But the PinePhone is none of this: terrible phone quality, the modem on my device is unreliable, the autonomy is okayish. I also had a PinePhone Pro that died: big improvement except the autonomy was much worse and it would strongly eat. I believe that's what killed it, actually.
With good hardware, I would be happy with a Linux mobile OS. But I don't use WhatsApp, I don't have a banking app, I don't pay with my phone, and have no proprietary app in general.
Things like Wi-Fi calling would probably not work neither, but I don't have this with my old Android phone neither.
You will have to hope mobile alternatives to Signal will work well enough for you too (and I guess that requires liking some adventure, but if that works, you also win on not being limited to one phone per Signal account).
You mention autonomy a lot, and I agree. I don't think it's a question of hardware: I can install Android on my PinePhone and see that it uses much less battery than a Linux system.
Android was built for that: it is extremely optimized for battery usage. I think it will be very hard to beat that with Linux.
But I'm willing to believe that Linux mobile can improve a lot.

Did you and what did you manage to achieve? I could reach 1.5-2 days of light use with mobian.
While I think it is cool, I am really wondering if there is a future with the idea. If the goal is to run Android apps through Waydroid, then I may as well run Android. If the goal is to be more private... well I think AOSP-based systems like GrapheneOS are in a better position because they get the Android security model.
The cool thing about running Linux is the freedom, but honestly I generally don't need that on my phone. On my phone I want the mainstream apps that allow me to connect with friends and family (yes, that includes WhatsApp and Signal). It quickly ends up being a fancy RPi with a screen and battery (and tons of sensors that probably won't be useful), but then I can actually go with an RPi and SSH from my laptop (I think such server projects suggest removing the battery anyway).
This said, I truly admire all the mainlining work that the PostmarketOS contributors are doing. This really helps everybody, including the AOSP-based Android alternatives.
If you want to ask more questions and this site has some way to message me with notifications feel free! I've been using this Pinephone for at least over a year or 2. Random aside: Don't use an SD card as a boot/main drive. I got a 256 & 128 gb SD card that are read only now..
Unless you have one of their handful of (obsolete) blessed phones and pay them money for the privilege, you can't use their stuff.
I get that they're effectively a startup spun out of Nokia, and that they'd rather sell value than give it away. Still, non-Android Linux for touchscreens is in a sad state. Having one of the only options locked up where few people can try it and nobody can contribute to it makes the ecosystem worse.
There's gotta be a better solution to raise all the boats than get a handful of enthusiasts with old Sonys to pay them $30 each.
Personally I like having Linux on the phone a lot for other reasons as well. For example, last summer I was backpacking in North America for several weeks. At some point I realized that I'd really hate to lose the photos on the memory card of my DSLR. Instead of getting another card and hiding the first one somewhere "theft-proof" in my belongings, I just went to BestBuy, got a memory card reader, plugged that into the phone, mounted the memory card filesystem and rsynced the files home over my vpn - which is exactly what I would have done if I had my laptop with me. Sure, I probably could have figured out a way to achieve something similar on Android as well, but having all the familiar tools available made it so much easier.
I preferred SailfishOS on my Jolla Phone (and my Jolla Tablet) as the experience is much better with how you can access files on the file system etc. But for various reasons (including a cracked phone screen) I went back to Android several years ago.
