Why it is important to monitor the temperature of the processor in Xiaomi smartphones
Overheating is one of the most common problems with Xiaomi smartphones, especially in the budget Redmi series and the newest. POCO. Processor (CPU) It can be heated to a critical 90-105.ยฐC under intense loads: games, shooting video in 4K The consequences of ignoring high temperature range from automatic trottling (decreased performance) to irreversible battery damage or even battery bloating.
Xiaomi owners face overheating more often than others due to aggressive optimization MIUI and use Qualcomm Snapdragon or MediaTek Helio processors with high TDP. For example, the Redmi Note 10 Pro and POCO X3 Pros are known for cooling problems due to their compact body and lack of graphite heat dissipator in some revisions. But how do you know if the phone is actually overheating? The first signs are spontaneous reboots, slowing down the interface or warning the system โTemperature is too highยป.
In this article, weโll break down 6 working ways to check the CPU temperature on any Xiaomi smartphone, including hidden engineering menus, third-party apps, and built-in tools. MIUI. You will learn which values are considered normal and which require immediate action.
Normal and critical temperature values for Xiaomi
Chipset manufacturers set different maximum operating temperature (TjMax) thresholds for their processors. For most Xiaomi smartphones, the following ranges are relevant:
| Status. | CPU temperature (ยฐC) | Causes | Action |
|---|---|---|---|
| Norma. | 25โ40 | Simple, web surfing, social networks | No action is required. |
| Elevated | 40โ60 | Games, video calls, charging | Monitor the dynamics, provide ventilation |
| Critical | 60โ80 | Long-term loads, background processes | Close the applications, remove the case |
| Dangerous. | 80โ100 | Battery malfunction, thermal paste damage | Turn off the device immediately, contact the service |
| Emergency. | 100+ | Short circuit, failure of the power controller | Don't use the device! |
It is important to note that MediaTek (e.g. Helio) G95 Redmi Note 11 Pros are more likely to heat up the Snapdragon because of the less efficient architecture, POCO F3 Snapdragon 870 will be colder than Redmi Note 10S Helio G95 10-15ยฐC. The temperature is also affected by the version MIUI: In firmware based on Android 12-14 added mechanisms Dynamic RAM Expansion that increases the burden on CPU.
โ ๏ธ Note: If the processor temperature is greater than 85ยฐC for normal tasks (e.g. watching YouTube), this may indicate a faulty heat pad between the chipset and the case.

Frequent Causes of Xiaomi Overheating and How to Remove Them
Overheating is rarely "on its own" - usually due to hardware or software problems. TOP-7 causes of high processor temperature in Xiaomi smartphones and ways to eliminate them.
| Reason. | Symptoms | Decision |
|---|---|---|
| Background processes | The phone warms up in simple, the battery quickly goes down | Turn off auto-run of unnecessary apps in Settings โ Annexes โ Permits |
| Damaged battery. | Bloating, the phone turns off at 30-40% charge | Replace the battery at the service center (cost: 1,500โ3,000) โฝ) |
| Dust in the charging connector | The phone warms up when connected to the network | Clear the port. USB-C toothpick |
| Thermopaste malfunction | Overheating with minimal loads (for example, in the menu) | Disassembly and replacement of the thermal interface (only in the service!) |
| Viruses/mining | CPU It is 100% loaded for no apparent reason. | Check Malwarebytes phone or reset to factory settings |
Additional advice:
- ๐ Update. MIUI Up to the latest version โ in the new firmware optimized cooling algorithms.
- ๐ฎ For gamers: Use a smartphone cooler (e.g. Black Shark FunCooler Pro).
- โ๏ธ Avoid direct sunlight โ even a simple phone can heat up to 50ยฐC.
- ๐ฆ Remove the case when used intensively (especially silicone โ it worsens heat transfer).
๐ก
If the temperature of the processor is stable above 70ยฐC for normal tasks (e.g. WhatsApp), this is a sign of hardware malfunction. Donโt delay a visit to the service center โ prolonged overheating reduces battery life by 2-3 times.
