According to Apple,iPhoneThe XS and XS Max feature the most durable glass in the smartphone and are IP68 rated. IP68 waterproof means that it can be used for 2 minutes under water for about 30 minutes.
In the SquareTrade test, the iPhone XS and XS Max did not have any problems in the liquid, but they broke in the drop test. As with the iPhone XS and XS Max, large areas of fragmentation can occur when dropped from a height of 6 feet onto a hard floor.
In the 60-second roll test, the iPhone XS and XS Max also showed cracking of the glass. In the bend test, when the iPhone XS received about 250 pounds of power, the screen shattered. The new iPhone damage scores given by SquareTrade are iPhone XS 86 points and iPhoneXS Max 70 points. The higher the score, the easier it is to break.
Overall, the iPhone XS and XS Max are more durable than last year's iPhone X, but you still need to be aware that if you fall, it is easy to break.
