Gee, I wonder if this is really deliberate/by design. Apple and Samsung seem to be legitimately committed to delivering high performance products. And it's great that they're providing software updates -- imagine the flip side, that would be planned obsolescence for sure. I've worked at places that do performance regression tests and there's usually some small threshold that's tolerated (<1% or something, let's say). The cumulative effect of these might be enough to have significant impact. But another problem is that they're probably doing more target testing on the new designs than the old designs and they might not notice/care enough about the impact of features on old targets' performance. If they're not maintaining independent software branches for the ease of delivering updates, then they risk introducing performance regressions on old targets.
