    1) Disabled the vibration upon pressing the screen.
    2) Disabled the constant syncing of my email, twitter (I just press the "sync" button if I want to see if I got an email)
    3) For those who read ebooks - in a room full of light, switch to "night view" - background is black - less battery.
    4) I canceled the flipping of the screen (horizontal/vertical) especially because I mostly use it vertically.
    5) I tend to cancel WiFi unless I'm not 1-5meters away form the spot. If the signal is too low the battery will be drained very fast.
    6) Updated to TouchWiz

    I'm not sure about killing apps when idle - if there is anyone who can elaborate on that (does it actually help the battery/or not) I would appreciate that.

    Doing the above I was able to get 3-4 days with sporadic usage on the tab.

    How do you switch to NIGHT view?

    With non AMOLED screens the tone of the pixels is a wash. It uses the same amount of energy for dark pixels as lighter ones.
    The opposite is true with the AMOLED of the Samsung Galaxy phones and HTC Incredible first generation. A less complex theme can have a negligible effect on power consumption but with the back light being such an energy drainer, that is the best place to focus for savings.

    For battery preservation, is it better to run the SGT until the battery charge is quite low before recharging, or may it be recharged at any time with no problem?

    The batteries in most modern devices prefer to not be run down totally.
    You should get at least 500 charge cycles (plug in and charge) before noticing any significant difference in battery life.

    Some technical information about how our battery works and charging it.
    http://batteryuniversity.com/learn/a..._ion_batteries
    There are a few more threads I've found in other forums that further explain why letting it drain every time fully before charging can be harmful in the long run.
    PM me if anyone wants the links

    Thank you for the prompt reply and the link in your next post. A further question, does recharging cease automatically when the 100% level is reached? Charging overnight is the most practical, but that likely means the Tab will remain plugged in for some time after recharge is complete.

    With modern chargers they stop charging when full. You don't have to unplug when full.
    Basically what happens is once the Tab is full it stops charging but if it is on it also will begin to drain again. Once it gets below a certain threshold (usually around 80% but the Tab may be different) it will start to charge again. The confusing part can be you plugged it in overnight and it says it's full but as soon as you unplug it, it drops as much as 10% right away or shortly after. This is normal when charging while the Tab is on because the sync between the battery meter and actual battery are not accurate while plugged in and on but the sync between the battery and charger is accurate. Once you unplug you'll see an accurate reading, the sudden drop, because though it was plugged in it was using battery and not enough to kick the charge cycle back on.
    If you want maximum battery life either charge while it's off (recommended method) or when you get up in the morning turn the Tab off and let it charge again, also called a bump charge because it "bumps up" the amount used after it filled and stopped charging (puts more stress on the battery but will add run time and still allows the Tab to be left on for the main overnight charge)
    Hope that makes sense

    It makes perfect sense! I always recharge with the Tab off and will continue to do so. Thanks again!

    My batt only last for 12 hours eventhough i let it until 1% then off to recharge to 100%.
    But after using Andoid Task Manager, it can run my tab for 22 hours!
    I always online (never off except for charging)
    (^_^)v
