Linux seems equal in power management to Apple. On my ThinkPad X1 Carbon with the 57 W-h battery I get a good solid 8 hours of work and often the system consumes as little as 4W. My MacBook Pro with a 54.5 W-h battery runs for at most 4 hours. Now, it's true that I had to edit dozens of little configs to get the ThinkPad with Linux up to where a ThinkPad with Windows is right out of the box, such as enabling PCIe ASPM and making it still be enabled after resume from suspend, but to my knowledge there are not such power efficiency hacks available to the user on macOS, and it's bad by default.
- wwarner 8y agoThanks -- I'll have to put a bit more effort into this the next time I run a linux laptop.
- Sendotsh 8y agoDo you have a link to a good guide for setting up power stuff on the X1C? I've found a few but they conflict, so I'm keen to hear from someone who actually has it all working well.
- asark 8y agoThe biggest power efficiency hack for macOS is to avoid running JS anywhere other than in Safari, and there as little as possible. Chrome and Firefox both eat battery like crazy. Firefox worse than Chrome, but either will take a couple hours off your battery life versus Safari. And running lots of heavy JS tabs or "apps" will do even worse. Not that that necessarily has anything to do with the differences you're seeing in particular, just worth noting. Wrong browser, 20-30% worse battery life. Wrong site open in some tab in the background, 30-60% worse battery life. The overwhelming majority of what takes my Mac battery life from 8+ hours to 4 or less is Javascript or some heavy Java IDE or something. User software that gives a damn about how much power it uses makes a huge difference, well outside of just "don't run video games on battery power" and other obvious stuff.
