AIFF and battery life

So really, I searched a lot in this apple discussions for info on battery life if used with lossless audio and not found anything. 😟

I guess either noone really measured or apple facilitates this info to be concealed.

The iPod classic has a 32MB buffer so it will be spinning up the hard drive for every 32MB (about 1 song in aiff) it has to load and battery life will be a lot shorter than using smaller AAC/MP3 files (~4MB-6MB each).

You didn't look hard enough.

Thx for the link, but... it is the info that started me on my question. Common sense about compressing music to best for the battery life! HOWEVER, my question is: What is the battery life is if only lossless music is played?

Apple has not described what the battery life is with lossless.
Also, Apple Lossless is ~60% the size of AIFF/WAV, so battery life would be better with Apple Lossless than AIFF/WAV.

Test is yourself.
Add one song in a lossless format, fully charge the iPod, set it to repeat that one song and time it.

Yeah, I was thinking that lossless should drain battery something like playing a video, though no backlight. The best way is to get an iPod and really test it, since no data seemsto be available.
