Just like Haswell focussed on battery life rather than performance, I hope the A8 does the same.
I have a silly feeling, from the way Apple showed the exponential graph showing performance double each time when the A7 was announced, they will change focus now that the exponential nature of that improvement seems overkill. It's been 2x faster for at least a couple of generations now... Maybe it'll be more like 1.33 or 1.5x faster but 2x more efficient?
Anyone who has actually use their phone to the point where they are unhappy with the battery will tell you that the processor has almost nothing to do with power usage. It is the cellular modem that uses the most battery power. If you turn off 3G, your battery lasts forever. That's why incremental improvements to the processor are of no consequence to those of us who want more battery life.

I'm averaging 2 days and 9 hours on my moto droid maxx. If I can't get that with the new iphone I guess I will continue staying with android. Only reason I have not gone to an iPhone is screen size and battery life.
And the Razr maxX is the only android phone that actually temps me. If I didn't have seven years worth of apps and built in knowledge, I would be there in a heartbeat.
