Had my last smartphone, Honor 20, for 6 years, it didn't get any safety updates for the last 3.. Bought a refurbished iPhone 2 years ago, I will either use that until the safety updates stop or until I ragequit myself out of the modern society. Whichever happens sooner, following the ID laws and all.

But my main phone is a dumb Nokia I found from the trash. I don't see it breaking and they do sell aftermarket batteries still, so no issues. Can call mom and so on.
