    Why is it important to charge new i760 for 12 hours?

    And does this have to be done before using it or can it be done at any time?

    Cause it came with a sheet saying..

    "IMPORTANT: Failure to initially charge your battery for a full 12 hours may lead to improper phone function or poor battery life."

    And it's weird, but I only charged it for like 3 hours, enough to get a full battery and the phone is acting weird. When I press the volume up, the sound that it makes is cut in half instead of the full beep. But when the phone is getting charged, it makes the full beep sound when pressing the volume. Weird.

    I'm thinking the 12 hour charge has something to do with it since it doesn't happen while it's being charged.

    It has to do with calibrating the computer's power sensor so it can accurately gauge battery life. I think you are supposed to to do a full charge, then a full deep discharge. When you do that, the thing learns so your power guage is accurate.

    Jay is correct. I will elaborate:

    Lithium-Ion batteries don't care, or have any less battery life if you partially charge them, even on the first charge.

    What matters is that the power sensor on the battery is calibrated so that your phone can acurately tell how much juice is left.

    If you mess it up, then just do what Jay suggests and let it drain all the way down (until the device will not run anymore) and then charge it fully. You can do this and should do this every now and then to maintain calibration.

    and this hurts because I always switch between the standard and extended life battery

    I full discharge of a lithium ion battery will reduce its useful life!

    I did a full drain, and full charge (9 hours), and have noticed no difference. The extended battery seems better than average (my battery sucked on my last phone by the time I retired it), however nothing impressive (first PDA, so it may be amazing), but nothing like I've read about on other sites.

    How are you charging? The wall/auto charger should only take 4-5 hours. If you are chargin with just USB then you may not be getting enough voltage to reach a full charge.

    Wall charge. Tried to charge as close to 12 hours as possible.
