I hope so. Just by switching to a Cortex A7 or A53 @ 22nm instead of Cortex A8 @ 45nm, this should add 78% more battery life (according to the benchmark of Ars Technica). And by having a round battery instead of a square one, 57% more capacity. So if this 360 lasts 12h, we're looking at more than 33 hours of battery life. But the 78% improvement with a Cortex A7 would be under heavy load, probably not the same story for IDLE usage.
