Just got my Verizon 5s yesterday and have it updated. Not really seeing any issues just that it seems to drain battery a little faster than my updated 5c did. Maybe thats normal. I need to read more, I saw some posts about battery life I believe.
I had the same problem with battery drainage. It was suggested that I allow my battery to drain to 0% and then charge to 100% (did that a couple of times), when I followed this suggestion my battery life noticeably improved to where my battery like is now better than it was with iOS 8.0.2
