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:
- ๐ฅ Trottling โ forced productivity reduction to 30-50% heat-up 85ยฐC.
- ๐ Battery degradation โ Lithium-ion batteries lose up to 20% of capacity when continuously operating above 40ยฐC.
- ๐ฅ Emergency shutdown โ some models (such as Black Shark 5) turn off at 100ยฐC to avoid fire.
- ๐ ๏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.
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:
- Open the Phone app.
- Enter the combination: ##4636### (some models may require #4636633###).
- In the window that appears, select the Battery Information tab.
- 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.
- ๐ฑ Standby (screen off).
- ๐ฎ While playing (e.g. Genshin Impact or Call of Duty Mobile).
- ๐ When charging (especially with Quick Charge 4 support)+ or HyperCharge).
๐ก
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:
| Annex | precision | Demands a Root. | Additional functions |
|---|---|---|---|
| CPU Monitor | โญโญโญโญโญ | โ No. | Load schedules, overheating notifications |
| AIDA64 | โญโญโญโญ | โ No. | Performance tests, iron data |
| Cool Tool | โญโญโญ | โ Yes (for extended data) | Cooling by reducing the frequency of the CPU |
Instructions for using CPU Monitor (recommended for beginners):
- Download the app from Google Play.
- Open it and provide access to Overlays (to display temperature over other windows).
- Go to the Temperature tab โ here you will see data from all sensors, including the CPU, GPU and Battery.
- Click on the chart to see the history of changes over the last 5/15/60 minutes.
Make sure background apps are closed | Turn off sync and geolocation | Charge your phone at least 50% | Check the air vents for dust-->
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:
- 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.
- Connect the phone to the PC and confirm the debugging permission.
- Open the command line (Windows) or terminal (macOS/Linux) and type:
adb shell
cat /sys/class/thermal/thermal_zone*/tempYou'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?
โ ๏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:
| Chipset | Norm (ยฐC) | Warning (ยฐC) | Critical (ยฐC) | Xiaomi models |
|---|---|---|---|---|
| Snapdragon 8 Gen 2 | 30โ55 | 55โ75 | 75+ | Xiaomi 13 Pro, POCO F5 Pro |
| Dimensity 9000+ | 32โ60 | 60โ80 | 80+ | Redmi K60 Pro, Xiaomi 12T Pro |
| Snapdragon 778G+ | 28โ50 | 50โ65 | 65+ | POCO X5 Pro, Redmi Note 12 Pro |
| Snapdragon 480+ | 25โ45 | 45โ60 | 60+ | Redmi 10C, POCO M4 5G |
It is important to consider the context of the load:
- ๐ Calls/social media: up to 45ยฐC - normal.
- ๐ฎ Games: 60-70ยฐC โ acceptable for flagships, but should not last longer than 30 minutes.
- ๐ Charging: up to 50ยฐC - optimal; above 55ยฐC = risk to the battery.
- โ๏ธ Heat/direct sunlight: even 40ยฐC in standby mode - cause for concern.
๐ก
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).
โ ๏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 35โ40 after loading.ยฐC in 2-3 minutes.
What to do if the processor overheats
If you have a temperature above normal, follow the algorithm:
- Eliminate external factors: ๐ก๏ธ Move your phone to a cool place (not in the refrigerator!). ๐ Turn off charging if the temperature rises while connecting to the network. ๐งน Clean the Type-C connector and vents (on active-cooled models) of dust.
- Reduce the load: ๐ฎ Close games and heavy apps (such as Lightroom or Premiere Rush). ๐ Reboot the device โ it will reset the background processes. ๐ถ Turn it off. 5G/4G, If the signal is weak (constant search for the network heats the modem).
- Check the program reasons: ๐ ๏ธ Update. MIUI Up to the latest version (new firmware optimized energy consumption). ๐ฆ Check your phone for viruses (some mining bots are loading) CPU 100%). ๐ง Reset the settings to factory if overheating appeared after the update.
- Diagnostics of equipment: ๐ Check the battery for bloating (you can put the phone on a flat surface and spin - if it sways, the battery is deformed). ๐งช 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:
- Open Settings โ Special features โ Game turbo mode.
- 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.
- ๐ Charging: Use Xiaomiโs 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).
- ๐ฎ 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):
- ๐ Clean the fan with compressed air once every 3 months.
- ๐ง Check the turbine through the SharkSpace app (noise should be heard when loading).
- ๐ซ Do not block the vents with your fingers while playing.
