Unfortunately, Apple doesn't detail the "Usage" part on the phone..
I could use my phone for 1H playing a 3D game and it could drop 20-30% and someone else might use the phone for 1h browsing internet and it could only drop 10%...
so for people who gets paranoid... just look at your usage... I updated and I don't know or notice that much of a change in my battery.. but I still use it like usual and it lasts me the day so...
Also.. I know many people mentioned it but turning off the battery percentage REALLY helps. After a while you forget all about it and never look at the battery until it gets red
