In Short

Just as expected, Samsung unveiled its Galaxy S8 and Galaxy S8+ on March 29 at an event in New York City.

The two phones, which are only differentiated by their screen size and battery capacity, come in at 5.8-inches and 6.2-inches with extra-tall 18.5:9 aspect ratio displays. That battery difference is pretty subtle: 3500mAh for the Galaxy S8+ and 3000mAh for the standard Galaxy S8.

Though the batteries haven't increased in size from the Galaxy S7 and S7 edge, the hope is that the improved efficiency of the new 10 nm processor inside will provide some help — that'll be the Qualcomm Snapdragon 835 or the Samsung Exynos 8895, depending on the region. The processor is backed up by 4GB of RAM, an increase to 64GB of storage, and of course a microSD card slot. Waterproofing and wireless charging are still here as well, plus a new USB-C port on the bottom. The rear camera is unchanged in terms of its 12MP sensor and f/1.7 lens, but will have improved processing thanks to new software and a new ISP (image signal processor).

The overall design for the phones is identical on both sizes, and is still shimmering glass and metal much like the previous generation. It's punctuated by the long edges of the displays curving subtly off the side, more so like the Galaxy Note 7 than the more dramatic Galaxy S7 edge — and to that point, there is no "edge" model here, as both phones sport the curves.

The displays have a new 18.5:9 aspect ratio with a QHD+ resolution, meaning they're extra tall while staying relatively narrow. Samsung has also moved to on-screen buttons and reduced bezel size dramatically in order to fit as much screen into the body as possible. That necessitated the movement of the fingerprint sensor to the back of the phones, where it sits somewhat-awkwardly next to the camera lens. Iris scanning makes its return in a new-and-improved version from the Note 7 to hopefully pick up the slack.

Samsung is trying to drive a narrative that we've moved beyond specs (and you can definitely argue that we have), but the enthusiasts will always want to know the details of what's powering the latest phones. You get just about everything in here that you'd expect — basically, think of a Galaxy S7, and bump up a few areas to 2017 standards. That means you're getting 4GB of RAM, 64GB storage with an SD card slot, QHD+ resolution AMOLED displays, USB-C, fast charging, wireless charging and the latest Qualcomm or Samsung processor inside.

As for the two different models, the Galaxy S8 and S8+ are identical internally aside from the batteries and of course screen sizes.
