Hearing someone drops their phone on average 50 times more often than i do i find wild. Good points in the other comments though as I have never used cases on phones before so i'm likely subconsciously more careful with them. Also typically in slim fit jeans pockets which are nearly impossible to accidentally drop out of.
Once I was getting off my jeans to do the Royal Squat and they decided to barf my phone. It fell like from 30 cm high, hit the ground exactly on the corner. Screen cracked edge to edge.
