What to do if the Xiaomi phone overheated: instructions for saving the device

Have you noticed that your Xiaomi has become hot like an iron and performance has dropped to the level of a brick? Overheating is one of the most common problems of smartphones, and you can not ignore it. At best, you will get a sudden shutdown, at worst, irreversible battery damage or even fire. Especially vulnerable models with powerful processors (Redmi Note 12 Pro+, POCO F5 Pro, Xiaomi 13 Ultra), where heat is laid out structurally.

In this article, we will not only look at emergency measures for critical overheating, but also at hidden causes that are not mentioned in the official instructions, such as why the phone can heat up even in standby mode, how overheating is associated with the use of heat. MIUI-You will also learn which Xiaomi models are most prone to overheating, and what to do if the gadget warms up even with 20% battery charge.

Signs of overheating: when to sound the alarm

Not all heating up the phone is a cause for panic. Xiaomi's normal operating temperature is between 30°C and 45°C when it's under active load (games, 4K video, fast charging), but there are symptoms that can't be ignored:

• 🔥 The body of the phone burns fingers (above 50)°C), especially in the area of the processor or camera.
• 📉 Performance plummets: apps freeze, animations slow down, games "lay down".
• 🔋 The battery discharges faster than usual (for example, from 100% to 20% in 30 minutes without active use).
• ⚠️ The system warns: "Temperature is too high. Close some applications".
• 📵 The phone spontaneously shuts down or restarts.

Local overheating is especially dangerous when only one part of the body is heated (for example, the upper left corner of the Redmi Note 11 Pro + or the center of the POCO X5 Pro). This may indicate the detachment of the thermopaste or a malfunction of an individual component (a 5G module, a memory chip).

⚠️ Note: If the phone overheats to 60°C+ And it doesn't cool down even after it's turned off -- don't try to charge it. The risk of battery bloating or short circuiting increases dramatically.

Emergency measures: how to quickly cool your phone

If Xiaomi is already “burning” in your hands, follow the algorithm:

1. Turn off the phone with a long hold on the power button (on some models - Power + Volume up). If the screen does not respond, force the power + Volume down buttons to restart for 10-15 seconds.
2. Remove the case (especially silicone or with metal inserts) - it blocks heat transfer.
3. Put your phone in a cool place, but not in the refrigerator! A sudden temperature drop can cause condensation inside the case: 🪑 Put a ceramic plate under it (takes away heat). 💨 Point the fan at minimum speed (not cold air!).

Don't plug the charging in.

40°C

If the phone doesn’t turn off (hangs on the boot screen or in the app), try an emergency reset:

1. Press the power button for 30 seconds.


2. If it does not help, connect to the PC and execute the command:




adb reboot -p

The hidden causes of overheating: what warms your Xiaomi

Most users blame overheating on "weak processor" or "hot weather," but there are many more reasons for it.

One of the most insidious reasons is the hardware Trojan in the firmware. Some "custom" versions of MIUI (especially for POCO) contain mining scripts that load the processor 100% in the background. You can check this through Settings → Developer → Activity Monitor (if the partition is hidden, activate it by pressing the MIUI version 7 times).

Software solutions: MIUI settings against overheating

If your phone is warming for no apparent reason (not gaming, not charging), optimize your system first.

1. Turn off unnecessary background processes: Go to Settings → Applications → Application Management → Autorun. Turn off autorun for social networks, instant messengers and games (except for frequently used ones).
2. Limit performance: Activate Battery Mode in Settings → Battery Modes → Battery Modes → Saving Charge. For games: in Settings → Special Features → Optimize games, select Balance or Energy Savings.

Update the firmware

• Sometimes overheating is caused by a bug in MIUI. Check for updates in Settings → About Phone → System Update.
• If the problem started after the update, see the FAQ how to roll back.

For models with Qualcomm Snapdragon (e.g., POCO F4 GT, Redmi K60) it is useful to disable the dynamic acceleration core:

1. Enable the Developer Mode (click 7 times on the MIUI Version).


2. Go to Settings → Additional → For developers.




3. disable Optimize MIUI performance.

💡

If your phone is warming up when connecting to Wi-Fi, try changing your router channel to 5GHz (in your router settings). Some Xiaomi models conflict with 12-14 channels at 2.4GHz.

Hardware problems: when to carry in the service

If the software methods didn't work, the problem is ironic.

• 🔋 The battery is swollen (the body is deformed, the screen “steps away” from the frame).
• 📱 The phone warms up even when it is turned off (for example, when charging).
• 🔌 The swelling is a slingshot (or a slingshot) or a slingshot.
• 📡 Antenna modules (5G, NFC) They stopped working and the body was warming in their area.

The cost of repair depends on the problem:

⚠️ Warning: If you notice white plaque on the board (oxidation) or the smell of burning when disassembling, do not turn on the phone. This is a sign of a short circuit that can lead to a fire.

Xiaomi models with liquid cooling (Black Shark, POCO F5 Pro) overheating is often associated with leakage of heat-dissipating fluid, in which case the repair will cost 8,000-20,000 ₽, Replacement of the entire cooling system.

Prevention: How to Prevent Overheating in the Future

To Xiaomi does not turn into a “pocket stove”, follow the rules:

• 🔋 Charge correctly: Use the original power supply (especially for models with Fast Charge 3.0)+). Do not play or shoot video while charging. Remove the case when using wireless charging.
• 📱 Control the load: Close background apps through Recent → Close everything. FPS in games (in the settings of the graphics, choose) 60 Hz instead 120/144 Hz).
• 🌡️ Keep an eye on the environment: Do not leave your phone in direct sunlight (even in your car); Avoid wet spaces (bathroom, kitchen while cooking).

For advanced users: install the CPU Monitor or AIDA64 app to track the temperature of the CPU cores in real time. Normal values for the Snapdragon 8 Gen 2 (e.g., Xiaomi 13 Pro):

• 25–40°C – Standby mode;
• 40–60°C – video or video shooting
• 60°C+ is critical overheating.

💡

Regularly (every 3 months) clean the charging connector from dust and debris with compressed air. The accumulated dirt worsens heat transfer and can cause short circuit.
