I made the same experiences with my brand new 505.
Converted and read 2 books with pdflrf to Image LRFs and got something around 400-500 page turns in 9 days until the battery ran empty.
Didn't shut down the device but put it into standby mode using the power switch.
The 505 was charged using USB.
I found a 5V / 500mA (maybe it's able to serve more amps) Power Supply which I used to charge this time. Full charging took about 1,5 hours while I was reading.
Next time I'll use a professional power supply to see what current is actually taken while charging the 505.

Does anybody know, which capacity the internal LiIon battery is rated?
