Xiaomi phone brakes and lags: the complete guide to speeding up Android

Xiaomi smartphone started to slow down when opening apps, hangings appear even in the settings menu, and animations twitch like a slideshow? MIUI after 1-2 The reasons can be in software failures and hardware limitations. In this article, we will examine all possible ways to diagnose and eliminate lags, from basic to radical, including hidden Android settings that the manufacturer does not advertise.

It's important to understand that brakes don't always mean that a phone is "outdated," and that cache, fragmented memory, or conflicting backgrounds are often to blame. 10 pro POCO X3 Pro with Snapdragon processor 732G They should theoretically fly, but in practice, users complain of hanging because of unoptimized software. MIUI 14/15 (Android 13/14) And we just picked out the ones that actually increase productivity.

1.Diagnostics: why Xiaomi is slowing down on Android

Before you start "treatment", you need to identify the root of the problem, and the brakes can manifest themselves in different ways:

• 🐢 Slow app opening (especially Google Play, YouTube, Telegram)
• 🔄 Hanging when scrolling the tape in social networks or switching between tabs
• 🎮 Lags in games (PUBG Mobile, Genshin Impact, previously stable
• 🔋 A sharp drop FPS post-refresh MIUI Android
• 📱 Overheating of the body and spontaneous resets

The main culprits are:

• 🗑️ Overflowing memory: less than 10% of the available space on the internal drive
• 🧹 Cache of system and user applications (especially) MIUI Launcher)
• 👻 Background processes: autoloading unnecessary services (Mi Push, Analytics)
• 🦠 Viruses or malware in third-party APK
• 🔄 Conflicts after the update (for example, switching from Android 12 to 13)
• 🔋 Degraded battery (capacity below 70% of nominal value)

To determine the cause accurately, perform a basic check:

1. Open Settings → About Phone → MIUI version and check the relevance of the firmware.
2. Run Settings. → Memory and see how much space is left.
3. Install the app AIDA64 (Free version) and check the temperature of the processor under load.

⚠️ Attention: If the phone starts to brake only when connected to charging, the problem may be in the power supply or cable.Use of non-original accessories with higher power 30W often leads to processor trottling.

2.Cache and garbage cleanup: Quick methods

In 80 percent of cases, the brakes are removed by the simple cleaning of temporary files. On Xiaomi, the cache accumulates in three places:

1. Application cache (including system)
2. Dalwick Cache (optimized files for fast download)
3. Cash. MIUI (launcher and design topics)

The easiest way is to use the built-in Security utility:

1. Open the Security app (the shield icon).
2. Go to the Cleanup section. → Deep cleaning.
3. Check all the points and click Clear.
4. Go back to the main menu and select Acceleration. → Optimize.

For advanced users, there is a more radical method – manually clearing Dalvik cache through Recovery:

Turn off the phone.|Squeeze the power. + Loudness up|Choose Wipe & Reset → Wipe Dalvik Cache|Confirm the action.|Reset the device-->

After this procedure, the first turn on will take up to 5 minutes, which is normal. MIUI, When the system creates duplicate optimized files.

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

3. MIUI Optimization: Hidden Performance Settings

MIUI It contains a lot of hidden features that you can activate to make things faster, and most of them are hidden in the developer settings to enable them:

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version (you will be notified "You became a developer").
3. Go back to the main settings menu and open a new section for developers.

Now activate these parameters:

• 🚀 Accelerate. GPU-rendering (Debugging) → Accelerate processing GPU)
• 🖥️ Forced. GPU-rendering (Debugging) → Forced use GPU)
• ⚡ Restriction of background processes (Annexes) → Limit of background processes → Maximum 2 of the process)
• 🔄 Disabling animation (Debugging) → Scale of window/transition animation = 0.5x)

Pay special attention to the item Do not save actions (Debugging) → Do not save actions. Its activation will remove all background processes when the application is closed, which will increase the number of times the application is closed. 15-20% performance, but some notifications may be delayed.

Another effective trick is to change the firmware region. ROM often works more slowly than EEA (Europe, or India, because of the differences in optimization, to change the region:

1. Download the firmware for your model from en.miui.com (select the Stable version).
2. Rename the file to update.zip and place it in the root of the memory.
3. Run Settings. → The phone. → Updating the system → Select a firmware file.

⚠️ Warning: Change region will reset all data! Before the procedure, make a backup through Settings → Additionally. → Backup and reset.

4. Background and autoboot management

One of the main reasons for the brakes on Xiaomi is the aggressive autoload of system and third-party applications. Even after closing, many programs continue to work in the background, consuming the same amount of power. CPU For example, Mi Video, Mi Browser and GetApps often run on their own.

To turn off autoboot:

1. Open Settings → Applications → Application Management.
2. Select an unneeded app (such as Mi Pay).
3. Slip AutoRun and turn off the slider.
4. Go back and select permissions. → Other permits → Display over other windows - turn off.

Use the AutoStart Manager app to disable the mass (rights required) ADB). It can also block auto-runs of system services, for example:

• 📱 com.miui.analytics (collection of statistics)
• 🔔 com.xiaomi.mipush (push notifications)
• 🌐 com.android.browser (built-in browser)

Commands to shut down through ADB (run on PC):

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


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

Once you've done the commands, reset the phone. 300-500 MB of RAM, but some features (such as update notifications) may not work properly.

