How to find out the temperature of the processor on the Xiaomi phone: all the ways

Controlling the processor temperature on Xiaomi smartphones is a critical task, especially if you notice that the device has become slower to run, discharge quickly or turn off spontaneously. Overheating can indicate hardware problems, background processes or even malware. In this article, we will analyze all available methods for checking the temperature of the CPU, including hidden MIUI functions, engineering menus and third-party utilities.

It is important to understand that the normal temperature of the processor depends on the model of the smartphone and the load. For example, the Snapdragon 8 Gen 2 in the Xiaomi 13 Ultra under load can heat up to 60-70 ° C, while the budget Redmi 10A with the Helio G25 will begin trottling at 50 ° C. We will also tell you how to distinguish normal heating from critical overheating and what to do about it.

Why it is important to monitor the temperature of the processor

The processor (CPU) is the hottest component of a smartphone, and overheating leads to:

• 🔋 Accelerated wear of the battery - at a temperature higher 45°Lithium-ion batteries are degraded into 2-3 faster.
• ⚡ Trottling – forced reduction of the processor frequency, which is why games and applications begin to “lay down".
• 💥 Emergency shutdown – if the temperature exceeds 80-90°C, the smartphone will turn off to avoid damage.
• 🛠️ Breakdown of the motherboard – prolonged overheating can lead to chip detachment or damage to soldered contacts.

Especially vulnerable are Xiaomi flagship models with powerful chips (Snapdragon 8+ Gen 1, Dimensity 9000+), which under intense load (games, video rendering) can be heated to 70-85 ° C. At the same time, budget devices (Redmi Note 12, POCO M5) rarely exceed 55 ° C, but their cooling system is less efficient.

⚠️ Note: If the processor temperature exceeds 65°C in downtime (without running applications), this may indicate a thermal paste malfunction, radiator damage, or virus software mining cryptocurrency in the background.

Method 1: Built-in utility ##4636## (Engineer Mode)

The fastest way to check the temperature is to use a hidden engineering menu, which is available on all Xiaomi smartphones without installing additional apps:

1. Open the Phone app.
2. Enter the combination: ##4636### (some models may require ##6484###).
3. In the menu that appears, select Battery Information.
4. Scroll down to the Temperature unit – here you will find the battery and processor temperature (sometimes a combined metric).

On newer versions of MIUI 14+, this method may not work – Xiaomi has restricted access to the engineering menu.

💡

If the ##4636## combination doesn’t work, try typing it in the Contacts app instead of the standard dialer.

Method 2: CPU Monitor application (without root)

CPU Monitor is one of the few apps that displays the temperature of the processor on Xiaomi without having to obtain root rights. It reads sensor data through the standard Android APIs:

• 📥 Download. CPU Monitor from Google Play.
• 🔍 Launch the application and provide access to overlays (to display the widget).
• 📊 Go to the Temperature tab – here you will see data from all sensors, including: CPU, GPU battery.
• 📈 For a detailed analysis, click on the graph – you can see the history of temperature changes over the past few years. 5-30 minute.

The advantage of the CPU Monitor is the support of most Xiaomi models, including the Redmi Note 12 Pro+, POCO F5 and Xiaomi 13T. However, on some devices with MIUI 14, the application can only show the temperature of the battery.

Method 3: AIDA64 – Professional Analysis

AIDA64 is a powerful iron diagnostic tool that not only shows temperature, but also detailed information about the processor, memory and other components.

1. Install AIDA64.
2. Open the app and go to Sensors.
3. Scroll down to the Temperature block – here will be data for each CPU core (CPU Core 1, CPU Core 2, etc.).
4. To save the log, click on the floppy disk icon in the upper right corner.

AIDA64 supports even older Xiaomi models (e.g. Redmi 4X or Mi A1), but new flagships (Xiaomi 14, Mix Fold 3) may require additional permissions. If the temperature does not show, check the sensor access settings in Settings → Applications → Special Access.

Method 4: DevCheck – AIDA64 alternative

DevCheck is another popular hardware monitoring app that separates the processor temperature into a separate section and supports widgets for quick access:

• 📲 Install DevCheck.
• 🔧 Open the Hardware tab.
• 🌡️ Find the Thermals unit – here will be data on all sensors, including CPU, GPU battery.
• 📊 For a detailed schedule, click on any indicator.

DevCheck features support for MIUI 14 and new chips (Snapdragon 8 Gen 2, Dimensity 9200+).The app also shows the clock speed of the processor, which helps to identify trottling.

⚠️ Note: Some Xiaomi models (e.g. Redmi) K60) DevCheck can only show the temperature of the battery. AIDA64 or CPU Monitor.

Method 5: ADB-Teams (for advanced users)

If you don't want to install third-party apps, you can find out the temperature of the processor through ADB (Android Debug Bridge), which requires connecting the smartphone to the computer:

1. Enable USB Debugging in Settings → About Phone → MIUI Version (click 7 times, then go back to Settings → Additional → For Developers).
2. Connect your phone to your PC and confirm access to debugging.
3. Open the command line (cmd) and enter: adb shell cat /sys/class/thermal/thermal_zone*/temp
4. You will get a list of temperatures in milligrades Celsius (divide the value by 1000).

Example of output for Xiaomi 12T:

42000  # 42°C (CPU)


38000  # 38°C (Battery)




51000  # 51°C (GPU)

On models with MIUI 14 and newer, the path to sensors may be different. If the command doesn't work, try:

adb shell dumpsys thermal

This team will produce a full report on the thermal sensors, including the threshold values for trottling.

What to do if the processor overheats

If the temperature of the processor is constantly above normal, follow this algorithm:

1. Close the background applications – use Settings → Applications → Launched to force the stop of unnecessary processes.
2. Remove the case - dense silicone or leather covers worsen heat transfer.
3. Clean the connectors – dust and dirt in charging/dynamic ports can block ventilation.
4. Update the software – newer versions of MIUI often optimize power management.
5. Reset settings – if overheating started after the update, reset via Settings → Restore and Reset.
6. Check for viruses – use Malwarebytes or built-in Security from Xiaomi.

If the problem persists, it may indicate:

• 🔧 Thermopaste drying – requires disassembly and replacement (relevant for older devices) 2-3 years).
• 🔋 Battery malfunction – a bloated battery presses on the motherboard, worsening cooling.
• 🛠️ Radiator damage – on Xiaomi flagships (for example, Black Shark) the heat pipe can depart.

💡

If the temperature of the processor exceeds 70°C in idle mode, immediately stop using the device and contact the service center. Prolonged overheating can lead to irreversible damage to the chip.
