New Speed Test Compares iOS 10 Beta 4 With iOS 9.3.3 on iPhone

iOS 9.3.3 vs. iOS 10 speed test

Apple rolled out its fourth iOS 10 beta to registered developers on Monday, and as usual, its release promised bug fixes and performance improvements. But do those changes make iOS 10 any faster than iOS 9.3.3 — Apple last public release? Find out in the tests below.

As it does with every iOS update Apple rolls out, the iAppleBytes channel on YouTube has put iOS 10 beta 4 through its paces on the latest iPhones to see how it compares to iOS 9.3.3, which is the most recent public release that the vast majority will be running.

On iPhone 6s, as has been the case with previous iOS 10 betas, not much has changed in terms of performance. iOS 10 continues to boot up every so slightly faster, but when it comes to launching apps, browsing the web, and multitasking, there’s nothing in it.

It’s a similar story on the iPhone 6; boot up time has been reduced slightly, but general performance throughout the rest of the operating system remains the same. Of course, that’s not exactly a bad thing given iOS 9.3.3 was already very snappy.

On iPhone 5s, iOS 9.3.3 actually boots up faster than iOS 10 beta 4. It’s also slightly faster at launching some apps, including Messages, Weather, Camera, and Maps. There’s not a great difference, but it’s certainly noticeable.

Interestingly, on the iPhone 5 with even older internals, iOS 10 beta 4 boots up faster than iOS 9.3.3, so it’s unclear why that’s not the case on the iPhone 5s. iOS 10 is also slightly faster at launching certain apps and loading webpages in Safari.

iOS 10 won’t be available to all until this fall, so bear in mind that performance could still change before then. As things stand, however, it looks like this is shaping up to be an excellent upgrade — even for those with older iPhones.
