[Q] N4 very, very slow QI charging
I bought a generic QI charger (there isn't so much choice in HK for QI chargers) to use with my N7 and N4.
My N7 (stock rooted) charges no problem, with a cover as well.
My N4 (CM 10.1.3) on the other hand just does not charge. The QI charger indicates that the phone is on the plate and the phone says it is charging via "wireless", however when I take the phone off the charging plate after say a few hours the battery indicator has only gone up 1-2% and sometimes not even changed. I have the N4 in a poetic bumper and I haven't taken off the plastic that came with the phone on the back. The phone charges fine when plugged into a wall charger.
I should also add the phone gets quite warm when I take it off the charger.
