A lot of snapdragon 845 phones tend to work fairly well no?
I'm not sure what the status of the newer devices is but those older oneplus 6/poco f1 era phones tend to work well with mainline kernel:

As far as I know, the camera barely works on any device, including snapdragon 845 phones. Now I'm not saying the snapdragon 845 is unusable as a daily driver, but it is getting a bit long in the tooth, especially since the majority of what you run on a phone is browser engines, and web sites and web applications are not getting less demanding over time.
