The battery gets depleted in my rivian pretty fast if it's sitting. I left it unplugged when I went out of town for 10 days and came back to a nearly dead truck. It depletes at around 4-8% per day even when parked in the garage and not in active use.

That seems wrong, might be worth getting it checked. (I have an EV but not a rivian)

  The technicians say it's working as intended, maybe I have a setting wrong? I'm sure it's doing ..something.. Shrug

    Tell them there is NO WAY that is normal. I have left my Renault Zoe for a month and a half with a few percent loss. You have a warranty issue. Get it fixed before it's too late.

      A Renault is kinda irrelevant, I have both a Rivian R1T and R1S. They both behave the same. It's really up to the manufacturer how active they want the system to be when it's sitting in park. I'm sure they could improve it, but as another poster mentioned, maybe it's in a sentry mode or similar. I have an e-bike that I almost never plug in and it holds its charge just fine with almost no depletion after several months of sitting. Your mileage will vary :)

Sounds like a Tesla with sentry mode on. IOW, there's something in your car that is running 24/7 that is using more than a trickle. Hopefully you can turn it off.

  Why does sentry mode need so much power? You’d think 20-30 watts to power the cameras, modem, and a small computer.

    Sentry mode requires the high voltage system to be on, most of the ~300 watts goes to conversion inefficiency in that system. (source: the internet, so...)

I’ve found that annoying in the Tesla too. Why does it need 2kwh to check in with the app once an hour overnight? I even made sure everything was turned off.

  That seems like a lot still - I’ve left mine parked at the airport for a week and seen no meaningful drain.

I have no idea if this is normal for a Rivian, but it sounds incredibly high. My Tesla M3 (LFP for the record, I doubt it matters) was parked in my garage for about 25 days while I was abroad and it lost about 2%. Not 2% per day, 2% overall. Recently I was away for a week and when I came back it was at the exact % I had left it.

Completely not my experience - 1 week if I leave mine at 100% it is like 97% when I get back.
