科学美国人60秒 系统能检测出耗电应用程序（在线收听）

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.

大多数智能手机充满电会帮你度过一整天。只要你远离那些编写的很糟糕的软件，不要用那些软件不停地连接网络，不要给处理器带来沉重负担。

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.

但是哪一类应用最耗电呢？加州大学伯克利分校和赫尔辛基大学的一个研究小组跟踪苹果用户和安卓系统用户来研究这个问题。

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.

对于苹果的iOS系统，音乐软件是该系统最受欢迎的应用程序，但是交通和导航应用软件是最耗电最快的应用。还有一些最耗电的安卓应用程序是黑衣人3游戏和泰为公司的导航器。

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.

研究人员通过一个由他们编程的免费的耗电跟踪应用程序——克拉，得到的这些软件的耗电数据。当然，这款克拉软件并不是唯一的一款耗电追踪应用程序。但是由于这款软件被参与研究的研究对象们下载了超过100万次，所以克拉帮助研究者针对每一个操作系统，创建了一个关于最耗电的200款应用程序的图表。

Now if they could just come up with an energy-efficient app that keeps the big new iPhones from bending.

现在，如果他们可以为新的大屏苹果手机开发出一款节能应用程序防止弯曲就好了。——拉里·格林迈耶
