Memory Rundown

Hi Guys

My XT1092 has 16Gb

I have hardly installed 20 apps and have shot a mere 400 Megs of photos and videos since I installed 5.1

Now look at the memory, it seems to be all over the place, me no compute these informations, not making much sense to me. It's looking like I'm in trouble or soon to be. Any help understanding this analysis would be most welcome. Or is there a major thread about this, I would love to read it. My search was unsuccessful.

Here are some screenshots:
