It has been rumored for a while that the next iPhone 14 Pro and 14 Pro Max will come with an Always On mode, allowing the screen to be constantly on to show the time and various information, without unduly impacting the battery.
iPhone 14 Always On, LTPO technology and 1 hertz display
The function is already available on some Android models, and made possible by LTPO technology (low temperature polycrystalline oxide) allowing adaptability of the screen refresh rate, more particularly a display at 1 hertz. The iPhone 13 Pro and 13 Pro Max could only go down to 10Hz, and it's that 1Hz display that makes Always On mode possible.
iPhone 14 Always On, always on lock screen wallpaper
The 9to5mac site recently discovered clues in the iOS16 code as to how this mode works. We learn in particular that the screen will not go black like on Android, but that the bottom of the lock screen will remain visible, with a very low brightness of course. The brightness will return to normal when the iPhone is unlocked. The iPhone 14 range will be presented next September.
