    This morning on my way in, I used it in high power mode for an hour (I drive kids, a couple of which I pick up along the way, to 2 schools and then come in to work) and it used 20% of the battery, almost entirely attributed to the screen (according to the battery monitor in settings). I am going to try low power settings on the way home. CoPilot has a setting for fewer screen updates and I will also select the option to only turn on the backlight near turns.

    I use Navfree USA: Free Satnav, I never mess with brightness on either OS, they use default brightness, 3 to 3 1/2 hours JB is about dead ICS same time frame is around 50%.

    I tried a free one first; I can't remember whether it was that one or not. Unfortunately the free maps for my area are in sad shape; counties wrong for some cities but right for the roads and it made it virtually impossible to enter addresses. Better maps from TomTom are $20 but CoPilot was only $9.99 with good maps (and there is a free one that lets you test pretty thoroughly first) and I like the UI a lot better anyway.

    I wonder how well % correlates with reality. If one hour takes the battery from 100% to 80%, that doesn't mean I would get 5 hours. Besides the tablet cutting off at 6% or so, I wonder if the exact same drain that took it from 100-80 would take from 80-60 and 40-20. Based on past experience with other devices, I am betting not. I suspect that full power mode in CoPilot probably make it less than 4 hours. But because most of the power seemed to be for the screen, I have high hopes for the power saving mode...

    I can get it under 15% per hour using lower power saving settings. It is route dependent though, because I am choosing the option to only back light (turn brightness full) near turns. I could get it lower by choosing device settings and turning brightness way down. Most of the time that would be fine since the audio directions are quite good. But I think having it bright near turns is more realistic.

    How long of a movie? That 10% number sounds really low. Usually it is between 2 and 3 movies to drain a battery on most tablets. I watched movies and played games on ICS before upgrading and there is no dramatic difference in battery life since going to JB.

    BTW, Airplane mode has wifi off, but supposedly drains less than wifi off. I leave wifi on all the time, connected or not.

    Pretty good for me.
    If I am Surfing, Emails, Watch Videos, Listen to some Music while working on it, Downloading some, and Play games I got around 9 hours before hitting 10%.
    Now solid gaming approx 6 hours.
    And mine is set on Auto Brightness with Wifi on all the time.
    Not bad at all in my opinion.
    My Iconia A500 had a Tegra 2 in it and it didn't get any better then that.

    If I was just listening to music and surfing and maybe doing some work on it.
    I figure I'd get around anywhere between 9 to 12 hours easy.

    As I said not bad for a $200 tablet and a $500 Asus is only rated at 10 to 12 hours.
