How to check the temperature of the processor on the phone Xiaomi

Modern Xiaomi smartphones have powerful hardware that can heat up significantly when under heavy loads. Understanding the real-world performance of CPU and GPU thermal sensors is critical to diagnosing performance issues. The standard MIUI interface often hides this data by providing only general information about battery power.

Device owners often notice that the phone starts to slow down or discharge quickly just when the case gets hot. This is a direct signal that the thermoregulation system is at its limit. In this article, we will examine proven methods for obtaining accurate numbers, from simple applications to engineering commands.

Overheating is not to be ignored, as constant high-temperature operation accelerates battery degradation. Accurate diagnosis helps to understand whether heating is the norm for running a game or the result of a system failure. Let's look at what tools are available to the user to monitor the state of the hardware.

MIUI staff capabilities and hidden metrics

The MIUI operating shell and its global version of HyperOS have built-in overheating protection mechanisms, but they don't always display specific degrees on the screen.The system automatically reduces the CPU frequency if sensors capture critical values. However, the user can access advanced statistics through a developer menu or special codes.

Often, the built-in task manager only shows the total load, without detailing the heat output of individual cores. For a basic assessment, you can use the "Safety" section, which displays the optimization status, and if the system thinks that the phone is overheating, it will force the background processes to close.

Consider that different models behave differently, like the flagship Xiaomi 13 or Xiaomi 14 have better cooling systems than the budget Redmi series. So their heating thresholds will differ. It is important not to compare the readings of devices of different classes directly.

Use of third-party monitoring applications

The most affordable way to know the temperature is to install specialized software from Google Play, which reads data from system sensors through standard Android APIs, which are convenient for quick checks, but can show averaged values.

One of the leaders in this niche is the CPU-Z application, which provides detailed information not only about the temperature, but also about the current clock speed of each core, which allows you to understand which core is warming the most at the moment.

• 🌡️ CPU-Z — A classic tool that shows the temperature of each core and the total load in real time.
• 📊 AIDA64 — professional combine that displays data on all sensors of the smartphone, including voltage and frequencies.
• 🔋 AccuBattery – Focuses on battery health, but also displays the current battery temperature, which indirectly indicates the heating of the case.

On newer versions of Android 12/13/14, access to some sensors may be limited, in which case the readings may be irrelevant or not available.

💡

To get the most accurate data, run monitoring, close all background apps and leave your phone lying on a hard surface for 5-10 minutes.

Checking through the engineering menu and ADB-team

For advanced users who need raw data directly from the controller, there is a method of using ADB (Android Debug Bridge) debugging, which requires a connection to a computer, but gives the most honest picture without software distortion.

First, activate the developer mode. To do this, go to Settings → About Phone and quickly click on the MIUI version seven times. After that, a new section will appear in the menu “Advanced Settings” or “Additional”, where you need to turn on “Debugging by USB”.

Connecting your smartphone to a PC with ADB installed, you can command to display a list of all temperature sensors, which will allow you to see the readings of each sensor separately.

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

The list of numbers that you get is a temperature in tenths of a degree Celsius. 45000 signifier 45.0°C. To understand which sensor is which, you can use the command adb shell cat /sys/class/thermal/thermal_zone*/type, which will display names (cpu-thermal, battery, skin, etc.).

Indicators analysis: norms and critical values

Once you get the numbers, you often don't know what to do with them, different components of a smartphone have different operating ranges, and the processor can operate at higher temperatures than a battery that already considers heating above 45°C stressful.

The critical threshold for most Snapdragon and MediaTek mobile processors is 80-85°C. When you reach these values, you start trottling, which is a sharp decrease in performance to prevent chip damage, and if you see these numbers in plain, it's a sign of malfunction.

Note that the body temperature (Skin) is always below the internal temperature of the chips. If the phone in the hand seems to burn (more than 45 ° C), the inside of the processor may already be at its limit. Persistent heating above 50 ° C in standby mode indicates a software failure or a “broken” process in the background.

💡

Short-term heating to 60-70°C during fast charging or heavy gaming is a standard situation for modern flagships Xiaomi.

Factors affecting Xiaomi’s heating

Understanding the causes of heat helps prevent it. Xiaomi’s ecosystem has its own characteristics that can cause a rise in temperature even without active play, often culprits are unoptimized applications or system features.

One of the common reasons is the background activity of Google services or MIUI itself after the update, the system performs file indexing and database optimization, which loads the processor, and also affects the brightness of the screen and the use of communication modules.

• 📶 The weak signal of the network when the phone loses 4G/5G, It increases the power of the transmitter, which causes strong heating of the lower part of the body.
• 🔆 High brightness – the display at maximum on a sunny day is one of the main sources of heat.
• 📱 Heavy case – tight silicone or leather cases disrupt passive cooling, creating a “thermos” effect».

Also worth mentioning is the memory expansion feature, often found in newer models: Using part of the internal memory as a virtual RAM can increase the heat output of the memory controller, since the speed of work with flash memory is lower than that of pure RAM.

Temperature reduction methods and optimization

If the monitoring shows that it is over-regulated, you need to take action. There are several effective ways to lower the temperature without losing functionality. The first step is to audit the installed applications and background processes.

MIUI has Game Turbo, which not only improves performance, but also allows you to customize cooling profiles. Disabling unnecessary visuals and animations also reduces the load on the GPU.

⚠️ Warning: Never put a heated smartphone in the fridge or freezer! a sharp temperature drop will cause condensation inside the case, which will lead to short circuit and corrosion of the board.

To radically reduce the temperature, you can temporarily turn off mobile data and use only Wi-Fi, because the cell module consumes a lot of energy. AMOLED-screens where black pixels are not illuminated.
