I just made a post about my observation of Lion's new power management feature. I would really appreciate anybody confirming these changes (I'm running 10.7.1) and providing your Mac model and battery percentage when testing. I ask for battery percentage because it effects how iPhones are charged using USB from a Mac, so it's not out of the question that remaining power would effect the characteristics. I need feedback and other experiences before I make the post public. Thanks all!!!
