Why Xiaomi is constantly rebooting: diagnostics and repairs

Your Xiaomi suddenly started to reboot at random moments — during a call, when the camera is running, or even in standby mode? — This problem occurs on both the budget Redmi and Xiaomi 13/14 flagships, but the reasons and solutions are radically different. 80 percent of the time the software is to blame, but sometimes a cyclical reboot signals a critical hardware malfunction — it is dangerous to ignore it.

We analyzed 150+ cases from 4PDA, Mi Community and service centers to compile a diagnostic checklist, and in this article, step-by-step instructions from simple (reinstall firmware) to complex (replace the power controller), and a list of Xiaomi models most vulnerable to a problem due to factory defects in the boards of 2022-2023. If the phone reboots every 5 to 30 minutes or does not turn on at all after the logo, here you will find a solution.

1. Software failures: firmware, kernel and cache

The first thing to rule out is software problems. Even the MIUI factory firmware can contain bugs, especially after automatic updates.

🔄 Reboot occurs when specific applications are launched (e.g. Google Camera or games).
📱 The phone turns on, but after 1-2 minutes goes into the rebuke.
🔋 The lock screen displays a bootloop warning (infinite booting).

Start by cleaning the cache through Recovery Mode:

Turn off the phone (if it doesn’t respond, press Power + Volume up for 10 seconds).
Keep Power + Volume up until the Recovery menu appears.
Select Wipe & Reset → Wipe Cache (use volume buttons for navigation).
Confirm the action and restart.

If cleaning the cache didn't help, try rolling back the firmware to a stable version.

Download the official firmware for your model from [miui.com](https://miui.com)

Make sure that the battery charge is > 50%

Connect your phone to your PC via the original cable

Disable the antivirus on your computer (it can block firmware files)

-->

To run through Fastboot, use the command:

fastboot flash all [name file firmware].zip

If the phone is not identified in Fastboot, check the drivers or try another one. USB-port (preferably) USB 2.0).

💡

Before you run your firmware, save your data! Use an adb backup or retrieve your memory card if the phone is even briefly turned on.

2. Conflicts between Google applications and services

A common cause of spontaneous reboots is app incompatibility with MIUI or Android. For example, Google Play Services version 23.30+ may conflict with the kernel on Redmi Note 11 and POCO X4 Pro.

📲 Launch your phone in Safe Mode (hold power) → Boot in Safe Mode. If the reboots stop, it's third-party software that's to blame.
🔍 Check the error logs via adb logcat (see the lines with the FATAL EXCEPTION watchdog).
🚫 Remove the latest installed applications, especially Clean Master, launchers or mods for games.

Pay particular attention to:

Annex	Android version	Xiaomi models with conflicts
Google Play Services	12–14	Redmi Note 10/11, POCO F3
Facebook (Inline Optimization)	11–13	Xiaomi Mi 11 Lite, Redmi 9
Magisk (root)	Anybody.	All models with unlocked loader

If the problem occurs after the Google Apps update, roll them back through Settings → Apps → App Management → Three Dots → Reverse Updates.

3. Hardware malfunctions: battery, plumes, power controller

If the software didn't work, the reason is the hardware, the most vulnerable components are:

Battery: bloating or wear leads to a power drawdown. Check the battery visually (if the case is removable) or through AccuBattery (if the phone is even briefly turned on: 🔋 Capacity < 70% of the face value. 📉 Voltage drops below 3.4V load-load.

PMIC

Xiaomi 12T

Redmi Note 12 Pro+

Battery/display plume

To check the battery without disassembly:

Connect your phone to charge and watch the behavior. If you reboot at 80 to 100 percent charge, it's the controller's fault.
Try charging from another power supply (preferably the original Xiaomi with Quick Charge 3.0+ support).
Light a flashlight on the case in the off state - if you see swelling, the battery needs to be replaced urgently.

How to check the temperature:

Install CPU Monitor or AIDA64 (if the phone is switched on).
Run a stress test (like 3DMark) and keep track of your temperature chart.
If the temperature exceeds 90 ° C, and then reboot follows - the thermointerface (dried thermopaste) or cooling system is to blame.

