A case is intended to do one of two things. The cases I get - like the Cruzerlite - are not meant to protect against any meaningful drop. They keep you from scratching your phone and that's all. The other cases - and I'm looking at most of the rest, including Otterbox - are mostly designed to LOOK like they could protect your phone, not actually protect it from any hard knocks. A case has to do at least one of two things - spread the impact out over time and/or spread it out over the surface of the device. Preferably both. The phone WILL experience the deceleration that goes with a drop impact - it has to - but if the energy taken up is spread out it's less likely to damage the phone. But a case that can do these things is necessarily going to be bulky - not a good selling point.
Cars deal with this sort of thing with crumple zones - areas that slow the impact down and spread the energy dump out over time. But hard cases - in particular those slim, form fitting hard cases - seem more likely to just provide a handy container for the pieces and shards. I know - there are lots of stories about how "My case protected my phone from a 5 foot drop!" But there are just as many stories of "I dropped my uncased phone from 5 feet and not a scratch!" or "I dropped my phone in brand X supercase and it shattered into hundreds of shards of broken glass!" I wonder if ANY case maker uses actual design tools like FEA simulators and then perform controlled drop tests, or do they just hire a graphic design major and let it go at that?
And yes - this post IS intended to get people thinking, and will possibly annoy some who swear by their cases. But are you sure what you bought is going to do what you want? Or does it just look it it ought to?
