Have another look at your numbers, you have assumed that there are only 100 repair shops in the word. I would imagine this number is much higher (a google search for 'iphone micro soldering repair shop' gives 473k results)
Right. He was underestimating to demonstrate that even a very small number of shops and iPhones/week would yield a large amount.
But also we should take into context how many iPhone 6 and 6+s have been sold. The first article on a Google search comes up with Wired who is discussing numbers from Oct-Dec of last year and in that time Apple sold 75 MILLION iPhones.
And I think the iPhone 6 model has only been out for a year or two, right? So even if we quadrupled the defect number per year, we'd still fall quite short of even the recent Samsung recall.
Please keep in mind I'm not saying it's not a problem, just trying to help put numbers into perspective.
Googling for "iphone witch doctor repair shop" gives 263k results. So there are roughly half as many iPhone witch doctor repair shops as iPhone micro soldering repair shops?
how about a google for "iphone repair shop" (with double quotes) gives 155k results. Eyeballing a few pages of results seems like the vast majority of results are for real iPhone repair shops. From this I would confidently estimate that there are > 15k and < 1.5m iPhone repair shows worldwide.
Read my comment again, I was positing perhaps the author of the article talked to 100 repair shops. Yes, there are certainly more repair shops than that worldwide. I was just drawing a line from what data the article has to what we could guess from it reasonably, each step trying to give the benefit of the doubt to the problem being as widespread as we can infer from the article.
Number of google results for a keyword doesn't really give a good indication of how many stores there are for that thing in the world. 473,000 repair shops would be 1,000 for every Apple Store. I'm sure there's a lot but that seems a bit high.
Regardless, I didn't attempt to draw the line through number of iPhone repair shops in the world because we have no evidence whether all repair shops in the world are seeing this problem, only the ones the author of the article talked to.
There's no particular reason to think that the repair shops which the author of the article chose to speak to are special in any way, so it's reasonable to assume that all the other repair shops are seeing similar numbers. It's definitely not reasonable to assume that the only iPhones that are failing are the ones served by that handful of repair shops.
> it's reasonable to assume that all the other repair shops are seeing similar numbers.
I don't know, it depends on how many the author actually spoke to and how he came by them. If he found them because he saw them all talking about this problem, that's not a statistically reliable means of sampling repair shops. His selection was biased and driven by the issue.
