rockbox have dual boot right? i can boot rockbox firmware and the original apple firmware..

if i choose to boot the apple firmware, will my battery life go back to 10-12 hours again? (i think it will go back to 12 hours coz the ipod is not running rockbox w/c is a battery hog) but im not sure though.. need your input.

Yes, Rockbox has dual boot, and as long as you run the Apple firmware, the battery life will be normal again. The battery will only be drained quicker when running Rockbox.

Well, I'm afraid I don't understand everything with ipod Battery, but indeed here are my results (sorry if they are misplaced) (Ipod 5.5G 30 Gb firmware 1.21)

- Using RockBox Release 20/02/2006 with following settings :

Hardware eq : ON - Low Filter +6db - high filter +3DB
Software equalizer ON
Sound level -11Db
no backlight

I do obtain 7H27 min of play using a 40 songs reference playlist (repeat and shuffle ON)

- Using same playslits (MP3 vbr 160 Kb) with full sound (my apple firmware is debrided to 115DB abd my MP3 has been normalized do 89 DB) and bass booster (no artwork)

I do obtain around 16h of play under Apple firmware (that is much longer than the up to 14H duration that apple indicates)

I only rebooted under Apple's firmware...

But I have to say, that except battery duration, My only regrets with RockBox firmware, is I haven't found a way to tune the click/wheel sensitivity...

Regards

I am currently getting 45 minutes to an hour out of my 5G 60 gig Ipod.  The original firmware is not installed as it got messed up when I was updating the bootloader.  I'm thinking of backing up my music and just formatting it, putting an album on and bringing it to Apple.  I know Rockbox has decreased battery life but it definitely seems like my battery is dying.

AlexP:
jeanlune: to do a proper test you should not have equalizer on, or anything else computationally intensive such as cross fading, replaygain, peak meters etc.  Apple's firmware does not do this, so the comparison is pretty meaningless as without these turned on, rockbox will also last longer (although still not near the OF).

DefineByte:
Replaygain is expensive? Isn't it just a simple volume adjustment at the start of each song?
