Battery life
Elias_Maluco:
Hmm, makes sense. Thank you for the tips. Also, I was listening in full volume yesterday, that also might shorten the battery life, no?
Elias_Maluco:
Self repply: I turned off some effects, like the play/pause fade, the backlight fade, the eq, set the database to load from ram, and now the battery seens to be lasting a lot longer.
Also, I looked that 'battery capacity' setting in the manual and there it says that value is used to calculate the remaining power at the battery. But how do I know that my battery is actually 400 mAh? I dint found any mention to it on the iPod manual or even on the technical specifications on Apple site. What if the battery is actually bigger or smaller than that? Then the rockbox battery meter would be wrong, correct? How do I find the exact capacity of my battery?

The battery percentage shall always be right. It is the estimated runtime which is scaled based on the "battery capacity" setting.
Llorean:
Note: "Shall always be right" does not necessarily mean "100% correct" as much as "it is unaffected by the value you set for capacity, and is entirely affected by some hard-coded presets that won't change with what battery you use so there's no case where a user need edit them unless we've simply not calibrated things properly yet"
Elias_Maluco:
Ok I got it. By the way, battery life does not seens to be so bad here anymore. The thing is on for almost 10 hours now and according to the meter there are still around 30% left.
