Much of the degradation comes from keeping the battery at full charge for long periods of time. Apple improves long-term battery life by lying about battery percentages and only charging once the battery gets below 90-95%. There's even a new option to only charge to 80%. I get the same behavior in Linux with TLP.[1] I run "tlp setcharge 75 80" and my battery only charges to 80% (and only starts charging if it goes below 75%). If I think I might need power for a longer time, I can run "tlp fullcharge" and wait for it to fully charge. TLP remembers these settings across reboots so I don't have to think about it. 1. https://linrunner.de/tlp/ https://linrunner.de/tlp/
