Android电池信息获得问题

之前有写过一笔记，但后面发现是错误的，感谢之前帮我指出错误的博友！

设置应用的：PowerUsageSummary.java文件，会判断：if (mPowerProfile.getAveragePower(PowerProfile.POWER_SCREEN_FULL) < 10)即亮屏时的功耗。这边主要通过：power_profile.xml 进行配置，默认配置是一个很小的值，如0.1mA,而实际配置正常后，如屏亮度为：300mA,此功能即可正常。更详细的内容，请查看：power_profile.xml
的注释说明。

<!-- Most values are the incremental current used by a feature,

in mA (measured at nominal voltage).

The default values are deliberately incorrect dummy values.

OEM's must measure and provide actual values before

shipping a device.

Example real-world values are given in comments, but they

are totally dependent on the platform and can vary

significantly, so should be measured on the shipping platform

with a power meter. -->

<item name="none">0</item>

<item name="screen.on">0.1</item> <!-- ~200mA -->
