I'm on Sprint (not that it matters), and I love the 1800 battery. I got it a few weeks ago and by the end of most days I'm still in the 60-70% range. I don't talk all that long, maybe 1-2 hours a day at most. With the original battery there were days when I was down to 30% by dinnertime, which is kind of scary if I was out somewhere and needed to use the phone.

I also have the 3000mah battery and I hate it; it's ridiculously huge, and I don't even wear tight pants.

quick edit: some of the increased performance for my 1800mah battery is likely due to the fact that it's just new, of course.
