New versions of iOS do not reduce the performance of older iPhone – tested


There is an opinion that with each update of the iPhone operating system, which existed on our planet for longer than a year, they start to work more slowly. It is rumored that Apple could specifically do this by inciting users of its devices to purchase a new smartphone, because why change what works so well. The creators of Futuremark's synthetic performance test could verify whether this is so.

In order to find out whether Apple is artificially underestimating the performance of the old iPhone, Futuremark analyzed the data of more than 100,000 synthetic performance tests conducted during the last three years. This allowed to track changes in the test results of different models of the iPhone in the periods of work on iOS 9, iOS 10 and iOS 11.

Starts with the iPhone 5s. This model is the oldest smartphone that supports iOS 11. It was introduced in 2013, and this is the first iPhone with a 64-bit processor. As we already know, iOS 11 works only on 64-bit devices. Below you can see how the test results of the iPhone 5s changed using 3DMark Sling Shot Extreme Graphics.

Obviously, the CPU and GPU performance in the iPhone 5s did not change much with the upgrade to the new version of iOS. Exactly the same result was given by tests of tests of other iPhone models. If you believe them, the performance of the graphics accelerator in the iPhone 6 has even increased with the transition to iOS 11.

All this makes one seriously doubt that Apple could really artificially reduce the performance of its devices. Nevertheless, it is quite obvious that older devices are more difficult to cope with the functions and updated elements of the interface of the new OS. In addition, they have to work with new applications and new APIs. This can give a tangible difference in the speed of work.