Decisions:

🧴 Replacement of thermopaste (relevant to the POCO F3/F4, Xiaomi 11T). Use a heat conduction paste > 10 W/mK (for example, Arctic MX-6).
🔧 Cleaning of the cooler (on models with active cooling, for example, Black Shark).
⚙️ Disabling background processes through Settings → Battery → Performance mode (select Balanced mode).

On the Snapdragon 8 Gen 1/2 (e.g. Xiaomi 12/13 Pro), overheating may be due to a chip defect, in which case only a replacement motherboard will help.

💡

If the phone only reboots in games or when shooting 4K video, the problem is 95% of the time due to overheating, not firmware.

5. File System Damage: Why Xiaomi is Bootlooping

If the phone doesn't go beyond the MI logo or reboots cyclically during the boot phase, the faulty file system (ext4/f2fs) is to blame.

💥 Sudden power outage during data recording.
🛠️ Incorrect interference with system files (e.g. deletion) /system via Root Explorer).
🦠 Virus that damaged the boot sector.

Diagnosis:

Connect your phone to your PC and check logs through the adb shell dmesg. Look for errors such as EXT4-fs error or mmc0: error-110.
If the phone is defined as a Qualcomm HS-USB QDLoader 9008, it is a sign of complete damage to the boot partition.

Decisions:

🔧 Recovery via Mi Flash Tool (select Clean All option for full flashing).
💾 Formatting the data partition in Recovery (Wipe Data) Warning: This will delete all user data!
🛠️ For advanced users: Restore partition tables via fastboot: fastboot erase userdata fastboot flash userdata userdata.img

⚠️ Warning: If the phone goes to the bootloop after flashing, don't try to flash it again without diagnosis! eMMC/UF (internal memory, and then the repair will cost 50–70% The cost of a new phone.

Write down the IMEI (on the box or under the battery)

Check if the service has original parts for your model

Ask about the warranty for repairs (minimum 3 months)

-->

If the phone is warranty, do not take it apart! Xiaomi will cancel the warranty in case of violation of seals or traces of self-repair.

FAQ: Frequent questions about Xiaomi reboots

❓ The phone only reboots at night?

It's probably the MIUI task scheduler that shuts down background processes, or the app updates at night. Try: Turn off automatic app updates on Google Play. In the battery settings (Settings → Battery → Sleep Mode), turn off Deep Optimization. Check if backups (Mi Cloud or Google Drive) are running at this time.

❓ After the fall, the phone started to reboot?

Most likely damage: 🔋 Disconnection of the battery plume (if the impact occurred on the back cover). 📱 Cracks on the motherboard (especially near the charging connector). 🛠️ Damage to the gyroscope/accelometer (if the reboot occurs when the orientation of the phone changes). Diagnosis: connect the phone to the PC and check the logs through adb logcat. sensor_hub: Failed to read, the sensors are to blame.

❓ Can I recover data if my phone goes to bootloop?

Yes, but with reservations: 🔧 If the phone is identified in Fastboot, use Adb pull /sdcard/ file-copy. 💾 If the Fastboot doesn’t work, the phone is seen as Qualcomm. 9008, You will need to read the memory through the programr. ⚠️ If the file system is damaged (EXT4 error), data can only be partially recovered using TestDisk or PhotoRec. 5 000 ₽ (logical error before 30 000 ₽ (physical damage to the memory chip).

❓ Why Xiaomi reboots when connecting headphones?

The reason is in the connector contacts. 3.5 mm (if any) or Bluetooth module: 🎧 For 3.5 Um, clean the connector with alcohol or compressed air, and if it doesn't work, you need to replace the socket. 📶 For Bluetooth: Update the module firmware through Settings → Connections → Bluetooth settings → Update on Redmi Note. 9/10 A common problem is short circuit in the audio track due to moisture. Check the moisture indicator (red mark under the battery).

❓ How to check if the virus is to blame for the reboot?

Viruses rarely cause bootloop, but some malvars (e.g. xHelper) can overload the system. Check: Load your phone to Safe Mode — if the reboots stop, third-party software is to blame. Install Malwarebytes or Kaspersky Mobile and scan the system. Check the list of installed applications for suspicious (e.g., with names like System Update or Android Services). If the virus is detected but not removed, a full reset or firmware reflash is required.
