I'm still on my first week of use.

After charging the device to 100% post firmware update, I've been using KOReader App for more than 3 hours of daily reading, 1 hour of it with backlight on (all wireless antennas off, battery save on).

After three days, battery is now on 65%, which I know is at least 30% better than before de firmware updated.

I'll post later with more solid test data, but so far the battery is indeed behaving much better.
