It was "battery management" of a degraded battery, with insufficient peak capacity, that was completely hidden from the user. Apple stores were refusing to replace the battery, even at the users cost, stating that it passed all tests.For the 1000th time we revisit this issue and the same nonsense. It’s not throttling it’s battery management. Every modern piece of hardware does it. But Apple did it and everyone freaks out. But the alternatives were worse - shutting the whole device down. But this electrical engineering is too complicated for users and too complicated for judges. All lawyers see is free money.
Yeah, I'd say that's worthy of "freaking out" over.
