Far as battery life goes it's not that good however, friend of mine has the note 2 with the extend battery over 2x capacity and ya thats good.
best battery life ive ever had on a smart phone. I can go two full days with moderate useage without a charge. I use my phone a good bit all day every day. Battery life is about twice as good as my last few androids.
Recent phones: One X, GS3, Note 1, Atrix 2, & Optimus G.
