How to speed up Xiaomi phone: from cleaning garbage to flashing

Why Xiaomi is starting to slow down and how to fix it

Xiaomi, Redmi and Poco are known for their price-performance ratio, but even top-end models gradually start to slow down. MIUI, According to our tests, even the flagship Xiaomi 14 Pro after a year of operation can lose up to 30% of performance due to clogged memory and incorrect settings.

In this article, a practical guide to speeding up a phone without losing functionality, we will examine both basic methods (cleaning the cache, turning off animations) and advanced ones (change the firmware, optimize the kernel). 10 Xiaomi 13T and working on current versions MIUI 14/15 hyperos.

Important: If your phone has started to brake after upgrading to HyperOS, the problem may lie in unoptimized drivers for your model - in this case, only a rollback or custom firmware installation will help (about this in section 6).

1. Diagnostics: What exactly is slowing down your Xiaomi

Before you start optimizing, you need to identify bottlenecks. 80% of the time, the brakes are caused by:

• 📱 Overloaded RAM (background applications, games, browsers)
• 🗑️ Clogged cache (system garbage, remnants of remote applications)
• 🔋 Energy-saving settings (MIUI aggressively restricting productivity)
• 🤖 Services. MIUI (Advertising, analytics, cloud synchronization)

For accurate diagnosis:

1. Open the Settings. → The phone. → Version. MIUI and tap 5 times on the line "Kerole" - will turn on the developer mode.
2. Back to Settings → Additionally. → For developers and activate: 📊 Process statistics (will show the load on the CPU) 📈 Loading schedule CPU (visualization of processor use) 📉 Do not turn off the screen (for real-time monitoring)

If you see in the monitoring that com.miui.analytics or com.xiaomi.market are constantly loading the processor, you can safely disable them (for this in section 3).

2. Cleaning the system: remove garbage and cache

The first step to speed up is to free up space and clean up temporary files. On Xiaomi phones, the cache accumulates in 3 places:

1. Application cache – temporary files of games and software (can take up to a maximum of three years) 5-10 GB)
2. System cache - update files and logs MIUI
3. Dalvik cache – optimized files for fast downloading applications

To turn off:

1. Activate the Developer Mode (as in Section 1).
2. Install ADB on your computer and connect your phone.
3. Follow the commands (one by one): adb shell pm disable-user --user 0 com.miui.analytics adb shell pm disable-user --user 0 com.xiaomi.midrop adb shell pm disable-user --user 0 com.miui.cloudservice adb shell pm disable-user --user 0 com.miui.player

⚠️ Warning: Disabling com.android.updater will block security updates.Do this only if you are ready to install firmware manually.

For those who do not want to use ADB, there is an alternative:

1. Install the App Inspector app (available on Google Play).
2. Find unnecessary system applications by batch names from the list above.
3. Click Disable (Do not "Delete"!).

After disabling unnecessary services, check:

• 🔋 Battery life (should be increased by the 10-15%)
• 📱 App Opening Speed (especially noticeable on Facebook, Instagram)
• 🔄 Smoothness of animations when swiping between screens

💡

If theme or wallpaper stops working after the services are turned off, return com.android.themes with the adb shell pm enable com.android.themes command.

4. Performance setting: Hidden MIUI options

V MIUI And HyperOS has hidden settings that allow you to manually control CPU and memory performance, which are undocumented, but work on most models. Xiaomi/Redmi/Poco.

To start, activate the developer mode (as in Section 1), then:

Optimization CPU

1. Go to Settings → Additional → For developers.
2. Find the parameters: 🔧 Limitation of background processes → Set a maximum of 2 processes ⚡ Optimization MIUI → turn off 📊 Turn on 4x MSAA → Turn off (improves graphics, but slows down)

Set up animations

Reducing animation time visually speeds up the interface:

1. Find it for developers: 🎞️ Window animation scale → 0.5x or off. 🔄 Transition animation scale → 0.5x ⏱️ The length of the animator → 0.5x

⚠️ Attention: On models with AMOLED-screens (Xiaomi 12 Pro, Redmi) K50 Pro) turning off animations may cause flickering at low brightness. 0.5x.

For maximum effect combine these settings with limited background activity:

1. Go to Settings → Battery → Battery Mode.
2. Choose Performance (not Balanced!).
3. B Settings → Annexes → Permits → Autorun disable autorun for all applications except instant messengers.

💡

The combination of disabled animations, limitations of background processes and the “Performance” mode gives an increase in interface smoothness up to 40% (tested on Xiaomi) 11T Pro).

5. Alternative firmware: when standard MIUI brake

If all previous methods did not help, the problem may be in the firmware itself. MIUI (Especially on budget models like Redmi. 9A POCO M3) Often poorly optimized, and updates bring more bugs than fixes.

