My old x270 got that kind of battery life, on Linux, and that was 4-5 years ago. Granted, it was an Intel i5 and not AMD, but AMD had a negligible presence on the laptop CPU market at the time.
Every laptop I've run with Linux in the last 6 years just works out of the box with pretty much everything working: Lenovo, HP, Acer, Dell. I don't know if it's a distro thing or if I'm just lucky or what, but I never really need to do much special.
