How to find out the temperature of the processor on Xiaomi: hidden codes, applications and ADB

CPU overheating is one of the most common problems with Xiaomi, Redmi and POCO smartphones, especially in hot weather or under intense loads. High temperatures not only reduce performance, but can also lead to automatic shutdown of the device or even battery damage, but most users do not know how to properly measure the temperature of the CPU to take action in time.

In this article, you’ll find 5 proven ways to check the CPU temperature on any Xiaomi device – from hidden engineering menus to specialized applications and ADB commands. We’ll also tell you which values are considered normal and which signal a problem, and what to do if a smartphone overheats for no apparent reason.

Important: The temperature sensors in Xiaomi smartphones can show different values for the processor (CPU), graphics accelerator (GPU), battery and even screen. This article will talk about the temperature of the central processing unit (SoC), as its overheating is most critical for the stability of the device.

1. Hidden Engineering Menu ##4636## is the fastest way

Most Xiaomi, Redmi and POCO smartphones have a hidden hardware testing menu where you can see the CPU temperature without installing additional apps, which works on devices with pure Android (such as Xiaomi 12T, POCO F4) and on MIUI firmware before version 14.

To open the menu:

1. Open the Phone app.
2. Enter the combination: ##4636### (some models may require #4636633###).
3. Select Battery Information (Battery Information).

In this section, you'll see the Temperature bar with the current battery temperature. However, the CPU temperature is not displayed here, so you can go to Usage statistics and find the CPU temperature box. Some firmware may not have this item, so use other methods in this article.

⚠️ Attention: On devices with MIUI 14+ And HyperOS can block the engineering menu. If nothing happens after you enter the code, try methods with apps or ADB.

2. Temperature monitoring applications: top-3 free-to-use

If the hidden menu is not available or does not show the temperature of the CPU, the best option is to install a specialized application. We tested dozens of programs and selected three of the most reliable and accurate solutions for Xiaomi.

1. CPU Monitor (Google Play)

• 📊 Shows the temperature of all processor cores in real time.
• 📈 Builds load and temperature graphs.
• ⚠️ Requires permission to access memory and processes (on Android 13)+ may not work without ADB).

2. AIDA64 (Google Play)

• 🔍 It displays temperature. CPU, GPU, battery-board.
• 🛠️ Provides complete information about the hardware (processor model, frequency, loading cores).
• 📱 It works on all versions. MIUI HyperOS.

3. DevCheck (Google Play)

• 🌡️ Shows the temperature in the Hardware section → Thermal.
• 📱 Minimalist interface, no advertising.
• ⚡ Updates data quickly (updates every second).

After installing any of these apps, open it and go to the temperature or iron section (Hardware, Thermal, CPU). Note that on some models (for example, Redmi Note 11 Pro+) applications can only show the battery temperature - this is a firmware restriction.

Make sure your smartphone is not on charge

Close all background applications

Turn off mobile data and Wi-Fi (if you check in downtime)

Check the temperature in different scenarios (games, video watching, easy to use)-->

3. Temperature check via ADB (for power users)

If you don’t want to install third-party apps or they don’t work on your Xiaomi model, you can use the Android debugging bridge (ADB), which requires connecting your smartphone to your computer, but gives you the most accurate data directly from the system.

You'll need:

• 🖥️ Computer with installed ADB Tools.
• 📱 Xiaomi smartphone with enabled debugging USB (Settings → The phone. → Version. MIUI (press 7 times) → Additionally. → For developers → Debugging by USB).
• 🔌 USB-cable (preferably original).

Instructions:

1. Connect your smartphone to your computer and allow debugging (a request will appear on the phone screen).
2. Open the Command Prompt (Windows) or Terminal (macOS/Linux) in the folder with ADB.
3. Enter a command to check the temperature CPU: adb shell cat /sys/class/thermal/thermal_zone*/temp The result will be in thousands of degrees Celsius (for example, 38429 = 38.4°C).
4. To see the temperature of all zones (CPU, GPU, battery), use: adb shell dumpsys thermal

On some models (such as the Xiaomi 13 Pro with the Snapdragon 8 Gen 2), the path to the sensors may be different. If the command doesn't work, try:

adb shell cat /sys/class/thermal/thermal_zone0/temp

⚠️ Note: On HyperOS devices (e.g. Xiaomi 14) some sensors are accessed via the ADB In this case, use the applications from section 2.

