Default I have just finished a battery test on my S9...

I have had the S9 for a week and it has gone through 3-4 charge cycles. Playing music at 192kbps for about a couple of hours and then deciding to test the battery life, I stopped playing the 192kbps tracks and began playing 128kpbs (a quarter of the battery had dropped by the time I started playing the 128kbps tracks). The screen was off, volume at 14, eq set to normal. I got 40 hours of audio playback out of the player. I am happy with this, but was wondering if I shouldn't be, and if my unit is defective for not giving me closer to 55 hours of battery life?

Most manufacturers exaggerate with their battery lifetime results. They're made under lab conditions, usually (meaning 128k MP3s with no EQ/BBE and backlight off) - 40 hours seem quite good to me. I'm getting about 35 hours out of mine with LAME -v0, my EQ settings, and a lot of turning the screen on and off.

40 hours is good. I've only ever seen one DAP(Sony NW505) get better than the manufacture suggest battery life, and wow it had some battery life(65 hours tested by me).

I heard these conditions apply with no Audio optimisations and screen brightness of 4, I've got mine on 3 and usually get quite alot of hours out of it, recharge it every week.
