If anyone has an issue with a 5S loose power-sleep/wake button that rattles annoyingly please report to Apple here - http://www.apple.com/feedback/iphone.html
Not all 5S units have the power button rattle but it appear many do so it's a bit of a lottery.
The more people who report an issue with the rattle the more likely Apple will address it.
