What is overheating and why is it a problem?

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.

What are the common causes of overheating on OnePlus 12r?

There are several factors that can cause overheating on OnePlus 12r, such as the charger, the cable, the port, the software, the usage, and the environment. Here are some of the common causes of overheating on OnePlus 12r:

  • Using a non-standard or incompatible charger or cable. The OnePlus 12r requires a Warp Charge 65W charger and a Warp Charge 65W cable to achieve the maximum charging speed. Using a different charger or cable may result in slower or incompatible charging.
  • Having a dirty or damaged charging port. The OnePlus 12r has a USB Type-C port that can accumulate dust, dirt, lint, or moisture over time. These can interfere with the connection and reduce the charging efficiency. A damaged port can also cause slow or inconsistent charging.
  • Running a software update or a background process. The OnePlus 12r may slow down the charging speed when it is updating its software or running a background process that consumes CPU or GPU resources. This is to prevent overheating and battery degradation.
  • Using the device while charging. The OnePlus 12r may also slow down the charging speed when it is being used while charging, especially for intensive tasks such as gaming, streaming, or video calling. This is because these tasks generate more heat and consume more power, which can affect the charging performance.
  • Exposing the device to extreme temperatures. The OnePlus 12r has a built-in temperature sensor that monitors the device’s temperature and adjusts the charging speed accordingly. If the device is too hot or too cold, it may lower the charging speed to protect the battery and the device.
  • Gaming or using the camera for a long time. 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 12r has a Snapdragon 8 Gen 2 processor, which is a powerful and efficient processor, but it also generates a lot of heat when used for a long time. It also has a 6.74-inch AMOLED display with a 1440x2772 resolution and a 120Hz refresh rate. Moreover, it has a triple camera setup with a 50MP Lytia 808 sensor, an 8MP periscope lens, and a 2MP ultrawide lens.

These features make the OnePlus 12r an excellent device for gaming and photography, but they also generate a lot of heat when used for a long time. The OnePlus 12r has a dual cryo-velocity cooling system with a large vapor chamber that 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.

What are the solutions for overheating on OnePlus 12r?

There are some simple and effective solutions for overheating on OnePlus 12r. 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 or when charging.
  • 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. You can access these features by going to Settings > Apps & Notifications > App Info and Settings > Battery > Battery Optimization.
  • 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. You can access these features by going to Settings > Display > Brightness and Settings > Display > Refresh Rate.
  • 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. You can check for software updates by going to Settings > System > System Updates. You can also update your apps by going to the Google Play Store or the OnePlus Store and tapping on the Update All button.


Overheating is a common issue that can affect any smartphone, including the OnePlus 12r. 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 12r and enjoy its amazing features without any hassle.
