I suggest you try to track down precisely what's causing the excessive battery drain. You can do this by keeping track of your battery SoC at various times, beginning with before and after each drive. If you drive ten miles and the rated range goes down 100 miles, then the excessive drain comes from driving, or at least something happening when you're driving (like the heat running full blast), so you should focus your troubleshooting on those issues. The Tesla's energy-use graph may help you figure out where excessive driving use is occurring, too. If the rated range goes down 100 miles in ten hours while the car is parked, then the range loss is vampire drain, and you can look into the vampire drain issues I noted in my first post. (Of course, the problem could be a mixture of these two things.)
You might also be able to glean some information from a Tesla data-tracking tool like TeslaFi or various third-party Tesla apps. At a minimum, these will help you collect the data described above. They can also help by providing more detailed data, such as identifying the power consumed by cabin pre-conditioning. OTOH, there are security implications to using these services (your data, often including your Tesla password, end up in the hands of a third party); the data may seem more reliable than they are; and such tools can sometimes keep the car awake unnecessarily, which can increase vampire drain. Still, it's worth considering using such a tool, at least for a week or two to help you debug the problem. (TeslaFi is a paid service with a two-week free trial, but you can boost the free trial to a month with a referral code in this YouTube video. Note that I'm unaffiliated with that video, except having viewed it.)
