See how I introduced your case later with "Alternatively"? You saw it since you quoted me.

Fine, your email app works well in fetch mode. It took you three roundtrips to mention your actual setup despite having been asked about it quite early and despite it being a critical element in this discussion. Omitting to mention that doing this choice, your notifications are delayed.

Fetch mode is totally a valid choice, email doesn't need to be real time for every one. It will actually save battery life from what I can read: you don't need constant polling. Of course, push notifications are for real time stuff. What costs battery life or requires a push notification service on current widespread mobile devices is timely notifications. I can't help you if you fail to see how this can be useful, even if you don't personally need this or are against the idea.

Your email case is simply irrelevant to the discussion, but you made sure we couldn't notice until now.

You don't seem actually curious or interested in the topic at hand, preferring to show contempt and spite to people discussing with you here. Bu the way, frankly, loose the scare quotes, they are ridiculous.

I'm not sure what you are trying to achieve. If you hope to convince people that they should avoid them too, let me suggest that it's a terrible way of doing this. You seem to be here just to brag about how you don't need push notifications. Or to make fun of us. I flagged you, and I'll stop here.
