Last week we asked you if you prefer the Samsung Galaxy S8 or the bigger Galaxy S8+ and the opinions seem very evenly split - the S8 won with 52% to 48%, a very narrow margin indeed. The primary difference between these two is the size (and, well, price). Sure, the plus model has a bigger battery, but that brings only a minor bump in endurance (our testing showed 84h for the S8 and 88h for the S8+). Normally, the smaller phone outsells the bigger one and we wondered if this will be even more true this year seeing how the Galaxy S8 already has a bigger screen than its predecessor...
