Having said that, the supplied charger and cable is particularly good. My phone charges much more quickly with it than any of the numerous alternatives I have tried.
That's interesting that there's a difference in the speed of recharging the phone with the OEM cable/plug than aftermarket ones. How long does it take to fully charge the phone (from 0% to 100%) with the Samsung white cable/plug? I'm curious to compare that time to the 3 hours it took w/ my Motorola D3 cable/plug I used this morning.
