My phone is set to shut the screen off pretty quickly (saves battery life).
Normally this timeout is perfect for reading a page of text. If a child walks in the room or a squirrel runs by it distracts - what was that?... oh where was I? ...oops the screen went black and I have to unlock it.
I would suggest that when I am in reading mode my phone remain active. It's much less annoying than constantly having to wake my phone up.
