You mean updates that intentionally slow your device so that you will want to buy the new model?
I wouldn’t expect a device that’s likely being drained and recharged daily to retain full capacity after two years. To suggest that shows a lack of understanding in the basic physics of a battery.
No company, Samsung, Google, etc. will “recall” your phone for normal wear and tear items like a battery. If that’s what you’re expecting, you’re going to be very disappointed.
The issue is not that battery degrades, it is that their phones could not handle it and shut off when charge still remained. 2 years is a very little time. None of the devices with batteries I had exhibited that behavior. And I have devices that are over 5 years old in regular use.
It’s not faulty devices, and a quick google search will show you that cell phone batteries have a lifespan of 2-3 years in average.

It's true that overtime iOS has become way more bloated, but they have released major updates which actually sped up older devices because they were focused on bug fixes and improvements, rather than something that's flashy and looks good in a commercial.
Is it a useful tactic to sell more phones? Absolutely. It also means that iOS completely destroys Android's statistics on % of users who run the latest version of their OS.
