2014 Buick Verano battery died, auxiliary wiring

What is your question?

Car was perfectly fine went into Walmart came out 20 mins later car won't start flashes roll down and back up driver window, didn't have enough juice. Service Stabilitrak, power save mode, interior lights would flicker that's when I realized that I could turn on my radio without the key in so I figured I've got a wiring problem. Was gonna let it sit for a while and go see if it died again... when I jumped it it started right up had me roll my drivers window down and back up put the dic screen back to normal and I took off home no problems the whole drive... non turbo
