I have noticed an improvement to battery life with the latest update, but I can't yet say how effective as my reading habbits have changed since I was made redundant a couple of weeks ago.
As for the accelerometer, I turned mine off first thing, and I used to get the low battery life people were reporting. So I am just waiting to see how I do with the new firmware.
One thing I do know, is if the .xhtml files in the ePub are too large, it takes longer and longer, and uses more battery life to open the pages deeper into the file. Using software to change those to smaller file sizes (I use Sigil on OS X) makes a drastic difference.
