Why does the phone heat up during a WhatsApp call - briefly?
The primary reason your phone heats up during a WhatsApp call is due to increased CPU and GPU usage. These components work harder to process the call data, decode audio and video, and maintain a stable connection, resulting in heat generation.
Why does the phone heat up during a WhatsApp call - in detail?
The heating of a phone during a WhatsApp call is primarily due to the intensive use of its hardware components, particularly the processor and modem. When you make a voice or video call, your phone's processor works hard to encode and decode audio or video data in real-time. Additionally, the phone's modem is active to transmit and receive data, which also generates heat.
Moreover, the screen remains on during the call, consuming power and generating additional heat. The battery, while providing power to these components, also heats up due to its own inefficiencies. All these factors combined lead to a noticeable increase in the phone's temperature during a WhatsApp call.
To mitigate this issue, you can try to reduce the screen brightness or use a cooler case for your phone. However, it is important to note that some heating is normal and expected during intensive activities like calls or gaming. If your phone becomes excessively hot, it may indicate a hardware problem that requires professional attention.
