How to find out the temperature of the Xiaomi smartphone: 7 proven ways

Your Xiaomi is hot like an iron and your battery goes down in an hour, or do you just want to monitor the condition of your device to prevent it from breaking down? Your smartphone temperature is a key indicator of its health, but not everyone knows how to measure it correctly. In this article, we will discuss all available methods: from hidden menus. MIUI to third-party applications, and explain what values are considered normal for different models of Redmi, POCO and flagship lines Xiaomi.

Overheating can occur not only because of heat or games — sometimes the fault of background processes, a faulty battery or even viruses — we will show how to distinguish temporary heating from critical failure, and give a checklist of actions if the temperature exceeded safe values. At the end of the article, you will find answers to common questions, such as: “Why does Xiaomi warm up when charging?” or “Is it possible to use a phone at 50?”°C?».

MIUI Integrated Tools: Where to Watch Temperature Without Apps

The manufacturer hid the temperature data deep in the system menus, but it can be found without installing third-party software. MIUI 12–14, including the Redmi Note 10/11/12, POCO F3/F4/F5 and Xiaomi flagships 13/14. The main advantage is that root access or unlocking of the bootloader is not required.

To open the hidden menu:

1. Open the Phone app.
2. Enter the combination: ##4636### (on some models it may not work – see the alternative below).
3. Select the Battery Information item.
4. Scroll down to the Temperature block - here data from the battery and processor sensors are displayed.

If the code doesn’t work, try an alternative path:

• 📱 Go to Settings. → The phone.
• 🔄 Tap 5-7 times on the item Version MIUI, until you have been notified you have become a developer!.
• 🔧 Return to the main settings menu, open additionally → For developers.
• 🌡️ Find the battery condition - here will be the temperature in degrees Celsius.

⚠️ Note: On some models (e.g, POCO X3 Pro) the developer menu temperature can be displayed in tenths (e.g, 358 = 35.8°C. Not to be confused with an error!

2. Specialized applications: top-5 monitoring-utility

If the built-in tools don’t show the full picture (for example, there is no data on individual CPU cores), use third-party applications. We tested dozens of utilities and selected the 5 most accurate and safe for Xiaomi:

For accurate analysis, we recommend using AIDA64 or CPU These applications not only show the temperature of the processor (Snapdragon or Mediatek), but also other components:

• 🔋 Battery - normal up to 45°C on charging, up to 40°C to the plain.
• 🖥️ Processor (CPU) — safely up to 70-80°C under load (games, benchmarks).
• 🎮 Graphic accelerator (GPU) — cliff-point 85-90°C.
• 📡 Modem - can warm up to 60°C at weak network signal.

3. Normal and critical temperature values for Xiaomi

What is normal heating and what is a cause for concern? We have compiled data on popular Xiaomi models based on user tests and reports. Please note that values can vary depending on the operating conditions (ambient temperature, case, background tasks).

⚠️ Warning: If the battery temperature exceeds 50°C, this could lead to:

• 🔋 Accelerated wear (capacity loss by 20-30% per year).
• 💥 Risk of electrolyte swelling or leakage.
• 📉 Automatic shutdown of the phone (protection against overheating).

For example, the Redmi Note 11 Pro+ fast-charging (120W) Battery temperature can rise to 45-48°C is the norm if after the charging is turned off, it drops to 35.°C in 10-15 minutes, but if the case stays hot for more than an hour after a game of Genshin Impact, it's an occasion to check the thermal paste or cooling.

4. Causes of overheating: from harmless to critical

If your Xiaomi is warming up like a stove, first determine the cause. We divided them into 3 categories by degree of danger:

🟢 Innocuous (removed independently)

• ☀️ Heat or direct sunlight - even in the shade +30°C the body may be heated.
• 🎮 Games/Benchmarks – Snapdragon 8xx Mediatek Dimensity is warming up under the load.
• ⚡ Fast charging – especially on models with support 67W/120W.
• 📶 Weak signal network – modem is working at maximum, warms up.

🟡 Need attention (may need to adjust)

• 🦠 Viruses or Mining Programs – Check in Settings → Applications of unfamiliar processes.
• 🔄 Cyclical reboot of background tasks – for example, cloud or mail synchronization.
• 📱 Unoptimized firmware - especially relevant for custom ROM (For example, the Pixel Experience).
• 🔋 Worn-out battery (capacity) <80%) — Checked out at AccuBattery.

🔴 Critical (repair required)

• 🔥 Dried thermopaste – for phones over 2 years old.
• 💧 Liquid intake - even after drying, oxides may remain.
• 🔌 Faulty power controller – phone warms up even when switched off.
• 🛠️ Damaged motherboard – often after falls or bumps.

To diagnose the problem, perform a step-by-step check:

1. Close all the apps and leave the phone down for 10 minutes, and if it's cold, it's the software's fault.
2. Check the temperature in safe mode (press the power button). → Safe regime).
3. Install. AIDA64 And see which component is warmed the most.
4. If nothing helps, go to the service center.

💡

If the phone is warming up while charging, try turning off fast charging in the battery settings. - On Redmi Note 12 Pro models+ This can be done in the settings → Battery → Charging settings → Turn off accelerated charging.

5. How to lower the temperature: working methods

If the cause of overheating is not critical, try these methods. They will help reduce the temperature by 10-20°C without harming the phone:

📉 Programmatic methods

• ❄️ Enable energy saving mode – limits background processes.
• 🚫 Disable unnecessary applications in Settings → Annexes → Auto-start.
• 🔄 Update. MIUI — In new versions, heat is often optimized.
• 🎯 Limit it. FPS in games (e.g. in games) PUBG Mobile or Call of Duty).

🛠️ Hardware techniques

• 🧊 Remove the case – especially if it is dense or silicone.
• 🌬️ Use a cooling stand (e.g. Black Shark FunCooler).
• 🔋 Don’t charge your phone while playing – it doubles the load.
• ☀️ Avoid direct sunlight (even in the car under the windshield).

🔧 Radical measures (for advanced people)

• 🔨 Replacement of thermopaste – is important for phones older than 2-3 years.
• 📲 Recoil to factory firmware - if overheating began after the update.
• 🔋 Replacement of the battery if the capacity has fallen below 70%.

⚠️ Note: Do not use the Google Play cooling app that promises to lower your temperature by 30.°C per 1 click. Most of them are either useless or contain malicious code. The only exception is — 3C Toolbox, but it also needs to be manually configured.

💡

If the phone is heated to 50°C and above, immediately disconnect it from charging and let it cool in the shade.Continued use can lead to permanent damage to the battery or processor.
