How to check the temperature of the processor on Xiaomi Redmi Note 8 Pro: 5 working ways

Xiaomi Redmi Note 8 Pro with its powerful MediaTek Helio G90T processor and gaming accent often faces overheating — especially during long loads. But how do you know if your smartphone is really burning, or it’s just subjective? In this article, we will analyze all the ways to check the temperature of the chipset, from built-in tools to professional utilities, and also tell you what indicators are considered normal and which are critical.

It’s important to understand that overheating not only reduces performance, but also reduces the life of the battery and other components. For example, thermal throttling begins at temperatures above 85°C, and irreversible damage is possible at 100°C+. So temperature monitoring is not a whim, but a necessity for owners of the Redmi Note 8 Pro, especially if you are actively playing Genshin Impact, mounting videos or using the device in hot climates.

Why it is important to monitor the temperature of the processor

The Helio G90T processor in the Redmi Note 8 Pro is built on a 12nm process, making it more “hot” than modern 6-7nm chips, while the cooling system of the smartphone is limited — there is no liquid cooling or graphite plates, like in flagships.

• 🎮 Games (especially with high graphics settings in the PUBG Mobile or Call of Duty)
• 📹 Video recording in 4K or prolonged use of the camera
• 🔄 Multitasking (simultaneous work 10)+ applications)
• ☀️ External factors (direct sunlight, high humidity, thick material covers)

According to tests, the Redmi Note 8 Pro can heat up to 60-70°C on the body surface and 80-90°C inside (on the chip), which is close to the limit values after which the protection is triggered – the smartphone begins to “brake” or suddenly turn off.

⚠️ If the case of the smartphone is heated so that it is unpleasant to hold it in your hands (above 45)°C) and the battery is running out at 1-2% per minute, a sign of critical overheating. Close all applications immediately and let the device cool down!

Method 1: Integrated MIUI tools (without root)

Xiaomi has hidden direct access to temperature sensors in standard firmware, but there is a workaround through the engineering menu.This method does not require superuser rights and works on all versions of MIUI for the Redmi Note 8 Pro:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that appears, select Battery Information.
3. Scroll down to the Temperature unit, which shows the battery temperature, and for the processor, this method won't show you the exact data, but if the battery is heated above 40°C, then the chipset will overheat.

Unfortunately, the built-in engineering menu does not provide direct access to the CPU/GPU sensors, which will require third-party utilities (see the following methods), but you can check the status of the battery - if its health (Health) is below 80%, this indirectly indicates frequent overheating in the past.

Turn off the charger.

Close all background applications

Make sure your smartphone is not under direct sunlight.

Remove the cover (if any)

Method 2: Monitoring applications (CPU Monitor, AIDA64)

The most reliable way to get accurate data is to use specialized applications that read sensor readings through the Android API and display the temperature in real time.

The CPU Monitor is recommended, showing the temperature of each CPU core separately, which is critical for the Helio G90T (it has 2 powerful Cortex-A76 cores and 6 energy-efficient Cortex-A55 cores).

1. Launch the application and provide access to Settings → Special features (you need to display on top of other windows).
2. Go to the Temperature tab.
3. Pay attention to the lines. CPU Core 1 and CPU Core 2 is a hot core, and its temperature should not exceed 75-80.°C under load.

AIDA64 is less accurate, but it does show the temperature of the GPU (Mali-G76 MC4), which is as hot as the CPU in the Redmi Note 8 Pro.

1. Open AIDA64 and go to Sensors.
2. Scroll to the Temperature block.
3. Check the GPU and CPU values – if the difference between the two is greater than 15°C, this indicates heat sink problems.

Method 3: Through ADB (for advanced users)

If you're not afraid of the command line, you can get data directly through Android Debug Bridge (ADB), which doesn't require root, but you need minimal ADB skills and a computer.

