1、从log中看 [ 139.658736] dpm_run_callback(): platform_pm_suspend+0x0/0x58 returns -16
[ 139.658744] PM: Device alarmtimer failed to suspend: error -16，是由于alarmtimer 影响进入睡眠，连网同步下时间功耗就正常
2、时间同步后，自动息屏，非按power键息屏。[11:29:18.837]收←◆[ 429.656231] Restarting tasks ... done.
[ 429.676628] Abort: Pending Wakeup Sources: event1
[ 429.681631] PM: suspend exit ，log中显示event1会影响进入睡眠，该问题是硬件问题，硬件已知晓该按键会影响自动息屏问题,也会影响进入休眠造成功耗高，但长时间5分钟后可以进入8ma电流
