How often do you buy a new phone?

How long do you keep your phone before buying a new one? It is based on this article that especially Apple fanboys, buy a new phone every year when the new one comes out.

I use a phone till it stops working. Usually get 3-4 years out of it. I usually will buy a refurbished “flagship” phone from the previous year or two. I like a big screen and lots of memory. I’m currently using a pixel 9pro xl. It’s fine. I like the idea of using graphene, but haven’t yet summoned the energy to do it.
