Hi there,
Your explanation only points to several potential causes of the problem. Here are the common culprits:
1. Parasitic draw. It happens when an electrical component continues to draw power when the vehicle is turned off. (caused by faulty relays that do not switch off properly, aftermarket electronics, ECU, or other control modules that do not go to sleep mode).
2. Faulty alternator. A failing alternator will not charge the battery properly and could also cause battery drain.
3. Electrical short. Somewhere in the vehicle's wiring can cause unintended battery drain. It is sometimes difficult to identify but is often associated with damaged or exposed wiring.
4. Faulty sensors or actuators. Sensors and actuators can sometimes malfunction and draw power unnecessarily.
Still, it is best to refer to your trusted local auto repair shop and or mechanic for the appropriate troubleshooting methods and diagnostics to be done. I hope this helps!
