The next time I need to protect a block of wood, I'll come back and check out this article.
I recently dropped a Nexus 5 in a "bump" case from waist height. There was no scuffing, no scratching, no obvious damage. However, half my screen was blank, and the touch screen did not work correctly.
Honestly, smart phones are much too fragile, but tests like this one really don't help.
How about running a drop test on every phone you test? Waist height and ear height would answer most of our questions. And then, rate any phone that doesn't survive as "unacceptable". When looking at cases, why not look at their warranty. If they don't put phone replacement into their warranty, rate the case "unacceptable" - I mean, if they won't stand behind the one reason for having a case, why should we buy that case?
