How to find out the temperature of the processor on Xiaomi: all methods and values

Overheating is one of the most common problems for Xiaomi owners, especially on flagship models like the Redmi Note 12 Pro+ or POCO F5. High temperatures not only reduce performance, but can lead to trottling (automatically lowering the CPU frequency) or even battery damage. However, most users do not know how to properly measure the temperature of the chipset and distinguish normal values from critical values.

In this article, we will look at all the available methods for checking the temperature of the processor on Xiaomi devices, from built-in MIUI tools to third-party utilities and ADB commands. You will also learn what indicators are considered safe for different models, what to do when overheating and how to prevent it in the future.

Why it is important to control the temperature of the processor

Qualcomm Snapdragon and MediaTek Dimensity processors installed in Xiaomi smartphones are designed to work in a wide temperature range, but exceeding the norm leads to serious consequences:

  • ๐Ÿ”ฅ Trottling โ€“ forced productivity reduction to 30-50% heat-up 85ยฐC.
  • ๐Ÿ“‰ Battery degradation โ€“ Lithium-ion batteries lose up to 20% of capacity when continuously operating above 40ยฐC.
  • ๐Ÿ’ฅ Emergency shutdown โ€“ some models (such as Black Shark 5) turn off at 100ยฐC to avoid fire.
  • ๐Ÿ› ๏ธ Damage to soldered contacts โ€“ prolonged overheating can cause microcracks on the motherboard.

Especially vulnerable are active cooling devices (such as the POCO F4 GT with a fan) โ€“ their system is designed for intense loads, but when clogging with dust, the efficiency drops by 2-3 times. Regular temperature checks help to detect the problem in time and avoid expensive repairs.

๐Ÿ“Š How often do you check the temperature of your Xiaomi processor?
Never.
Only when the phone is warm
Regularly, 1 time a month
Constantly monitored.

Method 1: Hidden Menu of Engineering Settings (#4636##)

The fastest and most reliable method is to use a hidden service menu available on all Xiaomi smartphones, regardless of the MIUI version.

To open the menu:

  1. Open the Phone app.
  2. Enter the combination: ##4636### (some models may require #4636633###).
  3. In the window that appears, select the Battery Information tab.
  4. Scroll down to the Temperature block - here data from the processor, battery and body sensors are displayed.

Note that the values are updated in real time, but they can be 1-2 seconds behind.

  • ๐Ÿ“ฑ Standby (screen off).
  • ๐ŸŽฎ While playing (e.g. Genshin Impact or Call of Duty Mobile).
  • ๐Ÿ”‹ When charging (especially with Quick Charge 4 support)+ or HyperCharge).

If ##4636### doesn't work, try entering it through Contacts โ†’ Add New Contact โ†’ Phone Number Field. On some MIUI firmware, this works.

Method 2: Temperature monitoring applications

If the hidden menu is not available (for example, on custom firmware), use third-party utilities. 10 popular applications and selected the top-3 with maximum accuracy of readings for Xiaomi:

Precision Warning: Some applications (e.g., CPU-Z) only show the temperature of the battery, passing it off as the temperature of the processor. Always check the data with 2-3 sources!

Method 3: ADB commands for advanced users

If you want the most accurate sensor data (for example, to diagnose malfunctions), use ADB (Android Debug Bridge), which requires connecting your smartphone to a PC, but gives you access to raw sensor values that are not filtered by MIUI.

Step-by-step:

  1. Enable USB Debugging in the Developer Settings โ†’ About Phone โ†’ MIUI Version โ€“ Press 7 times, then go back to Additional Settings โ†’ For Developers.
  2. Connect the phone to the PC and confirm the debugging permission.
  3. Open the command line (Windows) or terminal (macOS/Linux) and type:
adb shell


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

You'll get a list of values in milligrades Celsius (divided by 1000 to translate to ยฐC). For example, line 42800 means 42.8ยฐC.

  • thermal_zone0 โ€” processor (CPU).
  • thermal_zone1 โ€” graphical (GPU).
  • thermal_zone2 โ€” battery.
  • thermal_zone3+ โ€” Additional sensors (camera, module) 5G etc.).
How to find a specific processor sensor?
To determine exactly which zone corresponds to CPU, Enter the command: Adb shell cat /sys/class/thermal/thermal_zone*/type This will display a list of sensor types (e.g., "cpu-thermal", "battery", "gpu").

โš ๏ธ Note: on some Xiaomi models (e.g. Mi) 11 Ultra) access /sys/class/thermal/ blocked even though ADB. This will only help to obtain root rights.

Temperature standards for Xiaomi processors

The temperature tolerances depend on the chipset model and operating conditions, and below is a table of normal and critical indicators for popular processors in Xiaomi smartphones:

ChipsetNorm (ยฐC)Warning (ยฐC)Critical (ยฐC)Xiaomi models
Snapdragon 8 Gen 230โ€“5555โ€“7575+Xiaomi 13 Pro, POCO F5 Pro
Dimensity 9000+32โ€“6060โ€“8080+Redmi K60 Pro, Xiaomi 12T Pro
Snapdragon 778G+28โ€“5050โ€“6565+POCO X5 Pro, Redmi Note 12 Pro
Snapdragon 480+25โ€“4545โ€“6060+Redmi 10C, POCO M4 5G

It is important to consider the context of the load:

  • ๐Ÿ“ž Calls/social media: up to 45ยฐC - normal.
  • ๐ŸŽฎ Games: 60-70ยฐC โ€“ acceptable for flagships, but should not last longer than 30 minutes.
  • ๐Ÿ”‹ Charging: up to 50ยฐC - optimal; above 55ยฐC = risk to the battery.
  • โ˜€๏ธ Heat/direct sunlight: even 40ยฐC in standby mode - cause for concern.

