If your Xiaomi, Redmi or Poco starts spontaneously rebooting in a loop, itโs not just an annoying glitch, but a signal of a serious problem, a behavior that could indicate critical firmware failures, hardware malfunctions, or even malware. In 80% of cases, the problem is solved without visiting a service center, but itโs important to properly diagnose the cause.
In this article, we will examine all possible causes of cyclical reboots on Xiaomi, from banal overheating to damage to the motherboard. You will learn how to distinguish a software failure from hardware, what manipulations can be done yourself, and when you should immediately contact specialists. We will pay special attention to the Redmi Note models. 10/11/12, Poco X3/X4 Xiaomi 12/13 โ They are more likely to suffer from this problem due to the features of the firmware MIUI.
1. overheating of the processor as the most common cause
More 60% cases of spontaneous reboots on Xiaomi are associated with overheating of the chipset.Modern smartphones (especially with Snapdragon processors) 8 Gen 1/2 or Dimensity 9000) They're prone to heat trottling, when the temperature reaches 85-90ยฐC, the system forcibly restarts the device to prevent damage.
How to check:
- ๐ฅ Use the app. AIDA64 or CPU Monitor for temperature monitoring. Normal: up to 60ยฐC in plain, up to 75.ยฐC under load.
- ๐ฑ Check if the battery is swelling (take a smidge on the back cover carefully - if there are bulges, it is dangerous!).
- ๐ฎ Run a resource-intensive app (like Genshin Impact or Call of Duty Mobile) and observe your behavior.
โ ๏ธ Warning: If the phone overheats even in standby mode (e.g., lying on a table with the screen off), it may indicate a short circuit on the motherboard!
Decisions:
- ๐ ๏ธ Replace the thermopaste (relevant for models over 2 years old) on the Redmi Note 10 Pro and Poco F3 You can do it yourself.
- ๐ Reset the settings to factory through Settings โ The phone. โ Reset settings (pre-do backup!).
- ๐ด Turn off the background activity of applications in Settings โ Battery โ Optimizing the battery.
2. firmware failures and update conflicts
Unstable versions MIUI โ The second most common cause of cyclic rebukes:
- ๐ฑ Xiaomi 12/12T/12S on MIUI 14 (version 14.0.5.0 had a critical kernel bug)
- ๐ฑ Redmi Note 11 Pro+ 5G After upgrading to Android 13
- ๐ฑ Poco X3 Pro with custom firmware like Pixel Experience
Symptoms of programmatic failures:
- ๐ Reboots occur at regular intervals (e.g., every time). 10-15 minute).
- ๐ฑ On the screen before the reboot appears the message "Android system stopped".
- ๐ง In logs (Settings) โ The phone. โ Error Reports: There are records of "kernel panic" or "watchdog timeout".
How to fix it:
- Update your firmware to the latest stable version via Settings โ System Update.
- If the update doesnโt help, perform a clean installation. MIUI via Fastboot: fastboot flash all [name file firmware].tgz
- For advanced users: roll back to the previous version MIUI with the Mi Flash Tool.
How to check the integrity of the firmware?
Battery problems: when replacement is needed
A worn or damaged battery can cause spontaneous reboots due to:
- ๐ Power drawdowns (the battery does not hold the charge, the phone turns off when the battery is powered down) 30-40% charge).
- ๐ฅ Short circuit in the banks of the battery (dangerous! can lead to fire).
- ๐ Incorrect calibration (the phone shows 100% charge, but suddenly shuts down).
How to diagnose:
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The phone turns off at 20-30% charge. | Battery wear (capacity) < 70%) | Battery replacement |
| Reboots when connecting charging | CZ in a battery or power controller | Diagnostics in the service |
| Heating the battery in simple | Bloating of cans or damage to the thermosensor | Immediate replacement! |
| Cyclical rebuttals for 15-20% charge | Wrong calibration | Resetting battery data via #4636## |
โ ๏ธ Warning: If the battery is swelling, don't try to puncture or bend it! Lithium-ion batteries can ignite if damaged. Take the phone to service or dispose of the battery according to local regulations.
