Tests performed by the ArsTechnica service confirm that the latest iOS improves the performance of old Apple devices. Tests have been performed on, among other devices, iPhones 5 and 6S Plus and an iPad 2 Mini. Results clearly show an increase in performance when based to iOS 10.3.3 and older Apple operating systems. For example, Safari browser takes up to 2 seconds to start on older operating systems, while it only takes 1.15 second on iOS 12. Camera takes similiarly shorter time to turn on with the iOS 12 than with its older versions. These are not large differences, but certainly enough to make Apple fans happy.
