Erm, are you serious? Why do you do that?! ¯\_(ツ)_/¯I power up my phone every morning and once during the day. I don't keep it on when I'm not using it and don't like waiting around for it to boot up. I'm running iOS 9.3.5. It takes 32 seconds to boot a iPhone 6+.
Interesting videos. I watched the "X vs XS" video and turned my 6S on at the same time. It got to the "enter passcode" screen the same time as the X got to the lock screen. 16GB, iOS12.1 beta 2.
