After a day with the #Purism5 I can say it can successfully makes and receives voice calls and can receive SMS messages. I'm kind of sad the chat program closes xmpp conversations & group chats when you exit the app though.

Also several design decisions for android & iOS make more sense.

I tried using the Tuba the new gnome mastodon client on the phone, but even when i closed the application window there was still a process running in the background eating precious battery power.

On the purism you rapidly learn "if you're not using the app, make sure it's terminated."

And then I was like oh yeah, android apps keep begging me for the "run in the background" permission.

So now I'm giving my linux apps the side eye and wondering "do you actually need CPU time if your window isn't visible?

The #PinePhone seems to have achieved better battery life by being really aggressive about suspending the main phone CPU, but they have a great deal of control over the modem so as to better trust it to wake the phone CPU up if something "important" happens, like getting a call.

But that's level of suspend is marked "experimental" on the Purism's OS.
