How does flight mode impact push notification reception?

Everything you wanted to know about the impact of flight mode on the reception of your push for both OS.

Notifications are not received when the device is in flight mode (except when Wi-fi is activated). However, once this mode is turned off, the pending notifications may be delivered to the user, depending on the OS:

On iOS

After flight mode is deactivated, only the last push sent will be received. This is the behavior of the Apple / APNS push API, and does not depend on Batch.

If you want more information, see the technical documentation here.

On Android

By default, Batch offers the same behavior as iOS, but you have two ways to control it.

1. Via the "Collapse Key"

On the dashboard, you can ensure that all pushes are received:

• From the Creation Campaign Form > Advanced Settings > Disable the Collapse Key:

• From the settings of your Android app > Push Settings > Default Push Settings > Disable the Collapse Key and click on the "Update Push Settings" button:

2. Via APIs

You can set up a specific behavior or a mix of different behaviors, for instance:

• All the notifications are kept and will be delivered

or

• All the transactional pushes are delivered, but only the last marketing push is delivered

If you set up a TTL on your push or in your app settings, if the push is not sent in the fixed limit, it will never be sent.
