6-7 hours of browsing in Firefox, 4-5 hours when doing work involving occasional building/compiling, 3-5 hours of 2D native Linux gaming, 2 hours or less of 3D AAA gaming through Steam/Proton.
Luckily there are battery stats. On a 7840U with power-profiles-daemon installed and PCI power saving turned on (but not wifi or audio power saving, or VM writebacks, I don't feel those are worth the power savings), it draws 3W if I'm doing absolutely nothing with the screen on its dimmest setting (I mostly use the laptop in bed at night), and 5-11W while web browsing on Firefox.
It goes up to about 13W while watching youtube, even though it claims hardware accelerated video decoding is on.
well it's new battery feel so far, just got the machine less than two weeks ago. Haven't done any long battery-related work yet. My previous Dell XPS13 had the battery puff out and it actually wrecked the mainboard in doing so, so I'll be watching out for any negative experiences like that here, that I can open the machine right up in 30 seconds to attend to issues like that should be a plus.
