Faster? No, not really noticeable. We also don't have any apps utilizing the new hardware yet, so this is a wash.
The camera is nicer, mostly better at reducing the blur (IME). I take pics mostly of our dogs, and they move a lot. This camera does a better job with that. I don't do much in terms of using flash, so I haven;t noticed either way there.
Battery life is slightly better, maybe. I can't tell. Maybe wishful thinking on my part, or maybe slightly better. Nothing to write home about, honestly. If you were fine with the 5, you'll be fine with this. If you struggled with your battery on the 5, the S likely won't be much better.
best addition is the fingerprint sensor, from an early adopter point of view. Convenient. Saves time. Does what it was meant to do.
