Some users believe that Apple deliberately slows down older iPhones with every release of the new version of iOS. How much is this truth?

When we decide to purchase a particular device, we assume it will work efficiently for a long time. We're releasing new releases of the operating system that should bring new innovations and cost-effective improvements to the smartphone's performance. Some people, however, say that often happens differently. They say so. iPhone users who experience slower performance on older smartphones with every new version of the system. Futuremark is a benchmarking company that has decided to check how many of the above statements are right for you. It compared the performance of smartphones on the basis of 100,000 metrics from April 2016 to September 2017. Three versions of iOS have been taken into account: 9, 10, and 11 have been tested. IPhone 5S, 6, 6S and 7 have been tested . The first is the oldest iPhone with a 64-bit processor. The test uses the 3DMark Sling Shot Extreme and Physics Edition. The data collected indicates that the GPU and CPU performance of the "Fridays" is at the same level.

Interestingly, the iOS 6 "GPU" has even outperformed. In the case of the CPU, you see a slow, slight decrease in performance. In the case of iPhone 6S and 7, the situation is very similar and there are no significant changes. So what are the conclusions of this study? According to Futuremark, Apple supports older devices and takes care of their smooth running and performance over the next version of the system. Thus, there is no mention of deliberate slowdowns.

In my opinion this is true, but the problem lies in a slightly different matter. The same goes for Futuremark in the final conclusions. With each system, we always have more features, security, graphics, or other animations that affect hardware resources. We also have applications and their data that we are constantly gathering, so their processing by the system needs more time / resources. In addition, developers may not optimize their applications for older iPhones. In that case, the slower performance of the smartphones is too much. Source: Futuremark
