    How essential is a full charge before usage ?

    Hi guys ,

    I wonder if there is any problem to recharge the battery till a specific level which is not 100% but , for example , only 70% .
    I'm asking it because very often I don't have the time to wait for a full recharge .
    So , is this issue really essential ? Can it damage in any way my battery life time ?

    Tnx ,
    DJ

    Don't worry about it. The batteries used in tablets these days are regulated by their own chip. They stop charging themselves automatically, and when full, they drain themselves to about 90-95% before charging again.
    Charging it multiple times (either to full charge in one go or by charging it for just 15 minutes 20 times) doesnt make any difference as well.
    Just keep it away from extreme temperatures (both hot and cold) and it will be fine.

    Letting it drain to 0 percent is never good for a battery, but will only give you trouble if it is left like that for a long time.
    That said, the dock will drain itself to 0% when it recharges the tablet. But dont worry about that, there is a safety reserve built in. It will indicate 0 when there is still plenty juice left to keep it healthy.

    The 201's owner's manual is probably similar to the TF101 in recommending you go through several full charge-discharge cycles with a new Transformer. By discharge plug it in around 7% and it shoud be fully charged in about 2-1/2 hours.

    Everything I've read that discusses li-on batteries scientifically says there is no need to do any kind of full charge, cycling, etc.

    Having said that - the way devices measure battery life is not exact, and I think it's possible that the microprocesser in the device battery needs a few full cycles to 'learn' the battery's capacity and that's why it's recommended to do a full charge the first few times.

    I do it just to be safe.

    When the dock is at 0..can't use the keypad .. I normally take the tablet off and charge the dock separately ...

    That shouldn't happen. Mine works fine when the dock is at 0%
    Would be weird if it stopped working if you still have some 8-10 hours of battery left on the tablet itself...

    I agree something is wrong with your dock if it stops working when the dock battery is depleted. you might want to have that checked out.

    Also everyone is 100% correct about Li-ion batteries not having memories and not needing to do the whole run it down all the way drill. The only thing I would add is that if you ever plan on storing the tablet for a long period, I can't imagine going without a tablet at this point, you should get the battery in the 35-45% range. That is what has been recommended in all the reading and research I have done.
