Plugged mine in, using Samsung charger and Samsung usb cable. Popped my phone on (which already had 57% charge), and was advised, by my phone (Galaxy s7 Edge) that it would be 2hrs 54mins before fully charged (that's from 57%!!
Plugged the cable into my phone, and to achieve full charge with usb cable (as opposed to wireless) would be 56mins (a difference of 1hr 58mins!
Does anyone else find this?
Equates to 6% per HOUR or 2% in 20 mins!! (NOT impressed) :-(    -
