The iPhone 6 (2014) also got iOS 12.5.7 January of this year.

The iPhone 6s (2015) and iPhone 7 (2016) and iPhone 8 and 10 (2017) got its last update September of this year.

All of the iPhones released after that runs the latest operating system.

The iPads of the same generation get the same upgrades.

The 5s was the first 64 bit iPhone.
