I know it's not the cable that came with the charger that I got for free from BB cause I plugged in directly to the phone and it's charging nicely now, but I went to bed last night at 2:30 and left the N5 on the Samsung charging pad (got the animation when I placed it) with the battery being 19% and I woke this morning at 8:00 to a 24% battery. So the questions that I have are is this normal? I looked at the charger box and it doesn't say it's the fast wireless charging pad but even so, isn't that a bit weak for wireless charging? Could there be an issue with the pad I have?
