    Phone always charge when connected to PC via USN since upgraded to WM6. Is there a way to disable charging each time synching to PC?

    Not that I know of - many people were delighted by this change. Why aren't you?

    No kidding. Why would you want to disable USB charging?

    Only reason I could think of is if you were trying to discharge your battery intentionally, but why would you do that? Lithium Ion batteries are not susceptible to memory like the old Nickel Cadmium rechargables, so they don't need to be fully discharged before recharging.

    You're better off topping it off whenever you get a chance, especially given that it's only a 1200mah capacity.

    The only reason I could see that you needed to completely discharge the battery would be to calibrate the battery meter on the device, ala my Treo 650 days. I never did it on my 750, and haven't seen the need to.

    Reason is that I sync to PC very often each day. Work better off PC and do not want to have Treo charge each time I sync (each sync's very short, 1-2 minutes). Bad for battery if recharge too many times.

    Actually, it's not.

    Old tech rechargables like the Ni-Cad are prone to developing a memory and should be fully discharged then fully recharged to prevent this.

    The Lithium-Ion batteries in the Treo (and most new devices) do NOT have a memory effect and can be charged for as little or as long as you like at any point with no negative effects.

    Still don't believe me? Page 11 in my manual has this to say as the very first suggestion in the section titled "Maximizing Battery Life":

    Battery life depends on how you use your Treo 750. You can maximize the life you your battery by following a few easy guidlines:

    * Charge your Treo 750 whenever you're at your desk, or charge it overnight every night. The battery in your Treo 750 has a much longer useful life if you charge it frequently instead of waiting until it's fully drained.



    Just goes to show that not all rechargables are created equal. The newer batteries require a different way of thinking. In this case, more frequent charging is actually GOOD for your battery.

    If you were connected to a laptop running on battery, perhaps you wouldn't want to be charging off of it?

    Laptop USB ports are not usually powered anyway.

    Huh? All USB ports are powered.

    USB connections are not serial ports, they are connections on a serial BUS. The hub controls power management for devices that are bus powered. On most PC's the "hub" is either an add on card or built onto the motherboard, but in all cases the bus is provided power to function.

    Now, you may run into cases where the hub in incapable of providing enough juice for a bus-powered device. This can happen with power hungry devices, or with unpowered external hubs (where the power must be shared). When this happens, you're PC will normally tell you it can't provide enough power on the bus.

    So while your laptop's internal hub may not provide enough power to run what you're plugging in, it is most certainly still providing bus power. Otherwise, all my power cords with USB terminators would be useless.
