How to increase the performance of Xiaomi phone: from simple ways to deep optimization

Your Xiaomi is slowing down, apps are opening for a long time, and animation is twitching? The problem is not always the "aging" of iron - in 80% of cases, the system settings, overloaded cache or background processes are to blame. POCO The new model can work smoothly with the right optimization, and the flagships Mi 13 or Xiaomi 14 will reveal the full potential. MIUI.

In this article, we have proven methods of acceleration, from basic (memory cleaning) to advanced (disabling system services through the use of the system). ADB). We will explain why even new Xiaomi smartphones slow down after a month of use, and what to do about it. MIUI 14/15 It is adapted to different models – from Redmi Note. 10 Xiaomi 13 Ultra.

Importantly, if you've had all the lags left, the problem could be hardware (weary flash memory, overheating of the processor), and then only the service center will help. But in 90% of cases, software methods are enough, read on.

1.Diagnostics: Why Xiaomi started to slow down?

Before optimizing, you need to understand the root of the problem. Brakes on Xiaomi are divided into 3 categories:

• 🔋 Software: overloaded memory, background processes, errors MIUI. Treated with settings and cleaning.
• 📱 Hardware: battery wear (low charge braking), chipset overheating, damaged flash memory. Requires repair.
• 🔄 System: outdated firmware, conflicting updates, viruses, solved by flashing or resetting.

How do you determine your case?

🔹 Quick Test: Open Settings → The phone. → Version. MIUI And press "Core" 5 times if you have a menu. CIT (Xiaomi internal test, select Performance Test – the system will show the bottlenecks.

⚠️ Attention: if in CIT You see errors in the section. eMMC/UFS (memory, it's a sign of chip wear. Optimization won't help, we need a replacement.

2. Cleaning the system: remove garbage and cache

The first thing you need to do is clear space and clear the temporary files. 1-2 GB of free space can return smoothness of work.

Integrated tools MIUI

Xiaomi offers its own cleaning utilities:

1. Open Security → Cleaning (icon with broomstick).
2. Click Deep Clean and select all items (cache, residual files, duplicates).
3. Go to the AutoStart tab and turn off autoboot for unnecessary apps (especially instant messengers and social networks).

🔹 Hidden function: in Cleaning → Settings enable Cleanup when blocked – the system will automatically remove garbage when the screen is turned off.

Manual cleaning of the cache

Some apps (like Facebook or TikTok) can take gigabytes of cache to manually clean it.

1. Go to Settings → Applications → Application Management.
2. Select an app (e.g. Chrome) → Storage → Clear the cache.
3. System applications (e.g. com.miui.gallery) may need to Clear Data, but this will reset settings.

⚠️ Warning: Do not clear the cache for Android System WebView and Google Play Services – this can break the browser and app store.

Remove unnecessary APK from the Download folder|Clear the cache in Settings→Warehouse|Turn off autostart for 10+ applications|Remove duplicate photos through the gallery→Smart cleaning-->

Clearing Dalvik cache (for advanced)

If the phone is slowing down after the update MIUI, It's going to help you clean up Dalvik-cache, which is a temporary file on the Android virtual machine:

1. Turn off the phone.
2. Press Volume Up + Power to enter Recovery.
3. Select Wipe & Reset → Wipe Cache (not to be confused with Wipe Data!).
4. Reset the device.

⚠️ This method will reset app optimization, so once the phone is restarted, it may run slower. 5-10 minutes (until the system reassembles the cache).

Once a week.|Once a month|Only when it starts to brake.|Never clean.-->

3. Optimization of RAM (RAM)

Lack of RAM is the main reason for lags on budget Redmi (4/6 GB of RAM, even if you have a flagship with 12 GB RAM, Incorrect settings can "eat" resources.

Background processes offline

MIUI aggressively holds apps in memory even when they're not needed to limit it:

1. Go to Settings. → About the phone and press 7 times on the version MIUI, to enable Developer Mode.
2. Back to Settings → Additionally. → For developers.
3. Find the Process Limit and select the Maximum 2 process in the background (for weak phones) or the Standard Limit (for flagships).

🔹 Extreme method: In the same menu, turn on Do Not Save Actions – this will kill all background processes when you exit the application, but can break notifications.

