We've Reached Peak Smartphone (washingtonpost.com)
You don't really need a new smartphone. From a column on the Washington Post (may be paywalled): Sure, some of them squeeze more screen into a smaller form. The cameras keep getting better, if you look very close. And you had to live under a rock to miss the hoopla for Apple's 10th-anniversary iPhone X or the Samsung Galaxy S8. Many in the smartphone business were sure this latest crop would bring a "super cycle" of upgrades. But here's the reality: More and more of Americans have decided we don't need to upgrade every year. Or every other year. We're no longer locked into two-year contracts and phones are way sturdier than they used to be. And the new stuff just isn't that tantalizing even to me, a professional gadget guy. Holding onto our phones is better for our budgets, not to mention the environment. This just means we -- and phone makers -- need to start thinking of them more like cars. We may have reached peak smartphone. Global shipments slipped 0.1 percent in 2017 -- the first ever decline, according to research firm IDC. In the United States, smartphone shipments grew just 1.6 percent, the smallest increase ever. Back in 2015, Americans replaced their phones after 23.6 months, on average, according to research firm Kantar Worldpanel. By the end of 2017, we were holding onto them for 25.3 months.
I believe the term that you need is "market saturation" of "good enough goods". The new devices promise more CPU and GPU power, but most people including me do not tap that power. It also does not help that recent OS versions have changed graphics, and people do not want to learn old things anew.
I still find it disturbing up to this day that every phones older than a few years old gets out of support for security updates. Too many Android devices with old unpatched firmware in the wild. Iphone? 4 and a half years later and no more updates from Apple. The hardware might be robust, but manifacturers donâ(TM)t give a shit about keeping security & os updates indefinitely. Thatâ(TM)s a major problem. Thoughts?
The planned obsolescence via expensive, non-user replaceable batteries isn't working like it used to. It's time for phone makers to come up with a more expensive part to wear out, one which can't so easily be manufactured by third parties. How about they start designing the screens to get dimmer over the life of the phone, so that by the third year they're completely dark? That should do the trick to get the upgrades rolling again.
