The results were as follows: iOS 12 performed better on all tested devices. This is especially noticeable when running regular apps. The results of the performance test were within a static error. Download speed operating system has also been greatly improved, but not on all devices. For some reason the iPhone 7 on iOS 12 is loaded a little slower than on iOS 11.
