I went to the Apple Store earlier today to ask for a fix, remedy, or entire replacement.
The genius I talked to said that:
1. There is no fix to be had, since it's not an issue and it was "designed that way".
2. There is no remedy to stop the rattling since it's not an issue (once again).
3. Replacements cannot be given for this issue since, well, it's not an issue. It's "normal" and within specifications.
I proceeded to ask why my 4S didn't have this rattle, but my 5s does. How am I to record video while walking, running, or just moving about in whatever way I please? The genius's response was simple: Don't. No one records video in such a manner, and if you do, it's your problem, not Apple's.
I would have replied back that I could do all of the above perfectly fine with my 4S, but I had enough and realized it wasn't going to get me anywhere. I just thanked him bitterly and left.
Back at home, though, I contacted Apple Support through chat. Alex talked and sympathized with me, stating that he suffered from the same issue, but that Apple claims that it is within specifications (and thus, not an issue/defect). He offered solutions, such as putting a case on that limits the movement of the power button, or even using tape.
So basically, Apple refuses to acknowledge this as an issue, especially since it's a widespread one. All that talk about having sophisticated manufacturing processes to pick out the best fitting parts for each phone is total malarky.
Such emphasis placed on just how much more improved the camera is on the 5s compared to previous iterations, yet such a obvious issue is overlooked, rendering the video camera completely useless.
Apple designed the iPhone 5s this way. Yep; designed it to rattle. It was all part of the plan. And no one, absolutely no one, should ever use a video camera while moving around, cause it's just not normal.
I'll just go back to my HTC One for the time being. Perhaps with the next iPhone, Apple will actually take us abnormal people into consideration.
For anyone stumbling upon this post (presumably from searching the web about this rattle noise), here's a suggestion: do NOT buy the 5s for its video camera capabilities. It is entirely useless, as you cannot record footage without even a slight rattle noise in the video.
I love Apple, but this is too much.
