1、getprop 这个命令可以用来查看当前安卓系统的各种属性。与之相似的还有setprop、watchprops等

2、start/stop serviceName 可以通过这两个命令来启动系统服务，关闭系统服务，但是关闭应用进程好像不是很好使

3、安卓查看电源管理状态

      3.1：检查userspace wakelock状态
      dumpsys power
      cat /sys/power/wake_lock

      3.2：检查kernel wakelock状态
      cat /sys/kernel/debug/wakeup_sources
      查看actvie_since列，大于0的会导致无法suspend

      cat /proc/wakelocks
