    Sounds more like a bad battery. Warranty? Take it back.

    Are you closing all applications when you're finished with them? Menu key, scroll down to Close. Also look here:

    I had a similar problem with my 8800 and the tech had me reload the OS deleting the original. It worked for that.

    No. The proper way to close an application (and thereby save some battery power) is by pressing the menu button and clicking Close.

    Put the device through 3 complete charge/discharge cycles. This involves running the device until it shuts off on its own due to low battery.

    This is not necessary. That's for the old NiCd batteries! BBs use LiIon batteries.

    Read the links below.

    Thank you for the info; I'm very well versed in the charging methods/care of the different types of batteries. This is not to reduce the "Memory Effect" but rather to get the battery's true capacity to sync up with the device.

    Even the literature on charging li-ion cells indicates that a complete discharge once in a while is a good idea.
