The perf/W of the SoC will probably be better than Pandora's, so I guess it probably depends on how much people need to stress it, and if they're comfortable with any reduction in battery life. I personally don't feel like I need anything like 10 hours of full load, but that's just me and I know a lot of people feel otherwise.
Of course that's also assuming that the battery dimensions won't change in some other way to compensate.. that while being thinner it isn't always higher in surface area (due to either extending out to cover more of the unit's base or the base simply being bigger in either dimension)
I'm worried not to get 10 hours of battery lifetime anymore.
This is one verry imoprtant feature for me because I don't want to charge my Pandora during the day.
What about you: Do you also think 10 hours are nececarry or would you be satisfied with less?
Do you know if there's already some progress with batteries? Will batteries which have the performance of Pandora's battery be smaler in 2013?
Craig, do you know anything battery related?
