Right after its ‘Gather Round’ event earlier this week, Apple released the Golden Master build of iOS 12 to developers. If there are no major bugs discovered, the iOS 12 GM build would be seeded to the public as the first public release of the OS. With iOS 12 promising massive performance improvements, let’s see how iOS 12 GM compares to iOS 11.4 in speed tests conducted on older iPhones.
On older iPhones like the iPhone 7 and iPhone 6s, the iOS 12 GM build boots faster than iOS 11.4.1 — the last stable release of iOS 11. Even day-to-day tasks like opening apps and navigating around the UI seems to be faster on the iPhone 7 and iPhone 6s running iOS 12 Golden Master. The difference might not seem like a lot from the videos but in real life, it would help restore the feeling of the UI being silky smooth and stutter free on these devices.
When compared to the first beta of iOS 12, the Golden Master build boots significantly faster. It is also slightly faster in opening apps, with system animations feeling just a wee bit smoother.
The faster app loading times in iOS 12 along will have a major usability impact as it will create an impression of older iPhones running faster post installing the latest iOS release.
It is amazing to see just how much Apple has been able to improve the performance of its older devices by simply rolling out a software update. This shows that there’s always room for the company to optimize the performance of its devices and their tight integration with iOS can also be further improved.
Making things more interesting, there’s also a speed test of iOS 12 GM vs iOS 9.3 and iOS 10.3. In both speeds tests, the iPhone 6s was faster in loading certain apps on older versions of the iOS when compared to iOS 12. However, the latter feels more responsive to navigate around unlike iOS 9.3 and iOS 10.3 where you will see some stutters and dropped frames every once in a while.
The first public build of iOS 12 is slated to be released to the public on September 17 alongside watchOS 5.
