On a laptop or tablet, the backlight probably draws far more juice than the CPU. So if the CPU can complete a task more quickly by not hitting the HDD or eMMC as often, the backlight won't need to be on as long, which saves power. I wonder whether this is a simple enough task to be put on the little cores in ARM's big-little configuration.
That's kind of a silly thought. It's not like the backlight gets turned off when the CPU is done. It gets turned off when the workday ends. You don't get to leave early just because your CPU compiled your code faster or that web page loaded a bit faster.
