Apple makes an effort to keep bluetooth and wifi always-on by requiring the user to go into settings to turn the settings off. The control center (quick setting toggles) does not fully turn off wifi nor bluetooth. If either is toggled off, the phone turns both on automatically back around midnight. The iphone also can connect to devices like airpods via bluetooth while being in the 'pretend off' state.
