So every year we read about how the previous generation gets slow with the new iOS and the new software is so much "snappier" on the new faster iPhones. But the question popped into my head, what if we put the phones on the software that came with them and then measured speed of things everyone does regularly? Such as opening and closing apps, swiping around the home screen, loading websites in safari, etc. This could look like someone doing a bunch on things with a iPhone 6 on iOS 8.0 (and perhaps also testing with 8.4.1) and a 6S on iOS 9.0? FWIW, I'm not questioning the benchmarks and everything that show the newest phone is faster. I'm more interested in seeing if the phones are that separate in daily tasks with software that came with them. Or I could be off my rocker/computer chair here. Thanks!
