I read that on another thread, and was just wondering if that is correct |

Processing power, however, is not the only factor in this equation. Lossless files take up more space and thus will require the portable to transfer more data. On a HDD player, this will indefinitely use more battery life. But on a flash player, I have no idea how this will affect battery life. (1) Do flash memory modules differ in transfer rate? (2) If so, do different transfer rates draw power at different rates? (3) If transfer rates are uniform, then does full cache use draw more power? (4) How much power do the memory module and processor cache draw compared to the other components?
We could speculate all day, but real-world testing would save a lot of time. This poster found that DRM'd WMA draws ~43% more power than an MP3 on a Sansa clip, despite the MP3 being encoded at a much high bitrate. Anyone willing to do similar testing with their iPods?
