Does Rockbox charge the batteries more/less/worse/better than the original firmware?
A3: Player: Rockbox doesn’t affect the charging on Players, it is all done by hardware logic out of software control. Recorder: The whole algorithm is made to carefully charge the batteries full and keep them full after that with a trickle charge option. Many documents about charge ICs were considered. If you want to know details, then look into docs/CHARGING_ALGORITHM. If you have comments, write to the Rockbox mailinglist.
