If all you care about is a speedy operating system, and iOS 8.4.1 has everything you need already, is it worth upgrading to the new iOS 9 update? In the video below, you can find out exactly how much of a difference iOS 9 makes in performance on the iPhone 6, iPhone 5s, iPhone 5, and iPhone 4s.
Published by EverythingApplePro on YouTube, the 8-minute video below puts iOS 9 — the public release that was rolled out on Wednesday — up against iOS 8.4.1 in a series of everyday tests to find out which is faster at starting up, browsing the web, launching apps, and more.
iOS 9 appears to follow the traditional pattern of iOS updates in that it works incredibly well on more recent hardware, but not so well on older devices. It’s slower to start up than iOS 8.4.1 on the iPhone 4s, for instance, but faster on iPhone 5, iPhone 5s, and iPhone 6.
However, when it comes to loading apps, iOS 8.4.1 is snappier on almost all of the iPhones tested. It also results in slightly better GeekBench scores in most cases. There is a definite speed improvement in Wi-Fi and browsing speed in iOS 9, however.
Whether the upgrade is worth if for you, then, depends on what’s more important — loading apps, startup times, web browsing speeds, etc. However, even in the situations where iOS 9 is slower, it’s not significantly slower than its predecessor.
With that in mind, we firmly believes iOS 9’s new features are well worth the small sacrifice.
