Just for fun, I attempted to calculate what year each active iPhone would stop getting updates
Obviously I have no way of knowing if this is true or not, but I thought this would be fun to calculate based off the pattern of updates each phone has gotten so far. Essentially, each S and the phone after it received an additional year of upgrades from the previous cycle, so I thought it’d be interesting to estimate. This is assuming the 5s’s last update is iOS 12, of course.
The first year is when it was released. The second year is what year it would stop getting iOS updates/you would need to upgrade the new phone.
* 5s – 2013-2019
* 6 – 2014-2020
* 6s/SE – 2015-2022
* 7 – 2016-2023
* 8/X – 2017-2025
* Xs/XR – 2018-2026
Yes, I probably have too much time on my hands. Anyway, like I said, this is just for fun and in no way official.
