    are any of you experiencing this?

    I plug in tabby. go to bed. wake up to pee. see tabby is 100% battery. unplug and go back to bed. wake up to go to work and tabby is powered off completely and battery is anywhere between 85%-90% in a matter of 2-3 hours after being unplugged.

    What gives?

    Go to Settings / About Tablet / Battery Use - it will tell you what has been using your battery since last recharge.

    I'm guessing it's probably wifi. If so you can go to Settings / Wireless & Networks / Wifi Settings / Wifi diconnect policy and select When sscreen turns off.
    You could just leave it plugged into the charger while you're sleeping, even when it's 100%.

    I re-flashed with Taboonay v.2.0/Richardtrips v.3.3 Kernel and it fixed everything. Best ROM kernel combo ever! Super smooth, zero lag and amazing battery life!

    I think OP is saying that the power is off, yet battery is draining, so wifi or anything else wouldn't be the problem.

    I think I just experienced this. I had it powered off for a couple of days, and I'm pretty sure it was close to 100%, but when I powered it on, it was below 50%

    Yeah, I missed the bit about being completely powered off in the original post.
    This is a different problem, caused by non stock ROMs misreporting the battery level as 100% rather than battery drain.

    A fix for this problem is described here
    How To Fix Battery Drain Issue On A Rooted Android Device

    But it sounds like JiggaGeazY's solution is also super effective.

    Actually there is another theory i'm backing over at xda........the tablet is crashing in sleep mode and the tablet thinks it's on and drainning power because while long pressing the tablet to turn on i would actually have to long press the power button twice. Once was turning the tablet off and the second was turning it on. Plus the power drain i was getting was dead on with his theory and so was the sequence of power button presses. either way i fixed it and i'm happy! LOL thanks for the opinions and help though.

    One quick addition.... I don't know about when the display is off, but I *KNOW*
    that when it's on, if you aren't using GPS, but have it enabled, it is a serious battery
    hog.....
