Android devices ignore this field. ## App setup in Xcode Before using background pushes, your app must enable **Background Modes → Remote notifications** in your app’s Xcode project. Without this, iOS will not deliver the background pushes. ### Delivery behavior - Background pushes are not guaranteed. - iOS may delay, merge, or drop them depending on battery, device state, or push frequency. - Avoid relying on them for real-time guarantees.
