How to speed up Xiaomi: a complete guide to optimizing your smartphone

Your Xiaomi is slowing down, apps are opening for a long time, and animation is twitching? These are typical signs of a clogged system or incorrect settings, POCO or Mi through 1-2 And in the years of operation, they're starting to work slower, because of background processes, outdated software and accumulated digital garbage. 90% In some cases, the problem can be solved independently. 10-30 minute.

In this article, we will discuss all possible ways of acceleration - from the basic (cleaning the cache, turning off animation) to advanced (kernel setting, optimization). MIUI The methods are suitable for devices on the MIUI 12-14 HyperOS, including Redmi Note models 10/11/12, POCO F3/F4/F5, Xiaomi 12/13/14 And we'll focus on the unique chips. MIUI, which slow down the system, but can be safely disabled without rooting.

1.Diagnostics: Why Xiaomi is slowing down?

Before you optimize, you need to understand the root of the problem, and Xiaomi often responds to slow work:

• 📱 Overloaded memory: Less than 10% of the free space on the internal drive leads to lags due to fragmentation of data.
• 🧹 Clogged cache: temporary application files and systems can take up to 5-10 GB by slowing down reading/write.
• 🔄 Background processes: MIUI aggressively keeps apps in place RAM, even if you don't use them.
• 🔄 Older versions: in older versions MIUI No optimizations for new apps (for example, Android 13)+).
• 🎮 Trojan settings: included transition effects, animation MIUI And the sound improvements eat up to 20% of the performance.

To determine the culprit, perform a quick check:

1. Open the Settings. → The phone. → Version. MIUI and press 5 times on the "Korea" - the developer mode will turn on.
2. Go back to Settings → More → For developers and find the item Processor Statistics.
3. Look at the loading schedule CPU: If it's constantly loaded at 50%+ without active tasks - a problem in the background.

If you download. CPU jumps chaoticly, and the phone warms for no reason - the background services are to blame (especially at the same time). POCO If the lags appear when you open specific applications (for example, Instagram or TikTok) – the problem is in the cache or conflict with the user. MIUI.

⚠️ Note: On Xiaomi models with Snapdragon processors 6xx/7xx (For example, Redmi Note 10 Pro) is a common bug with trottling, an artificial restriction on performance when heated. 5-10 minutes of the game, check the temperature in the application CPU Monitor.

2. Basic cleaning: cache, debris and unnecessary files

Let's start with the simplest thing, which is to delete temporary files. MIUI There's a built-in cleaning tool, but it only removes surface debris:

Clearing the application cache

• 📲 Go to Settings. → Annexes → Application management.
• 🔍 Sort by size (click on three dots in the upper right corner).
• 🧹 For each application >500MB press Storage → Clear the cache.
• 🚫 Do not clean up data (Clear everything) – this will delete accounts and settings!

Pay special attention to system applications: com.miui.home (launcher), com.android.systemui (interface), com.miui.securitycenter (security).

Their cache can take up to 1-2 GB.

Disposal of garbage through Safe Mode

Some files are not deleted in normal mode to be cleared:

1. Turn off the phone.
2. Press the power button + increase the volume before the MI logo appears.
3. In the recovery menu, select Wipe Cache Partition (not to be confused with Wipe Data!).
4. After restarting, check the free space in Settings → Storage.

Clear the cache of all applications >500MB|

Remove unused items APK from the Download folder|

Check the folder. MIUI/Extra (There's backups here)|

Clear the cache of Google Play Services (Settings) → Annexes → Google Play Services → Warehouse)-->

After cleaning, less 15% Memory - transfer files to SD-map. MIUI starts to slow down with less 3-5 GB of free space on the internal storage.

3. Optimization MIUI: disable unnecessary features

MIUI It's known for its "bunches," which look beautiful but eat resources:

Another hidden resource eater is location services, even if you're not using it. GPS, MIUI It can scan the networks continuously to "improve accuracy." Turn that off in Settings. → Location → Regime. → Device only (instead of "High accuracy").

💡

If after disabling animations, the interface seems too sharp, set the value 0.5x Instead of turning off - it will smooth the transitions, but will keep the speed increase.

On HyperOS models (e.g. Xiaomi 14), further disable “Game Turbo Mode” in Settings → Special facilities → This feature is designed for gamers, but in normal mode only consumes battery and slows down background tasks.

4. Setup of autoboot and background processes

MIUI It's the default that allows all applications to start when the system starts and hang in the background. It's one of the main causes of brakes:

Disconnecting the autoload

• 🛑 Go to Settings. → Annexes → Application management → Autoboot.
• 🔍 Turn off autoload for all apps except instant messengers (e.g. WhatsApp, Telegram).
• ⚠️ Do not touch system services with a gear icon – this can lead to failures.

Limitation of background activity

For applications that shouldn’t run in the background (such as games or rarely used utilities):

1. Open the Settings. → Annexes → Select the application → Battery.
2. Choose a limited (for games) or manual (for utilities).
3. Turn off Background Activity and Autostart.

