Xiaomi is laying and slowing down: what to do to speed up the smartphone

Your Xiaomi is slowing down, apps are late, and the interface twitches when scrolling? This is a common problem faced by owners of Redmi smartphones, POCO And Mi, both budget and flagship models, can be caused by overloaded memory, outdated firmware, background processes, or even hardware malfunctions.

In this article, we will discuss all possible ways to eliminate lags, from simple (cleaning the cache) to radical (flashing). 12T Pro with Snapdragon 8+ Gen 1 can be affected by errors in the MIUI. We will also tell you how to diagnose the problem and avoid repeated failures.

1.Diagnostics: Why Xiaomi started to lay

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

• 📱 The interface twitches when scrolling through the menu or launching apps;
• ⏳ Long loading of programs (more than 3-5 seconds);
• 🔄 Spontaneous reboots or flights to Fastboot;
• 🔋 Overheating and fast battery discharge with minimal load.

Main reasons:

How to quickly determine the cause? Launch the settings → The phone. → Version. MIUI And you can click on the version a few times, and it'll open the hardware test menu (not all models), and you can check the performance of the processor, memory and screen.

2. Cleaning up memory and cache: the first step to speeding up

In 80 percent of cases, the brakes are caused by a clogged memory or an overloaded cache, and let's start with the simplest thing, we free up space and reset temporary files.

Clearing the application cache

Cash speeds up the software, but over time it accumulates and starts to slow down the system, to clean it up.

1. Go to Settings → Applications → Application Management.
2. Select an app (such as Facebook or Instagram) → Warehouse.
3. Click Clear Cache (do not delete data unless you want to lose logins!).

For mass cleaning, use the built-in Optimization utility (the broom icon in the application menu).

Release of internal memory

MIUI It requires at least 10 to 15 percent of the space available on the internal drive to work smoothly, and if there's less memory, the system starts to lag:

• 📁 Go to Settings. → Warehouse;
• 🗑️ Delete unnecessary files (downloads, duplicate photos, old ones) APK);
• 🔄 Move heavy applications to SD-card (if supported).

Critical error: if after cleaning the memory lags remained, and in the section "Storage" displays "System files" size 20+ GB is a sign of failure MIUI. Solution: Resetting settings or flashing.

3. Disable animation and visual effects

MIUI It's known for its heavy animations, which look beautiful but slow down on weak smartphones, and you can turn it off through the developer mode:

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Back to Settings → Additionally. → For developers.
3. Find the items: The scale of window animation → No animation; scale of transition animation → No animation; duration of animation → Off..

Also, turn off unnecessary visual effects:

• 🌈 Settings → Screen. → Lock screen style → pick a static wallpaper;
• 🔄 Settings → Additionally. → Special opportunities → Remove animations.

💡

If after disabling animation interface became "twitched", turn back the scale of animation on the 0.5x — It is a trade-off between smoothness and productivity.

4. Optimization of background processes and autoboot

Many applications continue to run in the background, consuming RAM and battery power, to limit them:

Limitation of background activity

Go to Settings. → Annexes → Application management, select a program (e.g., TikTok) and:

• 🚫 Shut down Autostart;
• 🔄 Set a limit on background activity;
• 📵 Disable access to Locations and Notifications (if not required).

4.2 Disconnecting unnecessary services MIUI

Some system processes can be safely disabled:

• 📡 Mi Cloud Sync (unless you use the cloud);
• 🎵 Music FX Mi Video (if you use other players);
• 📊 Analytics and MSA (Xiaomi statistics collection).

Use the settings to turn off → Annexes → Show it all. → Systemic.

⚠️ Warning: Do not disable processes called com.android. or miui. – This can lead to the collapse of the system.

5. Update firmware and reset settings

If the lags appeared after the update MIUI — The firmware may contain errors:

1. Settings → About the phone → Updating the system;
2. If you have an update, install it (preferably via Wi-Fi).

What if the phone starts to lag more after the update?

• 🔄 Reverse to the previous version via Fastboot (instruction below);
• 🧹 Make a reset (but save the data!);
• 🛠️ Fly your phone through the Mi Flash Tool (radical method).

If you decide to reset the settings:

1. Save data to Mi Cloud or PC;
2. Go to Settings → About the phone → Reset settings;
3. Select Erase All Data (not Reset!).

6.Verification for viruses and malware

Malware often disguises itself as system processes and loads the processor.

• 📈 Unexplained traffic consumption;
• 🔋 Quick battery discharge;
• 📱 The emergence of unknown applications.

How to check and remove viruses:

1. Install Malwarebytes or Dr.Web Light from Google Play
2. Run a deep scan;
3. Remove the threats and reboot the phone.

If the antivirus has not found anything, but suspicions remain:

• 🔍 Check the list of installed applications in Settings → Annexes;
• 🚫 Remove suspicious programs (especially those with Chinese names);
• 🛡️ Disable the installation from unknown sources (Settings) → Confidentiality).

⚠️ Note: Some Google Play "optimizers" (such as Clean Master) may themselves be the source of lag. Use only proven utilities.

7. Hardware problems: when to carry in the service

If all the software methods didn't work, it could be hardware.

How to check the status of the battery?

1. Enter the dialer code: ##4636##;
2. Go to the Battery Information;
3. Check the parameter Wear level (if any) Up to 20%.

Use the application to diagnose memory AIDA64 (storage → Reading/write: If the speed is below 100MB/s, the memory is worn out.

💡

If the phone starts to lag after falling or getting moisture, do not try to repair yourself. Oxidation of contacts or microcracks on the board can lead to complete failure.

8 Radical methods: flashing and replacement of software

If none of these methods have helped, then there are extreme measures:

Installation of custom firmware

Official. MIUI It can be slowing down because of the abundance of unnecessary services:

• 📱 Xiaomi.eu - "clean" MIUI softwareless;
• 🤖 LineageOS or Pixel Experience – firmware based on Android;
• ⚡ DerpFest – optimized firmware for weak smartphones.

Installation instructions:

1. Unlock Bootloader (via Mi Unlock Tool)
2. Install. TWRP Recovery;
3. Select the selected firmware via Wipe → Install.

⚠️ Warning: Unlock bootloader will reset all data! also some features (e.g., bootloader, IR-blaster NFC) They may stop working on custom firmware.

8.2.Return to the old version MIUI

If the lags started after the update, go back to the previous stable version:

• 🔗 Download the firmware from Xiaomifirmwareupdater.com;
• 📱 Go to Fastboot and go through the Mi Flash Tool;
• 🔄 After the firmware, reset the settings.

💡

Before you run your firmware, check the version compatibility with your model! For example, the firmware for the Redmi Note 10 Pro (sweet) won’t work for the Redmi Note 10 (mojito).