Options:

For custom firmware installation:

⚠️ Note: On models with a locked loader (Xiaomi) 12S Ultra, Redmi Note 12 Pro+) Before the firmware, you need to unlock the bootloader through the official Mi Unlock tool, which erases all data and requires binding to the Mi Account!

The following is a step-by-step instruction for Pixel Experience:

1. Unlock the loader (if necessary).
2. Install. TWRP For your model (download only from the official website).
3. Download the firmware from the official website (select the version for your model code, for example, alioth for Poco). F3).
4. Boot in. TWRP (Power + Vol+) And do it: Wipe. → Advanced Wipe → Dalvik, Cache, System, Data Install → Choose. ZIP reboot firmware → System

6.Iron Optimization: Battery, Cooling and Memory

Even with perfect software settings, the physical condition of the phone affects performance.

🔋 Battery and energy saving

Old or bloated batteries make the processor work in a low mode (throttling).

1. Enter the dialer: ##4636###
2. Select Battery Information.
3. Look at the level of wear and tear (health). <80% — battery-change.

For an interim solution:

• 🔌 Turn off optimized charging (Settings) → Battery → Battery settings)
• 🔋 Set a charge limit of up to 80% (prolong the life of the battery)
• ⚡ Use the original power supply (slow charges heat less)

❄️ Overheating and throttling

Xiaomi is known for overheating problems, especially models with Snapdragon 888/8 Gen 1 (Xiaomi 11T Pro, Black Shark 4). Higher temperatures 45°C processor automatically reduces frequency, which leads to brakes.

How to lower the temperature:

• 🧊 Use cooling stands for games
• 🔄 Limit it. FPS in games up to 60 (in graphics settings)
• 📱 Remove the cover during heavy use
• 🔧 Turn it off. 5G (If not, the modem is very warm.

To check throttling:

1. Install Throttling Test CPU from Play Market.
2. Run the test. 15-20 minute.
3. If the graph shows a frequency drop below 50%, you have a strong throttling.

💾 Memory and storage

On eMMC phones (all budget models until 2022) filled storage (>90%) severely inhibits the system:

• 📱 RAM: Always have a minimum of free 1-1.5 GB
• 💾 ROM: free at least 10-15% (for example 128 GB — 12-15 GB)

How to free up memory:

• 🗑️ Move the photo/video to Google Photos (High Quality compression does not take place)
• 🎮 Use microSD for games (but not all models support Adoptable Storage)
• 📱 Turn off the map cache in Google Maps (Settings) → Warehouse)

7 Radical methods: Iron discharge and replacement

If the phone is slowing down even after all the optimizations, there are two radical options:

🔄 Hard Reset (Hard Reset)

Restores the phone to factory settings, deletes all data, helps in cases where:

• 🐌 System Lags after Update
• 🔄 Cycle reboot (bootloop)
• 📱 Unreasonably high battery consumption

How to reset:

1. Save all data (photos, contacts, SMS).
2. Go to Settings → About the phone → Reset settings.
3. Select Delete all data.
4. Confirm the action.

⚠️ Note: On models with encryption (all phones with Android 10)+) You may need to enter your old password after reset, and if you forget it, the phone becomes a brick"!

🛠️ Replacement of components

For older models (Redmi Note 5, Mi) A2) Sometimes it's cheaper to replace iron than to buy a new phone:

For battery replacement:

1. Buy the original battery (check the model number on Kimovil's website).
2. Use plastic shoulder blades for a careful opening.
3. Turn off the battery plume first, connect last.
4. After replacement, calibrate the controller (discharge to 0%, charge to 100%).

⚠️ Note: On models with frameless screen (Xiaomi Mi Mix 3, Redmi) K30 Pro) self-replacement of the battery can damage the display.

8 Prevention: How to Prevent Brakes in the Future

To Xiaomi phone does not slow down over time, follow the simple rules:

• 🔄 Update the firmware once in a while. 2-3 month (but not immediately after the release – wait for reviews)
• 📱 Do not install SEOs like Clean Master or DU Speed Booster – They only make things worse
• 🔋 Use quality chargers (original or certified Anker, Baseus)
• 📲 Limit background activity of social networks (in the settings of each application)
• 🛡️ Don’t put antiviruses – they are useless in Android and load the system

For games:

• 🎮 Install lightweight versions (PUBG Mobile Lite, Call of Duty Mobile Lite)
• 🔧 In the graphics settings, choose Balanced Mode, not HDR/Ultra
• ❄️ Use Game Turbo (Settings) → Special facilities → Game Turbo)

For the long life of the phone:

• 🔋 Keep battery power in range 20-80%
• 🌡️ Avoid overheating (do not leave in the sun, do not play when charging)
• 📱 Reboot your phone once a month (even if it’s always on")
