What is overheating and is it an issue?

Overheating is when a device’s temperature exceeds the safe or optimal range for its normal operation. All electronic devices generate heat, but they also have mechanisms to control and dissipate it. However, when these mechanisms are overwhelmed or malfunctioning, the device can overheat and cause problems such as performance degradation, battery drain, screen dimming, or even permanent damage.

Overheating is not the same as heating. Heating is normal and expected when a device is being used, especially for intensive tasks. However, overheating is abnormal and undesirable, as it can affect the device’s functionality and longevity. A simple way to tell the difference is by how the device feels in your hand. If you can’t hold it comfortably or near your ear, it’s probably overheating. If it’s just warm, it’s probably heating.

Why is my OnePlus 12 overheating while charging?

One of the common causes of overheating on smartphones is charging. This is because charging involves transferring energy from the charger to the battery, which generates heat as a by-product. The amount of heat depends on several factors, such as the charger’s wattage, the battery’s capacity, the ambient temperature, and the device’s usage while charging.

The OnePlus 12 supports fast charging up to 65W, which can charge the 5400mAh battery from 0% to 100% in about 40 minutes However, this also means that the battery will heat up more than usual during the charging process. This is normal and expected, as long as the device’s temperature stays within the safe range. However, if the device is also being used for other tasks while charging, such as gaming, streaming, or video calling, the heat generation can exceed the heat dissipation, resulting in overheating.

Why is my OnePlus 12 overheating while gaming or using the camera?

Another common cause of overheating on smartphones is gaming or using the camera. These are some of the most demanding tasks for a smartphone, as they require the processor, the screen, and the camera to work at their full capacity. The OnePlus 12 has a Snapdragon 8 Gen 3 processor, which is one of the most powerful and efficient processors in the market. It also has a 6.82-inch AMOLED display with a 1440x3168 resolution and a 120Hz refresh rate. Moreover, it has a triple camera setup with a 50MP Lytia 808 sensor, a 64MP periscope lens, and a 48MP ultrawide lens.

These features make the OnePlus 12 an excellent device for gaming and photography, but they also generate a lot of heat when used for prolonged periods. The OnePlus 12 has a dual cryo-velocity cooling system with the largest vapor chamber ever in any phone. This system is designed to keep the device cool and stable even under heavy load. However, if the ambient temperature is too high, or if the device is covered by a case or other objects that hinder the heat dissipation, the cooling system may not be able to cope with the heat generation, resulting in overheating.

How can I prevent or reduce overheating on my OnePlus 12?

There are some simple and effective ways to prevent or reduce overheating on your OnePlus 12. Here are some tips that you can try:

  • Avoid using your device while charging, especially for intensive tasks. If you need to use your device while charging, use a lower-wattage charger or a wireless charger, as they generate less heat than a fast charger.
  • Avoid exposing your device to direct sunlight or high temperatures, as they can increase the device’s temperature and reduce the cooling efficiency. Keep your device in a cool and well-ventilated place when not in use.
  • Remove any case or cover that may obstruct the device’s vents or trap heat inside. Use a thin and breathable case that allows the device to breathe and dissipate heat.
  • Close any unnecessary apps or background processes that may consume CPU or GPU resources and generate heat. Use the device’s built-in optimization features, such as the Game Mode or the Smart Boost, to enhance the performance and reduce the heat.
  • Lower the screen brightness and the refresh rate, as they affect the battery and the display’s heat generation. You can also enable the Adaptive Brightness and the Auto Refresh Rate features, which will adjust the screen settings according to the ambient light and the content.
  • Update your device’s software and apps regularly, as they may contain bug fixes or improvements that can enhance the device’s stability and efficiency and prevent overheating.


Overheating is a common issue that can affect any smartphone, including the OnePlus 12. However, it is not a serious problem, as long as you know the causes and the solutions. By following the tips mentioned above, you can prevent or reduce overheating on your OnePlus 12 and enjoy its amazing features without any hassle.
