And why not? iOS 12 made older iPhones run much better than they did on iOS 11, to the point where using a three-year-old iPhone 6S became totally viable, especially with a fresh new battery. And keeping an older phone is even more attractive for customers who were no longer making monthly payments for the device through the now-common installment plan. When faced with either buying a new iPhone — a minimum of $30 a month for two years — or upgrading iOS and spending $30 once on a battery replacement, it’s easy to see why many opted to keep their old phone around longer.

Every year when Engadget reviews a new iPhone, we note that Apple’s silicon offers far more power than most users need. The good news is that a few years later, those chips are still enough for most people. And given how the pace of other innovations in smartphone hardware have slowed over the past few years, there’s less reason than ever to upgrade every time a new iPhone arrives.

Also, for some users, buying an XS or XR isn’t so much an upgrade as it is a compromise. I’ve talked to plenty of people who just miss the home button — they don’t care about the bigger screen or supposed convenience of Face ID. They spent years getting used to the home button and find the change more an annoyance than an improvement. As with the headphone jack, it’s obvious that Apple will phase out the time-tested home button entirely, but people who prefer the old design are clearly not going to rush out and upgrade, particularly at the prices Apple is asking.

Despite the challenges Apple is facing, it would be irresponsible not to note that Apple has only said it isn’t making as much money as it expected to — that’s very different than Apple being “doomed.” Apple’s revised revenue projection for the quarter is now $84 billion. That’s about 8 percent less than originally forecasted, but it’s still the second-highest holiday quarter in the company’s history. The company also raised the average sale price of an iPhone from $606 to $724 over the last year, so customers clearly haven’t fully rejected more expensive devices.

Cook also says that non-iPhone revenue grew 19 percent — so despite the fact that basically all of Apple’s products cost a lot more than they used to, most segments are still growing. Wall Street investors may panic over an iPhone downturn (stocks are down about 8 percent today compared to yesterday, and they’ve been dropping steadily since peaking in October), but Apple is financially well-positioned for years to come.

It does raise the question about where future growth will come from, but Apple is still years away from needing to figure that out. (It also raises the question of if it’s even reasonable to expect a wildly successful company that’s been around for 40 years to grow year after year, but that’s apparently how Wall Street thinks.) In the meantime, investors will just have to get used to a world where iPhone buyers upgrade after two or three years instead of every fall.
