I am at least going to give it a shot on an exchange (hopefully for a new unit). Part of what worries me is that the battery was completely flat out of the box, which makes me think a bum battery. The battery gauge is also the most innaccurate thing I have ever seen in my entire life.
There still seems to be some drain going on for me, even with reseting after a charge, but not as bad. It is hard to tell though.
Last night I checked at about 8:30pm, the battery reported as 93%, then 5 minutes later when I "double checked" it was to 96% again. I checked again at around 10:30pm and it read 95%. I went to sleep, woke up and checked it at about 6:30am and it read 91% for about 3 seconds and then flashed 71%. Crap. I checked it again right before leaving my house 5 minutes later and it read 70%. I got in to work a few minutes ago, checked it again and it read 70% for a second, and then back to 91%.
The temperature variation on the device can't be more than maybe 2-3F at any point in checking it (with the exception that checking it after getting in to work it might have been a little cooler without having fully warmed from having been in my brief case in a cold car for a 15 minute drive).
So to a degree I am willing to chalk it up to a horribly innaccurate battery meter to some degree, so long as there appears to be no significant drain continuing. I am going to try topping it off on my computer tonight both to go in to my 8 day vacation (starting tomorrow) with a full battery charge, and see if topping off on a computer combined with a reset/power off does anything (maybe even simply recalibrates the battery meter a little more?).
If I still seem to have bad drain (battery not lasting the length of the vacation) than I am going to try to exchange it the weekend I get home and hope they will do that (it was a gift and I don't have the gift recipte, I stupidly threw it out) and hope I have better luck with the next one.
If I just can't get the battery to work properly than, I also am going to be stuck going with a Kindle. I dislike that because I also generally like the hardware on the nook touch better, with the exception of these battery issues, and generally like the interface/OS/Software on the nook better as well (I'd change a few things, but mostly I like it).
Having 3GB of user accessible storage (without needing an SD card) and a working battery would be nice. I'll miss the physical page turn buttons, shelves, fast paging and slightly smaller size/weight though (I also HATE having a power button on the bottom of the device, I know darn well I'll end up powering it off plenty of times by accident reading on it). I NEED something that is going to last more than a week on a single charge though.
