New iOS releases usually come out with new phone launches. The SoC had only recently gotten powerful enough that it could spike past the instantaneous capacity of the battery. We know that throttling is real, and it has been well documented and was undoubtedly a communications failure of Apple, however it's remarkable how frequently throughout this discussion people are giving vague anecdotes about performance that should be easily verified and proven. Sometimes, though, our old phones feel slow only in a relative sense. When you experience a newer device it does often suddenly make your old device that once seemed silky smooth and magically performant now look like a piece of crap. That's just the march of technology.
