I purchased the Kindle 3 Wi-Fi last Thursday.

Initially, I did not read the instructions and only charged it until the yellow light went out on the device and the green light came on.

I started reading soon after and in about a day the battery was at 25% (the battery indicator showed 25%).

So, yesterday I left it charging for about 4 hours, the battery indicator was full at the time.

I then read for an hour at night and left it. I usually "leave it" and I believe it goes into sleep mode after some time. The wireless is always switched off.

This morning I checked and the battery was at 80%.

Is there any reason why the battery is dropping so quickly? Should I be doing something different?

Thanks!
