Push notifications to me is one interesting addition to the iOS 8 update, it display pop-up messages from your apps, even when you don't have them open. Push notices help apps alert you to incoming messages and important announcements and also gives new users tips on how to get the most out of their iPad.

But the negative part of is; It interrupt your work, cause alert noises to play, even while your iPad is locked. Apps using Push can also drain your battery. If you don't want to be overloaded by notifications that you don't need, you can turn it off for individual apps or disable them across all programs temporarily with Do Not Disturb mode.
