What is does iphone ring when dead?

When an iPhone is dead, it means that it has no power and is completely turned off. If someone calls the dead iPhone, it will not ring, and the call will go straight to voicemail. The phone will not make any sound or vibration if it is not turned on, even if it is still connected to a Wi-Fi network.

However, if the iPhone is on low power mode, it might still ring when it receives a call, but this is only possible if the battery level is high enough to power up the phone for the call to come through. Generally, it is recommended that the phone be charged before attempting to make any calls or receive any calls.
