SquareTrade, a company that offers insurance plans for smartphones in the US, recently conducted a test between Samsung Galaxy S6 Edge, HTC One M9 and Apple iPhone 6 Plus to see which smartphone is definitely more durable. So the final answer to Bend Gate.
Galaxy S6 Edge and iPhone 6 Plus bend when the pressure reaches about 50 kg (110 pound), with the difference that the screen of S6 Edge cracks being rounded (S6 probably react as iPhone Plus 6/6). For both, however there is a limit and S6 Edge is just under 68Kg, or 149 lbs, after which you will never go back, and the break is for sure, while iPhone 6 Plus is approximately 179 lbs
HTC One M9 is not missing but its different structure and placement of the center button in the middle of the body they see a threshold of 120 pounds, about 55 pounds, after which the phone will bend but not break even.
