How to find out the temperature of the Xiaomi phone: hidden codes, applications and settings MIUI

Overheating is one of the most common problems faced by Xiaomi, Redmi, POCO and Black Shark. High temperatures not only reduce performance, but can damage the battery or internal components. However, it is not always clear when the device is really overheated and when it is simply warm due to intensive work. In this article, we will discuss all the available methods of temperature checking on Xiaomi phones, from built-in MIUI tools to third-party applications and engineering menus.

It's important to understand that the normal operating temperature of a smartphone ranges from 30ยฐC to 45ยฐC depending on the load. Exceeding 50ยฐC is already considered critical and requires intervention. But how do you know exactly how hot your Xiaomi is? Next, detailed instructions for different models and firmware versions.

MIUI Integrated Tools: Where to Watch Temperature Without Apps

Xiaomi has integrated several ways to monitor temperature into its MIUI shell, but they are not always obvious. The easiest method is to use a battery menu that displays the approximate battery temperature. However, this indicator is not always accurate and does not take into account the heating of the processor or other components.

To see the temperature of the battery:

  • ๐Ÿ“ฑ Open the Settings. โ†’ Battery.
  • ๐Ÿ”‹ At the top of the screen, find a power consumption chart โ€“ the current temperature can be displayed there (e.g. 38).ยฐC).
  • โ„น๏ธ In some models (for example, POCO F5 Redmi Note 12: The temperature is only shown when charging.

If your MIUI version doesnโ€™t have this item, try an alternative path:

  1. Launch the Security app (the shield icon).
  2. Go to the Optimization section โ†’ Temperature.
  3. The current heating status of the device (e.g., โ€œNormalโ€ or โ€œHighโ€) will be displayed here.

On Black Shark phones, the processor temperature is displayed in Shark Space game mode. Run it through the notification panel to see detailed CPU/GPU data.

2 Hidden engineering menus: how to find out the temperature through USSD-code

For advanced users, Xiaomi has provided hidden service menus where you can get detailed information about the condition of iron. USSD-Note that not all codes work on new models (e.g. Xiaomi 14 or Redmi). K70), But most devices on Qualcomm Snapdragon are relevant.

Basic codes for temperature check:

Code.DescriptionWorks on
##4636##Test menu, Battery information tab (battery temperature)Most Android models
##225##Checking the calibration of the battery (can show the temperature)Redmi 9/10, POCO X3
##6484##Hardware test (includes CPU temperature data)Devices on MediaTek
##64663##MTK Engineer Mode Menu (for MediaTek processors)Redmi Note 8/9, POCO M3

Once you enter the code, you will be taken to the engineering menu, for example, at ##4636###, select Battery information, which will have the Temperature string with the current value in degrees Celsius. On some firmware, this menu may be blocked, in which case you will need to unlock the bootloader.

3. Third-party apps: top-5 temperature monitoring

If the built-in MIUI tools don't provide enough data, you can use third-party apps that not only show the battery temperature, but also track the heating of the processor (CPU), graphics chip (GPU), and other components. Importantly, some utilities require root rights to fully access the sensors.

The best apps for Xiaomi:

  • ๐Ÿ“Š AIDA64 โ€” temperature CPU, GPU, Batteries and even individual processor cores, POCO and Black Shark.
  • ๐Ÿ”ฅ CPU Monitor โ€“ monitors heating in real time with notifications of critical values.
  • ๐Ÿ”‹ AccuBattery โ€“ specializes in battery status, but also displays its temperature during charging/discharge.
  • ๐ŸŽฎ Game Booster 5 (for gamers) โ€“ shows the temperature during games, optimizes cooling.
  • ๐Ÿ› ๏ธ DevCheck โ€“ a user-friendly interface with data on all sensors, including thermometers.

Example of AIDA64:

  1. Download the app from Google Play.
  2. Open the Sensors section.
  3. Find the Temperature strings, and there will be data on the battery (Battery), the processor (CPU), and other components.
Why can apps show different temperatures?
Third-party utilities read data from different sensors, for example, AIDA64 takes information directly from the power controller, and MIUI can use averages, a difference of 2-5 ยฐ C is normal.

Warning: Some applications (such as CPU-X) require permission to access ADB or root. Without them, they will only show basic information.

4.Temperature during games: How to control heating on POCO and Black Shark

POCO and Black Shark gaming smartphones often suffer from overheating due to powerful processors (Snapdragon 8 Gen 2/3) and heavy loads.

