    Anyone know the proper way to get a new battery off to a good start? I have
    a new Samsung x427 coming with a standard battery. I've heard that you can
    impact the length of time a battery will hold a charge by how you charge it
    the first time. I you know how this works, please share it. Thanks in
    advance.

    If its a Lithium Ion battery, it doesn't matter much. Older Nickel
    batteries work best letting them become almost totally discharged and
    then fully charging them.

    Yes, whatever you do, do NOT follow the instructions in the owner's manual.
    One very knowledgeable tech. I spoke with theorized that the instructions in
    the owner's manuals were specifically designed to KILL batteries so that the
    various phone manufacturers could sell more batteries. I know it's that way
    with my wife's Mot T720. The instructions in THAT manual make no sense at
    all.

    Here's the proper procedure . . . (it'll be tough as you want to play with
    your new toy, but you've gotta do it)

    1) Charge phone without using it for a full 24 hours. It might show full
    after a few hours or even 30 minutes, but you MUST charge it the full 24
    hours.
    2) Use the phone and DO NOT TURN IT OFF until the low battery warning
    and/or the phone shuts itself off when the battery dies
    3) Repeat steps one and two TWICE
    4) Now use it however you want and charge it whenever necessary or whenever
    you want to, whichever comes first

    We conditioned our two Cingular phones (nokia 3595, mot t720) this way. We
    are one of the few users of the t720 that don't complain about battery life.
    At moderate usage levels (my wife carries it and you know how women gab),
    the t720 will go four to five days between charges without ever being turned
    off. My 3595 (which I don't use as much as my wife would) has gone four
    days without being shut off and still showed FULL on the battery meter.
    (wow!) I haven't tried it, but I'm betting I could go two weeks between
    charges with the nokia 3595. If I carried the T720, a full charge would
    probably last more than a week the way I use it. -Dave

    NOPE. Those instructions are left over from Nickel-Cadmium batteries,
    which hardly anyone uses anymore.

    Re: Initial Battery Charge

    the very first charge should be for 24 hours and then after that wait till the
    battery gets really low to recharge.

    hmmmmm, I always put my phone on the charger when I go to bed and take it off
    when I get up. Really works just fine and I haven't had to replace a battery
    since my last AMPS only Portable.

    My CDMA Sprint phone sometimes goes into AMPS roam and for that I do have an
    extra battery and the desktop charger witll charge both of them at the same
    time for me!

    But for all the other phones, I haven't run out of battery during a normal day.
    Sometimes even for two days.

    Here is a posting from a battery engineer that I saved some months ago
    which explains the issue. I've seen postings indicating that, if the
    battery has sat on the shelf before you buy it, the reocmmendations below
    might not apply and it'd be better to do 2 or 3 full charge cycles to re-form
    the insulating layer:

    Actually conditioning (formation of semi-insulating layer on the anode particles)
    is done by battery manufacturers. They are required to make the formation cycle
    before they ship the cells. Formation is not completely finished in one charge cycle,
    so in case of some manufacturers who make only one formation cycle,
    cells will still show increased capacity loss during
    a comple of additional cycles.

    Also, most of new high capacity cells have increased useable
    capacity loss during first 10-20 cycles, and then capacity stabilizes.
    This has similar reason - still growing insulating layer increases cell impedance which
    in turn results in less useable capacity at high (say C/2) loads wich are common
    in notebooks, phones and PDAs.

    There is no need to deeply discharge the battery for make formation cycle.
    Insulating layer will be formed in the natural cause of battery usage (mostly
    during charging stage).