Instructions for calibration of the battery:
Charge the phone before 100%|Turn off the charging and use until full discharge (0%)|Connect the charger and wait. 100% non-interrupted|Repeat the cycle 2-3 once-->
4. Application conflicts and malware
Some applications (especially root-access or modified ones) APK) They can cause critical kernel errors, leading to reboots:
- ๐ฎ GameGuardian, Lucky Patcher)
- ๐ VPN-Applications with non-standard protocols (Psiphon, some versions of NordVPN)
- ๐ฑ Launchers from third-party developers (Nova Launcher, Microsoft Launcher)
- ๐ฆ Viruses masquerading as system utilities (e.g., "com.android.system.update")
How to find a problem application:
- Launch your phone in Safe Mode (hold the power button) โ long tap on "Switch off" โ "Reboot to Safe Mode").
- If the reboots have stopped, it's the third-party software's fault. Remove the last apps installed.
- Check your phone for viruses with Malwarebytes or Dr.Web Light.
List of dangerous permits that may cause failures:
- ๐จ REQUEST_INSTALL_PACKAGES (installation)
- ๐จ BIND_ACCESSIBILITY_SERVICE (access to special opportunities)
- ๐จ WRITE_SECURE_SETTINGS (change of system settings)
๐ก
If you can't find the guilty application, check the logs through adb logcat "FATAL EXCEPTION" or "Bootloop".
Hardware malfunctions: from plumes to motherboard
If the software methods didn't work, the problem is probably hardware.
Damaged plumes:
- ๐ถ The antenna plume (can close on the body when falling).
- ๐ Battery plume (oxidation of contacts).
- ๐ท Camera plume (on Xiaomi models) 11T Pro and Redmi. K50 fling away).
Malfunctions of the motherboard:
- ๐ฅ Burnt capacitors near the processor (seen by the blackened areas).
- ๐ง Liquid intake (even if the phone didn't sink, moisture could condense inside).
- ๐ Damage to power chains (phone only switched on from charging).
Diagnosis:
- ๐ Examine the phone for physical damage (cracks, dents, traces of oxidation).
- ๐ง Connect headphones โ if the sound is distorted or missing, the audio chip may be damaged (Qualcomm) WCD9385).
- ๐ก Check the work. GPS If the signal goes missing, there's a problem with the antenna plume.
โ ๏ธ Warning: If the phone reboots when connecting to a computer or charging, it may indicate damage to the controller USB Type-C (a common Poco problem) X3 NFC Self-repairing requires a soldering station and experience!
6. Conflicts after firmware or unlocking the bootloader
If you've recently:
- ๐ Unlock the bootloader through the Mi Unlock Tool,
- ๐ฑ They've installed a custom Recovery (TWRP, OrangeFox),
- ๐ Unofficial firmware (LineageOS, HavocOS),
The reason for the reboot may be:
Incompatibility of firmware with iron:
- ๐ฑ Firmware for Redmi Note 10 is installed on Redmi Note 10 Pro (different chipsets!).
- ๐ Version. MIUI does not correspond to the region (for example, MIUI Global on the phone for China).
Errors when unlocking the loader:
- ๐ VBmeta or DM Verity incorrectly installed.
- ๐ฑ There's no file. disable_dm-verity_forceencrypt into /vendor.
Decisions:
- Return to stock firmware via Fastboot: fastboot flash boot boot.img fastboot flash system system.img
- Check the integrity of the firmware files (MD5-Hashes must match official hashes).
- If you used Magisk for root, try removing all modules through Magisk Manager.
๐ก
After unlocking the bootloader, always install the firmware that matches your model code (e.g., Redmi Note 11 Pro). 5G The Redmi Note 11 Pro has the code veux, and the code mismatch will lead to cyclic reboots!
7.Memory problems: eMMC and UFS near-death
If the phone reboots when writing files (for example, when shooting a video or installing apps), the memory is to blame.
- ๐ฑ Apps suddenly close with the error "Storage may be corrupted".
