My understanding is that Android systems in fact do not suspend when
the screen is on, and that most (perhaps all) other systems do not
opportunistically suspend at all.  There has been some speculation about
what a hypothetical Android having a non-volatile display might do,
but as far as I know, this is just speculation.
