> What really sucks about the more recent ios versions is that they make it a little counterintuitive to shut off your radios when you don't need them. If you want to actually shut off your wifi or blutooth its in your Settings app, the buttons in the control center don't actually shut things off.

This annoys the absolute hell out of me.

I have made a habit of doing the same when I'm going somewhere remote that doesn't have service, else the phone will thrash the battery to death vainly searching for signal.

The phone looking for signal issue could have been solved when cellphones first came out even. The phone internally knows what cell tower its pinging. You flag ones around the fringes of known no service areas like a natural park. If the user hikes off into the woods, the phone is capable of knowing its going into a no service area based on the id of last cell tower its pinged and the fact that its just lost signal for longer than 30 seconds. At which point it could switch to hunting for signal every 10 minutes or something with better compromises for battery life and realistic expectations given the area.

This annoyed me too, but I worked out a solution to having to go into Settings or airplane mode every time you want to disable wifi: Make a Shortcut for it and make that shortcut an icon on the home screen.

I made a Shortcut icon named All Off that fully turns off WiFi, Data, and Bluetooth with one press. Easy to set up in the Shortcuts app.
