Your Xiaomi suddenly became slower to respond to touch, apps take a long time to open, and animations twitch? These are typical symptoms of "brakes" that every second user faces after the end of the year. 1-2 The reasons may lie in the memory filled, and system errors after the updates, but do not rush to the service center - in the service center. 80% In some cases, the problem can be solved independently. 10-30 minute.

In this article, we will discuss step-by-step instructions for diagnosing and eliminating lags on all Xiaomi, Redmi and other models. POCO (including budget and flagship devices, you will learn how to clear the cache without losing data, what settings to optimize in the future. MIUI, And then there's the list of apps that are most likely to cause brakes on Xiaomi in 2026.

1.Diagnostics: Why Xiaomi started to slow down?

Before you start "treatment", it is important to understand the root of the problem.

• 📱 Lags when scrolling through menus or social media feeds (especially on Facebook, TikTok).
• ⏳ Longer opening of applications (more 3-5 seconds).
• 🔄 Spontaneous reboots or relegations from games.
• 🔋 Fast battery discharge against the background of brakes (related to increased load on the processor).

Main reasons:

🔍 How quickly do you check? Go to Settings → The phone. → System state: If the memory section is less than 10% free and the processor has more than 50% downtime, the problem is precisely the system congestion.

2. Memory cleanup: remove garbage and cache

Let’s start with the simplest and most effective method, which is to free up memory. Even if you have Xiaomi with 128GB or 256GB, the system can slow down due to fragmented cache and temporary files.

🧹 Step 1: Cleaning the app cache

1. Open Settings → Applications → Application Management.
2. Select an app that slows down (like Instagram or YouTube).
3. Press Warehouse. → Clear the cache.
4. For complete cleaning, click Delete Data (⚠️ Attention: This will reset the application settings!).

🗑️ Step 2: Removal of Systemic Garbage

• 📁 Use the built-in Security app (shield icon) → Cleanup → Deep cleaning.
• 🔍 Check the Download folder – often unnecessary files accumulate there.
• 📊 B Settings → Click Free up space – the system will find large unnecessary files.

⚠️ Note: Do not delete files in folders MIUI, Android or manual system — this can cause system failure. For deep cleaning, use only built-in tools or proven applications like SD Maid.

3. MIUI Optimization: Hidden Settings for Acceleration

MIUI — It's not just a shell, it's a whole range of features that can both help and slow down a system. Many users are unaware of the hidden settings that make it faster for a smartphone.

⚡ Disabling animations (for advanced users)

Animations make the interface look more beautiful, but they slow it down.

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

🛠️ Limitation of background processes

MIUI By default, it allows applications to run in the background that eats up RAM:

1. Go to Settings → Applications → Application Management.
2. Select an application (for example, VKontakte) → Permits → Auto-start → Shut down.
3. For full control, use the settings → Battery and productivity → Battery management → Select charge saving mode (limits background activity).

4. Update and roll back firmware: when it helps

If the brakes appeared after the update MIUI, Xiaomi sometimes releases bug builds that slow down, in which case either a rollback to the old version or a forced upgrade to the latest patch version will help.

🔄 How to update MIUI manually:

1. Download the latest firmware for your model from the official Xiaomi website (choose Stable, not Developer!).

Recoiling is a more risky procedure, because it requires unlocking the bootloader, and if you're not sure, you should contact the service, but if you decide to do it yourself:

📌 When exactly you need to update:

• 🐞 If performance bugs are fixed in the latest firmware (read the reviews on the forums).
• 🔒 If the brakes are associated with security vulnerabilities (for example, after a virus attack).
• 🎯 If your model officially supports a new version of Android (for example, switching from Android 12 to 13).

• 🔄 Don’t restore all data from a backup at once – check the speed of a clean phone first.
• 📥 Install applications gradually, watching the performance.
• 🔒 Turn off auto-run for unnecessary applications (see Section 3).

6. Hardware problems: when the "iron" is to blame

If software methods don't work, the brakes can be caused by hardware malfunctions, most often the fault is:

• 🔋 Worn-out battery – when the discharge is below 20%, the processor automatically reduces performance.
• 💾 Damaged flash memory – if the phone overheats or falls frequently, memory chips could be damaged.
• 🔥 Overheating of the processor - due to dust in the connector or dried thermal paste.
• 📶 Faulty communication module – if the brakes appear when you turn on mobile Internet or Wi-Fi.

🔍 How to check for "iron»:

1. Battery: Install the AccuBattery app and check for wear. If the capacity has dropped below 70%, it's time to change the battery.
2. Memory: Run the test in AIDA64 (storage → Read/write test: speeds below 100MB/s indicate problems.
3. Processor: B CPU Throttling Test check if the processor frequency decreases when loaded.

🛠️ What you can do on your own:

• 🧹 Dust Cleansing: Gently blow the connectors with compressed air (do not use wet wipes!).
• 🔋 Battery replacement: For popular models (Redmi Note) 10, POCO X3) The batteries are sold on AliExpress for 500-1500 ₽.
• 🔥 Thermopaste: If the phone overheats, the service can replace the thermopaste (cost) ~1000 ₽).

⚠️ Warning: If after falling or getting moisture, the phone starts to brake, do not turn it on - this can lead to a short circuit.

7.Apps that are slowing Xiaomi in 2026

🚫 Which apps to remove first:

• 🧹 All the cleaners and boosters (they only mask the problem).
• 🎮 Games you haven’t played for more than a month (e.g., games you haven’t played, PUBG Genshin Impact is up to 10GB!).
• 📱 Duplicate applications (for example, two browsers or two messengers).

🔄 Alternatives for heavy applications:

• 📷 Instagram Lite instead of Instagram (weighs 2MB instead of 100MB).
• 🎵 Instead of Spotify, YouTube Music (better optimized for Spotify) MIUI).
• 📺 Instead of Kodi, it has built-in Mi Video (supports most formats).
