"IPhone 6S-tech" doesn't have to be plugged in or "Hey Siri" at any time.

Before the iphone 6, it was only when the power was plugged in that it was possible to call Siri by saying, "Hey Siri." But for iphone 6s+ios 9, you can call Siri at any time with your voice, without having to press the home button at all!

This function is very useful at some times, like a phone on the bed, but lying on the beds of you, suddenly remembered to set the alarm clock, then you just yell: "Hey Siri, wake me up at nine in the morning!", Siri will automatically help you to complete the alarm settings. You can finish it without having to find your phone from beginning to end.

1. Go to the "Settings" App, click "General" → "Siri", and "Hey Siri" to open, you can use the voice to call Siri without plugging.
