Anyway, thanks for posting the specs. Just one concern, how is the battery life expected to be? Does that A15 take a lot of juice? Will the 2000mAh be enough to make it functional? The Vita has borderline issues with battery life with the 2200mAh, for a phone to have around the same issue... disastrous. You mention it could have better battery life than iPhone 4s (which was disappointing wasn't it?), I want to know how so? To really get the use out of the device you'd have to enjoy high demand programs, is the iPhone 5 looking like a short lived gaming device? I'm sure running idle it lasts all day or more, but what if I play a few hours of the latest graphics pusher? Also, is there and advantage or disadvantage to a dual core?

The A15 is more powerful and it most likely has higher clock speeds than the A9 in the 4S, but it is most likely being made on the 32nm process (instead of the 45nm like on the 4S), so it is 22% smaller and uses less power.

LTE does use more power which is why Apple waited so long to implement LTE. Qualcomm's 28nm LTE chip reduced the size and power usage for LTE usage. Previous LTE chips were larger used more power.

According to the Apple website battery life is:
