计算机器人传感器的功耗 [英] Calculate Android sensor power consumption

问题描述

<一个href="http://developer.android.com/reference/android/hardware/Sensor.html#getPower%28%29">getPower()返回所使用的传感器毫安的能力，同时在使用中：

getPower() returns the power in mA used by a sensor while in use:

现在，我需要计算多少电池所使用的传感器的登记

Now, I need to calculate how much battery is used by the registration of the sensor.

难道他珍视getPower（）返回表示毫安（每小时毫安），或者其他什么东西？ 如果是的话，有没有办法让电池毫安，以计算所使用的传感器电池的％？

Does he value returned by getPower() indicate the mAH (mA per HOUR) or something else? If yes, is there a way to get the battery mAH in order to calculate the % of battery used by the sensor?

推荐答案

东西很相关的已在谷歌集团不久前讨论。你可以找到href="https://groups.google.com/group/android-developers/browse_thread/thread/6069056189b02d29"这里仅供参考rel="nofollow">全螺纹的

Something quite related has been discussed in Google groups not too long ago. You can find the full thread here for reference.

这是在该线程的最后答复，这应该回答你的问题少量摘录或多或少的：

A small excerpt from the last reply in that thread, which should answer your question more or less:

（...）电池容量总是以毫安计给出。 （...） 什么   事项是多长的电池可以提供给定的电流在其   额定电压。 3800MAH意味着它可以提供3800毫安1小时。   认识到这一点很有道理，现在的API是提供当前   漏极作为功率消耗的量度。现在，您可以计算出有多少   实现它将会对电池的寿命作为时间的函数。

(...) the battery capacity is always given in terms of mAH. (...) What matters is how long a battery can supply a given current at its rated voltage. 3800mAH means that it can supply 3800mA for 1 hour. Knowing this it makes sense now that the API is providing the current drain as a metric of power consumption. You can now calculate how much effect it will have on the battery life as a function of time.
