I've noticed that when I play a game, I can drain the battery in a matter of 2-3 hours. My guess is that most of that power drain is due to the CPU and GPU. Certainly the screen is a big factor. What would be amazing is if the OS on devices with these smaller cores would provide a mechanism for apps to request the kind of CPU they want. For example, services or background tasks could always run on the smaller core, even if they are fully utilizing the core, without getting pushed to the bigger core. This could help Android, for example, make sure that background tasks don't eat up battery life while the phone appears to be sleeping or doing other things.
