My favorite comment from TFA: > None of your math makes sense. All your measurements have only the consumption at one exact instant, not over time, the total energy used is the integral of the energy flow over time. You'd need to measure the consumption over time, or total discharge of the battery, to actually have the energy used to load a page (in J, not W, you can't measure the energy required to load a page in W)…
Everyone's dodging the point of the post (versus the exact numbers and terminology). As I said on reddit as well: > The issue is that the redesign uses more power across millions of devices, and that has an impact. > I might have gotten the exact number wrong, but the exact number doesn't matter that much. It's about it being a significant difference.
Of course the exact number matters. Let's say you're off by a factor of 1000. Then the power difference isn't really worth worrying about.
