Pretty straight forward and simple, why the hell does the screen need to light up every time I get a notification? On average, when you get a notification from any app, the screen stays on for at least 5 seconds then fades away and shuts off. You can see how this affects battery life already constantly waking up the screen. Say if my phone's down or in my pocket, its just unnecessary drain, why don't we have a option to not have the screen turn on every time for notifications, even if its just one single one? Do you all get my point here? Every notification you get on a iOS keeps the screen on for at least 5 seconds, so like example (Melissa has liked your photo) boom the screen stays on for at least 5 seconds and you can see how this adds up quickly. Say like your popular on Instagram/Facebook and get social notifications alot, or in a big iMessage group chat with friends, or just use your phone and have bunch of notifications that come your way every day, the screen stays on ALOT actually and that actually drains the hell out of the battery, there should absolutely be a option to not wake the screen when you get notifications. I estimated that say if you get lets say about 50 notifications in one hour (you put up a picture on Instagram and its getting a bunch of likes and stuff like that, whatever, anything) over the course of the hour, your phone's screen has been on for over couple of minutes without you using your phone at all in that hour(if you weren't using the phone in this case for a bit) and that's a pretty dam good battery drain on the iPhone's not really big battery.
