It would only work if the iPhone was plugged into power AND they had turned on the capability for Siri to be activated by voice, which is limited to when the iPhone is plugged in.

I know Android users might not understand this limitation, but there it is.

The iPhone 6s, and the Apple Watch, are always listening (if enabled) for "Hey Siri", even on battery.
