How do you measure power consumption on a Mac? I'm using a 15" 2015 MBP with ~4h battery life, even when the battery was new. I'd like to see how the upgrade affects this.
I don't about precise power measuring tools, but I use CoconutBattery which displays what my current drain charge is. I already know what the values are when "idle", so I can compare the new values on Mojave with the ones I remember.
