Galaxy S8 and S8+ specs review: to infinity and back

Here it is, April the giraffe's baby #TheNextGalaxy, and it is every bit as impressive as the leaked renders and the rumor mill suggested. How about the best record screen-to-body ratio in its flagship class? Check. The fastest, most frugal chipsets available? Check. Futureproof display aspect? Check. 64 GB of base storage? Check. Autofocus selfie snapper? Yep. And on and on.

Samsung has outdone itself with the Galaxy S8 and S8+, and has even bumped the launch price a bit, that's how confident it seems in its new phones, given the eventual brand damage from the Note 7 recall. The company had a chance to redeem itself, and the Galaxy S8 is poised to be its knight in a white shining armor - or, Coral Blue one, if you prefer. There is more to the S8 and S8+ that meets the eye, so let's dive into the nitty-gritty aspects of the two flagships that Samsung announced.

Design

Record screen-to-body ratio among flagships, Gorilla Glass 5 protection - welcome design twists

No matter how you slice it, and ceteris paribus (Google it), we want the largest possible screen in our phones to browse or enjoy media, at the lowest possible footprint in our palms and pockets.

Boy, does the S8 deliver on that front. Samsung stuffed no less than six elements in the top bezel, including a face recognizer set, ditched the home key, moved the scanner on the back, and slimmed the bottom bezel in a never-before-seen manner.

All of those resulted in a phone with 83% screen-to-body ratio. To wit, this is close to the 84% of the current record holder - the Mi Mix - and more than Sharp's infamous EDGEST display designs. Granted, this number is helped by the curved display sides, too, but the slope here is very minimal, and mostly for aesthetic, rather than any functional purposes. Samsung calls this technology Infinity Display, and intends to employ it in future flagship devices, too.

Thermoforming, nanocoating - that's how Samsung calls the processes it employs to reach the glass sandwich designs of its phones. The Galaxy S8 back, and its curved flexible display with plastic substrate, are covered with a "3D Thermoforming" tech, which places the protective glass between two molds, heats it to 800 degrees Celsius, and then the cover glass gets pressed into the perfect symmetrical shape we see sloping towards the sides of the S8 and S8+.

The shiny colors of the phones are achieved by a nano-thin multi-coating process that resulted in a polished finish that looks patterned from up close. The tapered, symmetrical cover glass allowed for thinner metal frame and buttons, which is important, as now we have a brand new one on the left that launches the Bixby personal assistant.

All of these technologies return a brand new design for the Galaxy S-series, and the Galaxy S8/S8+ are also the smallest phones for their screen sizes as a result. Don't get us wrong, the S8+ is still one big mofo, but this time Samsung has put a 6.2" panel in a size that big-screen phone lovers are accustomed to anyway. They were just accustomed to having 5.5 or 5.7-inchers in this footprint.

Infinity Display

Samsung gives edge-to-edge new meaning with the "Infinity" Galaxy S8 display

The "Infinity Display" of the S8 and S8+ impresses not only with the sheer space occupancy at the front, but also with its higher, WQHD+ resolution of 2960x1440 pixels. Thus, the rumored 18.5:9 screen aspect ratio may turn out true in the end. This new standard, called Univisium, is similar to what LG did with the G6, and allows for taller, narrower devices. The default FHD+ screen setting of the S8 is actually 2220 x 1080, while the new HD+ is 1480 x 720 pixels. While apps, games and video that are done at 16:9 will be letterboxed in the beginning, the Univisium format is the future of movie and TV series capture, so the content should be adjusted soon after there is a critical mass of devices that can employ it fully.

Samsung has employed a pressure-sensitive bottom area on the Super AMOLED display for the first time, too. It serves a haptic home button purpose of sorts, so that you aren't completely longing for the clicky physical experience if you are coming from an older Galaxy.

Processing power and memory

The fastest, most frugal chipsets available are Galaxy S8 exclusive, and 64 GB is the basic storage - what's not to like

As is the case for almost every of Samsung’s flagships, each of this year’s Galaxy S8 variants will come in two separate versions – one for the US and China, running on Qualcomm’s Snapdragon 835, and one for the rest of the world, powered by Samsung’s own Exynos 8895. This comes as a result of Qualcomm’s firm grasp on CDMA-related patents, which all but guarantees their near-monopoly in the States, forcing companies like Samsung to release modified versions of their devices compatible with local bands.

