iPhone 5S it is currently the oldest Apple phone that still has support in the latest versions of the iOS operating system, the phone being released in 2013. Performance can become the biggest problem for such an old phone, and below do you have a comparison between iOS 7, iOS 8, iOS 9, iOS 10 and iOS 11 on the iPhone 5S.
iPhone 5S has the best performance for starting on iOS 7, as expected, and of course in iOS 11 it has the worst performance, the differences being quite large. For operating system usage, animations run in iOS 11 much better than in iOS 10 and iOS 9, sometimes almost as well as in iOS 7, which is surprising.
iPhone 5S: Performance comparison on iOS 6 – iOS 11
In the case of using applications, iOS 7 remains without question the fastest system of all, and iOS 11 does not perform as well, mainly because of the longer animations. Things are not better for the use of Siri either, although here iOS 7 did not win the cause in any test, but neither did iOS 11 do as well as in the previous ones.
In the case of third-party applications, the older the operating system is, the faster the applications load, so that in iOS 11 they load the hardest of all. Even in performance tests, the situation is not better, iOS 7 offering the best performance, and iOS 11 the worst, and now it's interesting to see what iOS 12, which should run on this model, will offer.
