How to speed up Xiaomi smartphone: proven methods for all models

Your Xiaomi has started to slow down, apps are opening long, and animations are twitching? This does not always mean that it is time to buy a new smartphone. 80% of the time the slowdown is due to software factors: overloaded memory, background activity of applications or unoptimized MIUI settings. Even flagship models like Xiaomi 14 Ultra or Black Shark 6 Pro after 1-2 years of operation can lose their former frolicity.

In this article, we will discuss 10 proven ways to speed up Xiaomi, from basic (cleaning the cache, turning off animations) to advanced (setting the kernel, disabling MIUI-bloat). All methods are tested on current versions of MIUI 14/15 and HyperOS, work on the budget Redmi Note 12 and top-end Poco F6 Pro. Importantly, some tweaks require unlocking the bootloader or root rights - we will note them separately.

1.Diagnostics: Why your Xiaomi is slowing down

Before you optimize, you need to understand the source of the lags. Xiaomi has built-in diagnostic tools:

• 🔍 Performance Monitor: Go to Settings → The phone. → System monitor. This shows CPU load, RAM and temperature. If CPU is loaded at 80%+ In simple – look for a virus or a heavy app.
• 📊 Battery Analysis: C Settings → Battery. → Battery use: see which apps are using up energy in the background, often the culprits are messengers (Telegram, WhatsApp) or games.
• 🚨 Error Logs: If the smartphone spontaneously reboots or crashes into bootloop, check logs through Settings → Additionally. → Error report.

Typical causes of brakes:

⚠️ Note: If you see a high-load com.miui.analytics process in the System Monitor, this is Xiaomi's full-time statistics collector. ADB (section).

System Cleanup: Cache, Garbage and Unnecessary Files

The first step is to free up space and delete temporary files, and even on smartphones with 256GB of storage, cache can cause lags.

• 🧹 Cleaning the application cache: go to Settings → Annexes → App management, select each and click Clear cache. Use Settings for bulk cleaning → Memory. → Cleanup.
• 🗑️ Removal of unnecessary APK: post-update MIUI You can still have old firmware files. → Memory. → Files. → System files.
• 📁 Storage optimization: transfer photos/video to the cloud (Google Photos, Mi Cloud) or to a memory card. Use Files by Google to analyze the location.

For deep cleaning, use ADB commands:

adb shell pm trim-caches -d 1000000000


adb shell cmd package bg-dexopt-job

The first command clears the cache of all applications, the second optimizes DEX-Files (accelerates the start of programs).

⚠️ Note: Do not use cleaners like Clean Master or CCleaner, which delete important system files and can break MIUI. Enough built-in tools.

3. MIUI Optimization: Hidden Settings for Speed

MIUI has a lot of hidden features that you can turn on to speed things up, some of which require activation through ADB or a developer.

• ⚡ Disabling animation: go to Settings → The phone. → Version. MIUI (Tap 7 times for Developer Mode. Then in Settings → Additionally. → For developers, set: The scale of the window animation → Disable Transition Animation Scale → Disable the duration of the animator → 0.5x
• 🎯 Enable Performance Mode: In the same developer settings, activate Do Not Turn Off the Screen While Charging and Limit Background Processes (select Maximum 2 of the Process).
• 🔄 Resetting the launcher settings: if MIUI Launcher brakes, reset its settings through Settings → Annexes → Application management → Launcher → Warehouse → Resetting settings.

For models with AMOLED-screen (Xiaomi) 13T, Poco F5) turn on DC Dimming in Settings → Display. → This will reduce the burden and reduce the burden on GPU.

4. Background and auto-start management

One of the main bottlenecks of MIUI is the background activity of applications, and even after closing, many programs continue to work, consuming RAM and battery power.

• 🛑 Disabling Autostart: Go to Settings → Annexes → Application management → Auto-run and disable unnecessary apps (especially games and social media).
• 🔕 Background restriction through MIUI Optimization: in Settings → Battery. → Select Economy or Balanced (but not Performance – it overclocks the CPU but reduces the running time).
• 📵 Block notifications: go to Settings → Notifications and disable notifications from unnecessary apps. Each pop-up loads the processor.

For advanced users: you can disable system services that are not used through ADB:

adb shell pm disable-user --user 0 com.miui.analytics


adb shell pm disable-user --user 0 com.xiaomi.ab

This will disable Xiaomi’s analytics and advertising services.

