Turn off WiFi Permanently
I have unlimited data on my phone plan but not of my home WiFi. Because of this I turn off the WiFi on my phone when I get home from work. With the new iOS update my phone WiFi comes on at midnight. How do I stop this?

Don't use Control Center to turn off Wifi. This was changed to only toggle off Wifi, but not fully turn it off.
Go to Settings > Wifi and turn it off
or simply say "Hey Siri, turn off Wifi"

Turn it off in settings instead of in the control center.
Then you have a defective phone. Schedule an appointment at your Apple Store Genius Bar for evaluation. If I turn off Wifi in settings (not Control Center) mine behaves as it should and Wifi stays off until I turn it back on.
I've done this but it still turns back on in the night.
