    Hello,

    I'm just wondering if anyone knows if charging via USB or an AC adapter give a better battery life on the iPod Touch?

    Obviously, there is going to be a lower voltage on the USB port but does the computer accommodate this by charging it for longer than it would do on the mains?

    So which is better...charging on the mains or usb?

    Thanks

    Well I disagree.

    If you charge by USB it takes longer, thus using more battery.

    Wall Charger takes less...

    Wait Nevermind...

    I'm not quite finished with me theory here.

    Since it is the same voltage, shouldnt the charge take the same amount of time?

    its not the same voltage going through though because some of the voltage is being used to run the computer

    Well it's 5v and 1A with the official apple charger. Anyone know about USB 2.0 ports...or do they not have the same voltage?

    Usb ports are a maximum of 250mA I think @ 5V

    Ok thanks.

    That would explain the long charging time on the USB compared to the AC Adaptor.