๐Ÿ’ก

If the temperature of the processor exceeds 80ยฐC in games or 60ยฐC when charging, this is a sign of a malfunction (thermopaste, fan or power supply).

โš ๏ธ Warning: On liquid-cooled devices (such as the Black Shark 5 Pro), the temperature can jump sharply โ€“ this is normal if it drops to 35โ€“40 after loading.ยฐC in 2-3 minutes.

What to do if the processor overheats

If you have a temperature above normal, follow the algorithm:

  1. Eliminate external factors: ๐ŸŒก๏ธ Move your phone to a cool place (not in the refrigerator!). ๐Ÿ”Œ Turn off charging if the temperature rises while connecting to the network. ๐Ÿงน Clean the Type-C connector and vents (on active-cooled models) of dust.
  2. Reduce the load: ๐ŸŽฎ Close games and heavy apps (such as Lightroom or Premiere Rush). ๐Ÿ”„ Reboot the device โ€“ it will reset the background processes. ๐Ÿ“ถ Turn it off. 5G/4G, If the signal is weak (constant search for the network heats the modem).
  3. Check the program reasons: ๐Ÿ› ๏ธ Update. MIUI Up to the latest version (new firmware optimized energy consumption). ๐Ÿฆ  Check your phone for viruses (some mining bots are loading) CPU 100%). ๐Ÿ”ง Reset the settings to factory if overheating appeared after the update.
  4. Diagnostics of equipment: ๐Ÿ”‹ Check the battery for bloating (you can put the phone on a flat surface and spin - if it sways, the battery is deformed). ๐Ÿงช If overheating persists - contact the service to check the thermal paste and cooling system.

On models with game mode (for example, POCO F-series), you can manually limit the performance:

  1. Open Settings โ†’ Special features โ†’ Game turbo mode.
  2. Select Performance Limits and set a limit of 70-80%.

How to Prevent Overheating in the Future

Preventing overheating will save battery life and extend the life of the processor.

  • ๐Ÿ”‹ Charging: Use Xiaomiโ€™s original power supplies (especially for models with HyperCharge) 120W). Do not play while charging โ€“ this increases the temperature by 20-30ยฐC. Remove the case when connecting to the network (especially silicone or thick).
  • ๐ŸŽฎ Games: Limit FPS in the graphics settings (for example, in PUBG Mobile set 30-40 fps. Use smartphone coolers (e.g. Black Shark FunCooler Pro). Close background apps before launching the game.
  • โ˜€๏ธ Operation: Do not leave your phone in direct sunlight (even when it is off).ยฐC and above 35ยฐC. Regularly update applications โ€“ new versions often optimize power consumption.

For active cooling devices (e.g. RedMagic 7S Pro or Black Shark 5 Pro):

  • ๐ŸŒ€ Clean the fan with compressed air once every 3 months.
  • ๐Ÿ”ง Check the turbine through the SharkSpace app (noise should be heard when loading).
  • ๐Ÿšซ Do not block the vents with your fingers while playing.

The optimum temperature for battery life is 10โ€“35ยฐC. Every 10ยฐC above 30ยฐC reduces battery life by 20%.

FAQ: Frequent questions about the temperature of the Xiaomi processor

โ“ Why does the processor temperature jump from 30ยฐC to 70ยฐC in a few seconds?
This is normal for modern chipsets (for example, Snapdragon 8 Gen 2), which use dynamic clock control. When you have a sharp load (open the game, render video), the CPU instantly accelerates, which causes a temperature jump. If after 1-2 minutes the value stabilizes, there is nothing to worry about. However, if the jumps occur in standby mode, check the phone for viruses or background processes (for example, mining bots).
โ“ Can I use a refrigerator to cool my phone?
โŒ Absolutely not! A sharp temperature difference (e.g. from 60)ยฐC to 5ยฐC) may cause: Condensation within the shell โ†’ Short circuit. Thermopaste detachment from the processor. Battery deformation. The best way to cool the phone is to put it on a metal surface (for example, an aluminum radiator) or use specialized coolers.
โ“ Why did the temperature change after the replacement of the thermopaste?
The reasons may be as follows: ๐Ÿ”ง The thermopaste is applied unevenly (should be a thin layer without bubbles). ๐Ÿ”‹ The problem is the battery - the bloated battery presses on the motherboard, worsening the heat sink. ๐Ÿงช Faulty temperature sensor (check readings through the ADB). ๐ŸŒ€ On models with a fan (Black Shark, POCO F-series) may be clogged turbine. If the replacement of the thermal paste did not help, contact the service for a diagnostic cooling system.
โ“ How the CPU Temperature Affects Charging?
Modern Xiaomi smartphones automatically reduce charging current when heated: 30-40ยฐC: Charging is at maximum speed (e.g, 120W on Xiaomi 12 Pro. 40-50ยฐC: Current is reduced to 50-70% of maximum. 50ยฐC+: charging is suspended until cooling. โš ๏ธ If the phone is hotter than 50ยฐC without load (just lying on the table), this is a sign of a malfunction of the power supply or cable.
โ“ What covers are best to use so that the phone does not warm up?
Choose covers made of thermal conductive materials: ๐Ÿฅ‡ Aluminum/metal: the best heat sink, but heavy and expensive (e.g. Spigen Thin Fit cases). ๐Ÿฅˆ Carbon fiber: light and strong, good heat dissipates. ๐Ÿฅ‰ Thin silicone (0.3โ€“0.5 mm): minimal effect on heat transfer. ๐Ÿšซ Avoid: Thick covers with soft coating (for example, TPU 1.5+ Magnet covers (can affect sensors) models with bubbles or ribbed surfaces, which degrade heat transfer.
