Adressons d'embl\u00e9e l'\u00e9l\u00e9phant dans la pi\u00e8ce : \u00e9videmment, le Galaxy S8 est plus puissant. Beaucoup plus puissant \u00e0 dire vrai, puisqu'il profite du nouvel Exynos 8895 grav\u00e9 en 10nm<\/a>. Ne vous fiez pas \u00e0 son simple nom, qui fait “+5” face au S7 : cette gravure lui permet d'atteindre de meilleures performances, tout autant que de favoriser l'autonomie s'il en a besoin.<\/p>\n

En dehors de cela, il faut avouer que peu de choses changent. Nous n'aborderons pas, par exemple , les diff\u00e9rences en photographie puisque les deux appareils disposent du m\u00eame capteur dorsal de 12 m\u00e9gapixels. A l'avant, le capteur 8 m\u00e9gapixels \u00e0 autofocus risque d'\u00eatre une belle am\u00e9lioration toutefois.<\/p>\n

Evidemment, l'\u00e9cran du Galaxy S8 et son design sont des atouts<\/h2>\n

Finalement, le principal changement que l'on notera entre les deux t\u00e9l\u00e9phones est bien s\u00fbr l'arriv\u00e9e du design borderless qui lui permet d'avoir un grand \u00e9cran de 5.8 pouces WQHD+<\/a> sans trop enfler en taille. Celui-ci est en ratio 18.5:9\u00e8me, le rendant beaucoup plus allong\u00e9 que son fr\u00e8re.<\/p>\n

Il gagne toutefois le HDR, lui permettant des contrastes plus profonds et des couleurs tr\u00e8s vives. L\u00e0-dessus, on ne peut nier une r\u00e9elle am\u00e9lioration des performances. Mais \u00e0 quel co\u00fbt ?<\/p>\n

Car malgr\u00e9 cet \u00e9cran plus grand et plus d\u00e9pensier en \u00e9nergie, la batterie des deux appareils reste la m\u00eame \u00e0 3000 mAh. De m\u00eame, celui-ci force le repositionnement du scanner d'empreinte au dos de l'appareil, jug\u00e9 malhabile selon les premi\u00e8res prises en main du Galaxy S8<\/a>.<\/p>\n
