adb shell reboot -p to shutdown the phone.
Note: All the following commands below require root access.
On Android Oreo, this works and does a graceful shutdown:
adb shell su -c 'am start -a com.android.internal.intent.action.REQUEST_SHUTDOWN' adb shell su -c 'am start -n android/com.android.internal.app.ShutdownActivity' #alternative; the aforesaid intent is supposed to be passed to this component under normal circumstances, but calling the component alone works too adb shell su -c 'svc power shutdown' # alternative; tested on Android 5.0, 6.0.1 and 8.1.0
Following is an alternative and is tested on Android 4.2, 5.0 and 6.0.1. I do not know about Nougat but it doesn't work for Oreo though.
adb shell su -c 'am start -a android.intent.action.ACTION_REQUEST_SHUTDOWN --ez KEY_CONFIRM true --activity-clear-task' # I kept this here for historical purposes only.
If you're running Android KitKat or above* and have root access, you can try this command:
adb shell su -c 'setprop sys.powerctl reboot,recovery'
* The last version on which the command is tested upon is stock Android 6.0.1.
here is an another method, go to android shell then shutdown the phone!
adb shell shutdown
To shutdown the phone use this command on PC:
adb shell halt
