I have an LG Optimus V with Virgin Mobile. I plugged it in to charge while I went to sleep like always. I won't up around 7 a.m. to the sound of my phone restarting. Looked at my phone and the battery was almost completely dead. And yet, the little icon indicating it was hooked up to the charger (had the little lightening bolt) but the little animation of the battery filling up wasn't happening. My phone won't charge. I tried taking out my battery and restarting but it didn't work. What should I do?
