Something wrong with my nook battery?
I purchased a nook second hand here last week. I charged it fully on Saturday night, taking it off the charger Sunday morning. I played around with it for maybe 30 minutes after that, but left it in standby after that until last night. I have only side-loaded 2 books. I turned airplane mode on right away. I picked it up last night to mess with it at Barnes and Noble, and I was already at 80% battery. Read for about an hour there, messed around with the in-store Wi-Fi for a few minutes, and it's down to 76%. This seems awfully low for basically 1 hour of usage. BTW, I have the touchscreen timeout very low so I don't think that's causing anything. It seems like the standby is what killed it. 20% from a few days in standby seems absurd. Any thoughts?
