The Nexus 4 that's sitting here in my office. Also, the GN2 I had for a bit. I said I get 4-5 hours EASILY syncing everything possible, auto brightness on and ramped up via my rom, and no wifi ALL LTE data. If I want to tinker, which I love to do and is what I and MOST nexus owners enjoy doing with their devices (said every poll ever to ask the question stock vs custom on Nexus devices...by a lot), I can get over 6 hours SOT...days with minimal usage. I have a 5000mah portable charger I bought for $10 that's not much bigger than a pack of gum for camping, long business trips (plane or train...no need in cars), or any other time I feel I may not see an outlet for 2+ days. So again, I would love to have a bigger battery just to have it. I don't need it and I sure as hell don't want to pay for it...as I don't need it. You battery "freaks" are WAY in the minority. If Google put a 1000mah battery and sold it for $200 it would still sell out in minutes. Same reason the 8GB version was always sold out well before the 16GB. Google makes it's money off of its services...aka every single Android device in exisitance. It doesn't want or need to sell tens of millions of Nexus devices at a few bucks over cost. It's not a non-profit company and could easily sell them for much more and still sell the same quantity. It makes them with the best of hardware components that matter to developers (aka not the f*cking camera, storage, or battery), to get the "best" of Android...aka new software... in the hands of as many developers as possible. Many devs have a Nexus as AOSP reference and then a few big selling OEM devices.That is why they are sold so cheaply...and that Google seems to care more about the general population than most for profit organizations.
