And I’m sure you don’t know “anyone that still watches TV” like the old Slashdot meme.

It’s really not that hard to find statistics. It’s 2.5 - 3 years

You said "I'd guess 99% of the population makes a phone last 2-4 years." Which is obviously false if the average is 3 years. An interesting data point neither of these articles have is the standard deviation. One of the articles says 8% of people wait more than 5 years.

I never said any such thing about “99%”

Ah sorry, I replied to the wrong comment.
