Check for parasitic battery drain. i.e. Do you have phone chargers plugged in, DVD players, LED Lights, Coffee Makers.Most systems keep these accessories draining even when the car is off. That combined with the internal Radio, On-Star, and billion other things going on behind the scenes your battery can take quite a beating. It's tedious and may be better to take it in for service to track that down.I had an old truck that killed the battery every 12 hours because a power mirror switch was shorted.

Fan crutch
