It's a hassle to always have to worry if they are fully discharged, so one less thing to worry about is good! > >You should definitely see longer run times at lower bitrates. It's tricky >computing EXACTLY how much longer. That got into WAY higher math computations than I want to do! But at least now I understand WHY higher bitrates use more battery power. It wasn't making sense to me before why the unit would care what the bitrate was; I was thinking in terms of a CD player, where I don't think it matters since the CD is always spinning anyway (is that right?). It makes sense that if it has a certain amount of buffer and has to refill the buffer more often cuz it holds less at 128 bitrate than at 32 bitrate, then the accessing the hard drive uses battery power. Thanks for that explanation; I love understanding the WHY of things! I actually can't tell that much difference in listening to an audiobook at 32 bitrate and 96 bitrate myself, so maybe I'll just reduce them and keep the higher bitrate as an archive copy. Learning more and more and getting happier and happier with my Jukebox! Thx!
