Xiaomi smartphones are some of the most popular devices on the market, but their performance is directly dependent on thermal mode. Overheating can lead to sudden shutdowns, slowdowns or even battery damage. Knowing how to check the temperature on Xiaomi, you can prevent problems in time and prolong the life of your gadget.
In this article, we will discuss all available methods - from built-in tools. MIUI You will learn how to monitor the temperature of the processor, battery and even individual components, and what to do if the performance is out of the norm. Instructions are suitable for all models, from the budget Redmi to the flagship Xiaomi 14 and the other. POCO F6.
MIUI built-in tools: where to watch the temperature without apps
The manufacturer has provided several ways to check the temperature directly in the firmware MIUI, these methods do not require the installation of additional software and work on most devices, starting with MIUI 12.
The easiest way is through the battery menu. Go to Settings → Battery and scroll to the consumption chart. The top right corner can display the current battery temperature (not always available on all models). If this item is not available, try an alternative method:
- 🔍 Using the engineering menu: enter the phone application combination ##4636##. In the window that opens, select Battery Information - there will be a Temperature value (in degrees Celsius multiplied by 10 degrees Celsius).
- 📊 Under System Status: Go to Settings → The phone. → Version. MIUI And you can tap the kernel several times, and you can open a hidden menu with detailed information, including the temperature of the processor.
- ⚡ During charging: some models (Xiaomi) 13T, Redmi Note 12 Pro+) The battery temperature is indicated in the charging notification if it exceeds 40.°C.
Note that embedded tools often only show the temperature of the battery, whereas it is important to know the status of the processor and other chips to diagnose overheating. If you need more detailed data, move on to the following methods.
2 Hidden codes for diagnosis: engineering menu and test modes
For advanced users, Xiaomi has provided hidden service codes that open up technical information, which work on most devices, but may vary depending on the model and firmware version.
The most useful combinations:
| Code. | Description | Application |
|---|---|---|
| ##4636## | Battery information, networking and usage statistics | Battery temperature, signal level, Wi-Fi data |
| ##225## | Sensor calibration | Checking the operation of thermosensors (requires rebooting) |
| ##6484## | Hardware test | Processor temperature, RAM, flash memory |
| ##64663## | Information on modules | Temperature and humidity sensor data |
⚠️ Note: Not all codes work on new models (Xiaomi 14 Ultra, POCO F6 Pro) due to manufacturer restrictions. If nothing happens after entering the combination, then the function is disabled in your firmware. ADB third-party.
For devices with Qualcomm Snapdragon processors (most Xiaomi/Redmi/POCO) there is another way:
- Install the Shortcut Maker app from Google Play.
- Select the Secret Code option and type ##6484##.
- Create a shortcut on the home screen – it will open the engineering menu with temperature data.

3. Temperature monitoring apps: TOP-5 utility for Xiaomi
If the built-in tools don't give you the full picture, third-party apps come to the rescue, not only showing the temperature in real time, but also keeping statistics, notifying you of overheating and analyzing the load on the processor.
The best programs for Xiaomi:
- 📱 CPU Monitor - displays the temperature CPU, GPU It supports widgets for the home screen.
- 🔥 AIDA64 — It's a professional system analyzer with detailed information about each sensor, showing the temperature even for little-known chips.
- 🛠️ DevCheck is a lightweight application with a user-friendly interface, shows the temperature in the Hardware section.
- 📊 Cool Tool – specializes in overheating control, offers optimization to reduce temperature.
- 🔋 AccuBattery – Focuses on battery status, but also monitors battery temperature during charging/discharge.
💡 Advice: If you are using POCO or Black Shark, note Game Turbo – the built-in app for gamers often shows the temperature of the processor during games.
Before installing any of these apps, check reviews on 4PDA or XDA Developers – some utilities may conflict with MIUI or require root rights.
Clear the cache in Settings → Storage
Check the MIUI version (some apps don’t work on beta firmware)

4. ADB-How to find the temperature through the computer
For those who prefer to work with Android Debug Bridge (ADB), there is a way to get temperature data directly from the PC, which is suitable for diagnosing “hung” devices or when the screen does not respond to touch.
Instructions:
- Install ADB Tools on your computer.
- Turn on USB Debugging on your smartphone: Settings → About Phone → MIUI version (tap 7 times on this item, then go back to Settings → Additional → For Developers).
- Connect the device to the PC and enter in the command line: adb shell dumpsys battery In the answer, find the temperature line - the value is indicated in tenths of a degree (for example, 345 = 34.5 ° C).
To obtain the temperature of the processor, use the command:
adb shell cat /sys/class/thermal/thermal_zone*/tempIt will list all thermal zones with current values (in milligrades Celsius).
⚠️ Note: On some devices (Xiaomi) 12S Ultra, Redmi K60 Pro) access to thermal sensors may be restricted. If the team returns a Permission denied error, root rights will be required.
@echo off
adb shell dumpsys battery | find "temperature"
adb shell cat /sys/class/thermal/thermal_zone*/temp
pause5. Temperature standards for Xiaomi: when to worry
Not all high temperatures are a cause for panic, Xiaomi devices have their own operating ranges, which depend on the model, processor and load.
| Component | Norm (°C) | Critical threshold (°C) | Cause of overheating |
|---|---|---|---|
| Battery | 25–40 | 45+ | Fast charging, background processes |
| The processor (Snapdragon) | 30–65 | 80+ | Games, rendering, bad thermal paste |
| Processor (Mediatek) | 35–70 | 85+ | Multitasking, unoptimized software |
| Screen (AMOLED) | 45 | 50+ | Brightness 100%, sunlight |
| Charging controller | 50 | 60+ | Use of non-original RMS |
Critical information: On devices with a Snapdragon 8 Gen 2 processor (Xiaomi 13, POCO F5 Pro), normal temperature under load can reach 75 ° C - this is not a defect, but a feature of the architecture. However, if the smartphone turns off at 60 ° C, this is a sign of a sensor or thermal paste malfunction.
What to do if the temperature is higher than normal:
- 🔌 Charging: Use original RAM and cable, avoid wireless charging in the heat.
- 🎮 Games: limit FPS in the graphics settings or use the gamepad with cooling.
- ☀️ Exploitation: Do not leave your phone in direct sunlight (even when it is off!).
- 🧹 Cleaning: regularly remove dust from the charging connector and speakers - it worsens the heat sink.
💡
If the battery temperature exceeds 45°C during simple charging (no games or heavy tasks), this is a sign of battery degradation.
Hardware methods: how to measure temperature without software
If the smartphone is not turned on or the screen is not working, you can estimate the temperature by touch or using external tools, which can be useful for diagnosing bricks after a failed update or physical damage.
How to check:
- tactile: 🔋 Battery: gently touch the back cover in the center. Normally warm, but not hot. 📱 Processor: The top of the device (near the camera) should not burn your fingers. 🔌 Charging controller: the lower edge near USB-Port – if it’s hot, the problem is charging.

Thermal imager
⚠️ Note: If the case Xiaomi is heated to such an extent that it is impossible to hold in your hands (above 60).°C), immediately:
- Turn off the charging.
- Turn off the device (press the power button for 10+ seconds).
- Place the phone on a non-combustible surface (such as a ceramic plate).
- Do not cool it in the refrigerator or under a stream of cold water – it can cause condensation inside!
- it means that a diagnosis is required (cleaning from dust, replacing thermopaste).
