Pet Peeve, battery charging

We recently purchase a 2023 Model 3, standard range. I notice the battery goes down even if it's parked, maybe one or two percent, especially in hot weather. Last week I drove the car to L.A, where it's been 100 degrees or more in the valley and I had to charge it numerous times. at one point, during my stay, I charged the car and the battery dropped by 7 percent over night! Then when I drove back home to NorCal, I haven't had to charge the car nearly as much as when I was in L.A. Is that a common thing for most Tesla owners ? I just wanted to get everyone's opinion as I find this experience kind of comical.
