The Power Button rattling should not be news... bad Apple! That would've never survived the SJ test.

If it is the camera, then shaking it would probably be a bad idea. Does the camera have moving parts?

I have an iPhone 5, and now an iPhone SE. Never once noticed it rattles. Now, after shaking and holding it to my ear, it does faintly, but really... Is that an issue to even comment on?!
