Benchmarking company Futuremark recently set out to debunk long-running speculation that Apple intentionally slows down older iPhones when it releases new software updates as a way to encourage its customers to buy new devices.
Since 2016, Futuremark has collected over 100,000 benchmark results for seven different iPhone models running iOS 9, iOS 10 and iOS 11. First and foremost, by gathering the results of the 3DMark Sling Shot Extreme Graphics test run on the iPhone 5s from April 2016 to September 2017, Futuremark was able to determine that there had been virtually no change in GPU performance, regardless of which version of iOS was installed:
The same was true of the 3DMark Sling Shot Extreme Physics test conducted on the iPhone 5s. Once again, CPU performance fluctuated slightly over time, but didn’t appear to have any correlation with the iOS version:
Futuremark ran the same tests on the iPhone 6, the iPhone 6s and the iPhone 7. Time and time again, the results were the same. In other words, there is no grand conspiracy, and Apple isn’t doing anything to intentionally kill your iPhone battery or slow it to a crawl. Like any other electronic device, your phone will age and will undoubtedly feel slow in comparison to the next big thing, but the planned obsolescence myth is just that: a myth.
