Funnily enough I'm looking at getting a new phone because my pixel 6 battery no longer lasts 9am until 6pm without a mid-day charge -- I looked at the latest pixels (10) and they looked neat, but expensive; so took a look at the 9's, and saw they're basically exactly the same at 60% the price; then looked at the 8's and they're basically the same except 40% the price...

I expect the smartphone market to switch to a sales model where devices are somewhat more expensive, but more durable and to some extent more serviceable than in the past, so many will buy refurbished phones instead of new ones. I can see some similarities with the used car market, or hi-fi audio receivers, for example.
