That's correct.

Thankfully all mentioned codecs are well below 90% CPU-time consumption
and despite Rockbox having no fine-tuned power-management it gives about
8-10 hours of playback for all formats on e.g. the iPod Nano
(http://www.rockbox.org/twiki/bin/view/Main/IpodRuntime), while
according to Wikipedia this device is supposed to have a battery
lifetime with the original firmware of about 14 hours for audio
playback. It appears entirely possible that with proper power management
and optimized decoders for a specific hardware platform the gap may
close, but that's something to be determined by the engineering department.
