Xiaomi Optimization: 15 Proven Ways to Speed Up Smartphone and Smart Tech

Xiaomi devices are known for their price-quality ratio, but even flagship models eventually start to slow down. MIUI This article will help you get your Redmi back, POCO or Mi initial speed without contacting the service center.

We will consider both basic methods (cleaning the cache, disabling unnecessary applications) and advanced techniques (setting the processor core, optimizing the background). MIUI). All instructions are relevant to the devices on MIUI 14/15 HyperOS, including models 2020-2026 We will pay special attention to the problems specific to Xiaomi equipment: aggressive optimization of background processes and specific firmware bugs.

Important: Before you start optimizing, check the available space on the device. If there is less than 10% of internal memory left, first free up space - this can solve up to 40% of performance problems without additional manipulation.

1. Diagnostics of the current state of the device

Before you start optimizing, you need to understand what exactly is slowing down your Xiaomi.

• 📊 MIUI Battery & Performance – Built-in monitor shows boot CPU/GPU, Temperature and energy consumption. Pathway: Settings → Battery and productivity → Monitor
• 🔍 DevCheck (Play Market) – displays detailed information about the processor, RAM and storage, especially useful for checking the real frequency of cores.
• 📈 AccuBattery – analyzes battery wear that can indirectly affect performance when activating energy saving modes.

Please note the following indicators:

• Downloading CPU above 70% in downtime
• Processor temperature above 45°C without load
• Free RAM less than 1 GB
• Battery life has been reduced by 30% or more

If at least two of these metrics are out of the norm, your device needs comprehensive optimization, otherwise basic measures will suffice.

⚠️ Note: On devices with MediaTek processors (Helio series, Dimensity), the temperature in the idle can reach 50°C is normal for a given architecture, but if the temperature is above 55,°C without load, this indicates problems with heatpast or cooling.

2. Cleaning the system of digital garbage

The first and most obvious step is to delete unnecessary files. MIUI There are built-in tools for this, but they often miss important points.

Start with manual cleaning:

1. Remove the app cache: Settings → Annexes → Application management → [Select the application] → Warehouse → Clear the cache
2. Clean up downloads: The Download folder often contains gigabytes of unnecessary files
3. Remove duplicate photos/video with Google Files or Files by Xiaomi
4. Clear history in instant messengers (especially Telegram and WhatsApp – they can take up to 5 GB)

For deep cleaning, use a combination of:

adb shell pm trim-caches -1

This command clears the cache of all user applications, and it requires developer rights and connection to run it. ADB.

Remove the cache of all applications

Check the download folder

Clear the history of messengers

Remove unused APKs

Check the folder. Android/obb-->

⚠️ Note: Do not use “optimizers” like Clean Master or CCleaner – they often delete important system files and can disrupt your work. MIUI. Use only the built-in Security App from Xiaomi.

3. Optimization MIUI: hidden settings

Shell MIUI It contains a lot of hidden options that you can configure to improve performance, some of which are available through the developer menu, some through the engineering menu.

Activate the Developer Mode:

1. Go to Settings. → The phone.
2. Press 7 times on the version MIUI
3. Return to the main settings – there will be a paragraph for developers

Key settings for optimization:

• 🔧 Windows animation: Set the value 0.5x Or turn it off completely (Developer Settings) → The scale of window animation)
• 🔄 Background processes: Limit to 2-3 Process settings (Developer settings) → Limit of background processes)
• 📶 Debugging by USB: Include for use. ADB-team
• 🔋 Don't turn off the screen: Useful for testing, but don't leave it on permanently

For advanced users, an engineering menu (code ##4636##) is available where you can:

• View detailed information about the battery
• Testing sensors.
• Set up network parameters

Critical for Snapdragon-based devices: Turn off the Disable option in the developer settings HW overlays – its activation can lead to graphic artifacts and overheating.

4.Manage autoload and background processes

One of the main problems MIUI — aggressive control of background processes, on the one hand, it saves battery, on the other, leads to constant reboots of applications.

To set up the autoload:

1. Go to Settings → Applications → Application Management
2. Select the desired application → Auto-start
3. Turn off auto-run for unnecessary apps (especially for games and social media)

To control background activity:

• 🔄 B Settings → Battery and productivity → Battery management select "No Limits" mode for critical applications (messengers, navigators)
• 🚫 Avoid background activity for applications that you rarely use
• 🔋 Turn on the Adaptive Battery – it analyzes your habits and optimizes background processes

💡

For applications that are constantly rebooted (such as Spotify or Yandex.Navigator), add them to "Memory Cleanup Lock" in the battery settings, which will prevent them from being closed by the system if there is a shortage of RAM.

