Except if you have the SE there is no force-touch and you are still forced into the main settings menu. I turn off the WiFi when driving or doing outdoors stuff because I don't want the battery to drain searching for a network for 6 hours...
Perhaps it is not, but I'm thinking about using this same phone and battery for at least couple more years (had it over a year now) so I like to conserve power where I can.
I like the new wifi toggle because iPhones are AP sticky usually.
