That’s what I expect from a phone or laptop. I know car batteries are supposed to be more long lived, but I don’t know what makes one Li battery last longer than another. Many EV manufacturers haven’t been in the game long enough to prove it.
Short version; lithium cells operate on a sort of continuum between power density and peak discharge rate. Individual cells are usually built to drain only as fast as is needed to maximize how much total power they can hold.
The batteries for phones usually just have a single lithium cell, maybe up to three or four for some laptops, but the load of an electric car’s motors and electronics is spread among hundreds of cells. The relatively slow charge/discharge rate needed per cell makes for a slower rate of degredation overall compared to what you’re used to.

That’s very concisely and neatly explained, thank you.
