For instance, the exact same OS install/SSD on my razer laptop vs thinkpad can draw either 4W or 7W. In this case, I believe a lot of that difference comes from the display technology in use, as the razer blade 15 display draws a fixed 3W even with brightness at 0% and the thinkpad does not.
I’ve created a graph showing what I believe to be the range of realistic battery life. The power draw will be affected by both hardware and driver optimizations, as well as the software running on the machine. For instance, my Razer Blade 15 will draw 10-15W on windows, but draw 7W on a custom and optimized install of Linux. I start the graph at 4W because that’s what my Thinkpad T470 draws with my optimized linux install, and it’s difficult to get lower than that. Technically I’ve seen it drop …
@Adrian_Joachim I found where I recorded this number, and it appears that 3W may have actually been for my old Razer Blade 15… but I distinctly recall measuring this on the FW16. It’s possible I’ve been mistaken, FYI.
