- $200 no questions asked buy-back - Better camera - Larger screen in a just about the same size form factor
I expect to have this phone for ~4 years with probably a battery refresh in ~2ish.
I went 4S -> 6S -> XS. I hadn't upgraded an iPhone in years, Apple has made the process extremely slick and painless. I was seriously impressed at picking up the new phone and being "good to go" in ~45 min when my apps downloaded.
I'm sure I'm an outlier
