This is not surprising and expected for refurbed units from any company.... but there are people who claim that there's no difference between Apple new and refurb. Some even say that refurbs are better because of the additional "rework and testing" that takes place.
Well, it is somewhat surprising for me, because re-using the logic boards for iOS devices seems like a bad idea. I've seen how a few electronics companies do refurbs for portable electronics, and generally it is the case to just swap logic boards if there's signs of damage rather than trying to repair the board itself. Apple has a lot more pricy bits on the logic board, which makes it more expensive, but I'm now curious exactly what their policy is on logic board repairs for iPads and iPhones.
But refurbs do actually go through testing (in order to sell them as refurbished), while new are randomly sampled for testing to catch batch failures, rather than trying to find individual units that are bad. That said, that sort of testing won't catch issues in the repair like this woman encountered, since the repair is "good" until a drop damages the repair. In general, I consider the risks you play with new or refurb to be about equal. Similar failure rates with different modes of failure. Unless there's something specifically bad about a particular company's repair process.
And you can't assume that they're different either.
Agreed. I wouldn't expect them to have two different repair processes for refurbs and swaps, but the techs doing the work may be different. The question I have here is if this particular device's refurbishment represents:
1) A mistake on the part of the tech doing the work, and possibly a second tech that did the logic board repair. Not recognizing water damage, etc.
2) Apple policy on repairs for water damaged boards. Repairing water damaged boards if the damage is "limited", for some subjective definition of "limited".
