Getting excellent battery life on Linux nowadays should be as simple as installing the "tlp" (the laptop project) package. I can't compare to a Mac, but I use both Thinkpad and Latitude and on both get better battery life on Debian than colleagues on Windows 10 (also and related: much less fan noise...). Now he complains about battery life after one year. There is a Thinkpad feature that helps a lot: one can limit the charge level to a configurable value. And tlp does support this for Thinkpad. By just limiting the charge level to 90% for example, and making sure never to discharge the battery completely, one can greatly extend a laptop battery life. You can't use the range fully, but then the battery is much less stressed: Li-Ion batteries suffer at the extreme of the charge range. As the battery last enough for me (and charges quickly) I never found this range reduction to be a problem. And my 5 years TP battery is just fine. The Dell Latitude also supports this BTW, but it's in the BIOS and not integrated with tlp.
