A problem with battery - Barnes & Noble Nook Tablet

When I used NT unrooted, it's still battery level while unused 3-4 days, but when I root it with Indirect method and install some apps, the battery remain 60% after 2 days unused :|, I've tried some "kill process" app but it's seem didn't work . Any suggestion? Sorry because I'm newbie

Im afraid one or some apps waste your most of power
you should check it one by one yourself
once time, I got a theme of go launcher from market
but I found power droped 20%-30% per hour(just unused)
when I uninstalled it , it came back to normal

I've got a question about strange battery behavior.
This is my battery use graphic
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
There is no mistake, charge level raises when my NT's screen is switched off, is it a normal behavior for NT, or just an app glitch?
Can it be somehow connected with that after I plugged my NT into PC via generic microUSB cable charge level jumped from ~80% to 100% in a minute?

Most batteries will recover a portion of their apparent charge if given the opportunity to relax. {Electrons are able to move from deeper within the battery media and gather near the surface.} (There may be an algorithm issue as well, not sure.)

That is indeed strange!

Thanks for the answer, but it still seems strange, I am used to self-discharging batteries, not to the opposite. Also I didn't see something like this happening with Nook Color or mobile phones.

I did have the same with Nook Color, but I still have no idea why it happens and what the consequences are.

I would try to see which app is keeping the tablet "awake" when the screen is off.
(I know you don't have CM7 installed, but if you ever do...there is a utility in CM7 spare parts in battery history that lists apps by Partial awake usage that I check to see whats keeping it awake.)

FYI, Spare Parts can be downloaded from the market. It's not special to CM.
