I'm still waiting on controlled tests before I pass judgement. I am sure that it will outperform the similarly outfitted Nexus 5 (AMOLED vs IPS LCD at min), but the question is "How much more?" I mean, I could get a day out of my Nexus 5, but more often than I would have liked, I had to manage things a bit to get there. I've moved to a G3, which gets me to late at night with charge to spare, so my next phone would have to be able to get to point where I don't have to battery-watch....
I have one jump left between now and next July, which I plan in exercising later this year (because new phone), and my sights are squarely set on the new Nexus, hoping the 5.2" beastmode rumors are true... but if that turns out to be vaporware, the Moto X would be my next most likely candidate (if at all).
