yoon27 there’s communication between the phone and charger every 15 seconds or so, so it could be a hardware issue of a software issue.
I’ve done a bunch of experiments with my NP3 and CMF1 and on the CMF1 the charging got my finicky after the NOS3beta update, which I only require 1-2 additional plug-ins to generate correct communication and 25W+ charging with my 30W PPS charger.
I can’t get over 40W on the NP3, which is noted online everywhere, but that’s enough for me.
