Just wondering why some apps are running in the background tasks and claim they need this to receive some information.
WhatsApp for example says:
When enabled, WhatsApp will retrieve messages in the background.
As far as I know those messages are received via push notifications so there isn't the need for background tasks since they do not update anything else (as of March 2014).
So my question is if I disable background tasks the push notifications will still work?
What about specific case of WhatsApp?
