Many users have asked us before installing the new update of iOS, how the new version of the operating system will run on older devices. Now this question can be answered, and you can even see results of the comparison of speed of iOS 10.3 beta 2 and iOS 10.2.1.
Below are relevant videos by blogger iAppleBytes, who launched a new version of the iOS on the iPhone 5, iPhone 5S, iPhone 6 and iPhone 6s.
Curiously that iOS 10.3 was faster on all devices – not excluded that this was achieved through the use of APFS file system. Applications are opening faster bright, and indeed the system interface has become much more active.
So far, iOS 10.3 is available in beta status, but it is clear that the release version will be just as good. That means owners of older iPhones (yes, yes, and the iPhone 6s, too) will be able to upgrade without any problems.
