I've had plugins (ie: flash) disabled on Chrome for the last couple of years. Chrome still destroys my battery life.<p>In so far as I can tell, the act of scrolling in Chrome is either deeply CPU or GPU intensive, IIRC because of some optimizations they made for pages with excessively long content.<p>Using Safari rather than Chrome improves my battery life by anywhere from 2 - 4 hours on average. With no flash ever involved.
