Please do another round of testing and find me a USB charger. I have a LG G3 and its very picky about what Qi charger and USB charger it likes. When working above 1 amp most the wall chargers draw down below 4.5 volts and my phone disconnects from the Qi. I didn't even think of checking for noise and ripple and how that would affect the Qi.
