I've been using it for about three days, now. When I first got it, the size (and weight) were fairly jarring to me, as I was coming from a Galaxy S4. It felt cumbersome at first, but over the last couple of days, I've started getting used to the size and feel of it. The biggest drawback is that I can't really do one-handed texting anymore (which was nice to be able to do, because it was easier to sneakily text at work, where they don't take kindly to employees pulling out their cell phones during work time), but it's whatever.
Battery life has been fine. It's a little better than on my S4. It's obviously not going to hold up as long as a 3900 mAH battery, like the Droid Turbo's, but my usage level is fairly moderate. I made it work with the S4, while having at least half the battery left by the end of the day, so if I can do it with the S4, the N6 definitely holds up for me.
The only "performance problem" I've had is that Chrome seems a bit laggy, but then again, Chrome seems to be similarly laggy on every Android device I've used it on, so that probably has more to do with the app itself, rather than the phone.
Other than that, I'm pretty happy with it, and I'm glad I'm starting to get acclimated with it. Never thought I'd be able to handle a 6" phone. I REALLY miss Gravity Box, though. I used that to make my S4 pretty much perfect for my needs, while using a vanilla Android ROM, and I loved it. Bums me out that Xposed is not ART compatible, and may never be.
