TechCrunch’s Matthew Panzarino has written my favorite iPhone 6s review yet. He goes into detail on performance and camera improvements, but he also focuses on the productivity aspect of 3D Touch and why iOS 7’s design helped bring the feature to life.

This is one of the big things that 3D Touch does, it eases the fear of handling actionable items. It allows you to retain your context while adding something to your calendar, peeking at an email or sneaking a look at a link to see if you really want to read it.

Pressing lightly to ‘peek’ and pushing hard to ‘pop’ it into existence provides an escape hatch that eases your mind, and a new iOS 9 affordance injects a ‘back’ button at the top left corner of any screen you jump to. iOS 9’s new task manager, accessed by a firm press on the edge of the screen (or the standard double-tap of the home button) is also arranged in a much more contextually rich card format — a time-line of your jumping around through apps.

It’s not hard to imagine how apps will take advantage of 3D Touch, and Matthew gets it.

From Joanna Stern’s iPhone 6s review for the WSJ:

Let’s get this out of the way first. The No. 1 thing people want in a smartphone is better battery life. And the iPhone 6s doesn’t deliver that.

And:

Still, there is no battery improvement over last year’s iPhone 6 models. In our grueling test; which loops a series of websites with brightness set at around 65%, I found the 6s and 6s Plus get no more—but also no less—battery life than their predecessors. (iOS 9 itself adds an hour of savings to the iPhone 6, and has Low Power Mode.) Strangely, although Apple says that the 6s Plus gets hours more battery life than the 6s, repeated testing on multiple devices reveals a slimmer difference. In a Web surfing test, the 6s on average lasted for 8 hours, while the 6s Plus went 20 minutes longer. In a video playback test, the difference was an hour.

This is a common theme in reviews I’ve read this morning. Given that Apple had to ship a smaller battery to make room for new components, the fact that the 6s is still getting the same performance on a more powerful hardware suggests that iOS 9’s optimization technologies are working.

The iPhone 6s review embargo lifted this morning. As usual, the first review of a new iPhone I read is Jim Dalrymple’s:

Peek and Pop work all over the place on iPhone. In Apple Music, you can use it to view albums and playlists; you can view Messages and texts; You can set calendar events, view flight info, view images and videos and all kinds of other things.

3D Touch is one of the handiest features that I’ve seen from Apple in a long time. It’s not just that it’s cool, it actually saves me time. It’s a new way to navigate the iPhone that’s quick, easy, and efficient.
