This is the best battery life I've seen in a smartphone yet, but I probably have a very limited smartphone experience compared to some others on here. I don't use my phone nearly as much as most of the folks here, and I can get 3 full days. I can get through almost the full weekend on a full charge as well. I'd say that if you're expecting the battery to last 3 days with heavy use, you're expecting a lot as most smartphones I've seen will last maybe 2 days with heavy use, usually just over 1. Also remember that when you're installing stuff or tweaking your phone, that will run the battery down faster. Try to get everything setup all at once, then go for about a week or two with regular use to get a better idea of what the battery life will be like.
