Battery screen incorrect info?

[kusabi]

I just got my gs4 a few days ago and I love everything about it. One thing that confuses me though is that on the battery usage page, none of my games, messaging apps, or social media sites show up. The only things displayed are screen and android system processes. This is with 3+ hours of screen on time so it doesnt make sense that it uses only a little over a quarter of the battery. Is the info displayed just glitched or something?

I think some apps don't show up individually in that screen, they'll probably be lumped into the total Android System %.
