iPhone 5 rattles?

[gonz9731]

I've got my iPhone 5 in a TPU case temporarily.
The power button feels very light, almost no resistance on it. My older iPhones seem to have a slight constant resistance on the power button.
Also while in the case if I drop the phone gently onto the bed or other soft surface I can hear a rattle. I tried to hold the power and volume buttons firm while dropping it and think I've narrowed it down to that. Anyone else experience this?
TIA

Now that I look at it, my power button has a slight rattle. It's kinda sexy.

Mine does the same thing. From what I hear its the auto focus camera lens.
