One thing I forgot about the horrible iOS notifications was screen wake every time, is there a way to turn that off and just get the the notification sound without draining the shit out of my battery?
I can't even imagine getting so many notifications that I would be concerned about battery life, maybe consider disabling notifications for some apps haha?
Other than that though, yes you can, it is app specific though:
