I'm still happy with my 5S, but I did have to drop out-of-warranty money on a replacement battery. It was $80 at a third party shop, but would have been the standard 70% of initial retail price if I'd gone to Apple, i.e. ~$300. For a battery. And I would have needed an appointment to have it looked at.
Overall, I dislike Apple business model more, and their quality has been dropping. My Apple TV shipped with a dysfunctioning remote, requiring replacement.
Because I buy new hardware so infrequently, I'm not their target demographic. Kind of locked in at this point. :'(
