Apple did raise the price. The cheapest model was $699 last year. Now it’s $749
The display is the most expensive part of the iPhone. And the OLED is more expensive than the lcd.
The X was delayed due to supply last year. Or else it would have been released earlier.
The XR doesn’t have a supply issue. It’s cause they wanted people to buy the more expensive Xs/max.
So why doesn't Apple raise the price of XR to $799, $849, or even $899?
If the theory is the XR is underpriced and offers better value than Max, then Apple is clearly leaving money on the table. Apple wouldn't delay availability to fix a pricing issue. Apple would adjust the pricing on the XR.
The theory that Apple is deliberately delaying availability of the XR is bunk.
