I've been dealing with slow charging forever. I eventually replaced the USB port itself (not for the impatient), but my OEM charger started to come apart near the USB side so I replaced it with another OEM since that's the only charger that seems to work at all. I ended up with slow charging, but it does work. Here's the OEM charger on Amazon. Sorry for the long link.
