    Sorry to bring this up again, but I'd thought the problem was
    beat. It's happened again.

    The phone is my wife's Sanyo 4920. The battery is brand new.
    The phone has been put through diagnostics and techs claimed it passed
    the full complement of tests, including charging tests.

    Three times now the battery has run down to completely empty
    within a matter of hours of being fully charged. But these events were
    random, and between the events the phone behaved perfectly normally,
    retaining its charge as long or longer than my 4920 with a somewhat
    less new battery.

    I can't imagine what's going on here. Has anyone ever heard of
    this?

    Thanks in advance, DGI

    I had similar problems with a new Samsung phone. It turned out to be
    faulty. I learned this when took it to the Sprint store. They replaced
    it immediately. They didn't have a refurbished phone in that model so
    they gave me a new one. I was very pleased with the way they treated me.

    Has this phone been replaced at any point? Or was ti just the battery?

    There's two possibilities here. Either the phone is faulty, or there's
    a network related problem. If the phone is faulty, a replacement should
    do the trick.

    As for the network, what kind of signal are you getting? Does signal
    strength fluctuate during the day? If at any point you wind up in a
    fringe weak signal area, or you lose signal completely, any CDMA phone
    will burn through its battery as it searches for a signal to lock onto.
    And if roaming, the phone will still use slightly more energy as it
    periodically checks for a home signal (and will expend a LOT of energy
    if it's roaming in AMPS mode).

    I've had positive experiences with immediate replacement as
    well, but that was under warranty and I don't carry the insurance.

    However, I did have the phone tested and nothing faulty was
    found.

    This phone actually IS a refurb. I bought two when they came
    out in June '04, and my wife's failed one diagnostic test some three
    months later (when having a firmware update). She's been using this
    refurb. since with no problems at all. This happened with the old
    battery, and I thought that was the problem, so I got a new one.

    Just had diagnostics done at the local store and was told that
    it passed all tests. I suppose I could run it through the testing
    again, but if the techs found no fault I'm not sure what good that'd
    do. The phone is no longer under warranty.

    Now bear in mind that we both use the same phone under exactly
    the same conditions, so network problems should not affect only one
    adversely (I don't think).

    No, that's all consistent and trackable. For a while I thought
    that my wife might have been keeping hers somewhere (such as next to a
    large power source) that was zapping signal away from it. But when
    this recently happened again, she was definitely not. Phones are set
    to "Sprint pcs only"

    All signs point to a fault in the phone's hardware, it's just
    that they didn't see one. That's the frustration. Thanks for your
    advice.

    Unfortunately for the problem you're having, I doubt their diagnostics
    would have uncovered the fault. The Handset Performance tests that are
    done at the store are geared towards measuring RF performance and phone
    functionality. It's highly doubtful they did any meaningful test to
    determine power consumption or battery capacity.

    Roaming analog ... put the phone in "Sprint PCS Only" mode.

    Both phones have always been in "SPCS Only" mode.

    Thanks anyway. DGI
