This time, however, I have left it sleeping for 7 days, the first "leave it sleeping and wait for the battery to run down" cycle since I installed 2.4.0. I got busy and forgot to check it on the third day. I didn't check it until today, the 7th day. It reads 90% charged still. Seems the new FW made a difference with battery power with mine. I understand that without calibration the battery meter may not be accurate but calibration or not it died in 3 days on sleep mode and now it's gone 7 and shows mostly full... something has improved somewhere.

That's very weird indeed! Did you change anything else apart from the firmware? Did you leave it to sleep from the home screen (so, without it having a book in memory)? If so, I think that might be why the battery didn't drain so fast. I'm suspecting there to be something going on in sleep mode when a book is left open (so putting the device to sleep right from the book without going to the home screen first). I'm going to test that right after my current test with kepubs finishes.
Putting the device to sleep with an epub open so far has got me 3-5 days of battery life. Now, with a kepub open instead of an epub, the results started out the same, very bad:
Code:
4 Mar 2013 10:18 100% kepub, sleep
4 Mar 2013 16:46 100% on, sleep 6h 28m
5 Mar 2013 00:02 82% on, sleep 7h 16m
5 Mar 2013 10:35 62% on, sleep 10h 33m
5 Mar 2013 22:35 49% on, sleep 12h 0m
6 Mar 2013 09:29 48% on, sleep 10h 54m
6 Mar 2013 11:43 44% on, sleep 2h 14m
6 Mar 2013 22:32 43% on, sleep 10h 49m
7 Mar 2013 09:19 43% on, sleep 10h 47m
7 Mar 2013 16:23 0% nothing 7h 4m
But somehow the last two days the battery has decided to hang round 43% without dropping as much as it did. Weird. Still though, estimating 5 days of battery life (instead of the initial 3.3 days), which is better but certainly not what it should be.
Edit: added the last line to results. Apparently the hanging around 43% was all nonsense as it gave up soon after, leaving me with 78 hours (3.3 days) of battery life, sleeping with a kepub in memory.
