"Oct 23, 2014 - Summary: What makes Apple's new iPad Air 2 tick? ... Processor; Elpida/Micron Technology F8164A3MD 2 GB RAM (two 1 GB chips) ... Air 2 has a smaller battery than the original iPad Air, 7,340mAh compared to 8,827mAh."
The difference in battery life is quite noticeable. The difference in mAh is about 20% but I think in actual usage the difference is closer to 25% to 30%. It's just my own experience, of course.

I agree with this. I believe the A8X may not be quite as efficient as we'd like, and the extra gig of ram draws more power in sleep. My Air was a 15+ hour device that I charged every 5 days or so. The Air 2 seems to be a 10-12 hour device that I'll charge every 2-3 days. It's totally noticeable, and while it's fine, I'm surprised how much im missing the old battery life. It was the first device where I barely ever thought about the battery.
