Big.LITTLE has always somewhat baffled me as to how well it works. Is my phone actually good at assigning low priority tasks to the little cores? It's always seemed unlikely given how half-assed it seems to be when it comes to much easier things like not trimming the app I'm currently working with for using too much power or taking less than five solid minutes to notice I've driven away from my house's wifi and it needs to use 4G instead.
