With that backdrop in mind, we teamed up with the Wirecutter, a product recommendations website, to run an array of tests to determine best and worst practices for preserving battery life on smartphones. For those who still need extra juice, the Wirecutter also picked some external battery products.
了解了这个背景，我们与产品推荐网站the Wirecutter联系，做了一系列实验，找到为智能手机省电的最好办法。对于希望额外电量的人，Wirecutter还提供了一些充电宝类的产品。
The results showed that some conventional beliefs about extending battery life — like turning off Wi-Fi or shutting down all your phone’s apps — produced negligible or even harmful results. The Wirecutter also found plenty of helpful practices to get more use out of your battery, like playing music stored directly on the device (instead of streaming it) or tweaking email configurations.
实验结果表明，某些传统的省电方式――诸如关闭Wi-Fi或关闭手机应用――被证明没有用处，甚至是有害的。Wirecutter还发现了很多有用的做法，可以更经济地使用电池，比如把音乐直接存储在设备里（不要用流媒体收听）或优化邮件设置。
The Wirecutter tested a range of recent Apple and Android smartphones with the latest operating systems in tightly controlled environments. Your phone’s results will vary depending on the phone model, cellular carrier, location and other factors, but the general results should hold. Here are eight tips and seven myths busted by our findings:
