cpu功耗与电压一直不降是个阴谋

IOS（你说的MAC系统）和windows差一倍，那suse、red hat、debian、ubuntu这些系统和
windows相比呢？

不用比较其他操作系统了﹣﹣苹果新版OS X山狮（升级到10.8），电池续航时间只有上一版本的62%，估计是这个版本还没优化好。下面是老外的测试结果：
Our own testing revealed similar (and significant) drops in battery runtime after installing Mountain Lion. In previous tests, we were able to regularly achieve just over 8 hours of use by relying solely on our Retina MacBook Pro's integrated Intel HD4000 GPU. Performing the same "real-world" test using the same software applications and usage pattern, we never got the Retina MacBook Pro to run for more than a few minutes past 5 hours after a full charge.

看了这么半天，没看见你的证据呀，既没有图表，也没有引文来源。来点干货吧，我们都
眼巴巴地等着呢

仔细看上面苹果山狮OS X的例子，即使是以优化能力著称的苹果，在没有优化好代码的情况下，也会导致功耗增加的——新版本的电池续航时间只有旧版本的62%
