Why Xiaomi is Glitting: System Failures, Lags and How to Fix Them

Introduction: When Xiaomi Techniques Start to “Capitalize”

Xiaomi devices - from smartphones Redmi and POCO before Mi TVs TV — They're famous for their value for money, but even they're not immune to failure, and users often find themselves in a situation where the gadget suddenly starts to "glut": slows down the interface, spontaneously reboots, doesn't respond to touch, or gives out app errors. The reasons for this behavior can be hidden as in software bugs. MIUI, and in hardware problems.

It's important to understand that the term "glut" combines dozens of different symptoms, from harmless lags to critical failures requiring repair. In this article, we systematize the most common problems, analyze their root causes and offer proven solutions. We will focus on recent models (2022-2026), but most of the tips are relevant for older devices.

Before you panic and bring your phone to the service center, go through our checklist, and 80 percent of the time, you can fix the problem yourself, from cleaning the cache to flashing it, and if it's hardware, we can tell you how to diagnose the malfunction and estimate the cost of repairs.

1. Software bugs: firmware is to blame MIUI

The most common cause of failures - errors in the corporate shell MIUI. Xiaomi releases updates regularly, but new versions don't always pass enough testing: Typical symptoms of software glitches:

• 📱 Freezes when opening apps (especially Google Play Services or Mi Account)
• 🔄 Self-involved reboots after update
• 🖥️ Artifacts on the screen (shimmering, stripes, distorted colors)
• 🔊 Problems with sound (distortion, loss of sound in speakers)

The first thing to do is to check the version. MIUI in settings (Settings) → The phone. → Version. MIUI). If your version is older than MIUI 14 (for smartphones) or MIUI TV 3.0 (for TVs), chances are that the bugs have already been fixed in more recent builds. → Updating the system.

If the problem occurs after the update, try:

1. Reset the settings of the application causing the failure (Settings) → Annexes → Application management → [attachment] → Warehouse → Clear the cache).
2. Reverse the update (if available) or wait for the next patch.
3. Install custom restoration (for example, TWRP) and run a stable version MIUI manually.

⚠️ Note: Do not install firmware marked Beta or Developer on the main device. These builds contain experimental functions and often cause a critical slowdown of the system.

2.Overheating: When Xiaomi 'gaps' from load

Overheating is one of the main causes of arbitrary shutdowns and lags. There are often two extremes in Xiaomi devices:

• 🔥 Budget models (e.g. Redmi) 9A or POCO M3) They are warmed due to low cooling and processors with high temperature TDP.
• ❄️ Flagships (e.g. Xiaomi 13 Ultra) can overheat when tasks are intense (games, video rendering) due to aggressive overclocking of the chipset.

How to diagnose overheating:

1. Install the app AIDA64 or CPU Monitor and check the processor temperature in simple and under load.
2. Normal values: up to 40-45°C in plain, up to 65-75°C under load if the temperature exceeds 80°C, this is critical overheating.
3. Check if the battery is swelling (visually or by the characteristic “slapping” sound when pressing the back cover).

Decisions:

• 🧊 Clean the device from dust (especially important for Mi). TV and Mi Notebook laptops).
• 🔋 Turn off fast charging if the phone is warming up while charging.
• 🎮 For gamers: activate Game Turbo mode in settings or set a limit FPS play.
• 🔄 Reset to factory settings if overheating started after upgrade.

💡

If your Redmi or POCO warms up even in simple, try turning off background activity for applications in battery settings (Settings) → Battery → Optimizing the battery).

3.Memory Lack: Why Xiaomi is Braking Like a Brick

Even Xiaomi’s flagship models can turn into lag machines if RAM is packed with background processes, especially on devices with 4-6 GB of RAM, where the system aggressively kills applications, but consumes up to 50% of memory in the background.

How to check memory usage:

1. Open the settings → About the phone → Memory.
2. See the RAM Usage chart – if less than 1GB is free, this is a critical level.
3. Click Clear Memory (but this is a temporary fix).

Long-term solutions:

• 🗑️ Turn off autoloading of unnecessary applications (Settings) → Annexes → Auto-start).
• 🔄 Activate the function RAM Extension (available on models with MIUI 12.5+ and external memory).
• 📱 For older devices: install Lite versions of apps (e.g. Facebook Lite, Messenger Lite).
• 🚀 Enable Performance Mode in Battery Settings.

