Owners of modern smartphones Xiaomi, Redmi and POCO often face a situation when the device begins to warm significantly during games or video shooting. CPU temperature is a critical indicator that affects system performance and battery life. Control over thermal mode prevents trottling (forced frequency reduction) and extends the life of the gadget.
In this article, we will detail how to accurately know the current CPU heating rates using both built-in tools and third-party software. You will learn to distinguish normal working heat from critical, requiring intervention. Understanding these processes is essential for anyone who wants to get the most out of their device without the risk of overheating.
Why it is important to control the heat of the processor
Modern mobile processors, whether powerful Snapdragon or powerful MediaTek Dimensity, generate significant amounts of heat under load. If the heat sink fails, the system automatically lowers the clock speed to avoid chip damage, manifested in sharp drops in FPS in games and delays in the interface.
Constant operation at high temperatures negatively affects the chemistry of the lithium polymer battery. The electrolyte inside the battery degrades faster, leading to bloating or a sharp drop in the capacity. Regular monitoring allows you to detect anomalies in time and take cooling measures.
💡
The critical threshold for most Xiaomi processors is considered to be temperatures above 45-50 ° C in idle, although under load it can reach 60-70 ° C without fatal consequences.
Also, knowing the exact temperature helps to identify background processes that unnecessarily strain the system, sometimes not due to play, but due to a “hung” service or MIUI malfunction.
Built-in diagnostics MIUI and HyperOS
Xiaomi shells provide basic tools for monitoring the status of the device, but it is worth noting that the standard interface often hides detailed technical data, showing only general statuses like “normal” or “dangerous”.
For more accurate information, you can use the engineering menu, which is accessed through a standard phone dialer. Enter the code ##6484## to enter CIT mode (Customer Integration Test), Here you can find battery and processor tests that show the current state of the sensors.
What if the code doesn't work?
There's also a Battery section in the Safety app that shows the approximate heating level, and although the numbers can be rounded, the color indicator (green, yellow, red) gives you a quick sense of the situation, and if the light is on red, you'd better close heavy applications.
Third-party applications for accurate monitoring
If there's not enough built-in tools, Google Play's specialized tools come to the rescue, and they can read data directly from the thermistor sensors on the motherboard, and they can show the temperature of each core of the processor separately.
One of the most popular and reliable tools is CPU-Z. This app is free and does not require root rights. After installation, go to the Thermal tab, where real-time readings from different areas of the chip will be displayed. Also worth paying attention to AIDA64 or 3DMark, which provide detailed graphics.
For professional diagnostics, it's better to use software that can plot temperature over time, which will help you understand how quickly the device heats up and cools down.
Temperature check through ADB teams
For advanced users who want to access raw data without installing any unnecessary apps on their phone, the Android Debug Bridge (ADB) tool is ideal, which allows them to see the exact values from all the system sensors in real time on a computer screen.
First, you need to activate the USB debugging mode in the Developer menu and connect the smartphone to the PC. Once you install the drivers and set up the ADB, execute a command to output a list of all temperature sensors, which will give a complete picture of the thermal state.
adb shell cat /sys/class/thermal/thermal_zone*/tempThe result of the command is a list of numbers. In Android, the temperature is usually transmitted in milligrads, so the resulting number should be divided by 1000. For example, a value of 45600 means 45.6 ° C. Find the lines containing the words "cpu", "battery" or "skin" to navigate.
💡
Use the adb shell dumpsys battery command to get summary information about the battery status, including its current temperature, without having to parse files. thermal_zone.
This method is especially useful if the phone screen is busy playing and you want to monitor the heating on the second display.The script can be run in a loop so that the values are updated automatically every second.
Temperature standards and table of values
Understanding which metrics are considered normal and which require alarm helps to avoid panic.CPU temperature depends on the current task and environmental conditions. Below is a table of indicative values for Xiaomi processors.
| Status of the device | Temperature (°C) | Status of the system |
|---|---|---|
| Simple (screen off) | 25 – 35 | Perfect. |
| Social networks, browser | 35 – 42 | It's okay. |
| Hard games, rendering. | 43 – 55 | Working heat |
| Charging fast | 40 – 50 | Permissible. |
| Critical overheating | Above 60. | Dangerous/Trottling |
It’s worth considering that the skin temperature sensor, which often shows the interface, is always below the actual temperature of the CPU crystal.The heat has to pass through the heat pads and the screen, so the real Temp CPU can be 5-10 degrees higher than what you see in the status bar.
⚠️ Warning: If the temperature in downtime (without running applications) is stable above 40°C, this may indicate a battery malfunction or background viral mining.
How to reduce the temperature during overheating
If the monitoring has shown critical values, you need to immediately reduce the load on the SoC (system on a chip), the easiest way is to remove the protective case, as it often works as a thermal insulator, preventing the natural cooling of the case.
Close all background applications through the task menu, and you can activate the battery settings to save energy, which will limit the maximum CPU frequency and screen brightness, which will temporarily reduce performance, but will help to quickly cool the device.
☑️ Emergency cooling
In extreme cases, when the device is hot to the point where it is painful to hold in your hands, it is better to turn it off completely and put it on a cool (not cold!) surface. The use of a refrigerator or freezer is strictly forbidden - the condensation inside will kill the electronics.
