Tomorrow, Apple will release iOS 11, the latest installment of its mobile operating system. Millions of Apple users will be eagerly waiting to get their devices up to speed, yet some of them are about to be disappointed.
As the technology housed within iPhones and iPads has advanced significantly over the years, so have the demands of the software running them. As a consequence, Apple has to leave some users behind every year. This year it's the iPhone 5 and the fourth generation iPad (both released in 2012) that didn't make the cut.
As our chart illustrates, the longevity of iPhones has improved over the years. While the first and second generation of iPhones only received two new iOS versions before being left behind, Apple extended the iPhone’s lifetime from four years for the iPhone 3GS and iPhone 4 to five years for the iPhone 4s and iPhone 5, the victim of this year's iOS release.
