And Apple can't completely dodge accusations of planned obsolescence given that it does make the iPhone's battery hard to replace and uses special screws that make it more difficult to fix, although iFixit's repairability score for the iPhone shows that it's no worse than many Android phones.
The performance-tracking experts crunched the numbers in their database, based on real-world tests, comparing the iPhone 5S across iOS 9, iOS 10, and iOS 11 stretching back to April 2016. The latest iteration of this claim that Apple is slowing down your iPhone surfaced in the form of an online article that was shared 270,000 times before it was taken down.
Futuremark looked at the performances of the central processing unit - commonly called as the brains of the iPhone - and the graphics processing unit, which focuses on processing graphics-related calculations. There has been a small fall in CPU performance, but not enough to be noticeable, according to Futuremark. The figures for iOS 9, 10, and 11 are nearly as steady as a rock for two years.
Processor performance was equally consistent leading Futuremark to conclude that "it is clear that iOS updates have not had a significant effect on performance".
The numbers don't lie, folks. That resulted in several bouts of battery drain issues, but it also slowed down the performance of the app. Apps that aren't optimized for your device could run slower.
One of the biggest myths about iPhone performance has finally been busted. The results are submitted from iPhone owners who've installed its 3DMark benchmarking app. However, many people have found some issues and lack of other important features like 3D Touch App Switcher on the original iOS 11 update which is now coming to your device with the next iOS 11 update.
