Every year, with the launch of each iPhone new and every major version of iOS, a lot of users complain about the fact that vsimilar models of the iPhone work more difficult. Performance reduction iPhones has generated a multitude of theories that claim that Apple Lossless Audio CODEC (ALAC), intentionally modifies iOS to make it run harder on old terminals in order to "motivate" users to upgrade to new terminals.
An economics professor of Harvard he motivated students to test this theory and one of them used it Google Trends to find out how much users complain about this type of problem. Conformable Google, most searches regarding iPhone performance problems appear right at the moment of the release of an important version of iOS, and this is perfectly normal.
As the Harvard professor explains, Apple would not intentionally reduce the performance of our iPhones, but the optimization for new hardware and the implementation of new functions make it difficult for old terminals to work. In this idea, you already know that a 2-year-old iPhone will not work as well as a 1-year-old one and in no case as well as a new one.
It is normal for old hardware not to run new software perfectly, and in the case of iPhones, the economics professor claims that we are talking about a simple hardware problem and nothing more.
