When you drop it with a case it doesn’t matter. I think you unconsciously become a little more careless when using a case because you know your phone has a 99% survival rate when dropped whereas if you drop your naked phone on a hard floor or pavement, the minimum expectation is that you will end up with minor cosmetic dinks and scratches in addition to a fairly large chance of cracked glass on the back or front. Not worth the hassle in my opinion to get it repaired just because it “feels better” to hold.I actually dropped my 13 Pro more with a case on than I ever did in the 8 months it was naked.
It was far gripper naked than my wisteria leather
It is also not environmentally friendly to constantly get your phone repaired or replaced just because you have a cosmetic preference insofar that you like the look and feel of a naked phone.
