Well, I went ahead and got one the other day so I'm in the process of setting things up...

I'm going to apply a WPS with album art and then do something like play a mixed of Oggs and MP3s in normal and then shuffle mode to see what happens. Just to simulate "normal" usage :)

Good idea! Make sure to post your results when you are done testing.

Does it really make a difference even though the Sansa does not yet support frequency scaling and things like that?
I'm just curious since I thought that an idle CPU drains as much energy as a working CPU when running at the same frequency.

Unfortunately my battery bench test didn't work properly.... Must have done something wrong since the file was empty. Anyway I can still describe what I did,

Settings,

* Backlight off
* Volume ~15db (can't be 100% sure)
* AquaDock WPS
* Playing a directory of 300 MP3s and OGGs (192 average bitrate)
I put my Sansa on to play yesterday morning at 8:30am just before I went to work.  I came back in at 6pm and took a look at the player... it was still going! Pretty good.

I left it for a little longer and kept checking it. At 9pm it was still playing. Around 9:30 I fiddled with the player and put the backlight on so I could see what it was playing. I put the brightness on low.

At 11:30pm it was STILL going. I left it overnight so don't know when it finally stopped.

Overall I was very impressed with the battery life... I was expecting it to have died when I came in after work.

To conclude the Sansa lasted for over 12 hours with the backlight off and playing a bunch of MP3s and Oggs at ~192kps

I'll use it over the weekend with the WPS and brightness on low and see how I go from there.

Nice, trumps the Rockboxed Nano performance by nearly double perhaps.  I've just started using my Rockboxed Sansa regularly lately and have noticed I can go much further on a charge than with the Nano (6-8 hours).

It was the same when I tried to battery_bench my Sansa. The file just remained empty but I haven't found out yet what I was doing wrong. I did everything as stated in the wiki, played a rather large playlist and did not run any other plugins.
