The comment complains about the device itself, and not any specific components of it.

I didn't complain about anything. I'm using an iPhone from 2018, but I have to charge it every day. Would be nice to not charge it at all from the time I buy it (like a nuclear power source)
Your comment made it sound like you were unhappy with the longevity of the device itself.
