Over the past week, I have noticed the battery on my SE has drained relatively faster than what I was generally used to experiencing when I first bought the phone almost a month ago. In settings, under battery I noticed that Spotify and Mail apps have been using about 30% each of background activity. I proceeded to turn background refresh off, but that does not seem to help. I did a hard reset on the phone as well, but again no progress was made. The phone is draining at approximately 10% a hour. There has been no change in usage from when I originally purchased the phone. The issue began when I had iOS 10.0.2 installed and continues today with iOS 10.1.1. I take what this app says with a grain of salt, but I downloaded the battery life app and it's telling me that the wear level on the batter is "almost die." I generally don't use this app, so I don't know how accurate it is. I tentatively have a Genius appointment scheduled for next Saturday. Other than doing a clean iOS install, is there anything else I can try?
