What does Apple Push Notification Service do?

Apple Push Notification service (APNs) is a cloud service that allows approved third-party apps installed on Apple devices to send push notifications from a remote server to users over a secure connection. For example, a newstand app might use APNs to send a text alert to an iPhone user about a breaking news story.

Can I disable Apple push service?

iOS enables you to both disable push notifications entirely, or turn them off for individual apps. To access iOS notifications settings, go into the Settings > Notifications menu. From that list, you can configure each app's notifications settings or disable them.