3.2. virtual memory setting (RAM Expansion)

Starting with MIUI 12.5, Xiaomi has added RAM expansion to internal memory, which is not a magic wand, but can help on devices with internal memory. 4-6 GB RAM:

1. Open the Settings. → Additionally. → Expansion of memory.
2. Enable the feature and select the size (recommended 2GB for 6GB) RAM or 3GB for 8GB RAM).
3. Reboot the phone.

⚠️ Note: Virtual memory is slower than physical memory and speeds up switching between applications, but does not increase the speed of the switch. FPS On flagships (Xiaomi 13 Pro, POCO F5) minimalism.

Forced closure of “heavy” annexes

Some programs (such as Genshin Impact or CapCut) can take up to 1.5 GB. RAM Even in the background, to force them to close:

1. Open Settings → Applications → Application Management.
2. Choose a "glutty" app → Forced stopping.
3. For games, it is also useful to turn off Auto Start and Background Activity.

💡

If the game is lagging, close all background apps through the “Clear” button in the multitasking menu (swipe up and hold) before launching.

4. Customization of animation and interface MIUI

MIUI It's known for its smooth animations, but they can slow down on weak phones, and turning off or speeding up transitions will give you a boost in performance.

4.1 Accelerating animation through developer modes

Hidden settings allow you to reduce the duration of animations or disable them completely:

1. Activate Developer Mode (see Section 3.1).
2. Go to the Developers and find:
3. Window animation scale → set up 0.5x or Otklaz.
4. Transition animation scale → 0.5x or Otklaz.
5. The length of the animator → 0.5x or Otklaz.

🔹 Effect: the interface will react instantly but lose smoothness. - Redmi 9A or POCO M3 gives +15-20% speed.

Switch to "Light Interface" mode

MIUI Has a hidden mode Lite Mode, simplifying the interface for weak devices:

1. Open the Settings → Screen.
2. Click on Display Mode → Choose the Light.
3. Reboot the phone.

This regime:

• 🎨 Simplifies animations and transitions.
• 📉 Reduces consumption RAM on 10-15%.
• ⚡ Increases the Autonomous Work Time.

⚠️ Note: Some functions are disabled in Lite Mode MIUI, Super Wallpapers and the effects of paralax.

Disabling unnecessary visual effects

MIUI It's overloaded with decorative elements that slow down weak phones:

• 🌌 Settings → Screen. → Super wallpaper (eat up to 300MB) RAM).
• 🔄 Settings → Additionally. → Special effects → Turn off Transition animation and Opening effects.
• 📊 Settings → Battery → Performance mode → Select Balanced (High Performance Mode Warms the CPU).

💡

Disabling animations gives the greatest speed increase on phones with Snapdragon processors 6xx and Helio Gxx (Redmi 9, POCO M4, etc.).

5. Optimization of firmware and updates

Outdated or “curved” firmware is a common cause of brakes. Xiaomi regularly releases updates, but not all of them are optimized.

Verification of relevance MIUI

Make sure you have the latest version of the firmware:

1. Open Settings → About the phone → System update.
2. Click on the three dots in the upper right corner → Update the package.
3. If the update is available, download it over Wi-Fi and install it.

🔹 Important: if after the update the phone began to brake more, perhaps a new version MIUI It is not optimized for your model, and then rollback will help (see section 5.3).

5.2 Resetting the update cache

Sometimes the system forgets downloaded updates or they are downloaded with errors.

1. Go to Settings → Applications → Application Management.
2. Find System Update (or com.android.updater).
3. Click Warehouse → Clear the cache and Clear the data.
4. Restart your phone and check the updates again.

5.3. rollback to stable firmware (for experienced)

If after the update there are lags, you can go back to the previous version MIUI. This is risky – if the wrong actions the phone can turn into a brick".

🔹 Step-by-step instruction:

1. Download the desired firmware version from the official Xiaomi website (choose Stable, not Developer).
2. Rename the file to update.zip and place it in the root of the phone’s memory.
3. Press Volume Up + Power to enter Recovery.
4. Select Install update.zip and confirm the installation.

⚠️ Attention: rolling back on old firmware can break some features (such as a camera or fingerprint). → Additionally. → Backup.

Advanced methods: ADB and hidden settings

If standard methods don't work, it's time to move to "heavy artillery," which requires knowledge and caution, but produces maximum effect.

