Seeing that the battery uses only 2 leads to connect to the device, I suspect the device is doing an average measuring(since it does not have a hardware controller on the battery).
this makes me believe that numbers make only little sense. Meaning, when yo powerup the device,you'll see maybe 96% of batterylife? even if there's in reality only 20%left.
Then it would drop rapidly untill it'll stay somewhat around 19%.
Next time you'll restart the device same thing...
I don't think any measurement smaller than 20% makes sence here, since it would be inaccurate anyway.

The closest you can get results in % is getting it in 20% increments. Otherwise there needs to be a program created that keeps count of how many hours the device is active, and how many page turns.
Also if it's text or pictures, lrf or pdf, SD card or internal memory (since obviously the one consumes more energy than the other).
Such a program will consume battery,and would only be a softwarematic patch,though the device does not support it hardwarematic.

But then again Sony already uses a program like that which on average measures voltage.

Anyone has tried to let their 505 go completely empty?
