简单的来说就是在电脑终端上输入下面的命令：

https://github.com/google/battery-historian

> adb kill-server

> adb devices

> adb shell dumpsys batterystats --reset

<disconnect and play with app>...<reconnect>

> adb devices

>adb shell dumpsys batterystats > batterystats.txt

> python historian.py batterystats.txt > batterystats.html
