The damage done to a phone (or anything) on impact is going to be due to the power profile of the impact and, basically, power=energy/time. A soft case is going to increase the amount of time in this equation, hence lowering the power profile of the impact. There is other physics at play here, but that is the main issue with any concussive impact. So, take it from someone with a physics degree, tend towards a soft case unless you have irrefutable proof that a hard case will provide more protection.Yes this,
Another physics problem though is landing on a narrow point where the total force is expressed onto a very small inflexible surface area.
The ideal case would have an outer 'armor' of a hard material to spread out the force, probably also a stiff closing cover over the fragile and nonflexible glass, to protect against a point impact event spreading the force onto adjf873_n-s's described soft inner armor to extend the ∆v over time reducing the peak Gs experienced.
I have an Otter brand hard/soft case like this for my Nokia N900 and a Trident brand hard/soft case for my Asus/Google Nexus-7 2013 which have served me well over the years with damage only occurring to the tablet when out of the armor The N900 is so small there was never an event where the fall had enough mechanical advantage to damage the uncased metal bezel screen or slider rails. All of my N900s died from either PCB flex de-balling the modem IC or USB port breaking solder points form the PCB(new lead free solder and weak solder pad only anchored microUSB design) never impact, maybe one or two from static discharge into the USB.
