While I understand where you are coming from, the iPhone 4 was announced in 2010[1].

I believe a more apt comparison would be my current situation with an iPhone 6 which came out in 2014[2]. It works perfectly fine, albeit with a new battery. I do not plan on upgrading to any iPhone past the 6 unless the headphone jack comes back (my major personal gripe).
