Rockbox General > Rockbox General Discussion
iPod Nano 50% less play time.
saratoga:
We could test that theory if someone were to measure the power consumption with a DMM on the ipod at a few different clock speeds and no boost. Then we could figure out if the high power use is from high CPU use or from devices which are constantly bleeding off power independent of what rockbox is doing.
Probably easier to just work on the CPU nuse issue first though, since that needs fixing regardless :)

I think mp3 playing using many cpu without rest like windows.sleep(...); in the thread.

I think developers first must make low battery usage like in original OS, before any other daily changes, because nobody want using firmware with 2x less playback time.

On most other devices Rockbox runs on, it consumes less power than the original firmware, and obviously we want the same thing on the ipods.
However, battery life is not every user's #1 priority, as shown by the number of people who are running it on their ipod. If you only listen to music for 5 or 6 hours a day, and can easily charge your ipod overnight, then what's the problem?
Work _is_ being done to improve battery life on ipods, it's just a slow progress, and will be a combination of small incremental improvements and sudden breakthroughs. No-one can predict when we'll reach the same playback life as Apple's firmware does though.
Also, don't forget that not all the developers who work on Rockbox even own ipods - Rockbox is far more than just a replacement ipod firmware.

You are wrong.
