Bring Windex and some rags. When you return, your car will be dusty LOL

battery drain airport parking

It seems to me the newer models are more efficient. I just came back from vacation for 3 weeks, I left the car at home garage not plugged in. Sentry and cabin heat protection are off, wifi connected, have scheduled charging on. I never checked the app but I did got a software update install notification in the middle but ignored. At the end I lost around 1% per day for my 17MS75.

This is really not applicable to airport parking as it depends on how long you will be away and how far you need to go when you get home. The 50% recommendation is for people who store their cars long term.

Agree that 50% is best for long-term storage. For a couple weeks, 70% is OK. Not so good to leave it at 100%

So long as the energy lost while parked, and what is needed to get home are considered, I suppose 30% is just fine.
However, unless someone is going to keep their car beyond the 7-year battery warranty period, worrying about battery degradation is, IMHO, as waste of brain cells.
I agree, the obsession with minimizing battery degradation is not necessary. Moderate loss of battery degradation doesn't affect daily driving whatsoever. Even a 10% range loss doesn't make a difference in any but the most extreme situations.So long as the energy lost while parked, and what is needed to get home are considered, I suppose 30% is just fine.

What I did find pretty annoying with my old Model S was the reduced charge speed and forced thermal management as the car got older. It wasts a lot of energy and made road trips noticeably longer. That's something no one thought about in the beginning. But now it's an issue with all early Tesla vehicles. We don't know what issue will come up in the future. I try to learn about batteries and best practices to extend their lifespan. I'm not letting it dictate how I use of my car, but when I can I follow them because it's easy to do without compromise.

Yeah nothing bad happens. I even depleted mine past zero percent and did a battery health and nothing changed.
If you're gone for over a month with ZERO charging options while away I wouldn't mind charging to 100 and leaving it parked.
With everything off though it's literally maybe 1% a day, maybe less.

I'm on my second 3 week business trip out of country. Last time, all I had to do was turn off Sentry mode and cabin overheat protection. The car lasts a very long time in sleep mode. On my first 3 week trip, I lost maybe 3-4% battery percent. I supercharged right before I parked it because I wasn't sure how long it would last. I charged to 80%, drove a few miles and parked it at about 76%. When I left my spot it was at about 71%. However, it was still slighty winter time and I preheated the cabin as soon as I picked up my luggage and was waiting for the shuttle bus. So that's why I say about 3-4%.
I'm on my second trip now and will be returned next week. Checked the app and I only lost 1 percent so far. My business trips are never more than 2-3 weeks. I have zero anxiety leaving it at the airport. I'm going to start checking the 16v battery at the 4 year mark, but I do that with my gas cars too.
With my gas cars, I always back into my spot and bring my long jumper cables with me. That habit hasn't changed with my Tesla. Just pop the hood and wave your jumper cables in the air, there's always someone nice enough to give you a jump.

Or invest in a tiny, portable lithium battery booster, like those from Noco, and stash it in your frunk. Safer and faster than waiting for someone willing to jump start your car.

Left my 2022 M3 and 2023 MY in my driveway for 12 days, unplugged, charged to 55%. Average daily temp was in the mid 60s deg F. Checked both cars once on the app during the time away. Both cars showed 54% state of charge on arrival back home. Going forward I will not be concerned about leaving these cars unplugged for weeks at a time.
Just a supporting story.
Left at outside airport park & ride type lot for 2 weeks in middle of winter (MA so very cold out). There is a SC fairly close so felt fairly confident parking it but did not charge the car up before parking it.
I no longer recall the percentages/miles remaining but the moral of the story remains unchanged.
I believe I only checked miles remaining of charge not actual percentage of battery in the below examples.
Cannot recall exact state of charge when left but a week into trip I checked the app (had been delaying checking as I knew checking in on the car would cause some drain). Checking the app the battery had gotten quite low and I was panicked, at same rate of decline would be at zero before we flew home.
Turned off Sentry mode via the app - didn't really want to do that since it was a public parking lot but had no choice.
Nervously checked before flight home and battery was actually at a good amount higher remaining figure than when I checked last and remained at that rate when we arrived ; car was fine.
So three things ; Sentry mode can be a HUGE drain ; with Sentry off the car seems to lose almost no charge but the 3rd thing is the cars computer seems based on current conditions. The day mid trip when I checked it was 10 degrees F out at home or similar but at the end of our trip it was mid 40s or similar so I believe the car was estimating the miles remaining based on current conditions outside as well which can vary.
I believe the car alarm still is active/works even with Sentry off.
I also believe at some rate of charge the car will automatically turn Sentry mode off by itself.