For models with MIUI 13+ There is a hidden setting "Deep Optimization":

Settings → Battery → Battery settings → Deep Optimization (enable)

This feature aggressively closes the background processes, but can interfere with notifications in messengers.

5. Advanced methods: fine-tuning the system

If the basic methods don't work, it's time to dig deeper, and these are the ones that require precision, but they maximize productivity.

5.1. Change of I/O scheduler (I/O Scheduler)

On phones with Snapdragon, you can change the drive algorithm to speed up reading / writing:

1. Activate Developer Mode (see Section 1).
2. Go to Settings. → Additionally. → For developers → I/O scheduler.
3. Choose cfq (for balance) or noop (for maximum speed but risk of overheating).

For Mediatek processors (e.g. Redmi Note 11), this item may not be available – instead, use the background process restriction in the same developer menu (set the process maximum 2 value).

5.2. Disconnection MIUI Optimization (for experienced users only)

This method gives a performance increase of up to 30%, but turns off some chips MIUI (For example, dark theme on a schedule and navigation gestures, if you're willing to sacrifice convenience for speed:

Settings → Additional → For developers → MIUI Optimization (disable)

After the shutdown:

• 🔄 Reboot the phone.
• 🎯 Install an alternative launcher (like Nova Launcher) – a standard com.miui.home will brake.
• ⚠️ Some system applications (such as the Theme Store) will no longer be updated.

💡

Shutdown MIUI Optimization is most effective in older models (Redmi Note) 8/9, Mi 9), where performance is limited to iron. On new flagships (Xiaomi) 13/14) The increase will be minimal, but the battery life will increase.

5.3. Dalvik cache reset (for users with root rights)

If you have root, do it in TWRP through ADB:

su


cd /data/dalvik-cache




rm -r *




reboot

This will clear the cache of the Android virtual machine, which will speed up the launch of applications.Caution: after the reset, the first launch of each application will be longer than usual (the system recollects the cache).

6. Update of firmware and core

Outdated software is one of the main reasons for the brakes: Xiaomi regularly releases patches for optimization, but many users ignore them.

Verification of the current version

• 📋 Go to Settings. → The phone. → Updating the system.
• 🔄 Click on the three dots in the top right corner and select Update Package (if available).
• 📥 If the update weighs >1GB – Download over Wi-Fi to avoid crashes.

For models older than 2 years (such as the Redmi Note 9), the official updates may not be released.

1. Check the availability of custom firmware on Xiaomi.eu (European version) MIUI no-bloatware).
2. Or install the Pixel Experience (pure Android) — it will radically speed up older devices.

Update via Fastboot (if) OTA doesn't work)

If the phone does not see updates through the menu, but they are on the official website:

1. Download the firmware for your model (choose Fastboot, not Recovery).
2. Unpack. ZIP-file-back.
3. Connect your phone to your computer in Fastboot mode (press Power + Volume Down).
4. Run the script. flash_all.bat (Windows or flash_all.sh (Mac/Linux).

⚠️ Attention: Update via Fastboot erases all data, including photos and messages. pre-backup through Settings → Additionally. → Backup and reset or Mi Cloud (if synchronization is enabled).

6.3. Core optimization (for advanced)

On phones with an unlocked bootloader, you can install a custom core (for example, FrancoKernel or Perseus) for:

• 🔋 Improved battery management.
• ⚡ Optimizing the task planner.
• 🎮 Dispersal GPU (Carefully - the risk of overheating!).

Instructions for installation look for XDA Developers for their model.

7 Hardware methods: if nothing helps

If the software fails, the problem may be the hardware.

• 🔋 Worn-out battery: with capacity <50% The phone starts tratling the processor.
• 💾 Damaged Flash: If your phone is rebooted or crashed out of apps often, check the memory using ##6484## (memory test).
• 🌡️ Overheating: Clean the charging connector from dust and replace the thermopaste (relevant to the POCO F1, Redmi K20 Pro).

For models with removable battery (for example, Redmi) 4X) try:

1. Turn off the phone.
2. Remove the battery for 30 seconds.
3. Clear the contacts with alcohol.
4. Put it back in and turn it on.

If the phone is slowing down anyway, maybe it's time to think about replacing the heat conductive paste or memory module. UFS 2.1/2.2 (For example, Redmi Note 10 Pro) the memory controller often fails, resulting in lags when writing files.

8.Alternative solutions: if Xiaomi is completely outdated

If your Xiaomi is released before 2019 (like the Redmi Note 7, Mi 8), even deep optimization may not save you from the brakes.

For custom firmware, we recommend:

• 📱 Pixel Experience is the most stable pure Android.
• 🔧 LineageOS is flexible but requires manual installation GAPPS.
• 🎮 Havoc-OS – for gamers (optimized for performance).

Before installing, check the support for your model on the official LineageOS website.

💡

On older phones. 4 years (e.g. Redmi Note) 5) The scaling can increase productivity to 50-70%, reduce the battery life of the 10-15% due to lack of optimization MIUI.
