How's the battery life on the Nexus, and how's the PenTile screen, if I may ask?

I've been curious about the controversy around the pentile display, but I haven't physically seen one in my own hands to get my own evaluation of it.

I've set a Nexus, SGS3, iPhone4S and iPad3 all next to each other. Unless your eyes are truly fantastic or you're viewing an image designed to show off one or the other's exact display, you'll not notice the difference. At 300+ ppi (on all those displays) you're probably never going to notice a difference. Color quality, saturation, viewing angle? Those all matter far more than the sub-pixel arrangement. Just go look at an S3 or Nexus in the store and see if you like it.

Bona fides: I own an S1, S3, iPodTouch(2G), iPad3, GalaxyTab10.1 and Galaxy7. I work for a company that develops mobile apps and it's my job to know about these devices.

Battery life is average... it is the only thing I would want to improve (and probably will with a higher capacity battery). With everything on (syncing, auto-brightness, wi-fi, GPS) I get a day's worth of use (9am-11pm and about 2.45 hours of screen-on time). With my crappy old HTC Snap (Windows mobile 6.5) phone without any syncing features I could go 2 days without charging and I kind of miss that.. especially when travelling. But I'm sure I could turn off all the syncing on the GNex and achieve at least a day and a half if I really wanted to (but then what's the point)

Pentile HD is gorgeous despite all the negative you might've heard. I thought I'd be really picky too and was even considering the HTC One X due to it's superior display... but as I squint closely at the details on the Nexus' screen, it almost looks like my home screen is printed on high quality photo-paper. The only time you might notice the pentile arrangement is if some app prominently featured single-pixel white lines all over the place. I've also heard somewhere that solid white colours aren't represented correctly and appear a little yellowish or something, but so far I haven't noticed or it just hasn't bothered me. What I did notice, however, is how rich and dark the colour black appears. I was watching Kung Fu Panda 2 on Netflix the other day with my nephew and I noticed that in certain dark scenes I couldn't tell where the screen ends and where the bevel begins.

These impressions might all be tinted with my sub-standard experience with the HTC Snap before this so take it with a grain of salt (Although I did use an iPad 2 for several weeks and also have experience with my brother's iPhone 4 and with both I felt very limited in what I could do and at certain points felt downright annoyed)
