Multiple days of idle with Phosh on pmOS, for one anecdote.
Wake-up on notifications is still a WIP AIUI, though.
I recently got back to mine with a fresh install and a lot has improved since last year.

Read up on PINE64's return policy, maybe; check whether your current phone network is compatible and decide whether you could live with the available applications. Watch some videos and decide if you can live with the time Firefox takes to launch and a lack of notifications. Make sure to have the willingness and time to tinker, to get the deeper "Linux knowledge" necessary if you don't have it, to make whatever distribution you start with your own [...]"
...so, to sum up, if you want a nerdy toy to tinker with, get a PinePhone. If you want something that works "out of the box", go look somewhere else.
That said, it does not have to be a lot of work for basic functionality these days in my experience - e.g. postmarketOS 22.06 is a solid base.
With some differences (better in some way, worse in others), it feels at a similar stage to desktop Linux on commodity hardware ca 2000~2005.
Both GNOME and KDE seem surprisingly serious with their mobile efforts but unless you're happy with a mostly console experience it's probably at least another year or two until basic apps like e-mail are in place for non-enthusiast non-tinker users.
As for distros, I am yet try try Mobian but other than that postmarket is the most reliable experience right now so far (Danct Arch may be catching up though :))
