Each iPhone has installed the voice software "Siri", which allows you to control the phone via voice commands. So of course also the iPhone 6S with iOS 9 has SIRI. For Siri, there is a so-called wake-up command, with which you can start the voice control software without restarting the appropriate app on your smartphone. However, this works only with external power supply! The wake-up command is usually:
• "Hey Siri"
However, this "Hey Siri" feature must first be activated on the iPhone 6S. We tell you here clearly how and where you can find the setting on the iPhone 6S in iOS 9. For this purpose, please proceed as follows:
1. Start from the home screen of your iPhone 6S and open from there the settings
2. Tap on the "General" tab and then "Siri" to adjust the settings for voice control
3. Shifts the controller now with "Hey Siri " to "On"
From now on you must not touch the home button to launch Siri if your iPhone 6S is connected to a charger. This function is useful especially if you are traveling by car. If you have your car equipped with a car charger, you can use this function properly, to use Siri in your car.
