    Hi,

    I've done a search - apologies if this is a repeat thread, but does anybody encounter any issues when charging their phone via USB? If the battery is <10% is can take up to 8 hours for the phone to fully charge with minimum use whilst it's charging via usb as compared to 90 minutes or there abouts when plugged into the mains.

    This doesn't seem right; the voltage should be the same so why does it take so much longer when charging via USB? I get the same charging results if it's plugged into a desktop, laptop or PS3 so that rules out a defective USB slot.

    Is there anyway I can optomise the charging time when charging via USB? This issue might seem quite trivial but it would make life a bit easier if the charging time was the same by charging via USB as it is via the mains.

    via usb it is 'trickle charge' via plug it is full whack, no way around it it, as USB and PC's have limitations in power output through the bus.

    USB, 400ma MAX if you want a faster charge use the mains adapter.
