60秒科学:App IDs Other Battery-Eater Apps


60秒科学节目(SSS)是科学美国人网站的一套广播栏目,英文名称:Scientific American – 60 Second Science,节目内容以科学报道为主,节目仅一分钟的时间,主要对当今的科学技术新发展作以简明、通俗的介绍,对于科学的发展如何影响人们的生活环境、健康状况及科学技术,提供了大量简明易懂的阐释。

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.

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.

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.

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.

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