It's probably worth discussing the reasoning behind a statement like this. I don't pay attention to low-end Android phones - maybe they really do this to you. But it seems really unlikely.

Do you have examples?

I know many people complain about battery degradation. But really, these phones are using about the most advanced batteries that are available in the relevant price range. They are degrading because you are using the device a lot. You really are. Are there any credible claims that batteries are degrading faster than "normal" given usage patterns?

This is a common claim but I rarely see it supported. My iPhone 6S from 2015 is fully supported by iOS 15[1]. I know plenty of people whose cars had day 1 drawbacks in the on-board software which were never fixed (or required paid upgrades in the $500+ range) — and that includes things like “the entertainment system will crash every time you connect your phone because you have more than a small number of songs / contacts” — and most people I know who own cars upgrade them more frequently than every 6 years.

Your car still runs on gas and your phone still runs on electricity.

I think this statement is overly generous to car manufacturers, who rarely provide software updates. Is that not motivated by an analogous planned obsolescence?
