Xiaomi camera is warming up: why it happens and how to fix it

Did you notice that the camera on your Xiaomi smartphone started to get very hot during the shooting? 10/11/12, POCO X3/X4/X5, Mi 11/12 Overheating can occur in many ways, from a light, warm body to a critical heating, where the device warns the camera temperature is too high and disables the module.

In most cases, the problem is not related to a breakdown, but it is not worth ignoring it.

• 🔥 Automatic disabling of the module during a video or photo shoot.
• 📉 Decreased image quality due to thermal noise on the matrix.
• ⚠️ Risk of damage to internal components during prolonged exposure to high temperatures.
• 🔋 Accelerated battery discharge as the system wastes energy on cooling.

In this article, we will discuss the 7 main causes of camera overheating on Xiaomi smartphones, including software and hardware factors, as well as give step-by-step instructions for diagnosing and fixing the problem. K60 Pro), where heating may be associated with high load on the image processing processor.

1. High load on the processor when processing images

Modern Xiaomi smartphones are equipped with powerful cameras with support for computational photography (HDR, These functions require significant CPU and GPU resources, which leads to heat, especially on Snapdragon models. 8 Gen 1/2 or Dimensity 9000, Those who are prone to overheating with prolonged loads.

For example, when shooting video in resolution 4K@60fps or using Pro Mode with manual settings is used before 70-80% And the result is that heat from the processor is transferred to the body, and the proximity of the chamber module to the chip makes things worse.

• 🎥 High-resolution video (4K, 8K) — resource-intensive.
• 🌃 Long-exposure nighttime loads the processing processor.
• 🤖 AI filters (such as Magic Skin or AI Scene Detection is working in real time.
• 📸 Serial shooting (burst mode) with frequency 20-30 frame-of-second.

If your smartphone is warming up in these scenarios, the problem is likely hardware-software and is related to the architecture of the device.

• Reduce video resolution to 1080p@30fps.
• Turn off AI filters in camera settings (Settings) → AI camera → Off.).
• Use third-party shooting apps (such as Open Camera or GCam) that are optimized better than the standard software.

On Xiaomi models 12S Ultra and 13 Ultra Camera Overheating May Be Linked to Surge Extra Chip C1 For image processing, try turning off Ultra mode. HDR camera-setting.

2. background processes and MIUI optimization

Operating system MIUI It's known for its aggressive control of background processes, but sometimes it works to the detriment of other resource-intensive applications (such as a navigator, video chat messengers, or games) running at the time of shooting, the processor may not be able to handle the load, which leads to overheating.

In addition, in MIUI There's a smart resource allocation function that should theoretically optimize performance, but in practice often overloads the cores of the processor unevenly. For example, one core can be loaded 100%, mientras que others idle, which leads to local overheating.

How to check and correct:

1. Open the Settings. → Annexes → Permits → Autostart and disable autostart for unnecessary apps.
2. Go to Settings. → Battery. → Performance mode and select Balanced (not High Performance!).
3. Enable Developer Mode (click 7 times on Version) MIUI in the phone settings) and in the developer menu, disable Background Process Limitation.

Close all background applications before shooting|

Disable auto-start for unnecessary programs |

Switch the performance mode to "Balanced"|

Update MIUI to the latest version|

Reset the camera settings to the factory-->

If the problem persists, try resetting the camera settings:

Settings → Applications → Application Management → Camera → Storage → Clear data

Hardware problems: from dust to damage

If the camera is warming even at a minimum load (for example, when opening the Camera application without shooting), the cause may lie in hardware malfunctions.

Critical point: if the camera warms to the point that a temperature warning appears on the screen, and the body becomes hot to the touch (more than 45).°C, immediately stop using and contact the service. Prolonged overheating can damage the matrix or processor!

For self-diagnosis:

• Check if the camera is warming in safe mode (press the power button). → Safe Mode. If not, software is a problem.
• Install a temperature monitoring app (for example, AIDA64) And check the sensors.
• Examine the chamber module for physical damage (cracks, bloating glass).

4. Software bugs and firmware errors

Firmware errors MIUI Or camera drivers, which is a common cause of overheating, like in 2022, Redmi Note 11 Pro users.+ Massively complained about the heating of the camera after updating to MIUI 13.The problem was due to the malfunctioning of the video stabilization algorithm, which loaded the processor to 100%.

How to determine what is to blame for the software:

• 📱 The camera started warming up after the update MIUI.
• 🔄 The problem appears periodically, not constantly.
• 🛠️ System logs (can be checked through the Mi Debug Tool) have errors associated with the camera_hal or media_server.

Solutions:

1. Reverse the firmware to the previous version (if the problem occurred after the update). ROM Xiaomi.
2. Cleaning the camera cache: Settings → Annexes → Camera. → Warehouse → Clear the cache
3. Reset the camera settings to factory (see the instructions in the previous section).
4. Install custom firmware (e.g. Pixel Experience or LineageOS) if you are an experienced user.

If you're not sure about your skills, wait for the official patch from Xiaomi. Usually, overheating bugs are fixed within a few minutes. 1-2 months after mass complaints.

💡

Before rolling back the firmware, be sure to back up the data through Settings. → Additionally. → Backup and reset: improper rollback can lead to a device "brick!

5. Camera settings are incorrect

Many users are unaware that incorrect camera settings can lead to overheating, such as the enabled Continuous Autofocus (CAF) Or object tracking causes the processor to continually analyze the scene, which increases the load.

Other "hot" settings:

• 🔍 Scene recognition (Camera settings) → AI → Scene recognition – constantly scanning the environment.
• 🎞️ Video Stabilization (Settings) → Video → Stabilization – uses a gyroscope and additional computations.
• 📏 High resolution previews (Settings) → Preview resolution – increases the load on the graphics processor.
• 🔄 Automobile-HDR — automatically applies processing to each frame.

Recommended settings to reduce heating:

If you make videos often, try using external cooling, like a smartphone mount with a fan or a cooling case, which is especially true for bloggers who shoot long videos.

External factors: ambient temperature and accessories

Xiaomi smartphones are designed to work in the temperature range from 0°C to 35°C. When you go beyond these limits, the system begins to overheat, and the camera is the first to react to this because of its sensitivity.

Risk factors:

• ☀️ Direct sunlight – heating the body in the sun may exceed 50°C's 10-15 minute.
• 🔥 Indoor heat (such as in a car in summer).
• 📱 Use of thick materials covers (silicone, leather substitute) that block heat transfer.
• 🔋 Charging during shooting - increases the load on the system.

Operational tips:

• Avoid shooting in the sun during peak hours (12:00 to 15:00).
• Remove the cover if you notice heating.
• Do not use wireless charging during shooting – it heats the device stronger than wired.
• If your smartphone is overheated, turn it off. 10-15 minutes and let it cool in the shade.

💡

On models POCO F3/F4/F5 redmi K40/K50 overheating of the chamber is often associated with a metal body that quickly heats up in the sun. Use thin covers made of fabric or plastic for better heat transfer.

7. When to contact the service center
