It's not murdering battery because it's "harnessing the full power of the CPU", it's chomping through almost 1% battery a minute on Mac while doing virtually nothing.
Apparently "vibrance" is one of the culprits and switching to the light or dark themes can help a lot. But yes, it's destroying battery compared to Safari for me. Which is a shame, as it's already my default on Windows.
