Stephen Hall, writing for 9to5Google on the results of a bend test conducted by SquareTrade:
The iPhone 6 Plus bends under about 110 pounds of pressure, and
reached “catastrophic failure” at 179 pounds. The Galaxy S6 edge
reached its bending point at the same amount of pressure as
Apple’s phone, but didn’t fare nearly as well overall. The S6
screen cracked at this same bending point pressure, and saw its
complete destruction at a lesser 149 pounds.