💡

If after disabling autorun no notifications from messengers, add them to the exceptions in Settings → Battery → Exceptions

5. Updating firmware and kernel: when it helps

Sometimes the brakes are caused by bugs in the firmware or an outdated kernel. Xiaomi regularly releases updates, but not all users install them.

• 🔄 Check for updates: go to Settings → The phone. → Update MIUI. If a new version is available, install it, especially for HyperOS models (e.g. Xiaomi 14 or Redmi). K70).
• 🐧 Kernel Update: If you use a custom core (like FrancoKernel or Kirisakura), check the relevance through TWRP or Kernel Adiutor.
• 📦 Switching to custom firmware: for older models (Redmi Note 9 Pro, Poco) X3) current-age MIUI You can't get it. Consider LineageOS or Pixel Experience.

Before updating:

1. Make a backup through Settings → Additional → Backup.
2. Charge your phone at least 50%.
3. Connect to Wi-Fi (updates weigh 1-3 GB).

⚠️ Note: If after the update the smartphone stopped turning on (bootloop), try resetting through Recovery (press Power). + If it doesn't work, you'll need to flash it through the Mi Flash Tool.

6 Hardware methods: when software does not help

If all of the above fails, the problem may be in the iron:

• 🔋 Battery wear: With a capacity below 80%, the smartphone begins to trott (lower performance). Check the battery health via AccuBattery or ##4636## (test menu).
• 💾 Memory problems: on budget models (Redmi) 10A, Poco M4) It uses a slow eMMC memory. 90%+ Read/write speed drops in 2-3 The solution is to vacate or replace the module with UFS (if maintained).
• 🌡️ Overheating: if the CPU temperature exceeds 60°C, trottling goes off. Clean the dust charger connector, replace the heatpaste (this requires disassembly skills).

For a performance test, use AnTuTu Benchmark or Geekbench. Compare the results with the benchmarks for your model:

If the scores are below the benchmark by 30%+, a diagnosis is required in the service center.

💡

Replacing thermopaste with Xiaomi gives a performance boost of up to 15% by reducing trottling, especially for gamers (Black Shark, Poco F).

7. Alternative firmware and custom cores

For experienced users willing to sacrifice the warranty, there are radical acceleration methods:

• 📱 Custom firmware: Pixel Experience is pure Android without Xiaomi blobate. LineageOS is stable firmware with long-term support. HyperOS (official) - optimized version MIUI new-model.
• ⚙️ Castom cores: FrancoKernel - balanced core for everyday use, Kirisakura - for maximum performance (risk of overheating), Perseus - optimized for gaming.
• 🔓 Root rights: with them you can disable all unnecessary services, disperse the CPU/GPU (Kernel Adiutor, but this will void the warranty.

Instructions for installing TWRP and custom firmware:

1. Unlock the bootloader through Mi Unlock Tool (requires a Xiaomi account binding).
2. Install TWRP via fastboot flash recovery twrp.img.
3. Download the firmware (for example, from XDA Developers) and transfer it to your phone.
4. Boot in. TWRP (Power + Vol Up and stitch ZIP-file.

⚠️ Warning: Inept firmware can turn your phone into a brick. Before the procedure, check the firmware compatibility with your model (codename of the smartphone can be found through adb shell getprop ro.product.device).

Extreme measures: discharge and replacement of components

If nothing has worked, radical methods remain:

• 🔄 Hard Reset: Returns the phone to factory settings. → Additionally. → Reset settings or Recovery (Wipe) Data/Factory Attention: all data, including photos and messages, will be deleted!
• 🔧 Battery replacement: If capacity falls below 70%, the battery not only goes down quickly, but causes trottling.The original Xiaomi batteries cost 1,500-3,000 ₽.
• 💾 Replacement of memory: on some models (Redmi Note) 10 Pro, Poco X3 Pro) you can change the eMMC to UFS. This will speed up the loading of applications on 40-50%.

Cost of repairs in service centers:

Before resetting or repairing, be sure to remove SIM-map SD-map - they can be damaged by unstable nutrition.

💡

If the smartphone is warranty, do not disassemble it yourself! Contact the official Xiaomi service - repair warranty will cost less.
