Also, iPhone 11 was $699, and now iPhone 12 is $799 or $829 if unlocked from Apple. $699 this year only gets you a "mini", but without the "SE" pricing.Apple‘s net margin is 21.4%. The manufacturing cost of the iPhone 12 is estimated to be about 21% more expensive than that of the iPhone 11. That means that not only did they not pocket the savings, they did not even cover their increased cost, so their net margin decreased.
When you say, Net Margin, instead of Gross Margin, you are saying money going to investors and stock holders only. That's after all the tax R&D, capx, insurance, benefits, and salary payments have been deducted.
No company should be making that much after all the deductions.
