Apple has seen fit to release beta 12 of its upcoming iOS 12 operating system yesterday. While the company’s big ‘Gather round’ event is scheduled to take place on September 12, we presume the final build of iOS 12 will be available to users on the 19th. iOS 12 beta 12 fixes a major issue in beta 11 that prompted users to update from iOS 12 beta. However, it’s never to early to ask whether the new beta enhances performance as well. Well, a new speed test video has emerged that sheds light on the matter and how it compares to the current iOS 11.4.1.

iOS 12 beta 12 is probably the last beta that we will see before the final version arrives. So it would definitely be good to see how it stacks up against the current iOS 11.4.1. The previous beta versions showed improved performance on older iPhone models as well as new ones. Let’s see what the new beta has to offer on different iPhone models.
