So don’t buy one? You don’t need a new phone every 1-2y unless you’re a spectacularly well trained consumer.
I usually replace my phone every 3-4y when power efficiency and performance have significantly improved, or there’s a new radio standard that I need (5G, AX WiFi) or the camera makes me want an upgrade. If none of those things are true then use your phone until it dies 🤷♂️
