According to MacRumors, Apple recently updated its list of "vintage products", including the iPhone 6 Plus, which has been on sale for more than 5 years. The iPhone 6 Plus was originally released in September 2014, but Apple officially relaunched the line again in 2017, so it still counts as 5 years.
The iPhone 6 series was also the first device to support Apple Pay, and the multi-size form factor for the series models began there. In 2019, iOS 13 stopped supporting the iPhone 6 series. As a former nail household product, this series finally retired from the stage of history.
