For vibration: more specifically only the alarm clock works correctly. All others, like touch feedback, notification and ringing, hardware test, etc doesn't work when the phone is not charging.
Has anyone encountered this strange behaviour like me?
update: I found out this is caused by battery saver in developer options. It will be helpful to display some info about the battery saver mode when it is enabled, as everything still works fine in my previous phone even when saver is on.
