Help LG Phoenix 2 QI Charging Issues

[prackley1]

I have an LG Phoenix 2 and recently purchased a couple of QI receiver pads (5 volt 1000mA) and an LG WCP 300 charging base, and was successfully able to wireless charge my phone for maybe a day, but now even though the charging base blinks green to indicate it is charging, it no longer does. Even tried swapping out the QI receivers and a different generic charging base. No luck. However my child has a Samsung Galaxy Express 3 and it works fine. I've tried with and without a case but still no luck. Is there perhaps a phone setting I need to check/change? I'm stumped...
