The Good The Samsung Galaxy S6 Edge's wraparound screen transforms an already great phone into Samsung's best-looking handset. Ever.

The Bad That supercool design comes with a big price tag, and the screen doesn't deliver any real killer apps. Like the regular S6, the Edge doesn't support swappable batteries or expandable storage.

The Bottom Line Samsung's striking, high-end Galaxy S6 Edge has the beauty, brains and brawn to take down the iPhone 6 and all the Android competition.

Editors' note (March 28, 2017): Samsung has unveiled the Galaxy S8 and Galaxy S8 Plus, the follow ups to 2016's excellent Galaxy S7 and S7 Edge. Priced at $750 (£689 and AU$1,199), the Galaxy S8 features a beautifully curved 5.8-inch screen with an ultra-narrow bezel; facial recognition as an alternative way to unlock the phone; and Samsung's nascent Bixby voice assistant. The S8 Plus costs a bit more -- $850, £779 or AU$1349 -- and comes equipped with a larger body and battery, but is otherwise identical.

Samsung has instituted an eight-point battery test on its new phones in an effort to reassure customers that it has addressed the issues that plagued its exploding Note 7 last year. To see how the Galaxy S8 and S8 Edge stack up against their predecessors, check out CNET's side-by-side comparison.

The original Samsung Galaxy S6 Edge review, published in April 2015 and updated since then, follows.

When the Galaxy S6 and 6S Edge debuted in the Spring of 2015, they represented a dramatic departure for Samsung. Gone was the utilitarian plastic build of every Galaxy S past; in its place, glass and aluminum alloy, and, in the case of the S6 Edge, a uniquely curved screen. CNET designated the Galaxy S6 "first great smartphone of 2015," awarding it an Editor's Choice. The Galaxy S6 Edge is an even higher-end, "designer" version of the S6 -- and you'll pay a premium for it.

The Galaxy S6 Edge's innovative, rounded-side display has earned a reputation as one of the best screens on a smartphone. And though the S6 and S6 Edge are close siblings with similar specs -- attractive aesthetics, first class components, and a few features (like wireless charging support) that cannot be found on any iPhone -- the S6 Edge certainly boasts the more premium look and feel. That noted, in the US, the S6 Edge costs $100 more than the S6 on contract, and about $100 to $130 more off-contract, with $100 bumps for each storage size. Given their nearly identical specs, the Galaxy S6 remains the better value.

In March 2016, Samsung introduced newer versions of its flagship Galaxy, the S7 and S7 Edge, at Mobile World Congress in Barcelona. While it has many of the same specs as the S7 -- a 12-megapixel camera, water resistance, a Qualcomm Snapdragon 820 processor, and a microSD slot -- the S7 Edge has a larger, 5.5-inch screen versus the S7's 5.1-incher. Also noteworthy is the S7 Edge's 3,600mAh battery -- rated for longer run time that the S7, the Edge 6+ and even the Galaxy Note 5, which is a real marathon runner.

If you already own an S6 Edge or even a newer S6 Edge+, the upgrade to an S7 or S7 Edge may not be worth it. That noted, the Galaxy S6 and S6 Edge remain affordable, competent, full-featured Samsung phones and represent some of the best values in Samsung's lineup.

Editors' note: This review has been updated extensively since its original publication on March 26, with additions including battery testing results and additional comparisons to the standard Galaxy S6. Ratings have also been added.

The S6 Edge: Like the S6, in a far prettier package

Releasing multiple variants of its Galaxy phones is old hat with Samsung. But 2015's Galaxy S6 line is the first time the company has announced and released two sibling models simultaneously. Make no mistake, though: the hardware differences between the two handsets are mostly skin-deep.

Where the S6 has straight sides, the S6 Edge tapers on its right and left sides, where the curved portion of the screens arc to meet the back. Though it feels slimmer, the Edge is a hair thicker in its fattest part, but also a tad lighter. The power button and nano-SIM card slot also move up top on this variant.

Weight (ounces) 4.9 4.6
Weight (grams) 138 132

The Edge also has a slightly higher capacity battery, presumably to work with night mode on the Edge display: 2,600mAh on the Edge versus 2,550mAh for the standard S6. The Edge gives us an average of 13.5 hours of battery run time in our looping-video tests, an hour over the S6's 12.4-hour average. Keep in mind that these tests don't take into account real-world longevity, especially if you're constantly using the Edge screen features, like night mode.

While both the S6 and S6 Edge are available in gold, black and white, Samsung throws in some color to each lineup. The Edge's portfolio gets jewel-toned emerald green, while the S6 springs for topaz blue.

Besides the unique screen and the few subtle distinctions listed above, the S6 Edge is otherwise identical to the standard S6. That includes the same 1440p ultra-HD screen, 16-megapixel camera and Exynos octa-core processor.

See my in-depth Galaxy S6 review for more details on how that translates into performance and everyday usage, and rest assured that the Edge delivers the same experience. (Except for the screen features and design flair -- which are, in fact, pretty cool.)

Design: Two curves really are better than none

Rounded glass on the left and right sides of the 5.1-inch metal-wrought Galaxy S6 Edge give this phone its name. The curved portions of screen meet the phone's back to form symmetrical ridges on either side and a kind of flattened bubble effect on the glass itself.

This actually works out better than it sounds. Its unique shape pops, giving it plenty of in-hand appeal. The phone feels aggressively slim, yet balanced, and the sharper sides provide a surprisingly solid grip.

While I had no problem fumbling the device, all that slim glass gives it a much more petite and delicate look and feel than a lot of other phones. You may feel more comfortable protecting all that investment in a case. Unfortunately, there aren't a ton of options at the time of this writing (but I'm getting in a gaggle of cases to find my favorite, and will update y'all soon.)

Compared with the S6's familiar rectangular shape, the S6 Edge is palpably modern and chic. If you're wondering, the Note Edge felt the same way despite its asymmetry, though I like the way this Edge looks even more.
