Well, I'm looking specifically for the usb 3.0 cables, the guy at the AT&T store called them "fast charge cables". I have been using micro B usb 2.0 cables but I have to turn off my phone entirely to get it to charge that way, otherwise it just charges at about 1% every 5 minutes, that's with all the apps closed and the phone locked....just realized I usually leave my wifi on... but still, I need the 3.0 cable that looks ~twice as long as a usb 2 micro, and I can't find it anywhere
