I bought my LG G3 mid Sept. 2015. I am beginning to have troubles with it. Today is the third time it won't charge, or is super slow to charge. I have been using the adaptor and cord that came with it. I have tried restarting and also removing the battery, but it still won't budge. I don't leave it plugged in overnight (often) (My son gave me crap for doing that, so I don't unless I need to). I am a bit anxious since I will be travelling in the next couple of weeks and kinda need my phone to behave. Any suggestions?