Critical information: On some models (for example, Redmi Note 8 Pro) after upgrading to the MIUI 13 there is a memory leakage bug that causes the system to eat up to 80% of RAM into idle. MIUI 12.5 or manual firmware via Fastboot.

4.Battery problems: When the battery "dies" and pulls the system down

A worn-out battery is one of the most insidious causes of glitches, and when the battery capacity drops below 70 percent of the original battery capacity, the device starts:

• 🔋 Turn off at 20-30% charge (false indicators).
• 🐢 Brake at a charge level below 50% (system limits performance).
• 🔌 Do not charge or charge with jerks.

How to check the status of the battery:

1. Enter the code ##4636## and select Battery Information.
2. And look at Battery Health, which is critical, below 80 percent.
3. Use AccuBattery or Battery Guru for detailed diagnosis.

What to do:

• 🔄 If the capacity has dropped to 60-70%, consider replacing the battery:

If replacement is not an option, try:

• 🔌 Use a charge with less power (for example, 10W instead 33W).
• 📴 Disable background synchronization and geolocation.
• 🔋 Enable charge saving mode below 50%.

⚠️ Note: On models with a non-removable battery (for example, Xiaomi 13 or Mi 11), self-replacement is fraught with damage to the plumes.

5. Application conflicts: when software is “at war” with the system

Incorrect applications are a common cause of departures, freezes and overheating, especially in:

• 🤖 Applications with background services (messengers, social networks).
• 🎮 Games with aggressive optimization (e.g. Genshin Impact or GAI) PUBG Mobile).
• 🔒 Antivirus and cleaners (e.g. Clean Master, 360 Security).
• 📱 Launchers from third-party developers (for example, Nova Launcher, Microsoft Launcher).

How to identify the problem application:

1. Launch the device in Safe Mode (press the power button) → Safe Mode. If the glitches are gone, it's third-party software.
2. Check the error log in Settings → Memory. → Journal of remembrance.
3. Use it. ADB adb shell dumpsys meminfo (shows which processes eat away at memory).

List of apps that often cause conflicts on Xiaomi:

• 📌 Facebook and Instagram are known for memory leaks.
• 📌 Truecaller – can block incoming calls.
• 📌 Shareit and Xender – conflict with Mi Share.
• 📌 Google Play Services – sometimes “hangs” and loads the processor.

Decisions:

• 🗑️ Clear the cache and data of the problem application.
• 🔄 Reverse it to the previous version (via APKMirror).
• 🚫 Add to the blacklist in Settings → Annexes → Special access → Optimizing the battery.

💡

If the glitches started after installing a particular application, first check its permissions in Settings. → Annexes → Permissions: Applications with access to Special Opportunities or Overlays on top of other windows often cause problems.

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

If software methods fail, there may be physical damage to components, typical hardware malfunction symptoms:

The most vulnerable components in Xiaomi devices:

• 📱 Trains (especially in Redmi with a detachable body).
• 🔌 Charging connector (often loosened after a year of use).
• 🎤 Microphone and speakers (infection of moisture or dust).
• 📡 Antenna module (network problems) 4G/5G).

What to do:

1. If the device fell or got wet, do not turn it on - contact the service.
2. Check the warranty: it is valid for 12-24 months on most models.
3. For diagnostics, use test modes: For smartphones: ##6484## (display test) For Mi TV: Press Menu. → Support → Device Diagnostics

⚠️ Warning: If your Xiaomi or Redmi stopped turning on after a fall, don't plug it into charging - it could cause a short circuit.

7 Network problems: Wi-Fi, mobile internet and Bluetooth

Failures in wireless modules are a frequent complaint of Xiaomi users.

• 📶 Wi-Fi is connected, but the internet is not working.
• 📵 Mobile network disappears or switches to 2G.
• 🔊 Bluetooth is periodically disabled (especially in Mi Band and headphones).

Causes and solutions:

Additional advice:

• 🔄 Restart your router if Wi-Fi problems occur on multiple devices.
• 📱 For mobile network: Enable mode Only 4G customized SIM-map.
• 🔊 For Bluetooth: Turn off battery savings for connected devices.

If nothing works, it may be the motherboard's communication module that's to blame, and that's where the service needs to be diagnosed.
