You can still switch off the radios if you want in settings.
Every single time I've wanted to turn off Wifi and Bluetooth, it's because I know I'm going to struggle to get my battery to last till I can charge it again. I'm going to be out and on the move, so Wifi has no value to me except as a battery drain.
In fact, I struggle to think of any other ordinary use for disabling Wifi and Bluetooth. The real exceptions are like (I have this one now) I don't have ADSL at home but I haven't been bothered to turn off the modem or my mate who's paranoid of being stalked by companies. But those are exceptional. I wouldn't write a feature to deal with them. Except to keep the battery going, who turns wifi off?
It sounds like I've lost a real feature and I don't know how to get it back any more. If I want to be able to send and receive data but I want my phone to last all day, what can I do?
: NB. The only reason I want my phone to last all day is because I want to use it. Consequently, saying "my phone lasts all day no problem" isn't an answer. You probably don't use your phone like I do.
This. We can’t turn off BlueTooth/WiFi from the swipe-up screen anymore. Full stop.
