tl;dr: If the PinePhone is charging or the wifi is otherwise kept connected, email notifications come very quickly indeed.
Full story:
I've timed some notifications. My setup is: Geary logged into a gmail account via an app-specific password. PinePhone is on wifi only, not cell connection. PinePhone is running Mobian, not Postmarket. I consider the blue LED flashing to be the notification.
If the PinePhone screen is on, or if it is charging, then the time between email sent and Phone notification is 17 seconds plus or minus 1 second, indicating that it's actually faster even than the Android push notification!
If the PinePhone is not charging and the screen has been off for more than 5 minutes... the notification never comes. Presumably the wifi goes to sleep and doesn't come back up. This may be different on PostmarketOS, but on Mobian this is what I observe. Note that there are some user-generated hax to keep the wifi awake which may make this solution viable.
Note also a weird phenomenon in which, exactly 4 minutes after the screen turns off, the blue LED flashes for exactly 1 minute regardless of whether any notification is received. Again this may be Mobian-specific.
