Preview at WWDC likely in June, followed by September launch.
iPhone 6s Bests Samsung's New Galaxy Note 7 in App Speed Test
Spec wise, the Galaxy Note 7 seems to best the dual-core A9 processor and the 2GB RAM of the iPhone 6s, but based on a new speed test, it's clear raw hardware can't quite match superior hardware and software integration when it comes to real world usage.
In the performance comparison in which the two phones simultaneously launched the same apps, Samsung's Galaxy Note 7 was thoroughly defeated by the iPhone 6s, despite the Note 7's cutting edge hardware and the fact that it's a year newer than Apple's latest iPhone.
The iPhone was able to launch apps in succession at a much faster rate than the Galaxy Note 7, launching 14 apps (including rendering a video) in one minute and 21 seconds and eventually lapping the Galaxy Note 7, which took two minutes and four seconds to complete the same tasks. The iPhone was able to cycle through two laps of the app test in one minute and 51 seconds, while the Note 7 took two minutes and 49 seconds, almost a full minute longer.
This is just a single test that compares an unusual usage scenario, but it does suggest Apple's efforts to deeply integrate hardware and software give the iPhone some significant benefits compared to even the latest Android devices.
Apple will be announcing a new iPhone 7 and iPhone 7 Plus in the near future with improved hardware that includes a faster, more efficient A10 processor and perhaps more RAM, at least in the larger device. The new phones are expected to debut in early September with a launch coming later in the month.
