2013 S p85. car sat 7days @ Airport. charge was 70%, 60% after 7 days. does this mean I need new battery or hopefully something less expensive?

That is the generic HV battery warning. Yes, it most often means it’s time for a new HV battery.

In terms of your subject, in the summer here in TX, I'd allow up to 5% per day loss for the car cooling itself during the daytime heat. I just had a trip in June with covered parking and lost 2% per day (and that's with the car in deep sleep, I did not check it for a few days).

As far as the message in the picture in your post, agreed with ucmndd, probably a HV battery issue.

Would you care to share cars total miles, and maybe your charging habits?

That seems odd and contrary to my own experience. With cabin overheat protection off, my car does basically zero “cooling itself” whatsoever.

I just left my car for two weeks at my brother’s house while we were on a trip, outside in full sun, with ambient temps between 95-110 F.

I parked at 66% and returned to 61% 14 days later. It was over 150 degrees in the cabin when I unlocked the doors and woke the car up.

I do not have cabin overheat protection enabled, so I should have said "battery tending" instead of "cooling itself". When I've heard it, it's a fan running that isn't either of the cabin AC condenser fans.

I can't say I've seen 150 as a temp listed in the app...usually when I open the app to start the AC, it's in the 115-120 range. But 1-2% loss a day with no driving has been pretty consistent for me the past 2-3 years. For my June trip specifically, we parked at 61% and returned 6 days later to 49%.
