Hey, Siri now works even when your iPhone 6s is off the charger

On earlier iPhones, like the iPhone 6, the command will work only when the phone is plugged in the charger.We also walk you through the process of changing the language in Siri. Apple now supports some 15 languages - and many come with varying dialects. So how do you do it? Follow the steps right below.
Note that this tutorial is for iOS 8.x devices and works on the iPhone 6, iPhone 6 Plus, iPhone 5s, iPhone 5, and iPhone 4s, as well as modern iPads and iPad minis. Earlier iPhones like the iPhone 4 do not support Siri.
