How to speed up Xiaomi Android phone: step-by-step instructions for all models

Is your Xiaomi smartphone slowing down, apps are slow to open and animations twitching? is a typical problem even for Redmi flagship models, POCO Or Mi after a year of active use, and the reason for the slowdown is not just because of the aging of iron, but because of the firmware. MIUI, And that's a problem that gets clogged with unnecessary processes over time, and fortunately, 90 percent of performance problems are solved by software -- without having to buy a new phone.

In this article, we will discuss 15 proven methods of acceleration, ranging from basic (cleaning the cache, disabling animations) and ending with advanced (setting the kernel through ADB, Background optimization: All methods tested on current versions MIUI 14/15 hyperos (2026 year) and suitable for Redmi Note models 10 Xiaomi 14 Ultra.Special emphasis is on solutions that don't require root rights -- most of them.

Before you start optimizing, identify a bottleneck on your device: if your phone is slow to open apps, but games are working normally — a problem in memory or background activity; if lags appear when you scroll through the interface, it's the graphics or overloaded launcher that's to blame. If the device overheats and starts to "brake" through 10 Minutes of play – processor optimization is needed/GPU.

1.Diagnostics: Why has Xiaomi become slow?

Before you fix something, you need to understand the root of the problem. Xiaomi smartphones slow down for 5 main reasons:

• 📱 Overloaded memory: less than 1 GB of free RAM or clogged storage (especially if free) < 10% of the total).
• 🔄 Background activity: MIUI aggressively caches applications, and some services (e.g. miui.analytics) run in the background even after closing.
• 🎨 Heavy interface: animations, live wallpaper and widgets MIUI Consume up to 15% of processor time.
• 🔋 Thermal throttling: overheating above 45°C processor automatically reduces the frequency (throttling).
• 🛠️ System garbage: application cache, residual files after updates, duplicates in the gallery.

To pinpoint the problem precisely:

1. Open the Settings. → The phone. → System status and check CPU/RAM load.
2. Launch Security → Optimization – the system will show what processes load the device.
3. Install. CPU Monitor (from Google Play) to monitor processor frequency in real time.

⚠️ Note: If you see in System State that RAM is loaded to 90%+ Even after rebooting, it is a sign of memory leakage in the MIUI. Solution - reset to factory settings or flashing.

For models with Snapdragon processors 8 Gen 2/3 (for example, Xiaomi 13T Pro, Redmi K60 Ultra is a problem with overheating due to aggressive energy saving policies, in which case it will help to disable Adaptive Battery in the battery settings.

2. Basic optimization: cleaning and setting MIUI

Start with simple steps that don't require deep knowledge. 15-30% Even on budget models like Redmi. 9A or POCO M4 Pro.

Cleaning up cache and garbage

• 🧹 System cache: Go to Settings → Warehouse → Clear the cache. Use Settings for deep cleaning. → Annexes → Application management → Clear all cache data.
• 🗑️ Residual files: In security → Select “Deep Clean” and remove unnecessary ones. APK, logs and temporary files.
• 📁 Duplicates in Gallery: Use the Gallery's built-in app → Albums. → Duplications or Files by Google to find repetitive photos.

Disabling unnecessary functions MIUI

Many "chips" of firmware MIUI/HyperOS They look good, but they slow down the system:

• 🌌 Live Wallpaper: Replace with static in Settings → Wallpaper.
• 📊 Desktop widgets: Remove everything but the most essentials (weather, hours).
• 🔍 Search by device: Disable in Settings → Additionally. → Search by device.
• 🎵 Sound effects: In Settings → Sound. → Sound effects turn off "Sound Improvement" and "Equalizer".

The critical point: If you have a model with AMOLED-screen (for example, Xiaomi 12 Pro or Redmi) K50 Pro, turn off Always On Display (Settings) → Screen. → This feature keeps the CPU core active all the time, which eats up to 10% of performance in the background.

Set up animations

Animations in MIUI They look beautiful, but they slow down the interface, to make it work faster:

1. Turn on Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Back to Settings → Additionally. → For developers and set: The scale of the animation window → Off or 0.5x Scale of transition animation → Off or 0.5x Animation time. → Quickly.

⚠️ Note: On some models (POCO F4 GT, Black Shark 5) Disabling animations can cause a black screen bug when games are curtailed. 1x.

