With a quad-HD+ 2660 x 1440 resolution that looks super-sharp That may be, but their battery life indications are based on it running at the default 1080p not 1440, so that they can fudge the battery life stats to make it look similar to the S7 when it’s not ( the S7 battery numbers were based on it running its full 1440p resolution because the ability to change resolutions only came with Nougat, so they are not comparing like with like) .
