    Q: Why is charging of Motorola phones so slow on the travel charger?

    A: The standard travel charger packaged by Motorola with many current
    phones puts out insufficient power for fastest possible charging and for
    continuous use while charging.
    ----------------------------------------------------------------------------
    For example, charger SSW-0509 for the V551 puts out only 375 mA. The
    V551 detects this as a slow charger, and thus keeps the external display
    backlight off during charging. Worse, there's not enough current to
    keep up with use of the phone while charging, so while the phone is use,
    the battery will still be discharged even with the phone on the charger.
    With a fast charger the external display backlight is on during
    charging, and the phone can be used while the battery is charging.

    Motorola makes fast 1500 mA chargers that are compatible with these phones:
    * SPN4716* (where * might be "B" or "C"), also known as
    * NNTN4250 (nominally for Nextel, but also works with non-Nextel phones).
    These chargers are readily available from dealers and on eBay for under
    $15 (plus shipping).
    ----------------------------------------------------------------------------
    Motorola mini USB (EMU) chargers for RAZR, KRZR (with power output if known):
    * Wall "travel" (AC) charger (comes with the phone)
    + Motorola SPN5185/SPN5185A/SPN5185B/98604H: 550 mA (mid)
    + Motorola SPN5202/98605: 850 mA (fast)
    * Car (12V) charger
    + Motorola SYN1630/SYN0847/98603H/VC700
    * External rechargeable battery/charger
    + Motorola SPN5353/P790/98782H
    * (5 pin) mini USB cable to computer: 500 mA
    + Motorola SKN6371C
    ----------------------------------------------------------------------------
    (For what it's worth, Motorola probably saves less than $1 in cost by
    packaging slower chargers instead of fast chargers with its phones.)

    Q: Where can I get USB modem drivers for Motorola cell phones?

    A: <http://developer.motorola.com/docstools/USB_Drivers/Handset_USB_Driver/>
    [registration required, but free]

    1. UNinstall any existing driver in Device Manager before installing this
    driver.

    2. Install this driver _before_ connecting cell phone.

    Sort of makes you think that maybe, just maybe, Motorola does know

    OEM chargers or non-OEM chargers?

    With a properly designed charger (fast charge then topping charge) the
    difference should be fairly small.

    Higher current chargers don't "force" higher voltage, and full charge
    detection of Li-Ion isn't done by simple voltage sensing. (Charge
    cutoff is typically done from a combination of voltage and charging
    current.)

    Motorola sells both fast and slow chargers, as noted in my original
    post.

    Motorola fast chargers give just as complete a charge as Motorola slow
    chargers.

    The usual cause of premature charge cutoff is a charger that isn't
    designed properly; e.g., one that goes to "ready" at only about 70% of
    full charge by skipping the topping charge.

    And what makes you think he pays any attention to your replies? I've
    been lurking here a couple months, and I haven't seen him respond to the
    insults even once. He probably has his critics kill-filed.

    Posting responses like "yawn" and "same old drivel" does nothing to
    counter his FAQ or inform newcomers; it just reduces the group's s/n
    ratio and makes you look like trolls.

    If you disagree with his FAQ, why don't you drop all the name-calling
    and just post your own FAQ? Call it "The alt.cellular.motorola FAQ" or
    whatever you like, and post it as often as he does. If you believe he's
    wrong about Motorola's travel chargers taking longer to charge a cell
    phone, give your own version of the question & answer. While you're at
    it, include some of the other questions that have been asked in this
    group, and do your best to give useful & accurate answers.
