I had real battery drain issues after I finally got a good nook that had a working charging system. I seemed to be only holding a 100% charge for 1 day before it got critically low ( nook on sleep).
I read on the nook devs site that if you rooted your nook and used trook than you need to manually go to the settings in trook and manually exit the app. Turning off WiFi does not do it. The battery will still think its on wifi.
The minute I manually turned off trook my battery problems stopped. Now I only lose 2-3 % when on sleep for 12 hrs. It use to be 50-75%. It is at 91% and It's been on sleep for 2 days. Used very little. So Hooray!!! Battery problem solved.
