It really varies dramatically by my usage. If I'm playing games I'll see 1-3 hours depending on the intensity of the game. If I'm browsing the web with a lot of idle time in between I'll see 3-4 hours. If I'm reading with airplane mode on I'll see up to 5 hours but that's rare. I'd say I average around 3 but that's with ~30-60 minutes of phone calls and 2 hours or so of music streaming mixed in.
