This is my typical range. I don't leave apps running that I'm not using. Nothing is tracking my location besides Find My IPhone that I can control, and I only have one app allowed to do any background updating. I only charge my phone when it hits 1% or dies. I did the same with all my other iPhones and had no battery issues.
I also leave my phone on airplane mode overnight. I set it on airplane mode around 10pm and turn it back off when I get up. Not only does it save power it doesn't make noise or go nuts. Anyone that needs to reach us in emergency situations knows how.
