研究发现有大约45%的电池消耗情况发生在屏幕暗的时候。许多电量不足是因为应用在后台更新——比如下载标题、更新天气,而事实上你根本没一直开着这些应用。
And different versions of the same app require different energy supplies. For instance, some versions of the Facebook app were twice as energy thirsty as other versions. So app version choice could slow your battery drain.
此外,同一个应用的不同版本对电量的要求也不尽相同。举例子说,有几个版本的脸书用电量是其他版本的两倍。所以说,选好版本也可以减缓电池消耗。
But one of the most hidden energy draws, zapping 12 percent of the battery, was just cellular paging: the pings from a cell tower every 1.28 seconds, that tell your phone if a call or message is on the way. Which is, ultimately, the price of being connected.
但最为隐蔽的电源消耗是蜂窝寻呼,可以用掉12%的电池,即手机信号塔每1.28秒就发一次的声脉冲,提示你来电或者有短信。这归根结底就是保持通信顺畅的代价。
