I bought a new phone every year, until i bought the Oneplus 5, in 2017. Until then, every new Phone had a "wow"-effect, big differeces in speed, camera, ...
Right around that time, phones have gotten so good, that i stopped buying new ones, there is no need anymore. You buy a new phone and the camera is 5% better, you wont see that. I now buy new, when the Phone doesnt get Updates. Currently on Fairphone 4, running Lineage OS. Next Phone will probably be a Fairphone again.
