Hi folks, Decided to take the plunge and return to an iPhone today after a decent run with Android. Gone for a 5S. I have one reservation though. I recall when I had my iPhone 5 and iOS 7 came out, the performance was pretty janky. Everything felt a bit stuttery. I missed iOS 6 in fact. Could you confirm whether the 5S works better in iOS 8? Be pretty gutted getting the phone to find iOS 8 giving it a beating.
