Design: bigger screens but heavier smartphones

The first time you see the S8, you notice a big difference between its screen and that of theS7. Both versions of the S8 have a left and right curved screen, whereas previously only the S7 Edge offered this format.

Really?

The S8 also uses a single glass panel, eliminating the physical docking button found on the S7 and previous Galaxy smartphones. Instead, the S8 and S8+ integrate a virtual button in the same place. It also works with haptic feedback, in the same way as iPhone 7.

The S8 and S8+ have larger screens than the S7 and S7 Edge, with a display of 5.8 inches for the S8 and 6.2 inches for the S8+. The S7 (5.1-inch) and S7 Edge (5.5-inch) look like dwarves. However, this is due to the extremely thin rims, which make it very easy to handle the smartphone with just one hand, especially the classic S8.

The weight of 155 grams of S8 is close to that of S7 (152 grams). The difference between the 173 grams of the S8+ and the 157 grams of the S7 Edge is more noticeable. In addition, the Galaxy S8 and S8+ are 1.5 mm thicker than the two versions of the S7. However, this development should not be felt with use.

The Galaxy S8 doesn’t give up buttons altogether, as Samsung’s new PDA, Bixby, has its own button on the right side of the smartphone. In addition, with the S8, Samsung has finally switched from micro-USB to USB Type-C charging. While this improvement is more than welcome, we would have liked the manufacturer to adopt the standard as early as last year.

Features: Lots of gadgets!

While Samsung has made some design changes to its Galaxy S range, the main changes are in the special features offered with the smartphone. Bixby is a virtual assistant that simply allows you to use your voice when it makes more sense than typing on the screen. For example to ask “send this picture to my mother” or “turn on the light at 25 percent”.

Really?

The Samsung Connect application allows you to control different connected devices from a single interface. Finally, the additional DeX dock turns the Galaxy S8 into a minicomputer, to launch Android applications on a real monitor with a keyboard and mouse interface.

Audiophiles looking for new earphones will be happy to know that the Galaxy S8 comes with a pair of wired earphones designed by AKG, a rather high-end brand. It should also be noted that these headphones will also be commercially available at a cost of $99.

Display: always wider, always bigger, always better defined!

Next to the Galaxy S8 (5.8-inch) and S8+ (6.2-inch), the screens of the S7 (5.1-inch) and S7 Edge (5.5-inch) really look like dwarves.

Really?

The S8’s screen offers a resolution of 2960 pixels by 1440, with a ratio of 18.5:9, compared to 2560 pixels by 1440 and a classic 16:9 ratio for the Galaxy S7. In addition, the S8 and S8+ are compatible with HDR content. In concrete terms, compatible films and series will be displayed with more colour and contrast than with a conventional display.

Photos: some improvements

The Galaxy S8 offers the same 12-megapixel dual-pixel photo sensor as the Galaxy S7, but Samsung has promised software improvements over last year’s model. Thus, for example, the clichés should be less blurred.

Really?

On the front, the 8-megapixel photo sensor on the S8 and S8+ offers an improvement over the 5-megapixel selfies sensor on last year’s models. These cameras now also feature autofocus and face recognition, which is handy for group selfies. 

Biometrics: say “cheese”!

On the Galaxy S8, it is possible to unlock the smartphone using facial recognition or the iris scanner, two options not offered by the S7. Samsung’s new smartphones also include a fingerprint reader located on the back of the device next to the photo sensor. It’s best to learn to recognize the reader by touch to avoid dirtying the smartphone’s photo lens. Last year, the Galaxy S7 offered a welcome button, which also served as a fingerprint sensor, located at the bottom of the screen.

Specifications: more power

In France, the S8 is equipped with a 64-bit eight-core processor, Samsung’s Exynos 8895 (in the United States, this is Qualcomm’s Snapdragon 835). According to Samsung, this is the first processor with a 10 nanometer engraving, making it both more powerful and more energy efficient.

Compared to the Galaxy S7, there should be an improvement in performance, especially in games. At the time, Samsung’s smartphone was carrying the Exynos 8890, one of last year’s top processors. Since then, however, several devices have surpassed the power of the S7, such as the iPhone 7 or the Huawei Mate 9.

Samsung has doubled the storage capacity for its Galaxy S8 and S8+ compared to last year’s models, from 32GB to 64GB of storage. Note, however, that smartphones can still accommodate microSD cards. Finally, the RAM remains the same, with 4 GB of RAM on the counter.

Autonomy: please see

The S8 and S8+ batteries are similar in size to their predecessors. Which leaves us wondering about the autonomy of the new smartphones. The S7, like the S8, has a 3000 mAh battery, while the S8+ has a 3500 mAh battery, slightly less than the 3600 mAh battery of the S7 Edge.

>>> Smartphones: what are the best models in autonomy?

How will these batteries be able to power larger screens? We ask to see. It is possible that the improvements promised by the Exynos 8890 or the Snapdragon 835 will succeed in cancelling this a priori necessary power.

Rate: not for all awards

In France, the Galaxy S8 is available for pre-order at 809 euros, while the S8+ is available for 909 euros on Amazon. Much higher rates than the Galaxy S7 and S7 Edge today. On Amazon, the Samsung Galaxy S7 can indeed be purchased for around 480 euros, 530 for the Edge version.

Balance sheet

For those who are dying to have a smartphone straight out of a sci-fi movie, the S8 is an excellent evolution of the S7. Whether it’s the on-board display, PDA or home automation control, the S8 and S8+ look like they’re worth the detour.

Really?

On the other hand, it will be necessary to be able to test the smartphone further to see if the new Galaxy S8 processor is powerful enough to make it one of the best smartphones on the market, especially in terms of battery life. In the meantime, the Galaxy S7 remains an excellent alternative, especially for tighter budgets.
