I see that the biggest battery killer for my phone is the "Home and Lock Screen" My screen lights up quite a bit and it's mainly because of notifications for my work Exchange account. I do like getting instant "push" updates because in the world of IT (my line of work) i really need that. However, I'd be willing to settle for just a sound (or vibrate if on silent mode) to stop the screen from lighting up every time. Is this possible? Maybe JUST have sounds when a new message comes in, but nothing in Notification Center or lock screen. Just a sound basically telling me I need to go into my mail app. Any suggestions are appreciated!
