While there are a few little complaints I have about the Nexus 4, my primary ones are mediocre battery life and storage. I got a 16GB model and I have to shuffle files around (nandroid backups, roms, music) more that I'd like, but that's more of a convenience problem. Its battery life is the biggest issue, as I can rarely get through a full day on a single charge. That's why the possibility of the next Nexus being a Note sized device interests me, as those typically have good battery life. It's all rumor at this point though, but I don't plan on buying a new phone until next year anyway so It will have been out for a few months before I consider buying it.I currently have a Nexus 4 and cannot think of a single reason to get rid of it other than "want latest because it is out there." Granted, I wouldn't call myself a power-user, but it still runs butter-smooth, screen is perfectly acceptable for watching porn on the toilet, battery still does fine. I am perfectly content, but will probably get a Nexus 6 if/when they come out only because I can.
