That may be true, but at least the genes for night owls are present in more people than the genes for early birds.

So it should be expected that, regardless of phone usage, over half of the population will go to bed and wake up ~2-3h later than expected.

If your timezone is closely aligned with the sun, that’d be 22:00-06:00 for early birds and 01:00-09:00 for night owls. But if your timezone isn’t, both of these times would shift around.

For me personally, no matter when I go to bed, whether it’s 22:00 or 03:00, I always wake up precisely 09:30 without any alarm clock. But this also means if I have to wake up earlier, e.g. at 8am, I’ll be very tired and not well rested.
