I think it is linked to devices sold - and it is priced as percentage of the retail price. My understanding is that Apple do not agree with the price paid to Qualcomm being linked to the purchase price of the phone, which you can understand - why as a consumer should you pay more for the same IP if you want extra storage in your iPhone? I think this disagreement came around before Apple ramped up the prices with the X / XS / XS Max... We should have seen the canary in the coal mine :)
