NOTE: This is not a thread complaining about the iPhone 6 like the ones I've seen. I love my iPhone 6 and am very happy, but had one observation. I came from an iPhone 4S with the A5 chip. I never updated to iOS 8, but even on iOS 7 the phone still worked well. Yes, there was some UI lag here and there and some apps (Music) took a while to open and refresh, but still. Maybe I built up the difference in my mind too much, but according to Apple the A8 has 5X the CPU and 6X the GPU power as the A5, but there was never a moment where I thought "wow, this phone is fast" like I did when I got upgraded from an iPod Touch 4G to the iPhone 4S. The UI is definitely smoother and some apps like Music and Setting open instantly with little lag, but it still wasn't the jump I was anticipating. Most apps open in relative the same time. Anyone else feel this way? Economies of scale I suppose. I suspect it's just me. But I do love my iPhone 6 and the network speed is orders of magnitude better. ------- Update: I have not attempted gaming on this phone which probably shows off the difference more. My experience is just general navigation and app usage.
