I like iOS 8.1/iOS 8 but I have been experiencing more crashes. Hopefully next update might fix these.
That's awful
Did you try resetting all settings after updating to 8.1?
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
