Yep, look at those blue tick marks at the bottom of the graph. That shows the periods of time that the phone was active in some way (screen on, wifi on, network use, etc). From the graph, it seems like that was pretty much never.

By contrast, here's what my phones same battery readout looks like:

EDIT: Something to note about my battery life: I've used my phone a lot today, as can be seen from the photos, and I'm only down to %84 battery since charging it last night. The reason for that is because I bought an after market battery for my phone that increases it's capacity nearly x3. I find the added size not just manageable, but preferable. The extra weight and size in my hand makes the phone more hefty, which is exactly what I like.
