Comment How many runs? (Score 2) 57
How do they run these experiments? I don't see any deviation in the measurements. It'd be nearly impossible for the thing to run exactly for 3h55m every time. It should probably be given as 3h55m +/- X minutes.
Also, do they swap laptops to eliminate innate differences in batteries between the machines? Say laptop A running Chrome dies after 3h00m and laptop B running Edge dies after 3h10m. Do they run the test again with laptop A running Edge and laptop B running Chrome and get the same results? Do they repeat the runs on different laptop models?
