    How much more quickly do larger files/songs (about 80 MB or so) on the iPod drain its batteries, compared to small/regular files (like 5 MB)?

    All other things being equal, there should be no difference. There's a fixed-size buffer that data gets put into from the hard drive, and it plays that data until it runs out and needs to refill the buffer.

    What might actually make a difference is the quality/bitrate of the audio file. A high-quality song would take up more data than a low-quality song, so if it plays a lot of high-quality songs, it'll have to refill the buffer more often. That would increase hard disk usage, which would in turn drain the battery faster.

    So is what I am talking about only affecting older iPod models?

    bingo, lossless uses your battery quicker causes it refreshes the buffer 4-5 times at least during a song, really long songs at low bitrate are all as normal

    I use mostly Apple lossless on my iPod (3G with a new battery). The run time I get is about half what was advertised on my new battery. (Before the battery, I would only get about 2 hours tops, now I get about 5.)

    Did you know that you can RENT CDs in Japan?