💡

If notifications from banking apps stop coming after the autoboot is turned off, return permissions for com.google.android.gms and com.android.vending – they are responsible for the operation of Google Play Services.

5. Resetting: When nothing helps

If all the previous methods fail, you'll have to reset hard, which is a last resort, but it's guaranteed to bring the phone back to factory status.

• 📱 Make a backup of the data through Settings → Google → Backup.
• 🔐 Take a picture or login/passwords from your accounts.
• 📁 Transfer photos and videos to PC or cloud.

Resetting instructions:

1. Open Settings → Additional → Backup and Reset.
2. Select Resetting → Delete all data.
3. Enter. PIN-code (if installed) and confirm the action.
4. Wait until it is completed (it will take 5-10 minutes).

After discharge:

• 🚫 Do not restore data from backup MIUI — It'll bring back the old problems.
• 🔄 Install only the necessary applications (avoid junk utilities like cleaners). RAM).
• ⚡ Turn off automatic app updates on Google Play.

⚠️ Note: On Xiaomi models with a blocked bootloader (such as the Redmi Note 12), a reset via Fastboot can lead to hard-brick (completely inoperable.

Hardware problems: when the "iron" is to blame

If the software didn't work, the brakes could be caused by hardware malfunctions.

• 🔋 Degraded battery: With capacity below 70%, the phone begins to limit performance.
• 🔥 Overheating of the processor: due to dried thermal paste or dust-clogged ventilation grille.
• 💾 Damaged flash memory: bad sectors on the drive cause freezes when reading / writing.
• 📶 Faulty communication module: problems with the antenna or modem can slow down the network.

Check the status of the battery through the application AccuBattery (Health section). 2000 mAh (for models with battery) 4000-5000 The cost of the original battery for Xiaomi — from 1500 before 3000 ruble.

To diagnose flash memory, use the command in ADB:

adb shell dumpsys diskstats

If you have bad block or read errors in the output, the drive is damaged, and then the replacement of the motherboard will help.

The temperature of the processor can be tracked in AIDA64 (Sensors. Normal values under load:

• Snapdragon 7xx/8xx: before 75°C
• Mediatek Helio: up to 80°C
• Snapdragon 4xx: 65°C

If the temperature exceeds these values, dust cleaning or replacement of the thermal paste is required.

💡

On models POCO F3 redmi K40 A common problem is that the heat pad is detached between the processor and the radiator, and that causes overheating and trottling at 60.°C.

7. Alternative firmware: whether to switch to caste

If standard methods don’t help, some users are considering installing custom firmware (like LineageOS, Pixel Experience or ArrowOS).

• 🚀 No “junk” from Xiaomi (no unnecessary services Mi Push, Analytics).
• 🔄 More frequent security updates.
• 🎨 Ability to fine-tune the interface.

There are, however, downsides:

• 🔋 Possible battery problems (some customized for Xiaomi).
• 📱 Loss of warranty (if the phone is under warranty).
• 🔊 Non-functioning modules (e.g, NFC or IR-blaster on some firmware).

If you are going to experiment, follow this instruction:

1. Unlock the bootloader through the official Xiaomi tool (requires a Mi Account and wait 7 days).
2. Install TWRP Recovery for your model (see instructions on XDA Developers).
3. Download firmware (e.g. Pixel Experience for Redmi Note 10 Pro) and GApps files (Google services).
4. Using TWRP, run Wipe → Advanced Wipe (mark Dalvik, Cache, System, Data).
5. Install firmware and GApps, then restart.

⚠️ Note: On models with a Mediatek processor (e.g. Redmi) 9A) Unlocking the bootloader can lead to loss IMEI. Before the procedure, save it through the command adb shell su -c 'dd if=/dev/nvram of=/sdcard/nvram.bin'.

8 Prevention: How to Prevent Brakes in the Future

To prevent Xiaomi phone from slowing down again, follow these rules:

• 🧹 Once a month, clean the cache through Settings. → Warehouse → Clear the cache.
• 🔄 Don't update. MIUI In the first 2 weeks after the release – wait for feedback on stability.
• 📱 Remove unused apps (especially heavy ones like Facebook or TikTok).
• 🔋 Use original chargers (power not higher than specified in the characteristics).
• 🛡️ Turn off automatic download of media in messengers (WhatsApp, Telegram).

For models with a small amount of RAM (2-3 HB recommended:

• 🎮 Use Lite versions of apps (e.g. Facebook Lite, Messenger Lite).
• 📺 Disable interface animation (Developer settings) → Scale of animation = Off.).
• 🔄 Enable the option Settings → Special facilities → Simplified regime.

If you are actively playing mobile games, install Game Turbo (the built-in Xiaomi utility) and set up a performance profile:

1. Open Settings → Special features → Game Turbo
2. Add the game to the list and select Performance mode.
3. Activate the Memory Cleanup option when you start the game.

💡

In the models with AMOLED-Include a dark theme and reduce autobrightness time with a screen (for example, Xiaomi 12) – this will reduce the load on the processor and increase the time of operation.

By following these tips, you will prolong the life of your Xiaomi 2-3 The main thing is to avoid filling the memory "to the end" and regularly follow the updates.
