Xiaomi, Redmi and POCO are all known for their performance, but powerful iron often causes heat. Many users notice that the device's body gets hot during games or charging, and begin to look for ways to check the real-world performance of the sensors. Temperature control is not just curiosity, but a necessity for extending the battery life and preventing trolling.
There are several proven methods to get accurate data about the current state of the system. In this article, we will discuss in detail how to find out the temperature of a Xiaomi phone using built-in features, hidden codes and third-party software so you can be sure of the health of your gadget.
Normal indicators and causes of overheating
Before you sound the alarm, it is important to understand what values are considered normal for mobile processors and batteries. 30 before 45 Celsius, when you start a heavy 3D-games or the procedure of fast charging heating to 50-55 The degree is also not critical, as modern chipsets Qualcomm and MediaTek are designed with such thermal regimes in mind.
However, there are situations where heating the case signals problems, and if you notice that the phone burns your hands even in plain, or the sensors are over 60 degrees, this may indicate a malfunction.
- 🔥 Running Resource-intensive Applications in the Background That You Are Not Using Right Now.
- 🔋 Battery degradation or problems with the power controller.
- 📶 Poor cellular signal that makes the communication module work at its limit.
Constant overheating can lead to a decrease in battery capacity and even to detachment of the plumes inside the device, so monitoring indicators is important for prevention.
⚠️ Warning: If the phone temperature is consistently above 65 degrees without active load, immediately stop using the device and let it cool off when it is off.
Use of Hidden Engineering Menu (CIT)
One of the most reliable ways to know the temperature of a Xiaomi phone is to access an engineering test menu known as CIT, which is built into the MIUI and HyperOS firmware by developers specifically for hardware diagnostics. You don't have to install any software, just type in a special code.
Open a standard caller and dial the combination ##6484##. Immediately after entering the last digit, the hardware check menu will open. In the test list, you need to find the item associated with the battery or temperature (usually called "Battery" or "Temperature sensor").
☑️ Check through CIT
This menu displays data from multiple sensors, and you're interested in Battery temperature and CPU temperature, and note that the data here is updated in real time, allowing you to track the dynamics of heating when you start applications.
💡
The values in the engineering menu are often more accurate than in third-party applications, as they are read directly from the motherboard controllers without software distortion.
Verification through system codes and USSD-team
In addition to the full engineering menu, there are simpler codes for quick diagnostics in the MIUI shell, which may vary depending on the Android version and firmware region. The basic code that runs on most models, including the Redmi Note and Xiaomi Mi series, is as follows:
##4636##Once you enter this command, the "Verification" menu opens. You should select "Battery Information" section. The window that opens will show "Temperature" where you can see the current value in tenths of a degree (e.g., 325 means 32.5°C). If the code doesn't work, try the alternative ##6485##, which displays a summary of the battery, including charge level and health status (Health).
It is important to understand that these codes may be blocked by the carrier or manufacturer in some global firmware versions, in which case the system will simply ignore the input or show a connection error message.
| Code. | Function | Availability of data |
|---|---|---|
| ##6484## | Full Testing (CIT) | Tall (all models) |
| ##4636## | Phone information | Medium (depending on version) |
| ##6485## | Battery summary | Low (often hidden) |
| *#06# | IMEI (not temperature) | 100% (always working) |
Third-party monitoring applications
If the built-in methods seem uncomfortable or the codes don't work, the Google Play Store's specialized apps come to the rescue, providing a more user-friendly interface, temperature charts and meter history, and the most popular and reliable tool is CPU-Z or AIDA64.
Once you install AIDA64, run the app and go to the "Thermal" section, and you'll see a list of all the sensors here, look for values marked "battery" or "cpu," and the advantage of these programs is that they can output a widget to the desktop that allows you to see the temperature without running the application.
Other useful utilities include Cooler Master or 3C Battery Monitor, which not only show degrees, but also help determine which process causes heating by analyzing the load on the cores of the processor.
Decoding of sensor indicators
In engineering menus and advanced apps, you can see a lot of strange sensor names. They can be difficult to understand, but the basic designations are worth knowing for every Xiaomi owner.
- 🌡️ Battery Temp: The real temperature of the battery chemical cell — 45-50°C.
- 💻 CPU Temp/SoC Temp: CPU temperature.Can briefly jump to 70-80°C under load.
- 🔌 Charger Temp: Charging controller temperature. Important parameter when using fast charging.
Often users confuse the temperature of the battery and the processor. The processor warms faster and cools faster, while the battery stores heat and cools longer. To assess the overall condition of the device, it is more important to monitor the Battery Temp.
Why are the readings in different applications different?
Temperature reduction methods and optimization
If the diagnostics show that you're overreacting, you need to take cooling action. Software optimization is the first step. Go to Settings → Battery and performance and select Balanced or Energy Saving mode, which will limit the CPU frequency and reduce heat generation.
Also worth checking is the list of running applications. MIUI has a built-in Memory Cleanup feature that closes the background processes, and it is worth turning off unused communication modules like GPS, Bluetooth and NFC, as their constant search for networks contributes to the overall heating.
⚠️ Warning: Never put a heated phone in the fridge or freezer! a sharp temperature drop will cause condensation inside the case, which will lead to a short circuit.
Physical methods are also effective: remove the protective case if it is dense and does not remove heat, and place the smartphone on a cold surface (such as tile or glass) in the shade.
💡
The combination of software optimization and cover removal reduces the temperature by an average of 3-5 degrees in 10 minutes.