1. Install ADB Tools on your PC.
2. Turn on USB Debugging on your smartphone: Settings → About Phone → MIUI version (click 7 times to activate Developer Mode), then go back to Settings → Additional → Developers → Debugging on USB.
3. Connect the Redmi Note 8 Pro to PC and enter in the terminal: adb shell cat /sys/class/thermal/thermal_zone*/temp
4. You will get a list of values in milligrades Celsius (divided into 1000 translating °C. For example, 75000 = 75°C.

The conclusion will be several zones:

• thermal_zone0 — battery
• thermal_zone1 or thermal_zone2 — processor (CPU)
• thermal_zone3 — graphics-processor (GPU)

⚠️ Attention: Some firmware MIUI block access /sys/class/thermal/ If the team returns a Permission denied error, try rooting or alternative methods.

Method 4: Through TWRP (only for unlocked bootloader)

If your Redmi Note 8 Pro has a custom TWRP receivers installed, you can check the temperature even without the system turning on.This is useful if the smartphone is not turning on due to overheating or getting stuck in the boot cycle.

1. Boot to TWRP (hold Power + Volume up when turned on).
2. Go to Advanced → File Manager.
3. Open the way. /sys/class/thermal/thermal_zone1/temp.
4. The screen will display the current temperature of the processor in milligrads.

This method also works to check the temperature when charging – if the smartphone is warming even when it’s off, the problem may be in the power controller or battery.

💡

If the TWRP processor temperature is above 60°C when the phone is off, it is a sign of a motherboard malfunction or short circuit.

Method 5: Physical check (to the touch and with thermometer)

Not always at hand is software for monitoring, in this case, you can assess the heating "by eye" and with the help of improvised tools:

• 🔥 Case: if the back cover next to the camera is hot (above 45)°C, this is a sign of the chipset heating up. If the bottom is warming, there's a problem with the battery or the charger.
• 📱 Screen: Yellowness or artifacts may appear when overheated (especially in games).
• ⚡ Charging: if the smartphone warms up when connected to the network, check the power supply – unoriginal charges often cause overheating.

For a precise check, use an infrared thermometer (costs ~500 rubles), point it over the back cover in the area of the processor (left of the camera) and compare the readings with the norm:

If the body temperature exceeds 50°C and the smartphone starts to turn off or reboot on its own, this is a sign of thermal shutdown, an emergency shutdown to prevent damage.

⚠️ Warning: Do not turn on the device until it is completely cooled (minimum 30 minutes). Repeated overheating can cause the battery to bloat or the motherboard to fail.

Temperatures for Redmi Note 8 Pro and what to do when overheating

Xiaomi has not disclosed the official temperature limits for the Helio G90T, but based on tests and data from MediaTek, the following standards can be derived:

• 🟢 No load: 30-45°C (CPU), 25–35°C (hull).
• 🟡 At moderate load: 45-60°C (CPU), 35–42°C (hull).
• 🔴 At high load: 60–75°C (CPU), 42–50°C. Exceeding these values requires intervention.
• ⚠️ Critical: above 75°C (CPU) 50°C (body): Risk of damage to components!

If your Redmi Note 8 Pro regularly overheats, try the following:

1. Clean dust: Use a soft brush to remove dust from the speaker and connectors (especially USB-C).
2. Remove the case: dense silicone or leather covers impair heat transfer by 10-15%.
3. Limit background processes: in Settings → Applications → Autorun, turn off autoboot for unnecessary programs.
4. Reduce the load: In games, reduce the graphics to Medium or Low. When shooting video, use 1080p resolution instead of 4K. Turn off Bluetooth, GPS and NFC if they are not in use.

Update the PO.

Settings → About the phone → System update

If overheating continues even after these measures, the problem may be:

• 🔋 Battery (swelling, wear and tear).
• 🛠️ Thermopaste (dried or applied incorrectly).
• 🔌 Charging device (non-original power supply unit).

💡

If the smartphone is warming even in standby mode (screen is off, applications are closed), this is a sign of hardware malfunction. You can not solve the problem yourself - you need a diagnosis in the service center.
