Face ID is a sophisticated facial recognition system designed to work accurately under various conditions. When the device on which Face ID is configured is damaged, such as having a cracked front camera or issues with internal components, it can impair the functionality of the Face ID feature. The system relies heavily on a properly functioning TrueDepth camera to capture the user’s face and produce a secure authentication.

Other factors, while they may influence the user experience, do not directly cause Face ID to fail if it has been set up correctly. Fast user switching can allow for multiple user accounts but doesn’t inherently affect the Face ID technology itself. A recent app update could potentially introduce bugs, but this is less likely to disrupt the core functionality of Face ID unless it directly impacts the system settings or camera functions, which is relatively uncommon. A full battery indicates that the device has sufficient power, which is a prerequisite for all functionalities, including Face ID; thus, it would not cause failure in operation. Therefore, a damaged device is indeed a significant factor that could lead to Face ID failure.
