How to find out the temperature on Xiaomi: 7 proven ways for smartphones, tablets and smart watches

Why is it important to monitor the temperature of Xiaomi devices?

Overheating is one of the most common problems Xiaomi smartphones can cause sudden shutdowns, performance loss or even battery damage, especially for flagship models (Xiaomi 13 Ultra, Redmi Note 12 Pro+) and low-cooling devices. But how do you know if the phone is overheating? And most importantly, how do you accurately measure its temperature?

In this article, we will discuss all available methods: from built-in tools MIUI You'll learn which metrics are considered normal and which are critical, and what to do if the device is too hot.°C is normal, but if the difference is greater than 20°C, it's worth checking the cooling system.

Let’s start with the simplest methods that do not require additional software installation.

Method 1: Integrated temperature monitoring in MIUI

Modern versions of MIUI (starting with MIUI 12) have a hidden section with temperature data for key components to open.

1. Go to Settings. → The phone.
2. Tap 5-7 times on the MIUI version line until the notification “You became a developer” appears.
3. Return to the main settings menu and open Additional → for developers.
4. Scroll down to the Temperature Monitoring unit (on some models it is called Battery Temperature).

Here you'll see the temperature of the battery, the processor and (on some devices) the screen. For example, for the Poco F5, the normal values are simple: battery is 28-35 °C, processor is 35-45 °C. During games or charging, these numbers can rise to 50-60 °C, but if they exceed 70 °C, this is cause for concern.

💡

If there is no section for developers, update the MIUI to the latest version or use alternative methods from this article.

Method limitation: In some firmware (especially on budget models like the Redmi 10A), this section may be missing or only show the battery temperature.

Method 2: Codes for Engineering Menu (USSD)

Hidden engineering menus allow you to get advanced information about the state of the device, including the temperature of the sensors. USSD-code:

• 📱 ##4636## - General test menu (Battery Information section shows temperature).
• 🔧 ##225## - Sensor calibration (on some models displays the temperature of the processor).
• 🌡️ ##8437## – Temperature sensor test (not available on all devices).

Enter the code in the Phone app as a regular number. If the menu doesn't open, your model doesn't support this method. Attention: don't change the settings in the engineering menu unless you're sure of their purpose - this can cause malfunctions!

Method 3: Temperature monitoring applications

If the built-in tools don't give you the full picture, install one of the specialized applications. We tested 5 popular utilities and selected the best ones:

• 📊 CPU Monitor – shows the temperature of the processor, GPU It's a real-time battery with graphs, and it supports widgets on the home screen.
• 🔥 AIDA64 — It's a professional tool with detailed information about all the sensors, and it's a paid version that allows you to log data.
• 📈 AccuBattery – Focuses on the battery state, but also displays its temperature during charging/discharge.
• 🛠️ DevCheck is a lightweight application with a minimalist interface that shows the temperature CPU, GPU battery.

To install, go to Google Play and enter the name of the app. Once you run, provide all the permissions you request (especially access to device information). For example, in the CPU Monitor, you can see the temperature on the home screen as a graph:

CPU Monitor|AIDA64|AccuBattery|DevCheck|Other/Not using-->

⚠️ Note: Some antiviruses (e.g. Avast) may block applications from accessing temperature sensors, in which case add the utility as an exception or temporarily disable protection.

Method 4: Temperature check through ADB (for advanced)

If you want the most accurate data, you can use Android Debug Bridge (ADB), which requires you to connect the device to your computer, but you can access all the sensors.

Instructions:

1. Install ADB Tools on your PC.
2. Enable USB debugging in the developer settings (see Method 1).
3. Connect Xiaomi to your computer and confirm your trust in the device.
4. Open the command line (Windows) or terminal (macOS/Linux) and type:

adb shell


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

You will get a list of temperatures of all sensors in milligrades Celsius (divided by 1000). For example, 35000 = 35°C. The following zones are usually available on Xiaomi:

• thermal_zone0 — processor (CPU)
• thermal_zone1 — graphics-processor (GPU)
• thermal_zone2 — battery
• thermal_zone3 — charger

Install ADB Tools on PC| Enable USB debugging on Xiaomi| Connect your phone with the original cable | Run the command line on behalf of the administrator-->

⚠️ Note: Not all Xiaomi models provide access to all sensors through the ADB. On some devices (e.g. Redmi) 9A) Only the battery temperature can be displayed.

Method 5: Temperature of smart watches and fitness bracelets Xiaomi

Xiaomi smartwatches and bracelets (such as Mi Band 7, Xiaomi Watch S3) can also overheat, especially during prolonged GPS use or while charging.

1. Through the Mi Fitness app: Open the app and sync your device. Go to Device Profile → Battery status. Some firmware shows battery temperature here.

• Remove your bracelet or watch and touch the body.
• Normal temperature - barely warm to the touch.
• If the device is hot (over 40°C), disconnect it from charging and let it cool.

The critical temperature for Xiaomi wearables is 50°C or higher, and when this heat is used, the charging automatically turns off, and a warning may appear on the screen.

• 🔌 Power adapter and cable (use only original power adapter).
• 🔋 Battery condition (blown or deformed).
• 🌞 Operating conditions (direct sunlight accelerates heating).

Method 6: Indirect Temperature Assessment

If you do not have access to monitoring tools, you can determine overheating by the following signs:

• 📉 Decreased performance: games start to "lay down", applications close spontaneously.
• 🔄 Sudden reboots: The device shuts down when a critical temperature is reached (usually 80-90).°C).
• 🔋 Slow charging: when heated above 45°C charging speed automatically decreases.
• 📱 Hot case: The back panel or area around the camera becomes hot to the touch.

To check the tactile temperature, use the back of your hand, which is more sensitive to heat. Normal: the body may be warm, but not burning. If you hold the phone, it becomes uncomfortable, it means the temperature is above 45-50 ° C.

💡

If Xiaomi turns off when it’s hot, it’s not always a defect. Modern smartphones have overheat protection that works at 85-90°C.

Normal and critical temperature values

To understand how serious the problem is, compare your device readings with the standard values:

⚠️ Warning: if the battery temperature exceeds 50°C during charging, immediately disconnect the device from the mains! Prolonged heating over 60°C can cause the battery to swell or even ignite.

Temperature is affected by:

• 🎮 Games and heavy apps (such as Genshin Impact or Call of Duty Mobile) can load a processor up to 100 times%).

What to do if Xiaomi overheats?

If your device’s temperature regularly exceeds the norm, use these tips:

1. Remove the case - dense silicone or leather covers worsen heat transfer.
2. Close the background applications – use Settings → Applications → Launched.
3. Turn off unnecessary features: GPS (if not in use), Bluetooth and Wi-Fi (standby). Autobrightness of the screen (manual setting reduces the load on the processor).

Use a cooling stand

Update the firmware

If overheating is accompanied by the following symptoms, contact the service center:

• 🔋 The battery is swelling or deformed.
• 📱 The device is turned off at a temperature below 70°C.
• 🔥 The body is heated even in standby mode.

💡

For emergency cooling, put Xiaomi in the shade for 10-15 minutes. Do not use the refrigerator or ice - a sharp temperature drop can damage the screen!
