4. Play downloaded music instead of streaming.

4. 播放下载音乐，而不是使用流媒体收听

The next tip may come as unwelcome news. nowadays, online streaming is the most popular way to listen to music, with services like Spotify, Pandora and Apple Music — but this method guzzles lots of battery power. In the Wirecutter’s tests, streaming music over a Wi-Fi connection for two hours used 10 percent of an iPhone’s battery reserves; streaming the same music stored directly on a device over two hours consumed only 5 percent.

这条提示可能不怎么受欢迎。如今，使用Spotify、Pandora和Apple Music等在线流媒体是最受欢迎的听音乐方式，不过，这种方式也损耗不少电能。根据Wirecutter的测试，Wi-Fi模式下，用流媒体方式收听2小时音乐，会用掉iPhone电池的10%；而在同等情况下使用下载方式收听，只使用5%。

Fortunately, streaming services like Spotify and Apple Music still let you listen to songs the old-school way: by storing the music right on your device.

幸运的是，Spotify和Apple Music 都允许你以传统方式收听音乐——把歌曲下载到设备里。
