There are no magical batteries that can supply the same peak current after two years' worth of charge cycles as on day one. There was no manufacturing defect in the batteries. The batteries were only 'defective' in the sense that their performance had reduced as the result of a completely normal aging process. The same thing happens to the batteries in all other phones. The only differences lie in how phones deal with this in software. As the raw physical performance of the battery degrades, this always involves some kind of compromise. Some people didn't like the compromise Apple chose and how they chose (not) to communicate it. But that's not a debate I'm trying to get into here.

It's quite different. A fine is something you'd get for violating some kind of regulation. This is a lawsuit that Apple settled.
