On a scale of 1 to 100, where 100 is the poorest score a phone can get, the S9 racked up 71 points, the S9+ 76, while the S8 and S8+ tallied 76 and 77 respectively. The iPhone 8 survived SquareTrade’s grueling experiments better, scoring a 67 medium risk, whereas the iPhone X totaled a disappointing 90 points.
As for the gap between the Galaxy S9 and S9+, it appears the former can handle face down and side drops a little better, although the latter wasn’t as easily breakable in bend and tumble tests. The repairability of both swanky new phones is obviously not great, but for what it’s worth, the water test results are pretty impressive.
