This is the primary reason why I push the the non technically inclined (grandparents, older friends, etc) in my life to use iPhones. The latest Pixel I believe is now offering 6 years security patched (which makes it an Android leader), but 7+ years is already the standard on the cheapest iPhone option.

The argument of a $1000 Androd phone vs a $1500 iPhone falls over if you have to replace that Android phone 2 more times in the same period.
