You might have told earlier, but could you please share some details about your config? (Headphone, volume level, mp3 resolution, eq setting - if any). I'm just curious as I cannot get more than 57 hours out of my Plenue D... Thanks.

Thanks, it seems my suspicion was right after all. I'll turn it off as well, hopefully a firmware update will improve it. :-)

Right. It seems others were concerned about battery life too as I saw a few of us posted some results. I have too, while testing with the same 320kbps mp3 files on the same volume I usually listen to (14) on my IEM.   With music on external microSD: 57:01:08 With music on internal memory...

Never liked the case from day 1 to be honest, it's just not to my liking. Had a look at the screen protector at AMP3, but couldn't see how many of them are in a pack, and whether they are finger-print magnets like the current one my other half ordered me from Taiwan for $12...

I have the Plenue D for about 1.5 months now. I'm happy with the sound but noticed that the battery should last longer given my listening habit (about 3-5 hours a week currently). I'm going to do a test in the next week or so, that should give an indication...

I was about to ask the same. I still need to do a full test but I don't think mine last longer than 20-30 hrs either, listening to 320kbps MP3s stored on an external microSD card. :S (I use an IEM and volume rarely goes above 20.)
