Android手机app的adb命令测试电量

Android手机app电量测试

Android 5.0及以上的设备, 允许我们通过adb命令dump出电量使用统计信息

第一步：手机安装要测试的应用，打开手机开发者模式-USB模式，运行cmd.exe：

adb kill-server

adb devices //查看手机连接是否正常

第二步：因为电量统计数据是持续的, 会非常大, 统计我们的待测试App之前先reset下, 连上设备, 命令行执行。

adb shell dumpsys batterystats --reset

　　此时，手机里电量统计被清除，建议确定手机连接成功，多清理几次。而后再断开USB数据线，操作要测试的app相应的测试流程。

第三步：重新连接手机

adb devices //再次确认是否连接成功

//此命令持续记录输出，要想停止记录时按Ctrl+C退出
adb shell dumpsys batterystats > E:\batterystats1.txt

　　导出的统计数据存储到batterystats1.txt，我们可以在此文件中间看到电池的消耗情况：

　　Computed drain 显示的是总电量，Screen 显示的是屏幕使用电量，在日志的后面可以看出 Uid u0a723 是操作的应用，Idle 显示的是重定时器使用电量；

　　一般是  功耗的计算=CPU消耗+Wake lock消耗+数据传输消耗+GPS消耗+ Wi-Fi连接消耗

　　这次我测试的是 Screen + Uid u0a723 + Idle + Wifi + Bluetooth 的电量。

　　

注：这是我此次工作中的学习总结，后面持续需改完善。
