I want Hey Siri only when plugged in
I have an iPhone 6s. I notice that the battery life isn't as much better than my 5s, and I was wondering what could be draining it. Turns out if I want "Hey Siri" on the 6s you need it to be on all the time. I only want it to be on when I'm at home, plugged in. I use it to set kitchen timers and stuff.
How do I do this?
