I just woke up. This is the 5s that I just received last night. So my battery is now at in at about 70% and I haven't even left for work yet. It has lost 30% in an hour and some change. I haven't even played any games. I'm coming from the iPhone 5c, the battery on that one lasted longer. $800, this is going back. This is miraculous. It is now at 74% it's draining by the minute. I literally just watched it drain from 75% to 74% in the minute it took to write this post.
