Simply conserving battery life?

And according to the article iPhone users that thought their Bluetooth was turned off were vulnerable to attacks; that's not a superstition.

Turning off WiFi makes your battery life worse, because you'll forget to turn it back on.

Even if you're not joined to anything, it doesn't matter. The cellular antenna is the only one that uses any significant power.

What? (I'm not OP)

Turning off Wi-Fi makes your battery life worse [because the cellular radio uses significantly more energy and you'll forget to turn it back on when you're around Wi-Fi again].

I don't use WiFi and Bluetooth frequently. I use mobile data on iOS and wired connection with macOS. Probably I'm too old now and this way of connecting devices is now a niche :)

The battery will last months if it's turned off "all the way". I think needing many months, away from a charger, is a very very niche use case.
