iOS 11.1 and iOS 10.3.3 pass today a performance test on iPhone 5S, iPhone 6 and iPhone 6S to show us how the operating system works. As you can see, right from the start, the differences in performance are huge between the two operating systems, iOS 11.1 being much slower in almost everything done on the iPhone 5S, Apple seriously slowing down this phone.
iOS 11.1 and iOS 10.3.3 do not perform so differently as we look at the newer phones, but in the case of the iPhone 5S the difference between the phones is huge. to be completely honest, I didn't expect iOS 11.1 to run so hard on the iPhone 5S compared to iOS 10.3.3, but in the end Apple managed to slow down its old phone models, which still sell them
