Why Xiaomi is Lagging: 12 Proven Ways to Speed Up Your Phone

Your Xiaomi is slow to work, apps are late to open and animations are twitching? This is a common problem faced by owners of smartphones brand — from budget Redmi Note to flagship Xiaomi 13. the causes of brakes can be hidden in both software failures and hardware limitations. In this article, we will examine all possible causes and give step-by-step instructions for their elimination — from simple actions to radical measures.

It's important to understand that if a phone starts to slow down after 1-2 years of active use, it's often associated with wear and tear on flash memory (especially on models with eMMC instead of UFS). But in 80% of cases, the problem can be solved software-free without going to the service center.

1.Reset is the first step to a solution

It sounds trivial, but a forced reboot eliminates up to 30 percent of time lags, because MIUI (or HyperOS on new models) uses cache and background processes, and over time they accumulate and conflict.

How to properly reboot:

• 🔄 Soft reboot: Press the power button, select Reboot (if the menu does not open – see next item).
• ⚡ Hard reboot: Press the power button + volume up 10-15 It's good if the screen is frozen.
• ⏳ Recovery mode: If the phone doesn't respond, try the power combination + volume up until the Mi logo appears.

After the reboot, check the performance. If the lags are left, move on to the next step. Xiaomi on Snapdragon processors (for example, Redmi Note 12 Pro+) are more likely to suffer from overheating, and models on MediaTek (Poco X5) are more likely to suffer from unoptimized software.

2. Cleaning up cache and garbage

MIUI is known for its love of data caching, and over time, temporary files take up gigabytes of memory and slow down, and can be cleaned manually or with built-in tools.

Method 1: Through settings

1. Open the Settings → Memory.
2. Click on "Clean" (or "Optimize").
3. Select "Deep Clean" to delete unnecessary files.

Method 2: For individual applications

• 📱 Go to Settings. → Annexes → Application management.
• 🧹 Select a problem app (such as Facebook or TikTok) → "Warehouse" → "Clear the cache".
• 🚫 Do not clear data – this will delete accounts and settings!

💡

If the app gets worse after cleaning the cache (for example, YouTube is loading videos longer), give it 5-10 minutes to re-caching the data.

To automate the process, use the built-in Security application:

1. Open Security. → "Optimization".
2. Click "Clean up garbage" and "Speed up."
3. Enable the option "Autoclean" in the application settings.

3. Disable animation and visual effects

MIUI and HyperOS are overloaded with animations that look beautiful but slow down on weak smartphones, and turning off the extra effects can speed up work by 15-20%.

How to turn off animation:

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Back to Settings → Additionally. → For developers.
3. Find the items: Window animation scale → Disable the animation scale of the transition → Disable the animator duration → Disable

Additional settings for acceleration:

• 🎨 Turn off Dark Theme (if not used): Settings → Display. → Dark subject matter.
• 🖼️ Install static wallpaper instead of living.
• 🔍 Turn off Screen Search (swipe down on the home screen).

In the models with AMOLED-On the other hand, a dark theme can save charge and reduce heat. check the performance difference in both modes.

4. Optimization of background processes

MIUI aggressively controls the background, but sometimes it works against the user, and applications can be slowed down by the system's constant sedation.

Autostart setup:

1. Go to Settings → Applications → Application Management → Autorun.
2. Enable auto-run for frequently used applications (messengers, social networks).
3. Turn off autoplay for unnecessary services (e.g. Mi Video, Mi Music).

Turning off battery optimization:

• 🔋 Go to Settings. → Battery → Optimizing the battery.
• 🔍 Find a problem app (such as Telegram) → Choose "No restrictions".
• ⚠️ Don’t turn off optimization for all apps – it will cut battery life!

On models with a Snapdragon 8 Gen 2 processor (for example, Xiaomi 13T Pro) background processes are less critical, but on budget Redmi with Snapdragon 4xx, each extra process significantly slows down the system.

5. Update of firmware and core

The slowdown is often due to outdated firmware or bugs in the current version of MIUI/HyperOS. The manufacturer regularly releases patches that fix performance issues.

How to update software:

1. Go to Settings → About the phone → System update.
2. Click "Check Updates."
3. If a new version is available, download and install (be sure to connect to Wi-Fi!).

If automatic updates do not help:

• 🌐 Download the firmware manually from the official Xiaomi website (choose the version for your model!).
• 📁 Move the file to the root of the phone’s memory (folder) downloaded_rom).
• 🔄 Go to Settings. → The phone. → Updating the system → Threefold → Select a firmware file.

After the update, reset the cache (Wipe Cache) through Recovery:

1. Turn off the phone.
2. Press the power + volume up until the logo appears.
3. Select Wipe & Reset → Wipe Cache (control – volume buttons, choice – power button).

💡

Updating via Fastboot (from PC) is the last resort if the phone doesn't turn on. requires an unlocked bootloader and can result in data loss.

6.Reset to factory settings

If all the previous methods failed, it's a complete reset, and it's a radical solution, but it returns the phone to factory speed.

How to reset:

1. Create a backup copy: 📱 Through Settings. → Google → Backup (saves contacts, photos, some settings). 💾 Or manually copy important files to your PC/cloud.

• 🔄 Through the menu: Settings → The phone. → Resetting settings → Erase all data.
• 🛠️ Recovery: Choose Wipe & Reset → Wipe All Data.

After discharge:

• ❌ Do not restore data from a backup right away – check the performance of a clean system first.
• ⚡ Install only the necessary applications (over-programs are the main cause of brakes).
• 🔒 Turn off the automatic installation of recommended apps on Google Play.

⚠️ Note: On models with eMMC memory (e.g. Redmi) 9A) Frequent resets accelerate memory wear. Use this method no more than 1 time in 6 months.

7.Verification for viruses and malware

Viruses and adware are a common cause of not only brakes, but also overheating, fast battery discharge, and even if you didn't install suspicious apps, malicious code could get in through:

• 📎 Investments in WhatsApp/Telegram.
• 🌐 Sites with pirated content.
• 🎮 Mods for games (for example, Free Fire or PUBG Mobile).

How to check your phone:

1. Install antivirus (recommended Malwarebytes or Dr.Web Light).
2. Run a full scan.
3. Remove any threats you find.

Additional signs of infection:

If the antivirus does not find threats, but suspicions remain, check the list of installed applications in Settings → Apps.

8 Hardware problems: when you need to use the service

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

• 🔥 The phone overheats even after reset (possibly the heat paste has dried or the processor is damaged).
• 💾 Applications are slowed down when reading/write (wear and tear of eMMC flash memory).
• 🔋 Battery swollen (presses on motherboard causing failures).
• 📶 Bad network signal (communication module malfunction).

What you can do on your own:

• 🛠️ Replace the heat paste (requires disassembly of the phone).
• 🔋 Check the battery: if it is swelling, replace it immediately!
• 🔌 Test the charger: non-original RAMs can cause voltage drawdowns.

To diagnose memory, use the AIDA64 app:

1. Install AIDA64 from Google Play.
2. Go to the "Storage" section" → "Read/write test".
3. Compare the results with the reference for your model (for example, the Redmi Note 11 should show at least 200 MB / s per read).

⚠️ Warning: If the phone falls into a bootloop (cyclic reboot) or doesn't turn on after firmware, don't try to repair yourself. EMMC-chips – a soldering station and an experienced master are required.
