2 days with 32% left isn't too far fetched.
Last night I went to bed with 100% charge. In bed I watched 20 minutes of a netflix movie (over wi-fi), then went to sleep. Almost exactly 8 hours later (when I woke up), my battery shows 92% remaining (technically it showed 93% remaining, but changed to 92% about 5 minutes after I first checked).
That's 1% (or less) per hour on idle, except that I did watch 20 minutes of a show on it as well. About 3.5 hours later after I checked facebook a couple of times, browsed the web, messed around a lot with 'rooms' (setting it up with my wife's lumia 920 as well), downloaded some apps and then played an additional 1 hour minimum of a graphic intensive game I'm now sitting at 50% battery (the game drew the most power).
This is also the 2nd time I've seen my phone drop 1% per hour on idle. It has been consistent, which means if you didn't touch your phone, at 32% battery life, you could be looking at 32+ hours before it goes dead (assuming you don't have battery saver turned on when the battery is low, which would further extend the charge).
