Hi all, I'm new to the Android world (and new to smartphones in general). Trying to catch up on about 7 years worth of mobile tech, so please bear with me. I'm very happy with my LG Optimus G, but when I charge it via wall outlet, I keep getting a message that says "Battery is charging slowly due to low electric current of TA/USB connection." I don't understand what this means. It does seem to charge way slow, though. I'm using the factory charger that came with the phone (Sprint model). I can charge it in the car with a car charger and indeed it does charge more rapidly and I don't get that message. This is not only annoying, but I assume that since I'm getting that message about it every time I plug it in, something is not right. Thoughts/help?
