I just got my iPhone 5S replacement from the Apple Store.
The (very nice) Genius did a full diagnostic on my old iPhone 5S and told me that the actual battery is fine, it was just having major software issues and crashes. I was surprised because I hadn't been experiencing many crashes or issues with it. He asked if I had set up the iPhone as a new one and not restored from a backup, I set up all my apple devices as new whenever I restore. He told me that I should be getting around 8 hours of battery life, to which I replied I would be really happy with the phone if it lasted that long.
He replaced it for me anyway because Applecare had already authorised it, so hopefully this new one lasts like it should
