I also got a Beepberry (which arrived as a Beepy, so I should probably stop deadnaming it) and I generally concur with your analysis. I'm definitely not getting anywhere near the top end of the projected battery life scale with a Pi Zero 2 W installed, nothing much useful fits on the display, and I have to sit under more light than I'd like hitting my eyeballs to read the screen.
Incidentally, there exists now a functional analogue - complete with scavenged BB keyboard - sporting an ESP32 and a backlit screen in place of the Pi0 and memory LCD: the Liligo T-Deck. I don't need one, and I won't write software that runs on it, but I still want one because cute LoRa thing.
