Like many others have said this is not true. I've had a nexus 4 (2012-2017) which I had to change due to battery starting to swell, also had a custom rom which might have helped. I upgraded to a Pixel2 in 2017 which I still have. I'm even considering replacing the battery instead of the whole phone since it's still doing just fine otherwise. I really don't need a better camera so why bother with a new phone that doesn't offer much more than what I already have. Both of those phone are/were caseless too, just be careful with your stuff and you'll do just fine for a couple of years. In my opinion people choose to change their phone more than they have to change their phone.
