Apple

after creating one post here someone told me to turn on do not disturb mode but that completely deletes notifications. what im having problem with is that when some notification comes,it wakes my screen so it drains battery. what i want is for it not to turn my screen on but when i double tap the screen to see the notification there. is there a way to do this or not? turning DND and putting the apps as exceptions makes them work as if DND wasnt on so this doesnt solve it.
