1. Is it dangerous if my phone gets hot during a video call?

A warm device is perfectly normal during extended video calls and is rarely a cause for immediate concern.

Apple does not offer a setting to manually lower your FaceTime video resolution. The app automatically adjusts visual quality based on your network connection speed and signal stability. However, you can turn off your camera and switch to an audio-only call, or switch from a cellular connection to a stable Wi-Fi network.

3. How long should I wait if my phone overheats on FaceTime?
