Does anyone knows if you can charge the phone with the USB connection ? If you can, what setting do you change ?
Charging
If the phone supports USB charging, there is no settings to change; just plug it in with the USB cable.
If the phone does not support USB charging, there's nothing you can do about it (except getting an USB charging cable where the other end has a regular charger plug).
That is one of the great innovations of cellphones today. You can now actually charge your phone through your PC or laptop with USB connection. You don't really need to change any of your settings, if your phone supports USB connection then just plug it in and let it charge. One main disadvantage though is that is not as efficient as direct charging.
no, not USB charging on the X6.
