Can you give me an example of an AMD Laptop with 15-20 hours of battery life on Linux?

  I'm here for the same answer. I would buy one NOW.

  Yeah. I’ve got a 6800HS Ryzen Notebook with a 70Wh battery and I get like 8 hours out of it.

  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.

  (Only) On HN, I find this odd. I'll openly admit this is unreasonable for the "average consumer." So I'd never think to suggest mucking about with their systems. However, for tech-literate folk, if you really need extreme battery life, limit short/long TDP max values. If you are willing to use a noticeably slower machine because you value battery life, then instruct your machine to behave accordingly. It takes seconds and is way easier than writing any program. Zen 3+ cores are still quite fast with a 10/15 watt long/short power limit. On the Intel side, CPUs can further be instructed to disable all but 1 P-Core. Modern processors are pretty dynamic. I'm not pretending this will get you to arm levels of idle power draw, but things aren't an order of magnitude off, either. As a bonus, when you are plugged in, you get way more power on tap compared to any snapdragon.

  Lenovo T14 gives me about 12h. However that's with the much faster CPU.
