I was hoping they had finally bumped it up to 2gb, but I guess not. I often read this is related to battery life, can anyone corroborate?

DRAM requires periodic refreshing or the cells lose their memory. This refreshing uses energy. More bits, more energy. You get the same issue with SRAM (think CPU caches) though without the refreshing.

Yes, DRAM requires power to refresh its memory. That's why computers can't use DRAM as permanent storage.

At least it's LPDDR3, so it should be faster than iPhone 5.
