From time to time my DROID MAXX ends up dead with zero charge after overnight charging. This happens with Motorola's charger and Verizons charger. I have to plug it into my computer for a coupla hours before it's usable again. Verizon sent me to Motorola and Motorola promised to replace the phone but now they don't know who I am. I need a reliable phone. Any sugguestion..?
