Those drop tests are made by amateur, i won't take them seriously....
to check the real effects, at IP-C (IPhone-Comparative) we consider in our thorough methodology:
- type of surfaces hit, hardest the surface, more dramatic the result.
- the angle the phone drops, because falling on the corner isn't the same as falling on the back or front.
- the height, higher it is more damaging it will be.
- the velocity it falls, faster the fall is definitely not good.
- the wind conditions , because it may influence the angle
- humidity, because glass is sand so liquid will have influence.
- luck factor, because if someone hexed you, it will probably break.
- the reflex of the owner, if he has good reflex, he can dramatically reduce the risk.
- the constructor honesty, because if the phone is secretly made of cheap components made by kids in some poor countries, no wonder...
- cataclysmic hazard, if you drop it while you were hit by a meteor, a train, lightning bolt or a tempest of grasshoppers, it has some effect too.
- godly influence, it is possible that greater beings may have influence on the test, several case shown that faith believers had less chances to break it than non-ones.
