3 Water Resistance
Since their debut, iPhones have not been friends of liquid. It was only Apple’s iPhone 7 and 7 Plus lineup — which launched in 2016 — that actually introduced some measure of protection against the elements, with IP67 dust- and water-resistance.
But Sony’s Xperia series have long been marketed as “dust and water proof” devices. And basically all of Samsung’s flagship devices have had some measure of IP-rated protection since the Galaxy S5 handset was first released in 2014. On this matter, Apple lagged behind quite a bit.