6.1. Shutdown MIUI Optimization (acceleration to the 20-30%)

MIUI hidden-function MIUI Optimization, which slows down some processes, and it's a noticeable increase in speed, but it's stripping away some of the signature chips, like navigation gestures).

🔹 Instructions:

1. Connect your phone to your PC and turn on Debugging USB (Settings → For developers).
2. Download ADB Tools and unpack it into a folder.
3. Open the command line in this folder and type:

adb shell


settings put global miui_optimization_disabled 1

Reboot your phone. Use:

settings put global miui_optimization_disabled 0

This method is particularly effective on phones with Snapdragon processors. 7xx/8xx (POCO F3, Xiaomi 11T, Redmi K40), where MIUI Artificially restricts productivity.

6.2 Restriction of Google Background Services

Google Play Services can consume up to 500MB RAM. They can be limited:

1. Go to Settings → Applications → Application Management.
2. Find Google Play Services → Battery → Select a Limited Background Mode.
3. Repeat for Google App and Google Play Store.

⚠️ After that, they may stop working:

• 📍 Accurate location in Google Maps.
• 🔔 Push notifications from some applications.
• 🔄 Automatic synchronization of Google account.

Setting up the task scheduler (for Snapdragon)

On phones with Qualcomm Snapdragon processors, you can optimize your task scheduler for better performance:

1. Connect to the phone through ADB (see section 6.1).
2. Enter a command to check the current scheduler:

adb shell cat /sys/block/sda/queue/scheduler

1. If cfq or bfq is displayed, replace it with noop or deadline (for the first time). SSD-accumulator UFS 2.1/3.0):

adb shell echo noop > /sys/block/sda/queue/scheduler

🔹 Effect: Reduced lags when reading/write files (especially noticeable in games and when copying large files).

⚠️ Warning: Incorrect scheduler settings can cause data loss or overheating of the drive.Do not use this method on phones with eMMC memory (Redmi 8, POCO M2).

7 Hardware Methods: When Software Optimization Does Not Help

If all of the above methods fail, the problem may be in the "iron" here's what to check first:

Checking the status of the battery

Worn-out battery (capacity) < 70%) can cause CPU trottling, which is an artificial performance reduction to save energy:

1. Install the AccuBattery app from Google Play.
2. Charge your phone to 100% and check the battery health score.
3. If the value is below 70%, the battery needs to be replaced.

🔹 Symptoms:

• 🔋 The phone brakes sharply when the charge is below 30%.
• 🔥 Heated even in plain space.
• ⚡ Fast discharge (e.g. Redmi Note 10 holds charge for less than 4 hours).

Dust cleaning and thermal paste replacement

Dust in the case and dried thermopaste can cause overheating, which causes the processor to lower frequencies.

1. Install CPU Monitor or AIDA64.
2. Run a heavy application (such as Genshin Impact).
3. If the processor temperature exceeds 75°C, and the frequency falls below the maximum - you need to clean up.

🔹 What do you do:

• 🛠️ To take to the service for cleaning and replacing thermopaste (cost: 1000-2000 ₽).
• 🌬️ Use a cooling case or fan stand (e.g. Black Shark FunCooler).

7.3. Memory diagnostics (eMMC/UFS)

A worn flash memory can cause lags when reading/write data. ADB:

adb shell


cat /sys/block/sda/sda/device/life_time

If the value exceeds 0xA0 (160 in decimal system), memory is worn out and needs replacement.

🔹 Signs of memory wear:

• 🐢 Slow opening of applications (even after cleaning the cache).
• 💾 Errors when writing files (for example, photos are not saved).
• 🔄 Phone "hang" on the logo MI post-boot.

⚠️ Attention: replacement eMMC/UFS-memory costs 3000-6000 ₽ It requires soldering work. 3 It's cheaper to buy a new one.

8. Alternative firmware: should you switch to caste?

If optimization MIUI It didn't help, some users are switching to custom firmware (like LineageOS, Pixel Experience or ArrowOS:

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

🔹 Cons:

• ❌ Loss of guarantee.
• ❌ Some functions do not work, for example, IR Blaster or Always-on Display).
• ❌ Risk of "bricking" if installed incorrectly.

🔹 Firmware recommendations:

🔹 Important: Before the firmware make a backup through TWRP Check the compatibility of your model with XDA Developers.

💡

The scaling up of the productivity of 15-30%, But they take away official Xiaomi support, and only use them if you're prepared for the risks.