5. Performance optimization for gaming

Xiaomi devices are often positioned as gaming, but by default many settings limit their potential.

Activate Game Turbo mode:

1. Go to Settings. → Special facilities → Game Turbo
2. Add the right games to the list
3. Set up the parameters: 🎮 Performance: Select "High Performance" 📶 Network: Enable "Traffic Priority" 🔋 Battery: Turn off restrictions

For advanced users available ADB-run-off:

adb shell settings put global force_high_performance true


adb shell settings put global force_4x_msaa true

These teams are pushing maximum productivity. GPU And they're going to include anti-aliasing. Be careful, because it increases heat and battery consumption.

For devices with Snapdragon processors 8 Gen 2/3 Available to adjust the performance of the cores:

• 🔧 Use Kernel Auditor app to manually adjust frequencies
• 📊 Optimal settings for performance/heat balance: Small cores: 1.8-2.0 GHz Medium cores: 2.4-2.6 GHz Large cores: 3.0-3.2 GHz (maximum)

💡

For liquid-cooled devices (e.g. Xiaomi) 13 pro POCO F5 Pro) can safely increase the frequencies to 10-15% On models with passive cooling acceleration is not recommended.

6. Update of firmware and core

Regular updates are key to stable performance, and Xiaomi releases two types of updates:

• 📲 Stable versions – tested builds with minimal bugs
• 🧪 BBETA/Developer Versions contain new features but may be unstable

Check out the current version of the firmware:

1. Settings → The phone. → Version. MIUI
2. Compare it with the latest versions on the official website MIUI Downloads

Refreshment methods:

For devices with unlocked bootloader, custom firmware is available:

• 🔄 LineageOS – pure Android without unnecessary services
• ⚡ Pixel Experience – firmware with Google Pixel functionality
• 📱 Xiaomi.EU – Optimized version MIUI without Chinese services

⚠️ Attention: Installing custom firmware on devices with a locked bootloader (most official devices) will result in a "brick" (inoperability.

7. Battery and energy optimization

Incorrect energy saving settings can both improve and impair productivity. MIUI multiple modes available:

• 🔋 Balance is the best choice for most users
• ⚡ Performance – maximum power, fast discharge
• 🌿 Savings of charge – limits background processes
• 🔄 Adaptive – automatically adjusts to your habits

To extend the life of the battery:

1. Limit the charge to 80% through Settings → Battery → Battery settings → Charging to 80%
2. Turn off the "Always Active Display" (Settings) → Screen. → Always active display)
3. Set up a sleep schedule for Wi-Fi/mobile

Check the battery health:

• 📊 In the engineering menu (#4636##) select "Battery Information"
• 🔋 The health setting should show good.
• 📉 If the capacity has fallen below 80% of the original, consider replacing it.

💡

For battery calibration (if the device suddenly turns off when the battery is 20-30% charge) completely discharge the phone, then charge to 100% Repeat the procedure without interruption. 2-3 once.

8 Additional optimization methods

If the basic techniques didn’t help, consider these advanced techniques:

• 🔄 Resetting to factory settings is a radical method, deletes all data, but returns a "clean" system. → The phone. → Resetting settings
• 📱 Shutdown MIUI Optimization (requires root): adb shell settings put global miui_optimization_disabled 1 Removes restrictions MIUI on background processes, but may increase battery consumption.
• 🔧 Replacement of thermopaste is relevant for devices older than 2 years that overheat. POCO F1 Redmi Note 8 Pro can give performance up to 20%.
• 📶 Shutdown 5G (If not used, saves battery life. → SIM-maps and mobile networks → Preferred type of network → LTE

For devices with HyperOS (new models 2026) available additional optimizations:

• 🔄 Include “Deep Optimization” in Settings → The phone. → Optimization of the system
• 📊 Use the built-in Performance Monitor to analyze system load
• 🔋 Activate Smart Resource Allocation for Automatic Memory Management

⚠️ Note: On HyperOS devices, disabling system optimizations (as in older versions) MIUI) This system is more integrated with the Android core.
