5 Make the Device Cheaper (Obviously)
The simplest thing that Apple could do to alleviate slumping iPhone X sales is this: just make the device cheaper. The iPhone X’s higher cost may be justified in some respects (OLED isn’t cheap), but there’s no doubt that it puts the device out of reach for a wide range of customers.
Even for buyers who can afford the device, its features might not justify the extra cost over perfectly capable devices like the iPhone 8 or 8 Plus. Of course, the problem with this is that Apple wants the iPhone X’s price tag to reflect its premium tier position. For Apple to still hammer down on that strategy, it might also have to drop the prices for lower-tier devices (like iPhone 8).
