Dead battery/electrical functions problem

Hello! I have a W205 C220d 2016 and have been having problem with battery drainage overnight/after 12+ hours. The car won't start and sometimes I have to use the mechanical key just to open the car and then kickstart the battery. Sometimes I get a yellow warning light with the battery icon, and it says start the engine, check the instruction book. I have changed batteries two times, and checked the generator which seems to be working fine. I've had this problem for about two months... Dead battery/electrical functions problem
