But how exactly do you determine what was the trigger? About this in our detailed guide.

1. Processor overheating: the main cause of spontaneous rebuttals

Redmi Note 8 Pro is equipped with a productive chipset Helio G90T, It can overheat when you're under intense stress, and it can get hot if it's over 85 or 90.°C, the system forcibly restarts the device to prevent damage to the components. This is a defense mechanism, but it often works at the most uncomfortable times.

How to check for overheating? Install the app AIDA64 or CPU Monitor and run a load test if the CPU temperature rises above 75.°C in idle mode or 95°C is a critical indicator in games. Also note the following signs:

• 🔥 The body of the phone becomes hot even with minimal load (for example, when watching videos).
• 🎮 Reboots occur during games (PUBG Mobile, Genshin Impact, Call of Duty).
• 🔋 Fast battery discharge (more than 20% per hour on standby).
• 📉 Performance is falling, applications are starting to slow down".

If overheating is confirmed, try the following measures:

⚠️ Warning: Never use your phone on soft surfaces (such as a bed or couch) when it's connected to charging, blocking the vents and exacerbating overheating.

2. Battery problems: wear, bloating, short circuit

The battery is one of the most vulnerable components of the Redmi Note 8 Pro. Its average life is 2-3 years, after which the capacity drops, and the risk of spontaneous reboots increases. If the phone turns off at a charge level of 20-30% or suddenly restarts when charging is connected, the battery is to blame 90% of the time.

How to diagnose a battery failure:

• 📊 Check the battery status in Settings → Battery → Battery condition: If the capacity is below 80% of the original capacity, a replacement is required.
• 🔋 Connect your phone to charge and move the cable, and if the device reboots, the problem is the connector or the power controller.
• 🔍 Check the battery for bloating (if available), even a slight strain is a reason to replace it.

If the battery is swollen, immediately turn off the phone and do not use it until the battery is replaced.A bloated battery can damage the screen or motherboard, and in extreme cases, ignite.

The cost of replacing the battery in the service center is from 1500 to 2500 rubles. If you decide to change it yourself, buy only the original Xiaomi batteries with the labeling. BM47 (Cheap analogues can not only quickly fail, but also damage the power controller.

3. Firmware failures: errors MIUI and systemic conflicts

Software errors are the second most common cause of spontaneous reboots. MIUI, Despite regular updates, it sometimes contains critical bugs, especially in custom (unofficial) firmware.

Typical signs of software failure:

• 🔄 Reboots occur when specific applications are opened (e.g. cameras or galleries).
• 📱 On the screen there are messages like "The application system settings stopped".
• 🔄 The phone is rebooted when connected to Wi-Fi or mobile network.
• 📲 In error logs (Settings) → The phone. → Error Reports: There are records of kernel panic".

What to do:

1. Reset the settings to factory (Settings) → Additionally. → Recovery and reset) Pre-return the data!
2. Update MIUI to the latest version (Settings → About Phone → System Update).
3. Install firmware manually via Fastboot or Recovery (instruction below).
4. Remove the update if the problem occurs after it.

If the problem persists after a reset or update, the system partition (boot or system) may be damaged, in which case only a complete flashing through the Mi Flash Tool will help.

4. Motherboard malfunctions: short circuits and microcracks

Hardware motherboard failures are the most serious cause of reboots, most often occurring after:

• 💥 Falls or impacts (even if the phone is intact).
• 🌊 Moisture intrusion (corrosion of contacts).
• ⚡ Voltage surges during charging.
• 🔥 Overheating due to a faulty battery.

Symptoms of hardware malfunctions:

• 🔄 The phone reboots when vibrating or lightly pressing the body.
• 📵 There is no image on the screen, but the phone vibrates and makes sounds.
• 🔌 The charging doesn’t work or the phone turns off when the cable is connected.
• 📡 Wi-Fi or network disappears after restart.

Diagnosing the problems of the fee on your own is difficult, but you can check several points:

💡

If you push the bottom of the case, the battery socket is probably soldered off or the power track is damaged, and only soldering at the service center will help.

If you suspect a hardware malfunction, don't try to disassemble the phone yourself without experience. chip damage often requires professional equipment (sweeping station, microscope, BGA-The cost of repairing the board can reach 50-70% of the price of a new phone, so it is sometimes advisable to consider buying a new device.

5. Application conflicts: viruses, mining, poor optimization

Some applications can cause critical errors in the system, leading to a reboot.

• 🦠 Viruses and spyware (mining bots, keyloggers).
• 🎮 Unoptimized Games with High Demands.
• 📱 Applications for overclocking the processor or changing frequencies (for example, Kernel Adiutor).
• 🔄 Automatic cache cleaning programs (can delete system files).

How to identify the problem application:

1. Launch your phone in Safe Mode (press the power button) → "Safe Mode. If the reboots have stopped, third-party software is to blame.
2. Check the list of recently installed apps in Settings → Apps.
3. Use the Antututu Benchmark or CPU Monitor to track which application loads the processor before restarting.

Delete suspicious apps and scan your phone Malwarebytes or Dr.Web. If the problem is optimization, try:

• 🔄 Disable background activity for problem application (Settings) → Annexes → Permits → Background activity).
• 📉 Reduce the graphical settings in games.
• 🗑️ Clear the cache and application data.

💡

If the phone only reboots when you open one app (like a camera), try clearing the cache or reinstalling it. If that doesn't work, the driver problem (reflashing required).

Problems with RAM (RAM) storage

The Redmi Note 8 Pro was released with 6 or 8 GB of RAM, and if RAM is clogged with background processes or damaged, the system can crash to restart.

• 📱 Damaged Sectors of Internal Memory (eMMC).
• 🔄 Conflicts with a lack of free space (less than 1 GB).
• 🖥️ Errors in swap file operation (virtual memory).

How to check:

1. Open the Settings. → Memory and see how much space is left. If less than 10%, delete the unnecessary files.
2. Run a memory test through AIDA64 (section Tests → Memory).
3. Check the integrity of the file system through ADB: adb shell df -h adb shell dumpsys meminfo

If the tests show read/write errors, the memory chip may be damaged, in which case only the replacement of the board (cost - from 5000 rubles) will help.

• 🔄 Disable animation and background processes (Settings) → Developer → Limit background processes).
• 📱 Use the "Easy Mode" in MIUI (Settings → Screen. → Screen mode).
• 🗑️ Regularly clean the cache through Settings → Memory. → Clean up.

7.Problems with SIM-link-card
