Personally, 5 of the 6 phones I've used in the last 14 years were still in great condition after the ~2 year contract period that I used them for (plus the one I'm currently using, but I don't get credit for that yet as it's only 4 months old). The one exception got dropped on a bus, and still works fine, but has a cracked but still functional screen.
I think most people are more like me, but there are indeed a non-negligible segment of the population like you (and my sister) who just destroy their phones. Based on everything I've seen, it's definitely more of a you thing than a modern phone thing.
To be honest, subjected to a "mildly aggressive & negligent" usage pattern, like mine, even an iphone will barely last more than 3 years and it will be in "far from good" condition after 1 year of usage!
Modern smartphones are simply not built to last unless you take exceptional good care of them. Or maybe it's just that me and the people I know tend to be "exceedingly violent" with our smartphones, dunno...
