Xiaomi smartphone overheated: how to cool quickly and safely?

Why Xiaomi Smartphones Are Warming and When It’s Dangerous

Xiaomi smartphones, from budget Redmis to flagship Mis and POCOs, are not immune to overheating. Even new models with Snapdragon 8 Gen 2 or Dimensity 9000+ processors can heat up to 45 to 50°C under intense load. But when does heat become a problem?

Normal operating temperature for Xiaomi is 30-37°C. Exceeding to 42-45°C already requires attention: at this temperature, the battery degrades 2-3 times faster, and the processor begins trottling (forced performance reduction).°C and above: there is a risk of sudden shutdown, damage to the motherboard or battery bloating. AMOLED-screens (e.g. Xiaomi) 12T Pro or Redmi K60), where the display itself generates a lot of heat.

The causes of overheating are divided into two groups:

• 🔥 Hardware: faulty battery, the heatpast on the processor is dry, dust in the charging connector or under the back cover.
• ⚙️ Software: background processes, viruses, games with high graphics settings (Genshin Impact, Call of Duty Mobile), simultaneous work GPS/4G/Bluetooth.

If the smartphone is heated to 40-45 ° C, it can be cooled yourself. At temperatures above 50 ° C (there is a warning about overheating on the screen), immediately turn off the device and let it cool in the shade.

Emergency cooling methods: what to do right now

If Xiaomi is hot as an iron, follow the algorithm:

1. Turn off the smartphone (press the power button for 10 seconds) This will stop heating the processor and battery.
2. Remove the case, it retains heat, especially for silicone or thick armored cases.
3. Put the phone in the shade (not in the sun!) on a flat surface. Don't put it in the fridge or freezer - a sharp temperature drop will damage the condensers on the board.
4. Use external cooling:

• ❄️ Fan: direct airflow to the back cover (not the screen!) USB-laptop-fan.
• 🧊 Cold compress: wrap the ice in a towel and apply it to the top of the body (where the processor is!
• 📱 Cooling stand: for gamers sold racks with coolers (for example, Black Shark FunCooler Pro).

⚠️ Warning: Never blow your mouth on your smartphone, as moisture from your breath can condense inside your body, and avoid “folk” methods like diving into water or wrapping with a wet cloth, which will lead to short circuits.

Xiaomi settings to prevent overheating

If your smartphone is warmed regularly, set it up correctly:

1. Optimization of productivity

• 🎮 Limit it. FPS in games: in Settings → Special facilities → Select the resolution and frame rate 60 Hz instead 90/120/144 Hz.
• 🔋 Enable Battery Mode: Settings → Battery. → Battery mode → Balanced (for MIUI 14+).
• 🚫 Turn off background activity: Settings → Annexes → Permits → Auto-Run and Ban Auto-Run Unnecessary Programs.

2. Charging control

Charging is one of the main causes of overheating.

• ⚡ Use the original power supply. Quick charging. 120W (Like the Redmi Note 12 Pro.+) heats up the battery to 40°C in 10 minutes.
• 🔌 Remove the case while charging - it blocks the heat sink.
• 📵 Do not use your phone while charging, especially games or navigators.

Mistakes that make overheating worse

Many Xiaomi users themselves provoke overheating without knowing it.

⚠️ Warning: If the smartphone warms up again after cooling for no apparent reason (even in standby mode), this may indicate that the device is not cooling:

• 🔋 Failed battery (blown, loss of capacity).
• 🛠️ Thermointerface problems (dried the heat paste between the processor and the radiator).
• 🦠 Virus or Mining Botnet (check out Google Play Protect).

💡

If your smartphone only warms up when using the mobile Internet, try switching from the Internet. 5G on 4G SIM cards and mobile networks settings → Preferred type of network. 5G-Modems (such as the Xiaomi 13 Pro) consume 30% more power than the X-rays. 4G.

Hardware solutions: when software methods do not help

If Xiaomi is warming up even after resetting, the problem may be the hardware.

1. Thermopaste replacement

In Xiaomi smartphones, the thermal interface between the processor and the radiator dries up over time. This is true for models older than 2 years (for example, Redmi Note 10 Pro, POCO X3).

• 🌡️ Fast heating to 45°C at minimum load.
• 🔄 Frequent trottling (sharp productivity drops).

Solution: disassemble the phone and apply a new thermal paste (such as the Arctic MX-4), self-repair cancels the warranty - it is better to contact the service center.

2. Cooling accessories

For gamers and users who use the camera or navigator frequently:

• 🎮 Coolers for smartphones: attached to the back cover and reduce the temperature by 5-10°C (e.g. Razer Phone Cooler).
• 🧲 Magnetic radiators: metal plates that remove heat (suitable for Xiaomi Black Shark).

Replacement of the battery

If the battery is swollen (visible from the raised back cover or screen), it needs to be replaced. The bloated battery not only warms, but can ignite. The cost of replacing the Xiaomi service is from 1,500 to 4,000 rubles depending on the model.

💡

If the heater or battery is still warmed after replacing the device, the problem may be the motherboard (for example, a faulty power controller), in which case a diagnosis is required at the service center.

How to check if your Xiaomi is too hot

Not all users know how to objectively estimate the temperature of a smartphone. Here are 3 ways to:

1. tactile: 🔥 Hot (cannot be held in hand) - 50°C and above. 🤒 Warm (but not burning) – 40–45°C. 😌 Barely warm - 30-37°C (norm).
2. Applications for monitoring: AIDA64 (showing the temperature of each processor core), CPU Monitor (tracking heating in real time), AccuBattery (monitoring the temperature of the battery).

Hidden Testing Menu

Type ##4636## in the dialer, select Battery Information. Temp is temperature in degrees Celsius.

⚠️ Warning: if the battery temperature is simple (no games or charging) exceeds 35°C, that's a reason to call the service, possible causes: a faulty power controller or a short circuit on the board.

Preventing overheating: 7 rules for Xiaomi owners

To prevent the smartphone from turning into a “warm-up”, follow simple recommendations:

1. Update your firmware: Newer versions of MIUI optimize power consumption. Check for updates in Settings → About Phone → System Update.
2. Use the light themes: On AMOLED-In the case of the Xiaomi 13 Lite, dark themes reduce the display heat by 10-15%.
3. Limit widgets and animations: In Settings → Design → Animation system, select No animation.
4. Keep your phone correctly: Don’t leave Xiaomi in your car in the summer (even in the glove compartment, temperatures can reach 60°C).
5. Clean connectors: Dust in the USB-C port or under the back cover worsens the heat sink. Clean with a soft brush every 3 months.
6. Turn off unnecessary modules: GPS, Bluetooth, NFC and mobile Internet in the background load the processor. Use Airplane Mode when they are not needed.
7. Control charge: Don't keep your phone charging all night. The optimal is to charge up to 80% and turn it off.

💡

If you shoot 4K video frequently or play heavy games, install Xiaomi’s Game Booster app.It automatically optimizes CPU load and cooling.
