explain yourself.
the battery life is less with lossless?
woe is me.
oh..woe...woe..is me
Well, the battery life for the iPod is based on 128kbps file. This is important, because the iPod needs to read data from the HD and then put it into its internal RAM (32MB buffer, I think).
A 4-minutes song at 128kbps means around 4MB for the file. Which means the iPod can spin up the HD, buffer 8 songs, then stop the HD. That's why there's a delay when you skip "next track" too fast (the iPod has to reload since you skipped over songs it had already buffered).
Now, a 4-minutes song in Apple Lossless means around 20MB for the file. Sure, the iPod can put a bit more than one song in the buffer, but this buffer will get emptied pretty fast, so the HD runs about 5 times more often.
And the HD is probably the main thing that kills the iPod's battery (not sure the % of the power required for the HD vs the other parts though).
So, in the same general idea, the battery will last more for 128kbps than 320kbps, but will last a whole lot more if you used 64kbps, etc.
