估计的电池剩余时间有误

检查剩余电池寿命时，您可能发现它报告的剩余时间与电池实际持续的时间不同。这是因为系统只能对剩余的电池寿命量进行估计。但是，随着时间的推移，估计会越来越准确。

In order to estimate the remaining battery life, a number of factors must be taken into account. One is the amount of power currently being used by the computer: power consumption varies depending on how many programs you have open, which devices are plugged in, and whether you are running any intensive tasks (like watching high-definition video or converting music files, for example). This changes from moment to moment, and is difficult to predict.

其他因素像电池如何放电，一些电池放电很快，没有准确的电池放电资料，只有一些粗略的剩余电量估算。

电池放电时，电源管理器将算出其放电属性并了解如何对电池寿命进行更好的估计。但是，这样的估计无法做到完全准确。
