Slow USB Charging on Samsung SIII LTESupport

    My new Samsung S3 LTE phone seems only to be able to charge at 96mA through my Win7 PC. Kies/PcConnector all installed.
    Cable I'm using is a generic USB to micro-USB cable. As shown below, the Samsung phone charges at 96mA. The same cable connected to the same USB port (a powered USB hub) is able to charge my Blackberry at 500mA.
    Battery=18%.
    Note: View the elec current by finding the relevant USB hub in the Device Manager and viewing Properties.

    I don't have my original Samsung charging cable so not able to test whether that could be the cause... could it? The Blackberry experiment seems to rule that out.

    Thanks!

    Its likely the cable. I also experience slow charging on my Galaxy S if I'm using a generic cable.

    Thanks. Can I ask what characteristic of the USB cable is different? (USB 3.0 vs 2.0, for example?) Otherwise I might go to the computer store and see if they know. Will be easier and cheaper to buy the RIGHT generic if there is such a thing.

    I, too, have the same challenge with charging. I use the OEM which came with S3. Sometimes it takes six hours to go from 50% to 90%. Maybe it is the meter? But I do know it charges down quickly too....

    Apparently this is normal. I spoke with someone about this topic as well. They said that because the USB is the second priority charger, it's slower (apparently).

    Phone manfacturers branded chargers are mostly coded (with their USB port) to force their phones for rapid charging with more current than on USB ports of PCs.

    If they have the same coding (mostly jumped data pins) ... a BB charger will rapidly charge a Samsung phone :)

    Connect your Galaxy to a HTC charger and you'll have the same rapid charging.
