After trying a variety of things, the best battery I have managed is ~22 hours, with light use, everything sync off, minimal apps.
The cell radio still eats 50%+ of the battery. Even in airplane mode, checking the radio via terminal still shows it is on.
Is there a way to just kill the radio entirely? Flash a bad image, a kernel without a modem driver... anything? It never need work as a phone again, so I'm open to anything.
