Apple's QC has gone down a lot, and allegedly they are trying to do something about it.
It's ridiculous that people insist Apple can do no wrong. If you're mass producing a device you'll always get some duds no matter who you are and some of these products are bound to slip thru any QC process.
I have yet to see a defective one.
If nothing else is wrong with the phone, fix the loose battery yourself. All you need is a pentalobe screwdriver, some tape, and about 15 minutes.
I can tell you from experience that when the ip5 came out initially it was bad dents scratches etc. Now understand not everyone experienced this, but quite a few did including my self. I recently picked up a new black one about a month ago and I can tell you now QC is far better !!!! Last two phones I have had have been physically perfect, only issue I'm having is with software on my end.
