Sapphire vs Gorilla Glass- Bending and Impact


[vc_row][vc_column width=”1/1″][vc_video link=””][/vc_column][/vc_row][vc_row][vc_column width=”1/1″][vc_column_text]We scratch, bend, and break both Gorilla Glass, and sapphire side by side to see which is stronger, and which makes more sense on a smartphone.

The Math

We compare failure stress and strain for Gorilla glass and the Sapphire. We did this using a four point bend test and the calculations below. We also tested several dozen pieces.

    can we see pics of all the phones lying a flat surface out of the machine? and at what weight did you start to notice a deformation?

    The note 3 bends back into flat in the tests. Can you show after photos?

  • Tim

    The question is, can you bend it back?!

    The problem here is not flexibility, it’s resilience. iPhones aren’t resilient, they don’t go back to their original shape. Plastic, on the other hand, is inherently resilient.

    I’m sure this makes the dudes with bent phones feel MUCH better…

    I honestly am shocked.. no wait I’m not shocked over the iPhone bend controversy because i know how irresponsible people are. I mean seriously when we were kids we had fisher price stuff that was made tough for us because we were children who didn’t know responsibility yet but we are now adults with $700 phones that aren’t made to be sit on!! Do people need a company to just make tough ugly electronics that are nearly unbreakable because of the lack of being a responsible adult? If you are that bad then there is outterbox… i myself have not used a case on any of my phones since 2007 including all the iPhones. Never had a problem or drop and i am extremely happy with my iPhone 6 plus, best phone out there right now and all the professional reviews and tech sites are posting similar rave reviews as well

    Here is the point everyone, this only proves one thing, all phones will bend break etc. Even if we did the same test in the machine on the new Samsung coming out that is made with more metal as advertised then you are going to see the same or worse with the Samsung. The ones that get hurt the worst from all this Bendgate crap is the consumer reason is the companies instead of loosing money on returns because we as adults sit on our phone in our pocket the companies will stop making skinny phones and make them more thicker and stronger. This is all stupid dumb and retarded this even started, but now that it has started Samsung should get the same test done on their new released phones as well. Curious how they will turn out in the bend test??????

    one test is nice… but… that’s it… it just one test…. maybe the iPhone does slightly worse on this test…. but slightly better in another…
    overall… i tend to like the iPhones because of the operating system and the eco system…
    but… i buy the extra applecare cuz i know that over 2 years i don’t want to have to worry about dropping it or accidentally wearing the tightest jeans possible and doing calisthenics with the 6+ in the pocket…lol

    I would really like to see the same test done after the iPhone has been playing a Device intensive game while chargeing so it is nice and hot and then she how much pressure it can take as if you was playing in you phone on charge then put it in your back pocket and went in car would it be softer then when cold

    Thanks for share this. Now I know for sure what’s going on with the static using my Rode VideoMe Mic in the LG G3. The transceiver are very close to the microphone. Anyone know any other LG built with those transceivers far from the 3.5 jack?
