@chunkystyles @rozlav The boot time is indeed kind of annoying. Seems like there ought to be some way to save a memory image, and reload it on startup, and avoid a proper boot.
I just got a pi zero 2w, and read somewhere that they boot faster than the v1 pi zero. We'll see.
But the solution may just be to have a decent battery, and try not to let it ever get to 0%.
