Rattling in Phone when it vibrates

[AHDuke99]

So I got my latest iPhone replaced because of battery issues, but this one I have has a rattling noise whenever the phone vibrates, especially when I flip the vibrate switch. Is this a known issue? Has anyone else heard of it? Sometimes when I shake the phone, it vibrates fine, but other times, it sounds like something is loose. Should I go request ANOTHER replacement, my 4th?

I had the same problem with mine. Apple swapped it out for a new one for me. The phone should not rattle.

I'll take it by today. It rattles whenever it vibrates, not just when I switch the ring/silent button.
