I used to have the 2 year trade cycle for my phones. It's way too expensive for that now, Apple or android. The battery life on my iPhone 12 is losing some steam now, but I've already decided that when the time comes, I'll just replace the battery. Theoretically, I could get rid of my personal phone and just use my work phone for everything, but I'd rather have my two phones then be tied to my work phone for everything.
