I own iPhone 5, which is not getting iOS updates anymore. Still works ok though, but the main issue I have with that design is it gets dust on the camera lenses inside the phone case (I don't use extra case). I have replaced it twice in the Apple Store because of the dust, but the last time my 3-month warranty expired before I got sufficient amount of it. Then I bought a repair kit to clean it but managed to crack the glass opening the case, not much but annoying. And in a few weeks there was dust on the lenses again. So I decided to switch to SE and went to Apple Store to have a look on it and guess what, there was dust on the SE lenses right in the store! Well, it's time to switch anyway, so maybe putting some plugs on headphone and lightning jacks would help. Buying Apple Care warranty is actually a good idea for this case, because you can get a new phone every 3-4 months so you don't need to worry about your battery health.
