Sep 19, 2016 2:43 PM in response to lgolerby sberman,Is it necessary to turn Wi-Fi off and on? Probably not. I'm sure many folks do not do this. I do, however.
There is clearly work the iPhone will do if Wi-Fi is on and, say, you're driving past places many of which emit Wi-Fi signals. The iPhone will sense this and figure out if it's a known network, etc. I'm sure there is not one right or wrong answer, but I turn off Wi-Fi when I'm not using it to improve the efficiency and battery use of my iPhone.

Sep 19, 2016 3:02 PM in response to lgolerby Michael Black,I never turn either wifi or Bluetooth off. I don't want to have to bother with flipping those on and off. Never noticed any issues with performance or battery life by leaving them on all the time. I also don't want the nags about wifi being off if I use something accessing location services, and I do have wifi calling and my phone does use that in my home and place of work.
