surprised to find dozens of Xiaomi pre-installed services (e.g. Mi Video, Mi Music) that have never been used, and can be disabled (but not removed entirely) through the same App Management section.

Another simple but effective trick is to reboot your phone every 2-3 days, which clears RAM and shuts down the “hang” processes, especially for models with 4-6 GB of RAM (Redmi 9A, POCO M3).

💡

Turn on Auto Clean in Settings → Battery → Battery Settings. It automatically closes the background apps when the charge drops below 15%.

3. Performance Optimization: How to Speed Up the Phone?

If the phone starts to slow down, the reasons can be different, from overloaded memory to malfunctioning firmware.

• 🔄 Update. MIUI to the latest version. Go to Settings → The phone. → System update: Newer versions often contain patches for lags.
• 🎮 Turn on performance mode. Settings are appropriate for games. → Special facilities → Game mode (available on POCO and Black Shark).
• 🧹 Limit background activity. In Settings → Battery → Battery management select applications and set background limit.

For advanced users, there are hidden settings:

Enter the phone app: ##4636##


Go to the Battery Information section and see usage statistics.




In the section "Usage Statistics" you can see which processes load the system.

If the lags appear when you run specific apps (such as Instagram or PUBG Mobile), try:

• Clear the cache and application data.
• Turn off animations in Settings → About Phone → MIUI version (click 7 times on the version to turn on Developer Mode, then in Settings → Additional → For developers, set the window animation scale to 0.5x).

⚠️ Warning: Turning off animations will speed up the interface but make it less smooth. -- on weak phones (Redmi) 8A) This can lead to screen blinking.

Battery Optimization: How to Extend Your Lifetime?

The battery is one of Xiaomi’s most vulnerable smartphones, and even newer models (Xiaomi 13, Redmi Note 12 Pro+) can run out of power in a day when used actively.

One of the most effective ways is to calibrate the battery.

1. Discharge the phone to 0% and turn it off.
2. Connect to charging and wait 100% without turning on.
3. Turn off the charging, turn on the phone and recharge to 100%.

Critical information: On Xiaomi phones with a battery capacity of 5000 mAh and above (for example, POCO M5, Redmi 10C), a full discharge-charging cycle is recommended every 2-3 months.

Turn off "Adaptive Brightness" in the screen settings

Turn off "Device Search" in Google Settings

Set background restrictions for social networks (Facebook, TikTok)

Turn on "Energy saving" manually at 20% charge

5. Memory cleansing: how to make room?

Lack of memory is one of the main reasons for lags. Even if you have Xiaomi with 128 GB or 256 GB, the system gets clogged with garbage over time.

• 📁 Delete duplicate photos. Use the built-in Gallery app. → Management → Duplicate.
• 🎵 Transfer music and video to the memory card (if supported). → Storage select Data Transfer.
• 🗑️ Clean up downloads.The Download folder often contains gigabytes of unnecessary files.
• 🌐 Clear the browser cache. In Chrome or Mi Browser, go to Settings → History → Clear the data.

For deep cleaning, use Settings → Storage → Cleaning. Here you can delete:

• Cash of applications;
• Temporary update files;
• Unused. APK-file.

If internal memory is critically lacking, consider linking the memory card as internal storage (available on Android 9 and below).

⚠️ Note: Do not use applications like Clean Master or CCleaner – they often delete important system files, which leads to crashes. MIUI All the necessary tools are already in place.

6. Advanced methods: for experienced users

If the basic methods didn't work, you can try deeper settings, and be careful, if you do something wrong, you can crash the system.

• 🔧 Shutdown MIUI-Some system processes (e.g., mipush, analytics) can be disabled via ADB: adb shell pm uninstall -k --user 0 com.xiaomi.mipush This will remove the services only for your user without affecting the system.
• 📉 Undervolting processor to reduce heat requires unlocked bootloader and custom core.
• 🔄 Installing custom firmware (like LineageOS or Pixel Experience) is a radical step, but can speed up older models (Redmi Note 5, Mi) much faster. A2).

For owners of phones with AMOLED-screens (Xiaomi 12, POCO F4) It is useful to turn on the dark theme and turn off the Always on display (AOD). This will reduce battery consumption by 10-15%.

💡

Before any system manipulations (ADB, firmware) make a backup through Settings → Additional → Backup and Reset.

7. Optimization for Specific Xiaomi Models

Some Xiaomi phones have unique features that are worth considering:

For gaming phones (Black Shark 4, POCO F3 GT) it is useful to:

• Activate the game mode in the settings;
• Connect an external gamepad to reduce the load on the screen;
• Use a cooling stand.
