用Carat揪出APP中的“耗能大户”
More than a million volunteer users of the smarthphone app Carat have helped researchers identify those apps that really suck battery power in both the Android operating system and Apple's iOS. Larry Greenemeier reports

Most smartphone batteries will get you through the day on a full charge. As long as you stay away from apps that are constantly connecting to the network, are poorly written and put a heavy load on the processor.
大多数智能手机在满电的情况下可以撑一天，但前提是你不去使用一些需要一直联网的，或者编写得很差劲的、会给处理器带来很大负载的APP。
But which apps are battery hogs? A team of U.C. Berkeley and University of Helsinki researchers is tracking Apple and Android users to find out.
哪些APP是“耗能大户”呢？一支来自加州大学伯克利分校和赫尔辛基大学的团队对苹果和安卓用户的数据进行了跟踪分析，将它们抓了出来。
For iOS, music is the most popular app, but the traffic and navigation app Waze is the fastest way studied to drain your battery. Some of the most power-hungry Android apps studied are the Men In Black 3 game and the TeleNav GPS Navigator.
对于iOS系统而言，音乐类的APP最受欢迎，而导航类应用Waze则是消耗电量最快的一款APP。在最耗电的安卓应用中，游戏Men In Black 3和导航应用TeleNav名列其中。
The researchers got their data through a free battery-tracking app they’ve written, called Carat. It’s not the only app that does this, of course. But since it’s been downloaded more than one million times by study participants, Carat has helped the researchers create a chart of the 200 most power-hungry apps for each operating system.
研究人员开发了一款名为Carat的免费APP，以此跟踪记录手机的电量变化从而获得数据并加以分析。当然，不止这一款APP可以做到这一点。但是Carat的下载量超过100万次，庞大的数据量帮助研究人员分别找出了iOS和安卓系统中200个最耗电的APP。
Now if they could just come up with an energy-efficient app that keeps the big new iPhones from bending.
何时能推出一款节能APP，免得让巨大的iPhone 6手机“竞折腰”！
