SquareTrade computes its score by looking at things like water resistance, the front and back panels, the grip of the device, the edge, construction and materials, and more. It also tests devices for the dangers lurking around with every day use. The Samsung Galaxy S5 scored high in the dunk and drop test.
The Breakability Score ranges from 1-10 with a higher score meaning that a phone is more likely to break in an accident. Scores of other high profile devices include the HTC One (M8), which scored a 6.5 due to problems with the dunk test and slide test. That is much higher than the 4.5 received by the first HTC One. The Apple iPhone 5s tallied a 5.5. The LG Nexus 5 failed the dunk and drop test, giving it a 7.
