Unintentional vampire drain experiment

Some details - scroll down for the short version. Hope this provides some data on drain and aligns with what others are observing.

My R1T was recently in the shop. Upon completing the service, my truck was to be returned on the day I left for vacation.
This resulted in the R1T being dropped off in my driveway while I was flying to my vacation destination.

The R1T was charged to 100% by the Brooklyn service center on L2 power and reached 100% around 8am EST on Saturday August 6th. It was the loaded on a flatbed and delivered to my house around 12:30pm that same day. It was driven a few hundred feet from the flatbed service truck to my driveway.

This is where the truck sat until 2pm Sunday August 14th.

During this ~8 day stretch, the truck sat in the sun and reached internal temps of 120s-130s each day. It also received the latest software update that I kicked off from 1500 miles away. (took the estimated 75 minutes to complete).

Truck had 86% SOC when I got home around 2pm on the 14th.


Short version:
From Saturday August 6th at 8am, the R1T traveled less than 1 mile under its own power until Sunday August 14th at 2pm. It sat in the sun and elements the whole time. Firmware was also upgraded while it sat. State of charge went from 100% to 86% between that time period (6th to 14th).

Thank you, this is very helpful information.

1.75% of battery drain per day doesn't seem that bad. I guess what was surprising is when I did some rough math really just going on averages it's still somewhere between $80 and $100 a year of just vampire drain. I'm sure the majority of it is required but it's not like it's free.

I assume this means you were also pinging the truck a few times a day.

Did you receive the software update before the vehicle was delivered back or partially way through the vampire drain?

Wondering how much the software update helped with the drain. I think from the numbers you gave I'm happy to see what looks like an improvement over what we've heard in the past from others parking at airports.

Yes, I usually launched the Rivian app around lunch to check temps. Didn't think I pinged it much in the second half of the time period.

I updated the software partially through the vampire drain.
