On my Sony Xperia I can force battery limit to 90% or 80%, but on my parent's Pixel 5a only the automatic/adaptive option was available? This seems like one of those things that's easy to offer, but Google hides it to be more slick and apple-like, while Samsung and Sony add the control in for power users / "value-add".
(There are other trade-offs between Google and Samsung, of course.)
