iOS 12 beta speed test: How fast is it on older phones?Apple claims iOS 12 offers significant performance improvements over iOS 11 -- so we tested it on the elderly iPhone 5S.
[BLANK_AUDIO] Apple claims iOS 12 offers significant performance improvements over iOS11, especially on older devices. You'll see that apps launch up to 40% faster. The keyboard can come up to 50% faster and you can slide to take a photo at upto 70% faster. Those tests from the wwwdcknote were from an iPhone's 6 plus. But we are gonna see how it performance on the oldest supported phone that runs iOS 12 the iPhone 5S. We have two phones, both factory reset and we've closed all the apps. One is running iOS 11.4 and the other is running the iOS 12 public beta. This is not a scientific test and given this is beta software, performance may change between now and the final release of iOS 12 in the fall. Let's start by launching some apps. For some, like Mail and Safari, there is a difference in load time. [BLANK_AUDIO] [MUSIC] But others like Maps and Weather is hardly noticeable. [MUSIC] Opening the keyboard for messages is the full second faster on iOS 12. And launching the camera from the lock screen is also faster with the camera focused and ready to go about half a second before iOS 11. Apple claims bringing up the share shape is two times faster when the system is under load and it is significantly faster on iOS 12 as you can see here. [MUSIC] [BLANK_AUDIO] As for Siri, she completes your command about half a second faster on iOS 12, but for startup time, iOS 11 pulls ahead with a good nine seconds on the newer system. So there is a big improvement in some areas for the older phone running iOS 12, but it's not a clear win in every category. And as always, performance is subject to change in the final release.