3. Optimization of memory and background activity

The most common reason for brakes is a lack of RAM. MIUI It caches applications aggressively, but often does so inefficiently:

Manual setting of RAM

In the new versions MIUI (14+) And we have this feature called Extension Memory, which uses a portion of the internal storage as virtual RAM. 4-6 GB RAM (for example, Redmi Note) 11 or POCO M5):

1. Go to Settings → Additional → Expand memory.
2. Turn on the function and select 2 GB or 3 GB (maximum 8 GB, but this is redundant).
3. Reboot the phone.

For advanced users: use them. ADB-commands to globally disable background activity for all applications (except system):

adb shell cmd appops set <package_name> RUN_ANY_IN_BACKGROUND deny


adb shell cmd appops set <package_name> RUN_IN_BACKGROUND deny

Replace. <package_name> to the application ID (e.g. com.facebook.katana for Facebook).

Clear the cache in Settings → Storage

Enable memory extension (2-3 GB)

Disable Auto-Run for Unnecessary Applications

Set strict background restrictions for social networks

Reboot your phone after the changes-->

Resetting section cache /data

If the phone is slowing down after the update MIUI, Helps reset the cache section /data (Does not delete user data, but requires a reboot):

1. Turn off the phone.
2. Press the Power button + Volume up to enter Recovery.
3. Choose Wipe & Reset → Wipe Cache.
4. Confirm the action and restart.

⚠️ Note: On some models (Xiaomi) 11T Pro, Redmi K40) cache reset via Recovery can cause a reset of your fingerprint settings. save a backup in advance to Settings → Xiaomi account → Cloud.

4. Acceleration through Developer Settings

The hidden options in the Developer Menu allow you to fine-tune your performance, and these options are especially useful for gamers and flagship owners (Xiaomi 13 Ultra, Black Shark 5 Pro).

Optimization of the processor and GPU

In the Settings section → Additionally. → Find the developers:

• 🎮 Enforcement of use GPU: Turn on to speed up interface rendering (may reduce battery life).
• 🔄 Limiting background processes: Set a maximum of 2 processes to save RAM.
• 📈 Debugging by USB: Turn it on if you plan to use it. ADB deep-optimize.
• 🔋 Don't turn off the screen while charging: Useful for stress tests (but don't leave for long!).

For devices on Snapdragon 8+ Gen 1/2 (for example, Xiaomi 12S Ultra) is available to set up a performance profile:

1. Enable Forced Use 4x MSAA to improve graphics in games.
2. Install window animation/switch to 0.5x smoothly.
3. Activate. GPU-rendering for all applications (may cause artifacts in some games).

💡

If you change the developer settings and the phone gets overheated, you can return the Background Limitation to Standard, which will reduce the processor load.

Set-up thermal policy

MIUI By default, it aggressively restricts performance when it's heated:

1. In the developer menu, find Disable Temperature Control (or Thermal Engine on newer models).
2. For devices with Snapdragon 888/8 Gen 1 (for example, Xiaomi 11T Pro) Set Performance in Settings → Battery. → Performance mode.

Warning: Disabling thermal control could cause overheating above 50°C and automatic phone shutdown. Use only for short-term tasks (e.g. benchmarks).

5. Advanced methods: ADB modifications

If standard methods don't work, it's time to go deep optimization. ADB (Android Debug Bridge or modifications of system files, but give performance gains to the 40-50%.

Disabling unnecessary system applications

MIUI It contains dozens of pre-installed services that cannot be removed by standard methods. ADB You can turn them off without rooting:

1. Connect your phone to your PC and enable USB Debugging.
2. Open the command line and type: adb shell pm uninstall -k --user 0 com.miui.analytics pm uninstall -k --user 0 com.xiaomi.ab pm uninstall -k --user 0 com.miui.cloudservice pm uninstall -k --user 0 com.miui.cloudbackup pm uninstall -k --user 0 com.miui.bugreport
3. Reboot the phone.

List of safe to disable packets:

⚠️ Warning: Do not disable packages with the names com.android, com.qualcomm or com.miui.home – this can lead to bootloop (a looped reboot).

Change of I/O scheduler

For eMMC devices 5.1 or UFS 2.1/3.1 (For example, Redmi Note 11 Pro+, Xiaomi 12) Optimization of the storage:

1. Install Kernel Adiutor (requires root).
2. In the section I/O Select Scheduler for CFQ (for balance) or Duration (for speed).
3. Set Read-Ahead Boundary to 2048 KB.

For models with UFS 3.1 (Xiaomi 13 Pro, Redmi K60 Pro) better to use kyber or bfq.

Optimizing the kernel through Magisk

If you have root rights and Magisk installed, you can modify the kernel for better performance:

• 🔧 Install the module. FDE.AI Dynamically optimize processor frequencies.
• ⚡ Use PowerHalt to control the sleep states of the nuclei CPU.
• 🎛️ Set up Game Optimizer to force maximum performance in games.

