A few thoughts.
- I do think the UI is less than ideal. It does say "Disconnected from", which is unambiguous enough, but that message is easily overlooked.
- It's also problematic that the toggles in Settings behave differently.
- It seems obvious to me that 3D Touch on those two toggles should give me more options. Why can't I directly pick a Wi-Fi network from Control Center? Other Control Center menus like AirDrop and Timer have various submenu options, and this one seems obvious to add. Thus, I'm guessing they eventually will — they just haven't gotten around to it.
Now, as for the user perspective:
- Continuity highly depends on a perception of 'it just works'. When it does, stuff like unlocking your Mac with the Watch, copying and pasting between Mac and iPhone, and so forth are quite amazing. When they don't, they are infuriating. And when you have to start fiddling with stuff and manually configuring things like "well, you gotta turn Bluetooth and Wi-Fi and this and that on first", the suspension of disbelief breaks.
- Another feature that depends on Wi-Fi and/or Bluetooth when you don't expect it to? Location Services. These two taken together explain why users might have a perception of "well, I don't really need Wi-Fi", then confusingly end up with a broken user experience.
Then there's the question of why you would turn off Wi-Fi and/or Bluetooth at all. In this thread, I've seen:
- Privacy, security. Theoretically, the radios do expose you more, although I suspect the cellular connection is a far bigger factor here. Taken together, if you want to go incognito, toggling Airplane Mode is probably a much better call: it turns virtually all radios off (including GPS and NFC, I think?), and it then lets you manually turn Wi-Fi back on if you desire.
- "I don't currently need it." I don't know what that means, exactly. You also don't currently need app x, y, z to be installed, or photo A or music track B to be on your device, but you don't remove those just because. There seems to be an excessive concern here that you need to manually manage your device, when it can probably do so much better itself.
- Save battery. That's a more concrete variant of "don't currently need it". However, this idea is based on outdated assumptions — in the 2000s, the radios did make up a significant portion of your phone's battery life, but these days, they do not. The chips have gotten much smarter at shifting to low-power modes while idling. You're probably chasing a problem that isn't there.
In conclusion:
- I don't care much either way about Bluetooth, but the 3D-touching the Wi-Fi toggle should simply let me choose to disconnect from the network, disable Wi-Fi altogether, or pick a different network. And the Settings pages for Wi-Fi and Bluetooth should be similar to that.
- Apple should have done a better job communicating this somehow.
- The problem you're trying to solve probably isn't there. Want to save some battery and/or go a little more private and secure? Turn on Airplane Mode. Done.
