Looked up up "Power Consumption Breakdown on a Modern Laptop" by Mahesri et al. and "Component-wise energy breakdown of laptop" by Kothuru et al. on Citeseer. According to published research from 2005 and 2010, with vintage laptop processors (which were more energy hungry than ones today), you can't get 50% more battery life by even if you eliminated the CPU power usage entirely -unless you're running a CPU pegging benchmark all day. Probably Intel marketing managed to fool the reporter into translating CPU power efficiency changes into battery life increases.
