Good to know it's Bentley.
Here's the thing about percentage markup vs. gross dollars (or pounds). Sure, Apple has cultivated a premium product image and premium pricing, and manages to garner an unusually high gross profit margin as a result. If you look at Bentley, you'll actually find something similar - Bentley's gross profit margin is likely to be significantly higher than the mass-market automotive marques, as they do sell far fewer units.
What really matters, though, is that if Bentley clears $20,000 (10%) on the sale of a $200,000 car (and the dealership clears something comparable), that $20,000 can cover a lot of sins and customer creature-comforts, at a fairly small percentage of the overall sum. Bentley's costs for replacing a failed fuel pump aren't going to be all that different than Ford's or Toyota's; a veritable drop in the tank compared to the overall profit. However, repair costs for Apple don't leave nearly that much breathing space.
Even if Apple clears $300 on the sale of an iPhone (which it doesn't, as gross profit margin is not the same as net profit, and list price is not the same as the price they get from phone carriers and third-party dealers), $300 doesn't cover nearly as much. A whole-unit replacement of an iPhone Xs may cost Apple $300. The cheapest possible repair for Apple (battery replacement) costs them more than the $29 they're currently charging (the deficit is written off as a public relations expense, no doubt). If you factor just the labor involved in handling that battery repair (let's say a 20-minute phone call to AppleCare, another 15 minutes at the Apple Store for diagnostics and intake, 20-30 minutes of repair bench time, and 10-15 minutes at time of product pickup) - we're already well over an hour for labor, without spending a penny on parts or the overhead costs of maintaining a repair shop.
While Apple's products are considered luxury goods, they still don't match the conventional economic model for luxury goods (grossly smaller unit sales than the mass-market brands, compensated for by grossly higher net dollars per unit). They're really mass-market sheep in luxury wolf's clothing. Apple is still dependent on selling large quantities in order to make ends meet - it's just that they can sell smaller large quantities than the competition and still make a generous profit. Call them pseudo-luxury goods if you will. This is not Rolex or Patek Phillipe vs. Swatch ($2,000-$10,000 watches vs. $250 watches - a 10:1 or higher price ratio).
Sure, if you buy one of those jewel-encrusted iPhones from the companies that produce them, you should expect service befitting those Tiffany/Cartier prices. But $1,000 is not a Bentley, Patek Phillipe, or Cartier price tag. well, you can spend $1,000 at Tiffany - their web site even has an Under $250 category. The question is, just how much "luxury" service should someone aiming to spend $95 on two decks of Tiffany playing cards expect (unless they're buying thousands of them for corporate gift-giving)? If you want to be seated in a private sales room with a flute of champagne while goods are brought to you for inspection, you have to be spending a whole lot more than $95 or even $1,000.
