Doesn't matter unit or revenue, there is no way it is down to 20% within "one year". And this is specific to Modem, not patents.
You are presuming that Apple doesn't "backport" their modem to a subset of the current products. It won't be that hard. The iPhone 13 for instance. ( iPhone 13 Pro teardown pics below step 8 ).
The iPhone 13 might look like an incremental update from the outside, but we’ve got a feeling there’s more lurking beneath the surface. We took a...

There is a 'sandwich' of two boards there. One is the radio stuff and the other is the "computer" (SoC , storage ) parts. The 'tops' of the two boards decoupled.
The Orange and yellow outlined chips are the Qualcomm ones. If Apple simply makes another board with a Apple modem and RF module that use the same (or less) power, dimensions, and the same SoC to Modem interface standards, then they could make a Qualcomm-less version of that daugtherboard. Couple that to the other board and ta-da .... lower Qualcomm sales. This isn't some giant moon-landing complexity project. Especially, if they give themselves a couple of years to do it.
The logic board assembly in the current ( designed in the last year or so
after Apple bought the modem division ) have modular "radio" daughterboards. Modular means replaceable.
Apple could straightforwardly have an Apple modem chipset in hundreds/thousands of iPhone 13's in Early 22 as a test mule harness to validate the chip in the field. ( doesn't necessarily need to wait for 2022 or 2023 designs to finish before starting. )
' Back of the envelope numbers' just to put it into a more grounded context. If Qualcomm is charging $130 for their two chips and Apple can make their "clone replacements" at $100 that is a net saving of $30. Say legacy phone make the switch for sells 4M. So that is $120M. Even if the R&D for the board and recertification cost Apple $25M (which likely no where near) that would mean Apple would net $95M with the switch. Your hypothesis is that Apple would pass up double digit millions in net revenue to give Qualcomm more money. I wouldn't be on that. Neither is Qualcomm.
Even if the gap between the two is only $8 , that is still $16M which is likely close enough to breakeven.
This primary issue is that if Apple plans ahead to replace Qualcomm, then it won't be that hard. If planning ahead it also wouldn't be hard to design an Apple modem that can be 'dialed back' to 2021 feature set even if trying to do something that will compete fully with Qualcomm's solutions in 2023. They could make a 'mode' that matches the iPhone 13 so there is no significant specificaiton change. Just another SKU. ( which if they are at a transition to a "gets cheaper because another year older" phase change ... not that hard to introduce a new SKU).
Apple will pay Qualcomm Patents regardless of using their modem or not. So changing modem doesn't impact their patent license agreement. But yes they are simply downplaying the effect of a no apple as customer future.
the patents don't come with the "% of device" costs. Qualcomm's margins are the bigger issue.
Apple doesn't really doesn't much care about the Qualcomm patent revenue payments they'll still have to make , Apple will just make the end customers pay. Slapping a 20+% markup on on higher BOM costs just makes them more money anyway.
Except that is not how it works. That is not how Just in time works, nor how up to or guarantees works. The flexility of cohttps://9to5mac.com/2020/07/13/apple-samsung-oled-payment/ntract only works when you have a basket of choice in supplier, like DRAM or NAND. Not to chips with single vendor, and especially for leading edge node fab capacity.
No. Just in time has a major component in inventory control. That is a different dimension that trying to pit multiple suppliers against each other. For example.
"... Samsung is the sole supplier of the 5.4-inch panel used in the iPhone 12 mini, the smallest model of Apple's 5G-supporting iPhone 12 series. ... "
Apple is likely to reimburse Samsung Display over a shortfall in OLED panel orders owing to lower-than-expected demand for iPhone 12 mini models,...

"... Apple has agreements with many of its suppliers to make a minimum purchase, likely to achieve lower prices per unit. If Apple fails to hit that minimum purchase, contracts usually stipulate that a penalty will apply. This year, Apple’s supply chain and demand were both affected by COVID-19, which could explain what led the company to order fewer OLED panels than initially expected. ... "
Apple has reportedly made another payment to Samsung for selling too few iPhones. According to a new report from Display...

Companies that do not have Apple's "800 lbs gorilla" status may also use just-in-time to play off competiting suppliers against each other. Apple is just far more direct in doing risk shifting. Pointing that the opportunity to make lots of money if the volume is high ( " we're Apple , hordes of fanboys stand in the rain for our products... we will sell alot" ) , but deeply Scrooge McDuck at the same time. Discounts and more than willing to stick the supplier with hefty problems if things go wrong.
Apple withheld payments and sued Qualcomm. Pretty doubtful they are out to end the supplier relationship without a departing "FU" on their way out the door. Apple will likely pull out the full "800 lbs Gorilla" when doing to the "ending" contract terms.
Every Monday morning Apple looks at sales of all the products. If there is an identifiable trend of substantive mismatch between what they have ordered and what they are selling.... Apple bumps the brakes on buying. That is how their contracts are set up. Apple spends tons of daily/weekly effort to keep from buying "too much". The whole infrastructure, including their supplier contracts, is set up that way.
