I take a usb extender cable with me to the university.
it looks like this one:
unfortunately, it charges really slow when I use it.
anyone knows the reason?
there are some guides on turning a usb cable to "charge only" cable.
it just doesn't make sense that a cable that IS capable of transferring data (like the stock N4 cable) performs normally, while this one needs to have the data pins shorted to charge normally.
I am running OmniROM with Hellscore kernel and use fast charge without a difference in charging speed.
