I never liked reading books cover to cover and still don't. But I find that new (or different to the usual) quiet environments make it a lot easier to concentrate. For me the public library is one of those places. I put my phone on silent and can read for few hours at a time. I can even read more when I sit in the bathroom, than I do on my regular chair at my desk.

It works the same for me with sleeping. Whenever I start being uncomfortable on my bed, I switch to sofa for a while.
