Used to be these toggles physically turned the wifi and BT on and off entirely. Now it just enables and disables automatic connections. The radios are always on unless you drill into settings and toggle them off there. Maybe it drains the battery. Maybe it doesn't. Either way, there is zero need to mess with this. Why the hell do they constantly need to fiddle with things that need no change? Especially with functions that have remained constant for years. Edit: Having used the final version of iOS with these features. I have kinda come around on it. I notice no faster drain of battery. I'd love a 3D Touch/tap hold gesture to do a full toggle off still. I seem to also have noticed a side-effect of the always on Wi-Fi. I kee getting autoconnected to carrier operated hot spots (Xfinity, ATT, Cox, etc.) So even where I have full LTE data and I try to browse a web page real quick I get ambushed by the hot spot login sheet when I have no intention of using public hot-spots or in most cased don't have the requisite customer login TO use them. Unless I'm missing something there needs to be a way to kill autojoin for unknown APs.
