How to check the temperature of the Xiaomi phone processor

Modern smartphones line Xiaomi, Redmi and POCO have a powerful “iron”, which under load can heat up to significant values. Understanding how to check the temperature of the processor, is necessary not only for enthusiasts, but also for ordinary users who notice a quick discharge or lag in the interface. Thermal throttle – a protection mechanism that reduces performance when overheating – can significantly worsen the experience of using the device if not tracked in time.

MIUI or the new HyperOS doesn't always have an obvious button to display this data on the home screen, but there are several proven diagnostic methods, from hidden engineering menus to installing specialized software, and it's important to distinguish between normal operating range and critical values at which hardware is at risk.

In this guide, we will look at all the ways you can get accurate data about the thermal state of SoCs, learn how to use hidden codes, which applications provide the most reliable information, and why a standard task manager does not always show the real picture.

Engineering menus and hidden codes

The fastest way to access technical information is to use hidden information. USSD-In the shell of the teams. MIUI The developers left access to the engineering menu, which allows you to diagnose various modules, including: CPU. To enter, you need to open the standard "bell ringer" and enter a special code. Most devices have the code ##6485##. Once you enter the last character, the menu will open automatically, without the need to press the call button.

In the list that you open, you'll find the lines that contain the information about the voltage and the temperature. MB_06 (the current battery temperature, which indirectly indicates the heating of the housing; or RF_05 (However, the most accurate information about the processor is often hidden elsewhere or may not appear on some firmware modifications. If the code does not work, it is possible that your version of Android or regional firmware is blocking access to this menu.

⚠️ Note: In the engineering menu, it is forbidden to change the values of parameters marked as writable unless you know exactly what they are responsible for. Accidental activation of test modes can lead to incorrect operation of communication modules.

It's worth noting that newer versions of HyperOS may have limited access to some diagnostic codes for security reasons. If the standard code didn't work, try alternative ##4636##, which opens the testing menu. You should select Phone Information and scroll down the list. Although this method is more commonly used to set up networks, it sometimes contains hardware status data.

Use of monitoring applications

The most informative and convenient way for the average user is to install specialized applications from Google Play. Standard tools of the system often show averaged values, while third-party software can read data directly from thermoprobe sensors. The leader in this category is the CPU Throttling Test application or CPU-Z.

After installing the CPU-Z, go to the Thermal tab, where you will see a list of all available temperature sensors. For the Xiaomi processor, values labeled as Battery, SoC or CPU are important. The app shows not only the current value, but also the history of changes, which allows you to track the dynamics of heating during games or heavy applications. AIDA64, which provides detailed information about each core, is also useful.

• 📱 CPU-Z — Classical instrument that shows the frequency, architecture and heat in real time.
• 🌡️ Device Info HW — App for advanced users, able to read specific sensors specific models Xiaomi.
• 📊 AIDA64 — Provides a complete report of the “iron” including the voltage and temperature of each component.

It's important to understand the difference between battery temperature and CPU temperature. The battery heats up more slowly and cools down longer, whereas the CPU can jump to 80°C in seconds under load and cool down just as quickly. Apps help separate these data streams. If you see the SoC temperature consistently staying above 45-50 degrees in idle, that's cause for concern.

💡

To get the most accurate data, run monitoring, close all background apps, and leave your phone on the table for 5-10 minutes, which will show the base temperature at rest.

Checking through MIUI and HyperOS settings

The built-in optimization tools in Xiaomi smartphones can also provide insight into the state of the system, although they don’t always show the exact temperature in degrees. The Safety app (green lightning icon) has a section called Optimization. When you run the check, the system analyzes the condition of the device. If the phone overheats, you will see a high temperature warning.

Newer versions of the HyperOS shell have added the Advanced Statistical feature in the battery settings. Go to Settings → Battery → Battery status (the path may vary depending on the version). Here you can see which applications are most energy-driven and cause heat. Although the degrees are not specified here, indirect consumption analysis helps identify the culprit.

Also worth noting are widgets. Device Status widgets are available in some themes and versions of MIUI, which can provide a brief summary of CPU workload, but are not the primary diagnostic tool, as they often work incorrectly or require constant updates.

Diagnostics through computer and ADB

For users who need maximum accuracy and who do not want to clog the phone with extra software, the ideal solution is to use debugging. ADB (Android Debug Bridge. This method allows you to read data directly from the system files of the kernel, which is not always available to ordinary applications, USB-cable and installed drivers ADB.

First, activate the developer mode. Go to Settings → About Phone and quickly click on MIUI 7 times. Then, in the advanced settings, turn on “Debugging USB.” Connect the phone to your PC and enter a command to access the shell interface: adb shell. After a successful connection, you can request temperature data.

cat /sys/class/thermal/thermal_zone*/temp

This command will list the temperatures of all zones, and the values are usually in milligradus (e.g., in the form of a temperature, 45000 signifier 45.0°To find the processor, you need to analyze the output or use the command cat. /sys/class/thermal/thermal_zone0/temp (The zone number may vary from model to model, and this is the most reliable method, since it takes data directly from the core of the system without intermediaries.

⚠️ Attention: When working with ADB Be careful, entering the wrong commands in root or shell mode can lead to unstable operation of the system. Use only read commands (cat) if you are not sure of your actions.

Normal and critical temperature values

Understanding the numbers is key. The Snapdragon and MediaTek processors that Xiaomi installs have their own temperature norms. At rest, the temperature is between 30°C and 40°C. If the phone is on the table and not in use and the temperature is above 45°C, it may be that the background process is eating up resources or the battery has degraded.

Under load (games, video rendering, system updates), the temperature can rise to 50-60 ° C. This is the operating range at which the trottling is not yet turned on at full power, but the case can already be significantly warmed. The critical area is considered to be values above 70-75 ° C. When you reach 80 ° C, most modern Xiaomi smartphones forcibly reduce the brightness of the screen and processor frequency, and at 85-90 ° C can be turned off to prevent damage.

• 🟢 30-40°C – Ideal condition, phone cold or slightly warm.
• 🟡 45-55°C – Heating under load, normal for heavy play or fast charging.
• 🔴 60°C+ — High temperature, it is recommended to remove the case and stop active use.

It is worth considering that the battery sensor often shows a lower temperature than the CPU sensor. So if the application shows 45 ° C on the battery during the game, the processor can be heated to 60 ° C. Always focus on the maximum values that you see in the reports.

💡

Short-term temperature jumps to 60-65°C during the launch of “heavy” games are not dangerous for a modern smartphone, if they are quickly replaced by stabilization.

What to do when the processor overheats

If the diagnostics show that your Xiaomi is constantly in critical mode, you need to take action. First of all, eliminate external factors: thick silicone cases do not remove heat; Remove the case during games or charging; Also check if the phone is not warmed in the sun - direct sunlight can heat the case faster than the processor itself.

Software techniques include cleaning up the boot. Go to settings and turn off unnecessary applications that run in the background. Often the cause of heating is "curved" app updates or bugs in the firmware itself. Check for system updates in Settings → About the phone. Sometimes the release of a new version of MIUI fixes problems with optimizing power consumption.

In rare cases, the problem can be hardware: the thermal paste between the processor and the radiator (relevant to older models) has dried up, or the battery has ballooned. SIM-This is a serious reason to contact the service center.
