iPod Nano 50% less play time.

(1/4) > >>

Colombo:
Original Apple OS is 14 hours playing.
Rockbox is ~6-7. I think it bcuz mp3 player get more CPU time and so more battery power. Can developers make low battery use?

p.s. sorry, bad english.

Llorean:
'bcuz' is not a real word. Our forum guidelines require using real words. Please follow these rules in the future.

It's much more complicated than simply how much CPU time is being used. While it's being worked on, this is very well known, and is not likely to be an easy solution.

Colombo:
and what is debugging -> CPU frequency modification? What is boost ratio? How it influences on battery use? I set 30mhz and music became 3 sec play and 1 no play :D

Colombo:
rockbox is very good, many features etc, but simply playback time is 2x less than apple os. I must return back to apple os.
So when rockbox will be low CPU usage, notice it in main page :] thx

AlexP:
It is most likely not CPU usage causing the battery life alone, but likely a combination of this (solved through optimization), and perhaps some components not being turned off properly.  It is very hard to code for chips with no data sheets or public information available ...
