I use my iPhone 15 Pro on standby mode as my night clock etc. I have the display set to always on. I have noticed that approximately every 4 hours the display shuts off. You have to touch the screen to initialize again. Is this something in software?
iPhone 15 Pro, iOS 17
I've not tried mine for Never for Turn Display Off. I have mine set to Automatically. That way if and when it turns off, I only need to have motion in front of the screen for it to turn back on. So, in other words, if I turn over in bed, the screen usually comes back on automatically. Without movement, it turns off, at least as far as I know, since I'm asleep. The settings I mentioned are the only ones that I'm aware of for StandBy.
