How to enable the battery percentage meter on my iPhone 5?

I recently purchased this iPhone five about a week ago and I'm trying to find out how to enable the little battery percentage meter that you see on the iPhone 4S I tried checking over all the settings and I can't find it if anybody is willing to help me with this situation it would be greatly appreciated

It should be under usage.

Settings >> General >> Usage >> Battery Percentage. I think its the same for iPhone 5 as it is for my 4S.