It’s fair to say that the end user will probably never feel the difference, as both are now manufactured by Samsung with its class-leading 10nm technology, resulting in the most powerful yet most frugal chipsets currently available. Coupled with 4 GB of dual-channel DDR4 RAM, and 64 GB of UFS 2.1 storage, the S8 and S8+ can take on any task thrown at them in a breezy manner. Here are the specs and features of the two chipsets that power the Galaxy S8 and S8+.

Connectivity

In addition, the phones break a lot of important grounds when it comes to connectivity, and we aren't talking about the USB-C port, which is a first for the S-series. What we mean is that the phones are the first to land with LTE Cat. 16 and its theoretical 1Gbps download speeds. They will also be the first phones with the newest Bluetooth 5.0 standard you can get, for double the speed, and four times the range of the existing edition. Check out the video below, where T-Mobile demonstrates how the S8 can almost break the 1Gbps barrier on its LTE network.

Camera

Camera may sound all the same, which would be lame, but hold your horses

At first blush, the Galaxy S8 and S8+ still sport the same 12 MP camera with unique Dual Pixel autofocus system that their predecessor employed. Even if that were the case, it would still be an excellent shooter, as numerous camera comparisons of ours had already attested. Here, however, we have new tricks, new low-light algorithms, and a fresh 8 MP front cam with autofocus and the same wide f/1.7 aperture as the rear, promising Snapchat-worthy selfies (yep, there are a bunch of ear and sunglass stickers to try on, too). This leads us to the thought that there could be a brand new custom-made Sony or Samsung 12 MP sensors inside the S8 and S8+. Here are a few comparison shots between the S8 and other leading phones on the market we managed to take, for your viewing pleasure.

Battery life

Mixed bag when compared with the Galaxy S7 and S7 edge predecessors

The Galaxy S8 and S8+ exact battery capacities are now officially confirmed to be 3000 mAh for the smaller S8, and 3500 mAh for the S8+, which jibes with what we've heard before about the battery compartment of Samsung's fresh new flagships. The more frugal tech of the 2960 x 1440 pixels AMOLED display, and the new 10nm Exynos or Snapdragon chipsets have improved the official battery life numbers in comparison with the S7 and S7 edge, but only in certain categories like music playback. For video playback and Internet browsing, the numbers are pretty comparable, while the talk time endurance for the S8 and S8+ is slightly shorter than that of their predecessor.

	Samsung Galaxy S8	Samsung Galaxy S7	Samsung Galaxy S8+	Samsung Galaxy S7 edge
Battery capacity	3,000 mAh	3,000 mAh	3,500 mAh	3,600 mAh
Internet use 3G	11	11	13	12
Internet use LTE	12	13	15	15
Internet use Wi-Fi	14	15	15	16
Video	16	15	18	18
Audio	67	45	78	55
Talk time	20	22	24	27

Takeaway

$99 AKG ear buds and microUSB adaptor come standard in the S8 box

All in all, the Galaxy S8 and S8+ tick all the "best" boxes that a seasonal flagship could desire. They are the most compact for their screen sizes, and the fastest Android phones on the market. With the move to USB-C and the up-and-coming Univisium display aspect ratio, Samsung has managed to futureproof its 2017 flagships, in addition to waterproofing them. With the addition of a high-res autofocus snapper for selfies, the only ho-hum aspect in terms of upgrades remains the main camera, which, however, didn't need much in the way of upgrading anyway.

Thus, barring any subpar performances with call and image quality or battery life that might emerge, the Galaxy S8 and S8+ have seemingly achieved their goal to be the best phones money can buy in the Android universe, and Samsung seems so proud of its creations, that it has slapped a truly flagship price on them, so it all balances out in the end, doesn't it?

Heck, on paper these highly-anticipated April the giraffe babies fresh puppies could erase most of the brand damage that Samsung incurred during the Note 7 brouhaha, but we'll reserve our final verdict for the full review of the retail Galaxy S8 and S8+ that is soon to follow. What do you think?
