I recently flash modded using the cheap green board, iFlash CF to SD adapter and a cheaper no name 64GB micro SD card. The battery life in Rockbox is terrible at maybe 2.5 hours while the original firmware gets about 10 hours. I am running a daily build from 8/22/23.
I'd really like to get this resolved as Rockbox is superior in so many ways. I have searched these forums and tried some suggestions but none seem to work. Please help.
