Apple’s been making big claims about iOS 12 for a few months now, touting that even devices as old as the 2013-era iPhone 5S will be much faster. Historically, folks tend to notice a slowdown with every iOS update, but this latest one promised a change.

iOS 12 is now out, which means people can test whether all this is true or just marketing hype. Ars Technica tries to answer this question in a new article. The publication installed iOS 12 in the iPhone 5S, iPhone 6 Plus, and iPad Mini 2 and compared it to previous versions of iOS.

iOS 12 vs iOS 11 vs iOS 10

Each device had a gently used battery, so there weren’t any battery-specific slowdown issues. The first test measured how long an app takes to start and boot times. Safari, Camera, Settings, Mail, Messages, Calendar, Maps, and Notes were all launched one by one.

The iPhone 5S did very well on iOS 12 as compared to iOS 10.3.3, iOS 11, and iOS 11.4.1 all-in-all. The Settings app kicked into gear 26.1% faster, while the Camera app takes 16.2% less time compared to the previous OS. Apple even managed to shave off 2.39 seconds from the cold boot time between iOS 11.4.1 and iOS 12.

The iPhone 6 Plus performed similarly on iOS 12, becoming faster in general when compared to iOS 11.4.1 only. It jumped up by 21.7% when opening the Settings app and 18.3% in the Camera app. Boot time reduced by an impressive 13% from 25.49 seconds to 22.18 seconds.

The iPad Mini 2 is a bit of a disappointment compared to the iPhones. iOS 12 does show up to a 26.2% improvement in app launch times and a 14.5% decrease in cold boot time, but there’s no denying the fact that it takes too long to open an application in both iOS 11.4.1 and iOS 12.

Apple claims the keyboard is up to 50% faster as well, but the report didn’t notice a major difference in the Camera, Notes, or Safari app’s ability to load the keyboard. Still, at least it’s not any slower. You can download iOS 12 via Settings > General > Software Update on your iPhone/iPad or through iTunes on your Mac/PC.