4. Normal and critical temperature values for Xiaomi

The processor temperature on Xiaomi smartphones depends on the chipset model, load and environment. Below is a table with acceptable and dangerous values for popular processors.

Snapdragon 8 Series processors (Gen 1/Gen 2) are prone to overheating due to the high density of transistors. If the temperature exceeds 70°C in games, this is normal, but if it stays above 75°C for more than 10 minutes, cooling is required.

Factors affecting temperature:

• 🌡️ Ambient temperature: at +30°C and higher smartphone will warm up more.
• 🔋 Charging: fast charging (e.g, 120W Redmi Note 12 Pro+) It can raise the temperature by 10-15°C.
• 🎮 Games and rendering: Genshin Impact or Call of Duty Mobile at maximum settings load CPU 80-100%.
• 📶 Weak network signal: if the smartphone is constantly looking for a network (for example, in the subway), this increases the load on the modem.

💡

If your smartphone is heating up for no apparent reason, check the background processes in Settings → Apps → Running. Often the culprits are optimizers, antiviruses or applications with permanent geolocation.

5.What to do if the processor overheats?

If the CPU temperature on your Xiaomi regularly exceeds 65-70°C without serious stress, this may indicate a thermal paste problem, clogged air vents (on active-cooled models), or a faulty battery.

Short-term measures (urgent cooling):

• ❄️ Remove the cover - it can block the heat sink.
• 🔌 Turn off charging and turn off mobile data/Wi-Fi.
• 🛑 Close all applications through recent tasks.
• 🌬️ Point a fan at your smartphone or place it in a cool place (but not in the fridge!).

Long-term solutions:

• 🔧 Update the firmware - in new versions MIUI/HyperOS Often optimize food management.
• 🔄 Reset the settings to factory (if overheating started after the update).
• 🛠️ Replace thermopaste (relevant for flagships over 2 years old).
• 🔋 Check the battery for bloating – this is one of the main reasons for overheating.

On active cooling models (such as Black Shark 5 Pro) check the fan:

1. Run a heavy game (e.g. PUBG Mobile at maximum settings).
2. Put your hand on the top of the body – you should feel the flow of air.
3. If the fan is not working, contact the service center.

⚠️ Note: If Xiaomi smartphone suddenly turns off at temperatures above 80°C, this is hardware damage protection. Don't turn it on right away -- let it cool for at least 15 to 20 minutes.

💡

Smartphones with Snapdragon 888/8 Gen 1 processors (e.g. Xiaomi 11T Pro, POCO F3 GT) are most vulnerable to overheating. If you own such a model, avoid long gaming sessions without cooling.

6. Xiaomi overheating myths: What's true and what's not?

There is a lot of conflicting information on the Internet about Xiaomi smartphones overheating, and let’s take a look at the most popular myths.

❌ Myth 1: If your smartphone is hot, it’s defective."

✅ Truth: Overheating at high loads (games, video shooting) 4K) — This is normal for most flagships, and marriage is considered heating in downtime (for example, for example, >50°C when browsing the web).

❌ Myth 2: “Cooled covers (with metal inserts) help lower the temperature."

✅ Truth: Most of these cases degrade heat sink, as the metal accumulates heat, not dissipates it. It is better to use cases made of perforated silicone or even remove the case during games.

❌ Myth 3: “Overheating kills the battery in 1-2 months."

✅ Truth: Regular heating to 60-70°C reduces battery life, but not critically. For example, if you overheat your battery capacity every day, it will decrease from 100% to 80% not in 2 months, but in 1.5-2 years (>80°C).

❌ Myth 4: “Switching off the nuclei CPU via 'CPU Tuner' saves from overheating."

✅ Truth: Forced shutdown of cores can increase heating, as the remaining cores will work with more load. → Battery. → Regimes).
