A big learning experience for me has also been that you shouldn't ever update an iPhone. Whatever version of iOS you got out of the factory, stick to it, because developers just don't give a fuck about performance. Between iOS updates, performance considerations aren't made for older models at all. Newer iOS versions are developed against higher end models. I don't give a fuck what the compatibility charts say, of course Apple's iOS team ensures that it works, that doesn't mean it works _well_. And it definitely doesn't mean it was intentionally designed to work against that model whatsoever. As a reminder, iPhone 6's original iOS version was 8. We're coming up on 12.