Warning: Incorrect core settings can cause the battery to overheat or discharge quickly.Always back up through TWRP before experimentation.

6. Alternative firmware and launchers

If all methods failed, consider installing custom firmware or replacing the launcher, a radical but effective way to get the speed back.

Installation of custom firmware

For models with official support (POCO F1, Redmi Note 10 Pro, Xiaomi Mi A3) firmware:

• 📱 LineageOS: Clean Android without unnecessary services.
• ⚡ Pixel Experience: Firmware with Google Pixel features.
• 🔧 ArrowOS: Optimized for Performance.
• 🎮 Havoc-OS: For gamers with advanced settings GPU.

Requirements:

• Unlocked bootloader (instructions on the official Xiaomi website).
• Installed TWRP Or OrangeFox Recovery.
• Backup of data (firmware erases internal memory).

For models on MediaTek (e.g. Redmi Note) 12, POCO M5) The process of unlocking bootloader is more complicated - waiting is required 7-14 days after the application.

Replacement of the standard launcher

Launcher MIUI — One of the heaviest Android shells:

• 🚀 Nova Launcher: Lightweight, with gesture support.
• ⚡ Lawnchair: Minimalist, with the function "Adaptive icons".
• 🎨 Hyperion Launcher: Optimized for gaming phones.
• 📱 Rootless Launcher: For devices without root, but with advanced settings.

After installing an alternative launcher:

1. Turn it off. MIUI Optimization in Developer Settings (Disable Optimization) MIUI).
2. Remove the widgets MIUI (They may be in conflict with the new launcher).
3. Set up animations and gestures in the launcher settings.

💡

The scaling up of the productivity increases to 30-50%, They deprive you of official updates and can cause problems with the camera or modem (especially on models with MediaTek processors).

7. Optimization for games and heavy applications

If your Xiaomi is slowing down in games (Genshin Impact, Call of Duty Mobile, PUBG), Use these methods:

Setting up the Game Turbo

V MIUI There is a built-in game accelerator:

1. Open Settings → Special features → Game Turbo
2. Add the game to the list and activate it: 🎮 Performance mode (maximum frequency) CPU/GPU). 📵 Blocking notifications. 🔋 Turning off automatic brightness. 🔊 Sound amplification (for FPS-game).

For devices with Snapdragon 888/8 Gen 1 (Xiaomi 11T Pro, Black Shark 4) Game Turbo is available for setting GPU-rendering:

• Install OpenGL ES 3.2 or Vulkan (for supported games).
• Turn it on. 4x MSAA smoothing.
• Activate the Esport Mode (shows) FPS temperature).

Use of the GFX Tools

For fine-tuning graphics in games:

• Install. GFX Tool or Game Guardian (requires root for some features).
• For PUBG Mobile select: Resolution: Smooth + Extreme FPS Graphics style: HDR (if maintained) FPS: 90 (for screens with a frequency of 120 Hz)
• For Genshin Impact, install: Permission: 720p (stable FPS) Shadow Quality: Low Particle Effects: Average

⚠️ Attention: Use GFX Tools in online games (for example, PUBG Mobile or Free Fire can lead to a ban of an account for cheating.Tune only graphical settings without interfering with gameplay.

Phone cooling

Overheating is the main cause of lag in games.

• 🧊 External cooler: Use a smartphone cooler (e.g. Black Shark FunCooler Pro).
• 🔋 Game Charging Mode: In Game Turbo → Power settings select Fast Charging while playing (but this will speed up battery wear and tear).
• 🌡️ Temperature Limitation: In the developer settings, set to Turn off temperature control, but watch for manual heating.
• 📦 Removal of the case: Cases made of silicone or plastic worsen the heat sink on the 15-20%.

For emergency cooling:

1. Close all background applications.
2. Transfer the phone to air mode 2-3 minute.
3. Place the device on a metal surface (such as a laptop radiator).

8.If nothing helps: hardware solutions

If the software methods didn't work, the problem might be the hardware. Let's look at the hardware causes of the brakes and their solutions.

Battery wear and tear

A battery with a capacity below 80% of the nominal value leads to:

• 🔋 Automatic performance restriction (even if the charge is 100%).
• 📉 A sharp fall FPS post-game 10-15 minutes.
• ⚡ Frequent reboots under load.

Check the status of the battery:

1. Enter the dialer ##4636##.
2. Select Battery Information and see the Wear Level parameter.
3. Or install AccuBattery for detailed diagnosis.
