The video, which was uploaded by Apple enthusiasts, EverythingApplePro, shows a speed comparison between iPhones that are a generation older than the other. In this case, the phones in questions are the iPhone 11 Pro, and iPhone XS, iPhone X. The speed tests are conducted twice; once with the app being opened for the first time, followed by the app being reopened after the initial run. Surprisingly, the iPhone XS was able to keep up with the iPhone 11 Pro app launch time with an only one-second difference when the lap time was timed. During the second run, the iPhone XS was able to initialise apps a lot quicker, eventually beating its successor to the finish line nearly 30 seconds faster. In this test, the iPhone X clearly showed its age as the phone does take a while to fully open an app to its main menu. The most noticeable delays when launching apps were between Fornite and Minecraft. In this portion of the test, both the iPhone XS and iPhone 11 Pro are neck to neck in loading up both games. On the other hand, the tester notes that the iPhone 11 Pro has a heat issue during usage, and that issue is not limited during the tests only. There are also mentions of strange sounds coming out of the display at random times.
One reason for this, as pointed out, is probably because some of the developers have not optimised their titles to take full advantage of the A13 Bionic chipset inside the iPhone 11 Pro. On that note, the tester believes that the next version of iOS should bring about some optimisations for the iPhone 11 Pro, which in turn means that he will be re-running the same test on all three phones in the future.
