Indeed; I have an original PinePhone (convergence edition) and the battery is not half bad while you are using it. I think the main issue has been poor software support for wake-from-suspend, which prevented the phone from saving power when not in use. I believe that these issues have been largely resolved in the latest versions of PostmarketOS, Mobian etc.
FYI, going to suspend / receiving calls during suspend / waking from suspend haven't been a general problem on the (non-Pro) PinePhone since 2021. You just have to make sure to switch to the FOSS modem firmware, and occasionally there are regressions (the most recent one being https://gitlab.freedesktop.org/mobile-broadband/ModemManager... ).
