Xiaomi Reboots Often: Why It Happens and How to Fix It

If your Xiaomi smartphone starts spontaneously rebooting, it’s not just an annoying glitch, it’s a signal of a serious problem, and this behavior can indicate both software failures (from application conflicts to damaged firmware) and hardware malfunctions (overheating, battery wear or motherboard damage), and 80% of the time, you can solve the problem yourself without resorting to a service center – but you need to pinpoint the root cause.

In this article, we’ll look at all the possible reasons for Xiaomi’s frequent reboots (including Redmi models, POCO And the flagship series, we'll offer step-by-step instructions for diagnosing and troubleshooting, and we'll also tell you where you can't do without the help of specialists. MIUI, which can provoke cyclic rebukes, and typical user errors when trying to repair yourself.

1. CPU overheating: why Xiaomi is shutting down and rebooting

One of the most common causes of spontaneous reboots is thermal throttling (automatic shutdown at critical temperature). Xiaomi with Snapdragon or Mediatek processors, protects against heating above 70-85°C (threshold depends on model) If the smartphone reboots during games, shoot video in the video. 4K Or charging - it is the overheating that is to blame.

How to check the temperature:

• 📱 Install the app AIDA64 or CPU Monitor from Google Play.
• 🔥 Check the indicators in the Sensors section → Temperature. CPU.
• ⚠️ Critical values: >65°C to the plain, >80°C under load.

What to do:

• 🧊 Remove the case (especially silicone) - it worsens heat transfer.
• 🔌 Do not use your phone while charging (especially fast).
• 🎮 Limit it. FPS in games through settings → Special facilities → Permission and frequency of staff.
• 🛠️ Replace thermopaste (relevant for models over 2 years old).

⚠️ Warning: If the temperature is above 90°C in plain is a sign of a malfunction of the cooling system or motherboard. Immediately stop using the device and contact the service.

2. Battery problems: wear, bloating, non-original batteries

The battery is the second most common culprit for sudden reboots. According to service centers, 60% of Xiaomi smartphones older than 3 years have a worn battery with a capacity below 70% of nominal value.

• 🔋 The phone turns off at 20-30% charge, although the indicator shows a normal level.
• 🔄 Reboots occur when connecting / disabling charging.
• 💥 The body swelled (seen by the divergence of the seams or the bulge of the screen).

How to check the status of the battery:

1. Enter the phone code ##4636##.

If the capacity is below 70% and the phone reboots at 15-40% charge, this is a classic symptom of a power drawdown, the battery can't provide enough current, and the system is forced to be recharged, and the solution is one: replace the battery (original or certified analogue).

💡

Before you replace the battery, make a full backup of data. Low-quality batteries can damage the power controller, which will lead to the complete failure of the phone.

3. Firmware failures and conflicts MIUI: How to Correct Programming Errors

Operating system MIUI (Especially in versions 12-14) is known for its bugs, which can cause cyclic reboots:

• 📲 Firmware updates “over the air" (OTA).
• 🔄 Reset to factory settings without cleaning the cache.
• 🛠️ Installation of custom themes or launchers.
• 📦 Conflict of system and user applications.

Diagnosis:

1. Launch your phone in Safe Mode (hold the power button) → long tap on "Switch off" → "Restarting in Safe Mode").
2. If the reboots have stopped, it's the third-party app's fault.
3. If the problem remains, the failure is in itself. MIUI.

Solutions:

For models POCO You can try to use custom firmware (e.g. Pixel Experience or LineageOS) with an unlocked bootloader and Redmi, but this voids the warranty and requires technical skills.

⚠️ Note: If the phone is rebooted on the logo MI (bootloop, don't try to flash it through Fastboot without backup! it can lead to a total loss IMEI and "bricking" of the device.

4. Application conflicts: how to find and remove the "culprit"

Even one "curved" application can cause kernel panic, which is a system reboot, and it's often the fault of:

• 🎮 Games with aggressive optimization (e.g. Genshin Impact, PUBG Mobile).
• 🔒 Antivirus and cleaners (e.g. Clean Master, 360 Security).
• 📱 Launchers and widgets (especially Nova Launcher with plugins).
• 🔄 Applications for automatic brightness/sound control.

How to find a problem application:

1. Go to Settings → Applications → Application Management.
2. Sort by installation date (recently installed).
3. Remove suspicious programs (starting with the latter).
4. Check out reviews on Google Play – users often write about such bugs.

If the phone reboots when you open a particular app (like a camera or gallery), try:

• 📌 Clear cache and application data.
• 🔄 Reverse it to the factory version (in the application settings).
• 📥 Install APK from another source (e.g. APKMirror).

5. Hardware malfunctions: what breaks down in Xiaomi most often

If the software methods didn't work, the problem is the hardware. TOP-5 hardware reasons for Xiaomi reboots:

Independent diagnosis of "iron":

• 🔍 Light a flashlight on the motherboard (with the phone disassembled) - look for blackened or bloated capacitors.

• 📱 Try to start the phone without SIM-Memory cards and cards – sometimes contacts are closed.

⚠️ Warning: If the phone reboots when connecting to a computer or charging, don't use it until repaired! this could be a sign of a short circuit that will cause a failure. USB-port.

6. Viruses and Malware: Hidden Threats

Malware rarely causes reboots, but it cannot be completely eliminated, especially if:

• 📲 The phone started to brake and restart after installation APK unverified.
• 🔗 There are strange banner ads or redirects in the browser.
• 📊 Traffic consumption is increasing inexplicably (check in Settings) → SIM-maps and mobile networks → Traffic).

How to check your phone for viruses:

1. Install Malwarebytes or Kaspersky Mobile.
2. Start a deep scan (not fast!).
3. Check the list of applications with Administrator rights (Settings) → Passwords and security → Administrator rights).

If threats are found:

• 🗑️ Remove infected applications.
• 🔄 Reset the settings to factory (with internal memory cleanup).
• 🛡️ Install a reliable antivirus (e.g. Bitdefender Mobile Security).

Especially dangerous are malware masquerading as system applications (e.g. com.android.system or com.qualcomm.telephony), which can block access to settings and cause reboots when you try to remove them, in which case only a complete reset or flashing will help.

7. problems with the memory card or SIM: non-obvious

Few people know, but a damaged microSD or a faulty one. SIM-The card can cause system failures, up to reboots, due to the fact that Xiaomi is actively using external drives to caching data.

2. Format microSD on your computer (file system) FAT32 exFAT).
3. Try another one. SIM-card (especially if you use an old, cropped under nano-SIM).

For Xiaomi models with a hybrid slot (such as the Redmi Note 10 Pro) it is important to:

• 📌 Do not use the microSD class below A1 (They're slowing down the system).
• 🔧 Regularly check the slot contacts for oxidation (clean with alcohol).

💡

If the phone reboots when it connects to Wi-Fi or a mobile network, the problem may be a faulty communication module, a hardware malfunction that needs repair.

8.When to contact the service: signs of serious breakdowns

If you’ve tried all the methods, but Xiaomi is still rebooting, it’s time to turn to the experts.

• 🔥 The phone is heated in the off state (battery or motherboard).
• 💥 Reboots are accompanied by cotton or sparks (risk of fire!).
• 📵 Phone does not turn on after reboot (possibly burned power controller).
• 🔧 Artifacts or stripes appear on the screen (GPU issues).
• 📡 Lost. IMEI or the phone does not catch the network (the communication module is damaged).

Cost of repairs in Xiaomi service centers (example prices for Russia, 2026):

Before the service visit:

⚠️ Warning: If the phone is warranty, don't open it yourself and flash it through Fastboot! this will void the warranty.
