2. Up to 7,500 continuous page turns with a single full charge on internal rechargeable battery. Actual battery life may vary upon usage patterns, product settings, battery, and environmental conditions.

1000 page turns is still 2 days, even if you read every minute of those days, better battery life than any other electronic.

btw, every time you make a note, you flash the screen again, so for every note you make add about 3, unless you are typing, then add 20 per note, and see how your figure turns out. every time you turn the device on, every time you open a menu, etc etc. thats all part of it.
