I got my new iPhone 5s today. Opened the box, powered it on, and went through the setup steps. When completed I went on to turn on the battery percentage and noticed there was 25 mins do usage and slightly over 2 hours of standby time in "TIME SINCE LAST FULL CHARGE." Is this normal for a brand new iPhone? Everything does look new and the box was indeed in the plastic wrap when I picked it up from Apple store. I doubt it was a returned unit as I don't think Apple store would plastic wrap it and sell it as new if it was previously used. I'd admit it bugs me a bit as I keep thinking what gives then. Has anyone seen this on your phone when you first opened it? The phone was already with iOS 7.0.2 right out of box too.