On Black Shark 5/6 and POCO F5 Pro:

  • ๐ŸŽฎ Start a game (such as Genshin Impact or Call of Duty Mobile).
  • ๐Ÿ”ง Swipe from top to bottom to open the notification bar and activate Game Mode (Game Turbo or Shark Space).
  • ๐ŸŒก๏ธ A floating window with temperature will appear on the screen. CPU/GPU and FPS. On Black Shark, you can display this data over the game.

If you donโ€™t have a game mode in your firmware, use the Game Bench app:

  1. Install the utility from the official store.
  2. Launch the game through Game Bench.
  3. After the session, check the report โ€“ there will be a graph of temperature and load on the processor.

Clear background processes before starting|Reduce the graphical settings in the game|Use a cooling cover or fan|Update the firmware to the latest version-->

Critical information: on the Black Shark 5 Pro and the new POCO F6, the CPU temperature can reach 70-80ยฐC in heavy games โ€” this is normal due to the liquid cooling system. However, if the phone turns off from overheating, it is a signal that the thermal paste or cooling system is malfunctioning.

5 Hardware methods: how to measure temperature without software

If the phone doesn't turn on or you don't trust the software, you can measure the temperature physically with an infrared thermometer, a technique that is suitable for diagnosing overheating of the processor or battery when the device is behaving unstablely (for example, suddenly shut down).

How to measure correctly:

  • ๐Ÿ” Point the thermometer to the back cover in the processor area (usually the top of the body).
  • ๐Ÿ”‹ To check the battery, remove the back panel (if possible without damage) and point the thermometer at the battery.
  • โš ๏ธ Normal values: 35-45ยฐC under load, 25-35ยฐC to simple. 50ยฐC - Diagnosis required.

You can also use the tactile method:

โš ๏ธ Warning: If the phone body burns your hand (especially in the camera or processor area), it is a sign of critical overheating. 30-60 Continued use may cause the battery to swell.

For accurate diagnosis, the service center uses a thermocouple โ€“ it measures the temperature directly on the chip. If your Xiaomi is constantly overheating for no apparent reason, it is better to contact specialists to check the thermal interface (thermopaste) between the processor and the radiator.

6. Frequent causes of overheating and how to eliminate them

High temperatures are always the result of a problem, and letโ€™s look at the main reasons and ways to solve them for Xiaomi phones:

Reason.How to checkDecision
Background processesOpen Settings โ†’ Applications โ†’ LaunchedClose unnecessary programs, disable auto-start
Poor coolingCheck the temperature in games or benchmarks (AnTuTu)Use a cooling cover or replace the heat paste
Faulty batteryCheck out the battery wear in AccuBatteryReplace the battery at the service center
Viruses or miningCheck the CPU consumption in Settings โ†’ BatteryScan your phone with an antivirus (Dr.Web, Kaspersky)
Outdated firmwareCheck the version of MIUI in Settings โ†’ About the phoneUpdate the software through Settings โ†’ System Update

If the phone warms even in simple, reset to factory settings:

  1. Create a backup copy of the data.
  2. Go to Settings โ†’ About the phone โ†’ Reset settings.
  3. Choose to erase all data and confirm the action.

๐Ÿ’ก

On Xiaomi phones with MediaTek processors (for example, Redmi 10A), overheating is often associated with unoptimized software. In this case, only custom recavator firmware (TWRP) and the installation of alternative firmware (for example, Xiaomi.EU) will help.

7.When overheating is a malfunction: signs and actions

Sometimes high temperatures signal hardware failure, and here are the key signs that it's time to bring your phone to service:

  • ๐Ÿ”ฅ Phone heats up to 60ยฐC+ without load (e.g. in standby mode).
  • ๐Ÿ”‹ The battery swelled (see above the raised back cover or screen glass).
  • โšก The device turns off when charging or refuses to turn on before cooling down.
  • ๐Ÿ“‰ Performance drops dramatically (lags, slowdowns) even in simple tasks.

What to do in such cases:

โš ๏ธ Warning: If the battery is swelling, you can't try to puncture it or bend it! This can cause fire.

The cost of repair in official Xiaomi services:

  • Battery replacement: 1,500 to 3,000 โ‚ฝ (model-wise).
  • Thermopaste/therm interface replacement: from 2,000 โ‚ฝ.
  • Diagnosis of the cooling system: free of charge (with subsequent repairs).

For phones older than 3 years (such as the Redmi Note 8 or POCO X2), repairs may not be cost-effective, so consider buying a new device โ€“ modern models (such as the Redmi Note 13 Pro+) have better cooling.
