Isn't the whole thing missing the point?
I mean, really, when's the last time you were concerned about which browser to use because you only had 6 hours of battery left if you used Chrome to surf, instead of 7 if you used Edge?
Um, no. In previous Chrome builds (<53) it would spin laptop fans endlessly even when nothing was going on and use at least 50% CPU, at close to max freq. Battery life was significantly worsened just by having Chrome open. So when was the last time I was concerned about battery life due to which browser? A couple of months ago it was a real problem. Now they're close enough that Chrome is usable, because it's so much better as a browser and only a little worse on the battery.
